I wanted to share a test video I shot with my new GH4 out at night on the streets of NYC.    It was shot on the 60fps VFR mode with a Sigma 30mm 1.4 for Nikon + Metabones speed booster.    I've heard

Hey guys, Wanted to share a new GH4 test I shot with the SLR Magic Anamorphot + Sigma 30mm. The grade was extremely minimal and the colors you see are mostly coming from my custom CineV settings. Hop

Isn't the whole argument against Blackmagic that it takes a good colourist to make the footage look good? I think it's horses for courses really. Blackmagic cameras aren't really suited for run and

I read with great interest your article "Discovery: 4K 8bit 4:2:0 on the Panasonic GH4 converts to 1080p 10bit 4:4:4", but I am new to the technical details there. I have a GH4 that I am trying to use for serious filmmaking and would like to know more about this topic. Especially this question and answer near the end of the above article:

 

"Will it require specialised software to do the transcoding and downsampling?  or can existing methods be used?

 

As long as you upconvert to RGB and 10/16-bit first, you get the benefits. A 16-bit comp can demonstrate this to be all true."

 

Just what steps should I take in, say AE CS6, to accomplish this upconversion and 16-bit comp?

Or, what other things do I need to do to get 10-bit 4:4:4?

I'm a real newbie and don't know my way around the block yet.

 

So far, I have simply been dropping my 4K footage on a 1080p timeline in Premiere CS6 and getting nice results, but would like more latitude for grading, etc.

 

Thanks much

Joe

What are peoples opinion on GH3 vs GH4. I feel GH4 possibly looks more like video when compared to GH3. I feel the extra sharpness of the GH4 is really something that imo doesn't look right. I would have much preferred they would have simply worked on improved iso and dynamic range.

Can anyway please help me with some nice neutral settings? Everything I've tried on the GH4 looks too sharp or just lifeless + too much yellow in skin tones and then too much magenta. I'm finding it almost impossible to get the actual color I want out of the GH4


Are you using Cine D and 180°? Are you grading?

Has any consensus been reached on using the BMCC (not the BMPCC) Speed Booster (Nikon mount in my case) with the GH4?  

 

Does anyone here use that combo?

 

Can it really damage the camera?

Hi,

 

I just received a GH4 and something bugs me with the EVF:

When I set video setting to 4K, the refresh rate of the EVF drops to maybe 15 fps, and that is a problem for panning with fast moving subjects.

It seems I get this behaviour even in relatively bright conditions. I tried to set the EVF rate to 60 fps in the custom menu, with no result.

What suprises me is that with the same setting, the rear screen view remains fluid, so I cannot understand why the EVF nedds a slow refresh rate.

 

Is that a normal behaviour ? Didi I miss something in the settings ?

 

Any help greatly appreciated ;o)

What's your shutter speed?

After doing a little more research, I have discovered that the issue that you see is not because of C4K or UHD, but it is becasue the unit at 24p. No matter if you are in C4K/UHD or 1080p the refresh rate is lower at 24p as opposed to 30 and 60hz. I must admit I have not spent much time with my camera out of 24p creative movie mode  :), so I really never paid much attention to the refresh rate of the monitor/EVF as it was fine.

My unit behaves as follows.
24Hz: slow EVF and monitor in all mov. settings
50Hz: slow EVF and monitor only in 4 K settings
59.94Hz: slow EVF and monitor in 4K settings. The 24fps 4K setting seems the worst.
For all settings EVF seems wors than monitor.
It never bothered me too much and I hope this post won't change that ;)

      Well, it’s been 8 months since I completed this and almost a year since I promised @mercer to post it once completed

      I don’t really know what to say about this, it’s my first short and I wanted to try this medium after trying music, photography, drawing/painting and all sorts of writing in order to figure out myself and my depression.

      It took me months to complete due to my mental state and lack of energy and I intended to post this sooner, but life can be a little too much sometimes. Or very often in my case.

      Even though it was the hardest creative thing I’ve done in my life, (despite having a background or experience in most of the separate artforms that make up a film) I was really lost in the entire process and I developed love/hate relationship to it. I wanted to quit all the time when I wrote it, when prepping, when shooting and during the long, motivational drainage that is editing.

      But I guess that’s also where the love was born. No matter all the mistakes I made, I could somehow save it and make a decent first short thanks to the editing by re-arranging the pieces I had. Throw away most of it, stretching what was left of it, slowing or speeding up some of it, playing some of it in reverse. Dubbing in new sound (needed, cause most of it was unusable. Note to self: Don’t forget sound!

      I’ve tried to make another short since, but haven’t completed the shoot. I don’t know if I’ll finish that one, it’s just a silly comedy I made with my then girlfriend, now fiancée on my phone (This one was shot on the DVX200 before anyone asks, cameras are important on this forum apperantly, hehe) because she wanted me to make something less depressing, but I guess I’m just a gloomy guy, all my new ideas are based on my different malfunctions.

      Hopefully I’ll work up enough energy to make another, I really want to.

      Anyway, enough talking. I hope you’ll give this a go and give me some pointers, but go easy on me, okay?

      Now, pick you poison:
