IO-Data GV-USB2: 112 Driver Minimum Capture fps is 50?

[Alwyn]

Just noticed, after upgrading from the 111 driver to the 112 driver, there is no selection for 720x576 25fps. The minimum available was 50fps.

Can someone else confirm this?

I reverted to the 111 driver and 25fps became available.

Thanks!

May I ask where do you get these numbers 111 and 112 from?
Windows 11 Device Manager returns it like 1.1.0.93 in my case (with no problems btw). Would you call this 110 then?

From the IOData website:

https://www.iodata.jp/lib/software/g/1780.htm#Windows%2011

The displayed driver numbers are a bit weird. The full driver number is in the capture software Device Settings, and the dates (2010 for 111, 2021 for 112) is in Windows Device Manager Properties. See:

Did you by chance capture your cine8 in the other thread with the driver "112"? I was confused how the .avi file was reported by mediainfo and how it looked when separating fields (I am not talking about the shutter issue). What was the framerate / fieldrate really?

[Alwyn]

I don't recall, Starc. Many files of many resolutions and framerates have crossed my keyboard lately!

It looks like your Canon (CMOS) recorded at 25 frames per second / 50 fields per second, while your Panasonic (CCD) recorded at 50 frames per second /100 fields per second.
So all ok with the capture drivers and settings it seems. My bad.

A fair chunk of those files were captured with my Startech USB3HDCAP; I can't say which ones exactly.

If your GV-USB2 driver is dated 7/6/21 in Device Manager, do you have an AmarecTV preset of 720x576 25fps?

[Sharc]

I am using the driver which was shipped with the device. Works perfectly. I can set the Proc Amp etc. No reason for upgrading.

Windows 11: 1.1.0.93 28.06.2010
AmarecTV 3.10: 1.1.0.93.5, 2010/06/28

Thanks. I'm just asking, not telling.
