What a Steam Trailer Has to Do: Valve's 2026 Specs and Autoplay, the First Five Seconds, Trailer Order, Hiring and Briefing an Editor, and a Wishlist Conversion Test

The first moving image a visitor sees on a Steam store page is the trailer. According to Valve's Steamworks documentation, the first two valid trailers appear before the screenshots, and someone flicking through the Discovery Queue may give you less than 10 seconds to make an impression. On top of that, Steam automatically builds a six-second microtrailer from six one-second clips of your first visible trailer, and uses it on category hubs and sale pages. One video ends up doing two jobs at once: converting visits on the page and earning attention off it.

Yet trailers are usually judged as "a good-looking video." The cinematic made for a publishing announcement or a showcase goes straight into the first slot, and vendor quotes get compared on runtime and polish. This post treats the Steam trailer as a video asset whose job is to turn visits into wishlists. Based on Valve's official documentation as of November 2026, it covers the specs and autoplay behavior, how to structure the first seconds, length and order, reuse for Next Fest, showcases, and paid ads, who to hire and what to put in the brief, and how to verify a trailer change through wishlist conversion rate.

How to audit the whole store page for wishlists (the audit table, screenshots, short description, tags, localization) was covered in What a Steam Store Page Has to Do to Turn Visits Into Wishlists: Measuring Wishlist Rate, What to Fix First, Who to Hire, and a 4-Week Test Plan. This post takes the one item that audit marked as high priority, the trailer, and goes deep on it. The capsule that earns the click in the first place is covered in What Steam Capsule Art Has to Do: 2026 Sizes and Valve's Rules, Choosing and Briefing an Artist, Testing Without an A/B Tool, and Wishlist Conversion Data.

How Does a Steam Trailer Play on the Store Page? Valve's Specs and Autoplay as of November 2026

A Steam trailer should be uploaded as 16:9 video, up to 1920×1080, at 30 or 60 fps, with a high bit rate of 5,000 Kbps or more. Only the first two sit ahead of the screenshots, and the first one becomes the source of the microtrailer. Here is what Valve's documentation specifies.

Item

Per Valve's documentation (checked November 2026)

What it means in practice

File format

.mov, .wmv, .mp4. H.264 video and AAC audio preferred

Default exports from most editors are fine

Resolution and frame rate

Highest you have, up to 1920×1080. 30/29.97 or 60/59.94 fps

Uploading 4K gains nothing. 1080p is the ceiling

Bit rate

5,000+ Kbps. Adobe preset example: H.264 at 20 Mbps, AAC stereo at 192 Kbps

Games with fast combat or heavy particles need headroom

Aspect ratio

16:9 preferred, 4:3 accepted

Vertical ad cuts need a separate edit

Audio

Reduced to regular stereo during transcoding. 44 kHz or 48 kHz

A surround mix is wasted

Category

General/Cinematic, Teaser, Gameplay, Interview/Dev Diary

The first trailer naturally belongs under Gameplay

Order

Drag and drop. Only the first two valid trailers appear before screenshots; the rest follow them

Assume most visitors never see the third onward

Recommended content

First trailer primarily gameplay, with HUD visible. Should work without audio

Carry key messages in captions or on-screen text

Microtrailer

Six-second loop built automatically from six one-second clips of the first visible trailer. Not customizable. Shown on category hubs, special sale pages, and the homepage during seasonal sales

Any one second of the first trailer should show gameplay

Thumbnail

600×380 poster and 232×130 thumbnail auto-generated. Custom images must be a frame from the video, 1920×1080 .jpg/.png, ideally without text

Pick a gameplay frame, not a logo card

Language and region

Assign trailers to languages in Advanced Settings; the base video should be English. Rated videos can be limited by country code

The "first two" may differ by country depending on these settings

Release and processing

Cannot release while a trailer is converting. Processing is first-in, first-out; deleting and resubmitting sends it to the back of the queue

Swapping right before launch or an event is risky. Leave days of slack

The item teams miss most often is the microtrailer. Valve says only that it takes six one-second clips from the first visible trailer; it does not disclose which points it samples. If your first trailer is full of logos, black frames, title cards, and slow scenic pans, those moments can end up in the microtrailer too. That is a reason beyond the page itself to make the first trailer gameplay-dense from start to finish.

