Old AviSynth Filter

Their is this old filter for avs 2.0 called simple resize that had a function called warped resize. It could adjust the aspect ration of a video using horizontal and vertical stretch, kind of like a fisheye lens. My tv only does this feature with 480i s-video, composite, and RF input, meaning that the only way I can remove the boarders from 4:3 video in hdmi, component, or vga input is to stretch the video to 16:9. The filter was also released for avisynth 2.5 Alpha but when I tried to use it there were serious chroma issues. I uninstalled avs 2.58 and installed 2.08 to use this old filter and it works without the issues but now I can't use all of my other filters.

Does anyone know of another filter similar to this?

Point us to the source code of the filter and we can try to fix
the chroma issues for you.

EDIT: I found trbarry's filter. I assume that is the one.

Please describe the chroma issues in more details.

Maybe I went too far by saying serious but the chroma gets out of place and it seems like alot of trouble to move it back. I also think the chroma gets distorted with rest of the image but I'm not sure about that. Here is an example image.

avs 2.58


avs 2.08

Looks pretty serious to me!

Even in YUY2 there are errors. I'll try to find some time to look at it.

I have that same readme with the version I downloaded, the error remains. If only I knew how to program I would look at the filter myself. But learning to program is not an option because I can't even get myself to finish reading chapter 3 on this book I have about how to programing in blitzbasic.

And it's all in optimized assembler, which makes it even harder to follow. Tom comments his code well, though.

Assuming it's the same dll I just downloaded from http://avisynth.org/warpenterprises/, have you tried adding:

Code:
converttoyuy2
The filter will fail to work correctly on YV12 clips (as above), but will not produce a warning. The converttoyuy2 advice is in the readme.

Edit: Oops, didn't see neuron2 mentioning YUY2 errors as well! I can't see any...

Yo Dude

http://www.filefactory.com/file/a121...Resize_MOD.zip
EDIT:- Above Link now DEAD.
To download recompiled SimpleResize(),

Contains:-

Original,
FOLDER RecompiledOriginal
FOLDER SSE2_DISABLED
FOLDER SSEMMX_DISABLED

Try them all, suspect SSE2 will be your problem, will not of course be as
fast but the SSE-MMX version may work.

gud luck

EDIT:- Correction, the SSE2_DISABLED May work, else use SSEMMX_DISABLED
which also disabled SSE2.

Fizick is using a modified version of this in his MVTools, might be worth seeing what he changed.

I am so sorry. I feel like an idiot. I didn 't even try changing the color space like davidhorman recommended. I just tried converting to yuy2 before applying the filter and it works. I'm sorry if I caused you guys extra work.
