Blackmagic Design announced the new
These new versions add 3D LUT, time code and other functions, and support 1080p 24, 47.95p and 48p frame rates.
The new Blackmagic Micro Converter 3G model! The world's smallest broadcast quality converter, with 3G-SDI and new advanced features, including 3D LUT, time code, and supports 1080p24, 1080p47.95 and 1080p48 movie rates! Available now, prices start at $45.
The new Blackmagic Micro Converter 3G model is a small and compact broadcast video converter that allows you to connect and convert HDMI to SDI and vice versa.
Blackmagic Micro Converters can handle RGB or YUV 8-bit and 10-bit video formats, as well as all SD and HD formats with resolutions up to 1080p60. You will also get fully embedded audio and timecode support.
Blackmagic Micro Converters include a USB connection power supply and change settings through the Converter Utility on Mac and Windows. Since USB powers the converter, you can even power the converter from a TV or laptop. There are even LEDs for displaying power and video status. You can also purchase Blackmagic Micro Converter with AC power supply, which includes 4 adapters for international use.
This version includes a 17-point 3D LUT for color calibration of any monitor, projector or TV. You can also output a 3D LUT on the SDI loop output. It supports DCI format and movie rate, including 1080p24, 1080p47.95 and 1080p48.
This model provides you with two 3G-SDI outputs, which can be set to A-level or B-level format. It also supports video formats including 1080p24, 1080p47.95 and 1080p48.
Blackmagic claims that this is the smallest two-way broadcast quality converter in the world. It allows you to convert SDI to HDMI and simultaneously convert HDMI to SDI, both formats are different. It also supports camera control protocol conversion, so you can use BMPCC with SDI live production switcher.
You can use the free converter utility to change settings and update the converter software, which can be downloaded from the Blackmagic Design website. The software connects to the USB connection on the Micro Converter and can run on Mac and Windows computers. You can use the utility to change the name of the converter, which is useful for identifying which converter is used for which task. When using a two-way converter, you can even set the camera number, so the converter knows when it is controlled by the real-time production switcher. You can also choose between Class A and Class B of 3G-SDI video output.
The Micro Converter SDI to HDMI 3G model includes a 3D LUT for accurate color monitoring. This allows you to customize the appearance, color and gamma value changes in real time for on-site monitoring. The LUT can also be applied to 3G‑SDI loop output, allowing you to use the converter as a 3D LUT processor. You can also use a 3D LUT to obtain a color-calibrated graduated display through a low-cost computer monitor or TV. By using the DaVinci Resolve primary color corrector, you can create an appearance and then save it as a custom 3D LUT.
The new Micro Converter BiDirectional SDI / HDMI 3G model supports camera control, so you can use Blackmagic Pocket Cinema Camera with ATEM SDI switcher. The ATEM switcher sends camera control via SDI, and the converter can convert it to the camera's HDMI.
You connect SDI from the converter output to the switcher input, output the switcher program to the converter input, and then connect the HDMI converter input to the Pocket Cinema Camera. Then, you add the camera number in the Converter Utility, you can control the camera color corrector, prompt, and even record remotely. It can even work in reverse, and you can connect and control SDI cameras through an HDMI switcher (such as ATEM Mini).
The new Micro Converter 3G model supports HDMI and SDI timecode conversion. You can even fully support timecode in standard definition and high-definition video formats. If you have any HDMI device that supports time code, you can convert it to SDI and input the time code into a larger broadcasting system.
Blackmagic Micro Converter includes built-in SDI retime on 3G-SDI output. Before the converter sends the signal to other devices, SDI retiming will regenerate the SDI video, reduce SDI jitter and improve the SDI eye diagram. This can extend the cable length, because even the degraded SDI signal can still be used. Blackmagic Micro Converters also fully comply with SMPTE 259M, SMPTE 292M, SMPTE 296M, SMPTE 424M, SMPTE 425M Class A and B broadcast standards.
Blackmagic Micro Converter 3G models support SDI format, including:
HDMI video standards include:
Blackmagic Micro Converter 3G models are available now, prices are as follows:

