a7s ii jitter issue during tracking shot with Ronin-S

Recommended Posts

I've been trouble-shooting for the last day to no avail!
There's some jitter in my footage but I can't tell if it's happening during capture or playback. 
It's a 4k ProRes clip shot at 30fps and the file is living on my internal drive. Upon playback, it starts off smooth but then starts to jitter. However when I scrub back and re-watch the section that jittered, it's not there anymore. But then it happens again somewhere else. That points to a playback issue on my computer but I have a new Macbook Pro (2019) with the AMD Radeon Pro 5500M 8 GB that should playback without a hitch? I shot the same tracking shot in HD and it seems to be doing the same thing during playback. 
Any thoughts? Kind of at a lose at this point :@ 
Thanks .

It depends on what program you’re using to view it, but it’s probably not defaulting to using that video card (unless you intentionally changed the setting). There are two video cards in a MBP, and most programs use the less powerful built-in Intel to save battery. 

if you’re running Big Sur, go to System Preferences > Battery > Power Adapter, and turn off ‘Automatic Graphics Switching’.

Output file direct from camera to TV to see if it's the same. If TV plays fine then it points to a computer playback issue.

Looks like you're using a gimbal for panning. Everything I've read is says IBIS should be turned off when on tripod or gimbal both for stills and video.

    • Hi there. I have a similar issue with my ZV1, I think? It's annoying - to the point where I'm wondering if I a have a fault with my device and am considering returning it under warrantee. I use it to film yoga instructional videos. They are sometimes 90 minutes long. I know that inorder to run for this length of time, the camera needs to be plugged into the mains. So I plug the camera into the mains and double check that the mains charge is showing - the battery icon confirms this : it has a little plug symbol beside it. So - I should be good to go. However.  The camera still turns off after an hour or so, saying the battery is flat. Interrupting the filming. Which ruins the whole video. At that point, if I go back to the camera now its battery is flat and pull out the charging cable from the mains and put it back in again, I can continue recording for 90 minutes plus as required. My issue is: the Sony ZV1 is not using the mains while the battery is charged. It continues to run on battery power. Then switches itself off (infuriatingly). And then - only at that point when I plug it in again and turn it on again does it start using the mains as it's power source. I'm 99% sure this is what is taking place but still on a learning curve are trying many workarounds this problem... not of which have been successful yet. I'd really appreciate some help with this. The next thing I'm going to check is deliberately flattening the battery before I start filming. But this seems a clumsy workaround. Otherwise - absolutely loving this camera! A huge improvement on my old camera. But only if I can RELY on it! Best wishes Frances  
    • From direct comparison on an American site and from what I can tell from reviews, it looks like the Tamron F2.8 SP Di USD will be my choice over the Sony. The optics appear to be very similar, but the Tamron's USD focussing appears to be quieter and as quick (although not as accurate in low light). So the main factors for me are: Apparently the Sony was optimised for cropped sensor, although advertised for use with full frame as well.  Weather sealing (Yes on the Tamron, no on the Sony) and the colour of the body is more discreet - and, of course, it's £100 cheaper. If the Sony SSM II was in my budget, that would be a different story. Anyway, when I've taken the plunge I'll let you know if I'm happy with the choice!
    • Just an update to this, I have updated to firmware 1.02, but I get still get the 2nd base ISO at 10000. It seems that I have the only A7Siii in the world that does this😬😬
    • I got a new Sony RX 100VII but I will keep the 100II. I have been looking into the specifications of both chargers but didn't come to a conclusion. Since teh batteries and the same, can I use the charger of the most recent camera to charge the old one ? Thank you !  
    • I have this problem as well. Glad to see I'm not the only one but it appears like this is a common issue. Sorry to respond 4 years later but I'm hoping to resurrect this now to see if there's been a solution since 4 years ago!
