actually i think encoding and converting might be the "correct" place.. not general video, however you shouldn't make new threads when you want to "move" something, you should "mod drop box" it and ask them to move it, and if they see its fit to move it then they will.

more than likely the issue is with the file either being "too good" or something to do with zarxgui.. O.o or meigui and how people encode their mp4s here..

I'm not sure if the x.246 codec is compatible with psp, but I know I have the same issues with mp4s and my ipod... A lot of files I've had to re-encode in order to get it to play on my ipod. Perhaps looking into a media encoder and having the cccp pack on your computer might help you to re-encode the files.

Install CCCP and the PSPVideo9 and convert it with PSPVideo9.

PSP has limited CPU power and decoding abilities. That is a lot of H.264 features that people use on a regular basis aren't supported by the PSP (because they require too much CPU). Also resolution is often too high for it to handle, so you will need to convert the files anyway.

Actually, the PSP's issue isn't so much CPU related. It's CPU us fast enough to support all Main Profile h.264 encodes.

...That said... I have just finished beating the HELL out of my PSP and PSP Video 9. The main issue is the PSP is finicky as HELL.

The PSP supports THREE resolutions: 720x480, 480x272, and 320x240.

The PSP supports FIVE frame rates, and it's REALLY damn anal about it: 30fps, 29.97fps, 25 fps, 23.976fps and 14.985fps. . AND HOLY HELL is it picky. Even if your file reports as 23.976fps it might not be '23.976y enough' for it's requirements. This is where I found the PSP will mostly go 'Fuck you, unsupported data'. Even though the resulting MP4's claim to be of the proper frame rate. I found that editing the profile and changing the 'Resolution' pulldown menu in the frame in the 'general' tab under the video section of your profile to '23.976' (Or what ever your target framerate is) instead of the default setting of 'Original'.

You'd THINK that if you put in 23.976 video that leaving at 'original' would work, wouldn't you? NOPE! I've had encodes that resulted in 'Unsupported data' that worked FINE just by changing that one setting in the encoding profile to the specific frame rate and reencoding agian with nothing else different.

I find that the PSP is a dream for video but only once you've figured out every damn quirk it has in reguards to video specifications.

I've been working on my own set of profiles for PSP Video 9 that I might be willing to share that are 'idiot proof' if you have AVISynth and CCCP installed. But most people might not be thrilled with my using only 256kbps for video and might want to customize it themselves afterwards.

I definitely agree that the PSP is finicky in its H.264 support, but you've got some things wrong.

First of all, not only 720x480, 480x272 and 320x240 are supported. As far as I know, the real list is: 720x480, 352x480 (I have no idea why someone would ever use that resolution, especially on a PSP) and anything that is mod-16 and does not exceed a width of 480 or a height of 272. In other words, you can use 368x272 as an optimal resolution for your 4:3 videos.

Secondly, in my experience, the PSP can handle pretty much any framerate you throw at it, as long as you run it through the AviSynth filter NiceFPS. In fact, it even supports variable framerates! (Not that you'd need this a lot, but the GUI I've written for my own use does this automatically by extracting the timecodes with FFmpegSource and running them through tc2mp4.) This appears to be your problem.

More fun facts:

The PSP does not support CAVLC, only CABAC. This means that you can't make a H.264 file that works on the PSP and the iPod.
If you don't use --sar 1:1 for non-anamorphic videos, you'll have to manually correct the aspect ratio every time you play a non-16:9 video. For some reason, the PSP thinks stretching to fit the screen is the best solution here.
--ref 3, tops.

hmm I was just wondering..see once I've converted the video file using PSP video 9 and it plays fine?Is there any way to make the file size smaller?I can only fit about 4 episodes just now

Edit the profile and decrease the birates, of course.