Autoplay is not specified in Valve's documentation. Third-party analytics tool Steam Page Analyzer states in its guide, updated September 2026, that Steam plays the first trailer muted at the top of the store page, and Steam Community answers going back years describe an "Autoplay videos" checkbox in the bar that appears when you hover over the video, ticked by default, which stops autoplay when unticked. Put together, most visitors see the opening of your first trailer without sound, and the minority who have turned autoplay off judge you on screenshots instead. That is why Valve says to make trailers that communicate without audio, and why screenshots deserve as much attention as the trailer.

One more rule is worth remembering. When Valve introduced the "two trailers before screenshots" rule in May 2023, PCGamesInsider reported that Valve also recommended saving company logos and narrative for later in the trailer. If your page was built before that change, start by checking what currently sits in the top two slots.

What Belongs in the First Five Seconds? Gameplay First, and Where Cinematics Fit

The first five seconds should show gameplay with the player in control, and logos and lore should come later. That is the shared conclusion of Valve's guidance and current industry advice. It should be said up front, though, that this is mostly practitioner experience; there is no public large-scale data linking trailer structure to wishlist conversion. Steam Page Analyzer says in the same guide that neither Valve nor anyone else publishes trailer conversion data at scale.

Taken one by one, the sources point the same way. Valve recommends a first trailer that is primarily gameplay, with HUD visible. Chris Zukowski of How To Market A Game wrote in March 2025 that Steam shoppers can tell a cutscene from gameplay and want gameplay to verify the genre, the quality, and the fun, and he set "show gameplay in the first 5 seconds" as a rule. Trailer editor Derek Lieu wrote in a 2021 Game Developer piece that many viewers never turn on sound, likened a minimal Steam page trailer to "a glorified animated GIF," and suggested keeping each shot around 3 to 5 seconds so viewers who click through the progress bar do not miss anything. Simon Carless of GameDiscoverCo argued in 2022 that movie-style slow-burn trailers in which gameplay arrives 15 to 30 seconds in lose Steam viewers.

Mapped onto a timeline, that advice gives the following skeleton. The time bands follow the structure Steam Page Analyzer proposes, which the company itself labels as craft convention rather than measured results.

Segment

What goes in

What to avoid

0 to 5 seconds

The most representative core gameplay, HUD included. A shot that tells you what the game is with the sound off

Publisher or studio logos, fade-ins, title cards, lore narration

5 to 15 seconds

Lock in genre, perspective, and the core loop (what the player does over and over)

Repeated shots, scenery with no player interaction

15 to 60 seconds

Variety and differentiators: other areas, enemies, tools, signs of progression. Compress differentiators to one to three

Feature lists, showing any element more than three times

Final 10 to 15 seconds

A climactic moment, the title, release timing, a wishlist call to action. Logo for 2 to 3 seconds at most

Long credits, a wall of social links

This does not make cinematics useless. The line Carless and Lieu draw is about context. In a showcase, where viewers have committed to watching the whole thing, a slow build can work; on a Steam page the same video invites a bounce. Lieu recommends that the first trailer be "gameplay gameplay gameplay," with a second, deeper trailer if needed, and treats story and cinematics as nice-to-haves when they support the core loop. There is a middle path as well. GameDiscoverCo highlighted that Spelunky 2 put a developer commentary trailer first: muted, it looks like raw gameplay, and with sound on you hear the developer explaining the game.

If you assume silent viewing, on-screen text matters more, but text that covers the gameplay defeats the purpose. One or two short lines naming the genre or core verb, plus the title and release timing at the end, is usually enough. If you plan language-specific trailers, keep text on separate layers in the edit project so localization stays cheap.

How Long Should a Steam Trailer Be, and How Many Should You Upload in What Order?

Start the first store page trailer at around a minute and extend it only as far as the game's variety allows, and put two trailers in the top slots: a gameplay-first trailer and a second one that shows depth. Length advice varies a lot by source, so it helps to see the context behind each number.

Derek Lieu, Game Developer (April 2021)

Offered as craft convention, no measured data

How To Market A Game showcase analysis (September 2025)

Around one minute. Longer trailers did not perform better

Viewer retention and follower gains for showcase trailers

The numbers differ but the principle is the same: stop when you run out of new things to show. Lieu says not to show any element more than three times, and in Zukowski's showcase analysis a 3:23 trailer lost viewers steadily while the same game's 1:30 version held them. Length is better decided by "how many seconds of new material does our game have" than by "what is the right number of seconds."

