The 30-second answer
Export at 1080p and 30 fps with quality set to high. That combination looks sharp on Instagram, TikTok, and YouTube Shorts, keeps file sizes manageable, and avoids the compatibility problems that 4K and HDR can cause. Burn captions into the export only when the platform you are posting to cannot show captions on its own; otherwise export a clean version and let the platform handle captions. If your video looks soft after uploading, the problem is almost always the platform’s recompression, not your export — always start from the highest-quality file you can make.
Export is the last step in every edit, and it is the one where good work most often gets quietly damaged. A video that looked crisp in the preview can come out soft, washed out, or oddly cropped, and the cause is usually one setting chosen in a hurry. The good news is that export settings are not complicated once you know what each one does. This guide explains resolution, frame rate, quality, HDR, and captions in plain language, gives you a default recipe that works for every major platform, and shows how to fix the export problems that actually happen.
One habit will save you more trouble than any single setting: always keep a high-quality master export. Upload a copy to each platform, but keep the best version on your phone or in cloud storage. If a platform mangles your upload, if you want to re-cut the video later, or if you need a version with different captions, the master is what makes all of that possible without starting over.
Resolution: 720p, 1080p, or 4K
Resolution is the number of pixels in your video, written as width × height. A vertical video exported at 1080p is 1080 pixels wide and 1920 tall — the native resolution of most phone screens and the size Instagram, TikTok, and YouTube Shorts all handle best. When you export below that, the platforms stretch your video to fill the screen, and fine detail like hair, text, and captions gets soft. When you export above it, most platforms shrink it back down anyway, so you pay for extra file size without a visible reward.
720p still has a place. It exports faster, uploads faster, and uses far less storage, which matters when you are on a slow connection or a phone that is nearly full. For drafts, quick tests, and videos that will only ever be watched on a small phone screen, 720p is perfectly watchable. Just do not use it for a final version you care about — side by side with 1080p, the difference in text sharpness is obvious.
1080p is the right default for nearly everyone. It matches what viewers actually see, keeps files a reasonable size, and is the resolution every major platform is tuned for. Unless you have a specific reason to choose something else, export at 1080p and spend your attention on lighting, audio, and pacing instead.
4K is worth it in exactly two situations: you want an archive-quality master you can re-cut later, or you plan to crop or zoom into footage in a future edit and need the extra pixels to stay sharp. For a normal social post, 4K roughly quadruples file size and export time, and the platform will downscale it to 1080p before anyone watches it. One more rule: never upscale. Exporting 720p footage at 1080p or 4K does not add detail — it only makes a bigger file of the same soft video. Export at the resolution you shot at, or lower.
Frame rate: 24, 30, or 60 fps
Frame rate is how many still images per second make up your video. The standard choices are 24, 30, and 60 frames per second (fps), and the golden rule is simple: match the frame rate you shot at. Converting between frame rates forces the app to invent or drop frames, which is how you get judder — that slightly stuttery look during camera moves.
30 fps is the social default. It looks smooth on phone screens, matches most phone camera defaults, and is what Instagram, TikTok, and YouTube Shorts all expect. If you are unsure, choose 30.
24 fps gives a film-like feel and is popular for cinematic edits, but on phone screens it can look slightly less smooth during fast movement. Use it deliberately, for a mood, not by accident.
60 fps is for motion: sports, dance, fast product shots, and anything you might slow down later. It doubles file size compared with 30 fps, and most platforms display it at 30 fps anyway, so its real value is in slow motion. If you plan a slow-motion section, shoot that section at 60 or 120 fps and keep the rest of the project at 30 — trimming and splitting first makes this easy to manage.
One practical warning: if your timeline mixes frame rates, check the export preview carefully around the joins. A clip that changes speed mid-sentence is the most common symptom of a frame-rate mismatch.
Quality, bitrate, and HDR
Quality is the setting most people skip, and it matters more than resolution. It controls how aggressively the video is compressed. High quality keeps more detail and produces a bigger file; low quality shrinks the file by throwing detail away, which shows up as blocky patches in gradients, skies, and dark scenes, and as fuzzy edges around text and titles.
Always export your master at the highest quality setting. Storage is cheap; a re-shoot is not. If the file is too big to upload comfortably, make a second, smaller copy for uploading and keep the high-quality master on your phone or in cloud storage. That way you can always re-upload or re-cut later without quality loss.
