i also found this article, not sure if it already was known? (from 2013)has some grep lines for getting range of images out of Cin's project xml..Believe it or not, that "grep" line still seems to work on an ordinary xml file (that was not even a case mentioned in the article) but that just shows the usefulness of "sed" !
Andrew, if you have the inclination and time, could you look at track.C for why "attach effect" does not work when using In/Out pointers after the June 26, 2020 GIT mods added. Dragging from the Resources window works just fine; "attach effect" on a swiped area works just fine too. This was reported in the forum: https://www.cinelerra-gg.org/forum/help-video/attempting- to-attach-title-to-new-track/# post-1839
I am pretty sure it is just an omission in track.C. Attach Effect works on GIT commit: 48a6854a1ca58aa291ffc6fe3a48807492dfbef7 but fails after commit: 9a75aafbc51be29b49351a51e9084bb34d255c0d
