Video On Cell Phones

I have a Nokia N95 (No iphone for me) and Im having some real annoyances when it comes to video podcasts. I am able to download some podcasts and watch them fine (such as GeekBreif and MobiBuzz) but other’s (Diggnation, Digital Underground, Podcast Salad). Of course all of the Twit podcasts work because they are in mp3 format. I am currently downloading Diggnation in Xvid format and watching it in Mobile DivX player, but as the video is encoded at a standard pc bitrate I have problems with video and voise sync. I am downloading Podcast salad and Digital Underground in h.264 format and/or Ipod format (not sure if they are one and the same as the both appear as m4p) I guess the best solution is to re-encode the files once they have downloaded to mp4 or 3gp but that takes far too long.

There are a couple of issues with watching video on cell phones. First, you have to get video in a format that’s supported by the cell phone’s built-in video player, or download a player that can handle the video you want to watch. Second, even if the video is compatible the phone itself might not be powerful enough to handle higher quality video. That’s why the sound and picture are getting out of sync. Experimenting with different codecs and video sizes will give you a good idea of which formats are best for your phone.

Your N95 likes h.264 best. According to The Nokia Blog, http://thenokiablog.com/2007/04/10/how-to-convert-movies-tv-episodes-vid..., choose a 320×240 resolution and a 700kbps data rate when encoding (or re-encoding) for the N95.
