avisynth questions for psp video 9

[mtb2k]

well i've been reading up on avisynth for a few months off and on. just realized today that file types other than avi can be processed as well. correct?
i'm still confused. i'm using psp video 9 and would simply like to sharpen the video as it is converting. so here is what i do. create myvideo.avs, open with notepad and include the following:

---------------------------------
avisource ("myvideo.avi")
Sharpen(1.0)
---------------------------------

1.) then load the avs in pspvideo9 when i'm ready to convert. is this all i have to do, or is this wrong? do i need to add anything else to that short script?

2.) second question, what about converting and sharpening a wmv or mpeg? do i simply use DirectShowSource in place of avisource, and avisynth processes it just like an avi?
---------------------------------
directshowsource ("myvideo.mpeg")
Sharpen(1.0)
---------------------------------

3.) is there a method of reducing the blur that the lcd produces with some videos?

Unless you want to do more than just sharpen, no.

Yep.

3.) is there a method of reducing the blur that the lcd produces with some videos?
Well, that depends on what causes the blur. If it's blurred because the video is smaller than the PSP's display and the scaler used by the PSP is crap you could use LanczosResize (or Blackman or one of the Spline or Gaussian scalers in AviSynth) to scale the video to the PSP's native resolution before sharpening.

If that's not what causes the blurs - have you checked if the video isn't just inherently blurry by playing the file on your PC? An overall lack of bitrate will, of course, also blur the image.

np: Apparat - Over And Over (Walls)

i think the blurring is caused by the response time of the lcd in the psp, which is a bit slow. i thought i found some info in the past about how to minimize blur from a slow lcd but can't remember details
