Re: Report on the Yi 4K+

This is an odd post in a thread labeled and devoted to the 4K+. The 4K+ has a processor that is twice as powerful as the one in the camera you are posting about. That is relevant not only to the...

Re: Report on the Yi 4K+

I hate AGC, squashing dynamics and pushing up noise when there are low level sounds. However, in recent years almost all cameras use a limiter rather than aggressive AGC, and it is much better.

Re: Report on the Yi 4K+

Here is low-light 4K test footage - shot at 4K24P ISO 800. It was very dark - one light bulb in the ceiling. This was shot to imitate what the scene looked like, not to push to make it brighter than...

Re: 3 new Sony 4K palm camcorders

I guess you do not keep up with the action cam market. The Yi 4K+ does 4K60P, and it is $339 and has been out for months, and it is the same size as the GoPros. And it does not overheat (the GoPros...

Re: Sony A6500 Color

The "After the Rain' video was shot with the 50mm f1.8 OSS. It is perfectly fine. The real issue is focal length - shooting 4K at 30P, the 50mm is like an 87mm lens, telephoto. The 28mm is like a...

Re: Incredible Major Bug (fixable) in Vegas 15

I was notified today by Magix that this bug "will be remedied in a future update to the Vegas Pro 15 software." No date given, and they recommend using Vegas Pro 14 in the meantime (because I have...

Re: Sony A6500 Color

I like the Sony FE 28mm f2.0 lens; compact, good for low light and a generally useful focal length. Very sharp. The A6500 IBIS effectively stabilizes the lens for handheld use. And a bonus is that...

Re: Sony A6500 Color

For top quality 4K, you have to shoot in APS-C mode on the A7r ii, so you don't get that full-frame look. I have not as high as ISO6400 on the A6500, but at 4000 or so it looked good.

This was...

Re: Sony A6500 Color

Thanks. I guess I have to say the A6500, for two reasons: 1. The AF is much better. Does not mean I use AF a lot, but AF works to achieve focus that I can then lock. And when subjects are moving...

Seems much improved over previous models, including the A7r ii and A7sii.

Re: Report on the Yi 4K+

No alteration in post, except some gamma adjustments.

There is a spot meter mode, which will be very useful for spotlit scenes!

Re: Report on the Yi 4K+

The wide-angle lens ensures a big DOF. See the close-ups of the telescope, with the distant vista still in focus.

No stage stuff yet - the camera does need a lot of light.

Re: Report on the Yi 4K+

This is the Yi 4K+. It supports an external mic through the usb-c port (same as the GoPro 5). Yi sells a cheap adaptor - analog port to usb-c.

One must use an external mic when the camera is...

Re: Incredible Major Bug (fixable) in Vegas 15

No, my files were standard avc 420 with aac audio. Many others have encountered the problem with avc 420 from, for example, Sony cameras.
