I will be back in Germany from the next week onwards and still can provide a Chronos to test with. Location in Germany varies though ;)

Your footage is amazing! Did you follow the first rocket manually or do you have a jig with some kind of actuator that pans the camera?

Thanks, the cameras pitch automatically based on the rockets acceleration and liftoff is detected with a switch on the rail.

Great footage! Could you please post a picture of your pitching system? It sounds interesting!

As far as I know, the video displayed on the screen is the unencoded data directly from the RAM buffer.
The h.264 encoding done to store the non-raw data is a lossy compression, and therefore can't look exactly like the original.

Nice! I'm planning to do similar shots but could not be bothered to set them up yet. Also those insects are fast!

Awesome, updated just fine and all the features are there. Only weird thing I could see is under "About" it still says RC1, made me do a double take after the update. Thanks for features and fixes!
Same here.
This was actually the first update which completed on it's own ;)

This is a known bug in the 0.3RC1 software, if you are using it:
RC1 known bugs:
-On some cameras, a small number of recorded frames are corrupted (about 1 in every few thousand). Most cameras do seem to exhibit this problem. Fix is in progress, this post will be updated when a fix is available.

Here's a quick and dirty way to do it in post using ffmpeg stolen from another thread:
Yeah, the first thing I do with the files is use FFMPEG to slow the play rate from 60fps to 30fps, and also to add a time marker to each frame.  For example, here's the command to do that on a 640x120 clip (17424 being the fps):
Code: [Select]
ffmpeg -i ChronosFile1.mp4 -r 30
 -vf "setpts=(2/1)*PTS,
 drawtext=fontfile=Arial.ttf: expansion=normal:
   text='%{eif\:n*1000/17424\:d}.%{eif\:mod(n*1000/17424*100,100)\:d\:2}ms':
   x=(w-tw-5): y=5: fontcolor=white: box=1: boxcolor=0x00000099: fontsize=25"
 -an -y ChronosFile1Post.mp4

I also had this a few times and I found that it happens less if you don't put a memory card in before or during boot.
might be coincidental or confirmation bias though  ;)

The jog wheel can do two things: spin and click.
I figure the logical thing to do is keep having an unpressed spin cycle the value a little, and a pressed spin cycle the value a lot. Like on the Play screen. However, if you just click the wheel without spinning it, it'll pop you out of the control you're editing so you can select a different control or button. Click the jog wheel again to edit the new control or click the button.
I think this is the most natural and intuitive way to do it, so looking forward to it. However please try to keep the different option windows (recording, saving, trigger settings...) somewhat consistent in their design and orientation. For example a general left to right or preferably up to down direction for the user inter-actable items. You should not be surprised which input field is going to be selected next by rolling the wheel and they should not jump around too much :)

This is the link to the ram I bought, happy upgrading
Same with me, works great. Having 32GB is definitively a large improvement.

Is the RAM user expandable? Does opening up the camera void the warranty?
Should be User Upgradable from what i have heard in other threads here in the Forum (I dont have a Chronos yet).
Should also be quite easy.
But i realy dont konw about the Warranty.
Someone else here should know.
While it certainly wasn't hard, easy is not the correct word for changing the RAM  ;)
has someone already done a teardown on YouTube or somewhere? There you should be able to see how hard it is. If no one has done a video like this and if there's enough demand I'd be willing to do one myself.
