Capturing Video

Attention

This page is not maintained anymore and contains information referring to features or functions from earlier versions of Kdenlive that are deprecated or have been superseded by something else.

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 Kdenlive.

To perform a capture:

  • Plug in your device to the firewire card and turn it on to play mode

  • Click the Connect Button

  • Click the Record Button – note it toggles to grey while you are recording

  • 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. *[RGB]: Red, Green, Blue *[VFX]: Visual Effects *[feathering]: Smoothing or blurring the edges of a feature *[LFO]: Low-Frequency Oscillation *[dB]: decibel *[LUFS]: Loudness Units Full Scale *[AI]: Artificial Intelligence *[LLM]: Large Language Model *[HSV]: Hue, Saturation, Value *[SOP/Sat]: S(lope), O(ffset), P(ower) / SATuration *[CDL]: Color Decision List *[HSL]: Hue, Saturation, Lightness - Using HSL color space is useful for subtle color changes *[px]: pixel *[hh:mm:ss:ff]: hours:minutes:seconds:frames *[Hz]: Hertz *[CIE]: Commission internationale de l'éclairage, French for International Commission on Illumination *[DCI]: Digital Cinema Initiative *[nadir]: direction pointing directly below a particular location *[OS]: Operating System *[decibel]: Unit of measurement (dB) for sound levels *[clipping]: A form of distortion that limits a signal once it exceeds a threshold *[Spectrogram]: Visual representation of the spectrum of frequencies of a signal as it varies with time *[prevent clipping]: Dynamic range compression (DRC)is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range. *[SNR]: Signal-to-Noise Ratio *[dbFS]: Decibels relative to full scale
