The Ulead HD Plug-in equips videographers who own the JVC GR-HD1 and the JVC JY-HD10 camcorders with the tools to capture, edit, and output high-resolution HDV content within MediaStudio Pro 7, Ulead’s professional video editing software. Using the Ulead HD Plug-in, MediaStudio Pro 7 handles HDV content seamlessly without requiring additional tools or interfaces. The Ulead HD Plug-in is now available at <a href="www.ulead.com">www.ulead.com</a> for $299."

I purchased the Ulead HDV plug-in.

Well, I bought the new HIGH DEFINITION plug-in for ULEAD MediaStudio Pro 7.01.

I couldn't resist.

:-)

Now ULEAD MediaStudio Pro 7.01's VIDEO CAPTURE program features entirely new options.

Consequently, the plug-in seamlessly integrates with ULEAD MediaStudio Pro 7.0's VIDEO CAPTURE and VIDEO EDITOR programS.

When I click SETUP > DEVICE CONTROL, I now see a new "HDV 1394 Device Control" option.

In addition, when I open ULEAD MediaStudio Pro 7.0's VIDEO EDITOR program, I observe the standard NEW menu appear.

When I choose MPEG FILES in the EDIT FILE FORMAT drop-down list, I now observe new JVC HD-NTSC and JVC SD-NTSC templates.

Very cool.

Also - check this out.

The JVC HD-NTSC template features the following project settings:

NTSC drop frame (29.97 fps)
Overlay track(s):3
MPEG files
24 Bits, 1280 x 720, 29.97 fps
Frame-based
(MPEG-2)
Video data rate: 18300 kbps
Audio data rate: 384 kbps
MPEG audio layer 2, 48 KHz, Stereo

The JVC SD-NTSC template features the following settings:

NTSC double frame rate (60 fps)
Overlay track(s):3
MPEG files
24 Bits, 720 x 480, 59.94 fps
Frame-based
(MPEG-2)
Video data rate: 18000 kbps
Audio data rate: 384 kbps
MPEG audio layer 2, 48 KHz, Stereo

Frame-based would make sense in this case.

Some very interesting articles appear on the following JVC professional Web page:

The article at the bottom from TV Technology is especially interesting.

I noted the following excerpts:

"Another alternative is available from Ulead Systems, which has been editing MPEG in its native format for more than three years."

"As of Feb. 27, an HDV plug-in will be available for its Media Studio Pro 7 editing application for $299 that can capture the HDV transport stream and edit it on the timeline in MPEG as a program stream, "as if it were any other piece of video," says Travis White, product marketing manager at Ulead."

"We can decode the GOP and create new I-frames at the cut point. That gives you frame accuracy without first transcoding the MPEG."

"Because of the variable bitrate nature of MPEG, Ulead identifies the location of a cut point based on the time stamp, or presentation time, of the stream."

"Once there, they decipher the GOP and slice it where the edit is intended."

"Then Ulead's system decodes the GOP and re-encodes the last frame as an I frame to cap off the edit."

"That way nothing is lost, but the MPEG stream of HDV has been edited without the quality loss of transcoding."

My new JVC JY-HD10 professional model camcorder arrived yesterday.

I look forward to testing the HDV format and comparing it to ordinary DV25.
