1. How can I get Grass Valley EDIUS Pro/Broadcast Version 4?
Please visit the Upgrades page to get more information on how to order either an upgrade or full version.

2. What is the difference between EDIUS Pro and EDIUS Broadcast?
EDIUS Broadcast incorporates all the features and workflow of EDIUS Pro, but adds additional modules to allow you to capture, edit and output to the following formats:

  • Grass Valley Infinity™ JPEG 2000
  • Panasonic DVCPRO® 50
  • Panasonic DVCPRO HD
  • Panasonic VariCam®
  • Panasonic P2
  • Panasonic AVC-Intra*
  • Sony XDCAM®
  • Sony XDCAM EX

You can upgrade from EDIUS Pro to EDIUS Broadcast at any time.

* Also requires the AVC-Intra plug-in for EDIUS Broadcast, available separately.

3. Does EDIUS Pro support 24p editing?
Yes. EDIUS Pro (v3.6 and higher) features project presets for true 24p editing, compatible with the various 24p formats offered by leading camera manufacturers.

4. Why is a very powerful PC needed for HDV editing?
To edit in HD resolution, the full image size for each frame of video can be as high as 1440x1080, which is approximately four times the size of an SD resolution image. When editing in HDV, the system is required to decode the compressed stream (MPEG or Canopus HQ) and apply effects to the full size image. This process requires a fast CPU and also fast memory access speeds.

5. Is it possible to edit HDV with EDIUS Pro on a laptop or lower-end PC?
Yes. EDIUS Pro can be installed on laptops and lower-end PCs for HDV for editing, but the realtime editing features will be very limited — effects may need rendering for smooth playback and output. Depending on the system's graphics card performance, Xplode transitions may not work in HD resolution (requires a minimum of 128MB graphics memory).

6. I am having problems with activation, as my machine is not connected to the Web. How can I activate it?
Detailed steps on how to activate EDIUS from a separate PC are available from the main support section on the Web site.

7. When running EDIUS Pro, I do not have any video overlay. What could be the problem?
The graphics card may not be adequate for editing in the particular format/resolution. HD resolution editing requires a minimum of 128MB graphics memory. For a list of compatible graphics cards for EDIUS Pro, check the compatible hardware listing or contact Technical Support at the nearest Canopus office.

8. How many layers of HDV can I do in real time?
A dual Pentium 4 Xeon 2.8GHz system can edit two to three layers of Canopus HQ HD clips in realtime. If using native MPEG-2 TS format HDV clips, typically only one layer can be edited in realtime. In addition to CPU speeds, realtime performance is also dependant on hard disk and memory specifications.

top

9. What is the difference between native HDV and the Canopus HQ codec?
The Canopus HQ codec is an intra-field compression codec (which means that the compression is kept within each field), compared to the interframe coding of native MPEG-2 TS (which means that a certain number of frames are grouped together when compressing). Using MPEG-2 TS will allow for higher compression, but decoding the frame, as well as trimming the frame, will require more CPU power and additional processing of surrounding frames.

top

10. Why should I use the HQ codec?
Editing in HQ provides faster, more responsive editing with increased realtime capabilities, while sustaining the original image quality.

top

11. Is there any loss in quality with the HQ codec?
Since the specification of the Canopus HQ codec incorporates the same resolution and luma sampling, with increased chroma sampling as compared to HDV, the image quality is sustained when converting native MPEG-2 TS data to Canopus HQ.

top

12. Can I use NTSC and PAL footage together in the same project with EDIUS Pro?
Yes. EDIUS Pro can edit in realtime any mix of NTSC, PAL, 1080/60i, 1080/50i, 1080/25p, 1080/30p and 720/30p clips on the same timeline, and output to the format selected when creating the project.
