Video Understanding
Qwen3-VL delivers exceptional video understanding capabilities, including improved video OCR, long video comprehension, and temporal grounding. The model can process hours of video content with full recall and second-level indexing.Capabilities
Video OCR
- Text Extraction: Read text appearing in video frames
- Subtitle Recognition: Extract and transcribe on-screen text
- Motion Tolerance: Handle moving cameras and text
- Multi-language: OCR support for 32 languages in video
Long Video Understanding
- Extended Context: Native 256K context, expandable to 1M tokens
- Full Recall: Remember details from hours of video
- Second-level Indexing: Locate specific moments precisely
- Temporal Coherence: Track events and changes across time
Video Grounding
- Temporal Localization: Find when events occur in video
- Object Tracking: Follow objects across frames
- Event Detection: Identify specific actions and occurrences
- Timestamp Generation: Provide precise time markers
How It Works
Interleaved-MRoPE Architecture
Qwen3-VL uses Interleaved-MRoPE (Multi-Resolution Rope) for video understanding:- Full-frequency Allocation: Optimized positional embeddings for time, width, and height
- Long-horizon Reasoning: Enhanced capability for extended video sequences
- Temporal Modeling: Better understanding of events over time
Text-Timestamp Alignment
The model features precise timestamp-grounded event localization:- Move beyond traditional temporal RoPE
- Link descriptions to exact video moments
- Enable frame-accurate temporal queries
