Switching to MovieGo — a Go library that wraps ffmpeg with a lazy, declarative clip graph — resolved these issues. Key challenges with MovieGo included enforcing uniform pixel dimensions via padding, computing correct frame rates as rational numbers accounting for crossfade overlap, choosing hard cuts over crossfades to avoid ghosting on crisp linework, switching to Catmull-Rom interpolation for sharper resizing, and handling audio length mismatch. The final output encodes in seconds as a single Go binary with two dependencies. ## Full article daily.dev links to this article rather than hosting it.
