split video file into pieces using EDL

[Steven Gonzales]

I would just use Final Cut, but you might be able to use applescript to accomplish this if you have quicktime pro.

The applescript dictionary for Quicktime includes:

select?v : Select a range of time
select reference : the movie whose selection is to be set
[at integer] : starting time of the selection
[to integer] : end time of the selection

and

trim?v : Remove all content before and after the current selection
trim reference : movie

and

export?v : Export a movie or track to a file
export reference : the movie or track to export
to file : the destination file
as AIFF/AVI/BMP/DV stream/Fast Start QTVR Movie/FLC/hinted movie/image sequence/interframe compressed VR object movie/iTunes/MuLaw/MPEG2/MPEG4/picture/QuickTime media link/QuickTime movie/QuickTime TeXML/standard MIDI/System 7 sound/text file/ThreeGPP/wave : the desired file type
[using default settings/most recent settings] : the export settings to use
[using settings preset string] : the name of the export settings preset to use
[using settings file] : the file containing the export settings
[replacing boolean] : should the original file be deleted first?

Here’s a collection of quicktime scripts that you might be able to adapt:

I’m not sure how applescript handles time. Time is an integer, so some conversion will have to take place of your timecode numbers.

I think time is explained in the Quicktime Movie Internals Guide:

I found a couple scripts to deal with timecode conversions at https://bbs.applescript.net/viewtopic.php?id=22304

******QuickTime time -> SMTPE:

Open this Scriplet in your Editor:
property TimeOffset : 10

tell application “QuickTime Player”
tell document 1 to set {currentTime, timeScale, theDuration, FrameCount} to {current time, time scale, duration, count (frames of track “Video track”)}
end tell

set FrameRate to (FrameCount * timeScale) / theDuration div 1
tell (currentTime / timeScale) to set {hr, mn, sc} to {it div 3600, it mod 3600 div 60, it mod 3600 mod 60 div 1}
set fr to (currentTime mod timeScale div (timeScale / FrameRate))
set SMPTE to addZero(TimeOffset + hr) & “:” & addZero(mn) & “:” & addZero(sc) & “:” & addZero(fr)
display dialog “TCR ” & SMPTE

on addZero(v)
return text -2 thru -1 of (“0” & v)
end addZero

*****SMTPE –> QuickTime time:

Open this Scriplet in your Editor:
property TimeOffset : 10
set SMTPE to “10:20:24:20”

set {hr, mn, sc, fr} to words of SMTPE
tell application “QuickTime Player”
tell document 1 to set {timeScale, theDuration, FrameCount} to {time scale, duration, count (frames of track “Video track”)}
end tell
set FrameRate to (FrameCount * timeScale) / theDuration div 1
set QT_time to ((((hr as integer) – TimeOffset) * 3600 + mn * 60 + sc) * FrameRate + fr) * (timeScale / FrameRate)

i’d do it manually in FCP;

import the EDL, and you’ll get a sequence of off-line clips
line your movie up against that in a sequence,
select al,
then step thu and add markers to it
down arrow = next edit
m to add a marker.

drag your marked up clip into the browser,
toggle it open,
select all the markers and dag them into a new bin.
they will now be sub-clips called “marker 1”, “marker 2” etc
then you can batch export
and use a batch re-namer to tidy up the names on the new files.

but it;s late and i might be missing some really obvious simpler way to do this.

cheers
