동영상 캡처하기

Note

인력 부족으로 KDE 5로 포팅하는 과정에서 최소한 Firewire와 웹캠 캡처는 제거되었습니다.

Kdenlive는 Firewire, FFmpeg, Screen Grab 및 Blackmagic과 같은 외부 장치에서 동영상을 캡처하는 기능을 제공합니다.

You configure video capturing from Settings -> Configure Kdenlive -> Capture (more on this here).

You define the destination location for your captures by using Settings -> Configure Kdenlive -> Environment -> Default Folders (more on this here).

To execute a video capture, select the Record Monitor and choose the capture device from the dropdown in the bottom right.

Firewire

This option is not available in recent versions of Kdenlive. Use dvgrab directly in a terminal to capture video from firewire.

This captures video from sources connected via a firewire (also known as - IEEE 1394 High Speed Serial Bus) card and cable. This functionality uses the dvgrab program and the settings for this can be customized by clicking the spanner icon or choosing Settings>Configure Kdenlive. See Configure Firewire Capture.

캡처를 수행하려면:

장치를 Firewire 카드에 연결하고 재생 모드로 켭니다

연결 버튼을 클릭

녹음 버튼 —을 클릭하면 녹음하는 동안 회색으로 전환됩니다

Click the Record button again to stop capture. Or click the stop button.

Once capturing is finished, click the disconnect button

In the Captured Files dialog, click the import button to have the captured files automatically imported into the project bin.

Note

If your device does not start playing the source device when you click the record button, you may have to start playback on your device manually and then click record.

FFmpeg

I believe this captures video from an installed Web Cam using Video4Linux2.

화면 녹화

This captures video of the PC screen. In version 0.9.2 it uses recordMyDesktop to do the capture. There is an open defect with this functionality in ver 0.9.2 — See bug tracker ID 2643.

In version 0.9.3, the screen grab is done by the ffmpeg functionality instead. For screen capture to work in ver 0.9.3, the version of ffmpeg installed needs to have been compiled with the --enable-x11grab option. Ubuntu comes with an ffmpeg version compiled with this option.

To check on your linux distro, type ffmpeg -version in a terminal and look for --enable-x11grab in the reported configuration info. ^[1]

If you are capturing the screen and using the X246 with audio settings and you get a crash as shown in the screen shot ...

... then consider creating a profile for audio capture where -acodec pcm_s16le is replaced by -acodec libvorbis -b 320k. See Configure Kdenlive.

Blackmagic

This is for capturing from Blackmagics decklink video capture cards (AFAIK). Not sure how stable this code is at the moment. See defect 2130.

Footnotes

↑ There are now two branches of ffmpeg: a Libav branch and an ffmpeg.org branch. The ffmpeg version from the latter branch reports the configuration when you run with ffmpeg -version. The Libav version does not. So this method to check for the --enable-x11grab does not work if you have the Libav version of ffmpeg.
