I am working on a video project with two audio tracks, targeted at Flash application which will turn on/off L/R channels
L = English, R = Chinese(with English faded)
I havent seen this issue before but, when exporting in Premiere PC/MAC cs4-c6, Premiere always seems to MIX (probably 80%/20%) the two tracks when using AAC
So the resulting h264/AAC when played back has an audio mix on both L/R when you listen to just one:
L = English + low Chinese
R =Chinese +low English !!
I want the two channels seperate and clean like in my edit!!
If you swap to exporting AAC+1 or AAC+2 the tracks are seperate and clean. (but issues of compatability on playback devices)
I have worked around this by exporting the videos using a HIGH data rate MPEG2 setting, then using Handbrake.
The MPEG2 keeps the audio seperate (with no unwanted cross talk)
Handbrake IS enocding the video to h264/ACC WITHOUT cross talk.
Also better quality (content has large still areas/slide based so)
Also better file size vs quality a 50MB Handbrake file @ 350Kbps looks better than a 100MB file @ 500Kbps exported by Prem.
Can anyone else confirm this unwanted cross talk and possible work around?
I am seeing the same here. Can't explain it though.
Well I guess I am glad someone else can see this... I think its a fault in the MainConcpet encoder.
Seems to affect many versions of Prem and PC/MAC...
For me the MPEG2>>Handbrake has improve quality and lowered files size, just not sure about keyframes...
Handbrake uses the superior x264 encoder, so that's not surprising.
