[kdenlive] Best workflow for large projects

[Pascal Fleury]

Hi Simon,

I am just finishing such a project, with a few (~15) video files from 2
cameras, each file in the 2GB range.

My workflow is this, and it assumes that you will watch the whole thing at
least once fully:
1- import the videos in full as clips into a project
2- optional: if playback is a bit slow, then switch on proxy clips, and
wait for them to be computed.
3- I then prepare a video track called "stock", and watch the clips.
While it's playing I use keys to set in- and out-points. When I press
'out', the clip is dragged to the timeline (just drag the clip monitor view
to the timeline, it will add a clip taken between the current in and out
points). [see this
<https://kdenlive.org/user-manual/quickstart-guide/first-project/dragging-clips-timeline>
]
Once the clip is in the timeline, set the current position to 'in' again,
and press play. If I want to skip material, I just wait until I get to the
end of junk, then press 'in' again.

At that point, I'm not worried too much about exact frame cuts, I merely
want to strip off the material I will not use (I had one camera in hand,
and I did not stop it even while walking around the public at the event, so
I filmed a lot my feet...)
You will end up with a chronological set of clips on the timeline, which
you can then further edit, reshuffle, and push together if you did not do
it yet when adding them to the timeline.

I am using Kubuntu 13.04 (I know, should be updated...), kdenlive 0.9.8 and
have a ShuttlePro-2
<http://ergo.contour-design.com/ergonomic-mouse/shuttlepro-v2> so I am
actually not sure about the keyboard shortcuts, but I know they exist or
can be configured.
