Bandersnatch Maker ================== This is a program I wrote on a live stream on the 14th (and 15th) of June 2019. Video link coming soon. You'll need some things. * The movie (complete, with all clips, should be 05:12:14). See https://mehotkhan.github.io/BandersnatchInteractive/ for info on that. * Some data from BandersnatchInteractive. * https://mehotkhan.github.io/BandersnatchInteractive/assets/bandersnatch.js * https://mehotkhan.github.io/BandersnatchInteractive/assets/SegmentMap.js * ffmpeg You'll need to edit the two js files to remove `bandersnatch=` and `SegmentMap=` respectively so they parse as valid json. If you encounter an error about utf-8 bom use dos2unix to fix it. Rename the files to `bandersnatch.json` and `SegmentMap.json`. Open a python interpreter in the same directory as SegmentMap.js. I'd probably recommend 3.7. Paste this in: ```python import json with open("SegmentMap.json") as f: smap = json.load(f) def msToTS(ms): s,ms = divmod(ms,1000) m,s = divmod(s,60) h,m = divmod(m,60) return "{:02d}:{:02d}:{:02d}.{:03d}".format(h,m,s,ms) for segment in smap.values(): ss = "" t = "" if segment["startTimeMs"] > 5000: ss = " -ss " + msToTS(segment["startTimeMs"]-5000) if "endTimeMs" in segment: t = " -t {}".format((segment["endTimeMs"]-segment["startTimeMs"])/1000) print("""ffmpeg{} -i bandersnatch.mkv -ss 5{} {}.mkv 2>/dev/null""".format(ss, t, segment["segment"])) ``` You'll get a bunch of lines to run to generate clips from the full movie. I'd suggest putting these lines into a bash script and leaving it to run for a while. This will take a very long time. While that's going, generate some movies! They're produced in ffmpeg concat format, render them with: ```bash ffmpeg -f concat -i FILENAME.txt -c copy `date +%Y%m%d-%H%M%S.mkv` ```
