Transport Controls

The Transport Controls offer the following functionality:

• Position Bar and Slider - Click on any point on the slider to instantly cue that relative point in the file, or 'grab' the pointer and drag it to quickly scrub through to find a particular scene
• Fast Reverse - Play the file in reverse at the fastest possible speed
• 5 Seconds Back - Cue the frame 5 seconds before the current location (or the beginning if less than 5 seconds from the first frame)
• 1 Frame Back - Cue the frame immediately before the current frame, useful for finding a specific location
• Reverse Play - Play at -100%, or normal speed in reverse
• Pause - Stop playback and display the frame at the current location
• Stop - Stop playback and cue the first frame
• Play - Play at 100%, or normal speed
• 1 Frame Forward - Cue the frame immediately after the current frame, useful for finding a specific location
• 5 Seconds Forward - Cue the frame 5 seconds after the current location (or the end if less than 5 seconds from the last frame)
• Fast Forward - Play the file (forward) at the fastest possible speed

Track Info Data

The Track Info data window may be selected by pressing the Track Info button on the GUI - this section displays:

• Duration - both in current time code type (HH:MM:SS:FF) and as a total number of frames
• FPS - frames per second to two decimal places
• Width - in pixels
• Height - in lines (for both fields if interlaced)
• Bit Depth - per pixel or per component
• FourCC - video codec information
• Bit Rate - overall rate of the file in bits
• Video Channels - video channels bit array
• Audio Codec - audio fourcc descriptor
• Audio Channels - audio channels bit array
• Audio Frequency - samples per second
• Audio Bits/Sample - how many bits in an audio sample

Time Code Data

The Time Code data window may be selected by pressing the Time Code button on the GUI - this section displays:

• TC (time code) - Absolute position
• LTC Frame - Longitudinal (SMPTE) time code
• LTC Ub - Longitudinal (SMPTE) user bits
• VITC Frame - Vertical interval time code
• VITC Ub - Vertical interval user bits
• DATA 0 - user data or size (4 bytes)
• DATA 1 - user data or pointer (4 bytes or greater) Basic Elements

Time code type is specified by the last separator:

• : (colon) = Non drop frame
• ; (semicolon) = Drop frame
• - (dash) = 24 FPS (FILM)
• . (period) = 25 FPS (PAL)

Metadata

The Metadata window may be selected by pressing the Metadata button on the GUI - this section displays over a hundred metadata elements with information addressing the many facets of each media file's existence, and in some cases the attributes of a selected track, or stream. For a complete list of metadata fields, see the Drastic Metadata page.

Play List

The Play List window may be selected by pressing the Play List button on the GUI - this section allows the user to set up a list of files, or clips. Each file that is opened is added to the Play List, and files can also be added by a drag and drop operation. Once in the Play List all of the clips may be played in sequence, starting with the clip the user double clicks on.

Time Code Display

A dedicated time code field not only displays the current time code location but allows the user to enter a known time code location within a selected clip, and press Enter to cue that frame. In Full Screen mode, an optional time code display may be overlayed. The user may select between available time code sources by clicking on the time code source field.

Closed Captioning

DrasticPreview supports 608/708 Closed Captions. The closed caption information will be displayed over the video frame when enabled.  Supported sources include:

• MPEG-2 'user' CC
• MXF SMPTE 436
• MXF Avid embedded CC
• MCC files side bar MacCaption/PC-Caption
• SCC files side bar MacCaption/PC-Caption
• MOV SD/HD CC tracks

Please note:  The CC feature is only available when running under a temporary or permanent license.  Please contact Drastic if you want to test this feature.

DrasticPreview is based on two Drastic APIs that are available to third party developers: DrasticPreview Pro - HD-SDI media preview player 

• DrasticPreview SDK - A full preview engine from reading the file to playing out to audio devices, memory planes or OpenGL surfaces.  More information is available here.
• DTMediaRead SDK - Integrate all the file types we read into your own application.  Read uncompressed audio and compressed or uncompressed YCbCr 10, YCbCr 10, RGBA or RGB 10 frames.  More information is available here.
