Parameters

NameTypeDefaultDescription
video_url *Translated Videovideo_uploadProvide the translated target video. Because the video length may change after translation, this translated video is required as the target for lip sync.
audio_url *Translated Audioaudio_uploadProvide the translated audio that matches the translated video. The caller is expected to prepare the translated audio, and the service only requires that the ASR segmentation can align with the subtitle timing.
subs_list *Translated Subtitle SegmentsarrayProvide sentence-level ASR timing for the translated video. Because the translated video length can change, these subtitle segments must match the translated target video.
original_video_url *Original Videovideo_uploadProvide the original source video uploaded by the user. This is the reference video used to preserve the original mouth movement structure.
original_subs_list *Original Subtitle SegmentsarrayProvide sentence-level ASR timing for the original source video. The original and translated subtitle segmentations need to stay aligned between the two videos.
