Chronos User Discussion / Error: Windows Media Player Cannot play the file.

« on: October 20, 2023, 10:39:24 PM »

Intermittently, I have the following problem with my Chronos 1.4.  It saves out
files that my computer cannot read.  When I try to open them on my PC, I
get the below error message.  If I try re-saving on the Chronos, it continues
to give the same error message; in other words it is not fixable by simply
going into the Play menu of Chronos and re-saving it as another file.
   I am scared to death this is going to happen when I am running a very expensive
experiment.   
   FWIW, I have it set on H.264 format, 99.99 bits per pixel, and 1 as "saved file framerate".
   Please let me know how to prevent this from ever happening again.

Chronos User Discussion / Exposure time setting.

« on: October 01, 2023, 08:58:54 PM »

    I am running Chronos 1.4 with standard 12.5-75 zoom lens, f 1.2-16, 3.5ft-infinity focus.
I am running 12,578 frames per second and 320x320, 1x gain, .  My only question is:  What exposure-value
do you recommend using ?  According to the camera,
I can set the exposure to anything between 1 and 79.49 microseconds.  I think I have been using
about 14.7microseconds in the past.  But, what value should I be using ?  (The subject is a projectile at 2400 feet/second.)

Chronos User Discussion / How to convert "Saved File Framerate" on an existing mp4 file?

« on: May 20, 2020, 09:40:59 PM »

Can the chronos 1.4 take an existing mp4 file and save it back out to the SD-card at a *different* "Saved File Framerate"
than the mp4 was originally saved as?
