Hi there, I have a 800x600 4:3 aspect ratio file that I want to convert to 1280x720, 16:9. The source is incredibly clean so scaling artefacts will be minimal. The question is, how best can I convert the aspect ratios? I could in theory crop the top/bottom of the video, but that is not 100% ideal. So is there a filter/converter out that will produce an effect similar to the 'Just' aspect ratio mode in the Panasonic plasma TVs? This mode basically keeps the centre of the image in roughly the right aspect ratio, but expands the image horizontally the further you get away from the centre. Is there anything out there that can produce a similar effect? It's only a logo animation for a corporate video, so don't worry about me desecrating any actual movie footage or anything!

C:\Program Files\AviSynth25\Docs\english\externalfilters\simpleresize.htm # simpleresize.dll WarpedResize(width, height, hWarp, vWarp) Did you try that one?

Unfortunately, while the SimpleResize function appears to work OK, I get a "CAVISynthStream: System Exception, Access Violation" whenever I use the WarpedResize function. This is extremely irritating as based on the examples, it looks as though it would be perfect.

Acces Violation? Do you have administrator rights on your computer?

Access violation usually means an internal avisynth or plugin failure, so it could be it doesn't like 2.5.7 or your parameters. If your script is correct and it still crashes, tom barry's still around once in a while to check on it.
