Hi Raphel,

The DeviceStatus was developed with Qt Creator, with as the project file. The QDialog library is part of Qt infrastructure.

To build within Visual Studio, I suggest referring to the Qt VS Tools guide at

Decklink 8k pro SDK whether support recording the 8K video?

PostThu Mar 11, 2021 6:44 am

Dear Cameron,

Thanks for your support, I encountered a question that it can record the 2k video which duration is over 1min, but not in 4k or 8k video. And it will only less 2s when I start the record function, please refer to the below picture.
At the begining, I think the short HDD capacity lead to the issue, then I expanded the HDD capacity to 34G and it also occurred the above issue.
So please give me some suggestion for the issue. Thanks again.

Best Regards!
