I found some test patterns (clips) ...

http://www.gvgdevelopers.com/concrete/products/k2/test_clips/ in particular I look at http://www.gvgdevelopers.com/K2DevGuide/Clips2/NTSC_SD_DVCAM_colorbar.mov interestingly this one says: Video ID : 1 Format : DV Codec ID : dvc Duration : 10 s 10 ms Bit rate mode : Constant Bit rate : 24.4 Mb/s Width : 720 pixels Clean aperture width : 704 pixels Height : 480 pixels Clean aperture height : 480 pixels Display aspect ratio : 4:3 Original display aspect ratio : 4:3 Clean aperture display aspect ratio : 4:3 Frame rate mode : Constant Frame rate : 29.970 (29970/1000) FPS Standard : NTSC Color space : YUV Chroma subsampling : 4:1:1 Bit depth : 8 bits Scan type : Interlaced Scan type, store method : Interleaved fields Scan order : Top Field First Original scan order : Bottom Field First Compression mode : Lossy Bits/(Pixel*Frame) : 2.357 Stream size : 29.1 MiB (59%) Language : English Color primaries : BT.601 NTSC Transfer characteristics : BT.709 Matrix coefficients : BT.601 this moving square with color bars and timecode seems to be good for spotting interlacing ... Other sources, I only looked at few of them, not found anything interlace related: https://www.w6rz.net/

Debian 11
by Sam 17 Nov '20

17 Nov '20

Andrew (or maybe other supporters) do you have the possibility to see which packages are necessary for Debian 11 to install Cinelerra correctly? We currently have this ticket still open. https://www.cinelerra-gg.org/bugtracker/view.php?id=536 Unfortunately I don't know enough about the dependencies. I don't want to bother Phyllis in her grief with it. Maybe we can modify the installation routine to show the right packages for Debian 11. Sam

offtopic: HDMI capture
by Andrew Randrianasulu 17 Nov '20

17 Nov '20

I did little research , and apparently there are some HDMI capture cards/USB 3.0 dongles. But Magewell XI100DUSB-HDMI tend to cost $300 (!!) and while it was reported to work with Linux and standard (in-kernel) UVC driver it only supported 4:2:2 8-bit per component capture .... [video4linux2,v4l2 @ 0x1e46dc0] The v4l2 frame is 0 bytes, but 4147200 bytes are expected. Flags: 0x00002045 Input #0, video4linux2,v4l2, from '/dev/video0': Duration: N/A, bitrate: 995328 kb/s Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 1920x1080, 995328 kb/s, 30 fps, 30 tbr, 1000k tbn, 1000k tbc https://trac.ffmpeg.org/ticket/4030 (this bug was fixed, just showing where I get my info) Unfortunately, there apparently was some another bug in Linux kernel: https://lore.kernel.org/linux-usb/20180515112251.51392d42%40litschi.hi.peng… Not enough bandwidth with Magewell XI100DUSB-HDMI 2018-01-19 20:12 Not sure if it was fixed or not. Declink cards require their own SDK (non-free) On windows it seems to be working ... with some effort: https://ianmorrish.wordpress.com/2019/04/02/ffmpeg-with-decklink-support-fo… there was ffmpeg page showing directshow capture on Windows, this lists some 10-bit formats like [dshow @ 0000007201cda8a0] vcodec=v210 min s=3840x2160 fps=30 max s=3840x2160 fps=30 [dshow @ 0000007201cda8a0] vcodec=r210 min s=1920x1080 fps=23.976 max s=1920x1080 fps=23.976 https://wiki.multimedia.cx/index.php/R210 This codec is used in TV & film production and stores raw 10-bit RGB data. Each red, green, and blue color component is 10 bits wide. https://wiki.multimedia.cx/index.php/V210 The v210 format is a packed YUV 4:2:2 format with 10 bits per component. https://trac.ffmpeg.org/wiki/Capture/Blackmagic But you probably need real ultrafast (NVME?) drive for working with those .... at least at higher resolutions.

small fix for qt vs mov format option
by Andrew Randrianasulu 17 Nov '20

I basically hacked fileffmpeg.C so it will allow me to choose mov flags for (cin-specific) qt 'format'. Of course one can rename all those qt profiles too... int FFOptionsFormatView::handle_event() { Asset *asset = fmt_config->asset; char *format_name = asset->fformat; char *replace_name = "mov"; if (!strcmp(format_name, "qt")) format_name = replace_name; // fixup avformat_free_context(fmt_ctx); fmt_ctx = 0; int ret = avformat_alloc_output_context2(&fmt_ctx, 0, format_name, 0); if( ret || !fmt_ctx ) { eprintf(_("no format named: %s"), format_name); ret = 1; } if( !ret ) fmt_config->start(fmt_ctx); return 1; } basically just three lines.

Missing FHD presets
by Terje J. Hanssen 16 Nov '20

16 Nov '20

The current HDV presets seems to be complete now for native camcorded, mpeg-2 compressed HDV.m2t, 8-bit, 4:2:0 video. At least some HDV camcorders (S. Mullen: HVR-V1 and FX7 Handbook) can output HDV tape playback via HDMI as uncompressed 720p50 or 720p60 (1280x720) chroma upscaled to 4:2:2. Optional shooting live video (without mpeg-2 tape compression) the camera generates uncompressed 1440x1080i with a 4:2:2 colorspace via HDMI. Both these formats can i.e be recorded as in 10-bit ProRes 422 (HQ). Presets? Else it seems the following Full HD presets are missing: Full HD 1920x1080: FHD 1080i /29.97 (available), /25 /50 /24 /60 /30 (missing) FHD 1080p /30 /29.97 /24, /23.976 (available), /25 /50 /60 /30 (missing) Terje J.
