Why do my edited mp4 files get larger when I save them?
« on: July 12, 2018, 07:21:56 PM »
I have been doing some simple editing and cropping on some mp4 files. I notice that the resulting saved file is larger than the original, even though I've removed some content from the original.

To get access to some of the filters, it appears you must change the video output choice. I have been using MPEG4 ASP (ff) encoder. Where am I going wrong? Other than the files growing size the program is working fine. I am using 2.7.1.

Thanks a lot.

Why? Unless you need compatibility to some extremely old hardware, you should use a modern codec like H.264 or HEVC (the latter does have compatibility issues with equipment which is not top-notch).

DivX is obsolete and massively inferior, resulting in much bigger file sizes if the source video was compressed with H.264.
