I could spot no obvious quality degradation and so this is now a standard part of my mac video production workflow.

This brought a 6 gig file down to 650 mb. I found the following code and comments on gist ffmpeg -i original.mp4 -vcodec h264 -acodec aac compressed.mp4 hc/en-us/articles/203727328-Camtasia-Mac-How-to-Make-the-File-Size-of-Videos-Smallerīut the time it takes to experiment with different settings didn’t seem worth it. But I needed this file on Vimeo to share with my Patreon group.Ĭamtasia recommend changing dimensions, frame rate and data rate. This doesn’t make that much difference to me usually since hard drive space is cheap, YouTube doesn’t care, online course hosts tend to reprocess your video and shrink it anyway. I’ve been using a Mac more and I’ve noticed that the mp4 files generated by Camtasia on the mac are much bigger than those generated on the PC.Ī recent conference talk recording was output at 5.74 gig which meant I couldn’t upload on my Vimeo plan so I had to find a way to compress the file.
