Hi,
I have a home video and want to upload it on my website but there is some markings on the video
Can I clean those marking so no one can read them while playing video
They are on the left lower corner of the video
If there is any software to clear them please let me know
Thanks

Nearest I can suggest (without paying anything) is VirtualDub; you can use it to crop your video in such a way that the markings get left out. Of course, this means that the video will be a few pixels shorter and narrower, so if you have anything important on the bottom of some of the frames that you want seen, it wouldn't work too well.
