which is in ms so it doesn’t care about frame rate. including dynamic offset to compensate for Intensity>HDMI, video router, and 65” pix monitor. Sync is rock-steady at any common rate (including 23.98, etc). Without it, I could use the MOTU as my master clock. I have a Rosendahl Nano as my common AES and black burst clock, but that’s only because there’s other syncable stuff in the rack. I’m running Nuendo in a Mac cheese grater, with an Intensity card. Is it really that complicated in PT world? The end game is a system that is frame accurate for synchronising sound effects, foley and dialogue. Is grabbing a Tri-level sync generator the best way to go? Or will splitting the SDI output of the Blackmagic card and feeding it to the Sync HD's video reference input offer similar sync stability?Īll this video stuff is a new world to me, and it is a wee bit daunting so if you have any tips that would be terrific. Could it be a buggy Blackmagic driver that is causing the issues in OSX?Īs far as obtaining stable sync, my brother is mailing me a spare Blackmagic Decklink Extreme card to try which will allow me to jam the whole system together in a number of ways (word clock, LTC, Ref video, etc). Unfortunately the Intensity PCIe card is pretty simple, and doesn't have LTC or Reference I/O at all.

It is a little bit sloppy, changing between plays.Īny idea on what might be going on? Jamming to LTC was a quick roll of the dice on my behalf to perhaps sort out the issues in Quicktime/Safari/Chrome/OSX. Sound to frame sync still seems like a bit of an issue in Pro Tools. They zoom through in a matter of seconds regardless of the video length.

Online video (both Safari and Chrome) and often video files that are launched in Quicktime (work in progress stuff, etc) don't playback at the correct speed.

Video is playing back via a Blackmagic Intensity PCIe card (not the most recent 4k version, but essentially the same layout). It is also tied in with loop sync to my Avid Omni. I am running it with a Sync HD - currently it is clocked to LTC and set to the master in Pro Tools sessions. I am relatively new to the world of video tech, and am having some slightly peculiar issues on my Pro Tools HDX system.
