Simply put: You can't practically do it. Once the text has been "burned" into the image, it is no longer text; it is part of the image itself, and in fact, the scene underneath the text has been irretrievably lost. Your question, in fact, is precisely the same as asking "How do I remove all the heads from all the characters in the sitcom?" If you've got a large (Hollywood studio-sized) budget, then yes, you can go frame by frame, and essentially paint in new scenery over the text. But that's not something for "the rest of us."

Now, if it's just a static, quasi-transparent logo, there does exist software to remove those with reasonable success. But a general solution does not exist.

i got some doubts. you used a word "burned text"
i didn't mean it. i didnot burn a disk. the video is still in my hdd. there are textual advertisements as stripes moving from left to write under the video frames. this text is not permanent as far as the video is concerned. it is a tv show, and today the broadcaster will show today's news items as the text and towmorrow it will be different.
any suggestions plz?

He didn't mean burned to DVD, he meant the text is now part of the picture. It's not like DVD subtiles where the text is a separate image that is overlaid onto a clean video as it is being played.

Notice that I said that the text is burned into the image. If you carefully re-read what I wrote, it explains what you need to know.

In case you are still confused, think of it this way: If one person stands in front of another in a video image, you cannot simply "remove" the person in front to reveal the one behind. The information about the hidden person is not present in the image, so there's no simple processing that will do the job. And so it is with text.

In your case, the text is most definitely permanently burned into the image. It doesn't matter that tomorrow's program will be different. We're talking about the show you stored on the hard drive. The text is not stored as a separate file -- it is a permanent part of the image.

"Burned" is not a literal term. It means permanently part of the image in this context.

Anyway, for moving text none of the usual logo filters will be much use. You can either blur the area (I see this often on news clips when the station wants to cover up another station's logo) or overlay it with a plain colour (usually black), or crop the bottom off the image (i.e. resizing it).

For blurring regions this VirtualDub filter is very easy to use:

Or use the built in "null transform" filter to crop the frame.

Then you can save it out as an AVI, or frameserve it to make a new MPEG.

suppose on the avtar of AlanHK,,, a text like alanhk is there in the middle of the picture. and suppose this is a video.what i mean is,, there is some text on the video i don't know whether it can be callled a textual subtitle or not. is it possible to remove the text? my present qtn is entirely different from the previous. now i am asking about the text on the video not under the frame as news items when we capture from tv shows.

Mask it over (cover it with black). Re-center the screen if necessary. I've had to do this before myself, to remove weather alerts and other such stupid interruptions.

It's easy to remove things. The hard part is replacing. The Xlogo filter (see https://forum.videohelp.com/topic333648.html) replaces areas by extrapolating in from the edges. You can't get the original image back, but it can reduce the distraction of a big colourful logo.
