Replay Interpolator: A tool for large scale time-lapses

Replay interpolator is a tool to render multiple Replay Mod files in a final camera path preserving the in-game time coherence between files.

How to use it:

• Record your replays
• The camera path you want in the first replay remember how long it is, you will need it later
• First, set up a folder in which you will be working
• Inside that folder, put the latest ReplayInterpolator.jar release and a folder called replays
• Put all the replays you want in the replays folder (The replays order of the final time-lapse
• will be in alphabetical order), have a copy of the replays because they may corrupt in the process
• Open the folder in terminal and run with java -jar <name of the jar>
• Insert the camera path duration of earlier
• The program will output a txt file, save it for later, it will be the input for automatically merge the videos
• All the time keyframes have been put and the replays are done for rendering
• Go to minecraft and render all the videos as usual, it will output many videos with a lot of frozen content
• For automatically edit the videos, setup in another folder all the videos, you will need ffmpeg installed, but as you are using replay mod you will have it installed
• Move the out.txt generated to that folder
• Now you have two options:
  • Run the command ffmpeg -f concat -i out.txt out.mp4 on the cmd in the same folder of all the videos with the txt
  • Create another txt file with the command and rename it as a .bat, now you can execute the command by double-clicking the file
