editing process when bulk editing is done, but they get useless very<br>
soon after a more refine editing needs to be done<br>
<br>
Low quality doesnt allow you to see many details that needs to be seen<br>
in order to edit the small stuff... and even when they do, the proxy<br>
slows down too after 1 or 2 effects are applied, even if less<br>
<br>
Maybe im missing something and i dont know how to use proxy well, but<br>
I have a very new beefy computer and the clip gets choppy very often,<br>
even with proxy files<br>
<br>
Also, switching proxy on and off, invalidates the whole preview...<br>
which makes not wanting to active proxy to begin with<br>
<br>
My solution has been to run preview for the whole clip, even if slow,<br>
its done in the background while editing and while im having my lunch<br>
:)<br>
<br>
Right now the spacer tool doesnt invalidate the preview as per bug<br>

<br>
But even if you manually invalidate it, its very slow<br>

<br>
<br>
MY WORKAROUND is to watch the whole preview and take notes of the<br>
editing that needs to be done. Then, start working on those points<br>
FROM THE END TO THE BEGINING. This way, the spacer tool and moving<br>
things around, wont invalidate previews clips<br>
<br>
If you start from begning to end, every little edit that involves<br>
spacing or insert, will invalidate the whole thing<br>
<br>
<br>
<br>
Id like comments on this idea, and hows your own workflow in kdenlive,<br>
because im new to video editing in general and kdenlive in particual,<br>
and maybe im doing something wrong<br>
<br>
Thanks for reading!<br>
<br>
<br>
PS: Also, is it possible to use several threads for preview? I have a<br>
modern i7 with 8 cores and only 1 seems to be working. Since 1 second<br>
chunks are procesed, this seems an easy target for parallelization,<br>
unless last frame preview is needed for the next and I dont know about<br>
it. Not sure if I should open a bug about this or if this new timeline<br>
that is being worked on right now will fix all these problems. A<br>
developer comment would be welcomed :)<br>
