HELP!! Replacing Video on A TV Screen

Well now I use a picture of an old TV that I got from google which looks pretty good. Just having a problem doing the zoom in effect thats about it.

well if your working at DV quality the picture will have to be pretty big to maintain the resolution when you scale it.

I dont know if you're getting it but I got a picture from google and I put in AE and using prerecorded footage that I have, I put it in the TV picture. I've done that but I can't do the zoom effect.

dude i get it the problem is if you got an image off google that is like 800x600 or whatever i doubt you found one that big... when you do the zoom the image is going to loose its integrity...

to do the zoom "effect" goto effects>perspective>basic 3d
and use the distance from image attribute it will give you proper 3d distortion instead of just scaling... this is all basic stuff you should already know

Alright I see, well let me try it out and I'll update you guys on what happens. Thanks.

best thing to do if you have any sort of image adjusting program is open it up in that and resize it to be a larger file like a higher resolution.

Thanks alot yes it did work with 3D Perspective effect. But one more question, how do I extend the clip because it seems the maximum AE can hold is 12 seconds of footage. Why? Another question how do I keep the footage in the TV image without adjusting it? Thanks alot guys.

uhh you have to adjust the composition duration (very Basic)

your other question i reccomend you use a technique compositors develop called nesting... if you put your footage and tv together in one composition then use another to scale the comp1 as a whole you wont need to adjust it will you?

thanks I'm sorry but I'm relatively new to AE the only other thing I did in AE were Gun flashes

yeah we all were there once i remember those days

well i suggest you do as many after effects tutorials you can find before you try and start asking how other things are done... once you know the program well enough you wont need to ask unless it is something you cant work out

if you just leave the tv off it should be nice and black... placing small white X's made with tape on each corner of the screen you can track each X of the corner and use them to transform video footage or whatever in the same perspective... with a higher than normal matte with some feather it could look totally real...

goto google and look up corner pin motion tracking and just use the technique i said above to get good track points or triangles work even better when you learn the motion tracking from some tutorials youll know how big and everything and it will be easy

ok well I'm finished with 1:44 of the video, just about 3 minutes more and I'm done. THanks for the Perspective effect idea it really worked well. THANKS SO MUCH! I wish I can put what I have done but seems I don't know how.
