Question / Help Version 0.14.2 - AAC Audio Encoder

[Hieu Tran]

My friend and I want to record some gameplay for YouTube. We're using OBS Studio version 0.14.2. When he records, he uses the NVENC H.264 video encoder and we're both unsure about the audio encoder. When we put the .mp4 file into Sony Vegas Pro 11, there is no audio track for it.

At this point, I'm 100% sure that it's because it's using an MP3 encoder rather than an AAC encoder but I'm not too familiar with audio encoding as it is to figure this out on my own. Is there a way to change this with OBS Studio 0.14.2 or check to see what encoder we're using?

I'm 100% sure you're wrong. You have to go massively out of the way to get studio to use anything other than AAC for the audio track.

OBS-Studio by default uses FFMpeg AAC or Media Foundation AAC depending on your bitrate and unless you installed CoreAudio:

You can also check your recorded video with "MediaInfo" to see in which format the audio track is saved. But unless you use OBS-Classic or the Custom FFMPEG Output in OBS-Studio, there is no MP3 encoder available.

Unfortunately it is possible that Vegas has a problem with the written audio track and does not detect it correctly. An option would be to extract the audio track with ffmpeg for example and load it directly into Vegas to see if that works fine.
