How do I encode to MP4 for my SE K750i Mobile phone?

[the loc-man]

Hi I am getting a Sony Ericsson K750i mobile phone, it has a 176X220 res screen. I want to be abler to encode videos for watching on it. It support MP4. This is the exact codecs it supports from the SE site

Video (including audio part):
- MP4 (video: MPEG4, audio:AAC or AMR)
- 3GP (video: MPEG4 or H.263, audio: AAC or AMR)

Can you tell me how to encode to this from a DivX video file or whatever please? I have pocketDVD studio for my PPC but this does DivX.

I dont understand what a MP4 is, I only do DivX and Xvid for my Archos Gmini 400 and my iPAQ 2210.

hope you can help
thanks

DivX = MPEG4. You just need to remux to mp4 using something like mp4box.

XviD is also MPEG-4.

See if there if tells you anything about what profiles it supports. I suspect that it is SP only.

mp4 is a container, like avi, but with more advanced features like menus. It is the offical MPEG-4 container and is somewhat based on the Quicktime mov format.

An interesting read would be the mp4 faq over at doom9's.

mmm?? the divx files I have have a mp3 sound.

would I not need to convert these divx to MP4?

is there a "all-in-one" from DVD/vid file to MP4?

bit confused about MP4, I thought I had just grasped DivX

cheers for the reply

mp4 is just a container, read http://forum.doom9.org/showthread.php?s=&threadid=62723
as celtic mention.

divx avi with mp3 to mp4:
Convert the mp3 to aac using using for example dvpoweramp.
then join/multiplex the divx avi with the aac audio and make a mp4 using yamb (a gui for mp4box).

thanks for that I will look into this, I like all in one utilities, is there anything that goes from DVD or a divx video file straight to a MP4 format the SE 750i would regonise?

thanks

mp3 is allowed under the mp4 specs. Guess it isn't supported in this case though.

Well since you would probably have to resize, you are going to have to re-encode even though your source video is MPEG-4 compliant.

If you have Nero, check out Recode. doom9 also did a nice mencoder GUI. With it you can encode with libavcodec or XviD to an mp4.
