Hi Adobe family,
I'm hoping someone can help me with this it's been driving me nuts. I have been asked to supply a video to a Media agency for compliance checks before it can go live. They have requested the below specs
Resolution (SD format): 720 x 576
Aspect ratio 16:9 PAL
Frame rate 50 field/s, 25 frame/s
file size: Under 10mb
Original Format PCM audio (not including Dolby E or AC-3)
Sampling rate 48kHz
Stereo Lt Rt
Where Dolby Digital (DD) derived mixed down Rt Lt
My source file is a 1920x1080 HD file with PCM audio. The whole project length is 28 seconds, and I'm exporting from After effect because I had to do some title changes and a few other tweaks etc.
Firstly is there even a way to encode a .mp4 with PCM audio direct from media encoder? Or are these guys just smoking the fun stuff? Because if there is a way I for the life of me cannot find how to make this work with the h.264 codec direct from AME. Secondly to get below a 10mb file surely there is no way of doing this even if I was able to include uncompressed audio or am I missing something.
I would LOVE someone that has used AME extensively or by some miracle someone from Australia who has had to request CAD approval for a TVC who can help with these settings.
Thank you to everyone in advance who might offer help
PCM is not a supported audio codec in MP4 containers. Some vendors violate this; for example Sony puts PCM in the MP4's geneated by their A7s camera. You can use a MOV container though.
As for getting AE to generate PCM, I've never tried it myself. If it doesnt support it can you always mux it in using ffmpeg.
