Camera, faces and emotion

In an action scene, 3.0 followed the instruction for the camera to briefly lose orientation after an explosion and then recover.
The reviewer recalls plasticky-looking emotion in 2.6 and finds the acting in the 3.0 emotion test much more natural.
With an extra face reference, the 3.0 character turns toward camera without obvious morphing; the reviewer contrasts this with a recurring 2.6 issue when the face was absent from the starting frame.

Dialogue and sound

The reviewer explicitly returns to dialogue as a weakness of 2.6 and tests a multi-shot conversation in 3.0.
In the result, he notes accurate lip sync, consistent faces across angles and a substantial improvement in speech/dialogue over 2.6.
In a separate 2.6 test, a rooftop chase followed the requested camera direction and produced matching footsteps, wind and the final pigeon sound.

Product differences independent of review opinion

Independent of subjective test preference, the Mixer AI workflows are materially different: 3.0 adds Multi-shot, Elements, a second possible input image and 4K while also extending the clip length. Those are current product facts.

10 seconds on 2.6 versus 15 on 3.0.
Multi-shot and Elements are exposed on 3.0.
4K is listed on 3.0; the current 2.6 KB spec does not list a 4K output mode.
