Marble race music

Marble race music: record your friends, whoever leads sings

Give each marble its own sound: you hear the marble in the lead. When another marble takes the lead, the sound switches to its own, live and in the exported video. Record your voice, or your friends or your band with their OK, or use any sound you made or have the rights to.

How it works

From your sounds to a race video in three steps

  1. 1

    Try a race right away

    The button opens a flag race in your browser, with no account needed. That race has no sounds yet: sounds come with a free account (next step).

  2. 2

    Add the sounds

    With a free account, create a custom marble on the hub with a picture and a sound, or add a sound to a flag. Each sound file can be up to 4.5 MB.

  3. 3

    Race and export

    Run the race, then export it. Plynox checks the account's export allowance and watermark status before encoding.

Frequently asked questions

Is it free?
Yes. A free account includes 3 watermarked video export credits every 7 days shared across Plynox, with no card required. Creator Pro unlocks unlimited exports without the Plynox watermark.
Is the race timed to the song?
No. It is a real physics race, not a race cut to the beat. Every sound plays on a loop from the start of the race and only the leader's is heard, so when a marble takes the lead you hear its sound from wherever its loop has reached, not from the beginning. A race and its video last at least about 75 seconds, so a short sound repeats. There is no tool to trim a sound or pick where it starts. Short sounds work best; trim yours before you upload it.
Does Plynox provide voices or songs?
No. Plynox does not provide voices, singers or songs. Record your own voice, or your friends or your band with their OK, or use a sound you made or have the rights to. You need the rights to everything you upload and publish. Usage rights for your videos
How many marbles can have a sound?
A free account saves 2 custom marbles and 2 flag skins, each with its own sound. Creator Pro saves up to 50 custom marbles and races up to 30 at once.
