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.

AOM SVT-AV1 2.1 Released
by Terje J. Hanssen 17 Jun '24

17 Jun '24

According to Phoronix the Alliance of Open Media project quietly released (the Intel based) SVT-AV1 v2.1 last week. With this new SVT-AV1 release are yet more performance optimizations and tuning. The M0, M3, M5, and M6 presets are seeing 12~40% speed-ups while maintaining similar quality levels to prior releases. The compression efficiency of presets M11 to M13 meanwhile have improved by 1~2%. New SVT-AV1 benchmarks soon. https://www.phoronix.com/news/SVT-AV1-2.1-Released ---------- Meanwhile, I have updated my previous tests using ffmpeg-7 and libSvtAv1Enc2 version 2.0 on openSUSE Slowroll below. The results are about the same speed +/- compared as my earlier tests using ffmpeg-6 and SVT-AV1 encoder version 1.7 https://lists.cinelerra-gg.org/pipermail/cin/2023-December/007436.html (Else I have purchased the hardware components to upgrade and rebuild my workstations for a planned AV1 QSV/hw video transcoding: mobo, Intel cpu and gpu, memory, ssd, cooler. More about this later. But first I have to finish my ongoing DVD Video project).

ChromakeyHSV menu much improved
by Phyllis Smith 11 Jun '24

11 Jun '24

Checked into GIT an anonymous contribution for a much improved ChromakeyHSV menu to include: 1) Now there are individual boxes on the left side where you can either keyin a distinct value or use the up/down arrows to change the value. This gives you a much better control than where previously you could only move the slider to jiggle the number you wanted. Also, much easier to see what all the values are at once whereas before you had to click on each individual diamond setting to see just 1 value. 2) You can reset individual parameters to the default. Before you could only reset them all so you would lose a particular value you were already happy with. 3) The menu is more visible over a larger space making it easier to see. 4) Plus some minor code cleanup to eliminate at least 1 duplicate line and to put some "int" on same lines as statement. P.S. Someone indicated that ChromakeyHSV had some kind of bug, but I was wondering if Andrea ever found out exactly what that was? since it looks OK to me.

A potential HTML manual problem under NTFS/FAT filesystems
by Georgy Salnikov 31 May '24

31 May '24

I accidentally found, that in the huge list of files produced by latex2html from the CGG manual there are HTML pages, whose filenames differ from each others in the letter case only. This is no problem under Linux. But if somebody copies all the files to a Windows computer (with an NTFS-like filesystem), or to a memory stick formatted as FAT32, or to some network (Windows or Samba) disk where differences between upper/lower case in filenames are ignored by the operating system, then some HTML pages will be overwritten by others and disappear. I have found 4 such potentially conflicting pairs of page names: Compositor_Window.html - describes the whole Compositor GUI (Chapter 2) Compositor_window.html - describes the Compositor shortcuts (Chapter 15) Viewer_Window.html - describes the whole Viewer GUI (Chapter 2) Viewer_window.html - describes the Viewer shortcuts (Chapter 15) Final_note.html - about copy/paste text highlighting in Chapter 17 (How some stuff works) Final_Note.html - a link to wiki.archlinux.org on hardware video acceleration from Chapter 19 (Performance and other tips) Index.html - the Index at the very end of the manual index.html - the default start page, automatically created by latex2html as the exact copy of (hard link to) CinelerraGG_Manual.html The automatic creation of index.html can be suppressed by the latex2html option -noauto_link, and this file is not used by CGG Context Help (while Index.html is used). If renaming other sections (for example "Compositor window" to "Compositor window shortcuts" or "Final Note" to "Further topics on hardware acceleration", or something like this) is desirable, to me is open question.

OT: video about old usb 1.1 capture device
by Andrew Randrianasulu 23 May '24

23 May '24

Under old windows, too .. but as top comment says, quality is quite surprizing, considering all limitations. https://m.youtube.com/watch?v=4U32Hl4uSBs "USB video capture in 2002: Dazzle DCS 200" mpeg2 SD video (NTSC/PAL), at around 6 Mbits/s ofcourse capturing raw/lossless is superior ... if you have hd space. But I guess analog/noise filtering part in those old parts was main feature and not afterthought like on some more modern devices {echoing from comments}
