Thanks for chiming in Dave.

[JonZ MarZ] “move the already created masked tweens in the subsequent already created keyframes without altering the animation”
I’m not clear on what you mean. How can you move something without altering the animation?

Could you post a screen capture of your timeline and composition. Once selected, normal behaviour is that keyframes remain selected and respond to the transform.

Interesting, this has not been my experience at all. When I’m rendering a file that After Effects estimates will take a a few hours, I’ve found that when switching to work in Final Cut or similar the performance in the foreground application slows down when there are fewer CPU’s available for other apps.
I’m on a 12 core MacPro with 64GB of RAM, OS 10.8.5 if that’s relevant.
-
Sorry Eric, my point was that setting the available CPU’s to zero assumes that while After Effects is rendering there are no other processes competing for CPU time.
I frequently start a render then proceed to work on something else.

Free-transform mode may help you.
First select all pertinent mask keyframes then use free-transform to modify them in unison.

[Tom Lansford] “neither AE nor PP can read the mxf file…”
My apologies. I’m on a Mac and assumed that DNxHD 444 would work for you since it does contain alpha. I routinely use the ProRes 444 codec for QuickTime.
If you are unable to use QuickTime and ProRes another option is to use a TIFF or Targa sequence as both of these support Alpha.
Is there a reason you prefer not to render directly from After Effects and need to use Media Encoder?

[Tom Lansford] “The reason I use flv is to create titles from AE for PPro and I use the alpha channel. FLV is the only output format from the media encoder that expressly presents the option to encode the alpha channel. So I do not care about FLV itself, just the right way to export titles. “
If you encode using ProRes 444 or DnXHD 444 you will encode an alpha channel as long as the source composition contains one.

[Tom Lansford] “BTW, I do not care about flv per se. I just want to do titling with an Alpha channel. I could use any output. It would seem to me to be a simple thing and at the moment, I am making the assumption that there is a way to do this using the standard means of output from Adobe CC, and that I just have not found it or recognized it yet!”
When you select the Output Module set it to RGB+Alpha, then select the format you want. Note: not all formats support Alpha.
