Frame Processing

NOTE: Frame processing is not supported in Speed Ramp Mode. For more information, go to Speed Ramp Mode.

Frame processing allows for the combination of multiple captured frames into one recorded frame. The combination occurs before the resulting frame is encoded. You can select the following frame processing settings: No Frame Processing, Frame Summing, Frame Averaging.

When in Frame Summing mode or Frame Averaging mode, the current integration time is applied to each frame. This means if the integration time is not the entire frame time (or 360°) there are gaps between the images used to create the combined frame. This may lead to unexpected motion artifacts.

The effect of frame processing is only visible during record. In Frame Summing mode, this means the exposure changes between preview and record. Experiment with the exposure and frame processing settings to achieve the effect you want.

No Frame Processing

Normal frame processing mode. The Frames to Process selection does not affect recording.

Frame Summing

Frame Summing combines the specified number of frames into one frame, and adds together the exposure time for each of the original frames. The resulting frame has an effective integration time that is equal to the current integration time multiplied by the number of frames.

For example, if you select 16 as the Frames to Process value, and set exposure to 1/48 sec, the resulting image has an effective integration time of 1/3 sec (16 x 1/48).

Frame summing results in a final image that is brighter and possibly blurrier than any of the original frames, so you can use frame summing to achieve the effect of long-exposure.

Frame Averaging

Frame Averaging combines the specified number of frames into one frame, and averages the exposure time for each of the original frames. The resulting frame has an effective integration time that is equal to the current integration time.

For example, if you select 2 as the Frames to Process value, and set exposure to 1/48 sec, the resulting image still has the exposure value of 1/48 sec, along with the effect of long-exposure.

You can use frame averaging to achieve the effect of long-exposure along with the benefits of reduced noise. However, frame averaging does affect motion blur characteristics.
