Hello,

I have been searching for a filter such as this one:
http://www.dcs.gla.ac.uk/~jhw/filmy/

He claims he is porting it over to AviSynth. Is there anyone that is willing to port it over? It would be wonderful if someone could!

Regards,
Josh

Big noise for what?

If one wants to do the same steps as he is showing, simply ;) re-build it in Avisynth. Plugins for every single step are available, or can be scripted rather easily. That's not the problem.

However the guy seems to underestimate the overall processing power needed for video. From the guts, that processing smells like mfps (<< 1fps).

Plus, if one has fiddled a processing chain that seems to work even so nice on a single picture, the big surprise often arises when the processing is applied to series of frames, when it reveals that the result is temporal inhomogenous.

interesting demo images.

i think a few steps could be removed from that process.

plus, manao's RGBlut can take curves files from photoshop. make a nice custom curve, do an unsharp-mask (not too hard, like in that page), and overlay a blurred version of the original, and you've got yourself a purty film-look.

grain should be minimal - after all a good transfer from 35mm to SD won't show much grain at all (if any).

the best way to get a filmlook is to simply light your scenes well and have an eye for composition. deinterlacing helps, too :)

I've made such a filter for VirtualDub that can do some things demonstrated on the site you've mentioned.

You can apply curves to the video and the filter it's quite fast, although improvements could be made.
The only problem until now is the user interface - I'm still trying to get a curve-edit with mouse ability to the filter, but on the other side you can import the curves from Photoshop.

If you want to take a look at my filter you can find it here:

I think there is a way to use VirtualDub filters within AVISynth

Hi,

I agree with Mug Funky and Didee. First, I don't think these steps, especially the overdone contrast, grain, and sharpening will look good on video. Second, the "after" doesn't look better than the "before" in my opinion. Finally, a few simple steps can be done to make video look like film, but its subjective.

And I suggest anyone interested in more ideas for how to achieve video --> film look check out the forums at DVInfo.net (http://www.dvinfo.net/conf/).

But, It seems to me the hardest thing to do, as Mug Funky alluded to is getting the light and contrast right, which may be inhibited by consumer equipment (although they are getting better and better these days).

Sincerely,

Dali

The reason I ask if someone will port it, is because I believe (could be totally wrong) the project is abandoned. I've heard of too many things like this before and all turn out abandoned.
