Capture with Blackmagic Mini Recorder problems

[Gyetvai Gabor]

We use a Debut Video Capture 5.26 Pro on Windows 10 Pro (core i5 8th gen) with a Blackmagic DeckLink Mini Recorder card.
We use this one as a compliance recorder in a smaller television to record the on air directly from their SDI output.
The first issue what I faced, that the device is not shown under the capture devices, but It can be seen as a webcam, so It's not a big problem.
Unfortunately I can't record in our television format (1080 50i or 50p or 25p), because there was no preview from the device. Other software can handle this resoultion like vMix, but i'd like to use Debut, because of the slicing and the scheduled recordings. I was only able to set It up in SD (720*576 50fps). It's not a big problem, because we need this recording to show authorities that the channel logo was shown, and the age rating is apropiate.
But I would be nice to have the option to record in the native resolution or near to that to use It as archive. (1080p25 would be great).

Are there any plan to include the Blackmagic/Decklink cards and usb devices using their SDK to be able to use as a real capture device?
Is there a list of supported capture devices? I can only find the VIDUSB2 in the list, which has no digital interface...

The problem is that we want to use the software 24/7 with 1 hour slices, but we faced problems: 
- at the first try we used the default .avi settings with H.264 native settings with mp3 sound
at this point after an amount of time we faced an issue with the sound. If I play the whole video there is no issue, but If I want to play the video from the second half of the footage, then there is no sound at all. If I convert the video into an another format with prism, then the sound is ok. So we had to change the settings to ffmpeg.

Have you seen this issue with the sound?

 

Now we have an another problems:

sometimes It shows the "Error starting screen capture Retry". This is very strange, because I don't want to record the screen, I want to use the "webcam".

Have you seen this error? What can cause this? The card is PCIe, not usb, so It can't be unplugged very easy.

The another error message which is very strange: major deviation between the time length of the recording (01:00:00:00:000) and the actual recording time (45:01:31:813) is detected. Do you want to use system clock for this camera from now on?
I haven't find any option in the software to set which clock I want to use. Where can I find It?

And also the software unexpectedly stops recording and not starting another. How can I check what was the cause? Are there any kind of logging for this?

I want to upgrade to the most recent version of Debut, because mine is nearly 2 years old, and I want to check what new features and bugs were fixed since. Where can I find the release notes?

 

Thank you for your kind help and response! 

Bests,
Gábor.
