Thumbnailing a movie

[jaffy1229]

Hi,
I have never been able to find a util to make thumbnail indexes of movie files. Is there anything out there that can simply take a snapshot of a movie frame at a given interval? Say every 1 minute.

If anyone knows of such a util, I'd be very grateful.

Cheers,
jaffy

a simple avisynth script should do what you're looking for quite easily, something like

dgdecode_mpeg2source("c:\folder\project.d2v")
selectevery(1500,0)

will select a frame every 60 seconds (for pal content anyway)

load the script into virtualdub, go file-->save image sequence to end up with a bunch of images

Thanks for the info. I had a problem though when loading the script. Vdub said 'variable not found'

Should c:\folder\project.d2v be changed to reflect my movie file? And should selectevery(1500,0) be on the second line?

I've tried all possible ways but still get that error. Do you know what could be the problem?

the script i posted above is more of a guideline;

what is your source? an avi file? VOB/mpeg2?

[jaffy1229]

The file I was trying is an avi (DivX)

[anonymez]

1. install avisynth

2. run notepad and type in the following

avisource("c:\folder\video.avi")
selectevery(1500,0)

ofcourse adjusting path and file names to match yours, and yes on separate lines

3. go file-->save as, and call it whatever you want, just add .avs on the end, eg. myscript.avs

4. run virtualdub, open the avs file

5. go file-->save image sequence

If you mean more like a page of thumbnails, check out Media Player Classic. It can generate a single image with a x*y grid of thumbnails.

Thanks a lot for the help! It's working now.

Sounds interesting, I'll give it a try.
