AUDIO AND VIDEO OUT OF SYNC: I use the Windows 20.0.1 software with a Blackmagic Design Web Presenter, and do not stream with it but record its output to a Solid State Drive for editing, using the x264 encoder to create a QuickTime.Mov file. I have a PC with 12 GB of RAM, a GeForce 940MX GPU, and OBS says the CPU load is about 35% with the settings I now use. I run just a few other processes in the background while recording, but nothing that is also trying to use the SSD. I know the Web Presenter will vary its framerate, but am very frustrated because in many places, I find the audio and video drift out of sync, where it seems either the video or audio get ahead of one another, and I have to do a lot of editing of the audio to salvage the recording.
I don't know whether OBS or the Web Presenter is at fault, or if hardware and software settings are incorrect. Should I be using Constant Bit Rate, instead of Variable Bit Rate? I intend to soon use a pair of BMD Intensity Shuttle to ensure I always get 29.97 fps, but until that time, I need to have rock-solid sync between the video and audio being created.
