I think all players on the market right now can only handle DivX3/4/5 and XviD fourcc and refuse the play the rest.wierd, i suppose you changed the fourcc of the nd and 3ivx clip. I guess that the problems are maybe caused by my sample files (it seems that with the one sample the player can play till the first keyframe (at ~5sec), the other files have a keyframe shortly after the beginning, which maybe caused stopping at ~1secĪnother possibility would be that the mediatek chip claims to support the decoding of error resilience but their implementation is still buggy.Ĭouldn't get the mp4v to work though, it just skipped those files, similar to how the player treats ffvfwcrap, i dont understand why they cant add mp4v, its the official mpeg-4 fourcc :rolleyes:īut anyways, thanks a lot for your tests :)Įdit: hm, did you already try to play a xcd? a xcd is similar to vcd but for mpeg-4 (you can store around 800mb on a xcd)ītw, I tested ND and 3ivX on my elta 8882, and the latter would not work no matter what I tried (and it's only MPEG-4 simple profile so you'd expect the player to not have any problems).
#Divx pro highest bitrate Pc
The other 2 just play for about 1 secondhm, interesting resultsġ) which fourcc did work? all you listed? (btw divx4 doesnt exist, it can only be "divx" - 4 letters)Ģ) well, as normally a player, who doesnt understand error resilience, cant even play such a file (try for example to decode the files with the 3ivx decoder on your pc to see how it would look like), the chance is great that the gran prix can decode it (and uses the same chip as the elta 8883)! The first clip (1st-pass_data-part.avi) runs smoothly for the first 5 seconds, then hangs I tried FourCC (changed with nic'smini avic fourcc changer) with DIVX4, XVID, DX50 and mp4v The best thing is maybe to change both to the same setting what is the "FourCC used codec" option in the fourCC changer?good question, i dont know :D
(didn't even start)ok, i thought that it wouldnt know the ffvfw codecītw. It didn't play any of the clips with the clips with fvfw FourCC.

If you have less than that, then the image quality will suffer. I don't remember the actual math, but it basically comes out to >= 0.20 (bits * pixel / frame). Then, you find the maximum resolution you can reasonably use, and encode it like that.
#Divx pro highest bitrate movie
If the movie is longer, you either have to increase bitrate or the size, depending on your priorities. So, when I encode divx movies, I use a bitrate calculator (there are many available for free, I even wrote one myself), to find what's the highest bitrate I can have to make a movie of a certain length fit a certain size. Obviously you want to have as high resolution as you can, and that means also keeping the bitrate high enough. Increasing the resolution will only make things worse. To fix this, you can either increase bitrate, or decrease resolution. With compression, each pixel in a frame only gets so many bits to store color information, and if you lower the bitrate too much, a good portion of that information will be lost.
Here's how it works: The image quality depends on 2 things -Įach frame in a movie is composed of a fixed number of pixels, and has only so many bits to store that information.
