adding 2 seconds of black?

Postby Rider4Z » Fri Jan 20, 2012 10:58 pm

i remember someone posting a long time ago that there was a script that would add 2 seconds (or so) of black before and after your video for convention purposes.

is that true and if so, any idea what it is? (i knew i should have written it down when i saw it)

Code: Select all

vid=avisource(file)
black=BlankClip(vid, 48)
black++vid++black


You can replace the 48 with 60 if your video is 29.97 instead of 23.976.

You can also do it like this, which might be slightly faster while encoding (though for something this small I doubt it's possible to notice the difference if there is any):

Code: Select all

avisource("file.avi")
blankclip(last,48)+last+blankclip(last,48)

That won't work; that'll give you two copies of the video with two seconds of black in the middle.

I actually wrote a simple function for this a while back: pad()

Save, and put it in your AviSynth plugins folder. Call it like this:

Code: Select all

avisource("file.avi")
pad(2)                            # adds 2 seconds of black, regardless of framerate, rounded to the nearest frame
pad(frames=24)                    # adds exactly 24 frames of black
pad(3.5, color=$FFFFFF, end=true) # adds 3.5 seconds, white, to the end.  Alternatively you can use pad_end()
