Hello,
I understand that you're having trouble downloading a video from Google Drive using IDM (Internet Download Manager), as the "Download this video" pop-up does not appear for certain videos. You've noticed that the pop-up usually appears after the video starts loading, but for some videos, it immediately starts playing without the option to download.
While IDM is a popular tool for downloading videos, it may not work on all platforms or websites consistently. In the case of Google Drive, there might be some limitations or restrictions that prevent IDM from detecting the video for download. However, there are a few alternative methods you can try to download the video:
1. Use a different downloader: Aside from IDM, there are several other download managers available that might work better for downloading videos from Google Drive. Some popular options include JDownloader, EagleGet, and Free Download Manager. You can try installing and using one of these alternatives to see if they are able to detect and download the video properly.
2. Download via the Google Drive app: If you have access to the video on a mobile device, you can use the Google Drive app to download it. Simply open the video in the app, tap on the three-dot menu icon, and select the "Send a copy" or "Make a copy" option. This will create a new copy of the video file which you can then download to your device.
3. Use a screen recording tool: If all else fails, you can resort to using a screen recording tool to capture the video as it plays on your screen. There are various screen recording software available for both computers and mobile devices. Simply start the screen recording, play the video, and save the recording once it's complete. Keep in mind that this method might result in a loss of video quality compared to downloading the original file.
Remember to respect copyright laws and only download videos for personal use or when you have the necessary permissions. I hope one of these methods helps you successfully download the video you're interested in. Let me know if you have any further questions!
