Best video parameters for Divx mobile player?
Mon, 01/05/2009 - 22:44
Hey there,
I wanted to use Divx Mobile Player to see my videos through my N95 8Gb.
For now, with my Xvid settings, i'm only able to hear the sound, but not to see the video.
I ripped my videos in two qualities : a "bad quality", using Xvid settings in 2 passes, Bitrate 5000, Target quantizer 2.5, audio lame MP3 High quality, and a high quality using X.264 for an .mp4 output (not useable in this player).
I wanted to know what are the best parameters to render smooth, best quality videos through Xvid mobile player for my cellphone.
I use Megui for ripping and muxing, using an .avs script generated through Ri4m, but if there's an easier way to re-ripp my videos to fit them for my N95 in high quality, i take it !
Thanks for all your advices ;-)

For the best results, we recommend using DivX software to create your videos. Unfortunately, we can't provide much help if you are using other software (like Xvid).
DivX Converter is free and easy to use. Dr. DivX is more complicated but offers much greater control over how you encode your videos. You could also use something like VirtualDub which is not created by DivX but does use the DivX encoder. I create almost all my videos using Dr. DivX or VirtualDub.
Nonetheless, the DivX Mobile profile looks like this:
MPEG4 Simple Profile
B-VOP: Not Allowed
PAR: 1:1
QPel: Not Allowed
GMC: Not Allowed
Interlaced: Not Allowed
VBV Max Size: 655360
VBV Max Bitrate: 600000
Width: 320
Height: 240
I have tried using FFMPEG with libxvid to create Mobile videos and found no way to control the VBV Size. Xvid seems to ignore the "-bufsize" option on the command line. Here is the command line I found that *almost* works:
$ ffmpeg -i input.mov -vcodec libxvid -vtag DX50 -s 320x240 -aspect 4:3 -vb 600k -maxrate 600k -bufsize 655360 -bf 0 -acodec libmp3lame -ab 128k -ac 2 -ar 44100 output.divx
Again, the bufsize arguement seems to be ignored so this command will not create DivX Mobile compliant video.
By the way, X.264 is not Xvid. X.264 is a different encoder used to create H.264 video. Xvid only creates MPEG4 part 2 video.
