Frequently asked questions
- Can I merge videos with different resolutions?
- Yes. SnapOtter re-encodes the clips to match a common resolution and codec when they differ. The output will use consistent settings across all segments. Processing runs locally on your own server.
- Is there a limit on how many clips I can merge?
- There is no hard-coded limit on the number of clips. The practical limit depends on available disk space and processing power on your server. All files stay on your own infrastructure throughout the merge.
- Will there be gaps or glitches between clips?
- No. SnapOtter handles the concatenation to produce seamless transitions between clips. If codecs or settings differ, re-encoding ensures a smooth join. Everything processes locally on your server.
