The simplest way to achieve mobile games, host broadcast - AVerMedia GC570 capture card out of the box evaluation
â–² In recent years, the domestic anchor industry has continued to rise, and more and more people are participating in the anchor army. Some people may rely on anchors to make a living, and some may just play and play, like entertainment anchors and PC games. The anchor is fine. Only one OSB+camera+high PC is required. Like mobile phones and XOX game anchors, how to obtain high-quality video signals and broadcast live in real time is something that many newcomers do not understand. In fact, only need to add a capture card will be able to solve.
▲ I am also a mobile phone game friend and asked me this question: “Using the camera to shoot the mobile phone screen, the effect is very bad, how to do?†Only then helped him online again, scouring a piece of AVerMedia acquisition card GC570.
â–² When he first asked me, my first reaction was the acquisition card of BMD. Then I thought about the price and thought about the difficulty of professional capture card operation. Still, I still wanted to find a dedicated capture card. A little fly. After the purchase, I share with you by the way.
Specifically why would you choose this capture card, let me slowly and everyone say.
â–² Demonstrate the use of 5D3 as an external device. In the testing process, you use the input source of 3 cameras + BMD switcher.
The summary is still on the front to allow people who have no patience to read it.
advantage:
1. The included software RECentral is simple, practical, and full-featured when used by a single person.
People who have no video processing and live broadcasting experience are very friendly. They can be said to be fools, and they were the main reason I chose at that time.
2.1080P60 is sufficient to fully broadcast and record most of the competitive games.
3. Support X-BOX, Android, Apple and other devices live, compatible with strong.
4.Win10 driver-free (other systems not tested)
5. Recording format is MJPEG
MJPEG format Compared to H.264, the algorithm has a low CPU occupancy rate, which means short press time and low delay. At the same time, it is frame-by-frame compression single-frame pictures, and the image quality is high, which facilitates later editing.
Disadvantages:
1. The price is high.
2. Compared with H.264, the MJPEG format is very unfriendly to hard disks, occupies a large storage space, and requires fast tapes.
3. The use of three-party software such as OBS, you need to select the RECentral plug-in to capture the video correctly, directly capture the capture card resolution error.
4. The live sound and picture are not synchronized, there is a delay, and communicate with the technicians. The official parameter is 70MS. Using RECentral complies with official parameters, and the delay with OBS is approximately 0.4s.
â–¼ convention, a picture flow
Pull out the carton pack, the outer black, the inner blue, with hollow decoration.
â–¼On the back is product information, accessories, a bunch of language product features and a Chinese sticker
â–¼ The interior is protected with a sponge and the capture card is wrapped with an anti-static protection bag
â–¼ Capture card body
â–¼Accessories include manual, installation manual, 3.5mm audio cable and HDMI cable
â–¼ capture card even with lights ... ... from the earliest 1394 capture card to the present, used no less than twenty or thirty capture card, the first see with a light, but also in line with the hearts of the comrades anchor.
â–² The installation process is relatively simple and it is skipped.
To mention one thing is that the mobile phone needs a micro hdmi to HDMI switch or IPHONE to HDMI transfer box.
â–¼ Give everyone a wiring diagram to facilitate the novice wiring.
â–¼ The main interface is generally like this. All major functions have been marked for everyone
▼ Do not say if the video has not been selected. The audio selection means “Digital Audio Interface†represents the audio source carried by HDMI. “Line†refers to the music carried by 3.5mm.
â–¼ In the recording window, we can customize the quality of the recorded video as needed. At the same time, the middle part of the lower part has the time that the currently selected hard disk can record.
,
▼It is worth mentioning that the software even comes with a “timely editing mode.†If you don’t understand it, I’ll simply say a feature. Live playback in real time. When we watch the game, every time there’s a wonderful shot, there will be a return shot to let everyone To appreciate it again is this feature.
â–¼ Live platform selection. The default is to bring some large-scale live broadcast websites abroad. However, these websites cannot be accessed domestically. Therefore, RTMP protocol is still required for live broadcasting. Just fill in the RTMP address and key.
â–¼ The live screen can be superimposed with windows. The types of overlays include pictures, videos, web pages, and text.
â–¼ You can set all the overlay windows and the setup process is very simple.
â–¼ also comes with a file manager, you can manage the recorded video and share, but sharing support for Facebook and youtube, or the same ... the country can not see.
â–¼ To set the interface is to make some global settings for the software, I feel the most practical is the shortcut keys.
â–²The specific use steps introduce a little less, because the person who needs specific operations is bought, the person who bought has instructions, and the description is certainly more detailed than I write, mainly to introduce the main functions and share with me Practical experience.
â–² Choose this piece of acquisition card actually more or value the software that comes with it, the software itself is more comprehensive, and the burden on the CPU is even smaller.
â–² His software itself is basically the same as OBS. Because I wanted to see the actual performance of this capture card and its own software, I3 used a low-end I3 computer with its own software +GC570. The overall CPU usage is stable at around 85%, while using OBS+GC570 is around 95%, so it is recommended that students who are interested in this option choose their own software.
â–² At the same time, in contrast to OBS Studio, lack of studio mode, studio mode can achieve better lens, superimposed window switching, but it needs other people to assist, and the general anchor may be more of a person. Live broadcast. So how to choose to see their own needs.
â–² And for the capture card itself, I tested the XBOX, mobile phone, camera EX280, SLR 5D3 and PC with no problems, compatibility and stability are good.
The problem of unsynchronized sound and picture hopes that the official can optimize it in time.
Finally, I attached a video recording of a small live event I made with AVeranga GC570. All the staff except the host and the guest were only me... How can it be a tragic word to describe...
The stepping motor is an induction motor. Its working principle is to use electronic circuit to supply power when the DC power is changed into components. The multi-phase timing control current is used to supply the stepping motor with this current, and the stepping motor can work normally. The driver is the time-division power supply for the stepper motor, multi-phase timing controller.
