However, I miss the single frame back button and the preview mode does not change until you release the scroll bar. If these two functions were available, this would be the perfect program just to capture frames.
If somebody finds a better (free) program that is specifically made to generate jpg images from a .MOV file please post here.
, the VLC player is probably the best for this. It will play the .MOV video directly from the camera. You can step through the video frame by frame (going forward only, though... have to move the time line slider to back up. But once you get a frame you want to capture, simply select the "Snapshot" item in the "Video" menu and it will save the frame at full 1280x720 resolution. It has default settings to save in your "Pictures" folder (on a Windows PC) in .png format with it's own "VLC" prefix appended to the video name, but you can change the picture file name, location and format by making your selection in the tools/preferences/video menu window (see pic below).
FWIW, the picture below was a screen grab that is standard with a W7 PC. For anything on your screen, you can click on the "snipit" tool icon, then point/drag a box around what you want to capture on your screen, and save what ever is in the box (can be a screen shot from your video player) to where ever you want to store it, with what ever name you give it, in several different formats.
And further, WindowsLiveMovieMaker for W7 has a button to capture the frame from the preview window. This is a handy way to change the frame size of the picture if you want, but it only saves in .png format, and the pixels dimensions of the preview window are not dispayed when you changes its size like WMM did with the Vista verison. These are not usually an issue , but if you try to import a picture in with a video, some editors want the frame size to be exactly the same as the video frame size.
