Hey today I used video pad for the first time and it was also the first time I've ever edited a video. I began with a mp4 file that was 490mb, then I just did very simple stuff such as making two sequences to cut out like 3 minutes of video. The final exported video took hours and is 1.75gb. So 2 questions 1. Is it normal to make small edits and have the size of file jump from 0.5gb to 1.75gb? 2. Could you explain why? Any reply is welcome and thanks for reading
