Workflow Question #75

Closed DrWig closed 8 years ago

DrWig commented 8 years ago

Hi. I'm looking into adding Ambisonic Audio to video files, but I'm not quite clear of the workflow/tools.

Jump Inspector help suggests making an MKV from a MP4/MOV/MKV video with an Ambisonic Wave file added.

Spatial media tools (to add required meta data) only works on MP4 files (and not Wave or MKV files).

So, if I have an audio free .MOV video and 4-channel wave file containing Ambix Audio, what do I have to do to get them working correctly other than using FFMPEG to glue them together as per the Jump inspector help file.

Do I have to tag both the video and audio files BEFORE FFMPEGing them? Or do I really need to FFMPEG them to an MP4 and then use the spatial-media tools to give them the correct meta-data?

We've got plenty of videos with Ambisonic audio (up to 4th order) and it'd be great to be able to present them in this way.

cheers

Bruce

FFMPEGing to AAC and MP4, then tagging with the spatial-media tools, and then using jump inspector results in the same. The AmbiX to binaural conversion/decoding seems to be not working as well as it should.

I think I'm missing something here......

Hi @DrWig, I believe you've since figured most of this out :), but for any future confused readers, Bruce's aforementioned article is a great guide.

We've also added Jump Help articles for spatial audio, ambisonic audio production in REAPER, and more.

In addition, Jump Inspector now supports uncompressed 16-bit PCM audio in .mov files, which you can also inject with spatial media metadata and upload to YouTube; so we're no longer suggesting MKV/Vorbis as a preview container/format.
