Drop Frame TC in 59.94 timeline

[Jeremy Garchow]

FCP does not allow for DF content @ 720p60 (silly huh?)

You will have to do some careful math to determine how to get the Df length of your NDF sequence by using a tc calculator or copy/pasting your NDF into an SD DF sequence, note the time, add/subtract and reedit.

Yep..one of the silliest things about FCP and HD. Can’t figure out why they did that…because the tape formats allow for DF.

So yeah, we do our math…

I heard the reason why is because the actual SMPTE spec for HD does not include DF for 720p59.94. Also, DVCProHD (how FCP sidled into HD) doesn’t support it. So I guess that’s why it wasn’t in there from the beginning. Why it still hasn’t been added now that all the decks can do it, Avids can do it, and the networks request it is a mystery. I can only assume that the way the code was written it isn’t an easy change to make. But according to Walter who talked to an Apple Engineer at NAB it is coming in a FCP2 point upgrade.

Nah
SMPTE says progressive formats are supposed to be NDF.

Unfortunately for us the satellites are so old that they can only understand DF timecode

Likely excuse…it’s so silly it’s up in space and out of the atmosphere. So FCP is so new it only understands NDF? And SMPTE didn’t care about the satellite that was launched into space and how to retro fit it to today’s new formats? Panasonic seems to understand DF on 720p, how’d they skirt SMPTE?

Actually SMPTE is so old they did not change, it is a carry over from the first days of progressive for film. DF was for interlaced content, NDF was for progressive. Progressive is NDF for 23.98, 24, 25, no one thought about that when the format jumped to 60fps.

DF is not needed for digital transmission, there is not a worry about the audio bleeding into the video as both signals are sent discreet to the satellite.

FYI – the play/ record heads are physically slowed down to create 23.98 or 59.94, hence the reason HDCAM at 24p gets additional recording time on the tapes

when was the last time you tried to get some cable guy to your place to fix something?

Thanks for the history lesson, Gary. Much appreciated.

Tell me about it, that and it’s 1.2 million bucks a month to watch the Sopranos and have high speed internet at the same time.
