Feelworld LIVEPRO L1 Multi-Format Video Mixer 4 x HDMI Inputs,2" TFT Display,Live Streaming,Remote Controlling by PC/Samrt Phone(APP)

I'll be as detailed as I possibly can. Short answer. If you want an HDMI video mixer and cannot afford a Roland or even a used BlackMagic Design (BMD) mixer, then this is the only option I'm aware of. So buy it, but if I had the option, I'd take the roland 2 channel or BMD mixer over this.Pros:- Accepts a wide range of video inputs, outputs as high as 1080p60 (I tested, it's accurate).- Switches between 4 different HDMI inputs, and scales them to output resolution.- LCD Preview screen is a welcomed addition.- USB 3.0 UVC device capture.- LAN port for ethernet control (limited use case for most, but if you have PTZ cameras, this might be desirable).- No internal fan, no noise! (The Roland is loud by comparison).- Solid exterior construction.Cons:- While the screw in DC power connector is awesome, mine did not sit in tight enough, giving me a false sense of security. There's no power button on this device. And even with the barrel connector screwed all the way in, I was able to wiggle the cable a mm or so which caused the device to power off.- The LCD interface uses a light blue color (over top of a white color) to indicate you've selected a specific FX or PIP mode. Who in their right might would think this was a good color combination? You can't see what you've selected. Even with good eye sight. Hopefully they update their device and change the color to red or green, or anything, but light blue.- The slider is going to break. Trust me, I've handled (and mishandled) dozens of midi controllers and I know a flimsy slider when I felt it. Additionally, if I moved to fast (or erratic) the slider didn't pick up the position change. There were plenty of times I slide the slider 100% across to its limit, but the visuals only showed a 90% transition. Id then have the flick it back and forth quickly for it to move forward the final 10%. Needless to say, the slider position is not accurate.- Delay. There is a noticeable delay between crossfades, and even more so with other built-in FX. What ever processor they used to handle the video blending is slow in comparison to other brands. But if you're ok with an almost 100ms delay (depending on the FX), then go for it. Like I said, there are few options on the market that do this and at such a low price, it's hard to compete with.- There was a screw inside my case that was lose. The packaging it arrived in was pre-opened despite it being a new unit. As for quality control (idk)...- No internal fan? I like the idea of this, but it makes me wonder why Roland would have a loud fan in theirs? Will this video mix pass an endurance test? Is the weaker performance keeping it cooler? Only time will tell, but I'm returning this one.- Buttons do not always register press. Fine, you'll just have to hit it twice.-No separate HDMI for the Preview Output. There's a preview monitor mode, but unless you buy two of these it won't do you much good. Roland has a dedicated HDMI output for preview that can also act as an HDMI splitter.All in all, I'd buy this if I needed it and didn't have the money to buy a Roland or BMD. I'm definitely keeping an eye out to see if they make a newer version that fixes some of these issues. Or by then, maybe Roland will bring their price down and BMD will add a small LCD and fader to their mixer?Who knows, but I hope this review helps. (Too bad they made 30 different listings of the same device).

I initially had an issue where the entire case seemed to be carrying a voltage... well... I discovered the outlet I had plugged my PC into wasn't properly grounded so the USB ground was floating and when I had the switcher plugged in via USB that floating ground was grounded to the unit's case and then through me into the actual earth ground of my basement work room's floor. Oops! Once I cleared that up the issue went away.Aside from that, though, it's excellent. The t-bar movement is smooth and pretty accurate, the menu structure is usable (although a little confusing at first), and it works perfectly as advertised. I've been super happy with it.Before I bought it I was wondering about the t-bar operation though, so I thought I'd post clarification in case anyone (like me) wonders the same thing:If you stop moving the t-bar at any point in its travel the video will hold in that state, ie if you have it set to a crossfade effect and stop the t-bar in the middle your output will be the two video sources superimposed on each other with the "new" source being somewhat transparent. The earlier you stop the more transparent the new source will be. It will happily hold in this state indefinitely, and you can either complete the movement of the t-bar to switch source entirely or go backwards and return to the original source only. You can't change the selected sources until the t-bar is completely on one side or another (as expected) but you CAN use this to do a video-on-video type effect without any trouble.

I've replaced my ATEM Mini and love it. It's built metal solid, love the T-bar and simple to use. Plug n play. It does run a bit hot.

Software update link did not work. If you are willing to forgo the so-called update then this is definitely worth the money. I could not rate higher because of the cumbersome software.

Buen producto, a diferencia de la competencia como lo es Blackmagic el livepro L1 tiene una pequeña pantalla donde puedes monitorear las 4 entradas HDMI que está saliendo al aire. Eso marca la diferencia.
