Hi everyone!  :)

I filmed some different types of fireworks.

In the beginning, I had some troubles with the quality on youtube when I uploaded in 720p, then I switched to 1080p.
Here is the playlist so far, more to come:

In retrospect, I should have placed the camera to the side to avoid having too much light come through the bullet hole. Next time.

Here's a quick one, a great shot (scientifically speaking - resolution is low) showing a shock wave produced by an explosive target.

As a bonus, the shadow of the shock wave is also visible. As the shock wave moves through the air and compresses that region, the refractive index of the air changes, making it act like a lens. This is what causes this shadow to be visible.
Or something like that.

I often find the joy of filming in high speed is finding out that you've inadvertently captured something after the fact. There's so much to look at in even a short clip. I love it.

Sand and paint on a drum.  Mostly testing using realtime and high speed footage together and sound.

There is a series with electrical arcs coming up soon.

Abuse in the process of mixing concrete.

We were filming somethings couple weeks ago with big and expensive phantom camera but the chronos footage turned out also surprisingly good on this 5 meter long stick of dynamite video https://youtu.be/ThLtMhiak-Q

The chronos footage starts on 8:20

Various shots of bullets being fired and striking a variety of things:

I was wondering, What model phantom were you filming with? I recall you saying "the best one" Would that be a v2512?

Cheers,

There are colored lines visible some times. I know this can happen when the memory is cold, but it was about 16 °C, which I wouldn't consider cold. Is there any way to prevent this? I plan to do some more filming in early January, and don't want all of the footage to show these lines.

Hey :)

Did you film using the battery or was the Chronos plugged into a power outlet there?
If it's been on an outlet: maybe there are things on the same grid which introduce small linespikes and result in such artifacts?

All the best
Martin

Yep it was v2512 with fast option and larges memory. Only problem was the finnish weather and short day :D But I got funding for the camera with really short notice and it's just couple days in country when you order that so you get the weather that happens to be on filming day. We actually filmed this week also one day with the thing since one of my friends customer needed 80 000 fps camera so they had to rent that one again and they needed it only for one day and I got the second day really cheap since minium rent period is two days.

This time we did some DIY shaped charges and 70 litre gasoline bomb :D The shaped charges looked quite nice with the phantom but I got also really nice clip with the chronos from gasoline bomb. I am publishing that video tommorow and I can add link here when it's out.

But in generally I think that the v2512 phantom and chronos are good match for youtube videos. You can take clip from small details with really high frame rate with the phantom and then wider shot with chronos with speed aronud 1000-3000fps. I am probably filming next time when it's bit more light or if I get somebody else to pay for the phantom.

I think this is also really nice shot https://youtu.be/HcTRapGoHK8?t=3m43s
It's the same reaction filmed with two chronos cameras, color version and black and white. I had color version recording 500fps to get more light and black and white little bit faster. I think I could do better now since this was my first video with the black and white model and I didn't know how to exactly set it up to get best possible picture.

Here are more blast waves in slow motion at 8250 and 7400 fps, one hitting a snowman and the other some propped up dry plant stems.

Some of you may be reminded of the artificial forest created in Nevada in the 50s for one of the atomic tests :-)
