av-sync's Introduction

AVSnap

This repository contains demo code for the paper Dynamic Temporal Alignment of Speech to Lips (Tavi Halperin, Ariel Efrat, and Shmuel Peleg). The repository reuses code from the demo for the audio-to-video synchronisation network (SyncNet).

The model and code can be used for research purposes under Creative Commons Attribution License. Please cite the papers below if you make use of the software.

Prerequisites

The following packages are required:

pytorch (0.4.0)
numpy (1.14.3)
scipy (1.0.1)
python_speech_features (0.6)
cuda (8.0)
ffmpeg (3.4.2)
tensorflow (1.2, 1.4)
scikit-image (0.14,1)
imageio (2.2.0)

The demo has been tested with the package versions shown above, but may also work on other versions.

Demo

First, download face detection and SyncNet models

sh download_model.sh

To run the demo, aligning audio from video2.avi to video from video1.avi

python run_pipeline.py data/video1.avi
python run_pipeline.py data/video2.avi
python align_audio.py data/video1.avi data/video2.avi --modality=all

The alignment will be computed based on both video and audio of the input videos. You can use only one of the modalities by changing the flag --modality to one of va/aa/av/vv, the first letter indicates which modality is used from the first input, and the last letter indicates which is used from the second.

Outputs:

data/out/video1_video2/modality_all.mp4
