Python command line for syncing audio video recordings with YaLTC tracks.

Project description

dualsoundsync

Warning: this is at pre-alpha stage (crappy code ahead)

dualsoundsync is a python command to sync audio and video files shot with dual system sound using a specific hardware timecode generator called the atomicsynchronator. The timecode is called YaLTC for yet another longitudinal time code and should be recorded on a scratch track on each device for the syncing to be performed.

Installation

$ pip install dualsoundsync

Dependencies

Apart from dependencies installed by pip, you'll need a running ffmpeg installation on your PATH.

Usage

The command takes one argument: the folder containing all the files from the camera and from the audio recoder. Those recordings should contain an AUX audio track with encoded YaLTC

$ dualsoundsync <path to rushes folder>

If you want to try it out but don't have yet built your own atomicsynchronator, you can download some sample files with YaLTC from the repo.

Folder and files created

A logfile named out.txt with loguru messages is dumped in the current directory. Inside the rushes_folder those nested subdirectories are created:

  • dualsoundsync/split/ contains all audio split into Right and Left channels and video files split from their audio.
  • dualsoundsync/synced/ contains video files with their synced sound track.
