avi to HD

[videoconfused]

I have a uncompress avi file that I want to convert into a HD format.
The file is 16:9 but matted so that it fits on 720 x display.

What software should I use convert this avi into HD?
Should I upsample my avi file? And if i do what kind of software can I use to bring back the details that have been blurred by upsampling?

Thanks

lanzsoz resize and some sharpen filter.

Lanczos4Resize is closely related to LanczosResize (correct name: Lanczos3Resize). The latter uses 2*3=6 lobes and the former 2*4=8 lobes to do the resizing. The result is that Lanczos4Resize produces sharper images. Especially usefull when upsizing a clip.

Do I need to use avisynth to use Lanczos4Resize or can i just pick the filter from virtualdub and let it run?

What you're trying to do is pretty easy in AviSynth.


Just create a file called resize.avs with a text editor

Paste In the following 2 lines:

AviSource("c:\folder\myclip.avi")

Lanczos4Resize(1280,720)

Obviously, change the "c:\folder\myclip.avi" to wherever the location of your source file is.


Open up Resize.avs in VirtualDubMod or TMPGEnc (if you want an HD Mpeg2 file)
