I am aware of the loss of resolution if I deinterlace. But I will gain non-blurred frames instead of two mixed fields per frame. If it looks terrible then nothing gained nothing lost. But I want to see it though.

If I have 1 second of 30i (480i) video, i want to end up with 60p (240p), perhap using a velocity envelope to "double" the speed back to normal.

I did a search for 60p, 30i, progressive, etc. but didn't get any useful info on "How-To"

Thanks

I want to separate the the upper/lower fields of 30i into individual frames. In other words, 60 frames per second non-interlaced. That would inherently make the resolution 240 because fields are 240...right?

I want to separate the upper and lower fields into individual frames.

I'm sure 30i is the best-looking..that is why cameras operate that way. But, I want to see the individual fields of 30i in succession (240/60p)...not blended (480/30i)

An interesting idea, I'd actually thought about trying this myself, simply to get double the temporal resolution at the expense of vertical resolution, simply as a poor mans high speed camera.

But how to do this I don't really know. I'd imagine something like AVISynth might have a way of doing that.
If you only wanted to do this for a few frames you could do it by hand like this.
Save a frame as a PNG. Open that it PS, use de-interlaced filter, first on even field, save as PNG, the use odd field, save as .png. Go to next fram in Vegas and repeat. Then bring those still images back into the vegas T/L , set project properties to 60 fps progressive.

Bit tedious for more than a few frames. I think though there's a script to export from the T/L as a image sequence. Then maybe you can do a batch convert in PS to handle the odd/even splitting.

Hope this gives you some ideas. Also investigate VirtualDub and AVISynth.

OK, this looks more complicated than I thought. Vegas doesn't do any of this natively?

Not that I can think of, I mean it's not exactly the sort of thing that there's much call for. As a matter of interest why do you want to do this?

I mean you may not fully understand what the results will be. From my understanding of how cameras shoot interlaced images it's not quite as simple as just two half res fields. Depending on the camera there is actually some interaction between the fields i.e. some of the color information is split over the two fields so you nay end up with some really horrible stuff once you split the fields out.

Most reliable way is to shoot with a progressive scan camera at 60p. This gives not only better temoral resolution but also increases the vertical resolution by 29%.

farss is right, there is a plugin for VirtualDub that can do this, but VirtualDub can only seperate the fields on MJPEGs. That's why you would need AVISynth as well. Can't remember the name of the plugin, sorry.

I tried it once, and while the slow-mo was impressive, there was a slight flicker between each frame even though the plugin moves one field up half a pixel and the other field down half a pixel to compensate.
