Thank you! This is the *best* slow motion review of the GH4 I've found. I kept telling my peers that 96VFR looked bad and it's probably because it's chopping a 100mb bitrate up into 1/4ths but no one seemed to notice the difference despite it driving my eyes crazy.
I can't afford a better camera so i still use my GH4 for all purposes with the native 14-42 3.5 and a sigma 30mm 1.4. I hope i can upgrade soon. Brazil is terrible for filmmakers when we talkin' about pricing. Today I started filming sports and 60fps still isn't enough slow for me, so i guess i'll use 96fps and do a little post production. Thanks for explaining, still useful 7 years later!
Definitely! A lot of the bits I'll be planning on filming will have some action in them (running), so it's good to know that going all the way to 96fps might not be the best. Time to test
@@biscuitsalive was it 800 base iso for gh4, because 1600 I see much noise? And should I change any settings in that mode? What means nail exposing camera?
What a fantastic breakdown of each of the slow motion settings and capabilities. I'm looking in to picking up a used gh4 to play around with, i'll definitely have to restrict the 96fps for extremely well lit, low contrast shots... if at all! Out of curiosity, what iso was this shot at? the grain in the background of the 400% blow ups seemed excessive.
Louis du Mont 60 doesn't go well into 25. It goes nicely into 24 (40%) You can do it. (60-25) but frame skipping can happen occasionally. When my gh5 arrives (tomorrow) I prob will be shooting in 60p 4K and then I may switch to 24p for my fun TH-cam work. :)
Louis du Mont bare in mind if you have lights in a scene then 60p will more likely have strobing too. (Will have to slow shutter down to an odd degree to avoid some strobing) But not a consideration shooting out in daylight.
Thanks, I've yet to try any slow motion with the GH4. In my mind, I placed the VFR feature into the soft, artifacting video camp. Good to know it retains quality up to a point. I'm tempted by the GH5. 4K, 60p would be awesome.
Louis du Mont (you have to stretch footage to 41.6666 or something like that. So it's a bit nasty. You could export all frames as a numbered sequence and bring them back in at the new frame rate. That should ensure no issues. But it's a bit of a faff.
Louis du Mont I was putting it off. But couple of features that I really want to try out. I don't think the quality jump is very much at all for regular 4kshots. (Over gh4) But I really do like the idea of full sensor (using the whole FF lens) 4K slomo. Should make filming surfing so much better. Also the sensor crop as an option gives my 200mm a bit more reach if I need it. (Prob better option than using my 2x extender)
You are awesome. Have gh4 and had a project to do, but I wasn't absolutely sure, should I do 24fps and super slow(96 fps) or 25 fps and 62 fps (40% real speed) and retaining better detail! Thank you !
You used PAL for your tests and the 62 FPS VFR was the best setting, that's fine. But for NTSC wouldn't that mean that 62 FPS would turn into 75 FPS but with the same good quality ? So what I'm asking is this: 75 FPS/NTSC isn't equivalent in quality with 62 FPS/PAL ?
Critical Point no I don’t believe so. It’s down to the bitrate. Line binning etc that camera does at a particular speed. Best result for ntsc would likely be 60 FPS played back half speed at 30. You will get the same quality as our 62 FPS played back at 25. But we would have 40% slow mo. And you would have 50% slow mo
So for 10% more slow motion capability your going to lower your bit rate using VFR to overcrack your FPS internally slowing down your footage. I thought it would make more sense to shoot double your FPS & bit rate and have the ability to play in realtime or slow it down or color graded it more heavily. You could by pass the 50% rule and go to 25% slow down using optical flow to blend frames. Let me know what you think.
Great video, well explained. Why don't you just shoot in 60p though, if all you're doing is using available frames as opposed to frame-rate? All good though.
Hey, I'm in UK and we use PAL. so i have to switch frequency just to have the option of 60p. which is a pain if I'm filming normal scenes then flipping to slow mo. (it would screw up my shots if i accidentally filmed in 30p and also strobe with our lighting) So 50p is the option i have. and thats only half slow mo. where as 62 fps is more than 40% slow mo, so really does have more of a slow mo feel.
Anthony Jarvis no probs. Maybe check out my latest surf vid. Got some great slow mo surfing on there. (Still editing final but there’s a rough cut there in my uploads)

Wow! Best video I have seen on slo mo for GH4 yet. Thank you very much!
Anna Ferguson glad it was useful.
I also do a side by side between gh5 and gh4 slomo if you want to check that out.
Watching in 2020 and this is still so useful. Excellent comparison video Sir.
Good to hear. :)
GH4 is still a beast!
still use mine and bought 3 cameras since. :) (i love it as a b cam or handy on a gimbal cam etc.)

GARBAGEPLAY glad it was useful.
Yes 96 looks really grainy and has terrible moire.
What lens are you using? Using a sharp lens can make the footage less soft and more usable. Also infinity focus helps to sharpen things up.
Hazelbozikowski it was in focus. And using 42.5 nocticron which is pin sharp
GH4 owner - thanks a lot for this vid. Great job!

Merci de la France. Thanks
Thanks 🙏It is really helpful in deciding the frame rate.
Thanks for the review. I think I'll go out and film some slow mo today :)
Glad it was useful. :)

Great advice, buddy :) Thanks :)
James Bradbury-Willis glad it was useful.
Can you give me advice for best camera settings preset for less noise and better color grade?
Base iso. Maybe “natural” profile and nail exposure in camera.
That would have least noose I think.
@@biscuitsalive was it 800 base iso for gh4, because 1600 I see much noise? And should I change any settings in that mode? What means nail exposing camera?
@@siddharthapictures4277 200 is base for most profiles. 400 for vlog
@@biscuitsalive so I go 400, with natural profile? ( Not having v-log) have cine d and v tho. Have you done tests like in this video for my questions?

Hi! Cool video! Is it possible to improve the situation with the use of an external recorder?
Thanks! Have you played around with shooting in NTSC 60fps 200mbps to then conform to 25p?

i have GH3 and GH4.. this 2 still great..
Switch to NTSC and use 60p All-i and then slow it down to 40%. That looks even better.
the NTSC picture is smaller than PAL AFAIK, so indeed the 100mbps codec will be focused on a lower number of pixels, makes sense, thanks!

Nice comparison man :) thanks!
use sharpen in any NLE for the slo mo over 62
thanks i wish you all the best

I see, so at least the GH4 is a good 1080p/60 FPS camera.
Critical Point yep for 1080 the 60/62 FPS on gh4 is quite nice indeed.
Not as nice as the gh5 60 4K of course. :)
But great for a cheaper camera.

Hi! I have no 1080 50p in my GH4 option. How did you get it?
You are probably in NTSC mode.
50p is for PAL regions.
(Swap regions if you need to)
Great video, well explained. Why don't you just shoot in 60p though, if all you're doing is using available frames as opposed to frame-rate? All good though.

What setting should I choose to film players at a basketball game ? I want it to look like this th-cam.com/video/LZSlFyyCkhk/w-d-xo.html
Hi, do you by any chance still have the gh4 lens? I broke mine and I can’t afford a new lens at the moment
10:14 look pretty much like Inception´s opening!!!!!!!!!!!!!!!!!!!
