1080 60i to 1080 50i HDV

Hi, i have some footage that has been shot with a z1 that is 1080 60i. i need to get it to 1080 50i so i can mix it with other footage i have. does anyone have any idea how i can do this? i have tried using cinema tools but it wont give me the option to conform.

im running a mac with FCP 5HD, Cinema tools, After effects

www.nattress.com tools or if you're skint, JESdeinterlacer 2.7 - Nattress standards conversion will do it on the FCP timeline, JES would render out a file from the source clip that you'd then have to import into FCP.

I believe FCP has a standard converter inside, but it's not very good.

That's pretty much it, Dylan. If you want to slow things down, you can use Cinema Tools to conform, but not on native HDV footage - you have to use it with an edit friendly codec.

Standards Conversion works pretty darn good on HDV. If you want to try it, I'd change the motion blur setting to 15% for NTSC to PAL conversions to maximise resolution.

I have to admit I've never tried Standards Conversion myself, never having needed to go to NTSC - but its reputation precedes it.

I wasn't aware Cinema tools could go from 60i<>50i I thought it just did 25<>24 and 24pA pulldown removal.

Conforming 60i to 50i would involve slowing down the footage about 15% wouldn't it? far too much for standards conversion I would have thought.*

Do you mean compressor can handle standards conversion? Again I've not tried either - not having had the need.

*hmmm, re-reading I realise maybe that's exactly what you mean when you say "slow things down"... I assumed you were referring to Cinema Tool's and Compressor's rather sluggish reputation.

CT can "conform" from one frame rate to another, so you could go 60i to 50i by slowing down from 29.97fps to 25fps. Everything would be slow, but it would be a very good conversion otherwise! If you're using footage on a documentary without sync sound, it can work very well indeed.
