What is long-video-edit?

A long-video editing tool that changes an existing video using text instructions, images, or other reference material while keeping its original length. It can replace people, objects, or visual style while preserving specified actions, audio, and background.

It is for editing long videos, replacing video elements, changing visual style, or modifying footage while retaining other parts of the original.

It avoids rebuilding a long video when only selected elements need to change. It is intended to preserve continuity in the people, settings, objects, and story.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00148	$0.02072
Opus 5.5	$0.00059	$0.00829
Sonnet 5.5	$0.00030	$0.00414
Haiku 4.5	$0.00015	$0.00207

Security

Grade A, and why

long-video-edit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
