Problems playing AVI's from my N82
 
I have some videos that I have taken with ny Nokia N82, they were taken on the highets quality, so the file size is quite big, about 12mb, but when I bluetooth them to the N810 which transfers fine, but when I play them the sound is fine but the video olays one frame every 10 seconds.

why is it you can take video on one Nokia device but it will not play on the other device, seems a bit strange

The resolution is too high. You need to re-conver them to 400 x whatever, or 320x180 or 320x240 depending on the aspect ratio of the video.

Thanks for the reply Eugenia..... whats the best way to convert video to play on the N810

There are specific utilities that specialize on the N-series. http://www.google.com/search?q=n800+...ient=firefox-a

I've got the N82 as well.

Try recording using "TV Normal" rather than "TV High" quality. I have found that mostly high quality did not play well on the N810 Normal did.

They both record at 640 x 680, but have a different bit rate. Even Normal is very good (IMHO)

The fact that even High seams to play ok sometimes means that
the Video is recorded at Variable Bit Rate I guess. So that when the bit rate being recorded is low, it still plays ok.

I looked at file size per second for the ones that played ok at High Quality and they were similar to the ones at Normal Quality.

That's my theory anyway.

I noticed that the ones that played badly at 'High' quality were the ones that were recorded with plenty of light and so lots of detail (therefore high 'Real' bit rate ?).

Same sort of recording on 'Normal' bit rate played ok though (and looked great), so that is my Default now.


So my advise :

"When Recording", leaving it at 640 x 480 is ok. But you need to drop down the quality to the next level down "TV Normal".

For the ones you have already recorded, you may as well optimise them for N810 playback I guess.

But it does leave me in a Dilema. I like the idea of recording at highest "quality", but I don't think the difference in quality is that significant compared to file size etc.

The main advantage for me is recording at 640 x 480 (assuming you want to play on devices other than phone and N810). Don't think the 'High' adds that much.

I'll play a bit more when there is more light around and feedback.

Would be great if you could do the same...

Tried recording on N82 with 'TV High' and 'TV normal' again outside with lots of light...

As before, both are recorded at 640x40, but bit rate stated in details is higher for TV High. File size for same sort of footage and recording length was much higher.

'TV Normal' was playable on N810 without any conversion, but not quite smooth. I think the bit rate in good light etc. is probably just tipping over the limit. Still watchable just not as good as if you convert it properly.

'TV High' setting was unviewable.

I was quite satisfied with the quality of recording on 'TV normal' (could not see significant improvement from going to higher bitrate when playing back on a PC full screen), so I think I'll stick with TV Normal setting.

Just got a N82-black :) and for multimedia purposes, it feels the N82 is like a small and working N810. I don't need to take my N810 every time like on E61 days.
Why can I play a video on N82 recorded with highest resolution and N810 sucks? The hardware specs are nearly the same. Ok, N82 does have lower resolution which don't need so much amount of data transfering to the video device.
But then, there must be a way that N810 renders down the video like on N82 to 400x240 and stretches to 800x480 on the fly to play it fullscreen.
So I can use the bigger screen on N810 to view videos recorded with my N82.

hmm.. are you using mplayer or the default player? i find that mplayer itself (without a frontend like kmplayer or mediabox) can play any avi file i throw at it.. even the popular dvd rip files..

Mplayer can decode videos at reduced resolution, which improves performance.

I tried that. Mplayer can't play videos from N82 smooth enough, even if I start mplayer from a shell.

And scale this reduced resolution to fullscreen? Thank you :) then I must read 'man mplayer' again and make this mplayer options my default player for mp4 (this is the suffix from N82) files :)
