Loop background music to a target length
Your video is 4 minutes but the BGM loop is 12 seconds — copying and pasting in an editor is fiddly and the seam always lands audibly. All clips are resampled to one format and joined seamlessly, the joined loop repeats until it fills the target duration, and the last two seconds fade out for a clean ending.

Frequently asked questions
What do multiple files do?
They are concatenated in order into one longer loop source first — handy for verse + chorus pairs that should alternate.
What if the loop is already longer than the target?
It is simply trimmed to the target with the fade-out — no looping needed.
