6. Limitations

Our study has some limitations, including:

1. We experiment with only videos with English subtitles. However, our method can be extended to include multi-lingual contexts given a strong multilingual language model.

2. The computation and memory requirement of our method is substantial due to its heavy reliance on the large language model, GPT-3.

3. We evaluate Long Story Short with only a single instance of LLM (GPT-3).

Potential Risk. Summarizing the long video context with GPT-3 carries on ethical risks related to the open-ended nature of the language model. GPT-3 may (a) hallucinate fake facts about the content, (b) generate toxic utterances, or (c) implicitly embed social biases into the summary and the answer likelihoods.
