Chronos User Discussion / Re: Let's talk lighting
« on: September 15, 2017, 04:29:16 PM »
I've been using one of the Stratus LEDs with a benchtop power supply. It's plenty bright, but a real hassle to power. My PS only supplies 5.1A, which is barely enough. The other option is a pre-made 24v 7A wall wart, but I'd probably have to order 5 or 6 of the things to find one that doesn't induce flicker.

They have a wall wart on their site, but it's not yet available for sale. In the meantime they suggest a 6s hobby LiPo, but that means buying another charger, not to mention the need to recharge every hour.

I'm seriously considering that Godox.

Chronos User Discussion / Re: How to manually set the fps?

Haven't tried it yet, I'm sure it works. But I've been thinking about it more.

Generally, shouldn't a value be written once the field's focus is lost? Or at the very least, shouldn't all currently displayed values be written upon OK press?

One of these days I'm going to have some super compelling idea. Right now though, I'm just screwing around. :)

Did you press enter after setting your frame rate?

oops. ;)

Chronos User Discussion / How to manually set the fps?

I tried today to shoot 1280x1024 at 1,000fps and couldn't get the setting to stick. No matter what I typed into the fps box, the main screen would always revert to 1.5kfps.

What am I missing?

Had to upload full video to keep it at the best quality possible

But, why? Mark in, Mark out, Save?

And, regarding the video itself ... jeeeezus! I want one of those. :)

Chronos User Discussion / Best Save-As frame rate?
« on: September 12, 2017, 11:04:22 PM »
Was watching https://www.youtube.com/watch?v=71t_MCJ2_XI and realized that saving at 60fps (the Chronos default) might not be the best option. Do we actually want to save a 1000fps shot at 1000fps and slow it down in post? Save at 30fps (which removes the ability to speed it up later)? Or is 60fps some sort of happy medium? Still learning, be gentle. :)

Chronos User Discussion / Re: Need a tutorial on shutter speed
« on: September 09, 2017, 12:48:08 PM »
so 2x or 180 degrees would be 50% shutter. 100% would be equivalent to 360 degrees.

I think that's why some of my fast-moving subjects, like the pellet in my most recent trial, are stretched; the shutter is open too long per frame, allowing motion blur.

Armed with that explanation, I don't think it needs to change yet. I just didn't know how to use it, will try a few more settings.

Should have lowered the shutter speed (I think?), but need more light.

Chronos User Discussion / Need a tutorial on shutter speed
« on: September 09, 2017, 10:04:22 AM »
In looking around, I'm learning that shutter speed is crucial for getting good hi-speed footage. There's much talk of ensuring that one's shutter speed is 2x the frame rate, or the 180* rule, and other suggestions. The problem is that the Chronos displays shutter speed in us, and I'm not sure what that scale is. How does us relate to whole seconds or fractions of a second? There's also %, which is a percent of ... what? Setting shutter speed to MAX can't be correct in all scenarios.

It's almost like trying to figure out one's fuel efficiency in miles-per-gallon, but only given a distance in feet and a speed in Kilometers-per-day. It's certainly possible, but stupid to not start with relative value.

There must be a simpler way to show shutter speed on the Chronos. Does the UI need to be changed to use a different scale? If not, I need a good tutorial on how the shutter speed on THIS camera relates to time and/or frame rate.

Chronos User Discussion / SD card size?
« on: September 04, 2017, 11:47:38 AM »
I've read up on SD speeds and have narrowed down my choices. But how big are the files saved to the card? How much space is needed for, say, one 8 second clip at max resolution? Max frame rate? Should I be looking for 8gb cards? 64? 128?
