No offence

- but it seems some people dont search or read the pinned threads before posting questions as the same questions are getting asked and answered over and over again. Noone mind helping where they can - but it can be just a litle bit annoying to have to write the exact same answers to the exact same questions several times each day in different threads being posted directly beneath other threads with the same questions and answers - therefore please take the time to read this general info first - thanks

1. Mobilephones capable of playing video mostly use the .3gp or .Mp4 standard. (Allthough others, typically smartphones, can also play video based on windows media or realmedia)
3gp and mp4 are videocontainers - that contain a videotrack and an audiotrack.
The videotrack can be encoded as either mpeg4 or h263 and the audiotrack can be encoded as either AAC or AMR.
In general, Mpeg4 video is higher quality than H263 video, and AAC audio (designed for music) is higher quality than AMR audio (designed for speech)
-----------------------------------------------------------
2. Different mobiles support different combinations of these formats. Some like K700 support all combinations - while others like N6230/6600 and Motorollas only support combinations with AMR audio. Therefore a .3gp/.mp4 video encoded with mpeg4 videotrack and AAC audiotrack for the K700 will not play sound on a Motorolla because this only support AMR audiotracks.
Furthermore different mobiles support different videoresolutions. Most common resolutions are 176x144 and 128x96. I will try and make a list of supported resolutions and settings for different phones and update this thread along the way.

3. There are a number of different ways and software to use when converting normal videoclips to .3gp or .mp4. Most commonly used are Mpegable X4 live, Nero Recode, Quicktime Pro, PVauthor and Nokia Multimedia Converter.
There are guides and instructions on how to use several of these in the following threads:
