    Datavideo DAC-70 reviews

    DAC-70 SD/HD/3G-SDI Up/Down/Cross Converter is rated 4.7 out of 5 by 24.
    Rated 5 out of 5 by from Excellent Converter The Blackmagic video switcher can be quite picky about the input resolutions and frame rates so this was our solution. Although we only just received this unit so far it has been very simple to take a laptop VGA signal and scale it to a 1080p SDI for the Blackmagic. Perfect for our needs. The unit is very robust looking, with resolutions easily controlled by dip switch. It is a little bit of a nuisance to have to look at the bottom of the unit to see the dip switch settings, but if that's all I have to complain about then its pretty good!!!!

    Rated 5 out of 5 by from Solved all my BMD ATEM 1 M/E problems Just set up my new workflow with a BlackMagicDesign ATEM 1 M/E Switcher. I brutally realized that I couldn't bring in HDMI from a Retina MacBook Pro, nor HDMI from an Apple TV (to use for convenient wireless airplay for presenters during recordings). I spent the weekend doing all the research I could to find solutions. I decided on this Datavideo scaler. It solved all my problems! Changing my HDMI output resolution via the software SwitchResX on my mac allowed me to bring a Mac directly into the ATEM without a scaler, BUT this allows me to do it with anyone's computer without the need for special software. AND it also made the Apple TV work great (set it to 1080p) AND I can now also bring in additional computers via VGA if I need to, which is awesome when I'm recording someone with a random computer of their own. I testes the VGA with a Mac (Thunderbolt adapter) and a slightly older Windows PC. Both worked perfectly, both with 4:3 and 16:9 presentations, no distortion in the picture that I could find. My workflow: I use an BMD ATEM 1 M/E Switcher with a production workflow of 1080i 59.64fps (limited to interlaced because of camera compatibility issues between the ATEM, a Sony FS700 and Canon C100). But now with the Datavideo scaler in this mix, this setup works flawlessly so far. Strongly recommend it!

    Rated 5 out of 5 by from Exceeded my expectations I usually buy AJA but this box piqued my interest - especially for $ less than AJA. I needed a UDC that would scale down a 1080i HDMI to 480i SD-SDI. This box was easy to use, highly functional with a many ins & outs. I was skeptical because I have never used Data Video before but I will consider buying more in the future

    Rated 5 out of 5 by from Great option if you need to bring in VGA I'm using this to bring in slide decks via VGA for conferences. It's flexible and the video quality is very good. Can output both SDI and HDMI and can capture SDI, HDMI, or VGA.

    Rated 5 out of 5 by from Great Converter Had to send presentation from a computer on stage to control room, VGA?, HDMI?, SDI?... no problem, this converter will work with any input to my SDI video switcher. It worked great with other brands like Black Magic, so don't have to worry about compatibility.

    Rated 5 out of 5 by from You will NOT be disappointed!! Seriously, obsessed with this thing. I needed to send VGA and HDMI outputs from laptops through a building SDI patch. Was a little nervous this was not going to be pushing enough power to send 720 signal through 300' of Coax cable. The DAC-70 happily surprised me, easy set-up, clear image and plenty of options. I will be purchasing another one tomorrow.

    Rated 4 out of 5 by from Works as advertised. I've only used this twice, once with VGA as the source and once with HDMI sending SDI to my switcher.� Worked great. I liked the HDMI loop thru still has the audio.� Setup was a little bit of a hassle.� I don't like that the software only runs on a PC.� We're a MAC shop, especially out on a shoot.� I have to drag along a PC laptop just in case I needed to make adjustments, etc.� If i could run the software on my macbook pro I'd give it a 5.

    Rated 5 out of 5 by from Ideal for live production switchers. If you are going SDI or HDMI into a live video production switcher, this is a fantastic converter to have on hand. Switchers can be finicky with resolutions and frame rates. This device can output exactly what your switchers needs. Presenters frequently still have 4:3 slides coming from a VGA source. This device can take the 4:3 VGA source and scale it to 1920x1080 SDI pillar boxed to maintain the aspect ratio. There are a variety of custom settings that can be configured via USB. The first 2 switches in the down position will recall the settings that were created on a computer. With the dip switches, you can can easily configure the inputs and outputs without the need for a monitor or difficult menu driven settings. For a great deal of use cases, this works out well. To get a VGA signal to maintain it's original aspect ratio though, you will need to plug the convert in via USB. I wish this was on of the default configurable settings on the device. The 2 aspect ratios configurable with the dip switches are full and span scan, which scales the picture horizontally but cuts off the top and bottom of the image. I suppose this would be useful if you were running 16:9 video fullscreen from a 4:3 source.
