auto dubbing faq
what is auto dubbing?
auto dubbing is the process of automatically syncing your video to translated audio using ai. upload your video and the translated audio track, and sync. labs matches the lip movements to the new audio. unlike manual dubbing which requires video editors and frame-by-frame adjustments, auto dubbing handles it in minutes with zero manual effort.
how long does auto dubbing take?
most videos are auto-dubbed in under 3 minutes. processing time depends on video length, but even longer videos typically complete in a fraction of the time manual dubbing would take.
can I auto-dub multiple videos at once?
yes. you can upload and auto-dub multiple videos in batch. queue up your videos with their translated audio tracks and let the ai process them all.
do I need any editing skills?
none at all. auto dubbing is completely hands-off. upload your video and translated audio, download the result. no timeline, no audio editor, no manual syncing.
