And the cost of it is?

I suspect they probably have put a few steadicam ops out of a few jobs, to be honest. Yes, there are things they don't do well, but ain't that the way for everything.

Yeah, who?


In Topic: Sony A7s2 noise in shadow

27 August 2018 - 05:33 AM

There's nothing terribly wrong with what you've shot. Silhouetting the subject against a bright window as you have in a couple of shots means you are quite dependent on shadow detail which is where the noise is most visible, but it's not the end of the world.

 

One question worth asking is what sort of grading you would expect to be done on this material. Your camera setup suggests that you're going for a low-contrast original. I'm not sure if you're doing this because you want a low-contrast result or if you expect the material to be graded. Either is fine, of course, but be aware that the internal recording on the A7S2 is quite low bitrate and does not stand grading very well. If your editor is not expecting to do any grading or finishing work, you might want to ensure you're sending the pictures in a way that won't need further grading.

 

Certainly the A7S2 is not a noisy camera at 200 or 400 ISO. It's just not a very good recording.

In Topic: 4k video - decent bitrate?

24 August 2018 - 04:50 AM

The other thing to be aware of is that when you ask an encoder for 100Mbps, it's a target. With some formats, such as H.264, the encoder will try to achieve that target by using a particular arrangement of compression settings, compress a frame (or group thereof) and see how close it got to the target. Sometimes it might try again with different settings if it was wildly off. Other codecs (such as ProRes) use fixed settings per frame, so if the frame is simple and it compresses really well, the bitrate will drop.

 

In neither case will the file usually hit the specific bitrate with any degree of precision. Some rate control algorithms are better than others.
