Why does my video file grow ever larger when I trim it?

Mark-Anderson wrote on 4/16/2020, 2:37 PM

My video files start as mp4 and saved as mp4 but apparently I'm doing something to greatly enlarge the final mp4 file and I don't know what it is. Can someone please guide me in the way to approximately preserve the size of the file after minimal editing? Thanks. Mark A.

Hi Mark and welcome to the Movie Edit Pro user forums.

A file size can be influenced by what you add to it. Adding complexity to the finished file could add extra data to each frame such as altering the colour or sharpness. If you pick a higher quality export to try to emulate the original files perceived quality, that will also increase file size. If you can get a free download program called Mediainfo and then cut and paste the info from the exported file and one from one of the clips you are using, we may be able to make some suggestions. When using Mediainfo (once installed you only have to right click a video file and select mediainfo from the dropdown list) Use the 'Tree View' or 'Text view' to see all the files coding information.

The blue Mediainfo word above is a direct link to the download site.

Thanks very much. I downloaded Mediainfo and will learn to use it. I wonder if there is a setting in Move Edit Pro to keep the new exported video file within the same parameter settings as the original imported video.

Hi Mark.

No it doesn't have any such setting.

Although any editing in most video editing programs don't alter the original clips, once edited, the files have to be re-rendered to come out as one new video or you would end up exporting several short clips not joined together. This means it has to be re-encoded as well, making like for like transfers impossible.
