postaudio Posted February 26, 2013 Report Share Posted February 26, 2013 Hi I was wondering if anyone has this issue. I was shooting with 3 cannon C300. Jammed sync TOD in the morning and after lunch. We also slated. Frame rate is 23.98 I heard back from post that audio and camera not in sync even using the clap/ slate. Time code drifts about 10 frames. Do I have to set my time code to a different rate? I'm recording 24bit 48K and set my 664 to 23.98. The last time I shot with the same camera I was using a 744T and everything was in sync. I was wondering if I need to change my frame rate or if the camera needs to be updated to new firmware. Any idea? Thanks. Ben Quote Link to comment Share on other sites More sharing options...
Glen Trew Posted February 26, 2013 Report Share Posted February 26, 2013 When one of these takes is synced with a clap slate, how long does it take to drift 10 frames? This info could help determine where the problem is. Glen Trew Quote Link to comment Share on other sites More sharing options...
pverrando Posted February 26, 2013 Report Share Posted February 26, 2013 The C300 timecode will certainly drift with battery changes, power ups/downs, menu changes, etc. It's even documented in the manual. Quote Link to comment Share on other sites More sharing options...
bmfsnd Posted February 26, 2013 Report Share Posted February 26, 2013 It's also worth making sure that their NLE's audio settings are set to 48/24. Quote Link to comment Share on other sites More sharing options...

ShubiSnax Posted February 26, 2013 Report Share Posted February 26, 2013 I've noticed on the C300's, where the BNC cable pin inserts into the camera, there isn't solid contact. I was losing sync with 3 C300's on a shoot. Simply jiggling the cable would sync the camera back up. I had the tech tighten up those BNC holes and all is well.

Rob Lewis Posted February 27, 2013 Report Share Posted February 27, 2013 Other way around. C300 loosing sync with 664. Quote Link to comment Share on other sites More sharing options...
Richard Ragon Posted February 27, 2013 Report Share Posted February 27, 2013 You didn't use Sync Boxes? Why not? All cameras don't have a good timing mechanisms.. -Richard Quote Link to comment Share on other sites More sharing options...
snd.waves Posted February 27, 2013 Report Share Posted February 27, 2013 +1 shubisnax - I found this on one C300 that I shot with. Quote Link to comment Share on other sites More sharing options...
Richard Walters Posted February 27, 2013 Report Share Posted February 27, 2013 I'm currently shooting with (3) C300's and noticed that when a battery is changed out on any of the cameras, the frame rate jumps ahead between 2 and 3 seconds. I also had a camera drift ahead when media was changed and formatted. Unfortunately I don't have (3) lockits in my kit so the second AC simply lets me know when a battery is changing out, or media is dumped and we rejam right away. Fortunately all the cameras are locked off in a studio, so this solution works well for us. In the future I'd certainly have lockits on ALL cameras.

postaudio Posted February 27, 2013 Author Report Share Posted February 27, 2013 Would love to have lockit boxes for all cameras if they have the budget for it. It's already a battle to make client pay for extra comteks. Quote Link to comment Share on other sites More sharing options...
john Quinn Posted February 27, 2013 Report Share Posted February 27, 2013 The rule is if it has got timecode in it ,stick a lockit on it. If production do not want to pay for them then explain as nicely as possible that they are making a mistake and that it will save them money in the long term.If you do not do this then when things are out of sync they will always blame the sound dept as timecode is considered our responsibility.But if you have explained to production that cameras in multi camera or a separate sound scenario will not stay in sync with each other and they choose not to heed your advice and spend a few pounds upfront then you have done your job and you are in the clear.

studiomprd Posted February 27, 2013 Report Share Posted February 27, 2013 " if you have explained to production that cameras in multi camera or a separate sound scenario will not stay in sync with each other and they choose not to heed your advice... " then when you hear from post, you can explain that they need to complain to the producers who you spoke to. Quote Link to comment Share on other sites More sharing options...
john Quinn Posted February 28, 2013 Report Share Posted February 28, 2013 It is terrible Mike that we live in such a buck passing world ,but you do not want to be left carrying the can when the shit hits the fan just because someone holding the purse strings does not know they're arse from they're elbow .

Tyler Faison Posted March 1, 2013 Report Share Posted March 1, 2013 One thing to look for is to make sure you're not on 24hr time on the 664. You should be on Free Run. Not sure what you meant specifically by TOD. Quote Link to comment Share on other sites More sharing options...
Marc Wielage Posted March 2, 2013 Report Share Posted March 2, 2013 "Robert Johnson is right! We'll wire the Governor!" Howard Johnson is right about Robert Johnson being right! I agree with John and Richard above: slap an SB-T or Lockit box on each camera, or they're going to drift. Quote Link to comment Share on other sites More sharing options...
Boomboom Posted March 2, 2013 Report Share Posted March 2, 2013 ''Cannon C300 losing sync...'' Oh ? It has sync ? Tyler: (TOD = Time Of Day, or free run) Quote Link to comment Share on other sites More sharing options...
Rob Lewis Posted March 3, 2013 Report Share Posted March 3, 2013 3 camera shoot today 2 PDW700's and a C300 all with Timecode Buddies rolling record run. No Timecode issues. Use sync boxes no matter what the shooter bitches about. Quote Link to comment Share on other sites More sharing options...
Boomboom Posted March 3, 2013 Report Share Posted March 3, 2013 Rob: hence my previous comment ; I've had that kind of argument with a cam assistant in the past. After 2 days of shooting post called and he had to get over his ego and slap that TC box on the cam. Quote Link to comment Share on other sites More sharing options...
BAB414 Posted March 3, 2013 Report Share Posted March 3, 2013 One thing to look for is to make sure you're not on 24hr time on the 664. You should be on Free Run. Not sure what you meant specifically by TOD. Why? What is the purpose of 24hr time mode? Quote Link to comment Share on other sites More sharing options...
Jim Gilchrist Posted March 3, 2013 Report Share Posted March 3, 2013 24 hour run on the 664 (and the 7XX series recorders) has a purpose. It sets the timecode generator from the device's system clock at power-up if the generator is no longer running on the generator's backup power scheme. Other than that, it is identical to the Free Run setting. So if you want to add a step to getting up and running - setting timecode manually - go right ahead. How 24 Hour Run mode works is covered in the various recorder manuals and can be a real timesaver. Best regards, Jim Quote Link to comment Share on other sites More sharing options...
BAB414 Posted March 3, 2013 Report Share Posted March 3, 2013 Thanks, that's how I've been using it. I don't see any reason not to use it as opposed to freerun unless you want to set TC to something other than TOD. Quote Link to comment Share on other sites More sharing options...
