On the input side, our video converter and video compressor supports a wide variety of different video formats, e.g. AVI, MOV, DIVX, FLV, 3GP, MP4, MPEG, WMV, VOB, DCM and MKV. If you’re not sure if your input file is supported, select it and see if Clipchamp is able to recognize it as a video file.
Regarding output video that Clipchamp produces, when you choose any preset other than the Windows/Microsoft Office one, the resulting output video is an MP4 container, using the H.264 video codec and AAC audio codec, or a WebM container using VP8 and OGG, which have all emerged as the de-facto standards on all modern devices (smartphones, tablets, laptops, desktops, gaming consoles, Smart TVs, etc.) and on the web.
When you choose one of the Windows/Microsoft Office presets, the output video is an ASF container, using the WMV video codec and WMA audio codec. This works on all operating systems including Windows, Mac OS and Linux.
If you're seeing an error message that your input file is not supported, this can mean that it's not a video file, that your video is corrupted or in a format that Clipchamp doesn't recognise.
One option to try in such a case is to reload Clipchamp following these suggestions - https://help.clipchamp.com/hc/en-us/articles/204606507-What-to-do-if-Clipchamp-doesn-t-work-.
Unfortunately however, there are some input files that cannot be processed with Clipchamp.
