FranceBB's LUT collection
by Andrew Randrianasulu 16 May '25

16 May '25

forum https://forum.doom9.org/showthread.php?t=176091 it says those LUTs should be usable for ffmpeg's lut3d and therefore for CinGG? github (each *.cube can be several mb's big) https://github.com/FranceBB/LinearTransformation author says they were verified on professional equipment... list includes PAL and NTSC variants for rec. 601....

I tried to add AVC-Intra 100 output profiles
by Andrew Randrianasulu 08 May '25

08 May '25

But not sure if I did this correctly. https://en.wikipedia.org/wiki/AVC-Intra says for AVC-Intra 100: AVC-Intra 100: nominally 100 Mbit/s, size of each frame is fixed CAVLC entropy coding only. All formats are High 4:2:2 Intra Profile, Level 4.1 4:2:2 chrominance sampling frames are not scaled and yeah, this French-language pdf actually says the same: https://web.archive.org/web/20110720215759/http://www.ficam.fr/upload/docum… 50M 100M Standard MPEG-4 part10 AVC/H.264 Profile High 10 Intra High 4:2:2 Intra Level Level 3.2/4.0 Level 4.1 Resolution 1440x1080 / 960x720 1920x1080 / 1280x720 Sampling 4:2:0 4:2:2 Bit rate 54Mbps 111Mbps Block size Y: 8x8, C: 4x4 Intra Prediction Y: 9mode, C: 4mode MBAFF Yes De-block filter No Slice/frame 10 Entropy coding CABAC CAVLC so, I looked up ffmpeg cmd line https://trac.ffmpeg.org/ticket/3597 ffmpeg -v info -i /mnt-data/backup4/vol0/export/CUHK\ 2014-1/V017b.mov -vcodec libx264 -intra -pix_fmt yuv422p10le -vb 100M -x264opts avcintra-class=100 -x264opts colorprim=bt709 -x264opts transfer=bt709 -x264opts colormatrix=bt709 -threads 4 -acodec copy V017b-ffmpeg-git-avcintra100.mov Huh, said I and entered those params in opts file, actually in two files (mp4 and mov containers) mov libx264 cin_pix_fmt=yuv422p10le flags -global_header keyint_min=0 x264-params=keyint=0:colorprim=bt709:transfer=bt709:colormatrix=bt709 avcintra-class=100 bufsize=100000000 level=4.1 mp4 libx264 cin_pix_fmt=yuv422p10le flags -global_header keyint_min=0 x264-params=keyint=0:colorprim=bt709:transfer=bt709:colormatrix=bt709 avcintra-class=100 bufsize=100000000 level=4.1 both for progressive content, for interlace you must add some more flags: https://lists.ffmpeg.org/pipermail/ffmpeg-user/2017-January/035049.html -flags +ildct+ilme -x264opts interlaced=1 Also, there is still lack of (GUI) user notification if file writing failed due to NO SPACE on device :} FFStream::write_packet: write packet failed. file:/dev/shm/avci_new.mp4 err: На устройстве не осталось свободного места FFStream::encode_frame: encode failed. file: /dev/shm/avci_new.mp4 err: На устройстве не осталось свободного места FFStream::flush failed :file:/dev/shm/avci_new.mp4 err: Операция не позволена Render::render_single: Session finished. ** rendered 273 frames in 85.585 secs, 3.190 fps Render::render_single: Session finished. ** rendered 273 frames in 85.485 secs, 3.194 fps Render::render_single: Session finished. ** rendered 273 frames in 82.176 secs, 3.322 fps Profile sort of assumes you set project to some supported resolution, framerate, etc, otherwise libx264 will fail with console error message..... I found some talk about AVC-Ultra, there even was patch for x264, but it was not merged: https://mailman.videolan.org/pipermail/x264-devel/2015-September/011412.html Also, I think sound must be uncompressed, but I'm not sure.

offtopic: Quantel boxes
by Andrew Randrianasulu 25 Aug '24

25 Aug '24

Because I monitor mame WIP thread I saw some news about Quantel Paintbox emulation in MAME (0) and then I randomly followed some links to other Quantel systems Like HAL (basically like hardware compositor) http://dexterslab2013.blogspot.com/2018/03/quantel-hal-video-compositing-sy… 99 layers of SD images or video, up to 15 min storage on 20 disk array! https://m.youtube.com/watch?v=4k15hpeGzBA if you have half of hour you can watch this demo from 1997. Biggest thing so far for me? We are free to use old-fashioned optical effects in front of real camera too :) (0) - https://forums.bannister.org/ubbthreads.php?ubb=showflat&Number=120292&page…

New release update
by Phyllis Smith 19 Jul '24

19 Jul '24

October 2022 end of month new release AppImages now available. This includes a fix for a minor ffmpeg 5.1 security flaw that Andrew discovered and made us a patch for. Full release notes at: https://cinelerra-gg.org/download/releasenotes.pdf . ************ October Release Notes update ****************** *Security flaw in FFmpeg 5.1* was discovered and Andrew forwarded the patch for us to use. A *Direct Copy speed-up* has been added for EXR and PPM sequences that Andrew found. Tiny corrections and addition to Cinelerra_factory presets and plugin.opts. Newer versions of Ubuntu require an additional package install for *bld_prepare.sh as Goat found*. The Manual has had another section added, *Alternative Views of Overlay Modes*, which presents a more “real world” usage display of the overlay modes using a color/black & white gradient + video.

