How to Upload High-Quality Video to TikTok, Reels and Shorts

Why your video looks worse after you post it

Your video looks worse because the platform plays its own smaller copy, and your export, the upload or your phone’s settings can make that copy look worse still. YouTube says it first processes a new upload in low quality so it finishes faster, and adds higher qualities once HD processing is done. Instagram and TikTok don’t publish how they compress video. Both offer a switch for higher-quality uploads, which suggests the default upload is smaller (our reading).

Seven things make a post look worse:

• A small or low-bitrate export. A 720p file, or one saved at a low bitrate, gives the app less detail to start from. Instagram’s creator FAQ tells creators to “upload the highest resolution possible”.
• The quality switch is off. TikTok and Instagram each have a setting for higher-quality uploads, covered step by step below. Instagram’s help page warns that these uploads can take longer.
• A weak connection. A high-quality file is a bigger file. YouTube’s app lets you choose Wi-Fi or mobile data for uploads. Our advice for all three apps: post over Wi-Fi.
• Data saving on the phone you watch on. Sometimes the upload is fine and the playback isn’t. YouTube’s Data saver option plays videos at lower picture quality so they start faster. Check your own viewing settings before you blame the upload.
• Re-uploading a saved copy. A video saved from TikTok or Instagram is that app’s compressed copy, and posting it again compresses it a second time. Some chat apps also send a smaller copy unless you send the video as a file (our note). Instagram’s FAQ adds that a third-party watermark may be affecting a reel’s reach.
• The wrong shape. Instagram takes reels from 1.91:1 to 9:16. A file in another shape gets scaled, cropped or padded, and each resize softens the picture (our judgment). YouTube asks you not to add black bars to the video yourself.
• A changed frame rate. YouTube says to upload at the frame rate you recorded. Converting 60 fps footage to 30, or 24 to 30, can make motion stutter (our judgment).

The aspect ratio calculator gives the exact width and height for 9:16 or any other shape before you export.

What each platform publishes about upload settings

YouTube publishes full upload settings. Instagram publishes minimums and a quality switch for reels, and detailed numbers only for ads. TikTok publishes an HD upload option, length limits and specs for apps that post through its API. Where a platform publishes nothing, the table says so.

Where the numbers come from. TikTok: its 2021 HD announcement, its camera tools page and its developer guide. Instagram: its reel size page, its Reels page and Meta’s Reels ad specs. YouTube: its encoding settings, Shorts upload page and file size limit.

One export that works on all three

Make one file and post it to all three. This is our recommendation, built from the pages above:

• Size: 9:16 at 1080 × 1920. That is the most TikTok’s HD uploads keep, it matches YouTube’s 1080p row, and it clears Instagram’s 720-pixel minimum. If your footage is sharper, 1440 × 2560 matches Meta’s ad spec and YouTube’s 1440p row.
• Codec: H.264 video in an MP4, with AAC audio. YouTube recommends it, Meta’s Reels ad specs name H.264 and AAC, and TikTok’s developer guide recommends MP4 and H.264.
• Frame rate: the rate you filmed, fixed. YouTube asks for the recorded rate and Meta’s ad specs ask for a fixed one. Instagram’s reel page asks for at least 30 fps, so if you film at 24 fps, test a reel first.
• Bitrate: at least 8 Mbps at 30 fps, or 12 Mbps at 60 fps. Those are YouTube’s 1080p numbers. Instagram and TikTok publish none for regular posts, so we use YouTube’s for all three.
• Sound: stereo AAC at 48 kHz. YouTube recommends 384 kbps for stereo, and Meta’s ad specs ask for at least 128 kbps. Even out the loudness first with the audio normalizer, since the apps re-encode sound too.
• Color: standard range (SDR). YouTube recommends BT.709 for SDR uploads. If your phone films HDR, we suggest an SDR export, because HDR clips can look different from one app to the next.
• Length: 3 minutes or less. That is the Shorts limit, and Instagram doesn’t recommend longer reels to people who don’t follow you.

Bigger files rarely help once you pass these numbers, because each app re-encodes what it gets (our judgment). If you crop to fit the shape, drop a frame into the Reels safe zone checker to see what the buttons will cover.

