The first three are quality-wise the same (exactly the same DV 25Mb/s standard definition codec), just packed differently into the file. The settings applied here to define how dvgrab will be used to capture the video. The firewire capture functionality uses the dvgrab program. 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 video player is used by the DVD wizard previewer.Īt least Firewire capture was removed in porting to KDE 5 due to lack of manpower.Ĭonfigure the capture devices (Firewire, FFmpeg, Screen Grab, Blackmagic) from this section. Images and audio files are edited by the external applications defined here. Note there is no application for video editing - because Kdenlive is a video editor. This setting controls what application opens when you choose edit clip for a clip in the project tree. 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. This setting controls where Kdenlive expects project files to be by default. And yes that is a minus 4 in the example - as per the mlt doco - numbers <0 implement threading without dropping frames. If you want to experiment with multi threading in versions higher than 0.9.10 you could add something like 'real_time=-4' to a custom render profile. Using this has potential side effects - see this forum post from the author of the Melt program. This parameter increases the number of threads the program uses for video decoding and processing (but not encoding which is controlled via Render>Encoder threads). This number was passed to melts real_time consumer property. Processing threads: This is experimental and was removed in ver 0.9.10. ( Multi-threading is supported for MPEG-2, MPEG-4, H.264, and VP8)

Increasing this parameter may not have an effect if you have changed the proxy encoding settings using Project Settings to a codec that ffmpeg does not do multi-thread on. This will be what kdenlive passes to the ffmpeg -threads parameter. Proxy Clips - Concurrent Threads This will set the number of threads the program will attempt to use when calling ffmpeg to encode proxy clips. 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. Only advanced users would really need to change these settings. This setting tells Kdenlive where to find the MLT executables and profile files. Track Height - defines the default track height in pixels for the tracks on the timeline. If unchecked you will get a single waveform as the audio thumbnail.ĭisplay clip markers comments - Turns on Show Marker Comments by default.Īutomatically split audio and video - tracks will automatically have the video and audio portions split into a video and audio track when they are dragged from the project tree to the timeline i.e., this setting will cause Kdenlive to automatically do what the Split Audio function on the Clip Menu does. Thumbnails - Audio - Turns on Show Audio Thumbnails by default.Ĭhannels (ver 0.9.10) - if checked you will get a separate waveform in the audio thumbnail for each audio channel in the audio track. Thumbnails - video - Turns on Show Video Thumbnails by default.
