HyperDeck Review Appears Half-Frame Off¶

NEEDS_REVIEW HYPERDECK

Summary¶

One user reported RT14, camera, and HyperDeck synced, but HyperDeck review footage appeared half a frame off. No confirmed resolution was extracted. Keep this separate from basic HyperDeck IP setup because the root cause may be monitor feed timing, deck latency, sync phase, or review-path assumptions.

The original searchable symptom was: "RT14, cam, and HyperDeck are synced, but review footage will not line up and appears half a frame off."

Symptoms¶

HyperDeck controlled by Flair
RT14, camera, and HyperDeck believed to be synced
Review footage cannot be aligned exactly
Offset appears around half a frame

First Reported¶

2026-03-04 - Marcin Biegunajtys reported half-frame alignment issues during HyperDeck review.

Investigation Checklist¶

Confirm whether HyperDeck records camera sensor output or monitor feed
Check SDI processing/scaler/overlay path latency
Confirm all devices share the intended genlock/reference
Compare recorded camera card vs HyperDeck capture
Test at multiple frame rates before relying on review overlay
Compare review alignment against a hard visual sync event, such as bloop/LED flash, rather than only eyeballing motion
Separate recorded timing from playback/review display timing: the HyperDeck recording may be correct even if the review path is delayed
Document camera model, frame rate, HyperDeck model/firmware, and whether output is progressive/interlaced/psf

"Who has tested HyperDeck and ability to match frames from that footage? I'm synced: RT14, cam, and HyperDeck. But when I review the footage I can't get them lined up, they're half frame off." — Marcin Biegunajtys (2026-03-04)

Working Interpretation¶

This should not yet be treated as a Flair networking/IP problem. The likely investigation path is signal timing:

Verify all devices are genlocked to the same reference.
Confirm whether HyperDeck is recording the clean camera output, a monitor output, or a processed feed.
Check whether any SDI converter, scaler, LUT box, monitor, ATEM, or overlay device sits in the review path.
Compare HyperDeck playback against the camera's internal recording if available.
Repeat at another frame rate to see whether the offset is a fixed time delay or a frame-rate-derived phase issue.

WhatsApp Excerpts¶

2026-03-04 02:56 - ~ Marc Srour: Yes this was the gist of my call with them, they just didn't know the possibility, was all cleared up after I sent them my little VP demo
2026-03-04 04:36 - ~ Marcin Biegunajtys: Ok, so here is one. Who has tested hyperdeck and ability to match frames from that footage? I’m synced: rt14, cam, and hyperdeck. But when I review the footage I can’t get them lined up, they’re half frame off
2026-03-04 04:39 - Ben Myers: Hyperdeck is just recording monitor feed right?
2026-03-04 12:34 - ~ Simon Wakley: Genlock in may NOT genlock the video feed, just the recorded feed. This was the situation with the red once upon a time. Just a thought, I have never tried to get it frame accurate. If you're using one shot, try turning that off, there could be an issue with it.
