is it possible avi script can extract the subtitle from a video file ?

[adrianmak]

I ve have video format with embedded subtitle. I want to extract the subtitle text and save into say bmp and remove all the background if possible, then I can pass to a OCR software to regonized the text into editable text.

the newest versions of subrip can take hardsubbed video and OCR it directly.

a word of caution though - its tolerances are quite low, so you'll be entering the same letters over and over again, often within the same subtitle. it's fine for digital or broadcast stuff, but anything off an analog tape (like VHS) will have difficulties because of timebase errors (wibbling horizontal lines).

subrip can take avs files, so it's possible that if you filter your video in the right way it'll have a better success rate. but as it is, it'll take you about a day to get the subs out.

is it able to open rmvb format ?

When I tried open the rmvb file with avs script in vdm, vdm return
"First element in file is not EBML"

my avs script is
DirectShowSource("F:\hero.rmvb", 23.976, true, false, true)
ConvertToRGB24()