For trailer count, the distribution across real pages is a useful reference. Steam Page Analyzer counted videos on 405 Steam store pages between February and July 2026: 180 released pages averaged 2.4 videos (median 2), and 225 unreleased pages averaged 1.2 (median 1). In a separate sample, 27 of 286 unreleased pages (9.4%) had no video at all, versus 2 of 242 released pages (0.8%). Zukowski notes that Valve no longer requires a trailer for page approval, but still recommends making one, even a short one, because a page without a trailer can look less serious. And as the next section shows, Next Fest requires a public trailer.

Set the order by purpose. The default is a Steam page gameplay trailer in slot one and a deep-dive or latest update or launch trailer in slot two. Announcement cinematics, showcase cuts, interviews, and dev diaries go third or later, behind the screenshots. Carless also flagged piling up trailers without removing old ones as a common mistake. After launch it is tempting to move the launch trailer to the top; if that video is not gameplay-led, keep the first slot as is and put the launch trailer second. And remember that changing the first slot also changes the microtrailer.

Language settings affect the order. When you assign trailers to languages or countries, which two appear first depends on the visitor's settings; without restrictions, the first two listed are shown. If you made a version with subtitles in a top wishlist region's language, check that it actually lands in the first slot there. Valve's figures shared at Devcom in August 2025 put Simplified Chinese at 33.6% and English at 33% of Steam users' primary languages, so a setup that relies on English captions alone may miss more visitors than you would think.

How Do You Reuse One Trailer for Next Fest, Showcases, and Paid Ads?

Cut multiple versions from the same footage, treat the store page first trailer as the master, and re-edit length, aspect ratio, and opening shot for each event or ad placement. Viewing conditions differ by venue.

Next Fest is the simplest call. Valve's Next Fest documentation lists, among the eligibility requirements, having at least one publicly visible trailer on the base game store page before registration closes, and states that Next Fest uses the trailer on your store page and cannot accept alternative videos. The microtrailer is again generated automatically from the store page's first video and cannot be customized. In other words, you do not make a Next Fest trailer; your first trailer at Next Fest time is your festival trailer. On Valve's calendar as of November 2026, the next Next Fest runs February 22 to March 1, 2027, and Valve's documentation puts demo build submission at typically three weeks before the event (five weeks if the demo goes public before Press Preview). Check that edition's page for its registration deadline. Finish any trailer swap ahead of registration and demo deadlines, with slack for processing time. Festival preparation overall is covered in Steam Next Fest Marketing.

Showcases call for the opposite edit. Viewers are prepared to watch to the end, so a short lead-in is acceptable, but that is not a license to run long. How To Market A Game's analysis of spring 2025 showcase entries (updated January 2026) found that the top 48-hour Steam follower gain was 5,320, and that a trailer built on lore narration and slow pans with barely any gameplay saw a marked decline in viewers. The author recommended around one minute and noted that DLC or update trailers for already released games tended to underperform. Showcase slots are also expensive. Game Developer, citing Esquire in June 2024, reported Summer Game Fest trailer slots at $250,000 for one minute, $350,000 for 90 seconds, and $550,000 for two and a half minutes. If you spend at that level, make sure the first trailer waiting on your store page for the post-showcase wave is a gameplay cut. Putting the showcase cut in slot one means showing a slow opening, again, to visitors you paid dearly to bring in.

Paid ads start with a different aspect ratio. TikTok's ad specifications label vertical 9:16 (at least 540×960) as the recommended format, while also accepting 16:9 and 1:1. Placing a 16:9 store trailer in a vertical slot leaves most of the screen empty, so a separate 15 to 30 second vertical cut built around core gameplay works better. Tag each cut's store link with a different utm_content value and Steam UTM Analytics will let you compare wishlist conversion by cut. Per Valve's documentation, UTM conversions count only logged-in visits and attribute wishlists, purchases, and activations within 72 hours of the click, so use the data for relative comparisons between cuts rather than absolute numbers.

Should You Use In-House, a Freelance Editor, or a Trailer Studio?

If you have plenty of captured gameplay and plan to update the page often, in-house or a freelance editor fits. If you need capture, sound, subtitles, and language versions in one package, or a major reveal is at stake, a specialist trailer studio fits. Either way, the deciding criterion is experience making gameplay-first Steam page trailers, not budget.

