Yeppers. That's the beauty of these different methods, they can easily be converted to other display methods. I do know for a fact that 3D content can be scaled, as I have quite a few 3D 720p samples, and they look fine scaled to 1080p. I also have samples using the interlaced method (Sensio), and those are converted and scaled fine to 1080p.
There hasn't been a method yet that Stereoscopic Player hasn't been able to convert. Nice piece of software indeed.
Yes, but your Stereoscopic Player is not just a scaler, it is also a 3D reformatter.
Generally, 3D formats where the left and right images are interleaved at a frame level, such as side-by-side, top-bottom and frame sequential, can survive scaling operations and compression.
Pixel-level interleaved formats, such as line interleaved, column interleaved, and checkerboard, can not be scaled and won't survive a 4:4:4 to 4:2:0 transformation. They require to split the 3D signal into two separate 2D images, scale them independently, and then re-assemble them again into a 3D format.
Such a format conversion will result in the artifacts of both 3D formats being present in the output signal. If you convert from a side-by-side signal (half horizontal res) to a top-bottom or line interleaved (half vertical), then you will end up with a quarter of your original resolution, half horizontal and half vertical.
Conversion to and from frame packing or frame sequential (full) won't introduce any additional artifacts, since those formats don't degrade the resolution or frame rate.
This also goes for your 720p SBS to 1080p SBS conversion, which is a simple scaling operation without reformatting. Since both are horizontally challenged, you won't have any additional degradations.
