There are many parameter characteristic for your choice as below

Video scaler distortion:
we wish the video do not have any distortion.
But, the hdmi have many kind of resolution and UVC output also have many kind of resolution.
Some software can not choose the uvc output resolution.
if we do not add the video scaler ic , it do not easy to use
because hdmi input resolution/ frame rate must be equal the UVC output resolution and frame rate
hdmi source: 1920x1080p 60fps
uvc hdmi capture card have 1920x1080p , 1280x720p , 720x480p uvc output.
SKYPE always get 1280x720p uvc
For this case, hdmi input do not equal uvc output.
if we do not add the video scaler ic, it do not have any video.
After add the video scaler ic , it become the Independence between HDMI INPUT and UVC output.
But, it will occur the video scaler distortion
it is a trade off !!
