speed changes look strange

I'm using vegas 8. I'm working with footage shot with my HVX at 60p, when i speed up the footage to have it play back at real time (not slowmo) it looks stange, I speed it up to 250%. Should this be real time? It looks faster. I thought that 60p was 2.5x slower than real time. I'm working with a 24p timeline. Also the speed up footage looks a little strobe like. Is this a resampling issue? I'm using smart resampling now. thanks.
 
Did you shoot in 24p (recording mode) with a frame rate of 60p (scene file)? Or was it just 60p (recording mode)?

Also, are you bringing in the footage as an MXF or are you converting with Raylight?

speed..

yes, I shot at 24pn and used a scene file for the 60p. i'm using mxf files on the time line with raylight running in red mode.
 
Right-click on the clip in the media pool, and check its properties. If it says it's 29.97 or 59.94, then it's already at full speed -- speeding it up will make it faster and give you the results you see.
 
ok I think I got it..

So if I want to edit a clip and have it play at real time then at a certain point "ramp" down for slow motion I would have to shoot in 60P recording mode in order to get that silky smooth slow motion that i'm looking for?

The clip properties say that it's 23.976fps so I guess it makes sense now.
 
If it's 23.976, and you shot it with a frame rate of 60 fps, then it should play back as slo-mo. Speeding it up 2.5x SHOULD restore it to the "real-world" speed.

So, it might be a resample issue, as you touched upon. Try the different settings.
