Capture session

To record video to disk, you must set up a capture session. It determines where the recorded video files are stored on disk and how they are named.

The capture session is part of the project's settings. It's located in the Project window under the Project Settings tab.

You must enter a name and a destination folder for the capture. Conduit Live 2 will create a new folder for each capture. If a folder with the given name already exists, the application will append a number to the name, so existing files are never overwritten or modified.

Once the capture session has been set up, the "Start Recording" button at the top of the Project window becomes enabled.

Recording original streams vs. Rendered capture

There are two ways to record live video in Conduit Live.

For most applications it is recommended to record the original video streams. In this mode, the video data is saved intact in its original format, with no processing done by Conduit. While recording the original video data, you can preview effects using Conduit Live. After the shoot is done, you can deliver both the recorded video files and the effect setups to post-production, where they can be combined using either Conduit Live or one of the Conduit plugins (e.g. within Final Cut Pro or After Effects).

The other way to record video is to use the Rendered Capture node widget. This node widget can record anything: you can direct any video stream into it within the Project view, and the video will be recorded to disk as an image sequence. This can be used to record the output of a Conduit Effect node widget, for example.

Rendered Capture can be very processing-intensive, so if you don't need to specifically capture the output of an effect, you'll probably want to simply record the original video streams instead.

Recording original video streams

Conduit Live can record the incoming video stream from any live video input, such as a DV/HDV camera or a capture card.

In order to record something, you need to have at least one live video source in the project. In practice, this must be a Live Source (QuickTime) node widget.

By default, recording is not enabled for the Live Source node widget. In the Project view, click on the "Setup recording" button to specify in which format the video data should be written.

Two video formats are supported for recording:

  • QuickTime. This is exactly the original video data stored as a QuickTime (.mov) file.
  • DPX image sequence. This format is common in professional video/film post production environments.

Typically you'll want to choose QuickTime because it's the native format for the Mac OS X video capture system, and is compatible with a wide range of software. DPX may be more suitable in professional environments where image sequences are the standard way of transferring files to post-production.

Remember that you can always use Conduit Live to convert from one format to another, so this choice is not final. (For example, if you later discover that you need to have a DPX version of a video that was recorded in QuickTime format, you can load the movie into Conduit Live in Timeline mode and export as a DPX sequence.)

Using Rendered Capture

Rendered Capture is a node widget with a single input and no outputs. When a video stream is connected to its input, this node widget will write the incoming video to disk as an image sequence. When placed after e.g. a Conduit Effect, this can be used to record the output of an effect.

Rendered Capture supports alpha channels and high color depths. For example, you can record a keyed video with its alpha channel intact as a PNG sequence. You can also record 10 bits per channel DPX files at full precision.

Before enabling recording in Rendered Capture, you should specify the destination folder in the project's capture session settings (see above).
