Stop device on loss of focus

Stops the selected capture device when focus is switched away from the capture application.

Show video when device is stopped

Displays the current frame when the selected capture device is stopped.

Show video when device is fast-forwarding and rewinding

Displays video in the capture preview window when you fast-forward or rewind the device.

Add new clips to project media

Select this check box if you want to add captured clips to the Project Media window when capturing is complete.

Simulate device pixel aspect ratio

Displays square pixels in the capture preview window even if the capture format is using nonsquare pixels.

Fail on dropped frames

Select this check box if you want to stop capturing if a dropped frame is detected.

When capture fails, stop batch capture

Select this check box if you want to stop an SDI batch capture if a dropped frame is detected.

Enable HDV scene detection

Select this check box if you want to create multiple files if scene changes are detected. When the check box is cleared, HDV clips will be captured to a single file.

Preroll

Type a value in the box to specify the number of seconds of preroll Video Capture should use for SDI batch capture.

When you click Capture Clips , on the Clip Log tab, Video Capture will seek to a point prior to your Timecode In setting determined by the number of seconds you enter in the Preroll box. Video Capture will begin playback at the preroll location, and switch to capture when it reaches the timecode you specified in the Timecode In box.

Notes:

• Batch capture will fail if there is not enough lead-in time. The deck must be able to find the timecode that equals the Timecode In value minus the Preroll value.

• VITC and HANC timecode sources require less preroll than RS-422, as RS-422 needs time to synchronize timecodes with video frames.

Maximum RAM buffer size

Drag the slider to allocate a portion of your system memory as a buffer. During capture, this buffer is used to prevent dropped frames if your hard disk is unable to write a frame.

When performing compressed capture to MXF format, increasing the buffer size can help prevent dropped frames when encoding complex frames.

MPEG video quality

When capturing to compressed formats, you can drag the slider to adjust performance. When you drag the slider to the left, you can increase performance by decreasing video quality. When you drag the slider to the right, higher-quality video is captured, and more processing power is required.

Quality settings affect various types of material differently. With some experimentation, you may find that certain types of scenes can be captured at lower quality settings with little or no apparent loss of quality. Other material may need the highest possible setting to achieve the desired quality level.

Device type

Choose IEEE 1394/MPEG2-TS Device.

Device

Choose your HDV camera.

Video

Choose a setting from the drop-down list to specify the desired video format.

Details

Displays information regarding the capture device specified in the Device drop-down list.

Device type

Choose AJA Video Device.

Device

Choose your device.

Input

Choose SDI or HDMI. If HDMI is selected, only two channels of audio will be captured.

Video format

Choose a setting from the drop-down list to select the format that matches the signal connected to your SDI card.

Audio format

Choose a setting from the drop-down list to specify the desired number of channels for capturing SDI-embedded audio.

Multichannel audio capture is available only if supported by your camera or deck.

Timecode Offset

If video capture is not frame accurate, type a value in the box or use the spin control to adjust timecode.

Use progressive segmented frame (psf) video formats

Select this check box if you want to capture from a device that stores and transfers progressive-scan frames by dividing fields.

Use 10-bit encoding

Select this check box if you want to capture 10-bit source material for increased color resolution. Source material with gradients in the background can benefit from 10-bit encoding.

When you use 10-bit video in your project, choose 32-bit floating point (video levels) from the Pixel format setting on the Video tab of the Project Properties tab.  

Do not select this check box if you want to capture with MXF encoding.

Device type

Choose Blackmagic Design DeckLink.

Device

Choose your device.

Video

Choose a setting from the drop-down list to specify the desired video format.

Audio

Choose a setting from the drop-down list to specify the desired number of channels for capturing SDI-embedded audio.

Multichannel audio capture is available only if supported by your camera or deck.

Use 10-bit encoding

Select this check box if you want to capture 10-bit source material for increased color resolution. Source material with gradients in the background can benefit from 10-bit encoding.

When you use 10-bit video in your project, choose 32-bit floating point (video levels) from the Pixel format setting on the Video tab of the Project Properties tab.  

Do not select this check box if you want to capture with MXF encoding.

Timecode source

Choose a setting from the drop-down list to specify the desired timecode source.

Timecode offset

If video capture is not frame accurate, type a value in the box or use the spin control to adjust timecode.

Applies only to RS-422 timecode sources.
