30-second answer: Edits export settings control how sharp, smooth, and large your finished video will be. As a rule, export at the resolution you recorded in — usually 1080p — with the highest quality setting you can tolerate for file size, and check the exported file before you post. Exporting at a higher resolution than your footage does not add detail, and exporting at a much lower quality setting is the most common cause of a video that looked sharp in the app but blurry after posting.

Exporting is the last creative decision in a project, and it is easy to treat as an afterthought. You tap export, accept whatever is selected, and only discover the problem after posting, when the video looks soft, the text is hard to read, or the file will not upload. A few minutes spent understanding the settings prevents that, and it also prevents the opposite problem: exporting enormous files that take forever to upload and gain nothing in visible quality.
Think of export settings as a balance between three things: detail, smoothness, and size. Resolution controls detail, frame rate controls smoothness, and the quality or compression setting controls how much of that detail survives into the final file. Changing one affects the others, so the right choice depends on your footage and where the video will be seen. Edits runs on your phone, so these choices are made in the app’s export screen, not on a computer.
Step 1: Choose the right resolution
Resolution is the number of pixels in each frame, such as 720p, 1080p, or 4K. For most phone-shot social video, 1080p is the sensible default: it looks sharp on phones and larger screens, and it keeps file sizes manageable. Use 720p only when you need a much smaller file, for example for a quick draft or a slow connection, and accept that fine detail, such as small caption text, will suffer.
Do not export at a higher resolution than you recorded. If your clips were shot at 1080p, exporting at 4K will not invent detail that was never captured; it will only create a larger file with the same picture, slightly softened by upscaling. The exception is when you recorded at 4K and want to keep that detail, in which case export at 4K and accept the larger file. As a habit, check what resolution your source clips actually are before you choose an export resolution, rather than assuming.
Step 2: Understand quality and compression
Quality settings control compression: how aggressively the app squeezes the video data into a smaller file. Higher quality means less compression, more detail, and a larger file. Lower quality means more compression, a smaller file, and visible artefacts — blockiness in flat areas, smearing in fast movement, and soft edges around text. The difference is most obvious in busy scenes, such as moving water, crowds, or fast camera movement, where compression has to work hardest.
When in doubt, choose the higher quality option and let file size be the consequence, not the goal. Storage and upload time are temporary costs; a blurry posted video is permanent, at least for that post. If you must reduce quality, do it in one step and then check the result on a real screen, rather than guessing. A small quality reduction is often invisible, but a large one rarely is, especially on captions and titles, which are the first things to look soft.
Step 3: Control file size without ruining quality
File size grows with resolution, length, frame rate, and quality, so the most effective way to shrink a file is usually to shorten the video, not to crush its quality. Trim dead air first, using our trim and split tutorial, and you will often cut the file size more than any quality slider would, while improving the video itself. Next, consider whether you need the highest resolution for this particular post; a draft for review can be smaller than the final version.
Also check for hidden size drivers: long silent sections, repeated footage, and unnecessarily long endings all add megabytes without adding value. If a video is still too large after trimming, reduce quality by one step at a time and re-check, rather than jumping to the lowest setting. Keep a note of the settings that worked for a typical video of yours, so you do not have to experiment from scratch every time.
Step 4: Match settings to where you will post
Different destinations treat video differently. A platform may recompress your upload, which means a slightly higher-quality export gives the platform more to work with, and the final result looks better than if you had already compressed heavily yourself. Posting the same file to several places is usually fine, but if one destination has a strict file-size or duration limit, export a separate, smaller version for that destination rather than compromising the main export.
Also think about how viewers will watch. A video mostly watched on phones does not need the same settings as one that will be shown on a large screen, but in practice 1080p with good quality covers both well. If your video relies on fine detail — small text, product close-ups, or intricate graphics — prioritise quality over file size for that project, even if it means a slower upload. The detail is the point of the video, so protecting it matters more than saving a few minutes.
Step 5: Fix blurry, huge, or failed exports
If an export looks blurry, work backwards. First, check the exported file, not the in-app preview, because previews can be sharper or softer than the final file. Next, confirm the export resolution matches or exceeds your source resolution, and that the quality setting was not accidentally left on low. Then check the source footage itself: if the original clip was already soft, no export setting will fix it, and the real fix is better lighting or a steadier shot next time.
If a file is unexpectedly huge, check duration and resolution first, then quality. A 4K export of a long video will always be large, and that is normal, not a fault. If an export fails or stalls, free up storage on your phone, close other apps, and try again with the same settings before changing them — a failed export is often a storage or memory issue, not a settings issue. If it fails repeatedly at high settings, export at one step lower and check whether the visible difference matters.
Step 6: Check the exported file properly
Never post straight from the export screen without checking the file. Play the exported video in full, on your phone, at full size, with sound on and then with sound off, reading the captions as in our captions tutorial. Look for blurry text, blocky movement, audio that drifts out of sync, and any frame where the picture freezes or stutters. These problems are much easier to fix before posting than after.
Check the file size and duration too, and confirm the file is the version you think it is. It is surprisingly easy to post an earlier draft by mistake, especially when several exports with similar names are in your camera roll. Rename or move the final export, or delete obvious drafts, so the file you post is the one you checked. A two-minute check here saves the embarrassment of a public correction later.
Common export mistakes
The most common mistake is exporting at the lowest quality to save time, then wondering why the video looks soft. The second is exporting at maximum settings for every video, including quick drafts, and then struggling with uploads and storage. The third is judging quality from a tiny preview thumbnail, which hides exactly the artefacts that matter. The fourth is forgetting that the platform will recompress the video anyway, and therefore over-optimising for a perfection that the destination will not preserve.
Another mistake is changing several settings at once when something goes wrong. If an export looks bad, change one setting, re-export, and compare, so you learn what actually caused the problem. Otherwise you may “fix” a blurry export by changing resolution, quality, and frame rate together, and never know which change mattered — which means you will make the same mistake on the next project.
Using this in a desktop workflow
Export review is where a desktop setup earns its keep. After exporting from Edits, transfer the file to your computer and watch it on a larger screen, where compression artefacts, soft text, and audio issues are far easier to spot than on a phone. Keep a folder of exports with names that include the date, the project, and the settings used, so you can compare versions and learn which settings work for your style of video.
A computer is also useful for the unglamorous parts of exporting: checking available storage, archiving finished projects, and keeping a backup of the final file. If you edit on an emulator, remember that export still happens through the phone app’s pipeline, and the file you check is the one the app produced. Review it on the largest screen you have before you post, and treat that review as a required step, not an optional extra.
Frequently asked questions
What resolution should I export at?
Usually 1080p, matching your source footage. Use 720p only for small drafts, and 4K only when your footage was recorded at 4K and you want to keep that detail.
Why does my video look blurry after posting?
Check the exported file first, then your export quality and resolution. Low quality settings, upscaling low-resolution footage, and platform recompression are the usual causes.
Does exporting at 4K improve 1080p footage?
No. It creates a larger file without adding detail that was never captured, and can slightly soften the picture through upscaling.
How can I reduce file size without ruining quality?
Trim dead air first, then reduce quality one step at a time and re-check. Shortening the video usually saves more size than crushing quality.
Why did my export fail?
Free up storage, close other apps, and try again with the same settings. Repeated failures at high settings may mean you need one step lower.
Should I check the exported file or just the preview?
Always check the exported file itself, in full, with sound on and off. Previews can hide problems that the final file reveals.
