Pop-up error says "No audio track"
Sometimes during execution, you may frequently encounter errors such as "Cannot recognize, please check if the video contains an audio track." The reasons are generally as follows:
There is indeed no sound. This is especially common with videos downloaded from YouTube. Typically, the video and audio are downloaded separately and then merged. An error during the download process might cause the merge to fail, resulting in video without audio.
Solution: Re-download the video. After downloading, play it to check if there is sound.
Sound exists, but the background noise is too loud. For example, videos recorded on a busy street or at a concert might have noise so loud that no speech can be recognized.
Solution: Select the "Keep background sound" option or use a background noise removal tool in advance to delete the background noise.
The selected "Original Speech" language does not match the language spoken in the video. For example, if your video contains only English speech, you should select "English" as the original language. If you mistakenly select "Chinese," it will certainly fail to recognize any text.
Solution: Re-select the "Original Language" to ensure it matches the language spoken in the video.
