I think you hit the nail Robert, I had a feeling that the interpolation =
of animated frames vs sequenced images could give some different result =
regarding to TimeRemapping.
But you was able to spell it out :)

Yes, proxies is also a nice solution. But they should be =ABpermanent=BB =
proxies. If AE change from proxies to the =ABreal=BB comp at render =
time, the problem would still occur.

Changing keys to hold frames does indeed do the trick!

Thanks!
