F1 support with timestamps

[siraxe]

Vibe coded this one , separated encoder for timestamp prompt blending like it's done here I believe

Did it in separate file , seems to work

This is pretty cool! If they don't want to merge this PR I'll consider maintaining this node if you'd like. Then I can push any improvements I make to the timestamped prompts to both.

@colinurbs sure if you want to 👍
Made this one as a test and it worked , it added prompt_blend_sections as well and I didn't figure out how much those affect anything ))
Also I believe end_latent/embeds don't work with F1 , it just left them for now

@siraxe Could you please let me know which specific F1 model you used?
If possible, could you also provide a download link?
I'd really appreciate it if you could include an example workflow as well. Thanks in advance!

How would you prompt when you want to include common parts for each scene? Does it accept text outside of timestamp signiture?

@siraxe
Im tryin to test this one, but im getting this:

Can you advice what im doing wrong here?

thanks

@BartaG512 I used default F1 model , not sure about text outside time stamp but there's condition to just work normally if there's no timestamps I believe
@cgtarmenta mm not sure , maybe using end_embeds/latents with it (its not supported here)

This guy combined stuff and optimizing it here , has links to models as well
Can try his rep and he has examples as well that might be helpful )
