Hi all, it seems that the AppImage DL page link is broken, do you know where to find it? https://cinelerra-gg.org/download/images/ Thx, Bests, Camille.

AppImage build log?

Saw this in archived mailing list, but I never saw the actual email from Rob Prowel: Rob Prowel <https://www.mail-archive.com/[email protected]&q=from:%22…> Sun, 16 Nov 2025 17:18:33 -0800 <https://www.mail-archive.com/[email protected]&q=date:202…> > Does the AppImage image contain active and working CUDA/nvenc or is it > just a fallback to CPU encoding?

Rob, the AppImages are created on computers with different graphics cards/capabilities then what a user may have and therefore you will not get the same nvenc/CUDA speedups unless you built the binary yourself. There seems to be no way to create an AppImage that accomodates all of the variations.

Compositing two layers with transparency and chroma key
by Stefan de Konink 17 Nov '25

17 Nov '25

I want to achieve the following animation: - Track 1: the CGI animation, it has transparency and a chroma layer - Track 2: Video the animation runs over - Track 3: the CGI animation transitions to Track 1 + 2 = the default operation, this works when stacking the animation on top of the video. But *without rendering twice*, how am I able to mask out the chroma key in the animation, so track 3 becomes visible under it? -- Stefan

AppImage build log?

Does the AppImage image contain active and working CUDA/nvenc or is it just a fallback to CPU encoding? My testing seems to indicate the latter, as I'm seeing zero difference in encoding times between libx264 and nvenc. My ffmpeg transcoding scripts always show about a 1/6th encoding time when using nvenc.

Clodflare-backed services only works with some providers in Russia?
by Andrew Randrianasulu 13 Nov '25

13 Nov '25

Georgy noticed he can't clone from new Cineleraa-gg git server. Even switching to https not resulted in working copy. (it worked for me after I switched from git to https) I am not sure what can be done at server end, if cloudflare's whole network blocked here on our end ..May be teach github to sync automatically? https://faun.pub/github-sync-31dede07c606 may be something from this article? ==== Step 4: The Actual Sync The actual sync is easy enough — rebase and push to both remotes: # .github/actions/sync-branches/action.yml - name: Sync Branches shell: bash run: | for branch in ${{ inputs.branches }}; do echo "Syncing $branch..." # Start from local branch git checkout -B $branch origin/$branch # Rebase changes from mirror git pull mirror-ssh $branch --rebase # Push to both repos git push primary-ssh $branch git push mirror-ssh $branch echo "✓ $branch synced" done [...] Native Git Mirroring git clone --mirror source.git git push --mirror destination.git ==== end of quotation === Configuring side (ssh keys etc) look a bit intimidating for one line script kiddie like me :/

Documenting steps to create new AppImages (just in case needed)
by Phyllis Smith 12 Nov '25

12 Nov '25

What I have been doing to create new AppImage releases for Cinelerra-GG (basically these are what I call Moderator tasks). Neither difficult nor time-consuming. - as provided or updated, commit any changes to GIT source and GIT manual on server - update msg/txt to describe more noteworthy items in the release and checkin - create a new PDF and HTML manual version so it has the current date - update the Release Notes in Office Writer and create PDF file to put on website - build new binaries of CinGG for a) most used generic x86_64 with libsvtav1 and opencv built on fedora 32 b) ubuntu 16.04 for older x86_64 with libaom 3.4 instead of 3.8 c) same for ubuntu 16.04 with alternative shortcuts d) debian 11 32-bit for newer i386 with libsvtav1 e) debian 9.1 32-bit for older i386 (requires special export ac_cv_header... and FFMPEG_EXTRA_CFG...) - copy all of the HTML manual files to the newly built bin/doc/CinelerraGG_Manual for Help inclusion - create AppImages using linuxdeploy from the binaries - make tgz files of the CinGG source and HTML Manual files to put on the website - 10 files are moved to /tmp on the server via firehoze, or scp, or rsync (firehoze was needed in the past to get multiple network streams as numerous packages for all of the various distros and distro versions were moved over but that has been replaced by the generic AppImages). On the server, copy files from /tmp to final location which involves some tar extracts, deletions, and replacing files. - set tags on GIT for both the source and manual to note a new release version update - update News in WordPress on website and notify Mailing list of release

Calf plugin
by Andrea paz 11 Nov '25

11 Nov '25

I may have sent an email to the old list (I don't know!); I'll try to repeat it here: I noticed that the calf plugins work but without UI. While trying to investigate, I found this issue: https://gitlab.archlinux.org/archlinux/packaging/packages/calf/-/issues/3 Does this only affect Arch Linux because it is removing GTK2, or could it be a more general problem?

In Memoriam: W.P. Morrow (Good Guy)
by Sam 10 Nov '25

10 Nov '25

Early last week marked the fifth anniversary of Bill Morrow's passing, our esteemed developer and friend, who tragically lost his life in a bicycle accident. Five years have passed, but his legacy lives on in every line of code he wrote for Cinelerra-GG. Bill's passion for free software, his creative solutions, and his tireless commitment to the community shaped this project. He never hesitated to tackle even small improvements if they made users' lives easier. In his spirit and in the spirit of Phyllis and all the other supporters and helping hands, we want to continue advancing the project. The new server and the new mailing list are already up and running – a few details still need to be finalized, but that's coming soon. This modernized infrastructure and updated software will make Cinelerra-GG future-proof and support the community even better. Bill would have been delighted with this development – it corresponds exactly to his commitment to continuous improvement. I thank you for your patience – the migration took a bit longer than planned due to technical issues. What remains is the memory of an outstanding developer and a wonderful person who worked selflessly for the cause of free software. Through his work, he made this world a bit better. Heartfelt thanks go to the entire community that has carried and supported this project over all these years. I deeply appreciate Phyllis's work, and I'm sure many others in the community do as well – my sincere thanks go to Phyllis for her wonderful support. We also extend our gratitude to Adam Williams, the original creator of Cinelerra, for his brilliant idea and groundbreaking work, and to all those who have contributed to this codebase over the years, including those who have extended the code in other forks. Special thanks also to the new developers who continue to advance the project with their commitment and contributions – Bill would have been very happy about you and would have been proud of how you are continuing his work. Together, we keep Bill's vision alive. Thank you for everything, Bill. We miss you. Sam
