Is Good Quality Video Possible On The 3100?

[GadgetGuy]

Hello all,

I have a Sony PSP, which has truly great video quality ( playing videos converted by me, not UMD).

I also have a very olf Pentium II - 350MHz PC with 128 MByte RAM and a 2D only graphics card, running Windows 2000: that also does OK (enjoyable) video ( in 640 x 480).

Now to the Zaurus: I have tried all kinds of tricks with Kino2, but the quality I am getting is quite disappointing. Jerky images, no usable full screen etc.

Is it me, who does not know what to do, or is the Zaurus not capable of good quality, jerk free video? If the answer is yes (i.e. the Zaurus cannot do this), then how come, that my very old PC can?

If the Zaurus can do good video: can you please tell me:
- what Kino2 settings
- what video file format ( DivX? Mpeg2? Mpeg4?)
etc. etc. to use...

Thanks for any advice

Miklos

Are you using Tetsu's special kernel? It has a variety of enhancements for video. But even without it, you can get decent video performance. I would look at your encoding settings. What bitrate are you using for audio and video? Changing to mono sound can often make a difference, as can lowering the bitrate or the resolution. You might need to encode at 320 x 240 and then blow it up to full screen on the Zaurus.

hmmmmm


answer is yes......yes.......yes..........hmmmmmm........and yes.



look down at my signature.  it will take you to my site and you can view videos on your zaurus at full screen and stereo 30fps, high quality everything.


install the kino2 from my site.  if you screw up, i recommend you start from scratch.

then download a sample video that i provide and you got yourself a video.  i placed instructions on how to create video as well.... no problems.

i also carry a video camera were it records in sd card at 24fps and i can play back video 640x480 res with no problems.




have fuun dude!!!

[Cresho]

Cresho,

thank you for the reply. I did download the short video clip from your website.

I watched it with Kino ( and I have the Tetsu kernel installed - as part of the Cacko 3100 beta ).

It does work, but it is not something I would consider "good" quality... More like: not bad, not bad, but overall still quite poor quality. I have seen other videos with the same results: quite poor quality.

Then I have tried one of the Sony PSP demo videos ( MPEG4 ), which looks good on the PSP and it did not even play at all on the Z.  The same file also plays well on my PC.

Would you (or anybody else) be so kind to point me to a site where I can download a clip, which you would consider "great" quality? Just to have an idea what to expect?

Thanks again,

Miklos

Have you got a link to one of these videos?

No. However if you do a search for SONY PSP Video Download, it will  be one of the top hits. It is an official Sony website...

If you go here

http://www.us.playstation.com/psp.aspx

and scroll to the bottom, you can download trailers for some movies.  I tried the trailers for "Guess Who" and "Resident Evil".  In both cases, they played poorly.

On kino2 sound doesn't work, and kino2 dies. VLC has trouble with them.  VLC issues a number of "header damaged" messages.

kino2 works well for a number of movies on my 3000.  VLC works OK for quicktime movies that kino2 won't play.    So I assume that there's something funky with the encoding of these movies.

On my destop Ubuntu 5.04 box, xine and mplayer don't work well for these trailers.  VLC works OK, but issues a ton of messages.

I found out that rotating the video 90 degrees clockwise during encoding makes it run more smoothly on the Zaurus. I've attached a 25-second clip from Star Wars that has been encoded in this way. It's 640 x 326 widescreen, 500kbps, mono sound, and it runs well on my Zaurus. I would think a clip this short shouldn't be a problem from a copyright standpoint, although the mods are of course free to take it down if they choose. You might need to run it twice to really see the quality, since the first time through may be a little jerky.

I use PocketDivXEncoder to encode my videos. It seems to work the best and is relatively easy once you figure it out.

I'd class that as good quality, icruise - nice work!
The nemo sample is acceptable to me: I might start encoding a few movies, as I think it really is worth it.

Thanks for the tips guys'n'gals, they're most appreciated.

Thank you - I am convinced: it does look very good! So off I go, converting some movies.... and my PSP will remain for games only...

sorry for the quality problem.  but that video was originally made to run on a zaurus from an sd card.  if you recall, you cant run video off an sd but with this format, it is possible.  the video that is shown was done low res for xaurus sl5500.  the good quality i have doesnt fit on my websites so i just decided to keep this file for specifically demonstrating video being possible to play on the z platform.

[Cresho]

yep....verified this video vs the stuff i currently encode.  demo nemo on sd is nowhere near the quality i put out for the z c1000.  I just cannot put it up because i have no space.

my videos are high quality and sound superb.  I just wish i can put out an exampleb so people can see.
