IN your render queue, change your output module to TIFF Sequence with Alpha (you can setup a custom TIFF sequence if you want, but this will work).
This will export individual loss less TIFF frames to your specified directory.
Import the TIFF files back into the project and make sure you select all of them and make sure TIF sequence is selected. This will create a sequence in your project folder.
Right (ctrl) click the new sequence and select interpret footage and make sure your FPS is set to your initial frame rate. Create a new comp by dragging that sequence to the ‘make new comp’ button and export it like you would any other sequence.
Since the frames are already rendered, it doesn’t have to compute the effects while it renders.
Should work.