Weird world of WINDOW_CONFIG!
by Andrew Randrianasulu 02 Jun '23

02 Jun '23

so, I looked in mainsession.C while hunting about a_x11_host callsites see what I found: void MainSession::default_window_positions(int window_config) { // 0 - all windows on a, playback_config a // 1 - all windows on b, playback_config b // 2 - all windows on a, except composer on b, playback_config b but in reality this config set everything on A (Xephyr screen) A_X11_HOST :1.0 B_X11_HOST :0.0 WINDOW_CONFIG 2 this config set everything BUT compositor on A A_X11_HOST :1.0 B_X11_HOST :0.0 WINDOW_CONFIG 1 this config set only compositor on B: A_X11_HOST :0.0 B_X11_HOST :1.0 WINDOW_CONFIG 1 and this config se ALL on A A_X11_HOST :0.0 B_X11_HOST :1.0 WINDOW_CONFIG 0 so check your Cinelerra_rc for WINDOW_CONFIG value!

ms2130 HDMI-USB3 UHD capture card - not quite as expected?
by Terje J. Hanssen 09 Mar '23

09 Mar '23

So I have received the ms2130 HDMI-USB3 capture card. The A/D AV converter & SV-HDMI/adapter is not received so far, and I have not avialable my HDV camcorder (on service) to output HDMI video stream with. Yet, I have initially run some verification tests on the ms2130 HDMI-USB3 UHD capture card alone, for what they are worth. As "UHD" (and/or USB3) is mostly generic used to identify this card (while ms2130 almost not), the some output is piped and stripped with grep "UHD". ---------------- dmesg | grep UHD [ 2.798210] usb 2-5: Product: USB3.0 UHD [ 2.827772] hid-generic 0003:345F:2130.0005: hiddev97,hidraw4: USB HID v1.10 Device [MACROSILICON USB3.0 UHD] on usb-0000:00:14.0-5/input4 [ 4.805554] usb 2-5: Found UVC 1.00 device USB3.0 UHD (345f:2130) udevadm info /dev/video* | egrep 'DEVNAME|ID_V4L_PRODUCT' E: DEVNAME=/dev/video0 E: ID_V4L_PRODUCT=USB 2.0 Camera: HD 720P Webcam E: DEVNAME=/dev/video1 E: ID_V4L_PRODUCT=USB 2.0 Camera: HD 720P Webcam E: DEVNAME=/dev/video2 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD E: DEVNAME=/dev/video3 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD udevadm info /dev/video* | egrep UHD S: v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index0 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD E: ID_MODEL=USB3.0_UHD E: ID_MODEL_ENC=USB3.0\x20UHD E: ID_SERIAL=MACROSILICON_USB3.0_UHD_20210623 E: DEVLINKS=/dev/v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index0 /dev/v4l/by-path/pci-0000:00:14.0-usb-0:5:1.0-video-index0 S: v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index1 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD E: ID_MODEL=USB3.0_UHD E: ID_MODEL_ENC=USB3.0\x20UHD E: ID_SERIAL=MACROSILICON_USB3.0_UHD_20210623 E: DEVLINKS=/dev/v4l/by-path/pci-0000:00:14.0-usb-0:5:1.0-video-index1 /dev/v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index1 lsusb | grep UHD Bus 002 Device 004: ID 345f:2130 MACROSILICON USB3.0 UHD cat /proc/asound/cards | grep UHD 2 [UHD ]: USB-Audio - USB3.0 UHD MACROSILICON USB3.0 UHD at usb-0000:00:14.0-5, super speed ll /dev/video* crw-rw----+ 1 root video 81, 0 feb. 25 14:15 /dev/video0 crw-rw----+ 1 root video 81, 1 feb. 25 14:15 /dev/video1 crw-rw----+ 1 root video 81, 2 feb. 25 14:15 /dev/video2 crw-rw----+ 1 root video 81, 3 feb. 25 14:15 /dev/video3 --------------------- v4l2-ctl --list-devices USB 2.0 Camera: HD 720P Webcam (usb-0000:00:14.0-11): /dev/video0 /dev/video1 USB3.0 UHD: USB3.0 UHD (usb-0000:00:14.0-5): /dev/video2 /dev/video3 ----------- v4l2-ctl --list-formats-ext ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUYV 4:2:2 Size: Discrete 640x480 Interval: Discrete 0.030s (33.000 fps) Interval: Discrete 0.067s (15.000 fps) Size: Discrete 1280x720 Interval: Discrete 0.100s (10.000 fps) Size: Discrete 640x360 Interval: Discrete 0.030s (33.000 fps) Interval: Discrete 0.067s (15.000 fps) ................
