DVD vs Apple TV CQ 62% at 1080p, artifact question

Post by unimatrix0 »

Hey guys I've been noticing jagged edges on some of my encodes, I'm not sure why but it's been bothering me quite a bit. This may be normal but I just don't remember having these jagged edges before, so I'm not sure if I changed a setting or what. The artifacts are seen when the video is shown on a 1080p screen. The encode was done using an Apple TV preset with Cabac on, Trellis 0, and CQ ~62%, RF19. Below is a comparison of the HB encode vs the DVD, enlarged on VLC to fit the 1080p screen; notice the edge of the face isn't anti-aliased properly as the DVD:

Does anyone have any idea on what could be wrong? Dark_Shikari suggested changing the AQ-Strength, which I did but it didn't seem to make much difference.

Re: DVD vs Apple TV CQ 62% at 1080p, artifact question

Post by cvk_b »

The dev who uses mkv the most uses this:
  • < j45> generally, for blu-ray i use constant quality 59% and these x264 opts
    "ref=2:mixed-refs:bframes=3:b-pyramid:weightb:analyse=all:8x8dct:me=umh:subme=7:b-adapt=2". Full resolution 1080p encodes come out to about 8 to 10 GB.
Also, you should not be setting a level. x264 will do it for you and get it right.

I'm just throwing sh1t against a wall here, but you may want to try disabling psy-rd (psy-rd=0,0). It has a tendency to add high frequencies which usually improves perceived quality. But it may be having the effect you're finding objectionable.

Try removing the level - it may be limiting you too much.
