Post Chronos 2.1 clips here!

[marcus]

Hey I'm awaiting my Chronos 2.1 and I've already seen a few posts showing clips using the camera!

I think it would be cool to make this the place to post clips so we have a main thread instead of them being scattered around.

Here are some from other users I saw to start the ball rolling:
Photopage: (Flying Moth 1,000fps 1080p) https://youtu.be/ytQchDACNkE
Preftech: (Water tap 1,000fps 1080p) https://www.youtube.com/watch?v=T0FSl5ORMEM

Look forward to seeing more!

Here is some tests that I made today https://youtu.be/uJkoIlmD5V0

Seems that I missed the focus on last one slightly. The larger sensor and a fast lens that is sharp even wide open make focusing bit more demanding but I think I am going to get used to really making sure that it's spot on. But other than that I think the picture looks really good already. The first shot was really demanding since it was really dark and we were still shooting 1000fps.

Thanks for the Post!I think this is the fist time that i have ever seen an inofficial unlistet Video of a big channel with this little views
Focus is a bit to close towards the Camera on the Second clip, but when the Little Bits of the Cards get into focus, when they fly, it is very sharp there.
This setup can really produce nice Shallow depth of field!Also again, the colors look pretty good!.
You can always Close the Iris (apperture) of the Lens a bit, if you want a larger Depth of field. But if it is allready very dark, as in this case, that is propably not an option....

Looks really great and sharp. Though it almost looks like it was shot in 500fps and slowed down to look like 1,000, is that because of the motion blur?

I'm still a lens noob but is that motion blur effect caused by the F4 aperture or the 357 degree shutter?

That is just the (basically almost full) 360 degree Shutter, that makes everything look like that.
That is also the Reason, why the common reccomendation is to use 180 degree shutter. This gives some amount of motion blur, but not too much, also 180 degree Shutter was used in Cinema Movies for a very long time, so we are very much used to the look of it.
If you go far below 180 degree, like, lets say 18 degree, your individual Frames will look Sharper, but the clip istself wont look as Smooth. For Pans or Fast Camera Movements, also anything in The Frame that moves Quickly will Look choppy. This is often used in Action Scenes or other Very fast Scenes to make it look more intense or harsh (maybe not alway as extreme as 18 degree, maybe more like 90 or so).
If you go way above 180 degree, like here 360 degree, everything just blurs together and it also looks odd. Thats why 180 degree is mostly preferred for Cinematic Shooting.
For Science and such, there may be other factors that come into play when choosing an Shutter angle. For example, if you know there will be a lot of very fast moving Objects, and want to actually get Sharp images of those, while in the air, you want your Shutter angle as low as possible and so on...

Yes Marcus, it was shot at 1000 FPS, but I wanted to slow down the playback to see more detail.  This is 10 FPS, so 100 times slower than real life.
Nikon1 has nailed the 357 Degree blur effect description.

I was trying out some options and playing around with the shutter angle to increase exposure while keeping the gain on zero, and the lens on f4 for a little more depth of field.
If anyone can tell me how to make insects stay in my plane of focus I?d appreciate it!

Love the quality of the image at zero gain.  Will try higher settings today, and go back to narrow shutter angles for sharpness.

I guess luck is a factor and also to try and shoot a lot.
With my current camera i have only Pre-Trigger (Triggering the Recording bevore stuff happens, record time 3 Sec).
With The Chronos you could basically just hold the Cam onto insects all day long, and just push the Trigger, whenever something happens, which seems worth keeping. So that makes everything a lot easierer allready

That is my best guess, how some of those very good, very close up insect-Slowmo-Clips came to be.
Someone once said (in a Photography Magazine here in Germany) about an Award-Winning Picture of An Very small, vivid Frog in eye-Level Perspective of the Animal, that almost nobody can imagine how much patience an work goes into images like this.
So i think just keep shooting, you will get great shots eventually!

That's a really clean shot! Also to the people who are posting clips, do you guys use on-board compression? Like do you let the camera compress the files for you, or do you work with the raw file? I'm guessing raw file will result in better quality?

Excellent first tests, looks to be a really clean image that should perform well even at higher dB gain.  It is already crushing the best I have seen on my 1.4  ;D

Gain test, just increased the gain as the sun was getting lower, leaving FPS, shutter angle and lens aperture on the same(ish) settings.

Thanks!I dont know what is the Max Setting, but 24dB Still looks more than ok!Looking great.

I've never heard of dB gain when talking about video recording, what does this mean exactly?

Decibel or also known as dB is an logarithmic unit. Look it up, if you need more info about it. As far as i am aware, 2 dB more would Double your exposure.
Since the Native (Base-) ISO ?quivalent is ISO 500 on the Chronos 2.1, 24 dB Gain should be around 12000 ISO ?quivalent, if i didnt get something wrong here.
Will have to do an Side-By side Comparison with an other Camera, to be able to say this for sure, but i think that should be about right.

Ah I see yeah I noticed the iso change.

dB is decebel, a way to measure two relative signal strengths. In this case, 6dB of gain is equivalent to 1 stop, or a doubling of sensitivity. So 24db is four doublings, or 16x gain.

Thanks!I dont know what is the Max Setting, but 24dB Still looks more than ok!Looking great.

I find that 24dB gain on the 2.1 is about the same apparent noise as 0dB gain on the 1.4, the new sensor is really phenomenal with respect to noise!

So, 24dB would be 8000 ISO equivalent?

They're talking about the analog gain, which is measured in db.  Increasing it increases the brightness of the image, but also makes it more noisy/grainy.
