When this option is enabled, the Unreal Engine does not generate any new frames of output until the AJA card is ready to accept the new frame. The effect is similar to genlock, but instead of locking the Unreal Engine's frame rate to an input signal, it locks the Engine's frame rate to the output timing of the AJA card.

This option is most useful when you don't already have an input signal that you can lock the Unreal Engine's frame rate to, but you want to ensure that the Engine is producing only one output frame for every frame in the output video feed.

AJA Media Source Settings

AJA Media Output Settings

Configuration Options

Other AJA Options

Device

Sets the AJA device that this Media Source will use to bring video into the Unreal Engine. If you have multiple cards or devices attached to your computer, you can choose which one to use here.

Source

Sets the port or SDI connection on the specified device that this Media Source will use to bring video into the Unreal Engine. Note that only single-link connections are supported.

Resolution

Sets the resolution of the incoming video feed. Note that this must match the actual video feed exactly.

Standard

Sets whether the incoming video feed is progressive or interlaced. Note that this must match the actual video feed exactly.

Frame Rate

Sets the number of video frames per second in the incoming feed. Note that this must match the actual video feed exactly.

Timecode Format

Specifies the type of timecode that accompanies the video signal.

Capture with Auto Circulating

Captures video, audio, and ancillary data at the same time. This may decrease your transfer performance, but it guarantees that all data for each frame will be synchronized together. If you experience problems with latency, you can try disabling this option.

Capture Ancillary

Determines whether the Unreal Engine captures ancillary metadata that accompanies the video signal.

Max Num Ancillary Frame Buffer

Sets the maximum number of frames of ancillary data the Unreal Engine will store in memory at any given time. If the input video jumps or hitches, you can try raising this value.

Capture Audio

Determines whether the Unreal Engine captures audio from the Media Port.

Audio Channel

Specifies the audio channel that contains the signal you want the Unreal Engine to capture.

Max Num Audio Frame Buffer

Sets the maximum number of frames of audio data the Unreal Engine will store in memory at any given time. If the input video jumps or hitches, you can try raising this value.

Capture Video

Determines whether the Unreal Engine captures video from the Media Port.

Color Format

Determines the order of the color channels that make up each pixel in the input video, and the number of bits in each channel.

Max Num Video Frame Buffer

Sets the maximum number of frames of video data the Unreal Engine will store in memory at any given time. If the input video jumps or hitches, you can try raising this value.

Log Drop Frame

When enabled, the Unreal Engine prints a message to its output log every time it detects a dropped frame in the input feed.

Encode Timecode in Texel

When enabled, the engine embeds the timecode of each frame into the captured video. You can use this to check that the timecode for each frame of input matches the values you're expecting. See Timecode Texel Encoding.

Synchronize with Engine's Timecode

By default, the Unreal Engine attempts to play the video frames as they come in. Enable this setting to buffer incoming frames, and try to align them with the Unreal Engine's internal timecode. If the timecode of any buffered frame matches the Unreal Engine's internal timecode for any frame, the video input will be synchronized with from that frame forward.

Player Overrides

Leave these options at their default values for AJA Media Sources.

Output Type

Determines whether the Unreal Engine outputs only the fill image, or both the fill and key images. When you set this to Fill Only, only the fill image is output to the Source set below. When you set this to Fill and Key, the fill image is output to the Source, and the key is output to the Key Source.

Device

Sets the AJA device that this Media Source will send its video feed to. If you have multiple cards or devices attached to your computer, you can choose which one to use here
