Oji's Video Conference Countermeasures -New OS X Hacking! (263)

I'm 50 years old.Her life is 50 years and old songs, but she is alive.It is a new colonovirus evil that has deteriorated here and there and is becoming more difficult to match the buttocks every year.It is helpful not to go out on a painful day of the knee, but if you participate in a video conference, you can't ask you to listen to it.New roller evil ... Let's eat it in a pot!?

The reason why the video conference is unpleasant is that it is troublesome to adjust the appearance.Sometimes it is painful that your face is flirted with the display, but you have to shave your beard and prepare your beard even if you are at home.It's hard to see this in the background, and I want to do everything and do something.

So I thought.I don't need to process it like a recent Purikura, but I want to apply a soft focus, fly white with a light, or do a video processing that doesn't get out of my body.Of course in real time.If you don't have to use the wallpaper/virtual background, you want to do so.

So I thought."Filter".MacOS has a framework that filters still images/videos such as "Core Image" and "METAL" in real time, and the operation is light depending on the design, so the filter before entering the video into the video conference application from the FaceTime camera.If you handle it, you can reduce the trouble of growing.Even if you do not shave the beard for about a day, you will not notice the other side of the camera even if your skin condition is a little bad, if you can do it.

VLC

The first thing I tried was "VLC", a famous video player.The FaceTime camera has a function to output after filtering as a input device."File" → "Open Capture Device in the menu bar...Select "Capture" tab, select "Input Device", check "Video", select "FaceTime HD Camera (built -in)" and click "Open" to complete.This should display the video of the FaceTime camera on the screen (repeat if it is not displayed).

From this state, "Window" → "Video effect...If you select, a small window with a slider for image adjustment will appear.If you raise the "brightness" or "gamma" here, the video will jump white.The entire screen is faded, but you can't understand the sense of life in the house.This seems to be usable.

However, I noticed that VLC did not have the essential virtual camera output function.The processing itself is not heavy, but for some reason, there is a difficulty in stability, such as frequent phenomena that the image is solidified on the way.Unfortunately, there is no choice but to use other apps for video conferences.

Snap Camera

Snap Camera is an application that processes images of UVC cameras such as FaceTime cameras and output as virtual camera devices.It is a QT -based platform non -dependent app and also supports MacOS.

This Snap Camera does not have a function to fine -tune contrast or gamma values like VLC video effects, but has an effect that replaces the background and processes the face itself.Because it has a function to detect the contour of the face, it is given a make -up -like image processing to the eyes, the character images are overlapped, and a Purikura style (?) Image is obtained.It is an atmosphere that can not be used for business, but it can be used for "online drinking party" with a friendly friend.

However, Snap Camera cannot be used in the “ZOOM”, a video conference service/app that is becoming a standard.Although it can be used in Google Meet and Skype, the system load is quite high (depending on the selected effect), MacBook Pro 1.4GHz Quad Core Core i5 always consumes 40-60%CPU power.When we start a video conference, it is a level where the fever of the Mac itself and the sound of the fan rotate in less than 5 minutes are concerned, and it is true that regular use is honest.

Campwist

Camtwist, like Snap Camera, is an app that behaves as a virtual camera device with various effects, but is quite light.Unfortunately, it is not available in the latest version of Zoom (it does not support virtual camera devices), but Google Meet and Skype can be selected like FaceTime cameras.

The point is that multiple effects/filters can be stacked.After trying various things, if you adjust the brightness and contrast with "Brightness" and repeat the pencil -style effect called "ColorPencil", it will be the right finish to hide the independent beard.Although the end of development has already been announced, Catalina will work without any problems, so if ZOOM revives the support of virtual camera devices, it should be quite convenient.

The only virtual camera device app that can withstand practical use was the only "Camtwist" introduced last, but this genre should be quite needed.I am expecting a more advanced setting and a light operation app that will not be published at an affordable price.
