Exporting videos with Replay Mod

1. Download the ffmpeg binary here. Choose one according to your device’s architecture.
   • (For GitHub builds) Due to the limit of Replay’s command window, you need to rename the executable to a short name, like -> :fr:. Let’s call it <exec_name>.
2. Install an APK Editor from Google Play or everywhere else.
3. Follow the instructions of the app to add the executable to /lib/<device_architecture> folder of the APK. Then build the APK and install it.
   • (Required for a clean install) Install everything needed (Forge, Replay Mod).
4. Now launch Minecraft. We haven’t done yet, so force close it after launching.
5. Find latestlog.txt.
   • Open it and find this line: Added custom env: POJAV_NATIVEDIR=<directory>.
   • Copy the <directory> part.
6. Launch the game again, go to Replay Viewer and load the record you want to export.
7. Follow Replay’s instructions to add keyframes, then (press T show mouse cursor and) click at Render Camera Path.
8. Scroll to the bottom, paste the text you copied in step 5 into the first command line window, then write /<exec_name> (step 1) at the end of the text line.
9. Tap Render and enjoy your video.
