Black magic bear camera

I don't know which one will kill me!

Delay interval can turn on the interval shooting function to automatically record still frame images at the following intervals:?

Framework: 2- 10?

Seconds:1-10,20,30,40,50?

Minutes: 1- 10

For example, you can set the camera to record a still frame every 10 frame for 30 seconds and 5 minutes. Video playback can present high-speed playback effect. When you want to record at normal speed, please note that this function can be turned off when it is set to "Off".

1: EF bayonet model

2: 10 inch display

3: Connect the external power supply and battery power supply at the same time, and the camera only uses the external power supply. When the external power supply is disconnected when the battery is connected, the camera will switch directly to the battery power supply without interruption.

4: When turning on the machine, press the power button. Just press the button when you turn it off.

5: The recording card is CFast 2.0, which can record 4K, HD or ultra-HD videos.

6. The frame rates of the subject are 3.98, 24, 25, 29.97, 30, 50, 59.94 and 60fps respectively.

7: When recording, if the sensor frame rate and the project frame rate are different, the playback speed of the clip will be different. For example, the project frame rate is set to 24 frames per second, which is the same as the post-production timeline. If the sensor frame rate is set to 80 frames per second, the clip will be played back on the camera and post-production timeline in slow motion mode.

8: Press the "SLATE" button to open the slate function on the touch screen. Press SLATE again to turn off the function. Slate function can be used to input metadata of material and set camera ID.

9. In "Dual Card Mode", the machine can use two card slots to record high frame rate images in CinemaDNG RAW format, and record one frame alternately on each card. This alternate recording mode can halve the workload of each recording card slot and realize the amazing speed of ultra-high data rate!

10: CH SOLO mono and mute buttons, which can monitor 1 channel and 2-channel stereo channel respectively through headphones. For example, to monitor only Ch 1 audio, press the CH 1 SOLO button or the CH 2 MUTE button. Press the above button again to monitor both channels.

1 1: The 12G-SDI output interface of this machine can output high-definition and ultra-high-definition videos.

12: synchronous input: connected to "REF"

After BNC interface, Blackmagic URSA can synchronize to common synchronization signals such as black field or three levels. In this way, when multiple cameras are connected to the switchyard, you can ensure that Blackmagic URSA is synchronized with other SDI video devices.

13: Press the "DISP" button on the camera control panel to switch between the recording screen and the playback screen. (to be verified)

14: The best ISO for Dark Bear is ISO 400.

65438+ 15: Microphone level can adjust the recording level of the built-in microphone.

16: phantom power supply Select "ON" to turn on phantom power supply, and select "OFF" to turn off phantom power supply. Only when the audio input option selects input and the input level is set to microphone low or microphone high can the phantom power setting be turned on.

17: Drag the speaker volume icon to the left or right to adjust the audio monitoring level. When the headset is connected, the headset settings will be displayed in the interface. If no headphone connection is detected, the speaker settings will be displayed. When recording or playing a clip, the headphones are turned on. The built-in speaker is turned on only when playing.

18: codec settings allow you to play RAW, RAW 3: 1, ProRes

444 XQ and more cinema students and apples.

ProRes codec is available.

19: There is a dynamic range of 12 in movie mode. When recording in CinemaDNG RAW format, you can only use the dynamic range setting of film movies.

Use REC709 color standard to shoot high-definition video in 20: Video mode. Record the compressed video format supported by the camera.

2 1: Within the sensor frame

Select the Match option in Rate so that the sensor frame rate is consistent with the project frame rate setting.

22: SDI mode enables 12G-SDI output to switch between ultra HD and HD video. When the recording resolution is set to HD, only HD content is output.

23: Primary SDI

The override (primary SDI override) setting allows you to select which override information is displayed through the rear 12G-SDI output interface.

24: Former SDI

Overlay Settings (SDI Overlay) allows you to select which overlay information is displayed through the HD-SDI monitoring output interface.

SDI output of rear panel is 2 160p23.98, 24, 25, 29.97, 30, 50, 59.94, 60. 1080p23.98、24、25、29.97、30、50、59.94、60 .

3G-SDI monitoring output 1080p23.98, 24, 25, 29.97, 30, 50, 59.94, 60.

25: Guideopacity Sets the opacity of the frame reference line.

26: HDTV displays the safe action area and caption images with the aspect ratio of 1.78: 1, which is suitable for 16:9 HDTV and computer screens.

27: Lost Frame

28: 12V DC output interface is suitable for Blackmagic URSA viewfinder or Blackmagic URSA.

Driven by the studio viewfinder. When the interface is connected with other accessories, ensure that the power consumption is lower than 18W.

Shutter angle Shutter angle defines the degree of dynamic blur in video and can compensate for different lighting conditions. In most cases, a shutter angle of 180 degrees can produce a satisfactory dynamic blur effect. For example, when the shutter is fully opened at 360 degrees, the photoreceptor can receive the most light. This is suitable for low light conditions where there is only slight motion in the picture. However, if shooting a fast-moving moving moving scene, a narrow shutter angle can minimize dynamic blur and get a clearer and clearer image.

? When shooting at 24p in countries with 50 Hz power supply specifications, adjusting the shutter angle to 172.8 degrees can minimize the flicker of 50 Hz light source.

Conversion formula of shutter angle and shutter speed

Shutter angle/frame rate * 360 = shutter speed

Conclusion: The larger the shutter angle, the longer the shutter time under the premise of constant frame rate.

Audio: XLR audio input interface is a balanced XLR input interface, which can connect external analog audio of professional equipment, such as mixer, PA system or external microphone. The XLR interface can provide phantom power, so a non-self-powered microphone can be used. To enable the phantom power supply, select the Input option in the Audio Input setting of the touch screen menu, and select the Microphone Low or Microphone High option in the Input Level setting. Scroll through the menu, find the Phantom Power Settings, and then select Open. Select Off to disable the phantom power supply. When the Audio Input setting is selected as the Input option and the Input Level setting is selected as the Microphone Low or Microphone High option, the phantom power is turned on.
