Zoom in on mpeg movie scene ????

[Rickyblaze]

I was wondering if anybody coukld advise me as to what method I could use to zoom in on an mpeg movie that was taken to far away and edit or resize it so you could make out the subject. My wife recently took a movie of my Daughter's first dance program at a football game but failed to use the zoom feature of our Panasonic PV-DV203 and I was wondering if there was such a program that I could use to zoom in on the scene a little and save it as such.

Thanks,Rick

You could use virtualdub to crop and resize, but the quality would probrably be terrible (depending on how much you are zooming in)

Just an idea.....

What I would do is get the image(s) (video sections) of your daughter - as best you can - and resize just that portion (her) and put that in an overlay that runs along with the main video. A sort of pic-in-pic solution. Perhaps just in select moments - not the entire length of the video.

You can have it fade in/out or even zoom if you have the right software to accomplish that.

That way, even if the image of your daughter is quite blurry, at least she'd stand out and not leave you with an entirely blurry video. I bet it'd make her feel pretty special too. :c)

Just for your consideration.

Best of luck with it.

There is a Zoom filter for Vdub
It dynamically zooms in over a set amount of frames.

I have a zoom function for AVIsynth
if anybody is interested.

And of course most of the Fancy editors have it


You can't zoom very much you know - you start seeing individual
pixels.

Thanks for the replies guys I will try your suggestions and see which one works the best for my application. I realize that the more I zoom the worse the pixel problem becomes but all I realy need is a little bit of zoom effect .

Thanks,Rick

If you use AVISynth, use that to do it, otherwise try using VirtualDub.

I should have looked a little closer at the VideoStudio Program I have been using,It has a cropping filter for video and I can zoom in with it. It does get a little pixelated but if I keep it to minimum it suffices.


Thanks,Rick

I will push this to the top 'cause I've got the same problem, but unfortunately my editing program (Pinnacle Studio 8) doesn't allow me to zoom in.
So I was hoping if anyone can tell me EXACTLY how to zoom in on a special section of the video using VDub or AviSynth - preferably VDub since I don't like the AviSynth script thing ...
I would be thankful for every help you could offer me - thx a lot!

This zooms in a factor of 4 from frame 100 to 500
and zooms back out

#Avisynth
v = avisource("cartoon1.avi")

v2 = Animate(100,500,"ZOOM", v , 1.0 , v , 4.0 )

v3 = Animate(501,1000,"ZOOM", v , 4.0 , v , 1.0 )

return( trim(v2,0,500) + trim( v3,501,0 ) )

Function ZOOM( clip c , float f )
{
W = c.width
H = c.height

L = int(W*(1-(1/f))/(2.0))
T = int(H*(1-(1/f))/(2.0))
W2 = int(W/f)
H2 = int(H/f)

v = crop(c,L,T,W2,H2)
v = BicubicResize(v,W,H)

return( v )
}

The Vdub Zoom is a plugin

thx a lot for your answer! one more thing: where do I get the VDub plugin from?

I like Gees answer! I will use it on some of my vacation footage I am now working on. Thanks for the idea!! Also, it would make a really nice guide!!

[Gees]

Awww, thanks Dave! :c))) I thought it was a good one, but no one said a peep about it!

A guide.. hmmm... I dunno. That idea sat there for 9 days before anyone even acknowledged it. :cD

Good luck with yours! Please let me know how you make out, wouldja? :c)

[i_am_dave]

9 days? I'm going to have to start looking at the dates on these threads.
I'll let you know how it works out. Should be really nice.

thx a lot for the help guys - it's working perfectly!!!
