Could MultiSports Dataset be tranformed to like ucf101-24 dataset or JHMDB dataset?

It could. To get started with Multisports, I would suggest the other repository HIT_ava. The code does not follow the methodology of the published paper but it's simpler and more accurate (at least for UCF and JHMDB), while requiring only person annotations.

Thanks for suggestion.
I have tried convert Multispots to AVA format dataset followinghttps://github.com/Whiffe/Custom-ava-dataset_Custom-Spatio-Temporally-Action-Video-Dataset, but I extracted key frame every five frames. When I test the custom dataset on SlowFast, it was a shit! (and in Multisports some actions just few frames)
So I wanna ask how do you make custom AVA dataset and how many frames should be skipped to extract a keyframe?

[joslefaure]

I did not skip any frame for AVA (ran the code on video data)
For Multisports, I use all the frames provided by the authors of the dataset.

@Eurususu Hello, can you provide the code to convert multisports into ava data format and train in hit_ava?thank you very much
