Bug ID: 403320
Summary: "play zone" -- preview without effects
Product: kdenlive
Version: 18.12.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: j...@cspv.hu
Target Milestone: ---
SUMMARY
it would be great if we could preview a "zone" of a video without the effects…
(explanation* below)
if effects, "all" or "costly only" could be temporarily turned off, it would
not only be great for those who only have slow machines.. but for all who want
to collaborate with others or/and port projects from one computer to another
one...
to view a segment of a video without the effects is totally informative cause
the rhythm of the video is almost a separate thing from what the clips actually
look like... I would say, it is two different "layers" of the editing, two
different aspects… so, it would be great (if not super great) if effects could
be turned off temporarily during previews…
STEPS TO REPRODUCE
1. play a zone with lots of effects on each clip on a slow machine
2.
3.
OBSERVED RESULT
it is jerky, some short clips might be skipped altogether
EXPECTED RESULT
it could be played "without ALL effects" or "without costly effects", or
without "all audio" effects or "without all video" effects…
there could be a “effects during preview” dropdown option menu or something, up
in the main toolbar, next to the render button… for example…

* EXPLANATION:
→ as you know, in some cases, people work on slower computers…
however, thanks to KDENLIVE's portability, it is also possible that now you
work on your slower machine, now you're back on your fast machine…
→ in many cases, without the effects a slow computer can handle yielding a
pretty decent preview…
→ to turn off effects one by one is not an option, for more than one reason
(one of these: not all effects are turned on all the time on a given clip)
→ using proxy clips is not a good enough option either…
cause creating low-res copies of all videos takes too much...
and when you open the project on your fast machine, again, you need to change
back to the hi-res video files...
