yeah just read all that. but like i said i tried this...
Video: 150kbps Constant - 20fps - mp4
Sound: Stereo 48kbps - 22hz
I split the film in half aswell to save time fast forwarding and rewinding.
During fast moving scenes the phone just cant seem to keep up! The video slows down, jumps, and sound goes alltogether until the action calms down again.
Am i the only one experiencing this?
Sorry just realised u edited ur other post, i'll give that a go then cheers

hahaha, were editing away here.
Thing to remember is also, if you want smooth playback, lower fps will allow higher bitrates, while higher fps will require lower bitrate to play smooth. It may be able to play high bitrate and it may be able to play 20-25 fps, but not allways both, you have to make some compromize between bitrate and framerate to get smooth playback.
Its a trial and error situation

a note is Nero only do 15fps videoencoding
Id keep below 150kbit/s for 20-25 fps video, more around 140kbit/s to ensure smooth playback, and only go above 150kbit/s for 15fps video.

eh, I have a 25 fps 3½min clip on my phone, and it certainly does not drop any frames. Plays smooth as silk, and keeps synch perfect.
You can put as many "eh's" here as you want, but it still won't be 25 fps in the device. SE would definitely mention that in the specs, but they don't. You know why? Because it ain't capable of doing that. You can play the clip encoded with 25 fps, but it won't show you 25 fps in the device.
You are mistaken my friend. The 25fps Eric Prydz video I encoded plays 25fps on the K750 just fine. No matter what you say it's sooo much more fluent than 15fps. It looks exactly as smooth as the original video on the computer. When I encoded it using 15fps it doesn't have that smoothness to it at all. Looks artificial. The video I encoded uses 256kbit/s video and 128kbit/s audio. Works like a charm and outclasses any 15fps video I have EVER seen.
Download and try my Eric video and see for yourself. (Note: Sometimes the movie stutters, sometimes it does not. If you put it on phone memory it plays through almost every time with full framerate)
I have a 90Mb full episode of the latest Top Gear in 192kbit/s video and 128kbit/s audio 25fps that plays flawlessly and with full 25fps throughout the entire clip. Even if it's placed on the memorystick.

ImTOO 3GP Video Converter... You need the registered version to be able to have more than AMR 8khz audio quality...
I can post the settings used for the Eric video if anyone is interested...

Im not to glad about IMtoo converter myself, dont think quality is optimal. Took a look at your clip and its certainly ok, but beleive Nero Recode or Xvid could do just as good with only 150kbit/s
I also think 128kbit stereo AAC is overdoing it quite alot.
I find Xvid or Nero Recoded 130-150kbit/s video 40-48kbit/s audio to give an optimal kompromise between quality/playbacksmoothness and filesize. And these settings also only generate half the filesizes your settings does.
I also think your clip needs to be cropped to fill the screen. I dont like clips to have to much black bars top/buttom, the screen isnt to big as it is.
Just my 2 cents
Heres an examplevideo that demonstrates these settings I find to be adequite quality. I encode all my clips like this one.

The clip is in correct aspect ratio, that means everything has the right proportions... that's important to me...
And 128kbit/s audio is an absolute minimum in my opinion since anything lower sounds really rubbish.
And I'm using Imtoo MPEG Converter... not 3GP... my mistake...
Well... proove it then... encode a video for me using the settings you like and I'll encode one and then we can compare them...
