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.

Varied Standard Shortcuts AppImage version for testing
by Phyllis Smith 13 Oct '23

13 Oct '23

There is a modified Shortcuts AppImage version for testing on 64-bit O/S which is set up to be more in sync with what is considered to be "Standard" shortcuts for NLEs.. IgorB uses these and prepared a listing of the alternatives as shown below. If there are users who test these and prefer the more Standard ones, I can create an AppImage at the same time as what is released. It is currently at: https://cinelerra-gg.org/download/testing/modified_shortcuts.AppImage --------------------- Changed shortcuts to Standard Shortcuts - only English version for the caption/hints. The texts in the menu and the captions of the icons, written with the '-' character between the Special key and the key, for example "Shift-s", have been replaced by the '+' character. And the letters are always in capital letters although Shift is not pressed. Many, if not all the other NLE programs use this notation. Some shortcuts like "BD Render... (Ctrl+Shift+d)" and "DVD Render... (Alt+d) have been deleted because they are not used frequently. These shortcuts are very useful because the keys more frequently used have priority in editing: one hand (left) on the keyboard and the other hand (right) on the mouse. /* ********************************************************************** */ Goal: Changing some shortcuts to a NLE's standard shortcuts. For example: J - K - L (Play Normal reverse - Stop- Play Normal forward) if pressed twice J (or L), its Play Fast or Normal. I - O (InPoint - OutPoint) A - S (Jump backwards next cut - Jump forwards next cut) If an shortcut on After column has a '+' symbol (for example: + 'I'), it means that it is added to the old shortcut/s on Before column and also that that shortcut has been take from an old shortcut (of course), which it has another key. ----------------------------------+-------------------+-------------------+ Description | Shortcut | Before | After ----------------------------------+-------------------+-------------------+ -To clip | 'i' | Ctrl+I -Scroll window timeline... left | LeftArrow, ',' | LeftArrow -Scroll window timeline... right | RightArrow, '. | RightArrow -Label | 'l' | ''' (single quote) -Go to | 'g' | Ctrl+G -Generate keyframes... tweeking | 'j' | 'G' -Jump forward... next Keyframes | 'k' | Shift+Right Arrow -Jump backwards... next Keyframes | Shift+K | Shift+Left Arrow -New Project... | 'n' | Ctrl+N -Load files... | 'o' | Ctrl+O -Save | 's' | Ctrl+S -Save as... | Shift+S | Ctrl+Shift+S -Save Session | Ctrl+S | (null) -Select-> All | 'a' | Ctrl+A -Deselect All | 'a' or null | Ctrl+Shift+A -Select Edits | Ctrl+Alt+' | Ctrl+Alt+A -Undo | 'z', Ctrl+Z | Ctrl+Z -Redo | Shift+Z | Shift+Z -InPoint | '[', '<' | + 'I' -OutPoint | ']', '>' | + 'O' -Play Normal reverse | NumKP 6, Alt+O | + 'J' Normal&Fast -Play Stop | NumKP 0, Alt+M | + 'K' -Play Normal forward | NumKP 3, Alt+L | + 'L' Normal&Fast -Jump backwards to the next cut | Alt+LeftArrow | + 'A' -Jump forwards to the next cut | Alt+RightArrow | + 'S' -One Frame back | NumKP 4, Alt+U | + ',' (comma) -One Frame forward | NumKP 1, Alt+J | + '.'

How to put new transitions in the appimage?
by Andrea paz 26 Sep '23

26 Sep '23

I received a request to put a button that would serve to put new transitions directly into the appimage. In your opinion is it possible or do you have to go through manual unpacking and subsequent recreation of the appimage?

I have a question about the Cinelerra-GG Forum rules
by Doug Magill 23 Sep '23

23 Sep '23

I have a question about Cinelerra-GG's Forum rules, I do not understand the statement "In particular the legal regulations are to be considered after German right.", what does this statement mean? Are you guys members of some German far right organization or something? I am Canadian and I do not understand what the statement "In particular the legal regulations are to be considered after German right." means, please clarify.

Repair some TODO from latex source
by Andrea paz 23 Sep '23

23 Sep '23

I made changes in windows.tex to eliminate the second TODO present in the Latex code. I also made other changes and small additions. See if they are okay. The third TODO refers to the creation of a real table from a list. We can see this list in the attached figure. I don't know how to make the table because I don't understand what its contents represent and what it is for. Can someone explain it to me? The section is as follows: https://cinelerra-gg.org/download/CinelerraGG_Manual/User_Folders_Bins.html There is a nice tutorial on this topic (in Spanish): https://www.youtube.com/watch?v=hjrSTjl1-M0&list=PLOnHGAy9DoU1Xaj9HVhBwyov-… And also the text version, whose translation is more convenient: https://andalinux.wordpress.com/2020/12/17/cinelerra-gg-21-ordenar-archivos…
