The spec, in X’s words
| What | Figure | Their words |
|---|---|---|
| Shapes it takes | From 1:3 to 3:1 | Aspect ratio : must be between 1:3 and 3:1 X |
| Picture size | 1280 × 720, recommended | Video Resolution : 1280x720 (landscape), 720x1280 (portrait), 720x720 (square). X |
| Shortest | 0.5 s | Duration : must be at least 0.5 seconds X |
| Longest | 20 min | 20 minutes by default for Post video X |
| Longer, for some | Up to 2 h 5 min with Premium | 125 minutes for Premium / verified Post video X |
| Largest file | 8 GB | 8 GB default for Post video X |
X states these limits on its developer pages, which say the caps on a posted video match the app’s.
20 minutes, or longer with Premium
X takes any shape from 1:3 – 3:1, so a vertical, square or wide video goes up as filmed; the button keeps it and checks the length. A posted video can run 20 minutes, and 2 hours 5 minutes for Premium or verified accounts.
X recommends 1280 × 720 for a wide video and 720 × 1280 for an upright one, and says subscribers get 1080p playback for a 1080p upload. Shycut keeps your video’s own size, so a 1080p phone video stays 1080p.
What the button sets up
- Your video’s own shape
- X takes anything from 1:3 to 3:1, so a phone or camera video stays as filmed; one outside that is cut to the closest shape that fits.
- Its length, checked as you trim
- The Size tab says whether your edit is a length it takes: at least 0.5 s and up to 20 min (Up to 2 h 5 min with Premium). The save window says it again before anything is made.
- No size limit set
- 8 GB is more than a video from Shycut comes to, so the size field is left empty.
- On your device
- The video opens in this browser tab and is made there. Nothing is uploaded, so there is no size limit on the original.
