Crop() problem on Windows 7

[Mystery Keeper]

I'm trying to use AviSynth 2.58 under Windows 7. But while it renders error clips, it can't render the clip from actually working script. I tried commenting the whole script and uncommenting line by line. The source of problem is crop(). Whether I remove it completely from script, it renders alright. Update: Error happens if I use crop() with negative values. Positive values work.

I cannot reproduce that. I tried exactly your script (however without colormatrix) - loaded in VirtualDub, it shows up and plays correctly.
Avisynth 2.5.8.MT 32bit, Win7 HP 64bit.

I wish people would stop posting images of textual information.

Just swipe the text and paste it as text. Then I can swipe the text and diagnose it without the risk of transcription errors.

Having upgraded my PC, reinstalled Win7, and not having this problem anymore. Still, something must have caused it.

If you would have put converttorgb() at the end of the script it would have played. YV12 video is what the encoders want, so converttorgb() is useful just for seeing the results and checking if all is good.
