Pancake editing
by Andrea paz 12 Sep '23

12 Sep '23

Also from the YouTube channel "Film Editing Pro" is an overview of 3 editing methods: 1- three points editing (Two Screen Editing, in CinGG) 2- Timeline editing (Cut and Paste + Drag and Drp, in CinGG) 3- Pancake (stacked) editing See: https://www.youtube.com/watch?v=Tsohm9SE9Mk Panckake editing start at 3:31 Only Premiere Pro has pancake editing functionality [Note: actually Lighworks and even DaVinci Resolve have this functionality]. PP indeed allows you to open multiple timelines, place them on top of each other in a stack, and operate between clips of these with Drag and Drop. One feature of pancake editing is the ability to see a timeline on the Source Monitor (our Viewer window); thus one timeline is seen on one monitor and the other on the other monitor (The classic Program Monitor -Compositor window, in CinGG). In fact, it would be difficult to do editing without seeing the contents of the clips on the monitor. In CinGG, in my opinion, we can do a workaround that simulates pancake editing even though it is not quite the same. Just open multiple instances of CinGG, bring the program windows of all instances closer together, and operate between timelines not with Drag and Drop but with Cut and Paste. We can't display a timeline in the Viewer window, but we don't need to since each instance's timeline carries its own Compositor window where to see the contents of the edits. I am convinced that opening multiple instances of CinGG is no more heavy than opening multiple timelines in PP. What are your thoughts on this?

Timeline x Hollywood

To make up for my recent mistake (timeline = canvas), I offer a curious video on what a timeline looks like for large professional projects. However, their entire YouTube channel is interesting and informative. https://www.youtube.com/watch?v=oWXqYd-OhaA

Still on hardware acceleration
by Andrea paz 05 Sep '23

05 Sep '23

@Andrew Sorry to bother you again on a subject you have already tried to explain over and over again. Reading this page: https://trac.ffmpeg.org/wiki/HWAccelIntro it is my understanding that when decoding (note: from here on I am only referring to decoding/playback!) you can use the "-hwaccel" option without any other settings. If the media file used supports hardware acceleration, then it will be used automatically without anything else to do. If it is not supported it will automatically switch to software decoding. There is no need to specify the device (because a device is automatically selected, even if it is not the preferred one), so it would be a generic feature that decides for itself when to run. Question, how can I impose "-hwaccel" when compiling CinGG? Another thing concerns decoding with Vulkan. Again, these are generic instructions and I would like to test it, however it requires device initialization, to be declared explicitly (although a generic term is fine: "vulkan=vk:0") and a few other options. See here: https://trac.ffmpeg.org/wiki/HWAccelIntro#Vulkan The question is always the same: How can I compile vulkan in CinGG to do some tests?

Monthly AppImage updates
by Phyllis Smith 05 Sep '23

05 Sep '23

April 30th AppImages are now available with the binary only updated with X264 r3106 stable mods. But, I have a problem with being able to update the GIT repository on the server due to some error I made which I am now working on. Release Notes Update below: *********************************** GIT for Cinelerra-GG has the following changes from 04/01/2023-04/30/2023 *Server Maintenance work has been done by Sam* on an ongoing basis along with the difficult task of accommodating newer requirements by Google Gmail. Changes to the Mailing List settings for compliance was very time-consuming and much appreciation goes to Sam for continuing to volunteer his time for critical needs. *X264 *has been upgraded to r3106 stable release. There appears to be no X265 stable updates. *Clang-16* related modifications in thirdparty/Makefile, libuuid-1.0.3, and mpeg2enc.c to support new termux distro have been contributed by *Andrew*. *Prores_ks *render format has had the Apple writing library added as the default with ffmpeg since that is who created this specific prores format. This should make the rendered video more compatible with other software products. Mod provided by *Andrea*.

