cheers nihim, yes i have now got divx on my n95 8gb and want to get in sync avi file onto it. it looks that those files you link to are in sync but i would be able to see it better on an actual film clip where you can see the mouths speaking

[nihim]

ok i ll make from a movie, but later today cause i am leaving with some friends to go for a small trip. If u want recheck the vids and see when the letters highlight the japanese with english characters, that should give you a pretty accurate idea(?).

i' ll edit this post when i am back.

http://files.filefront.com/16+blocks+divxavi/;9793444;/fileinfo.html

try this for synch, ignore the video quality

----------------------------

also if anyone can help, i am expierencing a problem where n95-1 refuses to play an mp4 coded with h264 and AAC audio codec, and says unable to play audio or video will try seperately and just plays the audio.
Now i have re made this file 2 times making sure for the settings but still the same prob.
Only thing that i can find is that super says it's codec with apple audio and itunes info

f you want to use Super to convert video files here's some detailed information:

[el_loco]

nihim, it's very easy to spot what's the problem.

The resolution of the non working file is not supported.

448x256 is not a supported resolution for H264 it seems.

It should be QVGA or QCIF or CIF.

If you don't know what these resolutions are look here:

cheers el loco. your mp4 settings are different to the 'best' settings i had so far come across. you have the video bitrate at 528 and the ones i have used are 768 and the audio bitrate at 64 and mine are 128. what difference should this make?
Also the main settings i was after a 'best' for were the divx ones but your linked post doesn't show these. can you please either share these with me to avoid the audio sync problem or give me a link to some settings. the file that is out of sync on divx is fine with the above mp4 settings.

[el_loco]

I think you need to be careful when you say "best"

The settings I propose are the "best" IMO for compatibility, trade off of quality vs. size.

Well in your example I'll assume you have H264 codec. Then the difference between 500 and 800 kbps of video IMHO are negligible, so at 768 kbps all you have is just a bigger file of "almost" the same video quality. But if you can see a difference and you can live with the bigger file size then it's ok. The audio bitrate is almost the same comment. The benefit in audio quality is not so great as to make a big case to have 128 kbps bitrate. Again it's IMHO and feel free to continue using 128 kbps.

Audio sync problems elude me a bit. In my experience, these issues have nothing to do with the settings I use. I use the exact same settings and sometimes the video is out of sync.

I have DIVX files that work fine at QVGA or CIF or other sizes and different bitrates. If you are converting a DIVX file I suggest you convert it into an MPEG-4 file (either mpeg-4 or H264 codec).

Also want to point out that DIVX is one codec and XVID is a different codec and both codecs can go into an AVI container. Also Ideo Video, YUV2, YUV9 and other video codecs can be in an AVI container. So don't assume . Check what your video source REALLY is.

higher bitrate means better quality and bigger filesize
basically bitrate is the nr1 thing that controls filesize. But above some bitrate n95 will find it hard to play it back. So you can play with it till you find something that you like ( for me 240 is pretty good since i have a lot of episodes to avoid filling the card.

MM el_loco so you say that the n95 can't playback that resolutions? because the pc can ofc any resolution. So i should make it 176:144 which is closer to widescreen.
Hadn't thought about that thx.

for widescreen files what resolutions are accepted?

[el_loco]

The screen resolution of the N95 is QVGA 320x240.

So if you use QVGA resolution videos you get a 1:1 ration (so no scaling is necessary) this means that the screen in the device is 4:3 (in landscape mode).

QCIF 176x144 is too small a resolution to look good in the N95 so I wouldn't recommend it. Plus that's not the same aspect ratio as the screen so stretching or black bars will be added. Just re-encode the video to QVGA.

"widescreen" formats are many

TV widescreens are 16:9 1.77778

Old movies are 1.85 aspect ratio (most of them)

New movies are 2.35 aspect ratio.

I think there are other aspect ratios as well.

Made for tv content is 4:3, for old CRT tvs, (VHS tapes and Pan&Scan DVDs)

Then there's the anamorphic aspect. Basically on DVDs the pixels are rectangular not square so that the reported resolution and the actual screen size doesn't match anymore. It's complicated.

To get rid of the black bars is very complex and requires multiple passes on the encoder as you need to crop, extract and then crop again and then resize.

You can play a video that's 320x112 or 176x96 or 640x396 but if you encode a video at 320x240 (with the black bars) and encode the same video at 320x112 (without the black bars) they will look exactly the same in the N95 and the video size is comparable as the black pixels get highly compressed.

cheers guys.

el loco, your mp4 settings are very good and i will use these from now on. however, i still can't get this file to play witout sync problems so i dont think i will use divx anymore now that the standard realplayer is fine. it is a shame as the divx player seems better to me but i know it isn't the file being bad as it plays fine on both the pc and n95 with mp4 settings.

[rossonero22]

I'm new here and i found this topic very interesting as I found the same problem in my N95 8gb
el loco...i would like to read your blog but somehow i can't....

[el_loco]

Sorry, I had to take down my blog.

[rossonero22]

oh...so unlucky...
well, can u tell me what setting is the best for converting the mp4 using SUPER?How do i configure the setting?

[el_loco]

Settings that work. Not so sure what you want (best video quality, best audio, reduced file size, best for tv-out, etc.)

Container: MP4
Codec: MPEG-4
Audio Codec: AAC (mpeg4 AAC)
Video Resolution: 640x480
Aspect ratio: As per your source video
Frame Rate: 25 fps
Video Bitrate: 1200 kbps
Audio: 48000 Hz sample
Audio Bitrate: 64 Kbps (you can go higher if you want)

OR

Container: MP4
Codec: AVC (h264)
Audio Codec: AAC (mpeg4 AAC)
Video Resolution: 320x240
Aspect ratio: As per your source video
Frame Rate: 25 fps
Video Bitrate: 512 kbps
Audio: 48000 Hz sample
Audio Bitrate: 64 Kbps (you can go higher if you want)

OR
Container: 3GP
Codec: MPEG-4
Audio Codec: AAC (mpeg4 AAC)
Video Resolution: 320x240
Aspect ratio: As per your source video
Frame Rate: 25 fps
Video Bitrate: 768 kbps
Audio: 48000 Hz sample
Audio Bitrate: 64 Kbps (you can go higher if you want)

[rossonero22]

Is that optimum to my n95 8gb?What I looking for is the best video quality without sacrify too much of the mass memory....

[el_loco]

Yes those are optimal.

[rossonero22]

oh...thanks...
about the aspect ratio...what you mean by "as per video source"?how to configure it?

[jericho]

Aspect ratio is dependent to the quality of the video you are resizing/editing..

[el_loco]

If you don't know what aspect ratio is just leave the default settings.

[rossonero22]

The default is 1:1 or 4:3 as the SUPER already set?
I got read some of your messages in other post and you claim that should choose 16:9 as the aspect ratio in the SUPER,what does that's means?

[jericho]

Aspect ratio is simply a comparison of the horizontal resolution of a display and the vertical resolution of the same display.

Your AS would depend to the screen size of the medium where you'll be watching the video..
