The same here in VP18
In VP 17 I don't see any "grips" - but I have to say that I had never used it with this accuracy.

@walter-i. Thanks for your reproducing. This feature is critical for advanced animation.

Ich habe es nochmals getestet - es funktioniert schon, man muss auch den vorherigen Punkt "manuell einzeln anpassen"
Translate:
I tested it again - it already works, you also have to "manually adjust individually" the previous point

It seems you misunderstand the op's meaning. @walter-i. Try to watch the difference among the three.

Yep 😂

This bug is a problem left over by history since sony.

@NickHopeTestAccount @NickHope Hey bro, look at this. This should be logged in known issue. 😟

"This should be logged in known issue."

This already was/is logged.

Done.

[VP≤13+] Interpolation of an FX keyframe can only be adjusted manually using the spline curve handle to the left of the keyframe if the preceding keyframe is also set to "Manual" or "Split Manual".

I imagine it might be quite difficult to change that behaviour, because the shape of the curve between keyframe is controlled by the previous keyframe's setting. If it's not set to "Manual" or "Split Manual" then it kind of makes sense that it can't be adjusted by the later keyframe.

I guess it could be addressed by one of these:

1. Automatically setting the previous keyframe to "Manual" or "Split Manual" if the user tries to adjust the handle on the left.
2. Simply don't display the handle on the left unless it is able to do something.
3. Open an explanatory notification window if the user tries to adjust a handle that cannot do anything.

In any case I thought it was worth adding to the known issues list as it isn't really addressed in the help/manual.

If you think it's a bug and want it to be addressed, please report it.

It's already been reported though it's not just the non-reacting length of the handles what's going wrong, the whole shape of the curve isn't representing the real interpolation. As lan-mLMC mentioned, unfortunately this is a longer existing OFX issue.

Done.

@NickHope  Not only the left handle has problem. 😳 The right ease out handle's length changing (hold angle to no change) can't affect the curve shape. But it should affect the curve just like what besier mask and magix video pro do.

Please fix the logged text. Thanks!

OK, I was too hasty, and only described part of the issue. I've taken it off again for now until we have a concise, accurate definition of the whole issue.

I found this. Any other previous discussion on this issue?

@NickHope I'm sorry I haven't seen these former threads. 😌 @Marco. @NickHope @lan-mLMC thanks for the reply!👍🏻

Seems like 2 related issues. The one I already described (which is more of a useful-to-know issue than a bug) and this, which feels like more of a bug (and goes back to at least VP12):

The length of FX keyframe spline curve handles has no effect on the shape of the curve.

If that's not fixable then it would be better if the length of the handles cannot be changed.

@NickHope You are right .
