/vt/ - Virtual Youtubers

question to the smart video/audio anons here. if I wanted to export a video project with audio, what would be a good file type to choose? highlighted one is what the program suggested, but from my brief googling it seems mp4 (h.265) and webm (vp9) are the higher-quality ones
it's an edit of the watchalong, matching the audio of the live to the video the girls had. should be near perfectly synced if I did it right
