-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Thanx to all, problem solved! Allan Zhang's suggestion made all the difference.
A bit of background, for those interested in TMI: I recorded a presentation on the weekend, and was given a copy of the .pptx presentations so I could follow along on my computer recording the audio and keep the slides in synch (kudos to Kirk Zurell for inspiring me; this is how he recorded Paul Nijjar's "How to Win Electoral Reform" presentation last year). Unfortunately, many of the fancy slide transitions didn't work in LibreOffice; I got lost a couple of times and had to back up (so much for synching with audio); and anyway, recordmydesktop didn't keep up, so there were pixel blocks from earlier slides obscuring the current slide (but the --full-shots parameter might have fixed that). The idea was that the video (recorded separately) and screencap could have been combined in KDEnlive to make a nice integrated video. But since the screencap video is useless, now I'm looking at grabbing each presentation slide as a .png and adding that to KDEnlive as a static image. Unfortunately, slides where the text appears progressively doesn't translate well to .pptx -> .pdf -> .png, but Alex Zhang pointed me to the "Expand Animations" .oxt plugin https://github.com/monperrus/ExpandAnimations/issues It's not perfect (doesn't preserve master slide background colors or gradients), but it creates an intermediate *-expanded.odp file that I can work with. While it means manipulating each .pptx file separately and manually, it does mean that my problem is solved with the application of a bit of manual labour. - --Bob.
