Tool for timelinging and multitrack exports
by Stefan de Konink 29 Jan '23

29 Jan '23

Hi, I think this scenario has passed by on the mailinglist before, and I might because of how I work, be more attracted to these kinds of problems than others that mainly do non-linear work. After the recording, and after getting the main production idea, my projects are timewise mostly influenced by reconstruction of a multi track linear timeline. I am using multiple camera's that don't use any (world) timecodes, and have 2GB limitations. So the best thing they can do is giving me a relative timestamp by means the filename or creation_time metadata. What I would be interested in is the ability to: 0. having a forever scrolling canvas, canvas may do tricks like hiding places where no content is available 1. "automatically" construct such timeline each track(group) being from a single device, which typically atomically can only produce a single stream of content by means of metadata 2. having some tooling that can do macro alignment, independent of metadata (for example by audio fingerprinting) 3. having some tooling that can do micro alignment 4. export this in either some EDL format or multitrack format being NLE independent I wonder what other people are using for the above, other than pen and paper. >From my own experience within Cinerella (I know about mixers) I don't end up with the workflow that I want for non-continious recordings. A second email follows on a different workflow issue. -- Stefan

two more patches
by Andrew Randrianasulu 28 Jan '23

28 Jan '23

One alter bsd.bld for telling configure to use clang (on freebsd), so build spew less warnings there. Second patch raises libvpx limit for internal ffmpeg, so you can test it on monster machine (do not forgot to alter vp9 profile a bit so it will try to use more threads)

by Andrew Randrianasulu 28 Jan '23

Well, our link [0] only gives access to late CinCV TNG (?) archives since 2014 There was more history. Currently i tried to wget -m https://web.archive.org/web/20110511132711/https://init.linpro.no/pipermail… and got 100 Mb big mbox! (2003-2011) I also try to archive this one https://web.archive.org/web/20200710015535/https://lists.skolelinux.org/pip… (2003-2019) I do not know how to get full archive from narkive or mail-archive.com [0] https://lists.cinelerra-cv.org/pipermail/cinelerra/ - linked as "Cin-CV email archive complete Here you can find the complete Cinelerra-CV email archive." I think we have bug in bugtracker about this .... https://www.cinelerra-gg.org/bugtracker/view.php?id=132 ah, lol, Terje pointed cin-cv archive was just under different directory "old Cin-CV(S) email Archive: 2001 (mainly 2003) - 2016 https://lists.cinelerra-cv.org/pipermail/cinelerra-skolelinux/" always nice to have more than one archive

IgorBeg did a great job of revising the Proxy section of the manual. I have put it in Latex, see if that works for you. I take this opportunity to remind you that the CinGG manual is a "work in progress", if you would like to help revise and improve it, you are welcome. PS: I am also attaching Igor's odt version so you can all read it and see the nice work done and also propose changes.

I tried to fix NetBSD build without breaking FreeBSD, Linux and termux.. It seems I successed! Attached patches builds (and runs) on NetBSD 9.2 I386 FreeBSD 12.3 amd64 Slackware 15.0 i586 Termux aarch64 all without-thirdparty for saving build time. Can you test them on your usual systems?

Complete system hangs (likely out of memory)
by Stefan de Konink 25 Jan '23

25 Jan '23

Hi, When editing with Cinelerra (current git) I experience frequently that my entire system hangs after scratching through either the timeline or the viewer. As experienced before I have noticed that Cinerella eats a lot of memory. The total amount of assets I have currently in my project is about 70GB, my system memory is 16GB, and yesterday I have added 8GB of swap (normally no swap). It seems that with every video that I preview my memory usage significantly increases, but is never released. I think we have discussed this behavior on the mailinglist before being that the indices never get released. But still the amount does not make sense to me. As user my expectation would be that when I would close the *viewer*, the memory would get released, especially when the content is not placed on the timeline. Are there any statistics available on the memory usage what goes where? Practical question: is it possible to have a different path for the emergency backups than /tmp? -- Stefan

Regarding memory leaks: > 1. Re: Complete system hangs (likely out of memory) > (Stefan de Konink) > 2. Re: Complete system hangs (likely out of memory) > (Stefan de Konink) > 3. Re: Complete system hangs (likely out of memory) > (Andrew Randrianasulu) The following tool has been instrumental in finding memory leaks and/or peaks of usage in a large graphically intensive program that I have helped another developer with from time to time. https://apps.kde.org/heaptrack/ https://github.com/KDE/heaptrack It comes with text and GUI analyzer tools to allow you to see which functions allocate/release/leak memory during the run of a program and it does not slow down the execution nearly as much as valgrind. It uses a replacement version of malloc and the LD_PRELOAD option to redirect system calls into its own instrumented versions of memory related system calls. Originally written by Millan Wolff in Berlin, it has now become a part of the KDE development environment but it does not require you to run a full KDE desktop. I run in with XFCE on Fedora 36 without any problems. Richard Nolde
