An error pops up, saying "No audio track"
Sometimes during execution, you may frequently encounter errors such as "Cannot recognize, please check whether the video contains an audio track". The reasons are generally as follows:
There is indeed no sound, especially for videos downloaded from YouTube. Generally, the video images and sound are downloaded separately and then merged. It is possible that an error occurred during the download, and the final merge failed, resulting in only images and no sound.
Solution: Download again, and play it after downloading to check whether there is sound
There is sound, but the background noise is too loud, such as videos on the street or concert videos, which makes 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 speaking language in the video. For example, if the voice in your video is English, you should select the original language as "English", but you selected "Chinese", then it is definitely impossible to recognize the text.
Solution: Re-select the "Original Language" to ensure that it is consistent with the voice in the video.
