# Video Temporal Grounding on ActivityNet (R1 Metrics) Source: [Video Temporal Grounding on ActivityNet (R1 Metrics)]() Collection index: [llms.txt]() Data updated: 2026-06-09T10:34:18.879Z Evaluation of Video Temporal Grounding performance on the ActivityNet dataset, focusing specifically on Recall metrics at IoU thresholds (R1@0.3, R1@0.5, R1@0.7). 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 Temporal Grounding | | Dataset (including any stated split) | ActivityNet | | Metric | R1@0.5 | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 16 of 16 | | 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 - [R1@0.5](): Higher is better; unit: PERCENT. - [R1@0.3](): Higher is better; unit: PERCENT. - [R1@0.7](): Higher is better; unit: PERCENT. ## Recorded results | Method | R1@0.5 | Result date | Report paper | | --- | --- | --- | --- | | TaRO | 40.6 | Not recorded | 6a279e5990966ade919bfa22 | | TaRO | 39.8 | Not recorded | 6a279e5990966ade919bfa22 | | Time-R1 | 39 | Not recorded | 6a279e5990966ade919bfa22 | | TaRO | 32.7 | Not recorded | 6a279e5990966ade919bfa22 | | VideoChat-R1.5 | 32.3 | Not recorded | 6a279e5990966ade919bfa22 | | Qwen3-VL-8B-Instruct | 31.7 | Not recorded | 6a279e5990966ade919bfa22 | | Qwen3-VL-8B-Think | 30.5 | Not recorded | 6a279e5990966ade919bfa22 | | HawkEye | 29.3 | Not recorded | 6a279e5990966ade919bfa22 | | VTimeLLM | 27.8 | Not recorded | 6a279e5990966ade919bfa22 | | Time-R1 | 26 | Not recorded | 6a279e5990966ade919bfa22 | | UniTime | 22.8 | Not recorded | 6a279e5990966ade919bfa22 | | ChatVTG | 22.5 | Not recorded | 6a279e5990966ade919bfa22 | | TimeChat | 20.2 | Not recorded | 6a279e5990966ade919bfa22 | | TimeSuite | 16.6 | Not recorded | 6a279e5990966ade919bfa22 | | Qwen2.5-VL-3B-Instruct | 15.2 | Not recorded | 6a279e5990966ade919bfa22 | | Qwen2.5-VL-7B-Instruct | 13.6 | Not recorded | 6a279e5990966ade919bfa22 | ### TaRO R1@0.5: 40.6.
