LINE's 5-Minute Video Cut-Off: Why Your Clip Arrives Chopped (and How to Fix It)
You sent a video on LINE and the recipient says it ends partway through? That is not a bug. LINE auto-cuts any video over 5 minutes when it is sent in chat, and you do not get to choose where the cut lands. The fix is simple: trim the video to 5 minutes yourself, in your browser, before you send it — so you decide which 5 minutes actually get delivered.
Check the length
Open the video and look at its duration. Anything over 5 minutes will be cut mid-clip by LINE. Decide which 5-minute window is the one you want the recipient to see.
Trim to 5 minutes with AVMint
Open AVMint Trim in your browser and drop the file. Set the in and out points to a 5-minute (or shorter) window. Copy-mode trimming keeps the original quality — no re-encoding, no quality loss.
Compress and send
Drop the trimmed clip into AVMint Compress, aim for a sensible size like 100MB or 250MB so the recipient is not crushed by mobile data, and send the result through LINE as a normal video message.
Tip
LINE Keep and albums are not the same as sending a normal inline chat video. If your original is long, trim or split it first. AVMint's copy-mode trim is instant and lossless, so you can cut a 30-minute clip into multiple 5-minute messages without re-encoding. If your LINE app exposes a file attachment flow, you can also send the original as a downloadable file instead of an inline video.
Why LINE cuts video at 5 minutes
LINE's chat video pipeline was built around short-form communication, and the 5-minute cut-off is enforced at the send step so every recipient — whether on a fast Wi-Fi connection or weak mobile data — gets the same consistent, bounded download. The trade-off is that long clips are silently truncated, not rejected, which is why so many people only discover the problem when the recipient tells them the video 'cuts off mid-sentence'. The reliable way out is to trim yourself first so you stay in control of where the cut happens.
Letting LINE cut vs trimming yourself first
| Trim yourself (AVMint) | Let LINE auto-cut | |
|---|---|---|
| Control over cut point | Full — you pick in/out | None — always first 5 min |
| Quality | Lossless copy-mode | LINE re-encode |
| Recipient sees your key moment | Yes | Only if it's in the first 5 min |
FAQ
How long can a video be when I send it on LINE?
5 minutes. Anything longer gets auto-cut by LINE when you send it in chat. Trim the clip yourself first with AVMint so you control exactly what the recipient sees.
Is there still a file size cap on LINE video messages?
LINE has relaxed its file size rules over time, so the 5-minute length cut-off is the rule that bites users today. That said, keep the file reasonable (around 100MB or 250MB) to be kind to the recipient's mobile data and to avoid LINE re-compressing it too hard on send.
Where does LINE make the cut on a video longer than 5 minutes?
LINE starts from the beginning and cuts at the 5-minute mark, so anything after 5:00 is simply gone for the recipient. If your important moment is at minute 7, you must trim yourself beforehand.
Is there a way to send a 10-minute video as one message?
Not as a normal inline video message. The realistic workaround is to trim into two 5-minute segments with AVMint Trim and send them back-to-back, use LINE's file attachment flow if available, or upload the original to a cloud link and share the URL.
