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!!

exportEDL, timecode patches
by Andrew Randrianasulu 17 Jul '21

17 Jul '21

I think I enabled _writing_ timecode info into rendered files (tested mxf) if you set timecode for your timeline manually - it should be respected. If you render selection of your timeline - timecode will be set at start timecode of your render position. if you render selection with already altered (via clapping icon) timeline - it also should work. I found you (sometimes?) need to hit 'align timecodes' menu item for refreshing asset timecode info.... but such action will mes up timeline if some assets had no real timecode info.... Anyway, try to test those patches and told us how useful (or dangerous?) they are... In theory I think this is good idea to get embedded timecodes into rendered files (rel. to your working timeline) , but may be you sometimes want zeroed tc in output files?

New AppImages available dated June 30, 2021
by Phyllis Smith 30 Jun '21

30 Jun '21

In the Download area under images, are the newest AppImages including, for the first time, a 32-bit version: CinGG-20210630-i386.AppImage -- 32-bit version built on Debian 9.1 (so not really that old of a distro) CinGG-20210630-x86_64-older_distros.AppImage -- built on ubuntu 16 CinGG-20210630-x86_64.AppImage -- built on Fedora 32 Updated PDF and HTML versions of manual. Added Tag to both source and manual GITs. Put html tgz manual in images subdirectory so it matches for self-builders to add fo Alt/h hotkey in bin/doc. Release notes updated. ************** Release Notes Summary *********** Additional choices for high FPS rendering Settings→Format have been added by Andrew for Video and Audio. This mod fixes the problem reported by Gorge where it was not possible to render at a format over 60fps. A speed improvement using av1.webm when rendering was implemented by Andrew. This makes it now possible to use this as it is 7 times faster on at least 1 typical multi-cpu laptop. Gang Channels and Gang Media was not correctly handling disarmed tracks as reported by Scossu in the forum and BT #577. IgorBeg tested a fix by commenting out the relevant code. Additional mxf container render formats added by Andrew to include 6 new video + 2 audio. Other new render formats include: h263.mov, h263p.mov, and improved cinepak.qt speed. An OBS Studio user, Sparkill, has contributed a render format for creating a youtube based on video recorded in OBS with Color Format: I444 (yuv444p), Color Space: 709, Color range: Full (JPEG) called “obs2youtube.mp4” in the render format Video and Audio wrenches. Upgrade of third party library: libjpeg-turbo from 2.0.5 to 2.1.0 via Andrew.

new overlay mode from Freelancer
by Andrew Randrianasulu 29 Jun '21

29 Jun '21

finally looked at history.. http://git.cinelerra-gg.org/git/?p=goodguy/history.git;a=blobdiff;f=cineler… and made this patch (attached) it works softer than logical or porter/duff modes, but notiecably slower ( (on 8 core arm tablet) my modes fails to compile - something about me not really knowing how to write macro functions (?)

possible cinepack profile speedup
by Andrew Randrianasulu 29 Jun '21

29 Jun '21

I basically added max_extra_cb_iterations=0 min_strips=3 this speedups encoder but quality is lower (not sure how much, was too inpatient to wait for 1 min clip encode at 352*144 25 fps! with those parameters ffmpeg encodes at nearly 3 fps, yay! In theory one can try to set up renderfarm + number parallel ffmpeg encoders, because encoder is single threaded - but I haven't tested this) also added two old (1996/8) h263 codecs - it theory they should be good for low-cpu decoding (on emulated computers for example), but apparently h263 without 'p' only good at few pre-defined resolutions? there is also speedhq.qt - for ffmpeg 4.4 (sadly ffmpeg can't encode video with alpha, as this mpeg2-like format supports...) sorry for not making progress on more important issues - I fiddled around with overlayframe.h - but I can't see my addons working? Either bug in code or I translated those blend modes wrongly.. there also two ffmpeg-4.4 patches recently added to git - they apply with patch -p1 yet not with git apply patch (misformatted patch).. Adds avc intra 300/480 if compiled against last x264 (15 june 2021)
