First, with my Sony FX7E HDV 1080i50 camera connected
via <br>
HDMI-ms2130-USB3 - 4vl2<br>
<br>
That is the camera's EIP native (w/o MPEG-2 compression)
output via HDMI <br>
handshake expected FHD 1080i 422,<br>
or is it just the ms2130 via USB3 and v4l2 capability
that is detected <br>
below?<br>

<div dir="auto">Very good question. HDMI is (uncompressed)
digital video interface, likewise USB3 is also digital, BUT
as we noted in another thread by default ms2130 does its own
signal processing, but with hacked firmware this can be
disabled and thus this usb3 dongle become sort of generic
digital input device at relatively high speed (75 Mbytes/s).</div>
<div dir="auto"><br>
</div>
<div dir="auto">Unless you set your camera as giant "webcam" I
think that is on HDMI output is result of decoding mpeg2
from tape? <br>

<br>
My tests here were just camera without tape. I'll have a look with
tape playing to find the bitrate over HDMI out.<br>

And to repeat the relevant sections from to Steve Mullen's FX7 and
V1 handbook:<br>
<br>
When the camera is operating, the EIP generates uncompressed
1440x1080i with a 4:2:2 color space.<br>
Digital 4:2:2 data are output via the HDMI port <br>
Therefore, you can record 4:2:2 live HD video from the camera
without MPEG-2 compression.<br>
<br>
Two-channel audio is output on the HDMI port, both when the camera
is running and during tape<br>
playback.<br>
The Sony V1 and FX7 provide an HDMI output port that carries
uncompressed 4:2:2, 8-bit,<br>
digital video plus dual-channel, PCM, 16-bit, 48kHz audio. <br>
<br>
If you record to HDV tape, you can also benefit from HDMI
uncompressed capture and editing.<br>
After MPEG-2 decoding, the 4:2:2, 8-bit YCbCr uncompressed video
is sent via the camcorder’s<br>
HDMI port<br>
<br>
If you are playing a 1080i50 or 1080i60 HDV tape. The 4:2:0 MPEG-2
is decoded and chroma up-scaled to a 4:2:2. <br>
The HDMI chip downscales 1440 to 1280 while it up-scales 540 to
720. <br>
The result is 720p50 or 720p60, which is output via HDMI.<br>
