DrasticPreview - Audio/Video/Metadata Player

DrasticPreview Professional Media Player

DrasticPreview is a professional media player for formats used in the broadcast and production industries. DrasticPreview supports today's most important file types, and includes a number of others we've added over the years. This innovative software allows the user to view their files on a VGA/DVI monitor without tying up the native, or even compatible (typically in high demand) production or broadcast device or application. Play media for collaborative and review applications, scene marking and EDL construction. Play media stranded by failed or unavailable legacy devices or applications. Play all your files from one station, using one application.

90 Seconds with DrasticPreview

The main GUI offers a full range of transport controls for forward and reverse playing and cueing, displays time code and audio levels, playback mode, and file name, and shows a slider to indicate the current position within the clip. The on-screen viewer window may be scaled to effectively accommodate varying viewing requirements, including a full-screen mode.

Media can be selected through a standard browse approach, or dragged and dropped onto the display window. Once loaded, the clips may be played or viewed in various playback modes, including normal, looping, and palindromic. DrasticPreview provides a full range of keyboard/number pad commands for transport control and other settings, and window resizing including zoom and pan controls.  Cut, copy and paste (CTRL+X/C/V) or time code is also available for moving time codes to text documents, spreadsheets or TCCalc.  Pasting time code will automatically seek the file to that point.

Transport Controls and Displays

Track Info Data

Media file track info including size, frame rate, bit rate, audio sample frequency and rate, codec/fourcc and channels

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

Time Code Data

Time code display showing frame value, absolute (zero based) time code, VITC, LTC/SMPTE, User Bits and extended 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 display, showing the media files internal metadata (comments, descriptions, camera, gps coordinates, serial, device, edit data, url, etc)

The Metadata window may be selected by pressing the Metadata button on the GUI - this section displays over a hundred metadata elements with information specific to 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

Play list containing all the tracks to be played in order, or random access by double clicking on entries

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.

Zoom and Pan

Video playback on in the application fully supports zooming and panning the video in still or playback.  Using the scroll wheel of the mouse the image can be zoomed out to cover a small part of the screen, or zoom in to closely check individual pixels.  Left clicking and dragging will move the image to view different parts while zoomed in.  Clicking the right mouse button will fill the application with video, and clicking the middle button will set the image to pixel for pixel (where every image pixel is exactly one screen pixel).  Zoom is available in windowed or full screen mode.

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 overlaid. The user may select between available time code sources by clicking on the time code source field.  Copy and pasting of time code is also available by using <ctrl>-c and <ctrl>-v

Closed Captioning

DrasticPreview supports 608/708 Closed Captions. The closed caption information will be displayed over the video frame when enabled.  Supported sources include SMPTE 436, CEA-708, OP-47/RDD-08, CEA-608, MCC, AAF, SCC, STL, EBU, embedded and many other formats. See the caption section below for more details.

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.

Audio Channel Selection

DrasticPreview generally supports stereo audio output, however any channel pair of up to 16 available in the file can be selected for playback.  For up to 16 channel simultaneous playback, please see DrasticPreview Pro.

SDK and APIs

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.

MXF Player

With the huge variety of MXF formats and sub formats, DrasticPreview makes an excellent general player due to its wide compatibility with all MXF types, standard and non standard

Closed Caption Check

DrasticPreview can display CC1, CC2, CC3 and CC4 closed captions from a wide variety of sources (a list is available here) directly over the video, providing an easy way to check closed captions in files before they go to the server

On Set File Check

Because DrasticPreview supports capture formats like RMF (Canon/Gemini/Codex), DNG (Blackmagic/OneCam), ARI (Arri/Codex), CINE (Phantom/Miro/Flex), MXF Raw F65 (Sony), MXF XAVC (Sony), MXF HDCam/XDCam (Sony), MXF P2 (Panasonic), MXF Avid (Avid/Ikegami), AVCHD (Canon/JVC/Panasonic/Sony) it makes an inexpensive add on for checking file metadata, audio, video and consistency from copy.

Pre Air Confidence Check

With support for all major server file formats (including LXF), DrasticPreview can be used to check files before they are actually copied to the server.  This can avoid expensive and time consuming server crashes and bad or incorrect files from going to air

Production Assistant Data Collection

DrasticPreview is the most cost effective way for files to be catalogued and checked on laptops or other low end machines by production assistants, which save the expensive systems for editing and finishing.
