Extend the last scene strip to frame_final_end + 1?

[Botmasher]

The last scene strip stretches to but does not include the very last frame. This is expected since the script sets the new scene strip's frame_final_end to the scene's frame_end, but is a blank final frame the intended behavior?

Otherwise this script runs well here – I haven't seen a single logged error. It could even be the start of something like animated multicam switching.

Thank you for testing it and thank you for your suggestion. It is now corrected. Is the animated multi-cam switching, you have in mind, something like this? https://github.com/tin2tin/PrevizCameraTools

Sorry didn't necessarily want to close this now.

Nice! Though now I'm seeing the last frame extended as in a hard cut. Compare that to what happens during a normal scene strip add (the top channel).

Maybe one path forward could be setting length to the next marker in the list instead of adjusting strip frame starts and ends?

(Multicam - I'm not sure. I previously tried your Previz, which seems to bundle tools for greater control over scene cameras while editing. The multicam idea is switching between camera angles for different shots of the same animation. But that's probably another issue or feature request. 🤔)

It must be hardcoded in Blender, that scene strips only are added with a duration till the end of the preview area minus one(a bug?).

A hack. Adding this before adding the strip:
bpy.context.scene.frame_end=bpy.context.scene.frame_end+1
And this after adding the strip:
bpy.context.scene.frame_end=bpy.context.scene.frame_end-1
Will make it look like you suggest.

However, I found out that, if a clip is added outside the preview area things will mess up(negative duration?). So I think I'll auto-prolong the preview area with 30 fps *5 sec and do the add/subtract hack.

On the previz add-on. The main idea of it was to do all multi-camera switching and editing in the sequencer and not use 'bind camera to markers' at all. These are the core functions shown here: https://www.youtube.com/watch?v=b4eQrns5KpQ Eg. using the 3D View as the preview for the Sequencer and adding cameras directly into the Sequencer. As you can move the strips where you want them, you can have multiple cameras showing the same animation(same frame-range) over and over again from different angles. Was that what you meant?

That's a clever little workaround, and it works fine here. 👏

Previz - ah, ok. That does sounds and look like it. I should play with that a bit more.
