Blackmagic Design today announced Beijing based music production training school UpChord Music has been streaming its courses to students around the world using ATEM迷你 Pro and ATEM迷你 switchers.
“We didn’t offer online classes until we were asked by Shanghai Theatre Academy in 2019 to teach their students music performance, because we didn’t want to spend too much time frequently traveling between Shanghai and Beijing,王志成说, UpChord Music的创始人.
当把课程搬到网上时, UpChord’s biggest concern was how to ensure the quality of online classes would be as close to that of offline classes as possible. “在线课程不是简单的在线视频聊天. 作为专业的音乐培训机构, we need to show our students 1080p HD with high quality stereo sound and low latency interaction, 只有智能手机或网络摄像头是不可能实现的.”
在中国传媒大学校友的帮助下, where most of the graduates are professionals in the film and broadcast industries, Wang built up an online teaching system by combining his JoyChord system with a video switcher.
“The first video switcher we used cost more than USD $15k and supported up to 1080i60. But we found that interlaced video didn’t meet our demand because the lines in musical notation look shaky in interlaced format. We worked out a solution to this issue but soon we found it made musical notation look nasty. Therefore, we started looking for a better switcher capable of 1080p HD.”
“We also wanted it to be as compact as possible because we wanted to put it in a flypack so we would be able to take it anywhere when doing presentations at different colleges and schools. 我们选择了Blackmagic Design的ATEM tv Studio HD, 它支持1080p，而且非常紧凑, 连同HyperDeck Studio Mini, 只占用了一个机架单元.”
“当ATEM迷你发布时, it went beyond what I knew about how compact a professional switcher could be. Also, what impressed me most was its ability to convert and sync sources automatically, 哪个对初学者非常友好. They just need to connect the cables and the ATEM迷你 will take care of all the rest. 此外，它的音频混音器功能强大. 所以，我们毫不犹豫地买下了它.”
The new ATEM迷你 Pro caught his attention again when launched this April, 哪些带有硬件流媒体等新功能, h.264录音和多视图. “我们也将其融入到我们的工作流程中. The way of operating is identical to that of operating the original ATEM迷你. When I gave it to our teachers who had been streaming with the ATEM迷你, 他们很快就熟悉了这种新型号.”
“Both of the models allow us to save presets including the streaming and picture in picture setups, 简化工作流程.”
对于一个典型的UpChord在线课程, 使用三种馈源, 包括DAW的用户界面, the JoyChord interface made up of a virtual keyboard and real time generated music notation and a live camera feed that captures the keyboard the teacher is playing going into a video processor, 然后把这三段视频缝合在一起. The stitched video and a live feed of the teacher on a green screen are then sent to the ATEM迷你 Pro, where the teacher’s video is imposed on the stitched image using the switcher’s chroma keyer, 而通道徽标则覆盖了下游键控器.
Stereo audio is embedded into the HDMI feeds and the teacher’s voice is picked up by a mic as mono sound and goes into the ATEM迷你 Pro via the Mic input.
程序通过USB-c进入正在运行ZOOM的计算机, 可以播放立体声和高清视频吗, 以及实时交互.
“有了这个用ATEM迷你 Pro构建的在线教学解决方案, when the coronavirus outbreak forced most of training facilities to halt their classes, 我们能够立即将我们的课程完全转移到网上. 直播也帮助我们打破了地域障碍, allowing more excellent teachers around the world to join us via the Internet and bring our students more diversified high quality content!王总结道。.
