Understanding How Slow Motion Affects Frame Rate

7isMagic wrote on 8/11/2012, 10:39 PM
First and foremost, I am new to Vegas Movie Studio 11.0, I've much yet to learn (so please be patient with me)... :-)

I've run into one specific problem and I'm hoping someone might be able to help me understand why it is happening and if it can be fixed.

I'm using video game footage in my current project. All the footage has been recorded at the same frame rate. I have noticed a problem, however, when I slow down specific (individual) pieces of video (when I "stretch the video" in the timeline by grabbing onto it and holding down the CTRL key).

Oftentimes the slow motion pieces of video become distorted with a kind of "ghostly" image superimposed over it. Is this happening because the frame rate for a slo mo piece of footage is different than one that runs at a regular speed? If so, is there any way to compensate for this, so as to avoid distortion?

Or is there another reason this is happening (which may have nothing to do with frame rate)?

Thank you in advance for your help

Right-click on your video event and Disable Resample.

Esp. with your game footage, there will be some slight stutter as Vegas duplicates or drops frames to compensate.

Thank you, musicvid, for your recommendation. It was very helpful.

I noticed there is a way to turn off (by default) resampling of the entire project. (Edit-Switches-Disable Resampling in the pull-down menu).

But will this affect both video AND AUDIO resampling throughout (and as such, it would be best if I disable resampling for individual video events as suggested previously).

I'm also wondering under what circumstances should "Smart Resample" or "Force Resample" be selected by default for a project?

Disable Resample cannot be set globally. It's a per-clip option. If you don't have one or more clips selected, the resample options do not light up on the pulldown.

Smart Resample is the default.

There's a group of us sort of petitioning Sony to create a user-selectable setting to have disable resample be the default if we wish. Feel free to join in.

I think there's a script for that: unfortunately only available for Vegas Pro.

Thanks to everyone for your guidance and feedback. It is MUCH appreciated! :-)

Chienworks mentioned there is a group petitioning Sony to make "Disable Resample" the default. I'd be more than happy to join in - what do I need to do to add my voice to the group?

Cheers!
