Error: "No Audio Track"
When processing, you may frequently encounter errors like "Unrecognized, please check if the video contains an audio track." Common causes include:
No audio exists. This is common with videos downloaded from YouTube, where video and audio are downloaded separately and merged. If the download fails midway, merging may not occur, leaving only video without sound.
Solution: Re-download the video and play it back to verify the presence of audio.
Audio is present, but background noise is too loud. Examples include street recordings or concert videos, where noise can interfere with speech recognition.
Solution: Select the "Keep Background Noise" option or use a noise removal tool beforehand to eliminate background noise.
The selected "Original Language" does not match the spoken language in the video. For instance, if the video contains English speech but "Chinese" is chosen as the original language, recognition will fail.
Solution: Re-select the "Original Language" to match the language spoken in the video.
