hey..
i burned XViD version of Cellular and i tried watching it with my Tensai te-div800 dvd player..
its playing very slowly... its a problem in all the xvid movies in this dvd..
however, in the box of the dvd written: "reading divx3.11,divx5.x,xvid files"
so what is the problem?
I have some problems with XviD files, too. Some videos judder. The player can play XviD. Many files run very nice and smooth. Does the problem disappear when I convert the XviD files to DivX?
I thought about a 2-step-conversion. XviD --> large uncompressed file --> DivX .
Since my Philips can play XviD, I think it might be some "picture improvement" things activated by the person who converted the file, that the player doesn't get along with.
Well your problem would I think be due to packed bitstream and > 1 consecutive bframe. Common problem with a lot of MTK based players. Easily fixed by using MPEG4Modifier to unpack or a firmware update if Phillips have released one.
If a file uses > 1 warp point GMC then the video will also stick on each such s-vop. MPEG4Modifier will also tell you if GMC was used though and how many warp points (XviD is always > 1 anyway).
@ celtic_d: I downloaded MPEG4Modifier and tested it with several files. My Philips 720 SA doesn't seem to like packed bitstream. The good files were unpacked and the bad ones packed. So this worked fine! Thanks a lot! Important lesson learned.
But one DivX file isn't running smoothly. It had packed bitstream and even with unpacking it, it didn't really get much better.
One problem file has GMC (3 warp points). How can I get rid of GMC? I can't change anything with MPEG4Modifier here.
DivX with packed bitstream should be fine. So should XviD or anything else if it is only 1 consecutive bframe. Also DivX I believe doesn't use pb if there is > 1 bframe.
For 3 warp point GMC, you need to re-encode the file.
What's the best way to reencode an XviD file? Directly from XviD to DivX with Dr.DivX? Or do you go that way: XviD --> MPEG2 --> DivX/XviD. I would like to retain the good quality of the file.
Indeed. Packed bitstream is no problem with DivX. I also have some XviD files where it isn't. They do have a lower bitrate (700 to 900 kbps compared to 1000 kbps and more) than the problem files.
Files that are ok should only have 1 consecutive bframe. You can check this in MPEG4Modifier.
XviD-->MPEG2-->XviD is a bad idea. Better to just do XviD-->MPEG2 and author as a DVD or XviD-->XviD with one of the MTK profiles that I added. Just make sure that you don't have packed bitstream enabled if you are using > 1 consecutive bframes and also be careful if you are using a CQM (Custome Quant Matrix) as MTK chipsets don't like some of them. Could also encode using a DivX Hometheatre profile (in DivX or XviD) and it should work on all standalone DivX players.
