W900i - Very High Quality music video download |

Hi, i noticed everyone with the w900i seems to get different video playback quality, some people get stutters, some don't, it doesn't make much sense. Leading me to recently learn about making very streamlined efficient mp4 videos. So, i've encoded a test mp4, it's just a 4 minute music video, only 12MB.
If everyone with a w900i (especially those who get stuttering video and sound loss from mp4 videos they put on their phone), could download this and check if it plays all the way through on their w900i without any problems? Cheers!
It's a nice enough song, In The Waiting Line, by Zero 7. The video is the important part, they use a CGI video for the song, and mpeg compression always has a hard time with CGI, mpeg is designed for live action, like real people. So this should push the w900i mpeg4 decoder a bit more. Bitrate is 415Kbps combined, near the theoretical limit for the phone.
anyway if people could test it out, i'm hoping it plays fine on everyones w900i. Thanks. 
Oh and if it is fine for everyone, expect a LOT more high bitrate music videos to appear for this phone very soon. 
Here's the file, unzip and copy to your phone, then play fullscreen through the walkman -

well done, tasted on k750, playback only with sound, no video. Maybe will getting W900i soon, so will try on an appropriate phone.
Keep them comin´!

It works just fine on my w900i. Although its not truly fullscreen cuz of the top and bottom black borders, but the video and audio quality is wickedd |

it plays quite well, never had any stuttering problems but i do still have audio syncing probs. Can't really tell if the audio and video is in sync although theres nothing to indicate it's not (very smooth video and audio is great), can you post a music vid with someone singing so i can test? also can you post the settings/progs you've used to encode the vid?
Thanks. |

pv-author will choke on really high bitrates, i've tried it. :/
Anyhow, expect a comprehensive encoding guide to be posted tomorrow. It'll cover simple methods using nero recode / imTOO encoder / Mpegable x4, as well as a more complex but much better quality encoding method i used for that test video.

Great video and audio playback for me. I've been playing with the encoding for 2 days, it's kinda time (and battery) consuming Anyway, I focused on 3GP files, using the 3GP converter (XVID+AAC) and short music video (like yours) looked great.
But encoding the shortest movie I have (1:26:00) with settings 190 kbps, 25 fps, 320x178 size, 2 channel AAC (32bit, 16kHz) produced a beatiful video for first 20-25 minutes, then the stuttering began and the audio track went off-sync. Maybe splitting the movie in few parts may help, I have yet to try that solution.
Anyway, I'm glad there's someone experimenting with the encoding as well |

Ok chaps, the encoding guide for the method i used is up! it's a bit too involved for a forum post, so i made a small site dedicated to w900i video encoding and playback.
The high quality encoding guide is here - http://www.vapulus.com/w900i/quality.html
the site index is http://www.vapulus.com/w900i/
the site contains detailed info on the w900i video capabilities, as well as simple video conversion guides for nero recode, mpegable x4, and imTOO encoder. I recommend using the high quality guide method though, as it allows video bitrate up to 400kbps paired with 96kbit HE-AAC audio!
now i really need a drink! |

tom.k the problem with longer videos like full movies is addressed in the conversion guides i wrote on there. In short the stuttering after 20 minute or so is caused by how the phone buffers playback, it uses it's internal memory. So if you're already playing a video from the internal memory, you get problems. The easy solution is to buy a Pro Duo card. But don't worry, there's also a way around it if you don't have a pro duo card and won't have one soon. That involves a video bitrate of only 250kbps and most importantly using on 32kbps lc-aac audio. Anyway, read the details on the site. |

okey i will download and try, have been fighting with this since i got my w900i, the video lag and out of sync sound in full legnt movies, but i use the internal memory have nog memCard yet. but i never manage to get a good result, mostly coz problems spliting my movies. "error 30 i guess" =D becaus 30mins mp4 192kbit video 64kb sound works but not much longer than that. downloading the vid as we speak.

Seems to work like a charm, but hard to notice if the sound os out of sync when there is no "lip movement" in this particular song/video
and no real FS black borders.. that must reduce the use of bitrate/quality needed? and therefore use less "cpu/buffer" ?

skibbe on long videos when using only the phone's memory, you must reduce audio bitrate to 32kbps. Read the website, read the encoding guides, all the details are there. |

Wow, great guide! And good thing that I ordered a 1GB SanDisk yesterday |
