I woild just send the aaf from the timeline as is. There is no need to strip any effects off per say. If there is an effect they don’t have, it will come up on their end as an “unknown effect”, which will force them to find out (from the reference movie with tc burn you are also sending) what is happening at that section. The underlying clip will still be there.
As for an edl, i don’t use them too much anymore. There are lots of new templates that will allow way more audio and video tracks than what we used to be limited to, but same thing, i would just send an edl. Pretty sure when it encounters something it doesn’t understand, it will just move through to the next item.
One key would be to ensure you commit any multicam edits before making your lists. If you use multicam, and you don’t do this, the list will be trash on the other end.
