Ghosting woes, possible solutions?

[The.Yield]

Hello all. Long time reader, first time poster.

As of late I have become very annoyed by the amount of Ghosting/Smearing taking place on the PSP screen while playing encoded videos (AVC or Straight MP4).

From what I've been reading, the "very low refresh" rate on the PSP's screen is a huge factor in this. Also from what I've read, anything that has had it's framerate upwards converted with standard frame doubling makes it even worse. It has something to do with the identical frames causing the pixels to fire twice as long, making the pixels more stubborn and less likely to change to the new frame (so the Ghosting/Smearing appears). Since the PSP has to display 29.970, that is a big problem. Most of my video is 24/25 framerate.

Is there any truth to that? If so, what can be done about it?

What I use now is PSPVideo9. Which, as some of you may know, it nothing more than a fancing GUI for FFMPEG. I take some slightly modified Xvids (smart smoothing in Vdub, hehe) and pipe them right into PSPVideo9. Of course, PSPV9 changes the framerate to what is needed...

As I understand it, FFMPEG uses frame doubling to change Framerates. Is there any alternitive method that can be used? If not a completely different method, then maybe some flags than can change the way the duplicated frames are handeled?

All my feverish googling has yielding nothing of significance. Save for a neat little program called MotionPerfect. Sadly I could not get the demo to work on my PC. I also found a post from someone who said that he had some mild success REDUCING the ghosting effect with FFMPEG flags (something to do with how the dup'ed frames are handled, as I stated before--couldn't get any info on exactly what those flags were though).

Any insight into this issue would be gangbusters.

Shameless bump (enough time has gone by).

No one has any insight on this? Are any of my questions coherant enough to even answer?

Hi,
Have you tried the forums at the Videora website?? I don't use PSP 9 but I use their Videora iPod converter which is also a "fancy" frontend for ffmpeg, I have had some success finding answers there. This whole converting video for portable use thing is still pretty new to this forum and pretty peripheral to it's main purpose, I know how frustrating it is to get answers but I feel it's just a matter of time until it becomes more commonplace. I'm sure this wasn't the answer you wanted but maybe it'll point you in the right direction. At the very least it'll bump you up the new posts a bit.

True, portable video conversion is pretty new and not really on the bulls-eye in terms what this sight is about.

But what I'm asking is more about general video conversion, i.e. alternitives to standard upsampling FPS conversion. =P

And filters for Vdub that could help ghosting! Crap like that (assuming they exist!).
