[Settings - MPEG2 for K2 Clip] Dialog Box
[Bit Rate] Select a bitrate type.
[CBR] sets a fixed transfer rate, allocating a fixed number of bits during the encoding process.
Select a bitrate from the [Average] list. You can also enter a value directly.
[VBR] sets a variable transfer rate, altering the number of assigned bits according to the
complexity of the movement or image quality. Compared with [CBR], the media volume can be
used more efficiently, and this enables more consistent image quality overall. Select a bitrate
from the [Average] and [Max] lists. You can also enter a value directly.
[Quality/Speed] Select quality from the list.
[GOP Structure] For MPEG, a certain number of frames is considered as a group, and operations such as
compression/enlargement and cut editing are performed on a GOP basis. A GOP comprises
“I frame”, “P frame” and “B frame”. The I frame allows images to be reproduced independently,
the P frame is for recording and reproducing only the differences with the preceding image,
and the B frame reproduces images from the differences in the preceding and following
images. Select I, P and B frame patterns of the GOP from the list. Normally, select [IBBP].
[I-Frame Only] is comprised of only I-pictures. Editing is made easier, but the amount of data
increases in size.
[Picture count] Set the number of frames included in a group.
[Closed GOP] Check this item to complete information within each GOP. Although the amount of data
increases, the video can be re-edited using software that supports GOP-based editing.
Normally, leave this item unchecked.
[Chroma Format] Select a YUV pixel format from the list.
[Profile/Level] Select a profile & level. If [Chroma Format] is [4:2:0] and [4:2:2], the profile will be set to Main
Profile and 422Profile, respectively. The level for SD image quality will be Main Level, and
the level for HD image quality will be High Level. The profile & level changes according to the
format selected in [Chroma Format].
Capturing in K2 Clip Format
Capture sources in K2 Clip format.
3 Note
f Analog devices or devices that are connected via an HDMI terminal cannot be controlled from EDIUS. When you capture sources from
a device that does not support deck control by EDIUS, you need to cue up to the part you want to capture beforehand.
1)
Click [Capture] on the menu bar, and click [Select Input Device].
f The [Select Input Device] dialog box appears, and the list of the device presets you registered in the system settings is displayed.
2)
Select a device preset that supports capturing in K2 Clip format, and click [OK].
f The [K2 Ingest Setting] dialog box appears.
“[K2 Ingest Setting] Dialog Box” (w page 439)
3)
Configure the settings including the save destination and reel name for the source to be captured,
and then click [OK].
f When you capture sources from a device that supports deck control by EDIUS, you can operate the camera using the operation buttons
on the Player.
f When you capture sources from a device that does not support deck control by EDIUS, proceed to step 5).
4)
Play back the source to capture, and set the In and Out points.
