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.

Cinelerra-GG packages build farm
by Андрей Спицын 05 Dec '23

05 Dec '23

Hello Phyllis and everyone, I've created a build farm for cinelerra deb and rpm packages. Although it is at an early stage of development, it can build packages on every git change in the main repo. Feel free to use these packages at https://github.com/einhander/cin-gg-packages/releases. Note that releases correspond to a build date, not a git commit date. Current build hosts are debian 12 and alma linux 8. I'm open to suggestions for a new distro and packages. Best regards, Andrey Spitsyn

cinelerra-gg NetBSD and FreeBSD ports (package rules)
by Andrew Randrianasulu 29 Nov '23

29 Nov '23

so, I spend some more time trying to get packaging on BSD running. I think I have first results, while I probably need more assistance about NetBSD's options/configuration. Upgraded my 9.2 to 9.3, and also packages. some ports do not fit on my small (5 GB) virtual hdd, and netBSD also does not know NFS v4 yet, so my default mount from Slackware failed here. But I used tmp pseudo harddrive attached to netbsd VM like this qemu-system-i386 -hda netbsd-92.qcow -hdb /dev/shm/tmp_1gb_ext2 -enable-kvm -smp 2 -device ES1370 -boot c -netdev user,id=myslirp,ipv6=off -device e1000,netdev=myslirp -m 512 -cpu pentium2 and mounted it inside VM with mount -t ext2fs /dev/wd1 /mnt port for NetBSD specifically does not have OpenEXR support yet, probably I need to add some more includes. ... But basic mpeg2 file playback works.

FreeBSD 14.0 fixes
by Andrew Randrianasulu 27 Nov '23

27 Nov '23

Hopefully they does not break anything else! I run freebsd-update directly from 13.0 to 14.0 and of course was bitten by update bug! :) https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=273661 but now build seems to be ok, next is runtime testing .. PS: 5 Gb is way too small space for modern system, I need to delete few caches, all docs, and even llvm's *.a files :/
