You can simply set 25fps as the output frame rate when you Render the file. However, especially if you're using Interlaced video, I find that Vegas' frame rate conversion isn't as good as other programs out there. Both Grass Valley Procoder on Windows and Apple Compressor on the Mac (not my favourite system, but never mind) can produce superior frame rate conversions, if you have access to either.

Thanx Lyris, but I was more hoping to actually bring the 30 fps footage back to 25 fps by changing the playback speed, turning it into 25 fps so to speak without doing a frame rate conversion.

Farss said something about avoiding resampling, I'm just not sure how to do that.
The plan is to crank the movement in front of the camera up and then bring the playback speed back from 30 to 25 fps. I'm just not sure if my way to do that is right:

- import the cranked up 30 fps movie files
- slow the playback in the timeline down to 25 fps by changing the playback rate in the properties of the track....
- Render the project at 25 fps

To be honest I think I am doing this the wrong way since I already convert the Canon files from 30 fps to 29,970 fps making intermediate files to be able to work with them. 30 fps simple can't be chosen as an option for Sony MXF files.
Does this small difference in fps make a huge difference in output, or is this near enough not to cause trouble?

Maybe there is a better way to do it without resampling the footage?

To put it a bit differently: If you had Canon 5D MOV files of 30 fps and had to make intermediate files to work with and render it to 25 fps output, what would be your workstream, considering the fact that speeding up the camera action and slowing down the footage during the process is part of the deal?
