I am sitting on a lot of video. Raw camera files, drone footage, event shoots, years
of it, spread across drives and folders. Storage is full, and the temptation is 
to start deleting or compressing everything to get space back.

Do not. Footage you cannot reshoot is the one thing you cannot get back.

## The rule: raw is sacred

A compressed copy is a derivative. It is good for review, delivery and everyday 
edits. The original is the master. Future you might want a different grade, a different
crop or a format that does not exist yet, and only the original can give you that.

## The process

 1. **Inventory and fingerprint first.** Hash every file so you can prove what you 
    have and later prove nothing changed.
 2. **Two verified copies of every original** before anything is touched, with one 
    on separate hardware.
 3. **Compress a small pilot.** Pick a handful of representative clips, run them through
    the settings you plan to use, and watch them on a real screen. Check motion, shadows,
    skies and text.
 4. **Verify every output.** Duration, frame count, resolution and a hash recorded 
    next to the original’s.
 5. **Only then reclaim space,** and only from material that has both a verified master
    copy and a verified derivative. The raw sources stay on the archive tier. What 
    leaves working storage is the duplicate, not the master.
 6. **Keep a log** of what was compressed, with what settings, and where the originals
    live.

## Where AI helps

Local AI agents do the grind: walking the library, grouping clips, tagging what 
is in them and drafting the compression plan. They suggest. Scripts execute. Nothing
is deleted automatically, and every step leaves a record I can audit.

## The payoff

Back to usable space, a library that is easier to search, and the confidence that
the footage is still there at full quality when a project calls for it. Reclaiming
space is only a win if you can still prove you kept what mattered.
