Personally, I think a text strip has been sorely missing from the sequencer (and compositor) for a while, and it's great to see it added. Doing it via blender scenes and python is a really slow, nasty overcomplicated way of doing something which really should be quite simple, and is a really simple, common, basic tool in most other editors.
Editing the text from the sequence editor interface and having it rendered directly to a strip is the fastest and best way of having such a feature, and it's something I would have loved to have had plenty of times. Note: I haven't tried the current patch but it would be best as a generalised 'text strip' rather than anything aimed specifically at title cards, with properties like text box height and width, and typographic/paragraph controls too. cheers Matt On Thu, Jun 16, 2011 at 9:26 PM, Joshua Leung <aligor...@gmail.com> wrote: > Hey Peter, > > Cheers for the feedback! > > Indeed, as I started to pick through things, the issues faced by users > who would want to use this as a base on which to start extending it in > some ways did come up.
