This may be because the encoding format of the downloaded video is not supported by your local media player. For example, the HEVC (h.265) encoding in MP4 videos is not supported by many video players. We recommend using the VLC media player for playback.
FetchV can only detect generic video data. If the video data on the target website is processed in a special way, the extension will be unable to detect that video data.
In most cases, download speeds range from 200KB/s to 20MB/s. The download speed depends on your network conditions and the target video. If you are unable to smoothly play the target video before downloading, it indicates a poor network connection to the target video. Additionally, try not to play the target video during the download process to reduce bandwidth usage.
Tasks automatically suspend when there are more than 30 error requests. Continuous error requests are usually due to your network being disconnected or the requests being rejected. You can wait a moment and then click the "Continue" button to try again.
If you are downloading large videos, it is advisable to avoid doing so unless your computer has sufficient power and bandwidth. During the download, the extension caches data in this tab, utilizing your memory (released when closing the tab or saving the file to disk). The larger the video you download, the more memory it consumes. If your computer has insufficient memory, it may result in tab crashes. On the other hand, if you simultaneously download multiple large files and there is insufficient bandwidth and CPU performance allocation, it may also lead to task failures.
If you encounter download errors, it means that this downloader is unable to download the video for you. In this case, you can try using "Record Mode".
When you click the "Save" button, the file is by default saved in the browser's download directory. Normally, when saving a file, the browser prompts you to choose the download folder. If this prompt does not appear, you can find the downloaded video file in your browser's download history.
There are various types of playback technologies for online videos. This static video downloader is only applicable to videos that use generic playback technologies. If the target video website has modified its video playback technology, this downloader may no longer be suitable for downloading that video. You can try using "Record Mode" to download it.
Some videos are divided into several small segments when making the request. You will see a series of segment URLs in the extension's pop-up window, indicating that you cannot download the complete video. However, you can use "Record Mode" to download it in its entirety.
This means that the video's audio is loaded separately. You can use "Record Mode" to download the video in its entirety, or separately download the audio and video to your computer, then use other tools to merge them.
