Export from Premiere pro to x264 - help needed

[flatterbe]

Hi guys,

I have a movie in Premiere Pro (CS6) and want to export this to a compliant MP4 (h.264 - aac).

Normally I render first to a lossless format (lagarith or Ut Video Codec) and afterwards I render this to MP4 by using Handbrake.
I'd like to skip the lossless codec step because of the very huge files.

By using x264vfw I can export the video directly but the audio will be encoded as PCM.
No problem (I thought :-), I just export the video by using x264vfw and export the audiostream as AAC.

So far so good. However, when I try to mux the video and audio to MP4, I get 'Bitstream not compliant' and nothing is muxed.

My questions:

1) How can I encode a valid h.264 stream by using x264vfw in Premiere to mux with the (aac) audiostream afterwards?

OR

2) Is it possible to encode the audio directly to FAAC when using the x264vfw codec? I know there is an (expensive) codec x264pro which does the trick. Any other free tools available to get this done?

I'm really stuck here.
Somebody can help me out?

Regards.

What are you using to mux? ffmpeg or mp4box should work.

Have you tried a frameserver like debugmode? This will make a little virtual AVI you can feed into downstream apps like avisynth or handbrake.
