export EDL with speed change
Posted by Mathieu Marano on February 21, 2008 at 4:44 pmHi,
I have problems exporting a sequence to EDL. It is a simple 1 track sequence with about 10 clips with speed changes. When I export an EDL, the sequences in/out are or but the clips in/out are wrong. The out is generally off by 20 frames which adds to the next clip and to the next…I am using FCP 5.1.4
Any solution in mind?
thanks

When the EDL was first developed there was no provision for variable speed, such as slow or fast motion (the VTR’s of that time did not have the capability, they only played picture in real time)
so each manufacturer of linear edit gear came up with their own way to remeber the motion effects per edit, usually a note attached to the entry in the EDL. the CMX EDL uses “M2” which I belive is actually expressed as Frames Per Second
example:
M2 001 045.0 01:07:50:21
which means i sped up that shot to 150% or 45 fps
When you load this EDL into a linear edit machine, like a SOny 900 or something antique like that, the edit will be preformed correctly
Where is gets dicey is with an NLE. you see, the Record in is right, the record out is right, and the source in is right. The source out is not the actually time, rather its based on the source tape playing at normale speed.
All that being said, what are you doing with the edl?

The things is not that The Smoke can’t read it, it’s that FCP can’t write the right in/out for the clips te conform on Smoke. When digitizing, there will be some frames missing.

Oh i am sure that Smoke can “read” the edl ie import it as a text file and such
but what may be happening is smoke is deriving the source footage from whats listed in the edl, which is wrong.
the source out time in an EDL event or events with varispeed is ignored by the linear editor. The linear editor uses the source in time, then plays the source at the speed the “speed trigger” or M2 states.
sooooo
when you bring the EDL into a Smoke or other NLE, the NLE will capture based on the Source in and Out, which are not accuratly reflecting the True source in and out for the necessary motion effect
THe best thing to do is to add a lot of “handle” onto the captures, so you will have media to
use. (of course, if your varispeed tricks are slow motion rather than speed ups and you are still missing captured footage then its a different problem) 🙂I know there is a product called Automatic Duck that converts FCP projects to all different project formats, like After Effects. There may be one for Smoke. Its kinda pricey if you are just doing one show, but maybe someone here has a copy and can help you.
Hope this helps
