# Scaling HD footage on SD Timeline

I don't have HD capabilities yet so I need to hear from those who do.

We all know that HD footage on a SD timeline needs to be scaled down to fit the frame, right? Otherwise, HD footage looks "zoomed in" on an SD timeline. How much scaling is required? 15%, 25%, 50%???

480/1080=0,4444444
• ###### 2. Re: Scaling HD footage on SD Timeline
Is that 44% or 4% or...? I'm not sure how to translate.
• ###### 3. Re: Scaling HD footage on SD Timeline
Try both.

I can't try it...I don't have HD. I'm relying on you guys to help me out. I know Steve knows the answer to this. Where's Steve when you really need him? :)

Did you flunk your math in school? 0,444444=44,4444%

Don't try. Think! :p

480 is in the neighborhood of half of 1080.
So, would you expect the percentage to be nearer to 5 or to 50 percent?

The problem has an uneven answer as you have seen. Shrink it to 45% and you will only cut off a pixel or so.

To test this out for yourself, put a color matte (white) on the timeline first, then put HDV on track two and scale it to 44%, then 45%. You will see that 45% is the right answer.
