AJA Adobe Plugins v12.4
Video Format The default setting (expected to be what most users will want and use) is Match
Sequence. When Match Sequence is selected, the transmit plugin will try to put the card in
a mode that matches the resolution and frame rate of the timeline you're working with.
Alternatively, you can use Match Control Panel and then select a “hard-wired” video
format from the AJA Control Panel menu of available formats.
NOTE: Even with Match Sequence selected you can make other parameter adjustments (such as
color space or up/down/cross conversions) using the AJA Control Panel.
Offset Settings: The AJA Transmit plugin always works to perfectly sync audio and video output from the
AJA hardware. In doing this, a buffer is created which may cause a slight delay (generally
around 1-2 frames) compared to the Program Monitor or Source Monitor on your
desktop. These Offset settings have been provided by Adobe to tweak that delay, and
match up the video on the desktop to the video and audio coming out of the AJA
hardware.
IMPORTANT: A video offset set here can cause a missed frame when laying off to tape. Be sure to set
this offset to zero before layoff (refer to your AJA Mac or Windows release notes for the latest
information).
Buffer Mode Use the Buffer Mode menu to choose Standard, Minimum, or Maximum frame buffering.
This mode determines how many frames of buffering are to be used in the AJA hardware:
• Standard, will store 8 frames
• Maximum will store the maximum number of frames allowed by the given hardware
• Minimum will store 3 frames
Minimum vs. Standard Mode: The Minimum setting will provide the best scrubbing and JKL keyboard control
performance on the timeline. The Standard setting insures that frame drops are less
likely by providing more frame buffering.
For editing, KONA and Io users should use Minimum mode most of the time. Then, when
mastering a tape or playing out live (to air or theater) where no scrubbing will occur, you
can switch to the Standard mode to avoid frame drops.
For T-Tap users, Standard mode is preferred in both cases.
Use Standard mode for any projects in which the sequence framerate does NOT match
the framebuffer framerate. The most common examples of this are using 720p23.98, 25,
and 30. These formats don’t exist on SDI so the card will switch to 720p50 or 60
automatically. Users, in these cases, should use the Standard buffer mode.
Widescreen Checkbox Check the Widescreen box if the project is widescreen standard definition NTSC or PAL
format.
Legacy AJA Preview
Plugin
The Legacy Preview plugin allows you to view the current frame of your working timeline
in various formats on a monitor connected to a KONA/Io output.
Video & Pixel Format: Use the AJA Control Panel to set Video Format and Pixel Format for your desired output.
After Effects does not set these parameters within the application.
Source Frame Setting: To set up Preview options for After Effects, go to the Window menu and select AJA
Preview.
