does the frame rate affect this.
An earlier reply noted a rounding error in cinelerra.
I don't notice any flickers, but I operate at 25 fps (PAL). Is 30fps
really 29.97, which might cause this?
Both tests (see previous answer) will occur tonight (in 7 hours) and
results will be posted.
Thank you for your answer.
Tests done.
I tested at 15, 25, 29.97 and 30 fps.
Nothing better... still flickering.
What happens if you manually move your second keyframe a bit to the
left, causing the progression of the blur amount to stop a bit earlier,
not at the end? What happens with the flicker *after* that second
keyframe
- does it continue to flicker?
- does it just stay there blurred and otherwise static?

I tried what you proposed :
- Track during 10 seconds, still picture, blur effect on the whole
duration
- first keyframe at 0 second, with radius = 0
- second keyframe at 5 seconds, with radius = 30
- rendering...
- flickering happens from 0 to 5 seconds. 5 last seconds shows a still
blurred image.
I tried to play with other effects, but I'm not sure about the results.
Blur does produced this buggy result.
May someone else confirm?
Hi I tried your test and put my result on youtube, but I don't see any
buggy result.
the image shows the release version and the frame rate was 30fps
