Convert MOV to MP4 for easier sharing
A MOV recorded on an iPhone may not open in the recipient's software. An MP4 copy can help with compatibility, but renaming the file extension does not convert the video.
Open tool →Steps
- Select videos in ClipForge and choose local or server conversion.
- Match the container, codec, resolution and video and audio settings to the destination.
- Check a short trial for sound and picture, then save the result.
File selection screen
Prepare a copy for its destination
Check which codecs the destination accepts as well as the file extension. MP4 is not automatically smaller. First make a playable copy, then adjust resolution or duration if size is still a problem.
Settings and checks
Select the MOV file. Choose MP4 and a target resolution.
Where processing happens and device limits
Local conversion does not send files to the conversion server. Choosing server conversion uploads them. Local conversion supports up to 512MB; server conversion supports a combined selection up to 64GB. Memory and input codec support can cause failures even below these limits.
Troubleshooting
If playback fails, check the codec inside the MP4 container too. If size exceeds the limit, review bitrate, resolution and duration. After changing fps, inspect motion, synchronization and playback through to the end.
Frequently asked questions
Is specifying only target size or resolution enough?
No. Bitrate, duration, fps and codec affect size and quality even at the same resolution. Include audio in the size budget and inspect the exported size and playback.