Cost evidence needs its limits stated first. There is no public standard rate, and most available numbers are estimates from the people selling the service. In addition to the vendor estimates cited in the store page post ($5,000 to $20,000+ for a one-minute trailer, $300 to $1,500 per minute for editing and compositing alone, $4,000 to $10,000 for a gameplay showcase), here is what we were able to verify this time. Steam Page Analyzer's 2026 guide gives a professional editor at $1,000 to $5,000 in the body and $1,000 to $2,000 in its FAQ, so its own ranges conflict. Video production company Beverly Boy Productions, in a post updated August 2024, put general live video production without animation at roughly $1,000 to $10,000 per finished minute, motion graphics at $3,000 to $5,000 per minute, and 3D animation at $10,000 to $20,000 per minute. At the other extreme is a 2016 Game Developer write-up of a trailer made for $100 ($20 for music, $80 for voice-over, the rest from friends). The realistic takeaway is that editing captured gameplay lands in the hundreds to low thousands of dollars, and new animation or 3D cinematics push into five figures per minute. The actual decision should come from two or three quotes for the same scope, side by side.

Agreement that this video does not go in the store page's first slot

Searches for "game trailer maker" also surface tools, but a tool only shortens editing time; it does not decide which shot goes in the first five seconds. Whether you build in-house or hire out, structure gets decided in the brief.

A brief should include at least the following: where the trailer will live (store slot one, slot two, a showcase, ads) and the viewing conditions there; your top five tags and two or three comparable games; a one-sentence description of the core loop and one to three differentiators; candidate shots for the first five seconds; HUD elements that must be visible; the messages and on-screen text that must land with the sound off; target and maximum length; the list of derivative versions such as language subtitles and vertical ad cuts; the capture footage and build you will provide; deadlines (Next Fest registration, events, launch date) and an upload date that accounts for processing; commercial rights to project files and music; and how success will be judged, namely the visit-to-wishlist rate before and after the swap. Writing that last item into the brief shifts the conversation with your editor from "does it look cool" to "what is visible in the first five seconds."

It also helps to know the red flags when choosing a vendor. A portfolio of showcase cinematics with no gameplay trailers that actually ran in a Steam page's first slot. A proposal to open the first trailer with a logo or narration. Unfamiliarity with microtrailers or muted autoplay. An inability to explain music licensing scope (store page, YouTube, and ads all covered?). Withholding project files, so no one else can make language versions or ad cuts later. And talking only about view counts when asked how success will be measured. View counts say nothing about whether a trailer turned visits into wishlists.

How Do You Measure the Effect of a Trailer Swap? A Before-and-After Wishlist Conversion Plan

Steam has no trailer A/B testing, so the realistic approach is a sequential test: change only the trailer order or the first trailer, leave everything else alone, and compare visit-to-wishlist rates by source before and after. Visits come from Steamworks' traffic reports and wishlist adds from the wishlist report, and you divide them yourself. Valve defines a visit as a unique load of the store page. Conversion rate math and the limits of benchmarks are covered in detail in the store page post, so this section sticks to what a trailer test needs.

Week 1

Upload the new first trailer without moving it to slot one yet (confirm processing is done). Run external ad cuts first, each with its own utm_content link

Weeks 2 to 3

Swap slot one only. Do not touch the capsule, screenshots, short description, tags, or discounts. Log visits, wishlists, and deletions by source weekly, on the same weekday

Weekly log

Week 4

Compare with the baseline and keep or revert. Keep only if at least two major sources moved the same way and a shift in traffic mix does not explain it

Decision, next swap candidate

Breaking results out by source matters because a trailer's effect shows up differently by source. Visitors arriving fresh from the Discovery Queue or tag pages are more likely to judge on the trailer's opening, while visitors from wishlist discount emails or the follow feed are already interested. Expect the effect of a swap to appear first in the former. Reading traffic by surface is covered in Who Does Steam Show Your Game To? Choosing and Ordering Tags in 2026, the Visibility Signals Valve Has Confirmed, and How to Audit Discovery in Steamworks Traffic Reports.

