[ubuntu-studio-users] Cinelerra-GG

[Mike Squires]

I'm trying to build a toolkit to create videos of musicians playing 
together as in the Chad LB video of Coltrane's "Giant Steps", but using 
open source tools.  I would like to do this in the Ubuntu Studio 
environment rather than just installing AVLinux.

I've done a little, including a video that merged a video track shot 
with a smartphone with an audio track recorded using a Zoom H4 using 
OpenShot; it worked well.  However, OpenShot can't as far as I know 
allow the windowing of video streams as the audio content changes and I 
don't see that in KDEenlive either.

One package that I have a little experience with is Cinelerra.  I had 
previously played with Cinelerra-CV but it appears that this project has 
been merged with Cinelerra-GG.

An attempt to install Cinelerra-GG from the cinelerra-gg.org web site 
failed.  There are instructions to install onto 18.04 but the directory 
did not exist.  I assume that the project has newer files under 
development, but I don't really know that.

On a chance I ran the code that downloaded the current cinelerra5 source 
code from the "git" archive which worked.  Much to my surprise, given 
the complexity of the package, configuration, compilation, and 
installation of cinelerra-gg succeeded using the instructions for a 
"shared BUILD" in the README found in the root directory of the source 
distribution.  One warning:  the compilation ran all 8 cores of my dual 
quad Xeon at 100% for quite a while, although other applications could 
be run at the same time they were definitely slowed down.

It configured, compiled, and installed.  Execution from a launcher also 
worked.  I've only read in a .MOV file that I'd already created and 
played it, and that also worked.

I'm quite a bit out of my depth as a programmer here, but I've been 
compiling and installing things on my FreeBSD systems for years and 
following that path seems to be working OK.

The path used by others has been to send out a click track with charts 
for the rhythm section.  Once the rhythm section audio is merged it is 
then send to the section leaders, if any and the result of that process 
is merged and then sent to the section members.  The result of this 
process is then sent to the soloists and the final merge of audio tracks 
and video tracks is then done on something like Cinelerra.  The 
individual recordings can be done as simply as shooting video from a 
smartphone but a separate recording on better equipment is of course a 
good idea.
