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

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.

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.

Error reports and discussions about section 2.5 of the User Manual
by Bulhwi Cha 30 Jun '24

30 Jun '24

2.5. Resources Window ========== 2.5.3. Modify Folder: sorting the media --------------------------------------- In the HTML User Manual, there's an empty item in the bulleted list showing the subsections: > Subsections > * > * Drag and Drop: > * Filters: On page 84 of the PDF User Manual, the "Enable" field is referred to as "Enabled": > Filters: you do automatic populating using filters (Smart Bins mode). You set > the values of the Enabled; Target; Op and Value fields to make up the required > filtering. On the same page, I'm not sure if the following explanation is correct: > When you click on the Value portion of that filter, the entire set of files that are > covered by the filter rules pops up. Nothing happens when I click on the Value portion of a filter. On page 85, "follows ." in the following sentence should be "follows." > Information about the columns and rules for the search filters in the Modify folder > window follows . On page 87, it'd be nicer if the table were properly formatted. On page 88, should we change the meaning of the third-to-last example of Table 2.2 to "files included all have 23 to 25 framerate"? 2.5.5. Resources Window Preview Mode ------------------------------------ On page 91, "until click it again" should be "until you click it again": > When you do, a line > will be drawn through the current preview mode so that you are aware > that it is > in No Play mode until click it again. 2.5.6. Moving clips/media from/to Resources window -------------------------------------------------- On page 92, what does "wipe the names" mean? > Obviously this Paste file list feature means you can create a list of files outside of > C INELERRA-GG using an editor, wipe the names, and then use Paste file list to load > them into the media Resources window. On page 93, shouldn't there be three additional media files, not six? > When that is done, the additional 6 media files > will be available on this other instance too. On the same page, I think "as the 5th item down" should be "as the penultimate item down": > 2. right click in an empty spot in the media folder and the popup shows snap- > shot as the 5 th item down On page 94, "the 6th menu item" should be "the last menu item": > Grabshot is the 6th menu item.

new cygwin patch for testing
by Andrew Randrianasulu 27 Jun '24

27 Jun '24

For some reason cinelerra/TESTS was both file (as seen in patch) and directory (git rm complained about impossibility to remove it)? Unfortunately, it still does not work at my end with plugins all returning bad exec format . :( For some reason new cygwin does not have desktop link to Openbox startup, but running startxwin from cygwin console started X server properly ...

ffmpeg -hwaccel AV1_VAAPI vs AV1_QSV encoding on Arc GPU
by Terje J. Hanssen 25 Jun '24

