plugin effect on adjustment layer has some issue when I use PF_OutFlag_NON_PARAM_VARY .

[smarts19193560]

Hi, All.

I hope you are doing well.

My plugin has some issue on adjustment layer when using PF_OutFlag_NON_PARAM_VARY  for out flag.

Problem:

Only the first keyframe's value works when I apply  keyframes to an adjustment layer.

How can I solve this problem?

err... what exatcly do you mean by "only the first keyframe's value works".

does you plug-in get a render cal for every frame, but AE fetches you the

wrong param values?

[smarts19193560]

For example, I applied plugin to adjustment layer and set 2 keyframes. I've set rotation angle to 30 degree on the first keyframe and 120 degree on the second keyframe. Everytime render is called, the angle should increase from 30 to 120 but it maintains 30 degree always.

This issue appears only when I use this flag - PF_OutFlag_NON_PARAM_VARY.

Also if I don't use adjustment layer and apply plugin to the actual layer, this issue doesn't appear.

Anthonie.

sooo... if you put a break point in your render function, you see AE is

sending the first rotation value on every frame?

i've never heared of such behavior. it seems more likely to me that AE is

caching the render result of the first frame and doesn't send any more

render calls.

i'm just trying to rule out the causes.

Thank you. shachar.

Sorry, I forgot a problem.

I converted the plugin to premiere pro and tested on that. So, above problem appears on premiere pro not AE.

ah... we'll, PP is not my field of expertise so i'm afraid i don't have any

insight for you on that one...

[smarts19193560]

Thank you. shachar.

Then may I ask about that on PP forum?

Actually the flag (PF_OutFlag_NON_PARAM_VARY) is in AE_Effect.h.

So, I asked about that here.

you may ask wherever you feel is appropriate! this forum is not being

policed.

you can also try contacting zaclam directly. it might be a bug with PP.

[smarts19193560]

Thanks for your help.

Can I contact zaclam directly to solve this problem? Or can he see this question?

Anthonie.

he usually looks at this forum and responds when needed, but you can also

send him an email. (i think the address is in the SDK pdf)

Hi, Shachar.

Can I use another out flag not PF_OutFlag_NON_PARAM_VARY to call render function every time?

Regards,

Anthonie.

[shachar carmi]

before you do that, know that PF_OutFlag_NON_PARAM_VARY should work...

in AE you can try using GuidMixInPtr(). i'm pretty sure that doesn't apply

to PP.

perhaps you can try creating a simplified plug-in to see if indeed PP is

ignoring PF_OutFlag_NON_PARAM_VARY.

if the simplified plug-in gets called you'll know it's something else in

your design that causes the issue...

[smarts19193560]

Hi, Shachar.

I checked on a simple plugin - shifter. Without PF_OutFlag_NON_PARAM_VARY flag it works well with adjustment layer.

But when I add the flag to the plugin the error appears.
