In most instances, I would highly advise against using 96fps on the GH4 as it just doesn’t deliver great results. In the end, this translates to much poorer final image quality than you might hope for. To put things in perspective, when you’re shooting at 100mbps at 24p you are essentially spreading out that 10mbps of data over only 24 frames, whereas when you’re shooting at 96fps you are getting the exact same amount of data per second, but now you are spreading it out over 4 times the amount of frames, which means each frame gets 4 times less information in it. This may sound like a lot, especially since you may be accustomed to shooting with DSLRs that have very low bitrates (17mbps, for instance), but when you get up into the higher frame rates this really isn’t enough. When shooting on any of the frame rate settings in VFR mode, you are limited to a bitrate of 100mbps. The caveat however is that the data rate is on the lower side. If you’re using this option, the GH4 will actually adjust the clip internally so that your file plays back in 24p (in slow-motion) as soon as you’re done recording, much like a RED camera or other higher end cinema cameras would. It’s tempting to use the VFR mode on the GH4 all the time as there is so much flexibility with regards to what frame rate you can use, and it also saves time in post since you don’t need to slow down your footage. The other option is to use the variable frame rate setting in the menu to shoot at anywhere from 2fps all the way up to 96fps. The first is the old fashioned way (as you would have done with a GH3 or any camera that shoots 60p), which is to shoot at a true 60p setting and slow down your 60p video file to 40% (24p) in post. If you want to overcrank on the GH4, there are two main ways that you can do it. This is pretty astounding, and certainly makes the GH4 an incredibly powerful to own – but unfortunately not all frame rates are going to work as well as others. No other DSLR/DSLM has the ability to over crank the way the GH4 can, which offers variable frame rates at up to 96 frames per second. I run a GeForce GTX 1060 and an intel i5 7600K with 16GB of RAM, so my computer specs are fine, but i still don't know what's causing this problem in the game.One of the biggest reasons that filmmakers are falling in love with the GH4 is because of it’s amazing ability to shoot at high frame rates internally. but other times, i'll still have vsync on and all the same settings and it'll stutter a lot and vary between 45-55fps, making the game more difficult to play. The weird thing is, sometimes when i load up the game and play, i'll keep my vsync on and it'll stay at a constant 60fps no matter the settings. i also attempted messing around in the NVIDIA Control Panel, but no luck still. i have tried rolling back the driver to a previous version but that hasn't worked either. before i installed the driver i was able to run max settings at 120fps with little/no problems. I've been having problems with the framerate in this game and haven't been able to fix it, even though i've spent hours trying.Įver since i installed NVIDIA's last GeForce Game Ready driver, the framerate has been constantly stuttering even with vsync turned on and settings on low.
