Software to convert video to picture or video to .JPG to avoid taking screenshots by hand for many videos
I want an application to convert videos to a series of images.
- I need to be able to do conversion from videos to
.jpgand.pngand other picture format output files. - I need to be able to set the number of frames used for conversion
- I need to be able to specify the quality of the output images
- I need to be able to make on-the-fly adjustments.
Is there anything that will work out of the box to do what I need?

The command line tool ffmpeg can disassemble a video in individual image files, and also can reassemble image files into a video. ffmpeg has a myriad of options allowing for a very high level of control, but that comes at a price of complexity and some learning curve.
For example, the following command will output an image every second:
ffmpeg -i input.mp4 -vf fps=1 out%d.png
The extension you provide, determines the file format you export. You can, if needed, provide extra options to control the graphical output yourself (i.e. change compression level, resolution, etc.)
Resulting images may then be further batch processed using Imagemagicks convert. For batch processing, you may prefer to use mogrify, which overwrites the original image file.
