Less confusion. > Einar Thanks for the responses; glad to hear from you again. In the CVE readme you mention the internal 16-bit color model. Since you remain the only deep Cinelerra expert (besides Adam, with whom it is difficult to interact), may I ask you to explain how color works in Cinelerra? Is it converted continuously as needed? Does each plugin make the conversions it needs? What do the color model settings affect and what are they affected by? Is it possible to implement ICC profiles? In short, I am not clear about anything related to color treatment in Cinelerra. This is an issue that we have been dragging around for years (for example see the thread: https://www.cinelerra-gg.org/forum/help-video/yuv-to-rgb-conversion-issues/) but the confusion is total and we can't figure it out. Few mentions were made many years ago: https://lists.cinelerra-cv.org/pipermail/cinelerra/2018q4/009903.html https://www.mail-archive.com/cinelerra@skolelinux.no/msg13761.html

May I ask why you removed The ColorSpace plugin from CVE? Is it not working well?

July release of AppImages
by Phyllis Smith 31 Jul '22

31 Jul '22

The AppImages for July are now available at: https://cinelerra-gg.org/download/images/ Unfortunately, the upgrade of OpenEXR as credited to Manuel V can not be done because I struggled and struggled to find a way to use "without-openexr" to also exclude Imath and could not find a way even tried checking cmake version to exclude and it still uses "forced" for Imath. I do not want to prevent older distrros having "cmake" lower than the required 3.12 from building; as long as they can build correctly "without-openexr'". Hopefully, a solution is still viable. Next following the work of Andrew and testing by Andrea will be testing the FFmpeg 5.1 upgrade. ********************************************************************************************************** *GIT for Cinelerra-GG has the following changes from 07/01/2022-07/31/2022* Library upgrades for the following: Libaom to 3.4.0 from 3.2.0 Libvpx to 1.12.0 from 1.11.0 Minor patches to configure.ac for needed configuration changes by Andrew.

Checked into GIT updated libraries
by Phyllis Smith 29 Jul '22

29 Jul '22

As Andrew provided patch updates and I checked on older versions of O/S (Ubuntu 16 and 32-bit Debian 9.1) the following have been updated: libaom-v3.4.0 (from v3.2.0) libvpx-1.12.0 (from 1.11.0) Be aware that if you switch back and forth between an older and newer version BE SURE TO "rebuild index" on you media file or you will see weirdness like I did because the rendered file is a different size between the old library version and the new library version. This will not be a problem for most people - probably just testers who use the same file names (like I always do!) Also, note that I will try to remember to "Credit" the comment in Git with the author because someone noted that that was not being done in Git. I had always put it in the Releasenotes.pdf as the appropriate place because seen by more people. Only programmers or users who do their own builds ever look at Git, but many more people look at the release notes because they want to see whether or not it is necessary to update to the latest release. So for example this latest checkin has the comment of: "Credit libaom/libvpx teams and Andrew patch update" You can stop reading this now, but I have to say in my defense on this Git oversite is that Git was created by Linus Torvalds (in Europe so was not known in the United States right away) in the year 2005. Although that was 17 years ago, it was not even available during our professional working years where we started out with Control Data Corporation and Cray mainframe computers. So basically the common consensus on the "proper" use of Git checkins is not even on my radar. End of rant!

Due to massive lib updates patches weight 23 mb! https://cloud.mail.ru/public/xZGW/K8FctMtP3 (Note, I tried to update mpegts muxer using my earlier single.diff from May, 5th - for encoding you need to modify bluray profile ...)

Monitor profiling
by Andrea paz 09 Jul '22

09 Jul '22

Hi, I don't know how many users do monitor profiling (I remember an old discussion with Pierre...). It has been a long time since I did it but now that I tried to do it again I have unsatisfactory results in terms of brightness. The DeltaE is great (0.35) but the gamma is really high, such that it hurts the eyes after a short time. Also, the custom calibration disables the brightness/lightness OSD controls so I can't lower it. I used the Rec709 color space which has gamma 2.4 instead of the normal 2.2 value of the sRGB space. Actually with a higher gamma you should get darker results. My monitor (Dell UO2716D) is a wide gamut type and natively supports various color spaces: sRGB; Rec709; AdobeRGB and DCI-P3 (98%). It should have no problem with Rec709 at gamma 2.4. Can you explain why I get too bright a result? I use Argyll CMS with DisplayCAL and Datacolor Spyder5 colorimeter.

blds/bld_prepare.sh update
by mnieuw＠zap.a2000.nl 04 Jul '22

04 Jul '22

Hi, attached is an update blds/bld_prepare.sh script. It has two changes: - Extra entries to install the patchelf, boost_regex and boost_filesystem packages. - A fix for Suse, the test for the link was failing. @Andrea, did not have time to add an Arch/Manjaro section. Suse installs all packages, but it fails on the linking stage of the new makeappimage tool. Have to look at it. MatN
