I'm working on video editing on VSDC and my exports are so much larger then the original video when I export it into mp4 format. All I did to the video was delete the sound from the video and replace it with the same sound which I cleaned up a bit with audacity and exported into wav format. The original size of the video was 34mb and the wav file was about 4mb but the export was over 200mb. I exported it with the option that the software has for youtube and set the quality for 1080p. I don't understand whats going on. Could it be that my original video is of a lesser quality then 1080? And the software is adding filler pixels? Are these the numbers I should be looking at? the original file was mov.
I got a more reasonable file size of 31mb when I exported to avi. Even exporting to mkv its only 41mb.
