Video checker for Reels, TikTok and Shorts

Drop a video. The checker reads its file type, codecs, picture size, frame rate, bitrates and length, and compares each one with what Instagram Reels, TikTok and YouTube Shorts publish. When a value misses, it tells you why and how to fix it. The video stays on your device.

How to check a video for Reels, TikTok and Shorts

  1. Add your video

    Drop a video in the box above, or choose the file. MP4, MOV and WebM videos work in most browsers.

  2. Read the checks

    The checker lists what it read from the file. Below, each app has its own list. A green mark fits. A red mark misses a limit the app publishes. A yellow mark fits but misses what the app recommends. Each list links to the help pages the numbers come from.

  3. Fix what misses

    When the file type, codec, size, frame rate or bitrate misses, press Make an MP4 that fits. The tool writes an H.264 MP4 with AAC sound and checks the new file. When the shape, length or file size misses, the row links to the free tool that fixes it.

Frequently asked questions

Is my video uploaded?

No. The checker reads the video in your browser. Nothing is sent to Vidova or anywhere else.

What does Instagram ask for?

Instagram Help says Reels should have a frame rate of at least 30 fps and a resolution of at least 720 pixels, with an aspect ratio between 1.91:1 and 9:16. Reels can be up to 20 minutes long, and Reels over 3 minutes are not recommended to new audiences. Meta's developer docs add MOV or MP4, H.264 or HEVC video, AAC sound at up to 48 kHz, 23 to 60 fps, at most 1920 pixels wide, at most 25 Mbps and at most 300 MB, and recommend 9:16.

What does TikTok ask for?

TikTok's help center says uploads in TikTok Studio must be MP4 or WebM, 720 × 1280 or higher, up to 30 minutes long and less than 10 GB. TikTok's developer docs give 23 to 60 fps, at most 4096 pixels on each side, and H.264, H.265, VP8 or VP9 video, with H.264 recommended. TikTok publishes no bitrate, so the checker does not check one.

What does YouTube ask for?

YouTube makes an upload a Short when it is square or vertical and up to 3 minutes long, and YouTube Help says you can upload Shorts at up to 1080p. For uploads, YouTube recommends MP4, H.264, AAC or Opus sound at 384 kbps in stereo, the frame rate you filmed at, and a video bitrate of 8 Mbps for 1080p at 24 to 30 fps or 12 Mbps at 48 to 60 fps.

What does Make an MP4 that fits do?

It writes the video again as H.264 in an MP4 file, at a constant frame rate. It scales the picture down when it is larger than 1080p or wider than 1920 pixels, brings a frame rate above 60 fps down to 60, and uses the bitrate YouTube recommends for the new size and frame rate. Below 720p, where YouTube gives no bitrate, it keeps the bitrate of your video. AAC sound is kept as it is. Other sound becomes AAC at 128 kbps, the bitrate Meta gives for Reels, in mono or stereo at up to 48 kHz. It never scales a video up. Then it checks the new file.

Why can it not fix a low bitrate?

Detail that the file lost when it was compressed does not come back when you encode it again. Export again from the original footage or from your editor at the bitrate the app recommends.

How does it read the bitrate?

It adds up the size of every video and sound packet in the file and divides by the length. That is the average bitrate. Short parts of the video can use more or less.
