Need export setting with uncompressed audio that doesn't generate gargantuan file

Community Beginner ,

Hi all,

I have been going through the forums and don't see an answer to this.  I am exporting live recordings of orchestral concerts with some videos added.  My recording engineer is adamant that we export using uncompressed audio (so not AAC).  I have been experimenting with different formats, but so far all have generated 3-5 gigabyte files for a 4 minute video.  

 

For the audio, here are his requested settings:

uncompressed

44.100 kHz

24 

 

There are no requirements for video.  However, it would be nice if it would playback on my computer after exporting.

 

Thanks in advance for the input,

 

Anne

Look at a lower bitrate version of some of those intraframe codecs, something like Quicktime ProRes LT or Proxy.

Here is a codec comparison chart if you want to... compare various codecs: https://blog.frame.io/2017/02/13/50-intermediate-codecs-compared/

Thanks!  Your article was very helpful.  I tried ProResLT and ended up with a green screen.

 

Howver, GoPro Cineform YUV with a low quality (1 worked fine) ended up working really well for me.  

 

My only remaining issue is that I also have to submit the same videos to Facebook and it's not liking any of the formats.  I may end up giving up and going with AAC for those.

The DNx variants all actually work on YouTube, as another option.

Thanks.  Any idea what might work on Facebook?  I did run a sound comparison between the uncompressed and AAC (and AAC+2) and the uncompressed did sound better.

Nope. Give it a try. Testing is a pretty normal part of editing.

I don't upload directly to FB very often, so I can't speak with much experience there, but FB tends to compress things big time (more than even YT), and it wouldn't surprise me that they wouldn't let people upload uncompressed codecs. And even when you do upload an uncompressed codec, they are going to compress it. You are unfortunately always going to be limited by deliverable specs and resulting compression of your end platform (YT, FB, etc.) Your recording engineer may be an experienced audiophile, but short of you sending an uncompressed file to each person who is watching/listening to your videos, there's probably going to be some concessions that need to be made based on the platforms these end up on.

Fair enough.  I think he's aware that it will be compressed by the platform so he's trying not to add any addiitonal compression.  As someone said, it's going to be a question of trial and error, and also running by some different people who might not have as experienced ears as my recording guy.  There's a tradeoff between getting it perfect and getting the material out to as many people as possible.
