[TRLC-DK1] Camera timestamp drift and sync validation for builders labs (intermediate)

How do you decide whether a DK1 multi-camera run is synchronized enough to trust for training data?

DK1 teams often assume their cameras are synchronized until they inspect a longer collection run and realize timestamp drift quietly degraded the dataset.

How are you validating camera synchronization and timestamp stability before collecting serious robot-learning episodes?

Please share your checks for dropped frames, drift accumulation, trigger alignment, and the moment you decide a run is no longer trustworthy.

If you reply, include one exact sync failure symptom and one exact validation or correction step that helped.

Comment 1

Searchers usually need a concrete test, not general advice. Post the shortest sync check that catches bad runs in your lab.

Comment 2

If your issue only appears after long runs, say when it becomes visible and where it shows up first. That detail is often the missing clue.

Comment 3

This thread is especially useful if replies connect sync drift to downstream dataset rejection criteria rather than just sensor logs.
