CondensedMovies Dataset

The dataset consists of 3K+ movies, 30K+ professionally captioned clips, 1K+ video hours, 400K+ facetracks & precomputed features from 6 different modalities.

Installation

Requirements:

• Storage
  • 20GB for features (required for baseline experiments)
  • 10GB for facetracks
  • 250GB for videos
• Libraries
  • ffmpeg (for video download)
  • youtube-dl (for video download)
  • pandas, numpy
  • python 3.6+

Prepare Data

1. Navigate to directory cd CondensedMovies/data_prep/
2. Edit configuration file config.json to download desired subsets of the dataset and their destination.
3. If downloading the source videos (src: true), you can edit youtube-dl.conf for desired resolution, subtitles etc. Please see youtube-dl for more info
4. Run python download.py

If you have trouble downloading the source videos or features (due to geographical restrictions or otherwise), please contact me.

Video-Text Retrieval

Baseline (Mixture of Expert Embeddings)

Edit data_dir and save_dir in configs/moe.json for the experiments.

1. python train.py configs/moe.json
2. python test.py --resume $SAVED_EXP_DIR/model_best.pth

Visualisation

Run python visualise_face_tracks.py with the appropriate arguments to visualise face tracks for a given videoID (requires facetracks and source videos downloaded).

TODO:

• youtube download script
• missing videos check
• precomputed features download script
• facetrack visualisation
• dataloader
• video-text retrieval baselines
• intra-movie baselines + char module
• release fixed_seg features

FAQ

Why did some of the source videos fail to download?

This is most likely due to geographical restrictions on the videos, email me at maxbain@robots.ox.ac.uk and I can help.

The precomputed features are averaged over the temporal dimension, will you release the original features?

This is to save space, original features in total are ~1TB, contact me to arrange download of this.

I think clip X is incorrectly identified as being from movie Y, what do do?

Please let me know any movie identification mistakes and I'll correct it ASAP.