Schedule around Valve's calendar as of November 2026: Auto-Battler RPG Fest from November 16 to 23, the Winter Sale from December 17 to January 4, 2027, then Desktop Companion Fest January 14 to 18, Shop Keeper Fest January 25 to February 1, Sheep Fest February 4 to 8, and Couch Co-Op Fest February 8 to 15, with Next Fest starting February 22. If you are not joining a genre fest, late November to mid-December is a relatively clean window, and early to mid-January after the Winter Sale is a second one. If you are entering February Next Fest, finish the first-trailer swap and its verification in January, so the event shows an already-proven trailer and microtrailer. Swapping the first trailer during a festival or sale makes it impossible to separate the event's effect from the swap's.

Mind your sample size too. At a few hundred visits a week, a handful of wishlists can swing the rate a lot, so extend observation to 6 to 8 weeks or time the swap just before a traffic spike. Per-cut UTM comparisons from external ads complement the sequential test. Run two or three vertical cuts first, find the opening that earns the best wishlist conversion by utm_content, and fold that opening into the first five seconds of the store trailer. That lets you check direction before touching the page. Ad traffic and in-Steam traffic come with different context, though, so treat the result as a hypothesis, not a conclusion. Finally, if wishlists rise, watch wishlist deletions as well. A trailer that sets expectations the game does not meet is followed by more deletions.

After the Trailer Converts: Playio's Perspective

Once the trailer lifts the rate at which visits become wishlists, the next job is bringing more players whose tastes match to that page, and making sure the resulting wishlists turn into launch-day purchases and real playtime. The better your proven conversion rate, the more each additional visit is worth, which makes the point right after a trailer test the best time to spend on external traffic.

Playio is a game community of 5 million gamers, where AI analyzes genre preferences, play history, and in-game behavior data to match games with players who fit them. Its Steam product for PC Steam games lets you set each funnel action as a campaign goal: wishlist and follow, add to cart, purchase, playtime milestones, and achievement completion. Billing is CPI by default, with CPE available for specific actions. From a trailer perspective, this structure helps in two ways. Because visitors are selected by genre taste, you get a separate source for checking whether the game your new trailer promises matches what visitors expect. And because the same campaign carries through to purchase and playtime instead of stopping at wishlists, you can judge whether the expectations the trailer created turned into actual play.

We recommend lining this up with the measurement plan above. Set the baseline for the trailer swap first, and route Playio campaign traffic only through dedicated UTM links so it can be separated in Steam UTM Analytics. That keeps the trailer swap's effect and the external campaign's effect from blending, and puts Playio traffic's wishlist conversion side by side with other sources. If you are preparing for February Next Fest, a natural setup is to finish trailer verification in January, then attach a campaign targeting wishlists and demo plays just before and during the event.

As a concrete next step, send your game's genre and top five tags, Steam store page link, the current top two trailers and your swap plan, visits by source over the last four weeks with wishlist adds for the same period, top wishlist countries, and your Next Fest or launch schedule to [email protected]. We will send back a before-and-after measurement design for the trailer swap (UTM structure and comparison windows) along with a wishlist funnel pilot proposal (goal actions and billing steps, with decision rules based on purchases and playtime rather than wishlist counts).

Key Takeaways

As of November 2026, Steam trailers are uploaded as 16:9 video up to 1920×1080 at 30 or 60 fps and 5,000+ Kbps. Only the first two valid trailers appear before the screenshots, and a six-second microtrailer built automatically from six one-second clips of the first trailer is used on category hubs and sale pages. Autoplay is not specified in Valve's documentation, but most visitors see the first trailer without sound, so the rule is to put core gameplay with the HUD visible in the first five seconds and move logos and lore narration later. Length advice ranges from 30 to 180 seconds depending on the source, but every source agrees on stopping when new material runs out, and the top two slots are best filled with a gameplay trailer and a deep-dive or update trailer. Next Fest accepts no separate video and uses your store page trailer as is, so verify the first trailer before the event; showcase and vertical ad cuts are re-edited from the same footage for length, aspect ratio, and opening. Outsourcing costs have no public standard and vendor estimates spread from hundreds to low thousands of dollars for editing up to five figures per minute for animation, so write the placement, viewing conditions, first five seconds, derivative versions, and success criteria into the brief and compare quotes for the same scope. Verify the effect with a sequential test that changes only the first slot, comparing visit-to-wishlist rate by source, and make the final call on whether wishlists turn into purchases and play.
