Scanning Movies - The Workflow



Flow Flow
The scanner automatically scans the film and saves images of ten frames in separate files. This is my own software coded in C++ (MFC). There are a lot of Internet resources on how to code TWAIN drivers. The individual frames are extracted in batch processing of the filmstrip images. The software looks for the perforation holes and cuts out the frames.

I usually correct one image from a scene in Adobe Photoshop (http://www.adobe.com/) for contrast, exposure, sharpening, white balance, noise reduction etc. The entire scene is batch processed using the same settings. The individual frames are merged to an .avi file in Antechnius Animation Professional (http://www.c-point.com/index.html)
Flow
VirtualDub (http://www.virtualdub.org/) with the plugin DeShaker (http://www.guthspot.se/video/deshaker.htm) is used to run post processing image stabilization. This really makes a difference on shaky amateur movies. Finally the .avi file is compressed and saved on a DVD. There are many programs that can handle this.


Rescuing Low Quality Footage

This is two examples of scenes that need some postprocessing. Tone mapping, color correction and sharpening is necessary. Some bad scenes can be surprisingly well rescued. It is necessary to work with uncompressed images to do this. All detail and bit depth that you can get from the scanning helps.
