Hi,<br><br>I am a newbie to x264. I had two questions regarding the PSNRs in H.264.<br><br>1. I have an 8 bit .yuv input file input to the x264 encoder which gives me an 8 bit encoded stream. This encoded stream is decoded by a 8 bit decoder and lets call the output as 'Stream 1'. Next, I have a 10 bit .yuv input file input to the x264 encoder which gives me an 10 bit encoded stream and is further decoded by a 10 bit decoder. Lets call this stream as 'Stream 2'. My question is how do we compare the PSNRs of 'Stream 1' and 'Stream 2' or what is the best was of comparing the quality of the streams 1 and 2.<br>
<br>2. My second question is how is PSNR calculated between an 8 bit .yuv input file encoded using 10
bit-x264 (in High10 profile) and the 10 bit .yuv output file decoded
from 10 bit h264 decoder.<br><div class="gmail_quote"><div><br>Thanks,<br>Sandeep<font color="#888888">
