SeamlessLoop
Automatic dissolve-based video looping
Builds a smooth video loop by overlapping the beginning and end of a clip with a controlled dissolve region.
This tool belongs to the Krokodove set integrated into DaVinci Resolve 21 and Fusion Studio 21. See the complete Krokodove node list and the comparison with native Fusion tools.

DaVinci Resolve · Fusion
SeamlessLoop helps create an endlessly repeating clip by defining the loop duration and transition length, then blending the temporal boundary.
Overview
What SeamlessLoop does
Loop Length establishes how much source time belongs to the repeatable section. Dissolve Length defines how much of the end overlaps the beginning.
Fade Type controls the transition curve. The informational frame readouts help verify how much source material the selected settings require and where the effective loop begins.
The method works best when the beginning and end are visually compatible. No dissolve can fully hide a large change in camera position, lighting or object state.
Mental model
Think of it as folding the end of the clip back over the beginning and crossfading the overlap until the join disappears.

Practical setup
A reliable workflow
- 1
Choose source material with compatible beginning and end states.
- 2
Set Loop Length for the intended asset duration.
- 3
Increase Dissolve Length until the cut disappears.
- 4
Choose the Fade Type that best matches motion and brightness.
- 5
Play several consecutive loops to check for rhythmic or exposure pulsing.

Troubleshooting
Common mistakes
Using source material with completely different start and end compositions.
Making the dissolve so long that motion visibly doubles.
Checking only one loop instead of several repeats.
Production notes
Practical tips
Trim the source first so the start/end states are already similar.
Use a shorter dissolve on fast chaotic texture and a longer one on slow ambient motion.
Check luminance continuity as well as motion continuity.
