In the meantime, someone who needs multi-channel H264 can export to multi-channel QuickTime ProRes and then convert that to H264 in the Finder via "Encode Selected Videos". That said, maybe the Premiere Pro team could come up with a way to support H264 via AV Foundation Frameworks (Mac Only) or some other method that allows for going out-of-spec for MP4 or working around it via MOV. QuickTime as s system driver for time-based media going away sidelinesd a lot of workflows.Īs far as the MP4 wrapper goes, it only supports Mono, Stereo, or 5.1 (not multi-channel).
Multi-channel H264 was a result of legacy QuickTime, which Apple deprecated back in 2013 in favor of AV Foundation Frameworks. To verify use either MPEGstream clip or MediaInfo which is also free to verify the file codec is H.264 and the format is a MP4. once it finishes if all was done right you should have a H.264 multichannel file with a MP4 extension. Thats it drop it into the queue and start exporting. once the file is open check the preset tab it should say MP4 FileĬheck the video tab and the picture tabs to make sure al is okey dokey, open the audio tab and select tracks tab and import all tracks voila the tracks all appear in this case 4 now you do have to change sone settings to the right of each track, codec which should be set to AAC, mixdown set to mono, sample rate 48, bitrate whatever is required in my case 256. Open the file with Handbrake which is free, FREE no limited trial or other BS.
Once you export your file you should have a H.264 QT movie with however many channels in this case 4 Channels. when you are ready to export make sure to check VIDEO CODEC to H.264 your format can be Quicktme it won't matter for the conversion, just make sure your Video Codec is H.264 in the Audio tab assign your channels, again Im not going to explain this part. Okay here we go, you have a multi channel output lets just say 4 channels In PPro prep your file the best way you know how. So you have to export a file as H.264 QT with uncompressed audio to get all the channels. mp4, the only options are stereo, 5.1 or mono. As you know PPro cannot export H.264 files with Multichannel AAC audio as an. I needed to deliver a file in H.264 with AAC Audio multichannel as a mp4. HI All, Just wanted to chime in here Andre thank you for the post and I am glad you found a solution, just kinda wish you could share it with the rest of us.Īfter exhaustively reading the post and not getting any good answers, I got answers but always I was referred to purchase some type pf software or be a programmer and try to write script.We don't have time for all that we are under a deadline and Kudos to those who can, you're very smart.
