Sorry for top-posting 🙏 My content is gaming content, and I record the gameplay in form of .lmp files.
When a command ( which isn't related to ffmpeg ) is given from a batch file, the gameplay starts being played back. During the playing back of the gameplay, the audio and video are encoded simulataenously. So, even if I wish, I can't use 2 pass encoding. So, which option from the 2 should I stick to ? CVBR or ABR ?
