The Best Mini Video Converters HDMI to SDI / SDI to HDMI

By | July 15, 2015

Format conversion is an essential part of working with video equipment. Two of the most common formats are HDMI and SDI, which allow footage to be converted from consumer-grade gear to professional video equipment and vice versa. Some of the best mini video converters come from Atomos and Blackmagic Design, two leaders in the world of video equipment.

The Atomos Connect H2S, Atomos Connect S2H, Atomos Connect AC H2S and Atomos Connect AC S2H are the world’s smallest battery powered and AC powered HDMI / SDI mini video converters on the market. The Blackmagic HDMI to SDI and Blackmagic SDI to HDMI mini video converters provide powerful performance in professional video applications and environments. Let’s take a look!

As mentioned above, the Atomos mini video converters are the smallest in the world! They fit in your pocket and make format conversion a breeze. The H2S versions convert HDMI input to two SDI outputs, while the S2H versions convert SDI input to one HDMI output and one SDI loop output. Each mini video converter features 3:2 and 2:2 pulldown, which allows you to extract 24P/30P from 60i and 25P from 50i/pSF equivalents in real time. The built-in flashlight mode uses an LED torch so you can work in dark or dimly lit applications. A test pattern generator and audio test tone are also available.

There are two sets of Atomos mini video converters: Connect and Connect AC. Connect AC models draw power from standard AC cables, but the Connect models are something special. They utilize a patent-pending continuous power battery system. Power can be drawn from either an internal battery or external battery (included). The internal battery gives you up to an hour of operation in normal conversion mode, while the external battery gives you up to 10 hours of operation! The external battery automatically charges the internal battery when connected to the device. Connect models include an external battery, 9V AC adapter, AC battery charger and a 12V DC travel adapter.

The continuous power dual battery system allows the Atomos Connect mini video converters to be truly portable. You can take one with you out in the field, whether that’s travelling to the next town or backpacking up a mountain! The included battery charger can charge up to three units at once, so you’ll always have what you need.

Blackmagic Mini Video Converters HDMI to SDI / SDI to HDMI

Blackmagic mini video converters are great for converting HDMI to SDI / SDI to HDMI between consumer-grade devices and professional video equipment. Although they aren’t as compact and portable as the Atomos converters, these devices still operate at a professional level of power and reliability. HDMI to SD, HD, 3G or 6G-SDI and vice versa provides resolutions up to Ultra HD 4K (3840 x 2160) and DCI 4K (4096 x 2160). Input video format is automatically detected and switches to the corresponding output format. Standard connections allow Blackmagic mini video converters to easily work with existing workflow setups. Audio sampling works at 24-bit, 48kHz. HD scaler and SD down conversion technology compliments 4:2:2 sampling and color precision. You can control settings through either the built-in DIP switches or with a USB connection to a Mac or Windows computer. These devices draw power from 12V universal power supplies. Both versions meet SMPTE 292M, SMPTE 259M, SMPTE 296M, ITU-R BT.656 and TU-R BT.601 standards.
