As the title suggests, when using the dynamic link in premiere pro to play with some graphics in Ae for a dng sequence, it only shows one single image instead of the whole sequence. It shows me the window for correcting the picture as it is a png file, but after clicking ok, it only shows one frame instead of the sequence.
If in Premiere Pro you imported the sequence as "image sequence" and then launched it into After Effects you shouldn't have any issues. After Effects also receives it as an "image sequence" and returns a composition with that image sequence to Premiere Pro. Make sure that when importing into Premiere Pro, in the import window you have activated the "image sequence" checkbox that appears when you click the Options button at the bottom of the window.
