With this setup, you can capture audio and video from a DV or HDV source. You can monitor the signal on a TV monitor while editing. Finally, you can export any sequence back to videotape.
With this setup you can capture audio and video from an SD-SDI, HD-SDI, or component video device (camcorder or VTR). You can monitor the signal on a TV monitor while editing. Finally, you can export any sequence back to the camcorder or VTR.
This setup requires either an SDI or component PCI card installed in the computer. Alternatively, it requires an external SDI or component device connected to the computer via FireWire. Either an internal card or an external device would provide ports, usually with BNC connectors, capable of receiving SDI or component video signals.
Some SDI and component PCI cards come with breakout boxes which provide ports for the SDI or component signals. Some breakout boxes also provide ports for genlock. Others provide the necessary outputs directly on the card.
Connect the serial device control port (RS-422 or RS-232) on the camcorder or VTR with the serial port (Windows) or USB port (Mac OS) on the computer. Use the Pipeline Digital ProVTR cable for RS-232/422-controlled devices.
If your system has a breakout box with a serial device control port (RS-422 or RS-232), connect the serial device control port on the device with this port on the breakout box. Do not connect the serial control port on the device with the serial or USB port on the computer. Some breakout boxes require a standard serial 9-pin D-Sub cable instead of the Pipeline Digital ProVTR cable. Consult the documentation from the manufacturer of the breakout box.
Native serial device control is available in Windows only.
With this setup, you can import or transfer audio and video files from card readers, drives, or tapeless camcorders recorded in any of the following digital video file formats:
a high-definition capture card,
a display card with component, SDI or HDMI outputs.
With this setup, you can capture audio and video from an analog camcorder or VTR. You can monitor the video signal on a TV monitor while editing. Finally, you can export any sequence back to the camcorder or VTR.
To convert the analog source signal to a digital file the computer can read, this setup requires an analog/digital (A/D) converter, or digitizer. You can use any of the following to digitize the video signal:
an internal digitizer, installed in the computer,
an external digitizer, connected to the computer,
a digital camcorder or VTR capable of digitizing an incoming analog signal.
Native serial device control is available in Windows only.
When you click ASIO Settings in the Audio Hardware panel of the Preferences dialog box, Premiere Pro opens the Audio Hardware Settings dialog box, which contains an Input tab, and an Output tab.
Determines which connected audio device is routed into and out of Premiere Pro. If the device is an ASIO device, select the ASIO drivers for the device. If the sound card does not have manufacturer-supplied ASIO drivers, choose Premiere Pro WDM Sound for this setting. To enable a device, be sure to install an up-to-date driver for the device (Windows.) If you want to input more than two stereo channels or monitor 5.1 surround audio, the device driver must comply with the ASIO (Audio Stream Input Output) specification. If it does not, only stereo inputs and outputs are available, regardless of the number of hardware inputs and outputs that are connected.
Specifies the size of the buffer, in kilobytes, that Premiere Pro uses for recording audio.
Device 32-bit Recording/Playback
On the Input tab, check Device 32-bit Recording to record audio in 32-bit samples. On the Output tab, check Device 32-bit Playback to enable 32-bit playback.
If you have trouble hearing audio, see the TechNote: “No sound during playback of video or audio clips.”
Select Sequence > Render Effects In to Out, or Sequence > Render In to Out. These commands are used you have set In and Out points to mark the area to render audio previews, rather than the work area bar.
Rendering audio previews could improve playback performance, but could take additional time when you select either of these commands.
You can set the length of preroll and postroll for clip and sequence previews in the General pane of the Preferences dialog box.
The Preroll and Postroll fields are different from the Preroll setting in the Device Control pane of the Preferences dialog box. The Preroll setting in the Device Control pane affects the control of external devices such as VTRs and camcorders.
When you edit a project, Premiere Pro uses disk space to store files required by your project. Premiere Pro stores captured video and audio, conformed audio, and preview files. Premiere Pro uses conformed audio files and preview files to optimize performance, allowing real-time editing, 32-bit floating-point quality, and efficient output.
All scratch disk preferences are saved with each project. You can select different scratch disk locations for different projects. If you reopen an earlier project after editing another project with different scratch disk locations, Premiere Pro will seek out the files belonging to the earlier project at the scratch disk locations you chose for that project.
If you delete preview files or conformed audio files for a project, Premiere Pro automatically recreates them when you reopen the project.
