EVTR is…

A next generation video solution appropriate for the digital broadcasting environment based on file.

Securing outstanding stability and flexible compatibility with the latest broadcasting network technology, it is the best video solution able to be utilized for a variety of broadcasting environment.

As an alternative video solution of Tape-based VTRs with Recording, Playing, and Editing, you can play the recorded video files and check them right away without any additional work with recording them in files.

Adding all the advantages with file-based systems in terms of space, time, man power and total cost, we strongly believe that KORAD eVTR becomes the best alternative solution for existing VTR.

10 Strong Points


1. Timeline-Based Recording : Simple Cut Editing

  • Visualize the recording work state by timeline
  • Make it easy & convenient to check the info of the recording work state, time, point of the work on timeline.
  • Simple cut editing is realized by setting In-out point, Pre-roll, Auto edit

2. Loop, Group, Segment, Multi-format Player

  • Video loop function on the player
  • Play multiple videos at once with a play list by Group function
  • Play a part of the full video by Segment function
  • Play videos in various formats in the project list in order

3. Multi-channel simultaneous recording : Generating files on the time-code

  • An eVTR treats multiple video source inputs at the same time
  • Easier edit, keeping the time-code identical from a variety of video sources

4. NLE/MAM Interlock – Workflow Improved

  • Interactive Import with videos from eVTR and clips from NLE
  • EDL generated from eVTR can be imported to NLE
  • Searching for and utilizing materials registered in MAM through eVTR search engine.
  • Materials from eVTR can be registered in MAM right away

5. Editor/Controller Interlock – The Same Production Circumstance with VTR

  • Interlocking with Fastrack and Sony Editor, recording process is under the identical producing circumstance with VTR

6. Consolidation

  • Consolidation – generating a video file inserting new video clips between pre-recorded videos on the recorder (Faster and more effective editing)

7. Time-code Marking (VITC)

  • Inputting Time-code of the video clip to VITC(Vertical Interval Time Code), time information of it can show up on a broadcasting SDI monitor

8. Gathering NG cuts only

  • Offer functions to classify into video information of recording-failure part(NG) (Helpful for researching NG cuts and utilizing them)

9. Record/Play/ONAIR-Tally through GPIO

  • Interlocking with VMU by GPIO board
  • Record and play control of eVTR through VMU
  • ONAIR-Tally, reporting on recording

10. Standard Broadcasting Formats

  • Support standard broadcasting formats widely known to broadcasters
  • Codec : XDCAM, DVCPRO HD
  • Wrapper : MXF, MOV
