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

Not quite correct patch for toggling various windows from mainmenu->window submenu

Well, I'm fairly sure void MWindow::hide_vwindow() kinda wrong (because copypasta!) but it seems to work for single viewer window I wanted to hide via this menu.

Is the Waveform properly calibrated ?
by Pierre autourduglobe 27 Nov '20

27 Nov '20

When I analyze a sequence of SMPT ntsc SD color bars generated by my DV camera. The Waveform correctly indicates that the black bands are at 7.5 IRE but places the white band at around 92 IRE instead of 100 IRE and the colored bands around 70 IRE instead of 75 IRE... This in a project in DV ntsc YUV 720x480 format with the preferences "YUV colors space" to BT601 and "YUV color range" to JPEG. If you choose instead the preference "YUV color range" in MPEG, the white band is correctly at 100 IRE and the colored bands are 75 IRE, but... the black bands are now wrongly at 0 IRE... So no possibility to have a good reading. This is true whether I use the X11-OpenGL video driver or just X11. I got the same results (problems) using the color bar from the Grass Valley site: http://www.gvgdevelopers.com/K2DevGuide/Clips2/NTSC_SD_DV25_colorbar.avi http://www.gvgdevelopers.com/K2DevGuide/Clips2/NTSC_SD_DV50_colorbar.avi http://www.gvgdevelopers.com/K2DevGuide/Clips2/NTSC_SD_DVCAM_colorbar.avi Is the Waveform properly calibrated ?

Missing preset for SD 16:9 Anamorphic Wide DV(D)
by Terje J. Hanssen 27 Nov '20

27 Nov '20

While HDV and FHD video can rendered for Blu-ray media, the widespread DVD can only playback SD video content. HDV camcorders can during tape playback 1440x1080 anamorphic HDV content, downconvert it to Widescreen Anamorphic 16:9 video. Is it possible to get a Preset for DV(D) wide 16:9 video? References ------------------ MPEG-2 DVD-Video (Application) https://en.wikipedia.org/wiki/MPEG-2#DVD-Video 16:9 is the only widescreen aspect ratio natively supported by the DVD format. Anamorphic DVD transfers store the information as 5:4 (PAL) or 3:2 (NTSC) square pixels, which is set to expand to either 16:9 or 4:3, which the television or video player handles. For example, a PAL DVD with a full frame image may contain a video resolution of 720×576 (5:4 ratio), but a video player software will stretch this to 1024×576 square pixels with a 16:9 flag in order to recreate the correct aspect ratio. https://en.wikipedia.org/wiki/16:9 ------- DVD Video - Widescreen Anamorphic 16:9 16x9 A DVD labeled as "Widescreen Anamorphic" contains video that has the same frame size in pixels as traditional fullscreen video, but uses wider pixels. The shape of the pixels is called pixel aspect ratio and is encoded in the video stream for a DVD player to correctly identify the proportions of the video. If an anamorphic DVD video is played on standard 4:3 television without adjustment, the image will look horizontally squeezed. Although currently there is no labeling standard, DVDs with content originally produced in an aspect ratio wider than 1.33:1 are typically labeled "Anamorphic Widescreen," "Enhanced for 16:9 televisions," "Enhanced for widescreen televisions," or similar. If not so labeled, the DVD is intended for a 4:3 display ("fullscreen"), and will be letterboxed or panned and scanned. https://en.wikipedia.org/wiki/Anamorphic_widescreen#DVD_Video Terje J. H

DNxHR presets
by Andrea paz 26 Nov '20

26 Nov '20

I tried to put DNxHR presets under the .mov container. The advantages of using this mezzanine codec are great quality and efficiency (like ProRes) and being self-managed for each resolution and bit-rate (unlike DNxHD which has many fixed and unalterable formats for each resolution). The only disadvantage compared to DNxHD is that it supports only progressive and not interlaced signals. If someone wants to try them, I make them available (there are also 2 audio presets of type pcm). They seem to work apart from some settings: - Pixel_format gbrp10le of pulldown ("pixels:") does not work (it remains yuv type). - in pixel_format pulldown there is no choice for bit-depth=12; while DNxHR_HQX and DNxHR_444 profiles should be 12-bit (for resolutions higher than FullHD). Is this a limit of CinGG? - pix_fmt=rgb24 does not work. Since I can't find any official documentation, if you have any advice please say so. I based on these articles: https://dovidenko.com/2019/999/ffmpeg-dnxhd-dnxhr-mxf-proxies-and-optimized… https://macilatthefront.blogspot.com/2018/12/tutorial-using-ffmpeg-for-dnxh…
