View Full Version : Instead of 1920x720@1:1, 1920x1088@24:9, better?

Hi guys.
I'm looking to do some very high quality BluRay encoding and I wonder if there would be any visual quality benefit to rendering at 1920x1088, but with a pixel aspect ratio of 24:9, so the end result would be 1920x720, as opposed to rendering natively to 1920x720 (with square pixels). Would "squeezing" the image in such a manner help further reduce compression artifacts, or is it that if the same bitrate spent on 720 vertical pixels would ultimately yield more or less the same quality since less compression would need to be applied to lower vertical resolution.
Please let me know if I confused you to death.:D

If this is for blu-ray those PAR's and resolutions are not legal.

Only 1:1 (or 4:3 for 1440x1080 interlaced) ; if you need other AR's than 16:9 then you need to add borders

Yeah.
The PS3 only accepted a non-BluRay MP4 encoded that way.
Thanks for the reply.
