All videos were encoded with VirtualDub,
together with the free version of DivX codec.

VirtualDub takes continuously numbered image files as input,
which then can be processed like any other video file.

Since my cam (i think most others do this too) only records 2000 images into one folder,
then starts numbering files from 1 in another folder again,
i had to do some serious renaming (I have timelapses with over 12.000 images).

For this, I coded a small tool, which renames files.
It starts in its current directory, gathering ALL files in ALL subdirectories.
After scanning, it sorts the files by FULL PATH (my cam numbers its folders too),
Then renames/moves all files into its current directory, correctly numbered from 1 to X.

You may get it here. Right click-> Save as...

Just copy it into the directory you want to renumber files in, and start it with:
java -jar renamer.jar 5
The 5 is for total number length: 00001, 00002 etc...
BE SURE TO START IT FROM THE RIGHT DIRECTORY! Every file within this folder, and below, will be renamed!

You might need to install Java, which is available here. (JRE)
