Hi,
 
Using SONAR Platinum and it's up to date. All external analysis (G-Spot / Handbrake) of a video file I am using shows a frame rate of 23.976 - a standard rate. This is also the stated frame rate from the video producer. 
 
I have set SONAR to this frame rate (Preferences > Clock). I am syncing to audio which is at 48khz and my bit depth is also 48khz. Yet the Media Foundation information in Video Properties shows a frame rate of 23.968 - which (in my experience) is an odd rate.
 
Any idea what might be going on?
 
There is a "burned in" timecode window in the video which is usually within one frame of the running timing if not right on the money, but the odd frame rate (23.968) bugs me.
 
All ideas appreciated.

I'm not a "tech" expert, but I have worked with frame rates in various forms for decades.  If your burnt in timecode is as you say,  you are good to go and I would not worry about anything.  Frame rates use to be actual, physical frames that would pass a light in a projector.  Then video came along and fields (1/2 a frame) came into a play. Now with computers where one "picture" or frame starts or stops varies with codecs.  That is why you will see the burnt in Time code off or not match a frame or 2 every once in a while.  Who's to say the burnt in Time code is accurate or the computer you are working on has the correct frame. 
 
I've worked on a million projects with Timecode and sync, and when I have timecode that matches like yours...I spit out a .wav or an OMF to mix and no one complains about my sync.  In fact, because i use a "2" beep and document my sympte start times I usually get complimented on my sync.
 
In short, you are good to go.
 
Good Luck!  Have fun!

Hi Jimbo,
 
Yeah, that's sorta what I figured. My timings have worked out just fine and I appreciate you taking the time to set my mind at ease!
 
Cheers!
