Rendering Audio from software

Postby Kawatta-kun » Sat Dec 25, 2010 7:48 pm

Rendering from NLE, for vídeo we use UTVideo, what about for audio?
Before I thought of some sort of LAME ACM, was for audio? Anyway, it does not appear on my settings. The best I can do is rendering in PCM Uncompressed or MPEG3, being this last one of better qualitty IMO.

PCM Uncompressed is probably your best bet. Uncompressed audio isn't insanely huge (compared to video, anyway), and it's not a lossy compression like MP3 is.

The LAME ACM is for when you're making your distro copy and want to use MP3 audio, not for rendering your master NLE export. Plus it's mostly there for legacy reasons (Xvid/MP3 in AVI distro copies), because there are much better options for encoding your distro audio (AAC if you're making an MP4, or either AAC or FLAC if you're making an MKV).

There is also a plugin for premiere which allows it to import FLAC directly, so you don't even have to convert it to wav, assuming you have that at hand. :)

I actually think PCM Uncompressed has less quality than MPEG3, while listening attentively to it :'x
But I think another way is to render as WAV and then all at Zarx264gui, right?

@mirkosp. Interesting ^^ actually I don't used it much, yet, but will have that on mind.

So the lossless quality identical to the cd itself (assuming that's where the wav comes from) is worse than a lossy re-compression of it? :rofl:
It's not even a matter of taste, lossy compression is objectively worse in terms of quality. Which is why you should keep everything lossless until the final lossy compression for the distro, to not introduce generation loss.

You are a fucking moron. How can a source have less quality than a degraded copy of it?

So your ears suck, or you for some reason have one of VERY few sources where certain interference gets removed by lowpassing, which I really doubt. A lot.

I don't know if this helps, but generally I keep my music in FLAC. I convert a lossless PCM (.wav) copy for use in the NLE, and on export of the final video I choose uncompressed PCM matching the source format (I.E. if my source is 16 bit 44.1khz, that is what I use). This will guarantee as little loss as possible when the time comes to do the final encode, regardless of which format I choose (AAC, MP3, etc.)

Taking things a step further, I generally encode x264/FLAC/MKV. This means that after I have encoded the video, I simply mux the original lossless FLAC audio file with the video using MKVMerge. These days, the difference in filesize between lossy and lossless for this purpose (AMVs) is negligible in most cases.

If you people insist on making amvs, THIS is how they should be done.