TikTok: turn on HD uploads

Turn on TikTok’s HD switch every time you post, and upload over Wi-Fi. TikTok announced it in December 2021 as “Upload HD”, which publishes in up to 1080p, first in select countries.

1. Record or upload your video and go on to the posting screen.
2. Tap More options.
3. Turn on the HD switch, which TikTok named Upload HD in 2021. The label may differ in your app version.
4. Post the video.

TikTok’s current support pages that we could check don’t describe this switch. Its name and place may differ by app version and country. If you can’t find it, update the app and look again on the posting screen.

TikTok’s camera tools page says uploaded videos can run up to 60 minutes, and videos recorded in the TikTok camera up to 10. If you post through a scheduling app, TikTok’s developer guide applies instead: files up to 4 GB, frame rates from 23 to 60 fps, and MP4 with H.264 recommended.

Instagram Reels: upload at highest quality

Turn on Upload at highest quality, which Instagram’s help page describes as a way to always upload reels at the highest quality. The page’s full text didn’t load for us, so these steps follow its indexed text, and menu names may differ by app version:

1. Go to your profile, bottom right.
2. Tap the menu, top right.
3. Under Your app and media, tap Media quality.
4. Turn on Upload at highest quality.

The same page says higher-quality reels may take longer to upload, and that reels should be at least 30 fps and 720 pixels, in a shape from 1.91:1 to 9:16. Instagram’s Reels page says you can record and edit reels up to 20 minutes, but reels over 3 minutes won’t be recommended to new audiences.

If you edit in Meta’s Edits app, open your project and tap the resolution at the top right to choose the resolution, frame rate and color before you export. Meta says Edits exports carry no added watermarks.

YouTube Shorts: upload, then wait for HD

YouTube has no quality switch for uploads, so the file you send and a little patience decide the result. On Android, YouTube’s upload page gives these steps:

1. Open the YouTube app and tap Create, then Video.
2. Pick your file and tap Next. A square or vertical video of 3 minutes or less uploads as a Short.
3. To upload over Wi-Fi only, tap your profile picture, then Settings, General, Uploads. Menus on iPhone may differ.

On a computer, YouTube’s Shorts page says to click Create in YouTube Studio, then Upload videos, and you can select up to 15 Shorts at once.

Then wait. YouTube shows a new upload in low quality first, and higher qualities such as 1080p and 4K take longer to process. A Short that looks soft in its first minutes may be fine once HD processing finishes.

Export settings in CapCut, Premiere, Resolve and Final Cut

Every editor hides the same few settings in a different place. This table points to them, from each maker’s own help pages. Pick the values from the export settings above.

Check that the frame size reads 1080 × 1920 before you export, because a preset built for landscape video can resize a vertical project. CapCut’s help adds that you can’t export 4K if every clip is 1080p or lower. Whatever you use, export once from the original footage, because exporting an export compresses it twice (our judgment).

Check the quality on your phone after posting

Check a new post on Wi-Fi, with data saving off, after the app has finished processing, and compare it with your own export. These steps are our checklist:

1. Give it a few minutes. On YouTube, wait until HD processing has finished.
2. Turn off data saving where you watch. In YouTube’s app, Video quality preferences lets you choose Higher picture quality for Wi-Fi and mobile networks.
3. Play your export, then the post, on the same phone. Pause on four spots: small text and captions, hair and skin, dark or plain backgrounds, and fast movement.
4. Look for the usual damage. Soft edges on text, blocks or bands in dark areas, and smearing in motion all mean the copy lost detail.
5. Watch on a second phone if you can. If it looks fine there, your own settings or connection were the problem.
6. If the post is clearly worse, find the cause above. Fix it and re-upload from your original export, never from a copy saved from the app.

Thin, high-contrast edges such as small caption text show compression first, so large, bold captions hold up better (our judgment). See video captions people can actually read for size and contrast.

Exporting from EditorOP

EditorOP exports your reel as a vertical 1080p MP4, sized for Reels, TikTok and Shorts. A separate “Download captions (.srt)” button saves the captions as their own file. Post that MP4 as it is, from the device you exported to, with each app’s quality switch on. See how the AI reel editor works.

Upload quality questions

These are the upload-quality questions people search for most on YouTube, by vidIQ’s estimates, with short answers.
