Hi everybody, I've just read a new chipset was released. It is Ms2130 and it seems to provide good outcomes for those low budget Hdmi capture cards.
The previous cards were equiped with a Ms2109 chipset which allows you to capture Hdmi at 1080p 30fps MJPEG. It has a Usb 2.0 plug.
Now with the Ms2130 chipset you can capture up to 1080p 60fps YUV ! Thanks to the Usb 3.0 plug. The actual price is around $20 on Aliexpress.
Main chip – MacroSilicon/UltraSemi MS2130 USB 3.2 Gen 1 high-definition video and audio acquisition chip
HDMI input up to 4Kp30, 24/30/36-bit depth color
Video Output up to 1080p60 in YUV or JPEG output format
Audio – L-PCM codec
Input cable length – Up to 15 meters with a standard AWG26 HDMI cable
Power Consumption – 1W max (5V @ 0.2A)
Dimensions – 52 x 25 x 14 mm
Weight – 15.6 grams
Temperature Range – -10 to +55℃
Have you already tried this new capture card ? Do you think the result is good ?

Do they support 480i29.97 and 576i25 properly? The MS2130 is a bit unclear, says 720× 576 and 720× 480 at 60, 50, 30, 20 and 10 hz.
Hi, here is the video output resolutions table according the Usb port you use :
If I understand correctly, and based from my experience with the Ms2109 chipset you can have, 480p30 (YUV) and 576p25 (YUV). I don't think you can have interlace, only progressive (based on Ms2109)

Low end to middling, underpowered and UVA, UVC usually
They are a new fab that is kind of slowly coming up to speed.
Last gen of chips forgot, or hadn't reached HDCP compliance yet
This looks like their first 4K effort in a usb stick
As cheap as it is.. somebody will be interested, but since its 4K and hits the target market.. they will probably start out at a premium price for dongles and come down after that. Might stay a little high until someone finds a reason for 8K to go mainstream.
Pay attention to the latency .. it won't be good for gamers or twichies
I don't see it on their home page yet, so I guess their website isn't up to date yet.. or maybe they've been sold or consolidated with another China company.. that tends to happen at a whim of the ruling party.
That github site seems to have a lot of protoboard projects using many MacroSilicon chips, wonder if its the development wing behind MacroSilicon since they seem to originate many documents available no where else.
Embedding UVA, UVC capability means no drivers since its among the oldest of protocols built into an out of box bus support in Windows and OSX. The implementation by MacroSilicon in the past has been somewhat limited and very slow to respond on power up. I wonder if they using 8051 micrcontrollers speed up many orders of magnitude again for the pseudo cpu to handle the UVA requests and replies.. it leads to some operating systems assuming its not there, or has dropped off the bus.. so they appear to come and go depending on the operating system and its hardware. - i assume each generation they gain more experience and the next gen will be a little better. sooner or later to reach HDMI 1.4 however they will have to add in HDCP.. and that has plus and minuses to their bottom line. Mostly these sorts of chips should target 4:4:4 video cameras since they are suppose to have non-HDCP mode.. but eh.. that's a very small market. Maybe? streamers can afford those cameras these days? Super resolution webcams ? UVA, UVC would make sense.. all you need is a CCD then. Hi resolution back up cams? LCD TV's that watch you? Outdoor webcams for security?
UVA, UVC dumbs down a lot of the controls over the video signal processing into simple static standards compliance digital video (709 ?) so no aspect ratio correction, no proc-amp controls, no tbc, no frame sync.. has to make the requests and replies as simple as possible to fit the protocol. Since 2009 and most things have gone digital.. more and more the source is assumed to be already corrected.. so these are more or less just bit shifters. I think UVC 1.3 was the last update and it only got an h.264 option added to the protocol. Its a really really old protocol.
The closet analogy would be an SDI to USB video capture device.. which is stretching the meaning.. its really just converting a static bit stream from one protocol to another. Since it doesn't have to handle SD analog signals, it just has to be fast.
Again, pay attention to the latency.. 6 to 11 frames.. if your a gamer.. for-gett-a-bout it.
Not saying they won't grow up to make something really useful, EMPIA took years to come to an all in one chip and its still around but that targeted SD.. this is an HD and Beyond chip.

I bought the MS2130-based capture card. Max output is 1920x1080@60. Capable of YUV2. Unfortunately, unlike the MS2109, this one does not bypass HDCP so it doesn't work with my PS3.
If you're into experimenting, one of these gadgets bypasses HDCP from HDMI for me. I use this particular one to pass HDMI from my Panasonic DVD recorder to my Startech HDMI digitiser, which would otherwise block any HDMI signal flow.
It's currently unavailable but keep an eye out.
Just a note that according to multiple reports, these MS2130 sticks mess with the video signal.
Always 1 pixel of black at top, 1 pixel cropped at bottom:
Here three users discuss this. One demonstrates that in addition to the shift downward, there seems to be subpixel scaling.
Apparently chroma is modified, requiring a Proc Amp adjustment to approximate the original signal: https://twitter.com/MateuszStarzak/status/1589677507187707905?s=20
