Making TikTok videos for an app?
An AI influencer reacts, then your screen recording plays, in 9:16 for TikTok. Your first video takes about 4 minutes.
A 9:16 vertical video at 23 to 60 fps, between 360 and 4096 px per side. TikTok for Business adds two more numbers: shoot at 720p or more, and keep the bitrate at 516 kbps or higher.
TikTok names no single best size. Export at 1080 × 1920, which is Full HD in 9:16. It clears every number here.
1080 × 1920, 30 fps, MP4, H.264
Every part of it sits inside a limit TikTok publishes.

TikTok processes every upload again before it goes live. It cannot add detail the file never had, so most blur starts in the file.
A 720 × 1280 video on a Full HD phone is stretched to fit. Scaling it up later adds no detail. Export from the source at 1080 × 1920.
Bitrate is how much data each second gets. Too little and motion turns blocky before TikTok touches it. TikTok lists 516 kbps as the floor, and most editors export far above it.
A 16:9 or square video is shrunk to fit a vertical screen, with bars around it. The picture uses a fraction of the pixels, so it looks soft even at 1080p.
Each export or chat app forward compresses the video again. Upload the first export from your editor, not a copy that was sent around.
TikTok takes 23 to 60 fps. A 120 fps slow motion clip or a 15 fps screen capture falls outside it. Export at 30 or 60.
Many accounts see a high quality upload switch on the post screen, under More options. TikTok's help centre has no page on it, so look at your own post screen before you post.
Use the final export, not the project. A phone recording works too. Rotation is read from the file, so a vertical clip shows as vertical.
Resolution, frame rate, bitrate and length. These decide how the video looks before TikTok processes it.
Fail breaks a limit TikTok states, such as 23 to 60 fps. Check is advice, such as 9:16 or 720p and up.
Change the setting in your editor, not in a converter. Then run the new export through the checker once more.
A sharp video can still hide its text under the caption and buttons.

A 9:16 vertical video between 360 and 4096 px per side, at 23 to 60 fps. TikTok for Business says to shoot at 720p or more and lists 516 kbps as the lowest bitrate. A 1080 x 1920 MP4 with H.264 clears all of it.
Export at 1080 x 1920. TikTok names no single best size. It accepts 360 to 4096 px per side and advises 720p or more. 1080 x 1920 is Full HD in 9:16, so a phone shows it without stretching.
Drop the file into the checker above. It reads the frame rate from the file in about a second. TikTok takes 23 to 60 fps, so 24, 25, 30, 50 and 60 all pass.
The only number TikTok publishes is a floor: 516 kbps or more for promoted videos. It gives no target above that. The checker shows your video bitrate so you can compare exports.
Most often the file was small, low in bitrate or not 9:16 before it was uploaded. TikTok processes every upload again, and it cannot put back detail the file never had. Check the file first, then export at 1080 x 1920.
TikTok's help centre says you can record up to 10 minutes in the app and upload videos up to 60 minutes. Posting tools and promoted videos stop at 10 minutes.
No. The checker reads the file in your browser. The video never leaves your phone or computer.
