Just trying to work out if it is possible to use the video effect and have it rotate around a tree as I have not been able to work out the best method to do this.
If I use the RotoZoom feature and change the X axis then this doesn't seem to work correctly as all it does is compresses the video and then flips the video.
So hoping someone may know how to do this correctly

I must be missing something here as I cant get a video to just rotate around a tree.
I have a video of santa running, jumping and skipping which I then want to make look like he is doing this around the tree but cant seem to get it to work, so any suggestions would be appreciated

Show us your subbuffer value curves? Or is your question how to set them up.

Yes I am having difficulties in knowing what to do to set these up.

When you say sub buffer are you meaning the sub buffer within a sub model of the tree model because if this is what you are talking about then im not sure how this gets me to make a video rotate around a tree. Im a bit confused

looks like I may have got close last night as the sub buffer you refer to must be the black buffer box in the layer settings window. Right click on that and then go to edit.
if that's the way you get to the curves, then I just need to play around a little more to get it to work the way I want. Hopefully that's what you are talking about
 
I had a quick go just now at lunch and I seemed to get a video to go from centre of megatree to scroll around off to the right over 5 seconds.
It was using the value curves in the right-click Edit menu on the buffer field under Layout Settings.
However, I managed to crash xlights when i tried to make it -100 to 100 (full left to right wipe) over 5 seconds, so hopefully xlights can handle crunching all the pixels that quickly. This was only a 16 string megatree 5 second effect, no other effects/models in use...
I will also note I was running from a portable HDD 2018.16
 
Ive been able to get this to scroll around the tree, but not sure if I can make it do multiple rotations whilst keeping the full video on the tree the whole time instead of disappearing and then reappearing. Im trying to have multiple rotations around the tree which appears seamless

Doable but you are going to need layers and multiple videos carefully timed.

Its unfortunate its so difficult to do this as when I used LSP back in the day we could easily rotate a video around a tree left and right, up and down and so on, as well as change the video speed and size
I will have to give this some thought on what to do as I was planning on using lots of video with customised animations that I have created, but the current feature set for the video effect is fairly limited on what can be done and requires a bit more thought and effort than I was hoping for to do what I want
I may have more luck creating a series of animated picture files and using the picture effect instead, but that just creates more work but may be a way of getting the result I want.
It can be done the way you say but will take a bit of extra work in getting this all timed to work seamlessly

I appreciate your help Keith
 
Video speed and size is trivial to change. Motion is as you see based on buffers.

The picture effect has vectors and can display movies but to do so you need to use Ffmpeg to break the video up into lots of still frames. Not used much any more but the functionality still exists.
 
My solution is to use animated GIFs which seems to work well for my needs as the animation software I am using can export directly to an animated GIF which pretty much gives me the solution to do what I want.
