grrrrr... 30p

[azmyth]

I double checked my camera to make sure we were shooting in 23.976

I didn't run the camera, but i set it up..

just noticed all the clips from the first scene of my new feature are all in 30p..

What do I do? reshoot? (not likely) convert to 23.976 somehow? or leave it 30p and shoot the rest in 23.976 and mix them?

[cgbier]

You still have access to Final Cut? Cinema Tools can make 24p out of it.

[azmyth]

Nope any way to do it on pc?

[racer-x]

You can slow the video and audio 20%. You can also use frame interpolation to get smooth 24p, but it won't be as clean as slowing the framerate of the video and audio........

This would be easy to do in Vegas, I actually made a custom script just for that purpose.

[azmyth]

do tell

[racer-x]

This site won't allow to upload zip file, so you'll have to copy and paste all data in the code box into NOTEPAD and save as "Slow 30p - 24p.cs". Now place it into your "Script Menu" folder located in your Vegas installed directory. It should then show up as one of your script options in Vegas.

Add your 30p and 24p footage into your Vegas 24p project timeline and run this script. It will only effect 29.97 fps clips. You will then notice that the 30p clips have a wavy line in them. This tells you they have been Time-Stretched. You'll have to drag the right edge to the right to expand to full amount because they will be truncated by default.

This script does two things. It disables Resampling and it sets playback rate for video/audio to .80 (only on 29.97 fps clips in the timeline).

Here is the code:

Frame interpolation will give you more natural movement. Slowing from 30 to 24fps wont look right for a cafe scene. Avisynth can do it.

[racer-x]

I agree 100%, it would depend on scene shot and results wanted. I would also recommend Avisynth for frame interpolation, though I'm not sure the OP is willing to learn it. That's why I posted the easier method..........

Here is an extreme example of slowing framerate. It's actually 60p slowed down to 24p in Vegas using one of my custom scripts: HX9V_60p.mp4 (25 mb)

....Oh and Khaver, thanks a lot for that Window Cropper Utility. I use it quite often in Virtualdub.
I used it extensively to crop 4:3 image sequences into 16:9 to make this great Space Video:

[Khaver]

You're welcome racer-x. I've noticed your eyeball over at videohelp.com.

I thought it would be easier to crop video using a target in the preview window.

[drapeama]

I'll have to check these scripts for sure!

[azmyth]

I did it with AE and Twixtor.. not sure if thats the best method or not.

[Khaver]

There are 2 tests to whether it worked good or not. First, if there's a lot of artifacts in moving objects it's not working good. And second, when you have a moving object in front of a static, complex background, if the background "ripples" as the object moves past then it's not doing a very good job. There are some avisynth scripts that protect against this by masking around the motion. You can also add different amounts of motion blur to help hide any artifacts introduced by the interpolation.

Avisynth has some powerful tools and they're free.

If you're happy with the results you got then that's all that counts.

[drapeama]

Avisynth has some powerful tools and they're free.

I second that. I like Avisynth just to resize and reencode videos, but there's a lot more to do with it...

Answer C. What's done is done and cannot be undone. Correct it and move forward.
