I have CS6, mac os10.6.8.
I am importing mxf files from canon xf100. Once in timeline, I am simply applying effects such as b + w or fast color corrector, with no modifications or changes yet made to footage. I just downloaded the most recent update - no changes. Thank you.
After the application of the Effects, are you Rendering your Clips for smoothest playback - Return/Enter key?
Once you have applied the effect, you have made a change that will affect the playback. If the colored status bar above the clip is red, Pro is telling you that it doesn't have the resources to nake the playback smooth. You fix this by rendering the clip. Some effects affects do not use the MPE acceleration. The effects list dialog indicates which effects have been enhanced in this manner.
