Why can't I play video on my phone?

I have a iphonek808 china phone, it supports 3gp video,but when i download it, the video wont work on my phone

• yes, the phone accepts 3gp video, but when i convert or put some of my videos my phone wont play it,,ive tried different formats but still i cant crack it...by the way it captures video in .vid format, and its too short,,anyone out there who has a much similar phone that i have,pls help me with my dillema

• Answer:

  I don't suppose it's Chinese localisation problem - from my experience I've found 3gp format quite problematic, many programs can covert to it, but for me only few seemed to work. (aka gave playable output) Try using SUPER (http://www.erightsoft.com/SUPER.html). ^-^
