Re: [CinCV] Multicam editing

Hi Raffa!

I don't think JACK will be terribly useful here as it is only supported by
LiVES which is lacking in compositing features, all the rest of the Linux
NLE's don't support JACK (yet). Xjadeo is a video player that uses JACK
and will sync with JACK transport, I don't know if you can run multiple
instances of Xjadeo to a common output though...

I'm a little lost with answers for the actual compositing, I do know that
Openshot can quite easily route 4 distinct Video tracks to one screen by
mapping them each display in 1/4 of the screen, but I think you are
talking about something other than that.

One thing I do know is that recent GIT builds of Kdenlive 0.9.3 have a
great audio alignment feature for exactly the kind of thing you are
talking about. I used it for a music video recently and you simply select
one track to be the audio reference and you select the other tracks to
align themselves with the 'reference' track and it works great and saves a
huge amount of synchronizing headaches. I am pretty new to Kdenlive and
I'm not terribly sure what the compositing options are with MLT (it's
underlying framework.)

For Ubuntu users there is a Kdenlive-SVN PPA here:
https://launchpad.net/~sunab/+archive/kdenlive-svn

Good luck with your project, I'd love to see it when it's finished!

Take Care, -GLEN

[CinCV] Multicam editing

2012-11-10 Thread Raffaella Traniello 

Ciao!

I have the task of editing a video of an event taken with 4 cameras.

Synch is going to be easy (long files, with clapboard) and I'll load 
every camera file on a dedicated track.


Now I dream to have 5 compositors, a big one on a screen for the 
timeline output and several small ones one for each track on another 
screen so that I can feel like if I had a video mixer and I could 
preview all the tracks simultaneously.


I know Cinelerra can't do that.

Do you know any other FLOSS program that can do that?

Can I set a video player to playback several files at the same time with 
centralized play/stop?

Can jack be of any help?

Thanks in advance for any suggestion.

Ciao!
Raffaella

I'm always open to discussion. I'm not even that versed in graphics
processing, so I appreciate the clarifications.

I found [1], where even the Intel engineers are not quite convinced one
way or another, except that the operations should be vectorized for use
with SSE if at all possible.

BTW, I like the 0=Black/1=White choice. I suppose that the original foot/
headspace came from analog tolerances?
