5 Ways to Extract Video Frames and Save to Images https://www.raymond.cc/blog/extract-video-frames-to-images-using-vlc-media-player/
Go to the VirtualdubFFMpegPlugin\Plugins32 folder, copy FFInputDriver.vdplugin and the ffdlls folder, then paste both into the VirtualDub\Plugins32 folder.
Run Virtualdub.exe and open the video file by using File > Open or drag and drop. If you wish to save every frame of a small video file to images, skip to step 5.
Go to Video > Frame rate (Ctrl+R) and select Decimate by, then enter a number to save an image every xx number of frames. The No change option at the top will tell you how many frames per second the current video uses. Click OK.
Click on the File menu > Export > Image sequence. Enter the filename to save as, the folder to save into and the output format of BMP, TGA, JPEG or PNG. Then click OK and VirtualDub will begin to process the video.
If the method of extracting every set number of frames is what you are looking for, VirtualDub is by far the best tool to use because it’s incredibly fast to extract the images and much faster than VLC and Free Video to JPG Converter.
An additional option in VirtualDub is setting a specific range inside the video itself so only images between the two points are saved.
