The part everyone misses: watching a clip is not saving it. Sweep until the moving dot sits in the framed box, then press X (PS5) / E (PC) while the CRTV is still up. Only video recordings (Zoe, Richard, a building, a date) count toward the 18 - creature static does not. Progress on saved video channels carries between playthroughs.

2Decision Points

SituationWhat to do
New hiss, no pictureCreature signal. Save only if you need the silhouette - it does not add to the 18.
Marker on the dial + a clip startsVideo signal. Stop and lock it immediately - some are missable in that chapter beat.
Radio or tuner on a tableInteract with the radio first, then fine-tune the CRTV. This is how the pharmacy and later rooms work.
A building or street on the glassTreat it as direction + rough distance, then peek with R1 + right stick. It is not a minimap pin.
Several marks at oncePage one enemy at a time - "which frequency is which monster" is the awkward part.

3Early Video Signals in Story Order

Channel numbers are approximate - use the marker on the frequency band, then complete the lock minigame.

After the first two hotel clips: check the CRTV again when you re-enter Shorefront - the next video often shows 2A West Shore Lane (alley left of Ferguson's, house on the right).
There are 18 video recordings total. Hunt a new marker whenever a chapter title card drops or you enter a named interior with a radio.
