Legacy Workflows

Use this sub-skill when the user works with InternVideo1 or legacy InternVideo checkpoints/tasks from the 2022/2023 code areas.

Read first

• Workflows maps legacy pretraining and downstream subprojects.
• Troubleshooting covers submodules, dependency fragmentation, and old-script pitfalls.

Route by legacy component

User signal	Area
Video masked autoencoder, run_mae_pretraining.py, run_class_finetuning.py	VideoMAE pretraining/finetuning
ViCLIP, video CLIP, InternVid-10M/200M transfer	ViCLIP / Multi-Modalities pretraining
MSR-VTT, DiDeMo, LSMDC, MSVD, VATEX, ActivityNet retrieval	Downstream video-text retrieval
AVA, THUMOS14, ActivityNet localization	Spatial/temporal action localization
VQA, zero-shot action recognition, zero-shot multiple choice	Multi-modalities downstream
UCF/HMDB open-set	Open-set action recognition
VLN-CE	Visual-language navigation

Operating workflow

1. Confirm the user really needs InternVideo1. If they mention InternVideo2/3/Next, route away.
2. Identify the legacy subproject and treat it as self-contained: dependencies and scripts differ across subdirectories.
3. Check for submodule or external repo requirements before running anything.
4. Prefer adapting documented command patterns in a fresh environment instead of mixing dependencies from multiple legacy subprojects.
5. For new research, consider whether a later generation fits better; legacy scripts are useful for reproducing old baselines and downstream tasks.

Boundaries

• Do not import UniFormerV2/Ego-Tasks assumptions unless the submodule/external checkout is present.
• Do not reuse InternVideo2 environment requirements for InternVideo1 without checking the subproject README.
• Do not run legacy downstream scripts until data and checkpoint paths are explicit.
