Hi there, Alberto. Thank you for sharing your workflow, and workarounds.
As for the rendering of effects, I have had some very bad experiences. It seems that when selecting more than one thread, each effect gets a thread, and since some effects apply faster than others sometimes an effect is applied to a frame, or not. -Evert- On 11 September 2017 at 15:09, alberto fuentes <paj...@gmail.com> wrote: > Proxy files are okay to a certain degree, specially early on on the > editing process when bulk editing is done, but they get useless very > soon after a more refine editing needs to be done > > Low quality doesnt allow you to see many details that needs to be seen > in order to edit the small stuff... and even when they do, the proxy > slows down too after 1 or 2 effects are applied, even if less > > Maybe im missing something and i dont know how to use proxy well, but > I have a very new beefy computer and the clip gets choppy very often, > even with proxy files > > Also, switching proxy on and off, invalidates the whole preview... > which makes not wanting to active proxy to begin with > > My solution has been to run preview for the whole clip, even if slow, > its done in the background while editing and while im having my lunch > :) > > Right now the spacer tool doesnt invalidate the preview as per bug > https://bugs.kde.org/show_bug.cgi?id=367079 > > But even if you manually invalidate it, its very slow > https://bugs.kde.org/show_bug.cgi?id=384593 > > > MY WORKAROUND is to watch the whole preview and take notes of the > editing that needs to be done.
