Chronos User Discussion / Fan running much faster?
« on: February 17, 2018, 10:59:45 PM »
Is anyone else's fan running much faster/louder with the last two beta updates? I'll admit that I haven't used my camera in a couple months, but I don't remember it being so jet-engine-ey the last time I powered it up.

Were there any changes in the fan controller that could explain it? Or am I just nuts?

Software Dev / Saving setting across reboots is BAD
« on: December 30, 2017, 11:36:19 AM »
The last three times I've used my camera, I've been troubled by how dark, how tightly framed, how unusable the view was. "Oh right, this is set up for the last shot I did a week ago, with settings that are in no way applicable to this shot." The requirement to manually and studiously reset the camera to a known-good zero point is ridiculous.

Saving settings across reboots might be nice for lab environments, but I don't feel that that's this camera's primary scenario. It's small, light, battery powered, untethered, super mobile, designed for faster deployment than others can ever hope for. The default state should allow for fast power-up-and-shoot with the least fiddling as possible. The default state should be one which offers the best chance of "getting the shot" with no double-checking. That is: full frame, full shutter, 0 gain.

Please add an advanced toggle to save settings across power cycles. I can certainly see the value when shooting in the field for long periods of time, having to change batteries, waiting for weather to clear, etc.

But as a default, it's horrible. The first step when powering on the camera should not be "go though every setting and put it back to normal so I can build up from the known-zero point."

In short, allow people to use the camera as they like. If people like the saved settings, great! But don't force the default which requires all other users to "fix" the settings from last week before embarking on a new shooting scenario today.

Software Dev / Software v0.3?

I'm bored, so thought I'd harass David. :) Any idea when the next software rev might be coming, and what might be included?

Chronos User Discussion / What will the HDMI output resolution be?
« on: September 23, 2017, 05:39:21 PM »
I'm looking at building a portable external monitor, and most of the screens/drivers do not include scalers. What resolution will be coming out of the HDMI port?

Chronos User Discussion / Segmented buffer?
« on: September 22, 2017, 06:32:22 PM »
Thinking aloud... User option to split buffer in half (two 4-second buffers, for example)

1) Shoot video to bufferA (invisible to user), Play, Mark in/out, Save
    UI returns to record screen
2) Immediately shoot video to bufferB, Play, Mark in/out, Save
3) Shoot again to bufferA, which has since emptied

The user would be able to shoot new (shorter) videos almost constantly, assuming s/he had chosen the Split Buffer option. This would all be transparent to the user, unless bufferA or B was yet unfinished with its save (gray out the Record button, with countdown or nnn% ?)

Chronos User Discussion / Filming a welder?
« on: September 21, 2017, 03:14:02 PM »
With the recent eclipse, we were all inundated with "don't look at the sun" of course, but there were also a lot of warnings about using protective films/filters over camera lenses.

How might the sun relate to a welder? Safe to point the Chronos sensor at such a bright spot?

Chronos User Discussion / How to manually set the fps?
« on: September 14, 2017, 06:39:27 PM »
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?

Chronos User Discussion / Best Save-As frame rate?
« on: September 12, 2017, 11:04:22 PM »
Was watching 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 / 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?
