Is there a way to erase titles from a video?

Post by ldor »

Hi,
I need to erase titles from a video. I am thinking of a filter that could do it. In principle that should be possible. As normally titles are made using a single color (unless there is a border), one could specify the color and then the filter could detect all pixels with that color and replace them with the nearest background. But does a filter like that exist? (I tried average and blur filters but the effect was not exactly as I would like.) Maybe there are some third party filters that could do this?
Would appreciate any suggestions

Your best bet is to google for "remove text from video". You will get lots of hits

Without seeing a captured frame, it's hard to say. That being said, if the text is at the bottom of the frames then perhaps you could simply crop it out. An alternative would be the brute force approach of overlaying an object or text on top of the existing text.

Your filter idea sounds dubious, since for example, if the text was white and the frames contained scenes with snow and/or clouds, then you'd end up with a mess.

In addition . . assuming the video in question has been captured from somewhere like YT
It depends on where in the video the titles occur, and for how long:
1. at the start - for a few seconds? just trim them out.
2. at the bottom - as for example the progress/duration time in a YT clip - the cropping suggestion already made is how I get rid of them when I have to do this.

If the titles are not large, are all the same colour and they stand out from the background (sort of basic but needs saying) you could try a green screen approach, but what would you replace them with would not equally stand out??
