Chronos User Discussion / Re: Introducing Chronos 2.1 HD!

« on: April 08, 2019, 06:34:50 AM »

I Had to order one with the color sensor. I am also tempted to order second one with monochrome sensor but my wife would get even more angry so I think I have to pass that

The Chronos 1.4 has been really good for Youtube use but some of our customers that are ordering add videos etc. don't want to use 720p footage at all. But now I can still have my 1500€ high speed camera fee on final bill with out paying same amount for Phantom rental

General high-speed discussion / Optical flow and other "fake slow motion" tricks

« on: September 15, 2018, 06:55:25 AM »

I just realized that you don't need to buy any expensive plugins to generate missing frames to rise your frame rate in editing. Premier pro has this tool called optical flow that does just that. Here is example video that I made the first clips of each slow motion sequence are played out around 12.5 fps and the software generates every other frame to make that smooth 25 fps https://youtu.be/A6nvM7pYBGc?t=2m25s

I did also same trickery for some 500 fps footage out from 4k phantom camera and if you use 50% speed for the footage, have around 90 degree or faster shutter and simple background it seems to be working really well!

I think I try next to use this same tool for something like 15 000 fps chronos footage and try to make it 30 000 - 40 000 fps footage.

I think I should try out prime lenses that I have now here for the cameras if there is a difference. But in general we need zoom lenses on all cameras when we film since we don't have much time to use per one video, safety things also dictate camera placement and with high speed cameras the changing resolution makes things also bit hard. I try to always stay over 2 aperture since I think under that picture comes out always bit soft.

I was really surprised how well this weeks Chronos footage compares to our previous Smashinator videos that were filmed with +200 000€ Phantom setup. https://youtu.be/MYoBkIzkH1k

Sure it's bit nicer and with high frame rate but on Youtube use especially framerates bellow 3000fps are pretty damn nice.

Chronos User Discussion / Re: Lens/Camera protection

I shoot lot through polycarbonate and when it's new it doesn't effect the picture quality but it's quite soft material and scratches easily. So if you have to film lot through same shield it's good idea to make small window and replaceable smaller shield for that so you don't need to change hole big and expensive blast shield when it gets some scratches.

But if you have only bb's flying and maybe bouncing back I would fit just protective filter for the lens. The uv-filters are one option but there is more durable filters that are meant to be used as an shield's. And make sure that the camera doesn't fall from the hits and you should be ok My chronos has been hit quite many times with various shrapnel and it works just fine

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

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

Cheers,
Max

Yep it was v2512 with fast option and larges memory. Only problem was the finnish weather and short day 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 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.

At least with the Phantom cameras the limit when export difficulties start is 1 000 000 fps

We film usually couple videos per week with the Chronos but I really like this video that we filmed couple days ago

https://www.youtube.com/watch?v=XUYSOFStJ9c

We filled up some "balloons" with non newtonian fluid and shot them with the crossbow. I think I used something like 3000 fps on most of the shots.

I think I test with 3d-printed spacers under the lens that I have.

Then I have thought about testing with some stupid long lenses also. My dad has an old mirror telephoto lens for some film camera so using it with some adapter and small sensor of chronos would probably get stupid amount of zoom I think it's something like bit over 1000 mm for normal sized film. I will make video about the thing when I get the adapter for that purpose.

Chronos User Discussion / Macro lens suggestions

« on: June 15, 2017, 01:29:30 AM »

I have the general purpose 12.5-75mm lens for my Chronos and it's great for most of things that I film but I think I could use macro lens for some projects also. I think it would be good to have as short minimum focusing length since I am working sometimes quite small rooms so filming far away with lens that just zooms in with the small sensor isn't good option.