If you owned Amiga in the age of 16-bit home computers, you might have chosen Amiga while gaming and some audio sampling due to its impressive video capabilities. In its heyday, Amiga produced broadcast-quality graphics that could even be seen in multiple TV shows in the late 1980s and early 1990s. It is fair to say that since the age of Guru Meditation, the television world has changed, and SD video signals will no longer be cut. With HDMI as the current connection standard, [c0pperdragon] can help you in the following ways here
Obtain the digital signal directly from the Denise chip of Amiga.
When I first thought about it, I might think of using FPGA, but the signal was brought to the expansion connector of Raspberry Pi Zero through the daughter board. Simply remove the DENISE display encoder chip, and then insert the long-pin processed DIP socket into the board to connect. Pi will start from
The project was originally created for BBC Micro with the goal of rendering a pixel-perfect representation of Amiga graphics on the HDMI output of the Pi. It should be noted that it can run on the original chipset Amigas, and only certain models with enhanced chipsets can run, so Amiga 600 owners seem at a loss. The required latency is very low, and it should have an advantage compared to some other solutions to the same problem.
, But it is not only suitable for large machines, it can also be used on more machines.
Well, FPGA is involved here. Caps with programmable Xilinx CPLDs can capture video signals and feed them into zeros, see
And vhdl source is here
In this particular case, the CPLD of the RGBtoHDMI project is not used. Only a few XORs and triggers are needed to prepare the signal to enter the Pi.
I really like the result.... :-P
Has anyone heard of the upgrade plan to support ECS and AGA plans?
It can work in ultra-high image quality, but cannot capture ECS video mode. The limitation is that the VGA frequency is 6 bits/pixel
I should know that I have written a lot of software, which is indeed the fact that Amiga is used for broadcasting.
There is a machine called QuesTech Cleo that can bend real-time pictures into various shapes in real time. Designing it involves some of the most extreme mathematical operations I have ever done. You can see its operation on almost all "pop charts" from 1990 to 2000.
I wrote a package called ShapeMaker to run on the Amiga, which allows the operator to drag the picture to any shape with the mouse, and then bind the shape's characteristics to the joystick axis. It can then be used to arrange effects sequences for live broadcast.
I did a laser maze project for the British TV show "K Factor", and every participant got an A500
Use genlock to reach the studio control room.
Amiga graphics can achieve perfect full-screen display and monitor shooting effects.
Do you have any literature or source code to see how it is done? I would love to see the mathematical principles of some of these machines/software
Thanks for the inside information.
When we get comments from people in the industry, this is the best Hackaday commentator who can provide us with professional opinions. Thanks for that!
Why is amiga not used by hackers? Why use gui etc. to use the whole system when possible?
Amiga OS is still with us, and there is an active community around it.
I am glad to see that this article uses my video on YouTube. But I think my spoken English is not good. For this, I apologize deeply. Yes, I am called Brostenen on YouTube, but to9xct is the name of my blog on BlogSpot.
Don't apologize for your English, as a person who can speak English, I am very flattered, and thank you for having learned my language, so I can understand you. (Although you may not just study English for me, I still appreciate it.)
Is this really pixel perfect? For me, the screen stretches vertically to 1080 pixels. What is the high-end ratio? 2×2, 3×3 or 4×4? Or does it depend on whether it is low resolution or high resolution, is it interlaced?
By adding optional buttons, you can enter the settings menu and make numerous adjustments.
However, if the amiga is running in low resolution mode, the standard setting is 4×4. For high-resolution mode (workbench), the pixels are scaled horizontally by 2 times. When in interlace mode, the vertical zoom is 2 times (fix it when blinking).
It is worth mentioning that RGBtoHDMI runs on raspee bare metal code without linux. You can use a 32MB SD card. Very clever design, probably the best 8-16 bit upconverter currently available. It already supports a large number of devices and supports all open source, so you can add support for new hardware and video modes.
Outstanding Work. More and more retro machines appear HDMI solutions, which makes me very happy ?
This is great! Does anyone know if there is something similar for the Atari 520 or 1040 STf model?
You can find all the information on the github page of the original project. :-)
I want mine! I want mine! I want my AGA!
So tell Sting!
You are very unlucky with this project. Due to PI limitations, this is technically impossible.
What are the limiting factors? Take a quick look. There should be enough GPIO. If you think there are various GPIO speed analysis, should there be enough space to support 28M pixel clock?
Waste of time... There are already many video signal converters
Yes, all ADCs that are running. Capture digital RGB to reconstruct the original signal 1:1
If you want to spend more than 7 times the price to buy a frame, please be my guest. I think you missed the point of this project. It was created to enable BBC Micro HDMI video output. It is possible to use modern monitors on these machines because the old monitors are too expensive and too expensive. Secondly, when creating this product, the cost will be greatly reduced, so everyone can have an upgrade program that does not flicker. Third, it is suitable for OCS Amiga, now it is suitable for OCS and ECS machines (minus a600), as well as the second version of the adapter. V2 has jumper options for OCS and ECS.
This means that using the standard/regular screen mode set in Workbench, Amiga500-Plus and possibly Amiga3000 can output HDMI. (When loaded for the first time after installation) All Amiga games work at a resolution that the adapter can reach.
I think this adapter is the best solution. If you need Amiga, do the following. (Or similar)
– Amiga500 / Amiga500-Plus.
-Only play games from the Golden Age of Amiga games (1988-1992).
– Use real floppy disks or Gotek drives.
-Or use the Tracker program to make music.
– And, if you really don’t use the highest screen mode.
If the list meets your needs for Amiga in the collection, then this adapter is what you need. Because you can use it with a 1080p or 4K TV, and a TV like this plus this adapter and the accompanying PI is usually cheaper in most cases than a frame monitor (then you still need a TV) or a real old CRT Monitor, you don't know when it will die or catch fire. Yes it is. If there is not enough space around you to provide good ventilation, an explosion may occur. In addition, you need to make sure that no dust will absorb moisture in the air, then short-circuit it and prepare the monitor for use in a recycling center.
Then say it again. If you want that kind of frame, spend 7 times more.
????
Is it possible to run filters and high-end output (such as the CRT style that comes with RetroPie)?
These are real game changers on the new TV.
If this is the case, this project has legs.
Can this be used in Amiga 1200 (standard high-resolution PAL mode) and 320×200 low-resolution mode? I bet it is easy to use the cap on the top of the Lisa chip to capture the RGB lines.
I understand that color mode/depth is the problem. But amiga 1200 does not support lower ECS/OCS depth; what if we force it to use these modes?
I would also like to know if there is such an RGBtoHDMI solution for the Amiga 1200-I went ahead and bought a RaspiZero and then realized that this mod is only available for 500/1000 models:(
Can it be done externally (through video output)?
Please be kind and respectful to help make the comment section great. (

