How to generate a series of screenshots (not a gallery)

[arcademaster]

Hello everyone, I hope you can help me out with a problem I've having. I'm looking for a tool that can automatically create a batch of screenshots from a video file. I've already googled for it, but I only come up with online tools to create galleries. That's not what I want however, I'm looking to get a batch of individual frames, without any timestamps and preferably with one click. Doesn't even matter if the tool is command line driven, I don't want to have to watch the video for grabbing those screens. The frames should be evenly distributed from throughout the whole video, I'm not looking to capture an animated gif or anything like that.

The tool should work with all common formats (avi, mkv, mp4) and should be able to output untouched png shots in the video's native resolution. Can anyone recommend one? It seems like a simple undertaking (and those gallery tools must be based on such a functionality), but I can't find a tool that does this job. Damn the interwebz and those galleries

Thanks in advance.

Visrtualdub can save a sequence of stills. If you feed it a simple avisynth script then you overcome it's limitations in formats it can load, and you can use the script to decimate the file sending virtualdub just the frames it needs to save. Once you have your first script - which might take ten minutes to write - you can reuse it over and over again just be changing the file path/name.
