vtt-timeshift
Adjust the timestamps on a .VTT (transcript) to accommodate for cropping the beginning of the source video
Setup
git clone git@github.com:andytuba/vtt-timeshift
cd vtt-timeshift
virtualenv -p python3 .
pip install -r requirements.txtUsage
Put your transcript.vtt file in the vtt_files/ directory
In your terminal:
source bin/activate
python shift_it.py --time 00:05:23.010 vtt_files/transcript.vtt
to timeshift all the captions back 5 minutes, 23.01 seconds. If the video is padded at the beginning, instead of cropped, add a --padded argument, like python shift_it.py --padded --time etc
The timeshifted version of the .vtt file will be placed in the output/ directory (unless you specify a --output path/to/file.vtt).
