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 26 Aug '24

26 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.

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.

Fwd: [cinelerra-cv-team] About copy-pasting from CV Manual to CGG Manual
by Andrea paz 01 May '24

01 May '24

---------- Forwarded message --------- Da: Igor Vladimirsky <sitelve(a)gmail.com> Date: mar 30 apr 2024 alle ore 20:20 Subject: [cinelerra-cv-team] About copy-pasting from CV Manual to CGG Manual To: <cinelerra-cv-team(a)freelists.org> Each of my messages to the Cin-GG ML is moderated. This is why I have opened this thread here and restoring the chronology --------------- 28.04.2023 Andrea Paz wrote the msg to the CinGG ML. https://lists.cinelerra-gg.org/pipermail/cin/2024-April/008211.html Quote: I have updated the plugins chapter, based on IgorV's updates for the manual of Cinelerra-CV. (See: https://github.com/cinelerra-cv-team/cinelerra-cv/commits/master/doc) Check that they fit. -------------------- My answer to the CinGG ML was: ------------> Do marketers of the Cin-GG Community discourage linking to sources? I want to remind them of something. The CV manual was mostly copied (many years ago) from the HV-manual & the Alex's cv-wiki. The content of the CGG manual was mostly copied from HV/CV-manuals and Features5.1 and paraphrased (in some places)/reordered for pseudo-originality & better understanding/usability (however, you did not solve the problems of the previous manuals). + you described well the new functions made by William Morrow aka GoodGuy (but not all as far as I remember). The content was copied from hv-cv_mans to cgg-man without providing links to hv-cv_sources and contributors. The CGG-manual contains only this: Information contained in this manual is a description of the CINELERRA-GG program usage and was obtained from various sources to include different communication channels, emails, common knowledge, and write-ups as new features were added In CV: This manual originates from "Secrets of Cinelerra", an excellent primer written by Adam WILLIAMS from HEROINE VIRTUAL LTD. In 2003 Alex FERRER created a Wiki based on that manual and added many screenshots and topic descriptions. The CV-manual contains a list of its contributors. So, - I provided a description of how chromakey-hsv works not for the CGG-manual, but for the CV-manual. Therefore you have to indicate the source. - Marketers of your community should finally make an effort on themselves and indicate the main sources of origin of the contents of the CinGG-manual. Good luck. ---------------------------------------------------------------- ---------------------------------------- As expected, the msg above did not pass moderation in the GG-ML and was banned. However, I see some progressive changes here https://git.cinelerra-gg.org/git/?p=goodguy/cin-manual-latex.git;a=shortlog BTW, The traditional tendency (in CinGG) to not indicate sources of origin and assign the original name of the program to the fork was evident many years ago. --------------------- 30.04.2023 Andrea Paz wrote the msg to the CinGG ML. https://lists.cinelerra-gg.org/pipermail/cin/2024-April/008221.html QUOTE: @igor_ubuntu (Igor Vladimirsky) See if the changes made to the manual sound good to you. https://git.cinelerra-gg.org/git/?p=goodguy/cin-manual-latex.git;a=commitdi… If that doesn't work for you, try writing something yourself (plain text is fine) and then put it here in the thread so it can be integrated into the manual. If, on the other hand, what you are asking for is that every sentenceI take from your manual report the author, then I apologize for what I have done so far. I thought that having asked your permission and then mentioning you on the mailing list (complete with a link) was enough. From now on, I will not resume sentences written by others to avoid these problems. -------------------------- --------------------------------- My answer (here, in the freelist): Andrea Paz, you know that my messages are moderated. Therefore, your proposal to write something to the gg-ml sounds like a mockery. If you carefully read the original of my message, you can see that there is no requirement in it quote:"that every sentence I take from your manual report the author". I talk about chromakey and about indicating the main sources of origin of your manual.. However, for the future: Texts written by me for my blog/yt-channel and transferred to the cv manual 1 - may only be copied to cgg-man with my permission. 2 - you may copy them only after indicating that this text was written by .. and was copied by you from cv-man to gg-man 3 - the copied text must have a direct link (to the original) in the text, and not somewhere at the bottom of the page. I have no desire to improve (neither directly nor indirectly) cgg-manual and I do not want to be an anonymous hero. I don't really hate cgg, but marketing I just can't stand. You can, of course, copy other text from cv-man without any conditions (it is under GPL). We all use open sources, in particular the mailing list archive. Phyllis finally indicated the sources of the cgg manual. It's enough. Until today, I have not taken the text from your manual. But if you copy/paste texts for cv-man, then don’t be surprised if I will copy/paste texts from the cgg-man. However, I have no plans to do this. ---------- Now, Andrea, please, take the link to this message and send it to the GG ML. So that we don't "play with a damaged phone". IgorV

OT: when you try to record dolphin, but result is mostly radio interference
by Andrew Randrianasulu 30 Apr '24

30 Apr '24

My long-time friend Julian trying to record some underwater acoustics with resident dolphin known as Randy. Well, long chain of equipment (hydrophone, pream, macbook with some adapters because apple eliminated normal separate audio line in/outs) resulted in this: https://drive.google.com/drive/folders/1Mm_Gt8XneZI5fFAgJcy4lE6G5vNcALlI?us… For some reason Audacity for mac refused to record above 44.1 Khz sampling rate, so all sound still limited to around 22 Khz frequencies. I suggested Ubuntu studio 24.04 but while personally testing my suggestion I run into problems, spend some time resetting win 8.1 on laptop (there was magical command to make Windows boot again but you need Windows install image for it to work ...)

HTML manual
by Andrea paz 27 Apr '24

27 Apr '24

Trying to open the html manual directly from the website, I no longer get to the cover and context menu, but I get to our repository list files. See video: https://streamable.com/o4dryf This has been happening for a couple of weeks. I don't know if it's my fault and the endless ad-blockers I use in my Firefox...
