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.

Re: [Cin] cinelerra-gg on ppc64el
by Daniel Reurich 02 Apr '22

02 Apr '22

Hi I've made some significant progress in getting the build going - and will have some patches to drop that solve some issues for builds using system libs and non x86 based archs. The current issue I'm stumbling on is that configure doesn't detect the systems liba52 and a52dec/a52.h header files as installed. This results in a linking failure during the build of libzmpeg Any thoughts on how I might overcome that? Thanks, Daniel. -- Daniel Reurich Centurion Computer Technology (2005) Ltd. 021 797 722

Cinelerra context help - a complete implementation
by Georgy Salnikov 24 Mar '22

24 Mar '22

Hi all, This new implementation of Cinelerra context help can be requested from almost any Cinelerra window or subwindow by pointing with the mouse cursor on the GUI element of interest and pressing Alt/h. That HTML manual page will be shown via the configured web browser, which is assumed as most relevant to the GUI element being currently under the mouse pointer. For more information see issue 568 on the bugtracker: https://www.cinelerra-gg.org/bugtracker/view.php?id=568 How to install, configure and demonstrate the new functionality --------------------------------------------------------------- 1. Apply the patch (see BT568) to the CinGG source tree: https://www.cinelerra-gg.org/bugtracker/file_download.php?file_id=775&type=… 2. After patching one new file appears: doc/ContextManual.pl. This is a perl script. It must be given exetutable permissions. 3. Build and install CinGG as usual. 4. The prerequisite for context help is CinelerraGG HTML manual. After installation of CinGG itself, place the complete unchanged directory CinelerraGG_Manual, as it was produced by latex2html from the manual package, into the 'doc' directory of the installed Cinelerra package. This will be the directory bin/doc/CinelerraGG_Manual if CinGG was built --with-single-user. The script ContextManual.pl should appear after installation also here, in bin/doc. 5. In principle, this is sufficient. Nevertheless, the bin/doc/ContextManual.pl script can be configured further. Look in the script text. You can define your preferable web browser, or redefine it to 'echo' for debug purposes. There are also some predefined HTML pages for Contents and Index, and several explicitly rewritten keyphrases. However, there can be hardly a need to redefine anything except the name of the browser executable. 6. Start Cinelerra and open a project with some assets, effects, keyframes, etc. May be, open some additional Cinelerra dialog windows, plugin settings, etc. Try to point with the mouse on different GUI elements or on empty spaces in different windows and press Alt/h. You should get different manual pages in the browser (if browser was not yet started, it should start automatically). How it works, from the user's point of view ------------------------------------------- The hotkey to request context help is Alt/h. Why? A simple 'h' does not fit: in text fields it has to input the letter 'h'. So is Shift/h: it would mean the capital letter 'H'. Ctrl/h and Ctrl/Shift/h are also not suitable: it is <Backspace>. Something like <F1> would be also not good, <Fn> are already utilized in Compositor. Unlike these all, Alt/h seems to be a good hotkey and, to the best of my knowledge, it is not assigned to anything else throughout the whole Cinelerra code. What particular help page is shown, depends on the mouse cursor location while Alt/h is pressed. Usually, when the mouse is located in some window or dialog, the help page related to the functionality of this window or dialog is shown. In this case the mouse can point either on some widget, or on an empty area in the window. In Cinelerra GUI there are several rich loaded windows, Timeline and Compositor for example. In such a case different help pages can be requested depending on the particular GUI element under the mouse. For example, pressing Alt/h while pointing on the Autos curve in a track would show help on automation keyframes, pointing on the Overlay mode button in the patchbay would show help on overlays, pointing on the camera control in Compositor would show help on camera and projector. If no context dependent help page is found, the manual page of Contents itself is shown. Most probably it means, that either the meaning of this window is obvious (so is the 'Tip of the day' window, for example), or it is not (yet) documented. Requesting context help for plugins ----------------------------------- There are following possibilities to request help page for the particular plugin of interest. 1) Pressing Alt/h with mouse in the dialog window of plugin settings 2) Pressing Alt/h while pointing with the mouse on the plugin bar in a track (or transition bar, or transition icon) 3) Pressing Alt/h while pointing on the plugin name (icon) in the Resources window. If plugin tooltips are on, help for the highlighted (plugin under mouse) is shown. If plugin tooltips are off, help for the selected plugin is shown (it is made so, because in the latter case it would be difficult to figure out, without a visual feedback, which particular item is currently under mouse). 4) Pressing Alt/h while pointing on the plugin name in the Attach Effect dialog Requesting context help on Contour Shuttle ------------------------------------------ Contour Shuttle has no Alt/h, yeh. Nevertheless, its help page can be requested by simultaneous pressing both Alt keys (left and right) on the keyboard followed by pressing any button on the Contour Shuttle. Here, pressing both Alt keys is necessary due to the way of X11 to track the status of modifiers. To cancel this mode, press any single modifier key (Alt, Ctrl or Shift) once. _______________________________________________________________________________ Georgy Salnikov NMR Group Novosibirsk Institute of Organic Chemistry Lavrentjeva, 9, 630090 Novosibirsk, Russia Phone +7-383-3307864 Email sge(a)nmr.nioch.nsc.ru _______________________________________________________________________________

