2.6. Other Options and Other Windows ================== 2.6.1. Transport Controls ------------------------- I don't think the last sentence in the following excerpt from page 94 is true: > The keyboard > interface of either the numeric pad or alternative keys has more speeds with the > addition of Forward Slow(2) and Reverse Slow (5). Hitting any key on the keyboard > twice pauses it. It seems that the only key that pauses playing is the space bar, and you only have to press it once to stop playing. In the above excerpt, a space should be placed between "Forward Slow" and "(2)". 2.6.2. Zoombar -------------- On page 95, the User Manual explains that "a Ctrl-click in the video output zooms out." > The zoom toggle also causes the Compositor window to enter zoom mode. In > zoom mode, clicking in the video output zooms in while a Ctrl-click in the video > output zooms out. Instead, it does the opposite: it also zooms in. The last sentence in this section left out a period at the end. 2.6.3 Show Overlays ------------------- I think we can change the second sentence on page 96 as follows: The color is not changeable for -the 3 items of Mode, Pan, and Mask which simply display their symbol icon. +the 4 items of Mode, Pan, Mask, and Hard edges which simply display their symbol icon.

cingg for NetBSD pkgsrc update
by Andrew Randrianasulu 03 Jul '24

03 Jul '24

well, I tried to update my wip patches adding cinelerra-gg as pkgsrc module for NetBSD. So far it sets architectures to just i386 and amd64, but in theory you can try it on arm8l (32bit arm) and aarch64 and ppc too (but I only have qemu-emulated PPC machine so builds tend to be on slow side - I only tried to build our sources on Debian 8.11 for ppc and there build was fine but cingg crashed at startup just after splash screen) I hope that someone with relatively fast ppc machine can give it a spin? On i386 it builds ok with 1024 Mb of ram. two virtual cores. qemu-system-i386 -cpu pentium2 -accel kvm -hda netbsd-92.qcow -smp 2 -device ES1370 -boot c -netdev user,id=myslirp,ipv6=off -device e1000,netdev=myslirp -m 1024 (qemu 9.0 on Slackware 15.0 i586) it also loads and plays mpeg2 video file (slowly) if I run qemu this way: qemu-system-i386 -cpu pentium2 -accel tcg,thread=multi -hda netbsd-92.qcow -smp 2 -device ES1370 -boot c -netdev user,id=myslirp,ipv6=off -device e1000,netdev=myslirp -m 1024 or qemu-system-i386 -cpu pentium -hda netbsd-92.qcow -device ES1370 -boot c -netdev user,id=myslirp,ipv6=off -device e1000,netdev=myslirp -m 512

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.

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

ffmpeg -hwaccel AV1 QSV encoding on Arc GPU executes rapid, but commands?

Late last year I posted a thread "[Cin] Prepping HW upgrade options for AV1 de-/encoding" https://www.mail-archive.com/cin@lists.cinelerra-gg.org/msg06626.html and there have also been other threads about hardware acceleration So here again, I also wanted to give it a first try with ffmpeg -hwaccel AV1 QSV encoding.

This didn't seem to change the file size compression compared with the defaults (without setting preset) Some visible artifacts (mosaic and stuttering ) is seen during zoom and pan in the hdv file; probably due to hard compression and/or the memory allocation error messages, I would guess. ------------- In short, I have tested the same SD-DV 576i and HDV 1080i video files as with SVT-AV1 (CPU based) in another resent post. ffmpeg -hide_banner -hwaccel qsv -qsv_device /dev/dri/renderD128 -i dv01_07.dv -c:v av1_qsv -preset 4 dv01_07_av1_qsv_pr4.webm frame= 2832 fps=2106 q=-0.0 Lsize= 10554KiB time=00:01:53.24 bitrate= 763.5kbits/s speed=84.2x fmpeg -hide_banner -hwaccel qsv -qsv_device /dev/dri/renderD128 -i hdv09_04.m2t -c:v av1_qsv -preset 4 hdv09_04.m2t_av1_qsv_pr4.webm frame= 5913 fps=700 q=-0.0 Lsize= 48022KiB time=00:03:58.77 bitrate=1647.6kbits/s dup=0 drop=4 speed=28.3x du -sh dv01_07* 389M dv01_07.dv 11M dv01_07_av1_qsv_pr4.webm 24M dv01_07_svt-av1_pr4.webm 27M dv01_07_svt-av1_pr6.webm 28M dv01_07_svt-av1_pr8.webm 31M dv01_07_svt-av1_pr10.webm 33M dv01_07_svt-av1_pr12.webm du -sh hdv09_04* 745M hdv09_04.m2t 47M hdv09_04.m2t_av1_qsv_pr4.webm 111M hdv09_04_m2t_svt-av1_pr4.webm 119M hdv09_04_m2t_svt-av1_pr6.webm 118M hdv09_04_m2t_svt-av1_pr8.webm 125M hdv09_04_m2t_svt-av1_pr10.webm 134M hdv09_04_m2t_svt-av1_pr12.webm A warning output in both command lines is: [vist#0:0/dvvideo @ 0x556a3f679100] WARNING: defaulting hwaccel_output_format to qsv for compatibility with old commandlines.
