Slo-mo

I've searched, and read a few threads about using FCP and Cinema Tools to do slow motion from 60i footage, then drop it into a 24p timeline, and people seem to like it. I've been using Avid Xpress Pro at home, and have been shooting 24pa footage, and am looking to do good slo-mo. I guess I'm looking for a shortcut, but if I need to buy more software, then so be it.

Any ideas?
 
Not easy task to make slo-mo from progressive footage. I've tried ReTimer for this. It creates in-between frames using existing frames. Very slow and not good at all, if there's fast movements in footage. Avid's own acceptable thing is 50% slo-mo from 60i, and no decent avx plugin for this as far as I know.
 
One way is to shoot 30p with the DVX100 and capture it in a 23.976p project with the NONE set for pulldown in the Film/24p settings. This will capture video only and play it back as 24fps (25% slow mo).

If you want to create 60i to 24p, you can capture the 60i material in a 30i project and create a 200& progressive render using FluidMotion. Then export video only as QT reference and import into your 23.976 project.

See whitepaper on frame rate conversions on my website at:

I will create a preset for 30i - 60p and add it to the web page.

Thanks guys,

My footage is shot already (in Hawaii, and although I'd love to go back, I can't). It's 24pa, and there's nothing I can do to change that fact. Should I just go with 50%, or whatever looks best? I'll check out ReTimer, Sebastian, thank you for the reply, but if you give it a thumbs-down, then maybe I'll just keep looking.

Any other secrets/tricks-of-the-trade out there?
 
There is a way to do it for 60i...Ask Barry Green...He has the formula for slow mo for the DVX and what to do in post to get the right effect. Or you can get the book from Barry Green.
 
I have the book at home, but haven't cracked it in awhile. I'll try next time with 60i, but I was planning to do a progressive 24p DVD, so that's why all the footage is in 24pa.

Which brings up a good point: If you're using Avid Xpress Pro, and try to digitize into 23.976 project, you get a big red message warning you that the only material that that project will support is material shot at 23.976, which is why I shot my project in 24pa.

So how do you get 60i material accepted into a 24p timeline?

And while I'm on the subject, if you try to tweak the new project settings for a 24p project, you have a dropdown menu that lists 2:3:2:3, but when digitizing, you get the message that I wrote above.

WHat gives?
 
I believe with avid you will need a mojo in order to see it in realtime. Versus a program like Vegas that will accept 60i and be able to put it into a 24pa timeline without the need of external equipment like the Mojo. Even though 24pa material is really 60i but is encoded with the 2:3:3:2 codec to be recognized when you put it into 24pa timeline.
 
Gotcha...................I think.

I don't like shooting in 60i, I bought the camera because I wanted to get away from standard video, but I'll try it next time.
 
if you're happy with avid on a pc, would you mind if I ask what configuration of pc are you running on? i mean is it AMD 64 with sata 7200rpm drives with 3 gig of ram, a million gig of hard drive space. I want to set up something, but would like confirmation from a happy user. thanks in advance for considering my request !
 
I'm using dual 3 Xeon processors, with a gig of RAM, and 240 gigs of storage. I haven't upgraded anything yet, but it runs pretty smooth and fast. If you're planning on 3 gigs of RAM, it couldn't hurt. I hear that the Avid Mojo is RAM-hungry, so you may want to check that out.

Then again, I'm a better photographer than I am an engineer, so I'm definitely not the expert in this arena, but to answer your question, I like Avid just fine.
 
I'm running an Intel P4 2.2ghz processor, 1gig ram (just upgraded from 512MB), and about 1 terabyte of storage... Avid runs fine for me... ran fine even before the RAM upgrade (no Mojo).
