I was doing some tests here for "almost live" broadcasts to my whatsapp group. I record from a C920 and external mic using OBS to mp4 files x264. I´m using CBR and 1000kbps as bandwidth. The files are small 720p for 1 minute ( Around 20Mb ) but could be better. Perhaps there may have some good settings that I could for example have a 3 minutes long video with good quality, resolution and around 10Mbytes size. Are there ?
