https://forum.level1techs.com/t/kdenlive-is-superior-to-davinci-resolve/140… from mid-2019, so not very fresh.. but I found idea about ==== No worries. I set up an inotifywatch script that transcodes media I write into an ingest folder on-the-fly, preserving the h264 codec but converting AAC to PCM_S24LE embedded audio. It’s automatic, mostly, and it’s quite neat. I don’t mind this part of things. ==== potentially interesting for other scenarios.... I also found forum post from oct. 2020 about kdenlive and nvenc not working (on dual-gpu system). I followed link there and double-checked visually our h264_nvenc profile... it look sane... https://forum.manjaro.org/t/insane-ly-slow-render-times-with-kdenlive/30367… also found (probably already referenced) thread about (lack of) 10 bit support in mlt/kdenlive, in context of 8k editing (again, year happened since this was written, so may be some progress already was done) https://www.mail-archive.com/[email protected]/msg10854.html also, COMPLETELY offtopic but this article tries to explain why (Adobe's) After Effects eats so much memory, with some explanation about caching in memory and on-disk: https://www.google.com/amp/s/www.provideocoalition.com/after-effects-perfor…

background render tip
by Andrew Randrianasulu 28 Jul '21

28 Jul '21

While working on EDL support I noticed old Adobe Premiere (4.0, 4.2) had interesting mode where you can output .mov from pre-rendered (with effects, transitions, etc) workarea. In CinelerraGG you can get similar effect by setting background render to jpeg, making sure your whole project got its preview (red bar) rendered, then quit cin and execute something like this: $ ffmpeg -f image2 -i ~/tmp/000%3d -c:v copy brender.mov it will copy your background render jpegs into mov without re-encoding them you might want to add '-r' too for specific framerate. I wonder if libavformat-based mov muxer can be re-introduced for such task .. (not feature request, just thinking). And may be 'delete brender files' button (there seems to be some space in preferences/performance GUI window..)

I tried to make very crude patch (attached), it seems to work but may be you dislike double directory creation (first pathname + "_" dir, then "/Proxy/" inside it?) feel free to simplify...

termux patch series - another try
by Andrew Randrianasulu 24 Jul '21

24 Jul '21

there might be some whitespace errors in randrik12/0053-fix-mjpegtools-patch4-and-patch5-termux.patch - try to set git am to --whitespace=nowarn for this patch.. may be autofix (whitespace=fix) breaks them

I have to close it with ctrl+c. i was assuming you used 'git apply -v dir/*.patch' from cingg's source dir, where dir/ inside cingg src root, with my patches. just 'git apply -v' probably wait for std. input or something... > > Reading Phyllis' email I wonder if the 3 patches of x265 that I find > in.../cinelerra-5.1/thirdparty have been applied or I have to apply > them like the others of randrik10. > they *should* be applied automatically... by buildsystem. just be sure they live in thirdparty/src and named like same_name_as_src_tar.patch[1,2,3]

latest hacks
by Andrew Randrianasulu 21 Jul '21

21 Jul '21

this time as tar.gz because adding (or downloading) 50+ files a bit of chore.. based on mainline c0251c4aa075 mostly same old patches for termux + few even older hacks.. Andrea, I broke my cpu_debug patch into 3. randrik9/0047-Debug-add-printing-of-cpucount-from-ff_cpus.patch randrik9/0048-Debug-add-cpu-count-printing-for-mwindow.C.patch randrik9/0049-Hack-raise-cpu-cap-from-8-to-16.patch can you (and Phyllis) see if just 0049 gives you better result? if possble please also test non-ffmpeg based MPEG encoding and decoding...

offtop: new rt kernel?
by Andrew Randrianasulu 21 Jul '21

21 Jul '21

saw ref. to this from Phoronix forums.. ===copy== XanMod is a general-purpose Linux kernel distribution with custom settings and new features. Built to provide a stable, responsive and smooth desktop experience. The real-time version is recommended for critical runtime applications such as Linux gaming eSports, streaming, live productions and ultra-low latency enthusiasts. Supports all recent x86_64 versions of Ubuntu / Debian-based systems. Note: The current proprietary NVIDIA, VirtualBox, VMware Workstation / Player and some other dkms modules builds do not officially support Clang'ed (EDGE) and RT kernels. ===copy end== site https://xanmod.org/ I wonder how it may interact with Cinelerra(s) - because there we use threads and some internal scheduling tricks....
