I have converted a video clip into a series of pictures in .PNG-format using ffmpeg. (As far as I know the PNG-format is a lossless format?).
Now I want do some changes in each of these pictures in a smooth and efficient way. An example would be to remove a black frame which is situated on the same position in each picture. This could be done manually, but if the series consists of 100 or more pictures this would be a very boring and time-consuming job..
Basically I'm looking for an editor-program with scripting capabilities (or similar) so that I can script the remove operation and then apply it to one or more of the pictures in a batch job.
If the program was able to expand the picture to its original size after the remove-job was done it would be excellent.
Does anyone know or have any experience with Linux-programs which could do this types of tasks ?
Currently I'm running Ubuntu Linux 10.04 64-bit.
