Technical requirements
- Duration:

- File container format:
Interclips accepts Videos in the Quicktime format (.mov), due to a better comptibility between Apple and Windows workstations. Most of the cutting software are able to produce mov-files. Otherwise you should get a Quicktime Pro license. Then your Quicktime Player can create videos in the .mov format.
