hey, Trevor,
nice to meed a fellow Macro user!
you need to get the clip to open into the Viewer widow,
from there, you can open up the Modify > Timecode window.
you’ll need to assigns Modify > Timecode a shortcut.
in the Customise Keyboard window this command is (slightly confusingly) just called “Timecode”
once you get that window open you DO need to program a mouse click on the “Source Reel” check-box
otherwise the Reel field is non-enterable.
if this is not possible with Butler, or if you prefer to work with Keystrokes only (i do with QuicKeys)
then you should PRE-ENTER a bogus reel# into all your clips that don’t have one.
do this by sorting the clips i the Browser by reel. (or maybe using the search tool in the browser?)
find al the clips with no reel.
enter you bogus reel name (such as NO REEL) to one clip,
then right click in the reel column for all the others and choose the new NO REEL name.
if you do this, then the Reel field will be accessible in the Modify > Timecode window.
you need to Shift Tab back to it from the TC feld.
cheers,
nick
