PTA Posted November 5, 2013 Report Share Posted November 5, 2013 Will the F55 accept and display ext. lock to a TC source without genlock, say from an ERX? Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted November 5, 2013 Report Share Posted November 5, 2013 It will just pick up the count as a jam sync, fine. It's only "locked" to its internal clock in this mode. BTW so far it will only "see" ext TC in 23.98, not in 29.97. philp Quote Link to comment Share on other sites More sharing options...
postaudio Posted November 5, 2013 Report Share Posted November 5, 2013 I believed we shot at 29.97 and I had one on on Lockit box and one jammed once start of day and one after lunch and it was in synced. Quote Link to comment Share on other sites More sharing options...
Andy P Posted November 5, 2013 Report Share Posted November 5, 2013 I've been using an ERX on an F55 for a few long projects over the last months. No problems at all. Solid sync from the ERX, receiving Zaxnet TC and guide audio from a Nomad. These were 25fps projects. You can set the F55 to display EXT-LK in the viewfinder, if your camera op is ok with that. Unfortunately there is no option to have it displayed on the side LCD at the moment. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted November 5, 2013 Report Share Posted November 5, 2013 If you got 29.97 to work with the F55 then you have cams with diff firmware than we have around here. So far none of 5 or 6 F55s would accept external sync or TC @ 29.97. philp Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted November 5, 2013 Report Share Posted November 5, 2013 If memory serves, a 2 camera F55 shoot I did a few months back used 29.97 drop frame. I recall that once we figured the settings out they both jammed fine to the Denecke SB2a I had on each. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted November 6, 2013 Report Share Posted November 6, 2013 29.97 DF would not fly with our workflows, but we couldn't get the cams to see it anyhow. The only way we got it to take 29.97 was to jam @ 23.98 then switch the cam to 29.97. Not ext sync either. philp Quote Link to comment Share on other sites More sharing options...
Marc Wielage Posted November 7, 2013 Report Share Posted November 7, 2013 Page 57 of the manual talks about an Internal/External Sync selector button, and there is a Genlock BNC input for sync on the camera. "In theory," it should work. Here's what the manual says: No 29.97 DF that I can see. If it doesn't work, it wouldn't be the first time a Sony product had some kind of weird software problem that didn't quite work. I'm told the F5 and the F55 have gone through some major debugging over the last six months, and I don't know what the current firmware is.

Jim Gilchrist Posted November 7, 2013 Report Share Posted November 7, 2013 I fed timecode to an F55 yesterday. From my 664. The F55 does 29.97 DF as well. A job I was on has one come out of the box from a rental house set up for it. Best regard, Jim Quote Link to comment Share on other sites More sharing options...
Marc Wielage Posted November 8, 2013 Report Share Posted November 8, 2013 Hey, I've had the manuals be flat-out wrong before, so crap happens. I once tried to access a software feature that just plain wasn't there, and they told me, "oh, we haven't released the final version of the software. You're still using the Beta!"

David Lipka Posted November 11, 2013 Report Share Posted November 11, 2013 I used to feed an F55 with TC and Genlock. When i disconnected TC it was still written EXT-LK on the screen.. but after few tests, it was not so accurate. Even with genlock we always had 0 to 2 frames of offset. I often had theses values with Sony cameras Quote Link to comment Share on other sites More sharing options...
Patrick Tresch Posted November 11, 2013 Report Share Posted November 11, 2013 Hello David! I fear it's due to signal processing. So not only Sony, but Canon, Red,... also have this issue. I think so. One question. What is the difference betwen GENLOCK, Synch, and trisynch level? Pat Quote Link to comment Share on other sites More sharing options...
pkautzsch Posted November 11, 2013 Report Share Posted November 11, 2013 Even with genlock we always had 0 to 2 frames of offset. I often had theses values with Sony cameras On a doco shoot I was helping out last year, they fed Lockit TC to an audio track. Cam was EX-3. They had some kind of "translation" plugin in FCP.

studiomprd Posted November 11, 2013 Report Share Posted November 11, 2013 " One question. What is the difference betwen GENLOCK, Synch, and trisynch level? " well, OK, this is going back to square #1... GENLOCK is video "sync", sync is a synchronizing signal (hey, it could be GENLOCK), and "trisync level" is an incorrect term. " Even with genlock we always had 0 to 2 frames of offset. " offset is easy. Quote Link to comment Share on other sites More sharing options...
PTA Posted November 13, 2013 Author Report Share Posted November 13, 2013 I used to feed an F55 with TC and Genlock.

I often had theses values with Sony cameras So on a semi-related note, I'm currently using some Sony F3 cameras and what I'm seeing now is the external lock logo seems to always be on screen no matter if timecode is connected or not. The camera seems to take the time code, but the external lock seems to be there regardless. Not sure if that is a software thing or not, but there also doesn't seem to be any option in the viewfinder menu to enable or disable external lock logo. I'm guessing it is some older firmware. Anyone else experience this? Quote Link to comment Share on other sites More sharing options...
