GH5 No audio for first seven frames of each clip?

IronFilm said:
Well they are 2x GH5, not the GH5S, so Aux TC is the only option.



For me it is not about using the first few frames or not, it is the fact that the video ends up being out of sync. At least it is a consistent offset.

No it is in sync. Just missing audio for the first 7 frames. If your external sync is taking the start point incorrectly then of course that will be out of sync but the audio in the camera is in sync.

I absolutely have adopted this practice where possible. But some shots come out of nowhere (I'm in the traffic industry and traffic is sometimes is very unpredictable) and suddenly there's no audio at the beginning of the clip. Not a HUGE deal, as the workarounds here have mentioned, but still a nuisance nonetheless.

Just playing devil's advocate here.

Let's say that this issue isn't a bug but a by-product of how the encoder works. So would you rather Panasonic delayed video recording by 1/4 of a second so that both video and audio begin together?

In that case you're missing the first 1/4 of a second of the video anyway, so choose your poison.

And advocate hat off, this isn't some Panasonic "deep-state" conspiracy to frustrate a large number of camera owners.

You missed my point about Aux TC being used, thus if the audio doesn't start at the correct time then the TC could be applied incorrectly to the GH5 files.

By-product = bug.

NOT something intentionally developed as a feature. Of course not! As it is a bug.

All your devil's advocacy is doing is saying this is a bug that Panasonic can't solve and/or they can fix it but only be trading it off for a different type of bug that they also can't solve.
 
Must be a slow news day since people have nothing better to complain about.

In all my years owning and renting cameras I have never seen a group of people nitpick and complain so much over a $2,000 camera.

I get this is annoying to some of you and when I first bought a GH1 it was annoying to me as well but I learned to quickly get over it and move on to other concerns. There is nothing we can do about it and since the encoder has been that way since the very first Panasonic DSLR I'm willing to bet there is nothing Panasonic can do about it either. Like stoneinapond said its likely a tradeoff of a delayed start or just a delayed start with the audio. Considering Panasonic has constantly pushed the envelope of DSLR encoding technology I'm pretty sure it has nothing to do with "ignorance" lbut entirely to do with there are a set of tradeoffs and they chose the path where the recording starts a bit faster but the audio isn't there yet.

Regardless of what the cause of the issue is it doesn't change the fact that it is minor and 99% of users are not affected by this in the least. I'm sorry if it bothers some users but seriously if thousands of users don't have an issue with it at all is it really a bug? A bug means a fail point for a large amount of users or a mistake. This is something that affects everybody but really nobody even really notices it so it is by design and not a bug. A bug indicates something that needs to be fixed because it affects people from using the camera effectively. That is not the case at all. It is 1/4 of a second and not much effort to just start the camera a little early.

I develop software and I can tell you no group of software developers on the planet would consider this a bug. Its a limitation of buying a consumer camera to use it for professional work. Don't want issues like this then go out and buy a EVA1. Thats why there is a professional market for cameras. Not just a way for people to waste money but a lot of this little things are addressed better like 7 frame audio delay or a HDMI output delay.

We got it, even Panasonic's farts smell good! :)

Did not misunderstand at all. My point was how are you doing aux audio. If you use a timecode slate and feed to both GH5 and aux recorder I think you will find they are in sync. Just the audio on the GH5 is missing the first 7 frames. If you are using the headphone out of the GH5 to start your aux recorder then you have even more problems because it could be realtime or delayed to sync with video and still be missing 7 frames. Page 195 in the manual. A better solution is the XLR unit for the GH5 that can record audio at 96kHz and 24bit if you want. Then you will be in sync but missing the first 7 frames !!!

So it's a bug. Sometimes you need that little bit of audio. Even if it's not a bug, it's often annoying, dump a whole lot of good clips on a timeline and you've got seven frames of silence that you have to cut from each clip, which you can do with preprocessing or a script if your NLE allows scripts, but you shouldn't have to.

Right!

The other problem with the GH5 is that is does not go to 11, you know when you are having that great recording and you want to push it just one step up to make things a bit more Hollywood-fähig.
It's just not there, another bug for sure. :p
 
Of course its a pain in the bloody ass,if all recorded clips run smooth and would not need touching at the start having to cut 7 frames off at the start is time consuming,as i said Pana bridge cameras are the same,mine anyway.
 
I don't think I have ever used any of the first few minutes of a clip recorded so not an issue for me. I think if you use the GH5 as a camera head and record to external recorder the audio should be there all the time. If you initiate recording from the GH5 and trigger the external recorder I am not sure. Will try on my VA.
 
I have just checked using my Blackmagic Video Assist. If the camera is used just as a head and the record button on the VA is used to start recording the audio is there all the time. If the VA is started using timecode from the GH5 then there is a 3 or 5 frame missing audio similar to files from the camera. I expect this is the HDMI output taking output from the recording system so will have the normal missing frames.
 
Ron Never used the first few minutes of a clip :Drogar-Shock(DBG):i would have binned some interesting wildlife over the years.Its not the loss of the first 7 seven frames that is a pain but having to remove them all time if i am using on cam sound which i do at times,if i will be using prerecorded sound there is no problem.

In that case does the loss of 7 frames of audio really matter. Do you really depend on your camera to record wild life audio ? Every application is different I concede but for me shooting in the theatre I start the cameras rolling the moment the doors are closed which in the main is several minutes before the show starts.
 
I just don't understand the angst here. I really question your edit choices if the first 7 frames (not seconds, FRAMES) of audio make a difference. Cut in late, cut our early. You should probably be doing this regardless of what the camera does with 7 frames. Let's say this again...7 FRAMES.
