For most web and social publishing, use an MP4 file with H.264 video as a practical delivery default, then export the aspect ratio and dimensions that suit each destination. It is not a universal choice for camera originals, editing masters, every platform, or presentation software: check the destination’s current requirements and test playback where the video will be shown.
Start with the destination, not a supposed universal format
“Video format” can mean several different things. MP4 is a container—the file wrapper—while H.264 is a video codec that compresses the picture inside it. Aspect ratio and pixel dimensions determine the shape and size of the image; frame rate describes how many frames are shown per second. These settings solve different problems, so choosing MP4 alone does not settle the export.

YouTube’s upload guidance recommends an MP4 container, H.264 video, progressive scan, and a frame rate matching the source recording. Adobe also identifies MP4 as its best web video file format in social editing guidance. Together, these make MP4/H.264 a sensible delivery starting point for many web and social videos—not a rule for every workflow or platform. YouTube’s encoding recommendations and Adobe’s video-format guidance explain their respective recommendations.

Match the picture shape to the placement
Choose landscape, vertical, or square based on where viewers will see the video. Common starting points are 16:9 landscape for website players and horizontal viewing, 9:16 vertical for TikTok, Reels, and Stories, and 1:1 square for square-feed placements. These are workflow examples, not guarantees that a platform accepts every dimension or placement in that shape. Confirm the current requirements for the exact destination before exporting.
#1 Best Overall
Adobe’s 12 December 2022 examples list 1920×1080 horizontal for Facebook feeds, YouTube, LinkedIn, and Twitter; 1080×1920 vertical for TikTok, Instagram Reels, and Stories; and 1000×1000 square for Instagram feeds. Because those examples are dated, treat them as canvas illustrations rather than current platform specifications. Adobe’s social-media video-size guide provides the examples. Microsoft’s current article reproduces a table attributed to Sprout Social, but says it covers general videos rather than ads, Shorts, or Reels; it is not a substitute for a platform’s own placement-specific rules. Microsoft’s social video size overview describes that scope.
Reframe with the subject in mind
A landscape stock clip can sometimes be cropped into a vertical or square version, but the crop may cut out the subject or important context. Inspect the reframed export, not just the source preview. If a vertical placement matters, a clip captured natively in 9:16 is more likely to preserve the intended composition than a rotated or tightly cropped horizontal shot.
Compare stock clips before editing
When several clips could work, compare their technical properties against the destination and project rather than choosing by resolution alone.
- Orientation and aspect ratio: Does the clip’s shape suit the intended placement? If not, is there enough room around the subject to crop?
- Native resolution: Does the source have enough pixels for the output, and will reframing reduce useful detail?
- Frame rate: Does it fit the motion and timeline you need? For YouTube delivery, encode at the rate at which the footage was recorded.
- Container and codec: Can your editor open the file, and does the export meet the destination’s current guidance?
- Bitrate and file size: Higher resolution and bitrate generally mean larger files; account for upload limits, storage, and playback needs.
- License: Confirm that the stock footage’s terms permit the intended use. Technical suitability does not grant usage rights.
Adobe Stock describes licensed stock footage as one way to fill gaps in a video. Read the applicable license terms for the particular asset and use; format guidance alone cannot determine whether a use is permitted. Adobe’s stock video overview discusses the workflow.
Rank #3
For YouTube, follow its upload guidance
YouTube recommends MP4 with H.264 video, progressive scan, and a source-matched frame rate. It also advises deinterlacing interlaced footage. Keep those recommendations distinct from stock-library submission rules: they address YouTube uploads, not every editor, website, or social placement.
For SDR uploads, YouTube’s reference bitrate table gives these recommendations. They are guidance values, not universal upload requirements or guarantees of a particular visual result. YouTube’s encoding recommendations includes the complete guidance.

| Resolution | Standard frame rates | High frame rates |
|---|---|---|
| 1080p | 8 Mbps at 24, 25, or 30 fps | 12 Mbps at 48, 50, or 60 fps |
| 2160p (4K) | 35–45 Mbps | 53–68 Mbps |
The table is for SDR; YouTube lists different values for HDR. A higher bitrate can increase file size, so do not apply the 4K figures to a 1080p export or treat them as cross-platform presets.

If you are choosing or preparing footage for Adobe Stock submission, its specifications are a separate case from exporting a finished video to YouTube or social media. Adobe Stock’s page, last updated 2 September 2026, accepts MOV, MPG, or MP4 and recommends ProRes or H.264 codecs. Its listed standard frame rates are 23.98, 24, 25, 29.97, 30, 50, 59.94, or 60 fps. These are contributor specifications, not a universal checklist for people downloading stock clips. Adobe Stock’s video requirements has the current details.
Adobe Stock advises contributors to upload footage at native frame size, shoot vertical clips natively in 9:16 rather than rotating horizontal footage, and use 1:1 for square clips. Its examples include these dimensions:
| Orientation | Adobe Stock examples |
|---|---|
| Horizontal | 1920×1080 HD; 2048×1080 2K; 3840×2160 UHD; 4096×2160 4K; 4096×2304 4K 16:9 |
| Vertical | 1080×1920; 2160×3840 |
| Square | 1080×1080; 2160×2160 |
Those dimensions and file specifications describe submissions to Adobe Stock. A finished video still needs to be exported for the platform and placement where it will be delivered.
For presentations, test on the actual setup
There is no established universal container-and-codec setting here for every presentation application and playback device. Before presenting, test the exported file in the software and on the device you will actually use. If playback or embedding fails, consult that application’s current official media guidance and try a compatible export rather than assuming a setting recommended for YouTube will solve it.

A compressed delivery export is convenient to upload and share, but it is not a substitute for retaining the source files when future edits or repurposing matter. Adobe recommends keeping three copies in at least two places, with one copy physically separate. This is a backup-workflow suggestion, not a required video format. Adobe’s guide to backing up video files describes that approach.
