BlueBanana and alpha slider
by Andrew Randrianasulu 01 Apr '24

01 Apr '24

IgorV noticed that alpha slider does not appear to work in bluebanana since ~april 2017 (?) I do not have specific files, I just tried to put jpeg wallpaper on track above video, add BB plugin to track with wallpaper.jpg, and colorpick some color there (so selectin will be visible) sadly moving alpha slider from 100 to 0 in BlueBanana does not have any effect on image in compositor? tried rgba-8, rgba-float, yuva8 (also plain x11 and opengl x11, with and w/o direct method). https://git.cinelerra-gg.org/git/?p=goodguy/history.git;a=history;f=cineler… I do not have pkg from that earlier era, but I'll try to compile sources on earlier system snapshot. Might take some time ...

This looks more interesting than termux, but I guess it takes Android tablets with better hardware: https://vectras.netlify.app/

Question from the forum

An interesting question from the forum: https://www.cinelerra-gg.org/forum/everything-else/how-to-automate-the-cutt… Do you think it is possible to build a script that teaches how to make automatic cuts in CinGG?

removing letter boxing while preserving aspect
by Rob Prowel 08 Mar '24

I have 3:2 content that is saved in a 4:3 frame with black bands at the top and bottom. I want to remove the banding such that the output is a 3:2 resolution clip WITHOUT DISTORTING THE ORIGINAL CONTENT. I've tried playing with the crop filter but the black bands remain, and the camera automation can remove the banding by zooming in, but then the left and right image sides get cropped out of the output. Is there a tutorial for this exact scenario?

ot: intel_pstate

My laptop was making noises under load, and sadly trayfreq was unable to set cpu frequency for some reason. I poked around /sys and found intel_pstate driver can be configured this way: echo 25 > /sys/devices/system/cpu/intel_pstate/max_perf_pct this sets max frequency to 800 mhz instead of 2.5/3.0 ghz as usual. note that 25 is percentage, and on different core iXXX processors results can be different. inxi CPU: dual core Intel Core i5-2450M (-MT MCP-) speed/min/max: 798/800/3100 MHz Kernel: 5.6.14-x64 x86_64 Up: 27d 14m Mem: 2453.5/5887.8 MiB (41.7%) Storage: 610.63 GiB (76.4% used) Procs: 227 Shell: Bash inxi: 3.3.12 I hope this might help Phyllis with her overheating intel laptop .....

Fwd: Chromakey + blur testcase from IgorV

---------- Forwarded message --------- From: Andrew Randrianasulu <randrianasulu(a)gmail.com> Date: Thu, Feb 22, 2024 at 2:19 AM Subject: Chromakey + blur testcase from IgorV To: Phyllis Smith <phylsmith2017(a)gmail.com> oh, it weights 1.4 mb, so not for list ... I think swapping effects relative to cin-cv makes image in compositor more like it was supposed to be but still. even if I disable chromakey - blur behaves strange, like rounding unprocessed (processed as black?) transparency into image ..? ===== https://drive.google.com/file/d/1kqt4bfy53drwQqOvD5RIJ1E7UWeJNF1A/view?usp=… hopefully uploaded to gdrive for everyone to test/see ....

disable a_key in blur.C harder

At this point I am not sure if best course of action to disable it harder or restore it ... but I hope attached patch at least visually restores strange mess we see by default now in test project.

Ghosts from the shell!

IgorV pointed out that while our manual still describes multiple projector keyframes/boxes in compositor it doesn't (reliably?) work this way, namely I think I created second box somehow but can't reproduce :) https://cinelerra-gg.org/download/CinelerraGG_Manual/Compositor_Keyframes.h… "Move the projector slightly in the compositor window to create a keyframe. Then go forward several seconds. Move the projector a long distance to create another keyframe and emphasize motion. This creates a second projector box in the compositor, with a line joining the two boxes. The joining line is the motion path. If you create more keyframes, more boxes are created. Once all the desired keyframes are created, disable automatic keyframe mode." small video describing how it worked in cinelerra-cv 1.2.1 using old dynebolic 1.4 iso https://m.youtube.com/watch?v=08UCImr82CE I wonder how "long" must be long distance? offscreen? tried this, also with enlarged projector range .... no two boxes! I can't even see this behavior in cincv 2.3.* from 2017, but may be I am doing it wrong for all versions?
