So, Synchro Scan works for your monitor while filming, and Flkr Decrease is for actual flicker compensation in your recordings? Sorry, just trying to clarify my understanding. Thanks.
Not exactly. Synchroscan compensates for a frequency mismatch between a light source (overhead lighting, CRT televisions, LCD displays… any number of things) and your recording frequency - and is exclusively for video shooting. Flicker decrease is about shooting stills, and avoiding the same kind of flicker, but typically in overhead lighting in places like a sports arenas where rapid fire sequences could result in some being dimmer than others.
Again thank you for answering my question. I have been looking into Synchro Scan, because I got flickering when shooting at 60p @ 180° under fluorescent lighting. BTW I'm recording in PAL. And although I'm not good at calculating the right shutter angle, I luckily found this handy calculation tool from Red www.red.com/tools/flicker-free-video (it would be cool if Panasonic would offer such a tool (in camera) ) And @ 216° there is indeed no flickering anymore. :-) But when I put 180 fps into the tool it's says that there isn't a safe shutter angle. Is this because above 100 ftp the safe shutter angle is beyond 360°? So in other words it isn't possible to shoot at 180 ftp under fluorescent lighting that runs at 50hz? Or has the Gh5 another trick under its sleeve? BTW if this will be in your GH5 course just tell me, because I'm thinking of signing up. As I got too many such questions about the GH5. And I'm not that good at reading the manual. P.S. Sorry again for my dyslexic question. But you got it the last time so I guess you get it this time too.
Hey Floris. Hm, that's a really good point (and no I wouldn't include this in my training… it's a bit too inside-baseball!). Also you said you're recording in PAL but at 60p, which doesn't match. PAL would be 25Hz which means 50p. Also very cool tool… and quite interesting; if you put in 29.97 it says to use 87, 174, 261° but if you put in 30fps it says to use ANY! I don't understand the math here but as to why it says not to do 180fps, yeah I'd guess it's because the shutter angle would have to be beyond 360. Interesting. Thanks for sharing!
I just meant that the Rec Quality was set to 4K/8bit/100M/25p with the Variable Frame Rate set to 60p when I did the test. Obviously when testing VFR at 180 fps the camera was set to FHD at 25p. I hope it makes sense now. It wouldn't be first time for me to ask an inside baseball question ;-) (Although it's the first time I seen that metaphors) Well your training course is properly a good idea to fully learn all the functionality of the camera. And I will feel less hesitant to ask you these inside baseball questions ;-)
Floris It's that the shutter speeds would be to high to avoid flicker at 180fps. There is a certain shutter speed max (I think 1/100 for 50hz) any faster than that and it's to fast and the camera will see the flicker. You just gotta live with the flicker at high framerates as far as I know. Some shutter speeds will be better than others above the limit but still flicker.
Hey Joseph, I have never been able to figure out exactly how to make adjustments in synchro scan to match screens, lights, etc. Is there a formula? I swear I cannot find anyone online explaining this. If I have my camera set to 180 degrees and have it on synchro scan it allows me to make micro adjustments. That I understand. What I don't understand is what the relative shutter degree is relative to the hz environment I might be shooting in. This shows up a LOT when trying to do VFR modes.
I actually just did another video related to this topic ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kbBhaE7HWYY.html - there’s a calculator I’ve linked to there that will help calculating angle for 50/60hz lights. But if you’re trying to match a screen or display, as far as i know it’s just trial and error. Keep running through the range until you find it. You’ll see the waves/rolling slow down as you get closer.
Is Synchro Scan available on the Lumix S5? I can't seem to find it, maybe because it isn't there in the first place? My previous GH5 had this function.
Here's a quick question I hope you can help with. When I take a photo in RAW mode the playback of the images seems to be a crop of the actual photo from what I was viewing on the screen. Driving me nuts. Even read the manual but can't see anything mentioning this. When in jpeg photo mode it doesn't do it. Hope you can help. Carl
Hi Joseph. Need your help. I’ve uploaded a LUT to my SD card but for some reason the “read lut file” is not highlighted. Kindly assist? It is a .vlt file and is not loaded in a folder on card.
Hello Joseph! I've been having a lot of problems with flickering of lights when filming indoors, under artificial lighting. I know I can fine tune my shutter angle to line up the camera with the frequency of the lights, but somehow my gh5s and my ninja V auto corrects the flickering on the screen. Even though it's still there. How do I sync my gh5(s) with the right frequency of artificial lighting, using shutter angle & sync scan? Or is there another way? Thank!
ah, it's a fine adjustment of the electronic shutter on video cameras (electronic shutter control) usually expressed in HZ (hertz) Basically you can either adjust the shutter angle which usually is set at 180 degrees at 24P or 25P and ESC setting of 60HZ. Usually you can dial the ESC to 2 decimal places so it's very precise. Usually it isn't necessary because you can adjust the shutter angle to 1 decimal place in degrees.
ESC is the electronic shutter control. Most video cameras have ESC and shutter angle fine adjustment. The shutter angle is expressed in degrees start at 180 degrees at 24 frames per second and the ESC is expressed in HZ hertz or 60 HZ
+kevin n Oh thanks. So on the Gh5 if you're in shutter speed mode you can fine tune the shutter speed. If you're in angle mode, it switches to angle by degrees. The GH5 will express it however you like.
Thanks! It's strange how these terms all basically refer to the same thing but come from different technologies i.e. film still cameras, film movie cameras and video cameras.
Yes. Still not as good as a bigger sensor camera but depending on your needs and expectations, many report "usable" up to 6400 ISO. Again that depends on what that means to you!
