Is project best in Source or Target Resolution

Spirit of Eden wrote on 8/1/2014, 4:57 PM
Hi,

Source video = 1920x1080p
target = 1280x720p

If I edit at 1920x1080 then I can crop down as far as 1280x720 without losing any quality right ?

So for final render anything above 1280x720 is scales down, anything at 1280x720 is rendered 1:1 and anything below is scaled up.

Have I got this right ?

Cheers
P

Your Project dimensions do not affect the output resolution. Period.

You can set your project at source or output dimensions, depending on your need for smooth preview, or precise output preview, respectively.

Ah right. That's good to know and makes sense thanks

How about the scaling ? If I crop to 1280x720 and then render to 1280x720 does Vegas render at exact 1:1 ?

I'd heard somebody mention that one of the benefits of 4K is the ability to heavily crop without loss of quality when rendering to 1080p.

If you have 1920x1080 (or any other larger pixel dimension) source in a project that matches the source pixel dimensions and, in the Pan Crop window, you set the crop settings to 1280x720 like this:



then render to 1280x720, the result will match the selected pixels in the source 1:1. there will be no resizing.

Cropping is cropping.
Has absolutely nothing to do with scaling, which is another name for resizing.

Thats great - thanks for the help.

If you crop, you are removing the part of the pic that is outside your crop area. Only do this if you don't want the discarded portion.

If you render 1920 x 1080 to 1280 x 720, the whole pic gets scaled down to the new frame size.
