Segmentation analysis strategy can be used to deal with long videos:

ffmpeg -i input.mp4 -c copy -segment_time 300 -f segment output_%03d.mp4 - contextual inheritance: in
video_qaIn the mission, byquestions.jsonAdd a prequel (e.g., "In the context of the previous paragraph, why is the protagonist angry?") . - abstract synthesis: Secondary summarization of the summaries generated for each segment with an NLP model (e.g., BERT) preserves global consistency.
- Hardware extensions: Multi-GPU environments are available using the
torch.distributedParallel processing of different segments.
Take care to maintain the integrity of key scenes (e.g., snippets of dialog) when segmenting and avoid cutting them off in the middle.
