TvidsNXS Software and hardware for real-time playout of Tvids video on HD-SDI Overview
TvidsNXS provides not only real-time playout for Tvids video sequences, it is a full software based digital intermediate workflow solution. TvidsNXS provides advanced capture and playback functionality and media import and export. TvidsNXS will control an external VTR for pull-ins and laybacks. Wide file format support, video monitoring tools and time line editing round out this powerful package. TvidsNXS is shipped with one of two PCI hardware cards (both for use in a Windows PC):
TvidsNXS software is a custom version of Drastic Technologies software with direct support for Tvids video sequences. It provides a bridge between the digital intermediate workflow and the real world. Capture to industry standard file types. Import existing files to a current format for playback. Create low res proxy files via export for logging and editing, and generate full resolution conforms for downstream processing and delivery.
Maintain project-based media pools and settings. Output via VGA preview for passthrough and output video plus a range of signal analysis tools (vectorscope, waveform monitor, and histogram), with built in metadata display.
Crash, Timed and Basic On Set Recording
For on set use, self incrementing shot and take numbers can be embedded into each record file and its metadata. Records may be added to the timeline upon creation, either at a specific location or at the end of the last recorded clip. Records may be 'crash' records with user-directed record and stop controls, or using a set duration. Recordings may be set to occur at set intervals for specified durations, including single frame recording for animation. Time of Day recordings may also be set up, using the system clock to automatically start the recording (and if desired a duration setting to end the recording). All recordings are made in their selected, native format. Please see the list at the bottom of this page to confirm specific file support. Any storage that provides enough speed and capacity can be used.
File Import and Export via Embedded MediaReactor
In From File
Import creates a series of new files in the specified format, ready for review, delivery or display. The new files are added to the Clip Bin so they will appear in the Thumbs and Clip views. A Preview features is offered to confirm the user has selected the right media (and a remove function if the clip does not need to be transcoded).
Out to File Output to File uses the Timeline to select the media which will be transcoded. A dialog arises to let the user set the format for the conversion, and sets an In and Out point to include the media which needs to be transcoded. Once the transcode is finished the resulting file will have media where there are clips, and black with silence where there are none. A Load and Save As dialog are present in the format setup to provide templates for the user's transcodes, so the user only has to set up the transcode once to use the same parameters at will. The template is also available to other TvidsNXS stations if it can be accessed on a network.
Clip Bin and Thumbnail View
The Thumbs view provides a picon and limited information about each clip, and offers dynamic features for the convenience of the user. Double clicking on the clip will load its details into an edit clip dialog. A right click option provides metadata display and edit options. You can add a clip to the Timeline or EDL by dragging and dropping. The Clips View provides more information about each clip, and offers a number of controls to work with the clip. The media can be removed (simply taken off the list but maintained), deleted (moved to the trash bin) or edited (have its in/out points trimmed). The clip may be duplicated to provide multiple instances for editing. The clip may be exported to various formats for delivery or alternate output.
Metadata
Metadata may also be accessed for a clip which has not been loaded. In Thumbs view, the user may right click on any clip's picon and select Metadata from the context menu. In Clips view the user may scroll to any clip and click on the word 'Metadata' to see the clip's metadata. Over a hundred metadata elements are maintained so any pertinent information that has been properly set will be accessible.
Timeline and EDL Editing
TvidsNXS projects maintain a cuts-only conform that may be viewed as a timeline or a traditional EDL (edit decision list). Clips may be added dynamically from the Thumbs view or Clip list. An Add dialog is available for clips not in the clip list. Clips are displayed on the timeline as a set of tracks, each of which display the track name. A picon is displayed for quick visual reference. Selecting the clip loads its details to the left of the timeline and allows the user to edit the In/Out points (trim the clip) and clip position on the timeline. An undo button is provided to remedy an incorrect action on the timeline. The timeline also provides the basis of the 'To VTR' direct to tape output as well as the file export. Timelines can be quickly generated by dragging and dropping clips onto the timeline, then moving them into place, and trimming as needed. Fine tuning of the timeline can be done in the time code edit boxes to the right of the timeline, making frame accurate changes a snap. When in the EDL view, all time code positions are editable in place, for maximum convenience. Clips are displayed on the EDL as a row, whose columns provide the parameters of the clip, such as the In/Out, Position, Path, Comment. Selecting the clip loads its details and allows the user to edit the In/Out points (trim the clip) and clip position oin the EDL.
Batch Control External VTRs In and Out TvidsNXS provides full control over an external VTR for frame accurate EDL based pull-ins and multiclip timeline based laybacks. Automatically create timelines through EDL batch capture. Exchange and edit timeline components for multiple distributables. Lay back the timeline in one pass and export a matching EDL. Preview individual edits or the whole EDL before running it. Adjusting edits is simple and non-destructive. Multiple lists may be saved whether they reference the same media or different media pools. TvidsNXS supports a wide range of standard EDL types so lists may be saved in the user's preferred format for ease of access and compatibility. Please note: TvidsNXS will not operate under serial control as would a production VTR. This feature is currently only supported in our full blown DDR products, such as the Titan Series DDRs and specific OEM software products such as Drastic DDR OEM.
Signal Analysis and Measurement
Built into TvidsNXS are preview, vectorscope, waveform YCbCr, waveform RGB and histogram displays. Single link or dual link (hardware-dependent), RGB or YCbCr and file monitoring are supported. These signal analysis and measurement tools provide a general reference to confirm input and playback signal levels, color balance and other information.
Signal analysis and review tools View the black and white levels, luminance, and chrominance, with alarms. Also view both chroma and luma using Drastic’s vectorscope and exclusive “Luma Stick”! Each of these signal analysis and review screens sit next to a scaled down VGA display of the clip (black & white for the wave form monitor) with dynamic features. Grabbing the VGA screen and pulling to the left or right will scroll through the clip at a rate relative to the speed of the user's action. Double clicking on the VGA toggles between cueing the first and last frame of the clip.

and also stored in a sidebar XML file so that no information is lost. Metadata may
be displayed for any loaded clip by selecting the Metadata View tab.
