I recently had old Super 8 movie film transferred to DVD. Some of the images are grainy. The only way I can describe it is that it looks like we are watching the movies through the flashing twigs of a tree. The company that did the work stated that they were unable to clear the images. They claim that the cause was the process that Kodak used in the mid 70s to process movie film. Is there any software or process that can be used to clean up the images?
Digital Video Repair might use advanced techniques to fix the metadata of the file not its quality and the way is was encoded. For that you need to use tools to modify video. This applications modifies video files, not their content.
