Remove Static Pixels from a Video to Mimic a Green Screen Effect [closed]
2 août 2021, par nKrkanI have a video that's 50 seconds in length, resolution of 480x480 and 16 frames per second.


There is a person talking in it, with the background being static I thought if there's a way

to remove those static pixels (background) and just extract the moving pixels (foreground)

and possibly mimic a green screen effect ?

I was thinking on writing a picture-by-picture comparison tool to do such thing but I don't

believe I'm up to the task, or maybe It's laziness.

And now I know, some of you will point out that the video has compression artifacts and that

might cause some problems but It doesn't have to be Studio quality stuff.

I tried the ffmpeg command from this question : Remove random background from video using ffmpeg or Python

And it does mask the person, but... I couldn't quite get it to work, apparently putting the

reference image in the input makes that image burned into the video, thus having no way to

remove it, but it did mask the background as black and the person as greenish, so still not a

viable way to do it.

Have also tried some Python projects I've found on the GitHub but none of them worked as

I expected.

So, what I thought to do is simply compare the first and the second frame of the video, check

all the pixels by comparing them with the two sources, and change those that stay within a

certain range of the initial pixel value.

I should point out I'm not very knowledgeable with mathematics and the majority of the

methods used in these type of things, but perhaps someone could point me to an interesting

source to read and learn, or by providing an alternative to the methods aforementioned above.

ac3enc : do not clip coefficients after transforms
9 janvier 2021, par Lynneac3enc : do not clip coefficients after transforms
In either encoder, its impossible for the coefficients to go past 25 bits
right after the MDCT. Our MDCT is numerically stable.
For the floating point encoder, in case a NaN is contained, lrintf() will
raise a floating point exception during the conversion. -
