Strange frame rates
on Feb 23, 2007 at 4:44:02 pm

Can any one tell me why every clip I digitise through my Kona LH shows a framerate in Quicktime of 24 point something instead on the 25 fps it is meant to be
Both DVCProHD and Uncompressed are showing this and its slightly troubling.
FCP sees the frame rate as 25fps in the browser and is very happy but a certain grading package which shall remain nameless can't handle the discrepancy

The tapes fine - Its a Sony HDCam through my M2000p Sony Deck - It happens with every clip from every machine.

AH

the 2000 mmmm.....

if your working in 25 is the deck set correctly ( dumb question i know)
but this puppy has some really weird setups and maybe it is sending out DF time when it should not be.


this deck is the only hdcam deck that still sees beta Sp tapes correct and works with the older 1035 analog HD content. So
some of the functions were ment to be region specific.

this would not be a US deck in the EU would it.?
That P on the end of the name indicates it is a North American issue model

Check to see if the frame rate out is 25 as DF or NDF - 25 is a NDF format.

Try opening the offending clip in Cinema Tools, then conform it to the proper frame rate.

Since the clip actually is the proper frame rate, there will be no change to it, except the metadata that is causing Quicktime to report the wrong framerate will be fixed.

I had this happen a while back, and this fixed it for me.

Try it out and see.

Thanks - I can do a batch export but its a bit of an issue if theres 1500 clips!

If its any consolation, it only takes a few seconds, as it does not have to render anything. Its not actually changing anything except metadata.

Try it on one clip to see if it actually fixes your problem first.
