Hey all, I've got a problem playing my self-made divx and xvid files on my Sharp HT-M700H home theater player and hope someone can help me.
I don't know what "chip" it uses, and I've not found anything about in in searches (searching doom9 for "sharp" is kind of futile). I've tested the test clips that where recommended in a thread about buying standalone players (clips with b-vops, n-vops, cmc, divx and xvid) and it could play all except the xvid with cmc+b-vops. My problem is it seems to not like high bitrates at all, nor medium bitrates at high resolution. This is not good for me since what I want to do is encode 1920x1080i HD streams to xvid and put on a dvd-rw. The maximum output resolution of the player is 720x480 for ntsc (I tried higher but it says resolution not supported).
The first thing I tried was a 720x480 q2 xvid encode, with ntsc home theater profile, that ended up 2.5gb with sound. When I put this in the player it stuttered right away from the opening scene, and the bottom ~1/3rd of the frame kept flickering black.
I read that CQ encodes break home theater profile, so I did a divx 2-pass encode with average bitrate 2500 with ntsc home theater profile selected and it got a little better but still the same problem in action scenes and at scenechanges.
Thinking that maybe the 2pass encode still had too many peaks in the bitrate I did a 2500 CBR encode (that ended up as 2200 average bitrate in the end, I forced minimum quant=2) and it still had the flickering in scenechanges and fight scenes.
I then tried AutoGK (xvid), with ESS standalone support plugin selected, 2gb filesize and max width 720. That file actually came out quite playable, with only 2 little flickers in the first 10 minutes I watched, but the resolution came out 704x384 so everything looks terribly short and fat on the TV. Although it's playable it's really not a useful option for me unless there's some way to force the output resolution in AutoGK to 720x480. The only thing that stood out to me with this one was the program turned off b-frames because the first first-pass came out too small.
I just now tried to "copy" everything that AutoGK did and encoded a 704x464 version with 1800 average bitrate in MeGUI. It came out as the worst try yet! :o
I hope someone can help me or point me in the right direction. I realize the post turned into quite a story but I wanted to give as much info as I could. Thanks.
EDIT: I forgot to mention I use divx 6.2.5 pro and the xvid version that comes with autoGK (1.2-127).
All encodes with packed bitstream off, gmc and qpel off, default b-frames settings.
Tested both h263 and MPEG matrix.
No filters used except resizing, in the codec when using divx, avisynth-lanczos when using megui.
All files play perfectly on PC.
