This feature can be useful for placing the play head at the correct spot in clip relative to an important bit of audio.

    Environment

    MLT Environment

    This setting tells Kdenlive where to find the MLT executables and profile files. Only advanced users would really need to changing these settings. Kdenlive is basically a front end to the MLT program and this setting tells Kdenlive where to find the engine that runs the whole application.

    Default Folders

    This setting controls where Kdenlive expects project files to be by default. It also controls what folder Kdenlive will use as a temporary file storage location and it controls where files captured from an external source will be saved.

    Default Apps

    This setting controls what application opens when you choose edit clip for a clip in the project tree. Note there is no application for video editing - because Kdenlive is a video editor. Images and audio files are edited by the external applications defined here. The video player is used by the DVD wizard previewer.

    Capture

    Configure the capture devices (Firewire, FFmpeg, Screen Grab, Blackmagic) from this section.

    Configure Firewire Capture

    The image shows the Configure Firewire capture tab which can be accessed from the Settings -> Configure Kdenlive menu or from the spanner icon in the Record Monitor -> Firewire

    The firewire capture functionality uses the dvgrab program. The settings applied here define how dvgrab will be used to capture the video.

    Capture Format options are

    • DV RAW
    • DV AVI Type 1
    • DV AVI Type 2
    • HDV

    The first three are quality wise the same (exactly the same DV 25Mb/s standard definition codec), just packed differently into the file. Type 2 seems to be the most widely supported by other applications.

    The raw format contains just the plain video frames (with audio interleaved) without any additional information . Raw is useful for some Linux software. Files in this format can also be played with Windows QuickTime when renamed to file.dv .

    AVI files may contain multiple streams. Typically, they include one video and one audio stream. The native DV stream format already includes the audio interleaved into its video stream. A type 1 DV AVI file only includes one DV video stream where the audio must be extracted from the DV video stream. A type 2 DV AVI file includes a separate audio stream in addition to the audio data already interleaved in the DV video stream. Therefore, the type 2 DV AVI file is redundant and consumes more space.

    HDV is a high-definition format used on tape-based HD camcorders.

    Add recording time to captured file name option: If this is unchecked then each captured file will get a sequential number post-pended to the file names listed in the Capture file name setting. With this checked, a date and timestamp (derived from when the footage was captured) is post-pended to the capture file name. eg capture2012.07.15_11-38-37.dv

    Automatically start a new file on scene cut option: With this checked it tries to detect whenever a new recording starts, and store it into a separate file. This is the -autosplit parameter in dvgrab and it works by detecting timecode discontinuities from the source footage. Where a timecode discontinuity is anything backwards or greater than one second it will start a new capture file.

    The dvgrab additional parameters edit box allows you to add extra dvgrab switches to the capture process that will run. See dvgrab manual for more info.

    Configure Screen Grab Capture

    This shows the configure tab for screen grab in ver 0.9.3 of Kdenlive. It will be different in ver. 0.9.2 because that version used Record My Desktop to do the screen capture.

    Jog Shuttle

    Configure a connected Jog-Shuttle device. Contour ShuttlePro and Contour ShuttleXpress are known to work.

    Ensure that your Jog-Shuttle device is connected and working. An udev rule may needs to be defined to set the appropriate rights to the Jog Shuttle device file. If Kdenlive does not recognize the device file at startup, enter the device-path to the text field: "/dev/input/event4" (to be determined by "cat /proc/bus/input/devices").

    Enable Jog-Shuttle. For the Contour ShuttleXpress the buttons 5 - 9 are relevant, whereas Contour ShuttlePro uses all buttons. The actions for the jog- and the shuttle wheel are working as expected.

    Playback

    Configure the Video and Audio drivers and devices. For advanced users only.

    In version 0.9.4 of Kdenlive, checking the "use Open GL for video playback" checkbox turns on the ability to have audio scrubbing available for use in the clips. Audio scrubbing lets you hear the audio at the playhead position as you drag the playhead so you can quickly find a particular sound or event in the audio. This feature can be useful for placing the play head at the correct spot in clip relative to an important bit of audio.

    Transcode

    This controls the transcode functionality. The parameters section are ffmpeg parameters. Find help on them by issuing ffmpeg -h at a command line.

    Transcode Options

    Option Description Parameters Meanings of Parameters
    Wav 48000Hz Extract audio as WAV file -vn -ar 48000 -vn=disable video, -ar 48000 = set audio sampling rate to 48kHz
    Remux with MKV - -vcodec copy -acodec copy -sn copy the video and the audio. -sn = disable subtitles
    Remux MPEG-2 PS/VOB Fix audio sync in MPEG-2 vob files -vcodec copy -acodec copy copy the video and the audio
