Ok i've got a problem, i'm filming a short in widescreen (squeeze mode)
but i accidentally recorded some stuff in fullscreen. anyone know what i should do to edit the fullscreen footage in the rest of the widescreen footage. do i need to add black bars or something ?
 
No, just import the full frame files into the widescreen project and scale it up. It's unfortunate, and you will loose quality, but it's the best option besides downscaling the rest of your footage to full frame (not recommended).

And, of course, pay attention while filming next time! ;)
 
you can get the same quality as squeeze mode

just enlarge it, and apply a sharpening effect

your camera basically does this too.
 
Except not. He doesn't have the extra data to make FS into WS. He has to zoom in. There is no other logical option. The sharpen effect will help but what he should be doing is nothing like what squeeze mode is.
 
if you say so,

i have done tests of my own with the dvx, shooting in letterbox, (4x3) and in its squeeze mode, compared the two when i uprezed the 4x3 to 16x9, and the quality was better.
 
DVX100 uses only the pixels in the centre of the sensor to shoot squeeze (less than 400 vertical). Camera then uprezzes vertically. Exactly the seme thing happens in the editor when you enlarge 4:3 frames in 16:9 project. Some people say this happens actually better in the editor than in-camera.

PaPa is 100% right.

If the camera used to shoot the video can shoot 16:9 "nativelly", i.e. with full vertical resolution from the sensor the above is not true of course.
 
thx that should indeed work. i really should've paid more attention but i had so many things on my mind i didn't notice it was on FS :D

You should give us a side by side. I don't really believe you.
 
Chris, why would the camera do the vertical resolution change on the fly better than the editor with more processing power? Why is it difficult to belive? They both do exactly the same thing.

Processing power has no place in this conversation. I shot some footage the other day where I forgot to turn on 16x9 on a DVX (simply coincidence). Here is the difference.

This is an image that was shot in squeeze 16x9:

This is a 4x3 letterboxed image scaled up to 16x9:

Shoot, I even turned on a sharpen effect. Guess what? No matter the processor (Mine's an Intel Quad Core Xeon at 3.0 what's yours?) you can't just make up data that isn't there and get a good image. It goes against every law concerning digital video.

Look at the example below. I pasted a letterboxed 4x3 (with the black bars cropped) video clip into a 16x9 project. Here is what that looks like.

The look at the actual image size side by side. How on God's green earth could you make a letterboxed 4x3 image look as good as a 16x9 image with it being so much smaller? That's why I want screenshots. I don't believe you. I have shown you why, now, please prove me wrong.

Because the fact is that with dvx100 the squeeze 16:9 is shot with the exact same camera sensor pixels which you can uprezz in the editor from the center portion of 4:3 frame. Exactly!

Squeeze: camera crops the 4:3 frame to 16:9 and uprezzes vertical pixel count to 480 (or 576 PAL) in-camera.

Editor: Editor crops the 4:3 frame to 16:9 and uprezzes vertical pixel count to 480 (or 576 PAL) in PC.

The amount of original information is EXACTLY identical in either case (This applies only to cameras with no native 16:9 sensora like dvx100).

The quality difference is not dependent of pocessing power, but the alorithm used, and some say editor have better algorithms. With "processing power" I meant better algorithms, sorry.

I am on vacation now, can do tests next week.
