App for smoothing pixelation in a video?

[oldcpu]

Is there a linux app that one can run that will smooth pixelization in a video, especially when video resolution has been previously increased from, say 320x240 to 640x480. . ie. selectively (via an algorithm) smooth the transitions between pixels, when the extra pixels are added?

I recognize that a 320x240 (when increased to 640x480) would look blurry after such a smoothing process, but I am curious if it would look better, and if some applications do a better job than others.

Any one know of any apps that can do such smoothing, or is this simply something that is not feasible?

Hi. You can try VirtualDub (runs fine with Wine) and MSU Deblocking filter. It's slow as hell but it works like a charm. I don't know any Linux native app that can do that.

I'm not much of a wine user (due to my desire to use open source Linux programs, as opposed to Windows programs), but I'll take a look to see if its open source or commercial program. If it is open source, I will give it a try under wine.

Mplayer should be able to help you out here. Study the man page, it has a myriad of switches.
