Bibtc is a proof-of-concept project that uses barcode-like burnt-in patterns to embed timecode into video frame images.
It helps synchronize video frames and external per-frame metadata. You can use video timecode to do the same thing, but it's prone to be lost in editing/transcoding. Burnt-in data is more robust to those kinds of desync issues.
-
"Encoder" encodes the current time (
Time.time) using the Flicks 64-bit timecode format and draws barcode patterns on the left edge of the screen. -
"Decoder" decodes the timecode from a video feed.
-
I deployed Encoder to my iPhone X and recorded it using the built-in screen recorder.
-
I copied back the recorded video into the project and tried decoding it. I verified it decodes perfectly synched timecode.
