SYNC HD also features AES/EBU clock I/O, SD and HD video reference in/thru, video program in/out with timecode window inserter, and a host of other features, making it a must have for Pro Tools|HD professionals in commercial music and post-production facilities. Avid SYNC HD attains near sample-accurate lock to serial timecode (through RS-422), LTC, or bi-phase/tach signals, incorporating a high-fidelity, low-jitter master Word Clock that supports operations up to 192 kHz, as well as standard pull-up/pull-down rates for film and video applications. Think of a sync HD as an insurance premium you don't like to pay for it but when you need it your sure glad you got it.Keep even your largest Pro Tools|HD and audio-video productions in total sync. Then you have to align it yourself and you gotta really trust the audio/video sync on your system to do that. I would never mix a film without a SYNC HD because from my experience editors will often try to align audio on their own and then you're stuck with out of sync audio with picture. I mix with and without SYNC HD all the time usually with no problems. So although it is cheaper, you're going to have problems. Most SYNC I/O settings are available directly from within Pro Tools. SYNC I/O with Pro Tools Pro ToolsHD With Pro ToolsHD, SYNC I/O pro-vides highly accurate lock to time code. Would not recommend they are "supported" but in my experience and others, that's a bit a white lie because their software sucks. SYNC I/O can also be used as a stand-alone syn-chronization device. And yes, Blackmagic drivers for ProTools systems suck. What you also want is an application called Catchin' Sync for your iPhone. This can make a difference if your trying to align audio to picture and vice versa. With it, you won't get that variance or jitter. I mean, the newer ProTools will give you sync accurate 1-2 quarter frames.maybe less. I think Mike Thorton did a test with this in a blog post you might want to search for. Without, you get jitter meaning your sync will be variable within a quarter of a frame or so. The Sync X master oscillator runs at 100 MHz, which Avid say is twice as fast as typical JetPLL-based clocks and twice as accurate. You can go without but the edges of your frames won't be locked and perfectly aligned. Lock to sources quickly and accurately - With exceptionally low jitter JetPLL clocking technology, Sync X locks to external sources faster and more accurately than its predecessor, the Pro Tools SYNC HD. That is why there can be a variance of audio-video sync upon each start of play (without a syncHD).īasically, you get much more accurate picture frame edges if you use Tri-sync with a Gen 10 sync generator and a SYNC HD. Some people insist that they are always in perfect sync with a T-Tap, or their desktop monitors, or whatever, but without a SyncHD there is no mechanism by which Pro Tools can see exactly where the video frame edges are in time, and thus cannot accurately place its audio samples to line up. Its a must have for Pro Tools HD professionals in commercial music and post-production facilities. If you will accept audio-video sync that is repeatable only within roughly 1/4 to 1/2 video frame each time playback begins, you can do that without the expense of a syncHD, and frankly without any video card. If you want audio-video sync that is repeatable within a few audio samples each time playback begins, you need a syncHD and video reference to both both it and your video card. I would assume that YOU want to do better than them! If they are always a frame out of sync, they did not properly measure or adjust for the particular video display. I've been in audio studios where they have got the HD Sync yet they are monitoring on a large HD screen which I know to be nearly a frame out anyway so is it really worth the extra 2k for that extra few milliseconds of accuracy? I understand that the HD Sync gives you better frame accuracy but what I can't understand is why a system costing 10k needs another 2k worth of hardware to get it accurate? It's an audio system, surely if should be accurate by default? I've been in audio studios where they have got the HD Sync yet they are monitoring on a large HD screen which I know to be nearly a frame out anyway so is it really worth the extra 2k for that extra few milliseconds of accuracy? I have also been quoted for an Avid Sync HD and Blackmagic Decklink 4k and was wondering what is the exact purpose of is and if it is a requirement? All of our work will be file based (36 DNxHD), mainly 30sec TVCs, radio and possibly the odd bit of longform. We are also getting the S3 controller and dock. We are looking at installing Pro Tools HD Native PCIe + HD Omni system on Windows 10 (i'm a PC guy). I feel like a bit of an outsider as I'm actually a video guy setting up a post house with audio facilities, as yet we have not found ourselves an audio engineer so setting up the audio studio has fallen on me.
