60i to 30p at DVinfo.net

Jonathan Lutz · September 17th, 2004, 11:52 AM

We shot half of a show on the DVX100 (MiniDV) at 30p. Due to circumstances not worth going into, the show will be finished on Beta at 60i. What do I have to do in order to match the footage?
I understand that programs like CineMotion can convert it, correct?
Thanks.

Aren't you trying to go the other way around? Ie. 30p to 60i?
What NLE are you using? 30p can easily be mixed with 60i
footage and it shouldn't look *that* different on a *TV*.

30P will look quite different, rather like "frame mode" vs. interlaced. 30P's closer to 24P's look than it is to 60i.

But you can convert 60i footage to have a 30P feel just by de-interlacing it. You'll lose resolution, but you'll get the "feel" and it may intercut better.

Thanks.

We're definitely looking for a 'film' look. Simply deinterlacing 60i will save us time and money.

I suppose it's impossible to get anything at progressive quality from the 60i footage, though, eh? One of the ultimate destinations for this is the web, which is (one reason) why we went progressive to begin with.

I'm still curious about CineMotion and was hoping I'd have an excuse to get it. Will that do a better job than simply deinterlacing?

I have gotten quite successful results with a de-interlacing process I devised for Sony Vegas. Take a look at this article on my web-site:

You might be able to achieve the same results with your own tools.

you'll find discussion that uncompressed quicktime mov's actually have a "higher" resolution vs. uncompressed avi's - both come back into vegas comparably for the final step - but I can confirm that quicktime uncompressed intermediate is more aesthetically pleasing for final result than uncompressed avi - give it a shot!

all the best - thanks for your tips...

Mark, could you post more about the avi/quicktime quality difference, or point me in the direction of more info? Does this only affect uncompressed video?
