The demo below was captured using a Vivitar 8mm s8mm projector with the shutter and gate removed, and a tachometer installed running at 9 fps. The camera used was a Panasonic chip camera attached to a macro lens, capturing at a rate of 60 fps.
This kind of setup will provide extremely clear and sharp captures of films, though similar results can be achieved projecting onto a matte white card or matte photo paper and a good HD camcorder capable of 50i/60i or greater capture rates.
The following Avisynth functions were added to a template file "proc.avt" for post prcessing:
#__post__# Crop(268, 8, -244, -14)
#__post__# FlipVertical()
#__post__# Tweak(startHue=100, endHue=140, sat=0.62, coring=false)
#__post__# LanczosResize(960,720)
#__post__# AddBorders(160,0,160,0)
#__post__# ChangeFPS(59.94)
The Crop function will remove all the surrounding black. FlipVertical is obvious. The Tweak function will tone down the brightness of the orange shirt. The resize brings the cropped video back to a standard 4:3 aspect ration and resolution. AddBorders adds black to the left and right sides bringing the video to an HD resolution of 1280x720. The ChangeFPS function duplicates enough frames each second to bring the 18 fps film to the HD standard of 59.94 fps for 1280x720 video.
The first portion of the video is the raw captured video.
The second portion is the result of using Cine X-Tractor (XtractorCL.exe). The command line used to process the raw .mts camera file was:
XtractorCL.exe "d:\video\01.mts" -f 18 -e 2 -p 2 -t "proc.avt"
"-f" tells Cine X-Tractor that the original film frame rate is 18 fps. "-e 2" uses auto exposure for the analysis phase. "-p 2" tells Cine X-Tractor to use the post processing entries in the pre/post processing template file. "-t proc.avt" is the template file to use.
Running this command produced an Avisynth script called 01.avs which when opened in VirtualDub produced the second portion of the demo video.
The third portion of the demo was produced using the Avisynth plugin "InterFrame". This plugin will use motion interpolation to create higher frame rate video. After installing this plugin and replacing ChangeFPS(59.94) in the 01.avs script with...
InterFrame(newnum=60000,newdem=1001)
...and opening the modified 01.avs script in VirtualDub, the resulting was smooth 59.94 fps video derived from the original 18 fps film.
