How will you be delivering the end product? HD or SD?
If SD; I would convert all the HD to SD; its the same aspect ratio and will work well.
If HD, Dont try upscaling SD it will look terrible. Perhaps use the SD shots as PIP or matted shots over the main HD footage. Im guessing the SD clips would be Broll material?
Downscaling is a far better option than upscaling.
I think that is the first time I ever answered faster than lightning fast HARM. This is my lucky day; I think I'll go buy a lottery ticket!
I have never beaten him, though I do try often. Job well done!
Now, if that lottery ticket is the big winner, the forum will suffer, as you head off to spend your $'s.
PS - I agree with you both.
Have you ever tried Red Giant's Magic Bullet Instant HD (advanced)?
I hear it does not do a bad job.
I have not. I poke around at it.
Or Dan Isaacs' sd2hd?
(No, that's not a typo)
Never tried that, but i will give it a spin some day.
