Hi Georgy, Phillis and the team! Here's how my tentative with the shaker2.xml and the video went: https://croatiafidelis.hr/foss/cap/cap-220925-cinelerra/pg-220926-motion.php The files necessary are there (as I got them in email that missed to be sent to Cin ML). Why it did not produce the expected result? (I haven't examined the XML-after yet, but it's available on the page.) And I can also try and see if I can do better with the files at: https://www.cinelerra-gg.org/media/demos/stabilize/ Regards! -- Miroslav Rovis Zagreb, Croatia https://www.CroatiaFidelis.hr my PGP-key: https://www.croatiafidelis.hr/FCF13245ED247DCE443855B7EA9884884FBAF0AE.asc
