Dataset Card for the RealTalk Video Dataset
Thank you for your interest in the RealTalk dataset! RealTalk consists of 692 in-the-wild videos of dyadic (i.e. two person) conversations, curated with the goal of advancing multimodal communication research in computer vision. If you find our dataset useful, please cite

Dataset Details
The dataset contains 692 full-length videos scraped from The Skin Deep, a public YouTube channel that captures long-form, unscripted conversations between diverse indivudals about different facets of the human experience. We also include associated annotations; we detail all files present in the dataset below.
File Overview
General notes:
- All frame numbers are indexed from 0.
- We denote 'p0' as the person on the left side of the video, and 'p1' as the person on the right side.
- denotes the unique 11 digit video ID assigned by YouTube to a specific video.
[0] videos/videos_{xx}.tar
Contains the full-length raw videos that the dataset is created from in shards of 50. Each video is stored at 25 fps in avi
format.
Each video is stored with filename <video_id>.avi
(e.g., 5hxY5Svr2aM.avi
).
[1] audio.tar.gz
Contains audio files extracted from the videos, stored in mp3
format.
[2] asr.tar.gz
Contains ASR outputs of Whisper for each video. Subtitles for video <video_id>.avi
are stored in the file <video_id>.json
as the dictionary
{
'text': <full asr transcript of video>
'segments': <time-stamped ASR segments>
'language': <detected language of video>
}
[3.0] benchmark/train_test_split.json
This json file describes the clips used as the benchmark train/test split in our paper. The file stores the dictionary
{
'train': [list of train samples],
'test': [list of test samples]
}
where each entry in the list is another dictionary with format
{
'id': [video_id, start_frame (inclusive), end_frame (exclusive)],
'speaker': 'p0'|'p1'
'listener': 'p0'|'p1'
'asr': str
}
The ASR of the clip is computed with Whisper.
[3.1] benchmark/embeddings.pkl
Pickle file containing visual embeddings of the listener frames in the training/testing clips, as computed by several pretrained face models implemented in deepface. The file stores a dictionary with format
{
f'{video_id}.{start_frame}.{end_frame}:{
{
<model_name_1>: <array of listener embeddings>,
<model_name_2>: <array of listener embeddings>,
...
}
...
}
[4] annotations.tar.gz
Contains face bounding box and active speaker annotations for every frame of each video. Annotations for video <video_id>.avi
are contained in file <video_id>.json
, which stores a nested dictionary structure:
{str(frame_number):{
'people':{
'p0':{'score': float, 'bbox': array}
'p1':{'score': float, 'bbox': array}
}
'current_speaker': 'p0'|'p1'|None
}
...
}
The 'score' field stores the active speaker score as predicted by TalkNet-ASD; larger positive values indicate a higher probability that the person is speaking. Note also that the 'people' subdictionary may or may not contain the keys 'p0', 'p1', depending on who is visible in the frame.
[5] emoca.tar.gz
Contains EMOCA embeddings for almost all frames in all the videos. The embeddings for<video_id>.avi
are contained in the pickle file <video_id>.pkl
, which has dictionary structure
{
int(frame_number):{
'p0': <embedding dict from EMOCA>,
'p1': <embedding dict from EMOCA>
}
...
}
Note that some frames may be missing embeddings due to occlusions or failures in face detection.
