Mapping Tips/Guides / Ripping from LOSSLESS video
« on: March 26, 2011, 07:26:01 am »
Today I realized the very simple way to rip a map, freely navigating through the demonstration movie.
I'll write what I mean in total.
Open any rerecording emulator to make the process of longplaying easier with showing all secret corners & avoiding faults (cheats & Game Genies also may help). Record the longplay itself in an emulator movie file. Now you shall play it back several times, switching different layers off & dumping it into AVI with any lossless codec you like. The best suggestion from me is Lagarith Lossless Codec (just google it, or i'll post a link).
I think we all know how to record an emulator movie to AVI file, right? If not, I'll explain it, or you may visit this link: http://tasvideos.org/EncodingGuide/VideoDumping.html The case is to dump AVI without filtering, it's clear.
As it was said, you shall dump several AVIs (one per each layer).
After all layers are inside videos, open them in Virtual Dub. Go to Video -> Copy source frame to clipboard for any frames you need & paste 'em to the image editor (say Photoshop). As you can see, in VD you are able to navigate through the movie & observe the map in action.
Sometimes it is necessary to preset the background color for the emulator itself to prevent loss of BG/sprites parts due to similar colors.
VirtualDub is also extremely useful to prepare your vids as Screenshot Autostitcher input by cropping the frame from any side & trimming the whole video into Level-only segments. Just use the Lossless compression again to output (checking no sound is good as well).
Any feedback, suggestions and criticism are necessary.
Little video-demo of how the Screenshot Autostitcher works with such videos:
