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.

Weird world of WINDOW_CONFIG!
by Andrew Randrianasulu 02 Jun '23

02 Jun '23

so, I looked in mainsession.C while hunting about a_x11_host callsites see what I found: void MainSession::default_window_positions(int window_config) { // 0 - all windows on a, playback_config a // 1 - all windows on b, playback_config b // 2 - all windows on a, except composer on b, playback_config b but in reality this config set everything on A (Xephyr screen) A_X11_HOST :1.0 B_X11_HOST :0.0 WINDOW_CONFIG 2 this config set everything BUT compositor on A A_X11_HOST :1.0 B_X11_HOST :0.0 WINDOW_CONFIG 1 this config set only compositor on B: A_X11_HOST :0.0 B_X11_HOST :1.0 WINDOW_CONFIG 1 and this config se ALL on A A_X11_HOST :0.0 B_X11_HOST :1.0 WINDOW_CONFIG 0 so check your Cinelerra_rc for WINDOW_CONFIG value!

March 2023 release - still gmail bounces
by Phyllis Smith 31 Mar '23

31 Mar '23

New March AppImage releases at: https://cinelerra-gg.org/download/images/and updated releasenotes.pdf, CinelerraGG_Manual.pdf, and manual HTML files (CinelerraGG_Manual)) at: https://cinelerra-gg.org/download/ GIT for Cinelerra-GG has the following changes from 03/01/2023-03/31/2023 Noexecstack to loader added as Rob pointed out as an issue and with patch provided by Andrew. Shuttle code now has duplication for shuttle devices as if00 in addition to the original mouse as discovered by Stefan who found the problem and supplied the solution. Updated libraries include the following: Flac to1.4.2 from 1.4.0 Libjpeg-Turbo to 2.1.5.1 from 2.1.2 Libvpx to 1.13.0 from 1.12.0 Tiff to 4.5.0 from 4.4.0 Mailing List problem for users with gmail accounts continues to be an issue that may remain unsolved for some time. Google has not responded to Case ID 8-1804000033973 logged by Phyllis and there is no longer any expectation that they will. The problem is that Google is now treating the email to gmail users to be “possibly unsolicited” even though it has been in use and stable for a limited number of users for 2 ½ years. To monitor the Mailing List, just view the latest at: https://www.mail-archive.com/[email protected]/maillist.htmland now I am not sure if gmail users can even send mail to go through.

Cinellera360: the ultimate free VR editor
by Stefan de Konink 29 Mar '23

29 Mar '23

You got my clickbait? I got your attention. Nothing on the internet mentions that Cinelerra is capable of editing 360 video's, but it certainly is: with the help of ffmpeg's F_v360 plugin. Either creating the 360 content, or extracting it in a regular video. So as you all already expected from my I was doing stuff with Cinelerra-gg that likely nobody did before and noticed some particularities that I really did not understand. My steps: 1. My project settings remain 1920x1080. 2. Just grab any equirectangular video bigger than your project size. The one I got my hands on was 4096x2048. In my project I want to use a part of this video as illustration of the user experience. This would mean I need to project the equirectangular projection into a flat projection. 3. For the plugin settings that would be input=0 and output=4. What I noticed when I modulated the yaw was that I would never see the entire view, then when rotating the back of the video would 'clip' at -180 degrees. 4. When changing the camera to Z = 0.469 (1920/4096) I was able to get a 360 degree rotatable camera. 5. Setting up d_fov = 120, the image would be closely mimicking the experience. Now what Cinelerra bring you from this point. Keyframing a property of the plugin, and there it becomes interesting. Plugin keyframes seem to give the control what we are looking for here. I can set the yaw using "Generate keyframes while tweeking", but what I would be actually looking for is the same set of curves that would be available when changing x,y,z,opacity etc. How would I get interpolation working? Could anyone elaborate how Cinelerra knows it can interpolate some of the parameters, but not others? And personally I think what is more fundamentally lacking in Cinelerra: a timeline view analogue to Blender where any property can be placed in view: where I would suggest to normalise the min and max to sensible properties opposed to the current: stack everything on the track and break your project by an unintended mouse click. -- Stefan
