Colorspace effect on bitrate of raw footage?
I record gameplay footage for my LP youtube channel, and I've been using lossless codecs for recording, to squeeze as much quality as I can into my final videos. Currently, I record using the RGB color space for 1080p60 footage, but that pushes the IO limits for my current recording setup. Would switching color spaces save me any bandwidth without causing a noticeable drop in quality? I encode to h264, using YouTube's suggested bitrate and other encoding settings. (16 Mbps data rate for the final video).
Even a 10% savings on the raw bitrate for my footage would probably help a lot.
Go with YUV 4:2:0, that's what Youtube/H264 uses anyway, it'll cut your recording bitrate in half (actually less than half, so even more).
Edit: BTW Dxtory presents RGB to the codec always, but the codec will do the conversion on-the-fly.
Thanks for the tip! I'll make sure to do that.
