Repair some TODO from latex source
by Andrea paz 23 Sep '23

23 Sep '23

I made changes in windows.tex to eliminate the second TODO present in the Latex code. I also made other changes and small additions. See if they are okay. The third TODO refers to the creation of a real table from a list. We can see this list in the attached figure. I don't know how to make the table because I don't understand what its contents represent and what it is for. Can someone explain it to me? The section is as follows: https://cinelerra-gg.org/download/CinelerraGG_Manual/User_Folders_Bins.html There is a nice tutorial on this topic (in Spanish): https://www.youtube.com/watch?v=hjrSTjl1-M0&list=PLOnHGAy9DoU1Xaj9HVhBwyov-… And also the text version, whose translation is more convenient: https://andalinux.wordpress.com/2020/12/17/cinelerra-gg-21-ordenar-archivos…

selectable vaapi decoder device
by Andrew Randrianasulu 22 Sep '23

22 Sep '23

Because I have this dual-gpu laptop with intel and radeon (r600) decoding devices I tried to get second (mesa/r600) device going but init failed .. I looked into decoding example: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e and created attached patch now you can select your specific device with env variable: CIN_DRM_DEC=/dev/dri/renderD129 DRI_PRIME=1 LIBVA_DRIVER_NAME=r600 bin/cin in theory same treatment can be applied (with different variable name) to second instance of av_hwdevice_ctx_create (in hw encoder init) but I have no device to test it ...

cin freeze with group move?
by Andrew Randrianasulu 22 Sep '23

22 Sep '23

So, I tried some of the simples group move moves. 1) load 28 sec of media (1 audio/1 video mp4). 2) switch to d&d mode. 3) double-clic on video track where media piece is. It highlight it and add both A and V to group (observe little lines highlighting them) try to drag group somewhere. It usually works one time but not second. dump reads: BC_Signals::dump_stack cin() [0x88b2082] linux-gate.so.1(__kernel_rt_sigreturn+0) [0xf7ec8570] cin() [0x85e6032] cin(_ZN3EDL18delete_edit_labelsEP9ArrayListIP4EditEi+0x43) [0x85e82d3] cin(_ZN7MWindow10move_groupEP3EDLP5Trackdi+0xa9) [0x86b6eb9] cin(_ZN11TrackCanvas9drag_stopEPi+0x3bf) [0x87c708f] cin(_ZN10MWindowGUI9drag_stopEv+0x4f) [0x86c11df] cin(_ZN11TrackCanvas15drag_stop_eventEv+0x1a) [0x87b6f7a] cin(_ZN13BC_WindowBase18dispatch_drag_stopEv+0x683) [0x88d5793] cin(_ZN13BC_WindowBase23dispatch_button_releaseEv+0xb8) [0x88d5968] cin(_ZN13BC_WindowBase14dispatch_eventEv+0x73e) [0x88e0d0e] cin(_ZN13BC_WindowBase10run_windowEv+0x98) [0x88e15b8] cin(_ZN7MWindow3runEv+0x31) [0x86d7be1] cin(main+0x4cf) [0x83bfdef] /lib/libc.so.6(__libc_start_main+0xf9) [0xf5e4d909] cin(_start+0x21) [0x83c7fa1] full dump attached ....

CinGG/NLE comparison
by Andrea paz 20 Sep '23

20 Sep '23

I attach the pdf and odt file to put in the git repository. It is the union of my and Phyllis' writings. It is for new users to compare the workflow they are used to with the one in CinGG. I created the document in odt because it is a work-in-progress that everyone can contribute to. I am not familiar with Adobe Premiere Pro or other NLEs, so I may have written inaccuracies and errors. If you can revise and improve the document, please do me a favor.

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
