To make new movies look like from 1920

[AsTimeGoesBy]

Hi, watching a new video from Anastacia i had the idea to make some of my encodings look old just the same.
Some common aspects are:
1.) they seem to be B/W-colored ;)
2.) they miss some sharpness but have rahter strong contrast
3.) sometimes they lose brightness on outer areas of the frame
4.) they have vertically 'running' scratches
5.) the playback doesn't leave a fluid impression
6.) ...?

So what can i do now to make a new movie look this old?
1.) greyscale()
2.) blur(), spatialsoften() i guess!?
3.) overlay() with a round mask could do this.
4.) A 'vertical' scratch (anti-)filer. That will be a problem, does there exist any i don't know?
5.) Would it help here to insert/duplicate random frames to get 30fps (from 25fps)?
Let us say for each 25 frames duplicating frame #12 two times and frame #25 three times. Is there any way to do this with a function by passing a frame-counting variable and applying modulo operation? And how to return the enlarged frame section then?
A random insertion position would be look better maybe but i have no idea how to ensure exactly 30fps.


So what do you think, is such a old-style-filtering realizable or should i better go on simply turning down the color-saturation of my TV set?

4.) Afaik the newer ffdshow versions can do this, no?

Just record to tape, and wait 80 years. :D

Most of it can be done with ffdshow in realtime :)
Just do the following:
- desaturate
- colorize (to get that sephia effect)
- play witht the noise paramaters to add scratches / lines and 'standard'luminance noise

This is what I came up (quick and dirty):
Original (http://www.stud.uni-goettingen.de/~s304280/D9/original.avi)
1920-style (http://www.stud.uni-goettingen.de/~s304280/D9/1920.avi)

Damn, why didn't i know this already earlier...!?

That's so cool, an old-style-post-processing filter. :) :) :)
'5th Element' looks like a new 'Flash Gordon' episode and 'Troy' appears as 'Ben Hur' revival. :)

Sorry, but i must immediately go on browsing my movie folders. - Thanks for that great advice!

search the film-look-thread for "gramama", my gradient-mask-maker-plug-in

5.) the playback doesn't leave a fluid impression
I believe that back then typical frame rates were 11fps, depending on how consistently / accurately the camera man could trun the crank on the shutter.

Yeah, try messing around with framerate conversions - try converting to 12fps then back to 25, or something screwy.

Thanks for the useful hints. Since the new fddshow does a good part of the work, i myself will try to tweak the playback-speed impression.

But i have had the problem that it wasn't able to use ffdshow as filter for AviSynth. Althought i even have defined a preset like written in that ffdshow thread (http://forum.doom9.org/showthread.php?s=&threadid=85447) i haven't got a BW video stream in VirtualDub... :(

Maybe i was too enthusiastic... ;) - I will re-install all an retry it the next days again.

Yes, you do all this efford to make new film look old, while I am doing all this efford to make old films look brandnew:D :D :D

But I understand, of cource. The 1920 look is awesome and comic.:p
