Hi there, everyone! I just found this site, and decided to join! I believe I'll be able to get my questions answered here. Well, I'm a YouTuber and I record videos daily. I own a Sony HDR CX-405 Camcorder. It allows me to record in HD 50p. I've recently started doing that. I've set my Sony cam to XAVC S HD - but I have some questions.. I use Movavi as my video editor, and it seems fine for what I need it for. When I record with my Sony cam, in HD 50p, the file I import to Movavi is MP4. I then edit the file for what I need, and then I export it. In the export menu I have several options.. MP4 with H.264 Codec MP4 with MPEG-4 Codec. What format should I choose? And what's the difference between the two? Thanks, everyone! Cheers!
