Vector paint is fine in terms of it not making multiple effect layers for each brush stroke, but when you’re painting with the vector brush it isn’t accurately showing you what you’re painting while your painting.
Looks like it has something to do with it being stretched to 1920. The HDV I get from Canon’s XLH1 is native 1440×1080. I’m guessing the XHA1 is the same…? Toggle the pixel aspect button in After Effects and see if it (the lines) goes away.
Depending on the project and the amount of footage, sometimes I’ll capture entire tapes and use media manager to erase the media I don’t want.
Here’s a good How-To for the media manager if you’re looking for a way to make it delete unwanted footage from a large clip and turn sub clips into master clips.
Nope, I can’t think of any examples, but I’d still like to know how to stop after effects from making a new effects layer every time I make a new paint stroke.
