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.

Monthly AppImage updates
by Phyllis Smith 05 Sep '23

05 Sep '23

April 30th AppImages are now available with the binary only updated with X264 r3106 stable mods. But, I have a problem with being able to update the GIT repository on the server due to some error I made which I am now working on. Release Notes Update below: *********************************** GIT for Cinelerra-GG has the following changes from 04/01/2023-04/30/2023 *Server Maintenance work has been done by Sam* on an ongoing basis along with the difficult task of accommodating newer requirements by Google Gmail. Changes to the Mailing List settings for compliance was very time-consuming and much appreciation goes to Sam for continuing to volunteer his time for critical needs. *X264 *has been upgraded to r3106 stable release. There appears to be no X265 stable updates. *Clang-16* related modifications in thirdparty/Makefile, libuuid-1.0.3, and mpeg2enc.c to support new termux distro have been contributed by *Andrew*. *Prores_ks *render format has had the Apple writing library added as the default with ffmpeg since that is who created this specific prores format. This should make the rendered video more compatible with other software products. Mod provided by *Andrea*.

Weekend fun
by Andrew Randrianasulu 25 Jun '23

25 Jun '23

https://cloud.mail.ru/public/gJ3D/JJmkHFCC6 should contain same vid as https://youtu.be/ouE6UABWXRE but less mangled (60 mb for 3 minutes) Captured with cingg on my poor integrated "GPU". (first to magicyuv to tmpfs - 4.6 Gb! then encoded to yuv444 h264. Not even sure if I set full/limited range correctly .. watch via mplayer -vo gl) Main thing I did here is manual setting of cpu cores for cingg/capture (0 and 1) and ssh (#3). You can (hopefully) see how my desktop machine render OpenGL 1.4 via wireless link from laptop under keyboard. Both systems running slightly de-synchronized Slackware i586 with 64-bit kernels. Second X server because I was too lazy for restarting my main one :)

In the youtube channel there is a request if it is possible to dynamically alter subtitles. I think not, but can anyone answer precisely? https://www.youtube.com/watch?v=JPhO2sscZzU&list=PLOnHGAy9DoU0dBhf7ibgsmpdd…
