I wish to report 2 separate erros.
1st error - If I upload the untouched avi file to YouTube it would give an error saying file type not supported so I had to render it in Adobe Premiere Pro CS6 in H.264 first before uploading.
2nd error - If I record voice with video(gaming or desktop) Multichannel audio can't seem to be detected in Adobe Premiere Pro CS6. It only reads the default sound and not the mic recording.
However, the voice recording is there when I play the untouched avi Action! file.
Please fix.
