Perhaps try out a few short clips with different bitrates on export so you can see the difference in file size v picture/sound quality. Try another export and choose a similar bitrate in openshot to export with, to the bitrate of the zoom video, and see how that suits you. Skip to 5'40 in the video below, it shows you where the bitrate settings are in Openshot On export I choose to 'restrict' the bitrate to 7000 to 7500kbs to keep things about the same. It sounds like you just need to change/lower the export bitrate settings in Openshot to bring it down to a size you are happy with.įor example, I screen record in OBS at 6500 kbsĮditing in Davinci Resolve, I could choose 'Best' or 'Good' preset for export which will produce a massive file size with no improvement to quality, as the original video was only at 6500kbs so no point in exporting at say, 15000kbs What are the bitrates you find on both videos?

Right click the OpenShot video export and do the same. Right click/properties the zoom video file, choose the 'details' tab and note the bit rate. Every time I export the video using Openshot, it comes out about at about 300mb.