The best mini projector is not only a gift from a traveling salesman. The mini projector is a handy gadget that allows you to enjoy some top entertainment no matter where you are.
Although they may not have a resolution to contend with
with
, The micro projector is very portable and can bring amazing visual impact. You can bring entertainment to the garden, watch your favorite shows under the stars, or provide a temporary game station for you and some friends. No matter where you are, family photos, family videos and the latest blockbusters can be easily shared.
So whatever you are looking for
From Prime Video, Netflix or
On family movie nights, looking for a 100-inch screen to solve the chaos of multiplayer games, or just interested in understanding what this technology can provide, we have summarized the best mini projectors below.
What we are looking for in the best mini projectors:
Lumen is a measure of the brightness of a light source. ViewSonic reports that a candle sits at around 14 lumens and the setting sun is around 400 lumens. It is 100,000 lumens on a bright sunny day.
A projector with ANSI lumens between 200-500 lumens will be very suitable for living rooms and smaller spaces with limited ambient light. Large rooms and brightly lit areas require more than 2,000 lumens of ANSI. This brightness is beyond the range of micro projectors.
The acronym "ANSI" standardized by the American National Standards Institute should follow any lumen measurement: for example, 1000 ANSI lumens.
Resolution refers to the number of pixels that the projector can display. The more, the more accurate the image will be. When providing full HD 1080p and 4K UHD devices, the pico projector is usually located between 420p and 720p, also known as HD support. When combined with enough lumens and deep enough contrast, these resolutions can still produce compelling image quality.
Contrast is a measure of the ratio between the lightest and darkest parts of an image. A contrast ratio of 15,000:1 means that the brightest white of the image is 15,000 times the darkest black. High contrast can make the image have higher details and fidelity, while low contrast can make the image look faded and lifeless.
For projectors, there is some interaction between contrast and lumen. A lower lumen projector designed for dim indoor spaces can provide lower contrast.
The available input connections determine how the projector receives input. The more interfaces available, the greater its versatility.
Micro projectors tend to prioritize the most common and therefore the most useful connection types, including HDMI, microSD and USB Type-A. Some models also include Bluetooth and WiFi connections, which can be used for screen mirroring on smartphones and tablets.
Audio interface is also very important, with 3.5 mm line output and Bluetooth function
Is connected.
The projection range refers to the distance between the projector and the screen. A projector has a certain distance range from which images can be projected, the closest distance can generate a smaller image, and a longer distance can generate a larger image. This is an important specification to consider when buying a projector, especially when using it in a small room.
Keystone correction (often called keystone correction) is a function that adjusts a deformed image to ensure that it appears square. A projected image that has not been corrected for keystone distortion may take longer to appear along one edge than the other edge. There are many reasons why the image may be distorted, including uneven projection surface or eccentric projector.
A projector with keystone adjustment will give you better control over the image. This is a standard feature of large projectors, but sometimes it is not found on micro projectors. However, its absence is not too strong. This just means that you need to pay more attention during the installation process.

