I'm under deadline, Handbrake audio problem

[jfharper]

I encoded out of premiere to pic video codec avi highest quality. Then into handbrake to mp4...smaller files are ok, but this larger project gives me some glitchy noises sometimes during the video. I was thinking of encoding the video and audio separate, then muxing them back, but I don't know how to do this, or if this is the solution...I have yamb and avimux and sound forge at hand...can someone offer a suggestion on what I can do? TIA

Is the audio fine in the exported AVI before you use handbrake ?

If so, you can try encoding it with another audio encoder e.g. lamexp, foobar2k, audacity etc... , then mux with yamb

Alternatively, just use another front end e.g. ripbot, megui - they use a different AAC encoder

If th AVI audio not ok, you need to trace your steps back in premiere to determine at which stage the problem occurs

[jfharper]

yes, it is fine in the avi.

btw thanks for quite reply

what format am I looking for to convert the wav into to mux in yamb

[aedipuss]

aac is most common for mp4. use lc-aac

[jfharper]

thanks...I'll go try that...I can always count on the awesome people at videohelp

You can also try increasing the audio bitrate , maybe you used something low and that is causing the "glitchy noises"?.

Handbrake uses FAAC for AAC - FAAC produced audio quality isn't as good as NeroAAC or Quicktime AAC , but if you use high enough bitrates it should be ok

[jfharper]

sorry...is lc-aac a codec I need to download somewhere or tool here on videohelp

[jfharper]

I see the bitrate at 160 in handbrake...looks like that's the highest, unless I'm missing something..that's what I used in the encode with the glitches.

[jfharper]

I'll try nero acc then mux in yamb

[jfharper]

Well, I used foobar2000 with the neroaac to convert the wav out of premiere...than used yamb to mux both the raw h264 I extracted from the handbrake encode that had the glitchy audio, and muxed the raw video and aac. I didn't hear any glitches, but the video and audio are supposed to be 10:18 (mms) but yamb muxes to 12:20 so the audio is off and the time duration is not correct either.

I'll go try another mp4 encoder I guess unless there is an easier solution someone could mention. I hate to try something drastically different because I like to get the process down and then stick to it to save issue...might be my only choice

[jfharper]

OK, I got something to work. I exported audio wav from premiere, converted to aac using foobar2000, then muxed using yamb...but I used the m4v (from handbrake) file for the video and not the extracted raw h264 I extracted earlier in yamb...everything is better, except there was one glitchy noise...I went back to find the time to see if it was in the wav and it did not glitch the second time through...so I think it is my player...I am using media player classis with the ffdshow thing on...I read somewhere this player is kind of glitchy...anyone know of a player that would be better that I could recommend to my client?

[jfharper]

maybe vlc...I'll try that.

[jfharper]

Nope, I was wrong...the glitchy sound appears at 2:21 and when repeated using vlc...it glitches again...maybe it is in the yamb mux or aac conversion...I'll check those

[jfharper]

not in aac converted audio...must be the yamb mux...I'll try the 2.0 beta or maybe try muxing avidemux...flying a bit blind here

Try muxing with https://www.videohelp.com/tools/My-MP4Box-GUI
YAMB can be a bit quirky for some people.
