where can I learn about keeping compression settings within standards?

February 17, 2012 at 6:47 pmI tried changing the frame size and they noticed immediately. If I am able to create the powerpoint, I agree because then I can just scale it. In fact, half of the video I’m working on now was recorded at 480i and I have it stretched up to 720 and no one noticed.
Now if you have some trick that I can save it at something smaller like 480×960 then have the codec tell the player what size to stretch too, I’m all ears. The only time I’ve gotten away with that is by providing the slide, or embedding it in a webpage For them. Something like that. When the deliverable is a straight video I’m stuck with the size they ask for. I’ve already told them they won’t notice a quality change from 1080 to 720. 90% of the time I wouldn’t even notice on a large screen either unless they are played back to back.
I’ll give the profile 8 a try next time and see how that fairs at lower bitrates. If they don’t care about size I just check the 720p HQ and render. Done! Sure it’s a 500MB presentation, but that’s why you have that 3TB hard drive on your desk. haha

February 17, 2012 at 7:25 pmOops, mistype. Thanks for the correction on profile. It’s confusing because it says “advanced profile” for 9-advanced. I know they are different codecs though.
And that should have been written, When they don’t care about size. Occasionally they don’t, so I give them high quality. I usually take it down a little bit just to make sure it’s not so insanely high that their drives can’t keep up. Plus, in case someone plays it off of a network drive then it needs to keep up too. But I’ve found the preset for 720p HQ works great in those cases. The audio is usually way overkill for what I’ve got, but I’d rather not mess anything up since it’s seems finicky sometimes.
I’m more concerned about the Premiere bug I’ve just encountered now though.
