If you apply the efx to a clip in the TL, then go File>Save video EFX preset, it gives you the category (Custom, or new category>Favorites) to save it into.
then that folder is in the EFX browser. Unlike the save preset in color board where you have to select one preset after you have applied the color efx.
No keystroke but customizable.

carry on…

I’ve been doing a lot of miniDV tapes just lately, and have not found any of them to look bad: some are old and dropouty, and the frame size of the SD ones is small. Make sure your monitor is set to view 100% or they really degrade! I’ve been dropping them into a 720p timeline, and it looks good this way, even stretched to fit.

Well, you can’t. But you can use the skimmer to quickly select each clip and hit F for Favorite. Then with the Browser in List view, all those Favorites will be listed. rename each of them–easiest to do right when you create them. They act and look kind of like subclips (which they are, of course) but without the subclip limits.

Wow. FCP v5? Is that the project you used 7toX on? Or did you have a v7 version? I would not expect things to work from 5 to X. Why not relink all the clips manually? I have done this with old (v7) projects that never have seemed to come in perfectly from XML. (It is probably a metadata issue, (IMHO). I have some clips in a new project that whenever i send an XML out to v7 (Xto7), are never found and have to be relinked).
the clips are not really ‘missing’, FCP just needs to be told where they are.

Not quite the end of the discussion, IMHO.
I have been working on a feature doc with FCPX since March 2012, and developed some ignorant workflows. One of which seemed brilliant at the time, was to cut each ‘scene’ as a CC using the selects, so I did not have to go back hunting thru the Browser.
Now at the end, cleaning up, I was deleting all those CCs in the Browser (they have been very useful), but some of them gave a warning that they were being used. I didn’t think so, but left those alone. As a test, I deleted one with that warning and sure enough, that scene, broken apart, reedited often, in a project which has been duplicated/versioned multiple times, showed up with missing media. Not every shot, because I think when I put in a new cutaway or VO shot they were clear of the CC. But most of the scene had missing media. I reproduced the cut easily enough, but I don’t know how to finally and fully break the connection between the CC and the project. Certainly Shift-CMD-G doesn’t do it.
