Video Understanding with Language Models
Vision-language models that summarise, search and answer questions about long videos.
Tier Grades
Tier A: Frontier AI labs
feasible
Alibaba, Meta and Shanghai AI Lab release video LLMs.
Tier B: Indonesian AI labs
stretch
Video training data and compute are a stretch; Indonesian video LLM work is not in the sources.
Tier C: Institution units such as ITB
feasible
Fine-tuning a released 7B video LLM (VideoLLaMA3) on local footage is institution-scale.
Tier D: Organisations such as SEMAI (PoT, PoC, PoV)
feasible
CCTV review, broadcast archive search and site monitoring proofs of concept can use released 7B models.
Where this comes from
Tiers: a) frontier AI labs, b) Indonesian AI labs, c) institution units such as ITB, d) organisations such as SEMAI delivering proof of technology, concept and value. Each rationale cites the anchors below.
Anchors
- ComputeVideoLLaMA3 is trained in four stages from vision encoder adaptation to video fine-tuning; compute is not in the abstract.
- DataVideoLLaMA3 favours large high-quality image-text data (scenes, documents, charts) over massive video-text data.
- Team size (proxy)Proxy only (author count of an exemplar paper, not a headcount): 15 authors on VideoLLaMA3.
- Time horizonMonths.
- Shelf-life signalsToken compression for hour-long video (LongVU), Video search products built on video embeddings and video LLMs (TwelveLabs Marengo and Pegasus)
- Pipeline roleTier A releases video LLMs; Tier C adapts them to local video; Tier D applies them to monitoring and archive search.
Where this comes from
Team size is a proxy (author counts of exemplar papers), not a headcount.
