Thank you for the assistance, OT --

Booted into Safe Mode.

Original m4v file would not open -- the "loading" circle with the "pause" button in the center remained active for 20+ minutes with no result.

Also in Safe Mode, I opened Photos and attempted to Export the Slide Show project. Photo crashed on two separate attempts.

Returning to Normal Mode, the m4V file opens but the "jerky" transitions remain using the Classic theme and Sliding Panels music.

Thanks.

The OS X Combo update did provide a noticeable improvement -- however, the transitions between slides in the exported .m4v video are still not as smooth as the transitions in Photo.

Hoping to mask the jerkiness and hesitations of the transitions, I tried increasing the speed selection for the transitions in the Photo slide show prior to exporting. Didn't help much, if at all.

Any other thoughts or suggestions?

On the advice of another Mac-savvy friend, the Activity Monitor was examined during the Export process.

My Activity Monitor shows plenty of workspace while the Photos Export Slideshow is running:

(Trying for the least complex transition) the Dissolve slide transition selection within the Classic theme continued to present hesitations/snags/jerkiness in the exported m4v version.

As I noted at the top of the thread, this malady did not appear when using iPhoto and earlier OS software - even when embedding video as well as jpegs in the slideshows.

Could the current jerky slide transitions indicate a compatibility issue between Photos and OS X El Capitan?
