View Full Version : Plugin to place a blur overlay that changes every X frames

I'm sure someone answered this before, but here I go again anyway...

Say I have some video (in this case from some old video from a camcorder) that annoyingly has the time, including seconds, displayed on a large chunk of the screen. For a number of reasons I'd like to obscure this counter, mostly because it's distracting. Now I could just use a giant block blur overlay (or XLogo) to take it out, but I'm inspired to go for something a bit more... precise. Here's what I'm looking for:

I'd like something that'll take a series of bitmaps (representing overlay patterns, e.g. the shape that just covers the number 0, then the shape that just covers the number 1, etc.) and generate a blur-blend overlay in a set place, in the shape of the current bitmap, which cycles to the next bitmap every X frames. Make sense? Oh yeah, I realize XLogo works fairly well, but something that was a bit more detailed in its blur method would be nice too.

Okay, now if I were a plugin that did that, where would I live?

You could use a series of 10 selectevery's to select each digit type. Then masktools, maybe one of the impand methods, to neutralize each digit. Interleave the 10 subclips back together. Apply to each digit position. Finally apply very strong temporal filtering to the digit regions using layer/overlay/masktools to get rid of the resultant flicker.

Of course it would be a lot simpler to just overlay appropriate opaque blocks over the digits.

Hmm? You can load VirtualDub plugins in AviSynth.
