Used a new template but no luck.
So I loaded a smaller video (480 x 360) and ran my current template on it (which is set to render at 640 x 480) and it came out 640 x 480. Changed the setting to “same as source” and it stayed at 480 x 360.
Yet, when using the original 640 x 480 AVI, it comes out 638 x 480. Argh!
BTW – thanks for your help with this!
