Two windows opened, one showing the running record time etc. and the other the camera window image.
Unhappily, when I reconnected the camcorder to re-test today, the second window with the camera image did not longer open!! I've tried to reset the machine and camcorder, but no. Did also a test with system ffplay (when the v4l2 was free again) and it worked. Obviously here is something that causes this confusing issue, but what? load straty, a changed setting or something else? Happily the window opened yesterday, so I know the should work.

There is checkbox named Monitor Video. Be sure you have it set. I usually set all parameters (like frame size, framerate, type of Video Input device) in Recording tab. Note that in your case while you record SD it gets upscaled by your svideo -> hdmi and hdmi to usb converters to 1080p50 There is red button and above it filename input field. Put path/filename there, hit Record, and it should start recording to that file. In case you played with contrast/brightness settings (cingg uses its own set for v4l devices) you can run guvcview and restore them to their default values

Note that in your case while you record SD it gets upscaled by your svideo -> hdmi and hdmi to usb converters to 1080p50
There is red button and above it filename input field. Put path/filename there, hit Record, and it should start recording to that file.
In case you played with contrast/brightness settings (cingg uses its own set for v4l devices) you can run guvcview and restore them to their default values

I tried to Record camcorder video stream via v4l2 and hdmi-usb3 capture as input device.
ms2130 is more powerful but else similar to the usb2 EasyCap device example described in the CinGG manual
https://cinelerra-gg.org/download/CinelerraGG_Manual/Use_Case_1_a_EasyCap.ht...
My Sony FX7-E 1080i50 HDV camcorder was connected via HDMI to a ms2130
usb3 capture card.

1) Settings > Preferences > Record
File format: FFMPEG mp4
Video In:
Record driver: Video4Linux2 /dev(video0
The first thing I noticed was that default Record video setting was SD
NTSC, not PAL as else according to my time zone.
Could this possibly be changed as else?
Frames to record on disk: 30 (default)?
Changed frame to a camcorder resolution and fps supported by v4l2 and ms2130:
Frame: 1920 x 1080 (was default NTSC SD) fps: 50 (progressive)
File > Record r
Two windows opened, one showing the running record time etc. and the other the camera window image.
Unhappily, when I reconnected the camcorder to re-test today, the second window with the camera image did not longer open!! I've tried to reset the machine and camcorder, but no. Did also a test with system ffplay (when the v4l2 was free again) and it worked.
Obviously here is something that causes this confusing issue, but what? load straty, a changed setting or something else? Happily the window opened yesterday, so I know the should work. I understand this can be difficult to troubleshoot without a similar setup.
There is checkbox named Monitor Video. Be sure you have it set.
Yes, thanks it works again.
I usually set all parameters (like frame size, framerate, type of Video Input device) in Recording tab.
Yes, but I wonder what these default box values mean?
Frames to record to disk at a time: 30 Frames to buffer in device: 2 Positioning: Software timing I left first two as defaults, and sometimes for screenrecording set Samples instead of Software timing (so it will write stream relative to audio samples, adding or dropping frames as needed - makes audio and video track match)
There should be std. for cingg wrench icon where you select type of encoding (FFMPEG ..). If you click it you get window with compression parameters. I set Pixels there.
Yeah, thank you - now it's hopefully better in my fingers :)
First, with my Sony FX7E HDV 1080i50 camera connected via HDMI-ms2130-USB3 - 4vl2
That is the camera's EIP native (w/o MPEG-2 compression) output via HDMI handshake expected FHD 1080i 422, or is it just the ms2130 via USB3 and v4l2 capability that is detected below?
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). Unless you set your camera as giant "webcam" I think that is on HDMI output is result of decoding mpeg2 from tape?

Unless you set your camera as giant "webcam" I think that is on HDMI output is result of decoding mpeg2 from tape?
My tests here were just camera without tape. I'll have a look with tape playing to find the bitrate over HDMI out. And to repeat the relevant sections from to Steve Mullen's FX7 and V1 handbook: When the camera is operating, the EIP generates uncompressed 1440x1080i with a 4:2:2 color space. Digital 4:2:2 data are output via the HDMI port Therefore, you can record 4:2:2 live HD video from the camera without MPEG-2 compression. Two-channel audio is output on the HDMI port, both when the camera is running and during tape playback. The Sony V1 and FX7 provide an HDMI output port that carries uncompressed 4:2:2, 8-bit, digital video plus dual-channel, PCM, 16-bit, 48kHz audio. If you record to HDV tape, you can also benefit from HDMI uncompressed capture and editing. After MPEG-2 decoding, the 4:2:2, 8-bit YCbCr uncompressed video is sent via the camcorder’s HDMI port 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. The HDMI chip downscales 1440 to 1280 while it up-scales 540 to 720. The result is 720p50 or 720p60, which is output via HDMI.

Yeah, thank you - now it's hopefully better in my fingers :)
First, with my Sony FX7E HDV 1080i50 camera connected via HDMI-ms2130-USB3 - 4vl2
That is the camera's EIP native (w/o MPEG-2 compression) output via HDMI handshake expected FHD 1080i 422, or is it just the ms2130 via USB3 and v4l2 capability that is detected below?
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).
Unless you set your camera as giant "webcam" I think that is on HDMI output is result of decoding mpeg2 from tape?
My tests here were just camera without tape. I'll have a look with tape playing to find the bitrate over HDMI out.

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

The first thing I noticed was that default Record video setting was SD
NTSC, not PAL as else according to my time zone.
Could this possibly be changed as else?
Frames to record on disk: 30 (default)?
Changed frame to a camcorder resolution and fps supported by v4l2 and ms2130:

Two windows opened, one showing the running record time etc. and the other the camera window image.
Unhappily, when I reconnected the camcorder to re-test today, the second window with the camera image did not longer open!! I've tried to reset the machine and camcorder, but no. Did also a test with system ffplay (when the v4l2 was free again) and it worked.
Obviously here is something that causes this confusing issue, but what? load straty, a changed setting or something else? Happily the window opened yesterday, so I know the should work. I understand this can be difficult to troubleshoot without a similar setup.
There is checkbox named Monitor Video. Be sure you have it set.
Yes, thanks it works again.
I usually set all parameters (like frame size, framerate, type of Video Input device) in Recording tab.
Yes, but I wonder what these default box values mean?
Frames to record to disk at a time: 30 Frames to buffer in device: 2 Positioning: Software timing I left first two as defaults, and sometimes for screenrecording set Samples instead of Software timing (so it will write stream relative to audio samples, adding or dropping frames as needed - makes audio and video track match)
There should be std. for cingg wrench icon where you select type of encoding (FFMPEG ..). If you click it you get window with compression parameters. I set Pixels there.
Yeah, thank you - now it's hopefully better in my fingers :)

CinGG_Record2.mkv Duration: 00:00:13.66, start: -0.007000, bitrate: 890 kb/s Stream #0:0: Video: vp9 (Profile 0), yuv420p(tv, bt709/unknown/unknown), 1920x1080, 50 fps, 50 tbr, 1k tbn
CinGG_Record3.mpeg Duration: 00:00:22.26, start: 0.520000, bitrate: 2321 kb/s Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt709/unknown/unknown, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn
Note that in your case while you record SD it gets upscaled by your svideo -> hdmi and hdmi to usb converters to 1080p50
There is red button and above it filename input field. Put path/filename there, hit Record, and it should start recording to that file.
In case you played with contrast/brightness settings (cingg uses its own set for v4l devices) you can run guvcview and restore them to their default values
