What’s new

  • 22.10.2021 Public beta-version Release
  • 06.10.2021 Alpha-version Release

Key features of the Benchmark Suite

  • The most diverse dataset for alignment of near-duplicate videos:
    • 560 test pairs in each Benchmark with a total duration of ~2 million frames
    • Combinations of 13 frequent distortions obtained due to human/machine video editing and processing
  • Test your method on our Benchmarks:
    • Local time distortions: occur due to video processing (transmitting, compressing with low bitrate etc.)
    • Global time distortions: occur due to video editing
    • Mixed version for versatility testing on both distortion types
  • Find the best method for your near-duplicate video alignment requirements:

To submit your method, please, follow several simple steps in the Algorithm Submission section

You can choose the preset on which the algorithms were tested and sort charts by the algorithm.

NOTE: The same number of test pair on different charts does not mean the same test pair because of sorting the results by algorithm.

Video sequences selection

Content diversity in test sequences is necessary for running algorithms in near-realistic conditions. To provide this diversity the following steps have been undertaken.

We identified two families of cases: processes during which temporary distortions could occur, i.e. video editing, streaming, capturing from different rigidly-connected cameras etc., and content in test videos which is difficult to align, i.e. talking head, recurring events (such as football matches, formula-1 racing), camera on a tripod (small amount of movement) etc. Then, we collected ~2000 videos from Vimeo from each taxonomic category to ensure unbiased video selection and sufficient coverage in terms of semantics and context presented in the video.

Finally, SI/TI features were calculated for each video and for each class we mapped videos to use cases mentioned above.

We chose videos that sufficiently cover SI/TI space and all the identified use cases and got 56 source videos.


Our dataset is constantly updated. Now we have 56 source video sequences with total duration of 195,411 frames. Resolution of all video sequences is 1920×1080. FPS ranges from 16 to 60.

Benchmarks and presets

We decided to divide the problem of video alignment into three logical parts: local time distortions (occurs due to video processing), global time distortions (occurs due to video editing) and mixed time distortions (for versatility testing on both distortion types). Hence, our benchmark suite contains three benchmarks.

Benchmark Time distortions Metric
Local time distortions Drop frames Accuracy(%) of correctly localized time-shifts of initial frames depending on maximum accepted error in frames
Duplicate frames
Freeze frames
Time shift
Global time distortions Fragment insertion F1-score
Drop fragment
Cut the video
Mixed time distortions All time distortions

Metrics are calculated as follows:

Each benchmark consists of four presets for a more precise understanding of the pros and cons of algorithms.

Preset Used distortions
Light Time distortions
Medium geometric Time distortions
Geometric distortions
Medium color Time distortions
Color distortions
Hard All distortions

Distortions and distortion distribution

Distortion type Distortion Description

Submit your algorithm

1. Download input data Download the necessary folders for the benchmark you want to take part in here.
Some important notes:
    A. Each benchmark has train and validation sets
    B. There are 3 folders for each benchmark, containing 4 zip-folders for each preset

2. Apply your algorithm Align videos with your algorithm
You can also send us the code of your method or the executable file and we will run it ourselves.
We expect a specific output of your algorithm. The description and some examples can be found in
downloadable dataset folder. Depending on benchmark, we calculate Accuracy, F1-score,
Precision and Recall.
