I use my Canon SD1100IS digicam to take pictures and video clips. When I upload to my computer, the folder has a bunch of IMG_nnnn.jpg, MVI_nnnn.AVI and MVI_nnnn.THM files.
The AVI files are in MJPEG format so the size is riduculously large. So I would like to use tools like VirtualDub to combine and compress the AVI files and it helps if all the AVI files have the same prefix and a running sequence number (MVI_1.avi, MVI_2.avi and so on)
How can I rename the AVI files in this fashion but at the same time preserve their original order so that things stay in the correct order when they are combined?
I looked at a few of the file renaming utilities out there but couldn't quite figure out how to do this easily. And if I can save the steps and apply them to a bunch of folders that would save a lot of time.
Thanks for any tips.
