AOM SVT-AV1 2.1 Released
by Terje J. Hanssen 17 Jun '24

17 Jun '24

According to Phoronix the Alliance of Open Media project quietly released (the Intel based) SVT-AV1 v2.1 last week. With this new SVT-AV1 release are yet more performance optimizations and tuning. The M0, M3, M5, and M6 presets are seeing 12~40% speed-ups while maintaining similar quality levels to prior releases. The compression efficiency of presets M11 to M13 meanwhile have improved by 1~2%. New SVT-AV1 benchmarks soon. https://www.phoronix.com/news/SVT-AV1-2.1-Released ---------- Meanwhile, I have updated my previous tests using ffmpeg-7 and libSvtAv1Enc2 version 2.0 on openSUSE Slowroll below. The results are about the same speed +/- compared as my earlier tests using ffmpeg-6 and SVT-AV1 encoder version 1.7 https://lists.cinelerra-gg.org/pipermail/cin/2023-December/007436.html (Else I have purchased the hardware components to upgrade and rebuild my workstations for a planned AV1 QSV/hw video transcoding: mobo, Intel cpu and gpu, memory, ssd, cooler. More about this later. But first I have to finish my ongoing DVD Video project).

A phrase is duplicated in the User Manual
by Bulhwi Cha 13 Jun '24

13 Jun '24

On page 74, section 2.3 'Viewer Window' of the User Manual, there's a sentence that duplicates the phrase "output size" as follows: > The Viewer uses the project’s output size output sizeentry format settings to dis- > play the media instead of the original asset’s format. I'm a newcomer to Cinelerra-GG, so I'm not sure how to fix this sentence.

ChromakeyHSV menu much improved
by Phyllis Smith 11 Jun '24

11 Jun '24

Checked into GIT an anonymous contribution for a much improved ChromakeyHSV menu to include: 1) Now there are individual boxes on the left side where you can either keyin a distinct value or use the up/down arrows to change the value. This gives you a much better control than where previously you could only move the slider to jiggle the number you wanted. Also, much easier to see what all the values are at once whereas before you had to click on each individual diamond setting to see just 1 value. 2) You can reset individual parameters to the default. Before you could only reset them all so you would lose a particular value you were already happy with. 3) The menu is more visible over a larger space making it easier to see. 4) Plus some minor code cleanup to eliminate at least 1 duplicate line and to put some "int" on same lines as statement. P.S. Someone indicated that ChromakeyHSV had some kind of bug, but I was wondering if Andrea ever found out exactly what that was? since it looks OK to me.

Fade In/Fade Out flash bug
by Andrea paz 09 Jun '24

09 Jun '24

In MantisBT #0559, Georgy took an in-depth look at how Dissolve works when the two affected clips have an alpha channel at different opacity (see comment 005645, for a detailed description). The purpose is to eliminate The flash of gray lettering just before having the normal Dissolve. Georgy explained the problem well. A patch appeared in CinHV to fix the problem but Georgy saw no difference between CinGG and CinHV with the same project (provided by IgorBeg). Investigating further he saw that the normal operation of Dissolve leads to the very flash we considered a bug. So the question is whether to leave it as is or make interventions to have a different result, more in line with expectations. Do you have any ideas/proposals on how Dissolve/Fade should work? https://www.cinelerra-gg.org/bugtracker/view.php?id=559

Will the LV2 Plugin interfaces in Cinelerra-GG be affected by the possible withdrawal of GTK2 from certained linux distribution?
by Pierre autourduglobe 06 Jun '24

06 Jun '24

A message from AVLinux (creator of AVL-MXe) on the MX Linux furum explains that the removal of GTK2 from the next stable release of Debian could affect the user interface display of certain plugins. He explains the problem and the source of the solution he intends to use for AVL-MXe. Will this problem affect the display of LV2 Plugin interfaces in Cinelerra-GG? https://forum.mxlinux.org/viewtopic.php?t=80745&sid=d86a25d93bc096a81fbf8ee…

A potential HTML manual problem under NTFS/FAT filesystems
by Georgy Salnikov 31 May '24

31 May '24

I accidentally found, that in the huge list of files produced by latex2html from the CGG manual there are HTML pages, whose filenames differ from each others in the letter case only. This is no problem under Linux. But if somebody copies all the files to a Windows computer (with an NTFS-like filesystem), or to a memory stick formatted as FAT32, or to some network (Windows or Samba) disk where differences between upper/lower case in filenames are ignored by the operating system, then some HTML pages will be overwritten by others and disappear. I have found 4 such potentially conflicting pairs of page names: Compositor_Window.html - describes the whole Compositor GUI (Chapter 2) Compositor_window.html - describes the Compositor shortcuts (Chapter 15) Viewer_Window.html - describes the whole Viewer GUI (Chapter 2) Viewer_window.html - describes the Viewer shortcuts (Chapter 15) Final_note.html - about copy/paste text highlighting in Chapter 17 (How some stuff works) Final_Note.html - a link to wiki.archlinux.org on hardware video acceleration from Chapter 19 (Performance and other tips) Index.html - the Index at the very end of the manual index.html - the default start page, automatically created by latex2html as the exact copy of (hard link to) CinelerraGG_Manual.html The automatic creation of index.html can be suppressed by the latex2html option -noauto_link, and this file is not used by CGG Context Help (while Index.html is used). If renaming other sections (for example "Compositor window" to "Compositor window shortcuts" or "Final Note" to "Further topics on hardware acceleration", or something like this) is desirable, to me is open question.
