After several attempts, registration made!

FWIW I think you're best off just looking at the Dimo 4K Video Converter as just another video converter that comes with a downloader built in. That's good if you want or need one, or are just interested in trying out another converter. If you've had enough of this almost commodity [video converters] in a somewhat saturated market, then skip it.

A fast 56 MB download from the Valentines offer page [unless you're using Opera with its VPN], Dimo's 4K Video Converter is a video converter & downloader coupled with a utility that seems at a glance the same as scanTransfer [ scantransfer[.]net ] -- a sorta cute tool that by using a QR code seems to make it a slight bit quicker than transferring files from your phone/tablet to PC/laptop vs. using Dropbox or the cloud. The portable version of scanTransfer adds a folder with about 65 MB of files/folders, but monitored in a win7 32 bit VM, only adds event logs to Windows itself. That said, you'd probably want to make sure you used it on a secure home network without any connected devices that had already been compromised.

The 4k part IMHO is just to get people's attention. Ffmpeg, the core of most of these converters & rippers, has done 4k for a while now. The problem with down converting 4k video for most people as I see it is *Why*... If you could pop a 4k Blu-ray in a drive on your PC, & copy the video to your hard drive without DRM, that could make for really nice 1080p video. But right now that's an iffy, expensive proposition, not to mention any legal concerns.

The 4k streaming video that I've watched [from Amazon, Netflix etc.] doesn't really look that much better than streaming good to high quality 1080p, because they use so much video compression to get 4k to fit through the internet pipes. To me the 1080p Blu-ray of Valerian looks better than the 4k version streamed from Amazon video. Figure into the equation both the time to re-encode or convert -- while converting 1080p to DVD frame sizes takes minutes, encoding to 1080p takes hours -- and the quality loss you always get from re-encoding, and I personally don't see much benefit vs. just downloading the 1080p version in the first place.

So, ignoring as possible the maybe unfortunate marketing -- 4k plus the stretch of calling the utility a media server -- you're left with a video converter & downloader, which for many folks isn't really a bad thing.

Can only import and convert 4K video. No other quality is supported.

Yea, that's just what everybody needs........downscaling a video to a poorer quality, For TV, you need and Ultra 4k television, 4k ultra HDMI cables, and channels that are broadcast in Ultra HD. Directv only has 3 channels out of their line-up. For computers, you need 4K Ultra HD audio components. Only the newest computers have this capability. BTW, where do you download 4k videos?

not even barrel correction ? :/
