Upscaling video in VS7

HI

Corel advertise -

"Enjoy new performance gains with the ability to upscale HD to 4K"

Just curious if anyone has tried this and if so what was the results?
cheers

You could just do a 5 minute clip and judge for yourself, then perhaps you could tell us about the result.

I think part of the problem might be how you go about judging the result. Few of us -- if any -- would currently have 4K-capable TVs, though I suppose one or two might have computer monitors that might have that capability. I just don't know -- do such monitors even exist? But playing any 4K video on a monitor with 1920 x 1080 or less resolution is unlikely to be able to tell you much visually about what you have produced. Sounds like marketing hype to me aimed at a future audience...

I have, in any case, just rendered a short (22 second) HD file (mp4/h.264, fully progressive 50 fps, bitrate 29 Mbps) to a Custom 4K file using two pass encode to maximise quality. My monitor is a 24" Acer 1920 x 1080. Playing back the new video in X7 simply showed as good a quality as the original, though curiously, the 4K video on the preview screen was clearly smaller in format size than the original. I can't account for that. But after that, I could not find anything among my software players that would play the 4K. VLC (recently updated to latest version) started off OK and quality looked good, but then playback got erratic and after a few seconds the video playback froze, though the audio continued. Needless to say, the original HD video plays perfectly well throughout.

I dont have a 4k TV/monitor which is why I asked the question

Any upscaling will lead to quality loss, same as going from SD to HD.
I've not got a 4k tv, but I've looked at 4k conversions from VS and on my monitor, as per Ken's views, it looks ok, but is no real taste.