The images produced by the Kodak Luma 350 are both large and detailed, making it an amazing mini projector. The 720p HD resolution is complemented by a contrast ratio of 3500:1, while 350 ANSI lumens helps keep the light bright (in darker environments).
Kodak provides many connection options to realize the versatility of playback. HDMI, USB and microSD interfaces are responsible for physical operations, while WiFi and Bluetooth allow wireless connection to iOS and Android devices. Luma 350 also has 4W built-in speakers.
Please note that the battery can only be used for two hours, so unless you can use a power bank, you can only use short videos.

Optoma ML750e is a micro projector that looks like a micro projector. Its proportions, vents and connection methods are all reminiscent of the brand's excellent full-size products.
The ML750e is a powerful device that can project 720p high-definition content to 3.2m to obtain an image size of 100 inches. This and the number of 700 ANSI lumens explain why the housing has such a large exhaust function. The colors appear bright and accurate, and provide weight and depth with a contrast ratio of 15,000:1.
The only disappointment here is that the onboard speaker has only one 1W and no built-in battery-the projector uses an AC power cord.
It will be connected to the device via HDMI, MHL or VGA (with the provided converter). It also has USB-Type A and microSD interfaces, and allows wireless connection with USB dongle. 3.5mm audio will allow you to take advantage of some better speakers. It has been around for a few years, so if you encounter any 3D content, then it can also be solved.

Viewsonic M1 Mini is an affordable mini projector suitable for indoor and outdoor home use. You can play photos and movies on the device via USB Type-A or HDMI connection, and then project them in Cinema SuperColour + to produce beautiful visual effects. Since there are no controls on the projector, a remote control is included, and the remote control is always required.
There are a variety of quality of life functions onboard, including automatic keystone correction and built-in brackets. The stand allows you to place the device above 360 degrees and protect the lens when not in use.
The integrated 2W JBL cube provides sound, although it is not cinematic, but you can hear the sound you need. The small size, light weight, and low price tag feels the most obvious in battery life, and can last up to 2.5 hours-but, for movies, this is long enough.

The size is 99mm long and 23mm thick Kodak Luma 150 can be easily slipped into the pocket of a jacket or backpack. The projector uses digital light processing (DLP) to introduce a large number of realistic colors to bring the media to life. Although small, there are many connection options, including wired and wireless connections. There is even a 1.5W mini speaker hidden here. All of this comes from its internal rechargeable battery. Although the resolution, two-hour battery life and brightness are modest at best, it is still a very beautiful gadget.
: Very portable
: Lack of lumens and batteries
Lumens: 60 ANSI
Contrast ratio 1,500:1
Maximum image size: 150 inches
Connection: HDMI, USB, microSD, AirPlay, Micracast, 3.5mm audio output

ViewSonic M1+ broke the "mini" boundary. However, for a slightly larger size and weight, a series of benefits can be obtained. The image quality is excellent, with accurate color representation and sufficient brightness. The 6W audio comes from two Harman Kardon speakers, and they sound pretty good for such a small device. The battery life is about 6 hours, so don’t worry, it will take you to entertainment all night long. Like Mini M1, the built-in bracket can work within 360 degrees and can double as a lens protector.
Viewsonic M1+ has a large number of connections, making it a multifunctional device. In addition to HDMI 1.4 and USB Type-A, M1+ also supports USB-C and MicroSD. WiFi and Bluetooth are also built-in, can be connected to a wireless smart phone, and also has 16GB of local storage.
: Multifunctional connection, internal memory, high-quality images
: Proximity is not "mini"
Lumens: 300 ANSI

Maximum image size: 100 inches
Connection: HDMI 1.4, USB Type-A, USB-C, microSD, WiFi, Bluetooth
Weight: 771g
Dimensions: 146 x 126 x 40 mm
The method adopted by Philips is slightly different from the typical palm-sized micro projector design of the PicoPix Nano PPX120. It is almost a cube with a length of 62mm along the longest side and a weight of only 136g. Its shape means that the projection is both beautiful and stable, and can avoid the lack of keystone correction.
It can project a moderate 60-inch image at a distance of 3.5m, with surprisingly good color performance and resolution, although its upper limit is only 360p, and it does require manual focus. The built-in 2W speaker provides audio, with a 3.5mm jack, which can be used with headphones or external speakers. The battery life is up to 80 minutes.
The physical input is connected via a micro USB port. It will also mirror the smartphone screen via WiFi-a clever trick for such a small device.
: Great for sharing pictures and movie clips
Short battery life and limited connections
