Conditioned media frame count

[WSINTRA]

Keep running into issues around frame count when using conditioned media, I'm trying to loop the previous created video back into the pipeline. I have set the frames generated to be n_frames % 8 (97) previously i had it a 96 and it gave me the error.

pythonDevelopments/LTX-Video/ltx_video/pipelines/pipeline_ltx_video.py", line 1443, in prepare_conditioning
    assert n_frames % 8 == 1
           ^^^^^^^^^^^^^^^^^
AssertionError

I figured changing to 97 would fix it, but I still get same error. Can someone help me understand this requirement around n_frames % 8?
