🐇 RIFE Seam Timing Analyzer

Finds a smooth loop timing: measures motion in your clip and solves a set of t-values across the wrap [last→first] so the seam blends naturally.

Inputs (14)

Name	Type	Default	Description
ckpt_name	COMBO	rife47.pth	Choose the RIFE 4.7 or 4.9 model file (used only to test candidate timings).
scale_factor	COMBO	1	Quality vs speed for the probe renders. 1.0 recommended.
ensemble	BOOLEAN	true	Blend forward & backward predictions to reduce artifacts (slower).
full_clip	IMAGE		Your input clip (≥2 frames). Real motion here decides the loop seam timing.
multiplier	INT	4	How many new frames you plan to create at the loop seam [last→first]. Set 0 to skip.
use_first_two	BOOLEAN	true	Match the motion between the first two frames in your clip.
use_last_two	BOOLEAN	true	Match the motion between the last two frames in your clip.
use_global_median	BOOLEAN	false	Use the median motion across the whole clip (needs ≥3 frames). Helps ignore outliers.
calibrate_metric	COMBO	MSE	How we compare frames while solving: MSE (more sensitive) or L1 (more forgiving).
calibrate_iters	INT	124–24	Search depth per solve. Higher = slower, but a tighter match.
t_min	FLOAT	0.0000–1	Earliest allowed blend point at the seam (0 = exactly the last frame).
t_max	FLOAT	0.9600–1	Latest allowed blend point at the seam (keep below 1.0 to avoid sticking to the first frame).
auto_tmaxopt	BOOLEAN	false	Automatically push the upper limit closer to the next frame to hit the target motion step.
t_capopt	FLOAT	0.99500.5–0.9999	Safety cap used with the auto upper limit (keeps it just shy of 1.0).
