Chronos V0.3.1 Beta - Updated Oct 15 2018 with beta-9

<< < (2/12) > >>

NiNeff:
I've now had a chance to test the beta quickly.
Here are my first impresions:

 - Gernerally smooth updateprocess and it feels great to use.
 - YAY! HDMI!  :) :) :) :) Had no issues at all, recoring in different resolutions and playing back works fine!
 - maybe display the "saving" info also on the HDMI output if possible instead of a black screen
 - The Jog-Wheel select is a great addition, but it is really hard to see what is currently selected. Please make the highlight more pronounced, especially if a text-enty field is selected instead of a button, you can barely make it out.
 - The direction in which the UI elements are scrolled through with the Jog-Wheel differ from screen to screen and just feel inconsistent. If I turn the wheel to the right I'm expecting the "cursor" to go to the right in general.
 - Frame Overlay is a great addition!
 - The Preset-Resolutions are wierdly offset to the top
 - The font in the UI screens is not acually black but you can see the videofeed throuh them. I tried to take a picture of it but it really only is visible in motion. Maybe you set the alpha channel to zero by accident? It is very prominent on the Radioboxes, as they are a larger "hole" throuh the UI.
 - The Focus Aid almost always has as a solid line to the left of the screen. I guess this is inherent to it's design as the line dissapears if you're filming darker colors. This might be avoidable if you copy the left most lines to an invisible bufferzone bevore running the edge-detection. Probably not worth the hassle.
 - The whitebalace should not be set to Tungsten as default. Maybe use Average Daylight?
 - add a quit/canel button to all tabs of the Utils menu...
 - It would be really great to be able to click the wheel in the main menu to start/stop the recording!

Here's a video of the translucent UI: https://youtu.be/CraeQdpt9ck
Also: the Demo mode could be enabled by default and just always add the "Play" button to the "Play" Screen, but rename it to "Loop". I had to fiddle around quite a bit to realize how the demo mode works and where to find it ;)

Dan Kanes:
This is AWESOME!

Three crazy questions for you:

1. On your next camera can you have the main ram be based on intel Optane... Look how cheap these are:

2. What can I do to speed up saving exports ? like will it be faster to save over Gig-E? Is ESATA working ?

3. I'm getting arouns 1fps saving to a USB 3.0 stick... does that sound right?

Dan Kanes:
Added feedback:

saving TIFFs or CinemaDNG to USB Drive results in zero byte files, and the unprompted ejection of the USB media.

both seem to work fine for me to SD Card at the moment.

Hey Dan,

Right now the fastest saving method is via the eSATA port, which can typically sustain write speeds of about 60MB/s before the CPU runs out of speed, or about 25fps when saving raw at 1280x1024. To use this method you will need a 5V SATA drive (this includes almost all 2.5" drives), and an eSATA+power cable such as these available from Monoprice or Amazon

As for USB flash drives, I have quite a few cheap USB drives that exhibit absolutely terrible write performance (as low as 1fps as you have commented), as far as I can tell it seems to vary quite widely as to how well they perform under heavy write loads.
