# Video Action Recognition on SS v2 (ACC@1) Source: [Video Action Recognition on SS v2 (ACC@1)]() Collection index: [llms.txt]() Data updated: 2026-05-13T07:57:43.513Z Evaluation of Video Action Recognition performance on the Something-Something v2 (SS v2) dataset, specifically reporting Top-1 Accuracy (ACC@1). A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Video Action Recognition | | Dataset (including any stated split) | SS v2 | | Metric | Top-1 Accuracy (SS v2) | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 26 of 26 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Top-1 Accuracy (SS v2)](): Higher is better; unit: PERCENT. ## Recorded results | Method | Top-1 Accuracy (SS v2) | Result date | Report paper | | --- | --- | --- | --- | | VideoMAE V2 | 76.8 | Not recorded | 68fa7b991e209131cea89646 | | V-JEPA2-L | 73.7 | Not recorded | 69b39a370636e5bf4afbccff | | V-JEPA-2 | 73.7 | Not recorded | 6a016288dbc836b87d82305a | | LookWhen (70% sparse) | 72 | Not recorded | 6a016288dbc836b87d82305a | | VideoMAEv2 | 71.2 | Not recorded | 6a016288dbc836b87d82305a | | VideoMamba-M800e | 71 | Not recorded | 6a016288dbc836b87d82305a | | UMT-B800e | 70.8 | Not recorded | 6a016288dbc836b87d82305a | | VideoMAE | 70.8 | Not recorded | 6a016288dbc836b87d82305a | | VideoMAE + RLT (τ=0.1) | 70.2 | Not recorded | 6a016288dbc836b87d82305a | | InternVideo2 | 69.7 | Not recorded | 6a016288dbc836b87d82305a | | VideoMAE + ToMe (r=64) | 69.7 | Not recorded | 6a016288dbc836b87d82305a | | VideoMAE + vid-TLDR | 69.6 | Not recorded | 6a016288dbc836b87d82305a | | VideoMambaPro | 69.4 | Not recorded | 6a016288dbc836b87d82305a | | LookWhen (90% sparse) | 69.3 | Not recorded | 6a016288dbc836b87d82305a | | OmniStream | 68.5 | Not recorded | 69b39a370636e5bf4afbccff | | VideoMAE + LITE (K=0.3) | 68.3 | Not recorded | 6a016288dbc836b87d82305a | | VideoSwin + STTS | 68.1 | Not recorded | 6a016288dbc836b87d82305a | | NoFrame | 62.7 | Not recorded | 68fa7b991e209131cea89646 | | TSM | 61.7 | Not recorded | 68fa7b991e209131cea89646 | | DINOv3-L | 54 | Not recorded | 69b39a370636e5bf4afbccff | | MoTIF-ST | 41.9 | Not recorded | 68fa7b991e209131cea89646 | | MoTIF | 40.4 | Not recorded | 68fa7b991e209131cea89646 | | MoTIF | 37.3 | Not recorded | 68fa7b991e209131cea89646 | | Global CBM | 33.6 | Not recorded | 68fa7b991e209131cea89646 | | MoTIF | 25.8 | Not recorded | 68fa7b991e209131cea89646 | | Zero-shot | 2.2 | Not recorded | 68fa7b991e209131cea89646 | ### VideoMAE V2 Top-1 Accuracy (SS v2): 76.8.
