Efficient codec with multitrack audio?

[spencergrant]

Hiya!

I'm trying to export a file with multitrack audio. I'm used to exporting all of my videos in h.264 or h.265, but they don't support multitrack for some reason, so now I'm stuck. My other options look like ProRes or Quicktime, but the filesizes on both of those are gargantuan compared to h.265 and I don't especially care about the image quality (The videos will be uploaded to YouTube later on at 1080p60. There is another step in the interim period that requires both the video and the audio to be baked together and for the audio to be multitrack).

Are there any other codecs comparable to h.265 that support multitrack natively? Is there a Quicktime codec I can use that won't fill my hard drive up?

Thank you in advance.

Prores, h.264, and h.265 are codecs. Quicktime and MP4 are containers.

You can export h.264 in a Quicktime container. You won't get as much compression as h.265 but if you don't care about video quality, knock the bitrate down to 2mbps and you'll get a small file.
