C100: Identifying 50i footage in Premiere Pro

[mtnski]

I've been shooting a few clips in 50i for slow motion purposes. I then drop the clips on a 25P timeline and slow down to 50%.
When looking at the clip properties they show 25 fps. Is there an easy way to differentiate between the 50i clips the the rest of my 25PF clips imported from the same card?

I'm in NTSC land, and I asked the same question. How do I tell 30p footage from 60i footage in Premiere? There doesn't seem to be an easy way. Options I've come up with are:

-Mark the footage somehow, like on a slate or by actually saying out loud what rate you're shooting at.
-Watch the footage in question in a player that will show the interlacing artifacts of the interlaced footage (like VLC), and make a note of the filename.

Alarms go off reading this. Does this work well for you?

Is Premiere smart enough to refer back to the interlaced fields to build new frames when you slow your progressive timeline down? I wouldn't have counted on it.

The right approach would seem to be: keep clips in a 50i timeline, slow that down, and then export to 25p?

Funny thing is... A very old version of Premiere was smart enough. Premiere 6.0 from 2001. It would deinterlace interlaced footage and slow it down properly. I did a lot of action homevideos ten years ago with that thing with loads of slowmotions. Imagine my horror when I started using FCP and that couldn't do it. But for some strange reason that capability disappeared from the CS versions too and then I had to use AE. Maybe it's back in CC?

It doesn't even need to be that smart. Just take a look at the file, if it's 50i then do a bob-deinterlace and you and up with 50 frames. Drop those to half. Easy. For some completely odd reason several software suites did it like this: Deinterlace by dropping half the frames, then slow down. So instead of using 50 frames they first drop half of those to 25, then drop to 12.5. Really dumb.

Seems to be working. There are a number of posts on here with people getting good results with this approach.
