Re: Sony NEX-FS700 - It's real
Shallow focus in slow motion... It will be like, wait for it, wait for it, sharp focus, ah nuts soft again.
As an aside, there is still a supposedly significant firmware upgrade for the fs100 coming at the end of NAB. Many of the software based features, touch to focus, cinegamma, etc, could still be coming to the fs100, to allow it to be a competent b-cam for the 700. |

But I don't think the FS-700 will be sold in numbers that can compare with number of video-DSLR's and large sensor camcorders. So slowmotion at real high speeds won't be as common as shallow depht of field. I'd go for slow motion with shallow DoF on a Cinevate Atlas track :-p |

I fear this will only make it worse. But maybe as more and more "cool" techniques become available, they will all somehow filter back into appropriate proportions. |

Like a lot of things, it has to be appropriate. otherwise it just becomes an affectation. |

But you are most welcome to elaborate on how they achieve the slow mo and why it affects quality. Quote:
(BTW, it will be a project to try and test the slow mo of the FS700.) |
Re: Sony NEX-FS700 - It's real
Adam Wilt has been running tests on the slow motion, I imagine he'll put them on line at some stage. He was testing a pre-production camera and found it slightly less sharp than at normal frame rate, although it could be an issue with the camera's status.
There seems to be some line skipping at the higher frame rates seemingly the missing lines are interpolated back, but they look "better than they should". I'm sure the slow motion will work extremely well for most people's requirements. |
Re: Sony NEX-FS700 - It's real
Ooops! Thatīs a real disappointment and might be a deal breaker for me.
I assumed the 240 fps are maximum quality. So itīs just another mode to play with but nothing to use seriously... |
Re: Sony NEX-FS700 - It's real
In a new record for feature disappointment, high res high speed above 60fps and under 10 grand is out before the camera is even on sale because its not true 1080 at 480fps.
If someone were serious about high speed I'd think they were already in the market for much more expensive specialty gear anyway and not expecting anything from a lowly video camera. |
Re: Sony NEX-FS700 - It's real
In practise, at the 240 fps I suspect you wouldn't notice the difference in quality. I gather the drop off was very slight on his initial test, so unless you're filming test charts the slow motion is the key feature. It's at 480 fps they use the the line skipping.

Re: Sony NEX-FS700 - It's real
Here the Adam Wilt slow motion test I mentioned, together with some thoughts:
http://provideocoalition.com/index.p..._amuse-bouche/ I gather the camera was quite power hungry, perhaps it's because of the processing of the slow motion material. |
Re: Sony NEX-FS700 - It's real
Adam Wilt's article referenced above explains the business about how it copes with all the data in slomo. Apparently the camera uses line skipping (a la DSLR) to achieve the high frame rate.

Re: Sony NEX-FS700 - It's real
The very high (480, 960) .
There is no line skipping in the 120 and 240 FPS mode. |

It's like a lot of highspeedcameras: there is a maximum bandwidth of data. More fps can only be achieved by dropping resolution. Is there any 120fps and 240fps imagequalitytest comparing it to 30fps or 24fps? I'm also curious about noise at higher iso/dB, since that will tell us more about low-light performance and the abilty to get a deeper DoF when needed. (Sony: send me a cam to test it :-p) |
