If you plan to send us your audio tracks as individual files we recommend industry standard file formats like WAV (or AIFF).
We won’t accept your source audio as MP3 (or similar compressed formats) since the resulting quality wouldn’t be able to meet professional cinema standards.
If you plan to send us your audio tracks as separate files, please make sure to use distinct file names for each track, so that we can clearly identify each track’s designated channel mapping.
PLEASE NOTICE: You should make absolutely sure that your audio stream is perfectly in sync with your video stream! (First Frame of Action / Last Frame of Action).
