Chronos User Discussion / Re: View recorded frame rate
« Last post by Rob_G on January 29, 2024, 04:54:20 PM »
Hello Beephe

If you save your videos in h.264 or TIFF format you can enable the overlay text feature.

After capturing a video, press the Play button, then the Settings button. Check the Text Overlay box. This feature remains enabled until you deselect it again.

Information about each frame’s position within the recording will be overlaid as well as the number of frames recorded.  The information appears at the bottom of each frame of compressed video or TIFF image. You can check the time difference between two contiguous frames to determine the interframe time. The inverse of this gives you the framerate.

This can be useful sometime later in case you forget the framerate used to capture your videos.

Unfortunately the latest Chronos firmware doesn't embed any metadata in MP4 files. However if you captured any DNG files, the shutter speed is included as metadata which might serve as a clue for recalling the frame rate.

If you were always shooting at the max fps, you could simply cross reference the resolution of each MP4 with the max frame rate your Chronos reports for each of those.

You might want to consider specifying a folder path or file name to include metadata such as the recording frame rate, however this is user error prone- it would require training yourself to verify the encoding settings dialog prior to each save

Chronos User Discussion / View recorded frame rate
« Last post by Beephe on January 28, 2024, 08:36:13 PM »
Hello everyone,

I did a bunch of test shots with different frame rates and now I can't remember which one was recorded at what frame rate. Is there a way to view that info in the file? I have the files saved as h.264 and the data I see is the playback frame rate (60 fps).
I appreciate the help!

I believe that although older versions of USB provided greater rates than eSATA, the most recent standards, such as Thunderbolt 4, and USB 3.1 Gen 2 (10 Gbps), have generally overtaken it.

There is not a connecting cable for the Samsung T5 SSD and the 1.4 and 2.1 Chronos cameras. Also, the firmware for the 1.4 and 2.1 Chronos cameras is not designed to operate with the Samsung T5 SSD. The camera itself cannot power the drive.

However, the Chronos cameras 1.4 and 2.1 can connect to a SanDisk 250GB SSD through an eSATA to SATA cable. The cable provides both data transfer as well as power through eSATA. If you are capturing video and recording it in an uncompressed video format, i.e. RAW, TIFF or Cinema DNG, it is the quickest saving option.

Hi AIIS,

Can you please describe how you are triggering and synchronizing the cameras?

I am interested in your setup

Hello AIIS,
 
I just want to add a quick comment to David's reply.

You can use the Shutter Gating function. With it you can control the exposure time. The exposure time is set by the duty cycle of your input pulse.

This gives you the ability to freeze the motion of the propeller.

If your external device allows you to add a time delay, you can even record single frames of the propeller at different angular positions.

One way to test if your camera is functioning correctly is to use a lower frame rate. Here you can adjust the frame rate to your liking. The camera needs more light than a standard camera because it starts with a high frame rate by default.
