Hey all,

I have a litle problem with Video Posts, I feel kinda dumb about this topic, because it seems so simple and I still can't get it to work.

If have this code here:

doc = c4d.documents.GetActiveDocument()
rd = doc.GetActiveRenderData()
if rd.GetFirstVideoPost() != c4d.BaseList2D(1001008) : #This is the Color Correction VP
	rd.InsertVideoPost(c4d.BaseList2D(1001008))
  

What I am trying to do, is when the user enters a special View in my plugin I want to load the CC VP into the render settings, but what I don't want is, that the VP gets imported more than once.

I don't really know why, but the VP gets imported every time. 
I hope someone can help me with this

greetings, 
neon

Hi neon,

two things:

You are only comparing the first VideoPost, which will fail, when there's already another VP added. Instead you will need a loop to check all VPs.

You shouldn't compare the objects. That's bound to fail an d I'm pretty sure, that's your actual problem. With your comparison:

if rd.GetFirstVideoPost() != c4d.BaseList2D(1001008) :

you are comparing the VideoPost object to a freshly created one.
Instead you should check the type of the VP.
Something like this:

vp = rd.GetFirstVideoPost()
while vp is not None:
  if vp.CheckType(1001008) :
    break
  vp = vp.GetNext()
if vp is None:
  rd.InsertVideoPost(c4d.BaseList2D(1001008))

Hi Andreas,

thank you for your reply.
I wasn't aware of the vp objects, and that it would fail.
Now I know how to compare the video post properly

Also thank you for your example code!