Fwd: Webpage Translation into Spanish
by Rafa Mar Multimedia en Gnu\Linux 28 Jan '22

28 Jan '22

Hi dear Phyllis Spanish translation of the terms of the appearance tab of the configuration: Autosave continous backups = *Copia de seguridad continua* The tip in Spanish = *Cuando cierre Cinelerra se guardarán unicamente las últimas 50 copias de seguridad. Si trabaja durante mucho tiempo sin reiniciar Cinelerra, corre el riesgo de ocupar mucho espacio con las continuas copias de seguridad.* Greetings!!

The October 31, 2021 CinGG releases are at: https://cinelerra-gg.org/download/images/CinGG-20211031-x86_64.AppImage https://cinelerra-gg.org/download/images/CinGG-20211031-x86_64-older_distro… https://cinelerra-gg.org/download/images/CinGG-20211031-multibit.AppImage https://cinelerra-gg.org/download/images/CinGG-20211031-i386.AppImage *GIT for Cinelerra-GG has the following changes from 10/01/2021-10/31/2021* The instructions for using AppImage in the file, *README_appimage.txt*, was updated by *Terje*. *Cineform, DPX, MXF *additional render formats have been provided as used in ffmpeg by *Andrea*. *Title video plugin* now correctly fades in/out as reported by *Camille.* This bug had been around a very long time (see BT #559) with the fix now done by a Freelancer. Many *plugins were being reloaded* in the AppImage on every start which could take awhile on some computers. *MatN* has expertly fixed this and changed that of the Cinelerra_plugins also. Note that any time a new release/build is started for the first time, it will always reload the plugins but each subsequent usage of that image will no longer require reloads as long as you use the same .bcast5. *Andrew-R contributions:* Opus and aom thirdparty libraries have had the examples and extras deleted to save build time. *In support of Android/Termux* CinGG compile, patches for libwepb and libaom have been added. Defaults for mxf render format have now been established. *Hungarian translation* as created using google with a 90% automated procedure is now available. To use, keyin the following in a window: LANGUAGE=hu ./CinGG-20211031-x86_64.AppImage

libaom 3.2.0
by Andrew Randrianasulu 01 Nov '21

01 Nov '21

https://aomedia.googlesource.com/aom/+/refs/tags/v3.2.0/CHANGELOG --- This release includes compression efficiency and perceptual quality improvements, speedup and memory optimizations, as well as some new features. - New Features * Introduced speeds 7, 8, and 9 for all intra mode. * Introduced speed 10 for real time mode. * Introduced an API that allows external partition decisions. * SVC: added support for compound prediction. * SVC: added support for fixed SVC modes. - Compression Efficiency Improvements * Intra-mode search improvement. * Improved real time (RT) mode BDrate savings by ~5% (RT speed 5) and ~12% (RT speed 6). The improvement was measured on the video conference set. * Improved real time mode for nonrd path (speed 7, 8, 9): BDrate gains of ~3-5%. * Rate control and RD adjustments based on ML research in VP9. Gains of ~0.5-1.0% for HD. - Perceptual Quality Improvements * Added a new mode --deltaq-mode=3 to improve perceptual quality based on a differential contrast model for still images. * Added a new mode –deltaq-mode=4 to improve perceptual quality based on user rated cq_level data set for still images. * Weighting of some intra mode and partition size choices to better manage and retain texture. - Speedup and Memory Optimizations * Further improved 2-pass good quality encoder speed: o Speed 2 speedup: 18% o Speed 3 speedup: 22% o Speed 4 speedup: 37% o Speed 5 speedup: 30% o Speed 6 speedup: 20% * Optimized the real time encoder (measured on the video conference set): o RT speed 5 speedup: 110% o RT speed 6 speedup: 77% - Bug Fixes * Issue 3069: Fix one-pass mode keyframe placement off-by-one error. * Issue 3156: Fix a bug in av1_quantize_lp AVX2 optimization. --- I quickly re-packed .tar.gz into xz and renamed libaom patches accordingly. It seems to work with ffmpeg-4.4. Phyllis, can you test (may be next month?) if libaom-3.2.0 still works on both new and old distros (as you use them for appimage build)? Also, ffmpeg 4.4.1 was released - mostly bugfixes from fuzzers, it seems, but also few changes in util https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/7e0d640edf6c3eee1816b105c2f74… https://git.ffmpeg.org/gitweb/ffmpeg.git/tag/2aa4f5cc8be5e3168191cd13a61178…

I thought about implementing the various DNxHRs in the mxf format, which is their natural format (Andrew had already started with the proxy). Those already present as mov can be left or removed; I would leave them.
