We're seeing that software rendering for a generator is extremely slow. All these are on a Motion 5 project at 1920x1080, 29.97fps, progressive at full res.
step 1: checking timing on our plug-in
Drawing takes 10-11ms
RGBA->ARGB conversion takes 20-28ms
Motion playback rate is 10-11fps
step 2: removing RGBA->ARGB code
Motion playback rate is still 10-11fps
step 3: removing ALL code from renderOutput method
Motion playback rate is 12fps
step 4: changed from software to hardware rendering, still with empty renderOutput method
Motion playback rate is 30fps
So even before we add any custom code we're hampered by using software rendering, and this is just a simple generator with an output only not a filter with input/output.
Thoughts?
