Set the "proxy_render_size" value?

Hi all.

Disclaimer: I’m a total noob when it comes to Python and Blender.

I’m trying to set the “proxy_render_size” via python in blender.

Some googling I’ve found:

and also can see the tooltip in Blender which says:["Video Editing"]...proxy_render_size

I’m not sure what the “…” means

I’m trying to automate the process of setting up proxies and have found the following statements work:

import bpy["Scene"].sequence_editor.sequences_all["C0010.001"].use_proxy = True["Scene"].sequence_editor.sequences_all["C0010.001"].proxy.build_50 = True["Scene"].sequence_editor.sequences_all["C0010.001"].proxy.use_proxy_custom_directory = True["Scene"].sequence_editor.sequences_all["C0010.001"] = "E:\Scratch"


As you can see it’s not really a script yet, I’m just poking at the parts I will want to set.

I just can’t figure out how to tell blender to USE the proxies I’m going to create.

Any suggestions?