By default, scratch disk files are stored where you save the project. The scratch disk space required increases as sequences become longer or more complex. For best performance, dedicate a hard disk or disk strictly for your media assets. Choose a disk for the assets other than the disk where you keep your project file, operating system files, or the files for applications. That way your media disks can access and play media files as fast as possible, without having to access other files. Use the Project > Project Settings > Scratch Disks command to specify which disks Premiere Pro uses for media files. Choose scratch disks when you set up a new project.
In terms of performance, it’s best to dedicate a different disk to each asset type, but you can also specify folders on the same disk. You can specify unique scratch disk locations for each of the following types of files:
If you transfer video files to a scratch disk folder before creating the project for them, specify the folder containing the video files for Captured Video.
Audio files that you create using File > Capture, or by recording through the Audio Mixer as when recording a voice-over.
Files created when you use the Sequence > Render In to Out, export to a movie file, or export to a device. If the previewed area includes effects, the effects are rendered at full quality in the preview file.
Audio preview files are created by all of the following commands:
Sequence > Render In to Out
Use export to a movie file
Export to a DV device
If the previewed area includes effects, they are rendered at full quality in the preview file.
You set up scratch disks in the Scratch Disk pane of the Preferences dialog box. Before changing scratch disk settings, you can verify the amount of free disk space on the selected volume. by The amount appears in the box to the right of the path. If the path is too long to read, position the pointer over the path name. The full path appears in a tool tip.
My Documents (Windows) or Documents (Mac OS)
Stores scratch files in the My Documents folder (Windows) or Documents folder (Mac OS).
For optimum performance, follow these guidelines:
On Mac OS, disable journaling for best performance.
Specify your fastest hard disks for capturing footage and storing scratch files. You can use a slower disk for audio preview files and the project file.
Specify only disks attached to your computer. A hard disk located on a network is usually too slow. Avoid using removable media because Premiere Pro always requires access to scratch disk files. Scratch disk files are preserved for each project, even when you close the project. They are reused when you reopen the project associated with them. If scratch disk files are stored on removable media and the media are removed from the drive, the scratch disk is not available to Premiere Pro.
You can divide a single disk into partitions and set up partitions as scratch disks. However, partioning doesn’t improve performance because the single drive mechanism becomes a bottleneck. For best results, set up scratch disk volumes that are physically separate drives.
You can capture audio and video to separate drives, if supported by the format codec. (The native DV and HDV capture in Premiere Pro does not support capturing audio separate from video.) Set the locations for new files by choosing Edit > Preferences > Scratch Disks (Windows) or Premiere Pro > Preferences > Scratch Disks (Mac OS). If you don’t change the defaults, all files captured or created by Premiere Pro are stored in the same folder in which it stores the project files.

When Premiere Pro imports video and audio in some formats, it processes and caches versions of these items that it can readily access when generating previews. Imported audio files are each conformed to a new .cfa file, and MPEG files are indexed to a new .mpgindex file. The media cache greatly improves performance for previews, because the video and audio items do not need to be reprocessed for each preview.
When you first import a file, you may experience a delay while the media is being processed and cached.
A database retains links to each of the cached media files. This media cache database is shared with Adobe Media Encoder, After Effects, Premiere Pro, and Audition, so each of these applications can each read from and write to the same set of cached media files. If you change the location of the database from within any of these applications, the location is updated for the other applications, too. Each application can use its own cache folder, but the same database keeps track of them.
To move the media cache or the media cache database, click the respective Browse, button.
To remove conformed and indexed files from the cache and to remove their entries from the database, click Clean. This command only removes files associated with footage items for which the source file is no longer available.
Before clicking the Clean button, make sure that any storage devices that contain your currently used source media are connected to your computer. If footage is determined to be missing because the storage device on which it is located is not connected, the associated files in the media cache is removed. This removal results in the need to reconform or reindex the footage when you attempt to use the footage later.
Cleaning the database and cache with the Clean button does not remove files that are associated with footage items for which the source files are still available. To manually remove conformed files and index files, navigate to the media cache folder and delete the files.
By default, Premiere Pro renders video using the maximum number of available processors, up to 16. However, some sequences, such as those containing high-resolution source video or still images, require large amounts of memory for the simultaneous rendering of multiple frames. These sequences can force Premiere Pro to cancel rendering and to give a Low Memory Warning alert. In these cases, you can maximize the available memory by changing the rendering optimization preference from Performance to Memory. Change this preference back to Performance when rendering no longer requires memory optimization.
