LTX-2.3_-_FLF2V_First-Last-Frame_custom_audio 48fps?
Hi @RuneXX the workflow LTX-2.3_-_FLF2V_First-Last-Frame_custom_audio.json works well but when i try and go higher than 24fps to 48fps or 50fps the video quality breaks down and its blurry (i'm using two images and a custom audio music file)
Is this happening for you too? if so is there a way to improve it please as i need more motion for one of my projects and I really need the higher framerate
Thanks!
Odd. Shouldnt matter what FPS you set, the model can handle 48 and 50fps.
that being said, i always use 24fp. I'll try the double, it could very well be that that needs more steps. Will give it a run
@holycowdude
If RIFE VFI gives too bad quality, i think FILM VFI is slightly better when it comes to interpolation (although a lot slower). Especially in fast movement scenes, RIFE tends to be a bit "meh".
If you decide you go the interpolation route for 48 fps instead of generating 48 fps that is π
Thanks for the suggestion but the quality is so bad due to motion blur / artifacts it cant be fixed with interpolation...
I have used 48-50fps with ltx2.3 on @RuneXX 's other amazing workflows but it would be cool if it could work in this workflow as i've got a character dancing so the motion at 24fps is killing it.
