VLA Data Augmentation (Veo 3.1)

Synthetic video samples for vision-language-action (VLA) data augmentation: 8s clips generated with Veo 3.1 on Vertex AI, with per-clip frames and prompt metadata.

Dataset summary

• Model: veo-3.1-generate-001
• Duration: 8 seconds per clip, 16:9, no audio
• Content: Multi-scene prompts (meetings, care, logistics, office, etc.), 6 clips per prompt
• Structure: Each batch has raw/ (mp4), frames/ (8 frames per clip), meta/ (prompts and run records)

Prompts (11 planned)

ID	Slug	Description
p01	management_meeting_entry	Six leaders enter and take seats in conference room
p02	secretary_then_executives	Secretary prepares docs and leaves; six executives enter and sit
p03–p06, p08–p09, p11	(see RUN_PLAN)	Home care, hospital, construction, logistics, patrol, office, repair shop
p07	warehouse_pallet_wrapping	Day 6 补跑：原 prompt 触发 API 无视频返回，改用软化版一次跑通。见下。
p10	chainstore_manager_restock	Day 5：原 prompt 曾在 clip04 无视频返回；用原 prompt 重试后 batch3 一次 6 段成功。见下。

p07 补跑（Day 6）：原句含 “stretch wrap”“secures” 等词时两次均 no generated video in response。实际使用 prompt（runs/day06/p07_warehouse_pallet_wrapping/batch2/meta/README.md）：

In a warehouse, a worker moves boxes from a conveyor belt onto a pallet and arranges them neatly. Gender and skin color must be clearly visible.

完整原因与对照见 RUN_PLAN_5D_11PROMPTS_X6.md §10。

p10（Day 5）：原 prompt（“chain store”“checks the work schedule”…）在 batch1 的 clip04 曾返回无视频。用原 prompt 重试，batch3 一次 6 段成功，seed 51013–51018，作为 p10 正式批次。原 prompt 与 RUN_PLAN §3 一致；runs/day05/p10_chainstore_manager_restock/batch3/meta/README.md。batch2 为软化版备用（seed 51007–51012）。
