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.

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.

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.

Again on plugins in floating point (HDR)
by Andrea paz 23 Jan '24

23 Jan '24

I tried to make other changes to the plugins for Color Correction to be able to make it also see out-of-range (HDR) values and be able to change them. All of this involves floating point calculation. I tried changing the range of the following plugins: Alpha; Color3Way; ColorBalance; Gradient; Histogram Bezier e Overlay. If interested, I can report attempts to modify the code, but I got good results only with Color3Way. More in detail: Alpha: My modifications ruin the plugin. Probably widening the range 0 - 1.0 leads the algorithms to wrong results. However, I think the original plugin works in floating point. ColorBalance: From my tests I did not notice any difference with the unmodified plugin (I used an appimage). I am under the impression that this plugin already works in floating point and does not need modification. Gradient: Here again I find no difference with the original plugin. Again, I have the impression that the plugin already works in floating point. Overlay (shared effect): I don't notice any difference with the original plugin. Histogram Bezier: I tried extending the range similarly to Histogram (which works well in HDR, after modification). In this case I see no change. The code is much more complex and it is probably not enough to delete the CLAMP. The change I made is to the file "bistogram.C" line 361 I changed the value of 1.0 to 10.0. I also tried editing the file bistogramconfig.C line 110 e 111 I changed the value of 1.0 to 10.0. line 229 I changed the value of 1 to 10. I put these details because the plugin is very important for CC and I would love it if someone more experienced than me could make it work on out-of-range data as well. Besides, the plugin is not only a histogram but also uses the very important "Curves". For the Videoscope plugin I could not make changes because the code is too complicated for my skills; similarly to Histogram Bezier. Finally I describe Color3Way, in which the modification worked. In the original plugin the color wheels already seems to work in floating point, but not the V bar of brightness values (which are clipped). With the modification the V bar also works on out-of-range data. The modification is as follows: File "color3way.C": line 281 I changed the value of 1.0 to 100.0. line 284 I changed the value of 1.0 to 100.0 (I have also tried other values, e.g., 10.0, and the clamp always works up to those values). The floating point calculation works for both the saturation bar and the V bar. With the tests done so far, I have had no problems or errors/warnings on the terminal. I did the tests with exr images and then enabled the internal CinGG engine (but in the tests it also works with "ffmpeg first"). I set the color model to RGBA-FLOAT (inescapable: with integer 8-bit models you cannot have HDR) and the color range to 2020 NCL (but it works with all possible settings, not relevant). The graphics driver is X11 because with X11-OpenGL it does not work. Used patches: 0001-TEST-Simpler-unlimited-float-overlay.patch 0002-Allow-negative-numbers-in-overlayer.patch noclamp_in_histogram.diff Manual changes in color3way.C I am happy with the success with Color3Way (as with Histogram) because I believe it will become increasingly important to work on HDR video in the future. On the other hand, I regret not having success with Curves (Histogram Bezier) because it is an essential plugin for CC.

Set stream sample aspect ratio in ffmpeg.C
by Andrew Randrianasulu 15 Jan '24

15 Jan '24

Now it seems to display correct (16/9) DAR for sample encoded directly from hdv. (but for speed I tested vp8/webm, not av1/webm)

flac.webm profile does not work anymore?
by Andrew Randrianasulu 09 Jan '24

09 Jan '24

Looking at Terje's problem with libvorbis audio I noticed flac.webm profile does not work, and ffmpeg 4.4.4 already complaining you can't put flac audio in webm. So, I guess we better to remove this profile?

AOM 3.8, again
by Andrea paz 03 Jan '24

03 Jan '24

I have compiled with both aom 3.8 and aom 3.6 patches without errors. The rendering test results are: aom 3.4: 34 fps aom 3.6: 39 fps aom 3.8: 48 fps The speed increase is noticeable. The videos result visually of the same quality. aom 3.4 and 3.6 give files of equal size while aom 3.8 gives a slightly smaller file.
