Error Pops Up, Saying "No Audio Track"
Sometimes during execution, you may frequently encounter errors such as "Unrecognized, please check if the video contains an audio track." The reasons are generally as follows:
There is indeed no sound. Especially for videos downloaded from YouTube, the video and audio are usually downloaded separately and then merged. If an error occurs during the download, it may not be merged, resulting in only video without sound.
Solution: Re-download and check if there is sound after downloading.
There is sound, but the background noise is too loud, such as videos from streets or concerts, making it impossible to recognize any text.
Solution: Select "Keep Background Sound" or use a background noise removal tool to delete the background noise in advance.
The selected "Original Language" is inconsistent with the language spoken in the video. For example, if the video contains English speech, you should select "English" as the original language, but if you select "Chinese," it will definitely not be able to recognize the text.
Solution: Re-select the "Original Language" to ensure it is consistent with the language spoken in the video.
