No, there are no limits to the size of your input file.
In the Clipchamp video editor, the conversion and compression process happens directly in your browser on your computer. Clipchamp does not upload your file to a cloud-based server for processing. This is why there is no restriction on the size of your input file.
Resolving problems when adding large files
Some users may encounter problems when adding large files to the Clipchamp video editor. This depends on:
size of the video

memory power of computer
storage of computer
the processing power of a computer
If this happens, we suggest compressing the files before adding them to Clipchamp. Users can try the HandBrake compressor.
