[HELP] what's the best way to QTGMC Deinterlace with no loss by using Hybrid?

If you want to deinterlace you need to reencode.

Cu Selur

yes, i reencode with x264 and x265 for test, but the result is a little different.

the right is x264, left is x265


why x264 seems more lighter, or to say, x265 is more darker?

the original 1080i bitrate is 17300, i using x264 average bitrate 1-pass, half of bitrate 17300, the number of 8650 to encode, because i learn from internet that mpeg2 to mpeg4 with x264, using half of the original bitrate can get the same quality.  

and x265 using average bitrate 1-pass too, bitrate is 1/4 of 17300, the number of 4330, because i learn from internet that mpeg2 to mpeg4 with x265, using quarter of the original bitrate can get the same quality.


the quality seems almost the same by both using x264 and x265 for deinterlace, but why the little difference occur, x265 seems more darker, and x264 seems more lighter


and this is the 1080i original snapshot:
