Changing the Canvas Size of a video...

[Jaxel]

Okay... I dunno if this is possible... Lets say I have a 640x400 movie... I would like to increase the canvas size and add 80 pixels of black to the bottom of the video to make it 640x480. This is NOT resizing, this is increasing the canvas size within the video much like increasing the canvas size in Adobe Photoshop. Basically I want to add a small black bar at the bottom of the video where I can put in text information without distoring the original source video.

Is this at all possible in VDM or AviSynth?

AviSynth's addborders() will do what you want.

In VirtualDub, you can add the resize filter (retaining original picture size) with letterboxing to make black bars at the top and bottom and then follow it with a null transform filter set to crop away the top black bar.

Sweet, that kicks ass... thanks... but I got another question...

I have a logo... and I want it to fade in and out once every 30 seconds... I dont want to have to add in 10 logo effects, I want to be able to do it with a single logo filter... have there been any filters created with this ability?

Not in VirtualDub. You can probably cobble together an Avisynth script to do it.

Please refrain from profanity in your posts. Thank you.

And why do you want to add borders to the video if I may ask?
