Q: It says I don't have any decks, what do I do?
A: You can initialize a deck by running castle init <name> or get a pre-existing one by running castle get-deck <id> folder
Q: Why does it say "nothing to do"?
A: You either forgot to install pillow ffmpeg and mido, or you said no to all the prompts.
Q: What does quantizing mean?
A: Quantizing automatically makes your image use less data, but it may look worse if the value is too low.
Q: What does it mean by "frame split"?
A: It divides your frames by the value you input. For example, if you enter "2", you will get half the frames.
Q: What does "Memory Access Out of Bounds" mean?
A: That means the image or MIDI file you input caused your deck to exceed castle's 10MB limit. You need to quantize it or use less frames.
Q: Why does it say I don't have any decks?
A: You are probably running the command while in a different directory. cd into where your deck is (usually ~/decks)