HDR is the setting to be careful with. High dynamic range video holds brighter highlights and richer color, but only on screens and platforms that support it end to end. On a standard screen, or on a platform that mishandles HDR, the same video can look washed out or oddly flat. Unless you have checked that your destination platform preserves HDR properly, export in standard dynamic range (SDR). A clean SDR export always looks good; a mishandled HDR export sometimes looks broken.
Before you export, check your free storage. A few minutes of high-quality 1080p can run to several hundred megabytes, and 4K HDR can pass a gigabyte. An export that fails halfway because the phone ran out of space is a frustrating way to lose ten minutes — clear space first.
Captions in your export
Captions deserve their own export decision, because you cannot undo it later. A burned-in caption is part of the video image itself: it shows on every screen, in every app, even with the sound off. A clean export has no captions in the picture, and captions are added separately by the platform you post to.
Burn captions in when the audience will watch with the sound off and the platform cannot add captions for you — for example, a video embedded on a website, or shared as a file. Keep the style simple and high-contrast, and check the timing on the exported file itself, because caption timing shifts if you re-cut after generating them.
Export clean when you are posting to Instagram, TikTok, or YouTube, all of which can display captions from their own systems. Platform captions are searchable, can be translated, and can be turned off by viewers who do not want them. Exporting clean also gives you a master you can caption differently for each platform.
The safest habit is to export both: a clean master first, then a captioned version. It costs one extra export and saves you from ever having to choose between a version with permanent captions and no captions at all.
Export settings for each platform
Instagram Reels, TikTok, and YouTube Shorts all want the same thing: vertical video, 1080 × 1920, 30 fps, high quality. That is convenient — one export serves all three. Upload over Wi-Fi when you can, and in Instagram’s settings turn on high-quality uploads so the app does not shrink your video before it even reaches Instagram’s servers.
Where the platforms differ is what happens after upload. Each one recompresses your video to its own specifications, and that second compression is where most complaints about blurry video come from. Starting from a high-quality export gives that recompression the most detail to work with, which is why a sharp master matters even though the platform will compress it again.
For anything that is not a short vertical video — a landscape clip for YouTube, a square clip for a feed post — the same rules apply, just with the dimensions changed. Export at the platform’s native aspect ratio, keep 30 fps and high quality, and check the result on the platform itself before you assume it is right. Aspect ratio mistakes are easy to miss on a phone preview and obvious once posted.
Finally, watch your audio. Export with the original audio track intact, and if you added music or voiceover, listen to the exported file end to end at least once. Export is the last chance to catch a clipped word, a music track that starts too loud, or a section where the audio drops out.
Fix common export problems
The video looks blurry after uploading. This is almost always platform recompression, not your export. Re-upload from your high-quality master over Wi-Fi with high-quality uploads enabled, and compare. If the master itself is blurry, you exported below your source resolution — re-export at 1080p.
The file is too large to send or upload. Drop from 4K to 1080p first; that alone usually cuts the file to about a quarter of its size. If it is still too big, lower the quality one notch rather than dropping resolution — a slightly more compressed 1080p file looks better than a clean 720p one.
Audio drifts out of sync. Restart the app and re-export; a one-off export glitch is the most common cause. If it persists, check for a frame-rate mismatch between your clips and your project, and re-cut the problem section rather than trying to patch the exported file.
HDR video looks washed out. The platform or screen is not handling HDR. Export an SDR version and use that for posting; keep the HDR master only if you have a destination that supports it.
Captions are missing from the export. You exported the clean version. Re-export with captions turned on, and double-check the caption track is enabled before you tap export — it is easy to leave it off after previewing a clean cut.
Frequently asked questions
What are the best export settings for Instagram Reels?
1080 × 1920, 30 fps, high quality, SDR. Upload over Wi-Fi with high-quality uploads enabled in Instagram’s settings.
Why does my video look worse after I post it?
Every platform recompresses uploads. Start from the highest-quality export you can make, because recompression of a sharp file looks far better than recompression of an already-compressed one.
Is 4K worth it for social media?
Usually not for the post itself — platforms downscale to 1080p. It is worth it for a master copy you plan to archive or re-cut later.
Should I export with HDR on?
Only if you know the destination preserves HDR end to end. For general posting, SDR is the safer choice and always looks correct.
How do I make an export file smaller?
Export at 1080p instead of 4K first, then lower the quality setting one step. Trim dead footage before exporting — every second you cut shrinks the file.
