Bug ID: 367984
Summary: Clip Speed effect is lost after moving clips with
speed fx applied, saving project, closing and opening
it again
Product: kdenlive
Version: 16.08.0
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: critical
Priority: NOR
Component: Effects & Transitions
Assignee: vpi...@kde.org
Reporter: oo...@o2.pl
I love KDENLIVE, Yet there are some very basic problems that persist through
about 4 yeard, that i'm using it. it makes a lot of pain and going around
problems that shouldn't exist at a such od advanced stage of this project,
that's why i decided to start contributing in this way as of right now:
My suggestions that are regarding this problem, and as well those that exist
ever since i can remember this project - at least 5 years:
1. Timeline structure/ the way that clips are being positioned and
saved/remembered on timeline - every change in any way is messing up all clips
positions, fx's applied, lengths etc.. I think the change is absolutely needed.
No other NLE's have such root/basic problems when switching between different
framerates, and loosing clips/fx's positions without any reason, like this bug
that i am filling..
A simple saving and opening of project can loose all effects that are applied
to clips.
right now i MUST create /save a new project every 15/30 minutes of editing so
when at one point without any specific reason it will loose all / or any
effects or cuts applied to clips - i can somehow recover and recreate work
already done.
PLEASE Consider this if you ever want thins project succeed as much as i would
want - whether in Windows environment, or in linux world.. it simply CANNOT be
freezing, and loosing these most basic points. - HOW do other champs like sony
vegas or whoever for this case do it? premiere, edius.. they'v got it down for
at least 10 years..
Maybe switch to some absolute hook/ scalable/ vector/ quantifier based system
for all events, and correlation system to connect fx/to specific clip as
well(?),
so regardless of framerate and such it would keep precise points .. and
conversions would be possible as well without loosing ALL Edits, cuts, fx's,
fades, etc..
I believe it would be a REVOLUTIONARY Step, that could fix maybe even up to 30%
of all bugs related to timeline/fx's problems?
2. Unable to apply speed to reverse clip.. it messes up clip and creates a thin
line out of whole clip, that is unworkable.
now i reverse clip - render it out - put it on a time line and apply speed fx.
- this problem also exists for a long time
3.Edit mode on a single timeline like in sony vegas - that you can overlaps
clips and set crossfade point of clip a and b - it makes it quite faster and
nicer to use.
4.Playback speed - possibility of setting playback speed so there would be no
lost frames - even with older machines, and on full quality - 3/4 speed, 1/2,
and 1/4th should be sufficient.
5.Playback Quality - it appeared in 16.08 - which is nice - draft/ and HQ -
however i do not see a big difference cpu usage is still high, and i get jerky
playback/not smooth
I have an i7 processor and material is canon fullhd mov file It is not smooth
regardless of whether i have 2 cores, or 8 cores, and it shouldn't be like that
In premiere/vegas it is easy to make smooth playback even in 1/4 or 1/8th
original quality - and do full edit on laptop - and set it to render on
stationary machine.
Especially in a era of 4k and 8k RAW source clips.. that you already are
preparing /ready for-which is great- .
This option will be a VERY Important to be able to choose even 1/16 of original
resolution - which will be enough for editing on a low end laptop - and than
move it to Fully blown NLE Hardware..
6. if you have any recommendation/ combinantion of distro/ that is most stable
and those problems do not apply / exist - please do put it up on MAIN WEb site
as recommended , and put PRECISELY EACH Component, repository, number, and
such, so people will have a smooth ride and not get discouraged.
7. some way of donating/ fund raising to speed up of solving most important
problems.
many people have money, but do not have skills, nor time to personally help -
then it should be PRIORI Visible on main page. ABSOLUTELY. I'd rather pay
50$/or 100 to fix those problems/implement to kdenlive, than spend it on sony
vegas..
All of the best to THE Team!!, and project!>
Cheers!
Reproducible: Always
Steps to Reproduce:
1.put clips to bin
2.moove them to timeline
3.apply speed to clips on timeline
4.make come cuts, adjustments like in point, out point fade in out.
5.move clips around
6. save project, close
7.open project
8 move clips around, save, close project
9.open project - speed effect will be "gone" - either physically from clip
effects stack, orit will be there, value will be as set, only it will not be
"in effect".
However clip sizes/lengths - visual blocks on timeline will be correct, but
speed and length of clip will be not correct.
10 if you go to fx stack for specific clip - choose value of speed and add 1
poin, or substract from any given value, like 237% - change to 236% - the
visual length of clip will abruptly/suddenly change - on a timeline - and fx
for that one clip you'd change value will work, but the rest you'd need to do
the same.
11. than you must set out point for specific clip /or stretch by clicking and
dragginh right edge of clip it to previous correct length - which would be
typically marked by next clip's beginning.
Actual Results:
problem appeared, speed fx not working.
and got partially corrected by doing the extra steps provided above / redoing
the settings
Expected Results:
Just exactly what it should. Play clip, on a timeline, at specific in and out
point, specific speed, not loose settings after a simple save close and open
project.
As suggested i feel that timeline system is causing all of those and other
problems.
Also those few wishes/wishlist or rather suggested fixes for problem could be
a major improvement/ step forward before going to windows platform for whole
project/community.
Maybe there would be a way to somehow use ready modules from other linux
projects like lightworks, or shotcut?
Please feel free to contact me about anything.
I Believe in KDENLIVE To be the best and most versatile project for NLEditors
I am willing to help out, provide more info, and test it out/ other solutions
to find a true cause / a possible solution, or to set guidelines / unification
to higher standards for this project, and improve User Experience
.., or even pay to get those fixed/ get functions implemented / applied! :-)
