Does the 301 provide pixel smoothing?

Nintendrew said the review unit "preserved" the source aspect ratio, like an NTSC 720x480 analog signal, but did not stretch it back to 4:3 like an analog CRT would. At least that's how he explained it. So he called them out on that. I suspect that his review was in part the reason for forcing 4:3. While that's better, I seriously doubt it can properly handle DTV 480p from the Dreamcast, Genesis 320x224 & other oddball resolutions that got cut off in the overscan.


I doubt the mCable will do any cropping.

Agreed on the aspect ratio feature. I am also skeptical of the unit's ability to properly recognise DTV and VESA. Of course, I won't pass judgement until I get one, but it seems unlikely.

Given the filtering the mCable has always used to market their product, I seriously doubt it will introduce shimmering or do simple "nearest neighbor" scaling that delivers wildly uneven "pixels".

I was really hoping the mClassic filtering would be subtle enough to upscale 720p or 960p to 1080p and leave the image with very little softening and without ringing. Although, I doubt it will.

Of course, I'll give it a go with 480p consoles and see what I think.

I doubt I'm going to like this one, but it's worth checking out for the $59.

For retro consoles, IDK. The point of upscaling is to get sharp pixels and/or less lag.
- Why add AA and undo the sharpening? Dither?
I had that idea with the mCable GE. I tried a clean digital signal from N64 via the ultraHDMI mod, turned VI Deblur on and removed the first pass of software AA by applying an IPS patch to the rom, then set it to output 480p so the mCable could apply the max AA/enhancement. So the cleanest possable n64 480p signal is passed to the mCable. I thought maybe this would be a good use case for the mCable. Instead of AA being compounded by the upscale, resulting in an even more smeared image onscreen, perhaps it could reapply the AA after the upscale and achieve a more desirable result. In short, the AA isn't enough to mask the dither when both passes are removed, but if you leave the software AA the dither is far less noticeable. The smear is back though. Basically the N64 is a dithered mess without AA and that's just what it is. The mCable can't fix that.

- As for any pre 480p consoles, I can't see this being of any benefit over the OSSC, which you'd need to convert component, SCART, or VGA consoles to HDMI in the first place. It will give 240p sources a perfect 5x integer scale for beautiful 1080p without the need for the mClassic. RetroTink2x on the other hand can accept component or composite sources and line double 240p -> 480p, which the mClassic can then upscale to 1080p with AA. A retrotink2x + mClassic will cost more than an OSSC, so I don't think that's really a viable alternative, but if you already have a retrotink, maybe the mClassic is more attractive than getting the OSSC. I could see that.

- What about Shimering artifacts?
That's a plausible use case for this. A proper integer upscale should prevent shimmering, but if you want to fill the vertical screen real estate then the AA might be enough to mask ununiform pixel height. 480p -> 1080p, might benefit from this. I tested Dreamcast on the mCable GE, it accepted DTV 480p and 2x 960p from the OSSC just fine, and upscaled to 1080p filling the vertical space, but it stretched to 16:9. Will mClassic's retro mode stretch to 4:3, which is a bit too narrow, or preserve the DTV ratio? Probably the former, but that's not the worst thing ever. I thought it looked quite good otherwise. The AA effect was best with 960p IMO. Going all the way from 480p was too soft. It would be nice to have screen shots or video to compare. I didn't notice shimmering, but I wasn't specifically looking for it. I was appalled by the 16:9 and looked no further. The mClassic might be worth another look in this use case. I could see it being used as an imperfect upgrade to just the OSSC. The combo doesn't come close to the DCHDMI, but the mClassic does more than just Dreamcast and will be easier to obtain, use, and install.

I could go ether way on it. I'm still on the fence for one at $80. I hesitated an lost out on the $59 opportunity. At that price, I feel it might just be worth it. I like that the mClassic does everything automatically, I just want more control. 3 selectible modes is a step in the right direction, and while not to the standard of an OSSC in terms of customization, might be worth it for ease of use. As it is, I could envision dedicating 480p and up consoles to an HDMI switch hooked up to the TV via the mClassic. Those consoles benefit more from soft edges, despite the image "enhancements".

the mClassic uses a video scaling engine. The engine is based on DVDO/ABT's VRS scaling used in their 4K Micro upscaling cable. There is no shimmering, no matter what input/output resolution combination.

The 4K micro/mini lagless as well?

I don't recall. Not completely I think (half a frame maybe?).

The iScan Micro is essentially lagless like the mCable. The Leo Bodnar confirmed it.

I couldn't get it to work with the OSSC at all. I seem to recall others having the same issue.

(I don't know about the Mini.)

They need to stop marketing this thing for switch and start focusing on 480p-720p content. That processing is already showing itself to be one hell of an upgrade in that area and they're not doing enough to demonstrate it.

At least it doesn't look to have the edge ringing like previous cables.

I'd be very interested if there was one of these developed with a 480p analogue for CRTs but that'll never happen. I'd also want to be able to turn off any contrast & sharpness 'enhancements'. It'd be great if the mclassic had some adjustability in that area - maybe on a future model.
