Imported Video Plays in Slow Motion…why?
Hey Guys I hope you can help:
I set up a project with the following properties:
Sequence Preset: AJA IoHD 720p 23.98 Apple Pro Res 422 (HQ)
Capture Preset: AJA IoHD 720p 23.98 Apple Pro Res 422 (HQ) Varicam
Device Control Preset: AJA IoHD 720p 23.98 Sony VTROnce this is set up I import a video clip with the following properties:
Vid Rate: 23.98 fps
Frame Size: 1280 x 720
Compressor: Apple ProRes 422 (HQ)
Data Rate: 11.2 MB/sec
Pixel Aspect: SquareAfter I import the file, I drag it to the preview window and play it….the sound plays normally, but the video itself is playing in slow motion….THIS IS DRIVING ME NUTS. Can any of you shed any light on this???
I drag the file to the timelime (get no messages from the system) and play it from the timeline with the same results.

did they come off of P2 cards?
if so, see if remove duplicate frames is checked (preferences). I’ve had this unchecked and got very similar results as you’ve described.

All I can find in my USER PREFERENCES is on the TIMELINE OPTIONS tab. There is a check box that says SHOW DUPLICATE FRAMES and it is unchecked at the moment. Is there another place within the program that you are referring to?

This only comes into play if you’ve imported via “log and transfer” tool, and that is where you will see this preference. There is a “sprocket” that pulls down log and transfer preferences.
If you digitized footage, then this won’t help.
“Show duplicate frames” gives you color coding in the timeline when you have used footage elsewhere. I usually run with this checked, but I bet it slows performance a bit.
Let me know if this helps or not.

If this ends up being your problem, you will have to re-import your footage, with “remove duplicate frames” checked. I don’t have FCP open right now, so I may be slightly off on the wording, but its close enough that you should get it.
I think that some updates will default this preference to unchecked. Since I normally run with it checked, but have had the slow motion problem pop up, and when I looked at it….no check.
