1080 59.94i to 1080 23.98P >What's the best route ?

I have some material shot at 59.94i with a Sony f950 and recorded on HDCAM which I'd like to have
converted to 23.98P. Can anyone offer suggestions on the highest quality way to do it ?
I'm thinking maybe the Snell & Wilcox Alchemist box, but would like to hear other suggestions.

thanks,

I believe that Final Cut Pro's Cinema Tools or a high end Avid can do this.

Thanks Steve,

Well Cinema Tools will do reverse telecine, but that only helps if you're dealing with 59.94i
HD that contains film footage that was telecined and had 3:2 pulldown added. It won't really
convert 59.94i originated material to 24P. I have about 22 hours of material to convert, so doing it
through software conversion would take forever anyway....

I guess I should have said "Does anyone have any suggestions for real-time hardware based
solutions for converting 59.94i HDCAM footage to 23.98P HDCAM footage".....but I wasn't thinking.

Any takers ???

Steve,
We use the S&W Ukon, to do this sort of conversions with much success, we've used it recently on a couple of high profile projects. Unfortunately the Alchemist won't support this in HD (all it's inputs are SD, it can upconvert but not cross convert HD). We also have a Teranex box in house, the Ukon is defeniatly better. If you'd like a quote drop me an e-mail at js(at)grsv.com.

The Teranex format converter can do the conversion.

One question why did you shoot 59.94i in the first place with the F950? Was it because you wanted to reduce the motion blur in 24P?

I assume you were shooting in HDCAM SR?

Hi Tony,

No, we shot it in 4:2:2 and recorded to HDCAM with a client-supplied deck (HDW-250)
which only does 59.94i. Now we're re-purposing the tapes and want to convert the whole batch
to 24p. Would the Terranex give really good results ? I'm still concerned about de-interlacing
issues.

Wow what a bummer,


You should have cross converted to 1080 60i with a 3:2 puildown and recorded that to the HDW-250 then later reverse out the 3:2 pulldown to extract the native 24P.

Yep, that's how I told them to shoot it in the first place....but the client had other ideas.
Now that they've figured it out, I'm being called on to rescue them.......

thanks for the input...
