OT: Sony LMD-2020 sync
Anyone else FORCED to use these crappy LMD monitor from Sony? I’ve noticed after two days of cutting that they are out of sync. There is a noticible delay in picture comming out of my Blackmagic card. SDI, Component, Composite – all of them have a slight studer. In FCP whn you scrub, you can see thee delay!
Anyone else have this problem?
FYI this is happening on all 4 edit bays. All using Blackmagic Deck Link Extreme Cards and the Sony LMD2020 monitors.

Have you played with the Playback Offset at all? that’s what it’s there for, to put audio and video back in sync when there’s an offset.

did you post this in the BlackMagic forum? Not sure how many people in this forum use BM products, I don’t.

I would have to agree with Walter. We use the very same monitors and I don’t see any problems like that except the slow screen refresh of the monitor.

I hate to disagree with Walter on this, but I have seen the delays in the LDM series, and my clients who have them want to kill me. I most recently replaced the extremely terrible LDM-1410 (the bottom of the line model) that I had on a simple VHS dub rack, because everyone thought that the job
was out of sync (of course, it looked fine in their edit rooms, using FCP/AJA gear with Sony SDM-P234b monitors, and Sony PVM20M4U’s. I replaced
the LDM-1410 with a cheapo Sony PVM-14L1, and the problem was gone.On top of this, the LDM-232 is a real piece of crap at $6000. The image quality on modern (2006) LCD consumer monitors are far superior (like Sony home LCD monitors). For pro applications (aside from the usual Apple Cinema, Dell 2405, HP 2335 and Sony SDM 234), the Panasonic BT-LH1700 is a good choice (damn, do I miss the PVM-20L5/1). I will NEVER use a LDM series ever again.

nothing to disagree with. I just suggested the Playback Offset as a solution, but obviously this doesn’t sound like it works.
Haven’t heard anything good about the Sony Pro LCD monitor series and this thread certainly reinforces the information I’ve been seeing. I’m soooo glad I got the extra PVM monitor before they were gone.

Absolutely, it’s gorgeous. But even panasonic will tell you it’s not for critical color correction. But it’s a killer monitor though.

What’s your playback offset set to? Just curious because you say you’re having good luck with it and both Rick and Bob say the monitor is a problem. The big difference is I’m assuming you’re running Kona and Rick is running BlackMagic.

playback offset to 4
Please remember that one example I gave did not even use an edit system, but was just from dubbing a tape onto VHS machines. A Kramer 10×1 router fed the Sony LDM-1410, and there was a DELAY in the audio, which made it appear as there was a lip sync issue (which disappeared when I put in the PVM-14L1).Bob Zelin

I’m glad were not the only ones. It is definetly the monitor, and not the Blackmagic card or the FCP playback offset (which is ussed to adjust sync with deck control not to split audio and video). I am sure because when we plug the composite output of the blackmagic into a chaep monitor it looks fine. What a bummer.

Playback offset is set to 7 frames. Seems to work for me.
