Change sequencer image strip filename through python

Question

i'm trying to access and change the filename of image strips in the sequencer for a little addon i'm developping, but i'm stuck with invalid syntax, i think, and i can't find the correct way to put that... Here's what i've got so far :

import bpy


for scene in bpy.data.scenes: 

    if scene.sequence_editor is not None:

        strip = scene.sequence_editor.sequences_all

        if strip is not None:
            for obj in strip:
                if obj.type == 'IMAGE':

                    obj.elements.Sequence_Element.filename="ok"

But last line doesn't work... Does anyone have an idea about that ? Or know the correct way ? Thank you very much !

Answer 1

The Sequencer Strip has a name property, which is assigned by the user in Blender. It also has an SequenceElement list which contains all "file" elements of that strip. (Especially with image sequences you have multiple files.) We need to access the SequenceElements filename property. Image strips only have a single SequenceElement which will be indiced with 0.

The correct code is:

import bpy

for scene in bpy.data.scenes: 
    if scene.sequence_editor is not None:
        strip = scene.sequence_editor.sequences_all
        if strip is not None:
            for obj in strip:
                if obj.type == 'IMAGE':
                    obj.name = "ok"
                    obj.elements[0].filename = "ok.png"
