The one thing FCP X has over PP CC is that it has many more included effects/transitions, basic things even like star wipes and circular wipes - CC doesn't seem to have a lot of that - does anyone know where to get free plugins from ?
Probably right now they are - i'd love the Juicer FX (so many good transitions) - but I'm just looking for the real basic ones that should be a part of any NLE ! Admittedly they don't come into play a lot in my projects (mostly episodic TV) but it'd be nice to have
Most of the ones you will use regularly are there and can be edited if you wish. The others such as you mention are not considered relevant to an app like Premiere as they are probably not used by the vast majority of pro editors.
With respect to editing, less is more and the basic transitions are still fades/dissolves.
I am not one for really usesing much transitions But I Have agree , Adobe transitions are very lacking and have be come very long in the tooth there some free transitions and effects which you can find that worked on 5.5 and 6 http://www.studio1productions.com/Articles/CinemaFX.htm and look at this http://www.lafcpug.org/phorum/read.php?20,279074,279074
Here's a list. I have no idea if any are free.
To create a custom effect, I usually start with a preset that is simiilar to the effect I want, apply it to the clip, change/customise as you want, then in the Effect Controls window right-click (Windows) on the Effect and you will see an option to "Save Preset". It will then show up under Presets at the top of the list.
Periodically it is a good idea to back up the presets (as it is any of the settings because the new Sync to Cloud doesn't seem all that reliable or does it even back these up, IDK) by clicking on the panel menu and selecting "Export" option.
I agree with you. Please make feature requests for new effects: http://www.adobe.com/go/wish
If you are on PC, there are more stock effects over Mac. However, there are some third party effects for Mac that don't run on PC, like FX Factory.
