Extron Electronics JPEG 2000 Encoder - Manual (Page 16)

5. Beside the Video Folder field, click the button to navigate to the folder (or the
previously mapped drive) containing sequential image frames (BMP, DPX, PNG, TGA,
or TIFF) that are to be encoded. The path for the selected folder appears in the
Video
Folder field.
NOTES:
• When selecting and opening a folder in the Browse for Folder dialog box,
the files within the folder are not displayed.
• All of the image files in this folder are included in the encoding process.
Ensure that only the required files are placed in the selected folder. Audio
files or files of a different type are not encoded.
TIPS:
• The encoder processes image files with 8 bits per color channel, but use
of source material with a bit depth as low as this may result in visible
contours in areas of the image with subtle graduation (for example,
clouds).
• The files should be located on a local drive for better performance.
• For best results, use uncompressed, progressive file formats with the
highest bit depth. Uncompressed TIFF files with 16 bits per color channel
are ideal. DPX files with 10 bits per color channel are the next best option.
You can also adjust the settings for audio sources in the Inputs section of the Encode
Settings tab.
NOTES: • The JMP 9600 JPEG 2000 Media Player supports encoding only even pairs of
audio and produces an MXF wrapped audio track consisting of 2, 4, 8, or 16
channels of audio. This is combined into the DCP with the video.
• Audio files must be uncompressed PCM (WAV) files sampled at 48 KHz and
16, 20, or 24 bits.
The JPEG 2000 Encoder offers two options for handling audio input content:
z Single Audio File — The single audio WAV file can be composed of a stereo pair
of audio channels or an even number of audio channels (up to 16 channels of audio
content).
NOTE: The lite version of the JPEG 2000 Encoder application supports one file
consisting of a stereo pair or two channels of audio.
z
Multiple Mono Files — The JPEG 2000 Encoder processes up to 16 separate WAV files
from up to 16 separate data storage locations. This allows you to dedicate specific audio
files to corresponding audio channels according to multi-channel audio requirements for
theaters (DCI).
To select a single audio file:
1. From the Tasks menu, select Encode .
2. Select the Encode Settings tab.
3. Below the Audio Files field of the Inputs section, select Single Audio file .
4. Beside the Audio Files field, click the button and navigate to the folder
containing the audio (WAV) content to be encoded.
5. Select a file from the folder and click Open . The path for the selected file appears in the
Audio File field.
