Description Barade 2018-09-30 12:26:02 UTC
SUMMARY
When I have a title clip on my track and add the effect "Fade to black" it works perfectly.
The fade takes 1 second.
If I stretch the title clip on the track now, the "Fade to black" becomes invalid.
It seems to fade to black too early (at the same position as before) and therefore I have to delete the effect and readd it to make it work again.

STEPS TO REPRODUCE
1. 
2. 
3. 

OBSERVED RESULT


EXPECTED RESULT
Stretching the title clip on the video track should keep the fade to black effect at the end of the clip.

SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version:

Please try with the actual Kdenlive AppImage version 18.08.2
Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage

Hi,
I'm sad to say that this very annoying bug is back again!
I'm using 19.08.0 on the last KDE neon, all updates installed.

This bug was fixed before (see #363538) and has reappeared recently.

Please fix this and thank you for your incredible work on this awesome software.
Comment 3 emohr 2019-08-31 12:36:40 UTC
Tested with 19.08.0 on Windows and Linux (AppImage). Fade to black keeps the lenght when stretching the clip. 

Please try with the current Kdenlive AppImage version 19.08.0a to see if there are any packaging issues https://files.kde.org/kdenlive/release/ 

If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.

test project with fade out bug

Hi,
I have made new tests and indeed, the bug does not occurs on a new project.
But if you could look at the attachment, a very simple project, you can see that the bug is still there.

It's a 2011 project I created with kdenlive 0.8.2.1.
Then I tried to open it with kdenlive 19.08.0 but kdenlive crashed every time I tried to open it. So I migrated to kdenlive 16.04 then to 19.08.
Now I am currently on 19.08.1 the latest build on KDE neon.

Steps to reproduce:
1. Play it: every fade to black fails
2. Reduce a clip under 6 seconds: fade to black works

Sorry I didn't tried with the last appimage.
I spent many hours in this project (attachment is a minimal reduction version) and I want to work again on it, but the bug is still there.

Thanks again for your work. Still considering kdenlive as the best :)

Confirmed. Are the titles made in kdenlive 0.8.2.1? With new titles created in 19.08.1 fade to black works.
Comment 7 pruje 2019-09-19 08:56:48 UTC
Yes, titles were created on 0.8.2.1
Comment 8 emohr 2021-02-28 16:28:02 UTC
Your test project with the 2 titles is working correctly with version 20.12.2.

Feel free to reopen this bug or create a new report if this is still happening with the latest version (https://kdenlive.org/en/download/)
