I'm being tasked with uploading a video to an aggregator. They want ProRes 422HQ, and stereo and surround as separate audio streams (each 16-bit 48Khz LPCM, naturally). Is it possible to export a file like this via Compressor? Or take the silent video file, two WAV audio streams and combine them into one file somehow? The site does not give any tips on how to achieve this. They accept MOV, MKV, MPG, and OGG containers. No MXF, weirdly. There is only one upload conduit for the video and no other upload areas for individual audio files, etc.
