Specifies IDR-frame interval in terms of I-frames See also description of i_adapt and b_adapt. Otherwise, the encoder can adapt the GOP structure for better efficiency, whose range is constrained by keyint, bf parameters etc. The encoder must strictly follow the given GOP structure as defined by keyint parameter, bf etc. This flag does not affect long-term reference frames. The AVC encoder ignores this flag if idr_interval is set to 0, i.e.

Frames subsequent to the first frame of GOP in display order do not use frames from previous GOP as reference. In this GOP frames prior to the first frame of GOP in display order may use frames from previous GOP as reference. The encoder generates open GOP if this flag is not set. Maximum number of B frames between non-B-frames.įrames in this GOP do not use frames in previous GOP as reference. Number of pictures within the current GOP (Group of Pictures).

0 - Unspecified codec level, determine the correct level from other sources, such as resolution and bitrate.

Set async_depth=1 to low latency encoding. Specifies how many asynchronous operations an application performs before the application explicitly synchronizes the result. Specifies the codec profile use it explicitly or the Quick Sync functions will determine the correct profile from other sources, such as resolution and bitrate. The actual number of supported target usages depends on implementation. The application can use any number in the range. It's mapped to target usage and indicates trade-offs between quality and speed.

In the encoder settings dialog box you can add any of the parameters described below. It's similar to previously described libx264 encoder settings but it has its specifics. Now let's see what parameters you can use there in order to control encoding process. As you see, it takes just a few clicks to use Quick Sync as encoder.
