i am looking for an app or plugin

Celluloid or Ultimate S can both do this. But neither one is free. Both have 14 day trials though.

i used celluloid for my last project. if all i want to do is convert the video from 4:3 to 16:9 with no processes then all i have to buy is the $35 version?

Can't you do this in Vegas for free?
Bob.

how?

you should be able to import 4:3 into a 16:9 project and then just render

wouldn't that strech the video? or can can you cut/crop it. rather cut top off and bottom off

That's correct, you just need the licensed version of Celluloid or Ultimate S to do this.
You can do it for free in Vegas, all we do with Celluloid is call forth tools that are already there, and apply them as they need to be. Celluloid just saves a lot of time.

kool. so just buy the basic version, or can i use it after trial ends? no comprendo por favor?????

If you want to do it for free do the following:

Set your project format to DV Widescreen.

Go to the Vegas timeline, select the framing on each clip, right click on it and select "match output format. Vegas will do the rest. The problem is that you need to do this on each clip. Celluloid or Ultimate-S will do all your clips at once.

You could also render the whole thing as a single 4:3 clip, start a new Widescreen project, import that clip, select the framing, rightclick and select "match output format". The problem is that things like titles and animated photos won't look as good as if they were rendered directly to the widescreen format.

What I do is edit the project like it is a 4:3 project. After I'm done I render it as a 4:3 project and use that render as the "fullscreen" option on my final DVD.

Next I use the Ultimate-S plugin to change the format to 16:9. I go through all the clips and tweak their vertical position. Then I go through any photo and title animations and optimize them for the 16:9 format. When this 16:9 version is tweaked as best it can be, I render the "widescreen" version that I will use on the final DVD. If the video is too long to include both formats on a single disk, I make separate "widescreen" and "standard screen" versions.

It really works well. You end up with versions that will fill the screen of either a 16:9 or 4:3 televison. If you view the 16:9 version on a 4:3 TV, it will look exactly like a letterbox render. The doubled lines are dropped by the DVD player. The 16:9 version has some line doubling on widescreen TV, but the horizontal lines are more tightly spaced than the vertical ones and it really doesn't bad. Not as sharp as a true 16:9 capture, but no worse than a the fake stretch mode found on cameras like the DVX-100 which essentially is the same thing.

i compendo. thanx spot. you are one kick but dude. YOU ROCK!!!!!!!!!!!!!!!!!!!!!!!!!!!

i take dj's 1 hour mix sets and create a semi-professional surround sound dvd with visuals

For best results nothing beats starting with a native 16:9 camera!
Think FX1 / Z1, they do shoot DV25 quite nicely.
Bob.

will celluloid allow me to tweak the verticle or do i need ultimate-s to do that?

Both Celluloid and Ultimate-S will just center all the converted clips vertically. You have to tweak them manually regardless. It's still a real timesaver though.

you tweak them through vegas or celluloid?
