Scaling down Video

Postby Glitzer » Thu Mar 25, 2010 12:55 pm

I apologize is this is a noobish question, but I'm trying to mix 1080p and 720p footage together. My project settings in adobe premiere cs4 are for 720p. So my question is this, if I scale down the 1080p footage to about 70 (inside the program) so the whole thing fits right in with 720p, does the quality become worse than 720p? Or would it be better to not scale it and leave it nice and fat even though some stuff gets cut out. Just wondering what to do to preserve the most quality.

Thanks in advance!

The output quality of the 1080p scaled to 720p would be the same as if it were originally 720p. Pr does not use the preview window renders for final output, it uses the source. Unless your using the 1080p at full res for panning or zooming, just use rightclick-clip "Scale to Frame size".
However god/whatever deity/Anime character you worship have mercy on your exporting soul. CS4's AME run in x64 can't export seqs with more then 16GB of source without using Dynamic Link into AE. I suspect its a x64 compatibility thing.. SO GLAD x32 goes away in CS5.

Holy Mother of Moses that was a fast reply.

Thanks for your answer, it certainly relieved plenty of stress when I read it. Then I got to the second part, and my heart dropped. I actually I have x86 if that means anything. Also, not even running as administrator will solve the problem?! That's my last resort! I'll have to research this Dynamic Link if it's my only salvation. Once again, thanks!

I would suggest you to scale your 1080p footage in avisynth with
Code: Select all
spline36resize(1280,720)
as leaving big scale amounts to premiere will introduce some nasty aliasing or excessive blurriness.

So I decided to experiment with what you said mirkosp , I mean, could one little script function that you could do inside of the editing program make a difference? I assume aliasing is when the lines are waving and generally make blood shoot out of your eyes? Because that's what half my amv would of looked like without your script. UR MAH HERO!
