Check the join between repetitions before exporting a longer loop.
Use the Loop Video alongside this illustrative example.
A practical example
A ten-second clip repeated six times is roughly a minute of material, but an obvious jump at each join can make it unsuitable as a background. Watch the last second followed by the first second. Choose a calmer section or a deliberate transition in an editor if the motion does not connect.
Check the result
Check the audio boundary too: a cut in a musical phrase may be more distracting than the visual jump. Test a small repeat count before a long export to avoid spending time on a flawed seam.
Try a comparison
Compare two repetitions with three before requesting a long loop. Each additional join introduces another chance to notice the seam. If the two-copy version already has a click or jump, fix the source section before generating more repetitions.
What this does not establish
Repeating footage does not create new detail. Large repeat counts increase output size, processing time and memory demands.
