Editing video with Photoshop premiere Elements (1 Viewer)

[Baron Birder]

I have just started learning this and have a question. A friend asked my to clip off the first minute of his mp4 video which I did easily. The original file was 216mb. I wanted to save the edited video as mp4 and used the share and export feature. However the software said the resulting file would be over 1gb even at the lowest resolution.
Can anyone explain why this is, or what I can do? I would like the final file to be roughly the same size as the original
Thanks

Video is minefield of formats. Comparing two files can be a nightmare. There are different frame rates, different bit rates and different who-knows-whats to consider. I can't speak for Premiere Elements as I don't know the software but Windows 10 will trim videos in the Photos app (I know it is stupid that Photos is the app to edit video). If the final version is still too big then Handbrake is a good free program to tweak the video parameters to get the file size down.
