How do I calculate the transition offset for multiple clips?

The offset is the timestamp when a transition begins. For multiple clips of equal length, the formula is generally (Clip_Index * Duration) - (Clip_Index * Transition_Duration).

Does this skill handle audio transitions as well?

Yes, it provides specific implementation patterns for the acrossfade and afade filters to ensure audio transitions are perfectly synchronized with the video effects.

What happens if my video clips have different resolutions?

The skill provides scaling and padding filter chains to normalize all input clips to a consistent resolution and framerate before applying the transition filters.

Can I create custom transition patterns?

Absolutely. The skill includes a guide for the custom transition expression engine, allowing you to use variables like X, Y, W, H, and Progress to define unique visual behaviors.

What is the xfade filter in FFmpeg?

The xfade filter is a high-performance FFmpeg component used to create transitions between two video streams, supporting over 40 built-in types like fade, wipe, dissolve, and zoom.