https://youtu.be/URnvDY7Zjic at least cin does this on my 32-bit-on-64-bit kernel system ... recorded by another instance of the same cin version. Note, my machine set to full 3.97 Ghz speed. Also, I have 4 frames per bg job setting

fileexr reading error handling

31 Aug '23

Using https://openexr.com/en/latest/HelloWorld.html as example so for now I have base commit d51dc1ff2dbd920c6488af4380b8064c9b6a7b4c (origin/master, origin/HEAD) Author: Good Guy <good1.2guy(a)gmail.com> Date: Tue Aug 29 20:20:10 2023 -0600 Credit Andrew - rest of fix for Arch (and termux) which includes thirdparty/Makefile plus commit afa6a601fd3228be18aef413061b3d0165344d7c (HEAD -> master) Author: Andrew Randrianasulu <randrianasulu(a)gmail.com> Date: Wed Aug 30 07:27:57 2023 +0300 Fileext reading error handling for bg render commit cac447973db936f7d5594c83521c34f3e5a9c187 Author: Andrew Randrianasulu <randrianasulu(a)gmail.com> Date: Wed Aug 30 05:27:10 2023 +0300 Add libjpeg dep to.libtiff in thirdparty/Makefile commit 8297b38e49da0ce73e119138c158e806eb1fb45d Author: Andrew Randrianasulu <randrianasulu(a)gmail.com> Date: Wed Aug 30 02:48:47 2023 +0300 Possible fix for ffmpeg 4.4 in pluginfclient.C ==== so, ffmpeg 5.1 based cin seems to work on Slackware 15.0 i586 (with some self-build packages). Tested adding ffmpeg video filter to video track, and of course background render with on-the-fly compressor switch. aggrh, in commit message fileert instead of fileexr. I hope this is not a big problem will try my virtual machines next

OT: comments from youtube can be saved, too
by Andrew Randrianasulu 31 Aug '23

31 Aug '23

I stumbled upon video with 6K comments and opening them all one by one was too much work, so I looked if there was way to automate it Apparently yes! ytdlp_nest_comments.py -i file.info.json -o output.html and json produced by yt-dlp --write-comments https://gist.github.com/pukkandan/ee737fec64822f2552caf3ca4cbf5db7/raw/5ace… after this you can search in there .... I also noticed cinelerra-gg was typed-away as cinelerra-ng , Main complain apparently yes, lack of easy "clip" like synchro on timeline, but then with more clip-like timeline you usually need separate operation for "disconnecting" audio from video if need arise? I can only guess a/v sync problems were bigger back in analog capture days, so Broadcast2000/Cinelerra were coded with track paradigm instead of clip paradigm. This specific author comes under handle "Reluctant anarchist", not sure how serious he is about it, but for me anarchism is about, well, citizens who can do things without being bossed around, including repairs, including on software tools. But because everything is embedded in "money rule" world of today ..it really very uphill battle, from both "ghost of the past" problems like Windows dominance to very mindset of even nominally open-source programmers caught in endless update cycle. And even "unimportant video firmware issue" may lead to such oopsies as https://gitlab.freedesktop.org/mesa/mesa/-/issues/?label_name%5B%5D=VA-API https://gitlab.freedesktop.org/rdong/mesa-rdong-2021/-/commit/de95ff3a3dcb4… I mean, if video firmware was open AND there were outside developers understanding how to mod it those bitstream errors probably can be corrected on GPU side ..it all in _firmware_ exactly for greater flexibility and bug-fixability! But because h264 is patented It seems unlikely AMD will be able to open this part of their driver, let alone train libre software engineers on how to mod it .... and there is no active reverse-engineering project about this because .... video considered niche and ppl just buy bigger/newer CPU usually (even I bought new GF710 gpu because integrated Radeon3000 was hanging on object move in Blender 3.3! too big shader!) * - there was essay/opinion piece on osnews how Microsoft apparently forced PC dealers/vendors back in 1990x to NOT install anything but Windows. Today Microsoft developers work on mesa3d, but this unfortunately doesn't change world context ... https://www.osnews.com/story/136392/the-only-pc-ever-shipped-with-beos-prei…
