Clipchamp video editor file size is 5 times larger than LosslessCut

Ken Smith 105 Reputation points

When I simply concatenate 4 mp4 files, whose total individual size is roughly 13 MB, I get a 13-14MB file with LosslessCut but I get a 67MB file with Clipchamp. Nothing other than concatenation is performed. I really like the ease of use of Clipchamp (if I wanted to edit the clips) but I would like a smaller file size without loss of quality. Am I doing something wrong when I concatenate mp4 files with Clipchamp?

    I wouldn't say you are doing something wrong. Clipchamp is really bad at recompressing files. Most mp4 are compressed to some extent, and to edit them they get transformed by the software and then repackaged. Some software is better at this, Clipchamp just isn't one of them. You can keep an eye on the output settings, but it's likely that either some of the compressed data does not get compressed back or that Clipchamp adds data to the file while processing it. It's a very common thing to happen, but still do try to check those output settings to make sure you are not unnecessarily selecting for a bigger output than you intend.
