This works perfectly and premiere accepts the file with ease. Thank you for this info!</div><div><br></div><div>For those attempting similar things, I used FFMPEG to create a standalone m4v file with a h.264 stream (encoded to my liking) as well as a mov file containing just a PCM audio stream (mp4box would not accept a wav file for some reason). Mp4box accepted both of those with the syntax mentioned above and gave me a single mp4 file that premiere was happy with.</div><div><br></div><div>====</div><div><br></div><div>may be ffmbc also accepts this. If &#39;support&#39; was as simple as &#39;id case somewhere&#39; - we probably can patch our ffmpeg too</div>
