Timecode Drift

[benmansfield]

Hello,

Anyone else experiencing playback of clips via SMPTE timecode drifting out of sync?

We are having inconsistent issues where clips are sometimes fine, but sometimes behind. Seems almost impossible to recreate issues. The timecode clock on Arena seems to drift out of sync with source and seems to be at its worst with long system uptime.

Latest version of Arena 7.

News to me. What is generating LTC and what is your listening device?
Are your clips Video or AV?

48k Wav files from Ableton, into a Mif4 and then behringer sound cards.

Unchanged system architecture and files from August last year. Other than camera input over NDI rather than BMD SDI capture and software update. All files are video stripped of audio in DXV3.

Yeah, that's actually the same setup I used for a few hologram tours and it was suuuuuper stable for years. Might check to confirm that the signal is dry without any EQ changes. Other than that, It should just work as long as the signal is good and not clipping. (Basic stuff I'm sure you already know lol)

Set warping in Ableton to re-pitch, and make sure aural effects are disabled on the sender machine, also check signal levels, preferably with a sound recorder app where you can also check the waveform is nice square.
