Be cautious when downloading files with generic "VID" names from unknown blogs. These filenames are often used as "clickbait" in spam or malware-heavy sites. Always ensure you are on a reputable site before clicking download links.
If the video is playing on a page but there is no download button, you can right-click the page, select Inspect , go to the Network tab, and filter by "Media" or "video". Refresh the page and play the video; the direct .mp4 link should appear, allowing you to right-click and "Open in new tab" to save it.
Go back to the original blog post where you saw the name. Look for a Download button, a hyperlinked version of the filename, or a Google Drive link.
