VirtualDub MSU OldCinema Filter 2.0

Algorithm: Dr. Dmitriy Vatolin
Implementation: Vladimir Popov, Nikolai Trunichkin

This filter is intended to achieve an “Old cinema” effect. You can vary color correction algorithm and add various artifacts, so video looks like “chronicle”.

Features

Several color correction types
Vertical Stripes
Small and large noise
Emulsion exfoliation effect

Changes in version 2.0

Improved vertical scratch generation algorithm
Added large spots generation algotithm
Added new color correction algorithms
Improved spots: black and white, and various sizes
Added image flicking

Settings

Filter has simple and advanced settings:

Filter supports VirtualDub job control, so it is usable in AviSynth. Example:

            LoadVirtualDubPlugin("..\VirtualDub\plugins\MSU Old cinema.vdf","Old_cinema", 0)
clip=AVISource("D:\work\video\film.avi", false, "RGB24")
return clip.ConvertToRGB32.Old_cinema(247, 223, 181, 0, 1, 10, 10, 15, 70, 3, 20, 5, 50, 150, 0, 1, 100)

          

Filter parameters

Filter parameters:

16. Color correction
No Changes - there is no color correction
Manual Linear - linear transform from color to black&white video
1. Red - Correct red color
2. Green - Correct green color
3. Blue - Correction Blue parameter
Yellow Shift - colors are faded to yellow
Blue Shift - colors are faded to blue
Fade effect
4. True/False activate effect transfer from “Color cinema” to “Old cinema”
5. If True then we transfer from “Color cinema” to “Old cinema”, if False then transfer from “Old cinema” to “Color cinema”
6. Start frame number
7. Duration of transfer (in frames)
Roller`s track
8. Number of tracks
9. Clarity tracks
Scratch settings
10. Number of scratches
11. Probability of scratch
12. How many frames scratch will be shown
13. Clearness of scratch
17. Scratch thickness
Border fade
14. Shape of ellipse. If this parameter is greater, ellipse transforms into rectangle
15. Fade sharpness. If this parameter is greater, pixels outside ellipse fade less
Show noise - display large noise
Screen shivering
Effect light lamp - colours are faded at the image border
Random noise on screen - display small noise
Flicking - light intensity is changes randomly
Big noise - display large spots

Examples

Let’s consider results of the filter on a test sequence “Foreman”.

source frame from "Foreman"sequence

after MSU Old Cinema, use "Yellow shift" color correction

The next example demonstrates the usage of the “Real old cinema” preset. Certainly, you can adjust the amount of noise, spot, scratches and other types of artifacts regardless of the preset as every film features its own adjustments.
