TikTok Video Dimensions and Aspect Ratio
For a vertical TikTok video, 1080 x 1920 pixels with a 9:16 aspect ratio is a practical editing preset. Export an MP4 with H.264 video and AAC audio, then check the preview in the upload screen before posting.
These settings are a starting point for an editing project. Your source footage, chosen layout, and upload controls determine the final result.
- Vertical video uses a 9:16 canvas. A 1080 x 1920 project gives you a full-HD vertical export.
- Square video uses a 1:1 canvas, such as 1080 x 1080.
- Landscape video uses a 16:9 canvas, such as 1920 x 1080.
Choose the layout before adding captions and graphics. Keep important text away from the edges and check its position against TikTok's on-screen controls in the posting preview.
Export Settings for a Vertical Video
Use the following starting settings in your video editor, then play the exported file before uploading.
- Set the canvas to 1080 x 1920 for a vertical project.
- Choose MP4 with H.264 video and AAC audio when your editor offers those options.
- Keep the source frame rate when it suits the project. 30 fps is a practical choice for a new tutorial recorded at 30 fps.
- Try a video bitrate of 5-10 Mbps for a 1080p export, then inspect moving details, text, and gradients.
- Export from your editing project and retain the original recording for future edits.
A higher bitrate makes a larger file. Compare a short section at your chosen settings before exporting a long video, especially when the footage contains fast movement or fine text.
Estimate TikTok Video File Size
A useful estimate in decimal megabytes is total bitrate in Mbps x duration in seconds / 8. Include the audio bitrate in the total. Variable-bitrate encoding and container overhead can change the final file size.
For example, 60 seconds at 8 Mbps video plus 128 kbps audio is approximately 61 MB. At those same settings, a 30-second clip is approximately 30.5 MB. Check the exported file's actual size before uploading.
For the applicable upload limit, read the message or requirements shown in the TikTok app or web uploader you are using. If it rejects the file, note the displayed limit, shorten the clip or lower the export bitrate, and retry with the new file.
Current TikTok Video Duration Guidance
TikTok's Camera tools help page states that videos recorded in the app can be up to 10 minutes, and uploaded videos can be up to 60 minutes. It also says that selecting a sound before recording or uploading makes the video length depend on that sound's length. This guidance was checked on November 13, 2026. TikTok Camera tools
When recording, select an available duration above the Record button. When uploading an existing file, check the available editing and trim controls before posting.
Check a Downloaded TikTok Video's Quality
Use the VidQuark TikTok Downloader to request an available MP4 from a public video link. Choose an available quality option when the result card offers one. Results depend on the source video and the formats returned for that request.
After downloading, open the file in a player or video editor and inspect its file information.
- Check the width and height to identify the downloaded resolution.
- Check the frame rate if you plan to edit or combine it with another clip.
- Play the entire file to confirm that the picture and sound continue to the end.
- Compare it at the same display size with the source if you are investigating a quality difference.
Keep your original recording or editing export when you need a master file for later work. For finding a saved MP4, follow the iPhone file guide or Android Downloads guide.
Fix Cropping, Blur and Large Files
The Video Is Cropped in the Preview
Check the editing canvas and the source clip's aspect ratio. Reposition the clip or add background padding to fit the chosen layout. Review captions, faces, and important details in TikTok's posting preview.
The Export Looks Blurry
Play the local exported file first. If it is already blurry, check the source resolution, scaling, focus, and export bitrate in the editor. If the local file looks clear, compare it with the posted version after the upload has finished processing.
The File Is Too Large to Upload
Use the current uploader's displayed requirements. Reduce the bitrate, shorten the video, or make another export using a compatible format. Check the new file's size and playback before uploading again.
A Download Fails or Stops Early
Check the error shown by the downloader and confirm that the source video still opens. Copy a fresh link and retry after any indicated waiting period. The download troubleshooting guide covers link, connection, and request-limit problems.
