Without Premium, X accepts videos up to 140 seconds and 512 MB. Longer clips are rejected, and very high bitrate phone videos can go over the size even when they are short.
What this preset does
This preset keeps 140 seconds, from the start or from the point you set in Advanced, and makes sure the file is under 512 MB at up to 1080p.
Questions
- How long can a video on X be?
- 140 seconds for standard accounts. Premium subscribers can post much longer videos.
- Why do some guides list bigger limits?
- X's developer documentation lists longer limits than its help center. Okaysize uses the help center numbers, which work for every account.
- What resolution should I use?
- 1080p and below works for everyone; X's docs reserve higher quality uploads for subscribers.
