Video Delivery Specs by Platform: The Last Place a Perfect Edit Goes Wrong
You can nail the edit and still wreck it at export. Here is a practical reference for video delivery specs by platform: aspect ratio, resolution, and codecs.
You spent two weeks on the edit. The color is dialed, the audio is clean, the client loves it. Then you export with the wrong codec, the file gets rejected, and you re-render at midnight before a morning deadline. Or worse: the upload goes through, but the platform crops it and cuts the subject's head off in the thumbnail.
Delivery specs are the least glamorous part of post and the most avoidable place a project dies. Nobody brags about getting the aspect ratio right. But getting video delivery specs by platform wrong is how a great edit becomes a soft, blocky, cropped embarrassment. Let me give you the practical version, the stuff that actually trips people up.
Match Aspect Ratio to the Destination First
The first decision is shape, and it is the one most people get wrong. Different platforms favor different frames, and uploading the wrong one triggers automatic cropping that does not care about your composition. It will cut off heads, slice text, and ruin a shot you spent an hour framing.
| Destination | Common aspect ratio |
|---|---|
| Widescreen players and standard YouTube | 16:9 |
| Vertical feeds, stories, and short-form | 9:16 |
| In-feed social posts | 1:1 or 4:5 |
If one video has to live in several places, you have two honest options. Either frame it so the important action survives a center crop, keeping faces and text away from the edges, or export tailored versions for each home. There is no third option where a 16:9 video magically looks right as a 9:16 story. Pretending otherwise is how subjects end up decapitated in the feed.
If a video must run in multiple aspect ratios, keep critical action out of the edges so a center crop does not destroy it, or just export a dedicated version per platform.
Get Resolution and Frame Rate Right
Deliver at the resolution your footage actually supports. Do not upscale a 1080p shoot to 4K hoping it looks sharper. Upscaling only softens the image and adds nothing. A genuinely sharp 1080p master beats a fake, mushy 4K every time.
Most platforms handle high resolution beautifully and downscale cleanly, so when you do have the real pixels, a sharp 4K master usually plays back crisper even on a small screen, because the platform has more detail to work with.
Frame rate is where stutter sneaks in. Keep it consistent from capture to delivery. If you shot 24, finish and export 24. Mixing frame rates, or converting them badly, introduces judder that makes motion look broken in a way viewers feel even when they cannot diagnose it. Whatever you shot, match it all the way through.
Export for Quality and Size at the Same Time
Use a widely supported codec, H.264 or H.265 for most delivery, and set a bitrate high enough to avoid visible compression artifacts. Watch the hard cases: fast motion and smooth gradients are where low bitrate shows up as blocking and banding. A sky or a slow push-in will expose a stingy bitrate immediately.
But do not blow past platform limits either. Every platform has file size and length caps. Exceed them and your upload either gets rejected or, worse, gets re-compressed harshly on their end, which undoes your careful work. The goal is the highest quality that still fits inside the platform's rules.
Label Your Exports or Pay for It Later
This one is pure discipline and it saves careers. Name every export clearly with the platform, the aspect ratio, and the version. A file called acme-launch-yt-16x9-v3 tells you everything. A file called final_FINAL_2 tells you nothing and is how the wrong cut goes to the wrong place. A good filename carries three things every time: the platform it is built for, the aspect ratio, and a version number, with no two exports ever sharing a vague name like final or final2.
Mini-scenario: you deliver three cuts for one campaign, a 16:9 for YouTube, a 9:16 for stories, and a 1:1 for feed. They all sit in one folder named export. Two days later you upload the wrong one to a paid placement, the client's logo gets cropped out of the corner, and you find out from an angry email. Clear filenames would have made that impossible.
Confirm the Right Cut Actually Ships
The most expensive delivery error is not a wrong codec. It is sending an outdated or unapproved version. You fix the client's last note, export, and then accidentally upload the cut from before the fix, the one still sitting in your downloads folder. Now the mistake is live for everyone to see.

Every version is stacked in order, the approved cut is locked and labeled, and there is zero doubt which file is the latest
With PlayPause, the final cut gets reviewed, commented on, and formally approved before it leaves your hands. Every version is stacked so it is obvious which one is current, and the approval lock means the file you export and upload is the exact one the client signed off on, not a stray draft hiding in a folder.
Bottom line: the edit is only half the job. Match the aspect ratio, deliver native resolution, hold your frame rate, export with a sane codec and bitrate, label everything, and confirm the approved cut is the one that ships. When you want zero doubt about which version is final, send your deliverables through PlayPause and let the approval lock do the remembering for you.
