Duration problems
Video too long for the platform? Limits and how to cut it
Short answer
Every platform sets a maximum length: X allows 140 seconds for non-Premium accounts, LinkedIn 15 minutes, Pinterest Pins 4 seconds to 5 minutes (video ads up to 15), and YouTube 15 minutes until you verify your account. Trim the file below the limit, split it into parts, or raise the account's limit where the platform allows it. Check duration with ffprobe before uploading, because editors and phones round differently.
Key takeaways
- X: 140 seconds for non-Premium; LinkedIn: 15 minutes; Pinterest Pins: 4 seconds to 5 minutes (ads up to 15); YouTube: 15 minutes by default.
- YouTube lets verified accounts upload videos longer than 15 minutes.
- Split long videos at natural breaks instead of cutting mid-sentence.
- Check the exact duration: a 140.0 second clip can show as 2:20 in one tool and 2:21 in another.
Published limits at a glance
From each platform's own help page, read on 2026-10-06. Limits can differ by account type, so check the composer when a file sits near the edge.

|---|---|---|---|
| X (non-Premium) | 512 MB | Up to 140 seconds | Prompts you if the format is not supported |

| 5 GB | 15 minutes | MP4, MOV, AVI, WEBM, MKV, WMV and more; 256 × 144 to 4096 × 2304; 10 to 60 fps; 192 kbps to 30 Mbps | |
| Pinterest (organic Pins) | No video size stated | 4 seconds to 5 minutes | Web: MP4, M4V; Android and iOS: MP4, MOV, M4V; H.264 or H.265 |
| Pinterest (video ads) | 2 GB | 4 seconds to 15 minutes | MP4, MOV or M4V; H.264 or H.265 |

Find your case
| What you see | What it usually means | Do this |
|---|---|---|
| Rejected on X for length | Over 140 seconds on a non-Premium account | Trim or split (steps 1 and 2) |
| YouTube will not take it | Over 15 minutes on an unverified account | Verify the Google Account (step 4) |
| Pinterest refuses a very short clip | Minimum is 4 seconds | Extend or loop the clip |
| Looks short enough but still fails | Duration rounding or an audio track longer than the video | Check with ffprobe (step 3) |
Fix it step by step
Trim
Cut the start and end first; many clips have seconds of dead air. Re-encode only if you need exact cuts.
Split into parts
ffmpeg -i in.mp4 -c copy -f segment -segment_time 120 -reset_timestamps 1 part_%03d.mp4writes 120 second parts without re-encoding, cutting at the nearest keyframe.Confirm the real duration
ffprobe -v error -show_entries format=duration -of default=nw=1:nk=1 file.mp4prints the duration in seconds. Compare it against the limit with a few seconds of margin.Raise the limit where possible
YouTube says you can upload videos up to 15 minutes by default and that verified accounts can upload longer ones. X Premium subscribers can upload videos shorter than 4 hours.
Speed up as a last resort
A modest speed-up shortens a talking video but changes pitch and feel; use it only if cutting content is not an option.
Split points that work
- Cut at the end of a sentence or a scene change, not at an exact minute mark.
- Number the parts in the filename so they upload in order.
- Repeat a short recap at the start of part two so viewers who land there are not lost.
