[QUOTE=Gary Parent;2031629]I have never experienced pixelation with a conversion, from the very first release. Why now?
It seems that with versions later than 22.214.171.124, I am occasionally getting pixelation after converting xxxxxxx.mxv file to NTSC DVD. This is from a Blu-Ray source made into MKV file. Nothing wrong with original file.
I experimented with a 3 minute clip and got pixelation but I was doing some heavy downloading in the background.
I tried it again and I got no pixelation. This time I had nothing else running while the conversion was in effect.
Is there some time dependent factor whilst converting MKV(H264) to MPEG2, where you should not run any other job while converting?[/QUOTE]
Convert X does decode H264 codecs, but if it’s a BD codec then it won’t. However, you may want to ensure that you have the most up to date codecs installed. AVI Demux is a good program that will automatically search and install the latest codecs available.
Is the pixelation on your monitor or your TV? If it’s on your monitor, then that can be common, since your monitor runs at a higher resolution than a TV screen. Keep in mind that DVD runs at 720x480 resolution, not the 1280x720 your HD source is at.
If you are getting pixelation on an upconverted image, then the pixelation dithering is also common, as you are artificially converting a 720x480 image to 1280x720 pixels… However it shouldn’t be dramatic pixelation…