25 Jun '24

After posting some recent ffmpeg SVT-AV1 vs -hwaccel AV1_QSV encoding tests, here follows a simple comparison with AV1_VAAPI (and opus audio default). Comparable bitrates are used. The higher bitrate is selected on VAAPI's default bitrate premise. Preset 4 quality setting is used for QSV encoding, no other tuning or optimization is applied. The first visual quality is so far reasonable IMO, while there may be differences at a closer study. The ffmpeg command line syntax I got working for AV1_VAAPI is based on an VP9 encode (only) example at https://trac.ffmpeg.org/wiki/Hardware/VAAPI#Encode-only So far I didn't succeed trying to apply the Hardware-only Transcode examples. So the DV and HDV decode parts have possibly taken place in the CPU rather than in the GPU(?) https://trac.ffmpeg.org/wiki/Hardware/VAAPI#Transcode -------------------------- 576i SD-DV -> AV1_VAAPI at bv1570k VBR ffmpeg -hide_banner -vaapi_device /dev/dri/renderD128 -i dv01_07.dv -vf 'format=nv12,hwupload' -c:v av1_vaapi -b:v 1570k dv01_07_av1_vaapi_bv1570k.webm frame= 2832 fps=1959 q=-0.0 Lsize= 28133KiB time=00:01:53.28 bitrate=2034.5kbits/s speed=78.3x 576i SD-DV->AV1_QSV at bv1570k ffmpeg -hide_banner -hwaccel_output_format qsv -qsv_device /dev/dri/renderD128 -i dv01_07.dv -c:v av1_qsv -preset 4 -b:v 1570k dv01_07_av1_qsv_pr4_bv1570k.webm frame= 2832 fps=1746 q=-0.0 Lsize= 23852KiB time=00:01:53.24 bitrate=1725.5kbits/s speed=69.8x .......... 576i SD-DV -> AV1_VAAPI at default VBR ffmpeg -hide_banner -vaapi_device /dev/dri/renderD128 -i dv01_07.dv -vf 'format=nv12,hwupload' -c:v av1_vaapi dv01_07_av1_vaapi.webm frame= 2832 fps=1324 q=-0.0 Lsize= 81317KiB time=00:01:53.28 bitrate=5880.6kbits/s speed= 53x 576i SD-DV->AV1_QSV at bv5600k ffmpeg -hide_banner -hwaccel_output_format qsv -qsv_device /dev/dri/renderD128 -i dv01_07.dv -c:v av1_qsv -preset 4 -b:v 5600k dv01_07_av1_qsv_pr4_bv5600k.webm frame= 2832 fps=1713 q=-0.0 Lsize= 81600KiB time=00:01:53.24 bitrate=5903.1kbits/s speed=68.5x ....... du -sh dv*.dv dv*vaapi*.webm dv*qsv*.webm 389M dv01_07.dv 28M dv01_07_av1_vaapi_bv1570k.webm 80M dv01_07_av1_vaapi.webm 24M dv01_07_av1_qsv_pr4_bv1570k.webm 80M dv01_07_av1_qsv_pr4_bv5600k.webm In this SD-DV case, VAAPI encoding is 12% faster than QSV with 15% smaller file size at bv1570k bitrate, while QSV is 29% faster than VAAPI at bv5600k bitrate. ---------------------------- 1080i HDV -> AV1_VAAPI at 3700k VBR ffmpeg -hide_banner -vaapi_device /dev/dri/renderD128 -i hdv09_04.m2t -vf 'format=nv12,hwupload' -c:v av1_vaapi -b:v 3700k hdv09_04_av1_vaapi_bv3700k.webm frame= 5963 fps=631 q=-0.0 Lsize= 153106KiB time=00:03:58.77 bitrate=5252.8kbits/s speed=25.3x 1080i HDV->AV1_QSV at 3700k fmpeg -hide_banner -hwaccel_output_format qsv -qsv_device /dev/dri/renderD128 -extra_hw_frames 16 -i hdv09_04.m2t -c:v av1_qsv -preset 4 -b:v 3700k hdv09_04_av1_qsv_pr4_bv3700k.webm frame= 5963 fps=473 q=-0.0 Lsize= 113271KiB time=00:03:58.77 bitrate=3886.1kbits/s speed=18.9x ....... 1080i HDV -> AV1_VAAPI at default VBR ffmpeg -hide_banner -vaapi_device /dev/dri/renderD128 -i hdv09_04.m2t -vf 'format=nv12,hwupload' -c:v av1_vaapi hdv09_04_av1_vaapi.webm frame= 5963 fps=629 q=-0.0 Lsize= 153106KiB time=00:03:58.77 bitrate=5252.8kbits/s speed=25.2x 1080i HDV->AV1_QSV at 12600k ffmpeg -hide_banner -hwaccel_output_format qsv -qsv_device /dev/dri/renderD128 -extra_hw_frames 16 -i hdv09_04.m2t -c:v av1_qsv -preset 4 -b:v 12600k hdv09_04_av1_qsv_pr4_bv12600k.webm frame= 5963 fps=476 q=-0.0 Lsize= 370043KiB time=00:03:58.77 bitrate=12695.6kbits/s speed= 19x du -sh *.m2t hdv*vaapi*.webm hdv*qsv*.webm 745M hdv09_04.m2t 150M hdv09_04_av1_vaapi_bv3700k.webm 375M hdv09_04_av1_vaapi.webm 362M hdv09_04_av1_qsv_pr4_bv12600k.webm 111M hdv09_04_av1_qsv_pr4_bv3700k.webm In this HDV case, VAAPI encoding is about 33% faster than QSV with 25% - 4% smaller file sizes.

I've been trying hard to love Cinelerra but it is pushing my limits. The main issue now is not being able to use my Nvidia GPU. I'm using POP_OS and FFMPEG verifies with my GPU. No configuration that I've tried takes advantage of my GPU. Any clues appreciated. Regards, David Koski

Audio-video desync in preview composition when applying F_atadenoise
by Stefan de Konink 21 Jun '24

21 Jun '24

Hi, When applying F_atadenoise I notice that the audio and video in the compositor upon *playback* is desynchronised. Rendering is not influenced, audio and video in the output file are in sync. I wonder, if an ensemble of plugins take longer to process, or even intentionally do so, shouldn't this be handled? -- Stefan
