Timing issues - Decklink Quad - 7 outputs

renderfrog · June 8, 2024, 6:17am

Hey …

We have 7 x 1080p25 screens on a wall at a conference. Lined up. The goal is to run 7 HD video streams (no audio) on them in sync. 7 different videos are rendered out of After Effects. Which together form 1 visual layer.

I loose frame sync over time, little by little - Any good advice on which codec to run for best results? I’ve tried different lossless and also compressed settings in my exporter. I feel the “framedrops” are different with different encoding settings. When I run diag I see the pink line hit the ceiling from time to time on all 7 channels. Maybe the system is just not capable. But I’m so close!

I’m going to try to feed the system Genlock later today, to see if that can line up the playback.

BTW … When I load the producers with clips i use LOAD - and then I trig them using 7 x PLAY. I detect in the log that there are approx. 8 ms span on those 7 commands received by CasperCG well within a frame which at this format would span 40ms - I run companion on a Raspberry PI dedicated to communicate.

Any sugestions on how to keep the 7 videostreams in line sync-wize?

See Caspar logs output below.

All the best

See this issue on GitHub for a possible solution.

Thank you for the directions. Much appreciated.

I’ll take some time to install and test this out.

The idea to load one file, and have it’s content cropped to multiple chips on the board in sync, makes a lot of sense.

Have a nice day.
