The next feature on the list is a built-in video slicer. It’s not a guarantee but Unity has a video player that can seek and can transmit camera data to images, so what could possibly go wrong? Ha… hah… worst case scenario, I’ll dig out Ffmpeg and see what else can be done.
Thankfully Blender is very easy to convert videos in. You just pick the Video Editing layout on startup and drop a supported video format into the sequencer, then mess with one of the tabs to determine Start Frame, end frame, Framerate, and skip rate. Exporting to images is the default there. If that’s not going to work, other video editing software will usually support this feature as well.
