Exporting a File in K2 Clip Format

You can export a project as a K2 Clip format file.

Before performing these steps, you must configure the connection to the K2 Media server you want to use as the export destination.

K2 Server (SAN) Settings

Note
1Click [Export] on the Recorder.
2Click [Print to File].

The [Print to File] dialog box appears.

[Print to File] Dialog Box

Alternative
3Click [K2] on the category tree.
4Select an exporter, and click [Export].

Select an exporter from [K2 DV Clip], [K2 DVCPRO HD Clip], [K2 AVCIntra Clip], [K2 D10 Clip], [K2 MPEG2 Clip], [K2 AVCHD Clip], [K2 DNxHD Clip], [DV GXF], [DVCPROHD GXF], [AVCIntra GXF], [D10 GXF], [MPEG2 GXF], or [JPEG2000 GXF]. Exporters that do not support the project settings will not be displayed.

5Configure the settings such as the clip name or export destination.

K2 Clip Exporter Settings

6Click [OK].

The icon indicating that the system is generating a file is displayed on the clips that are being exported in the source browser.

K2 Clip Exporter Settings
Common settings
[Clip Name]

Enter a clip name for the file to be exported.

[Destination]
[Server]

Select a file export destination from the list.

K2 Server (SAN) Settings

[Bin]

Displays the list of bins in the save destination you selected in [Server]. Select the bin to register captured clips.

[Overwrite file when it exists]

Check this item to overwrite a file if any file with the same clip name is already registered in the bin in the export destination.

[Sequence settings]
[Export as a program sequence]

Check this item to export sequences as programs.

[Audio Settings]
[Channels]

Select the number of audio channels you want to export from the list.

[Quantization Bit Rate]

Select an audio quantization bitrate from the list.

[Ch 1&2] - [Ch 15&16]

Select the channel to output bitstream when outputting audio with the audio bitstream retained.

Video settings

[Video Setting] is displayed depending on the exporter. For more information on the settings for each exporter, refer to the following.

Video settings — DV
[Format]

Select an export format from the list.

Video settings — D10
[Bit Rate]

Select a bitrate from the list.

Video settings — AVCIntra
[Format]

Select an export format from the list.

Video settings — MPEG2
[Format]

Select an export format from the list.

[Segment Encode]

Check this item to export a clip of a raw source without re-encoding.

This increases the output speed.

[Quality/Speed]

Select quality from the list.

[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 [Maximum] lists. You can also enter a value directly.

[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].

Video settings—DNxHD
[Bit Rate]

Select a bitrate from the list.

Video settings—AVCHD
[Profile]

Set the profile. The selectable profiles will differ depending on the frame size to be exported.

[Bit Rate Type]

[CBR] assigns a constant number of bits. Although noise, etc. may be present, the encoding process is made quicker.

[VBR] changes the assigned bitrate 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.

[Average ]

Set this item if [CBR] or [VBR] has been selected as the bitrate type. You can either select from the list or enter values directly.

[Max]

Set this item if [VBR] has been selected as the bitrate type. You can either select from the list or enter values directly.

[Quality]

Set this item if [Quantization] has been selected as the bitrate type. Select the image quality from the list.

[IDR Interval]

Enter the IDR frame interval, and set the GOP size.

[B Frame]

Set the number of B-frames included in one GOP.

[Multi Slice]

Check this item to divide 1 frame into 4 parts. If the decoder supports multi-slicing, the decoding may be made quicker.

[Entropy Coding Mode]

Select the H.264 encoding mode.

[Number of Reference Frames]

Set up to how many frames should be considered when motion estimation is performed.

[Motion Estimation Precision]

Select the unit of division for the motion estimation block from the list.

[Minimum Block Size of Prediction]

Set the block size during motion estimation for intra-frames/inter-frames.
