I was reading the manual "CinelerraGG_manual.pdf" (created March 31 2019) and the manual "CinelerraGG_manual_WIP.pdf" (dated 20190826) by LaTex about Nested Clips. (really good job, guys. And I could print it on the paper in a A5 size) I noticed... - "CinelerraGG_manual.pdf", pg.116, Nested Clips - "CinelerraGG_manual_WIP.pdf", pg.122, Nested Clips The final sentence: "...compositions. They can not be proxied" By my tests/works, you CAN create proxies for Nested clips. Proxies are created in Cinelerra folder (where there is "cin" file) instead of the clip folder as usual (with Cin TAR version. With Package version I don't know). Before saving your project, pay attention to disable Proxy feature. You MUST SAVE your PROJECT with PROXY DISABLED otherwise you lose the link to the clips (more or less). Is it right that proxies are created in Cinelerra folder? Is there any reasons they are not created in the clip folder? Thanks. IgorBeg
