I've got a video from a dash cam that shows a guy who hit me. I'm trying to catch his license plate. I was able to get screenshots from VLC, but so far nothing I've tried is able to quite get the plate... it's either just a little too small and I can't quite make out the digits, or it's zoomed in too much with the default image viewer for Ubuntu. I tried the Gimp but I can't quite figure out how to carefully zoom in on one section. Maybe there's another tool that is better suited?

You want to be able to do an incremental zoom and then also be able to move around the picture to see the part you want?
You mentioned Ubunto so I hope you don't have to have something working in Linux.
Anyway, I do this sort of thing with photos all the time using PhotoFiltre.

Photofiltre lets me zoom 100%, which isn't in far enough, and 200%, which is too far. I'm trying to find a way to do a "custom" zoom, like 150%, or 137%, or whatever will do the trick.
I've gotten slightly better results with Gimp, but still not optional... it seems to make huge leaps with one click of the wheel.
I should have checked before replying. And you're right - you can't type in the desired amount of zoom in PhotoFiltre as I had thought. Playing around a bit I confirmed if you stick the picture in a PDF file you can type in the amount of magnification followed by the 'Enter' key to zoom in as much as you like. Then you can use the slider bars on the right side and bottom to find the part of the picture you want.
I tested using CutePDF for this. It's free and after opening the picture you 'pretend' you want to print it and after telling it to print you get the option to save it as a PDF file which can then be magnified however you like.
Not sure if this is any help or not.
