Reply To: Rendering video with transparent background in Blender 4.1

HI Harlen,

I have never used Quicktime, but I don’t know of any changes between 3.6 and 4.x in that area.

What Omar mentioned, is probably not applicable here, but just in case; if you Render Frames, Blender, by default sorts the .PNG’s by Modified Date and that can be different than the Frame order, causing Choppiness, because the Sequence gets in the VSE in the wrong order. This typically only happens when Rendering with EEVEE. You can change that to sort by Name and it should be okay:

Like I said, this is probably not the case for you, but it could be, that Rendering speed has improved and if it’s a sequence rendered in 4.x, it could be sorted in a different order than if rendered in 3.6 (With EEVEE in both cases).

So, basically, what I am saying is: I have no idea.

Maybe consider filing a Bug Report?
