Hello Bret, I am uploading a 3 min 3D animation footage to youtube. Since youtube runs it’s own compression, I am trying to upload an uncompressed footage to avoid having 2 compressions (one by media encoder and one by youtube) which will decrease the quality of my footage tremendously.
we are still unsure what type of avi codec you are trying? rgb-yuv uncompressed? i’ve had good luck with the free huffyuv codec you can download for free, but honestly, full RGB uncompressed is borderline too much unless you want to upload hundreds of GB/sec. Any 4:4:4 or even 4:2:2 10 bit wavelet or dct codec should be fine. If you want a little trick, try Cineform since it uses wavelet and so does not compress as macroblocks in Discrete blocks.
I’d suggest rendering using one of the Apple ProRes codecs. This will give you a very high quality lossless video and has the benefit that should you need to compress the video, you’ll be able to render from this video, instead of re-rendering your comp.
I did notice from your other post though that this is intended for YouTube. I’d suggest rendering out using the H.264 codec set to Match Source, High Bitrate – YouTube is going to compress your video anyway and this option has always been successful for me.
