Photoshop Sequence Missing Frames

[Walter Soyka]

AE is normally quite good about working with image sequences. We’ll need a lot more information to help diagnose the problem.

How were the files made? Are the filenames perfectly consistent? Is there anything different about the frames it’s skipping? Any disk permission issues? Can you open the skipped frames in Photoshop?

Thanks for the response. I exported a photoshop sequence from after effects using the “make movie” rendering tool. I then opened all the files in photoshop, modified them, and then tried to import them as a photoshop sequence. I tried importing them as a composition and as footage with and without the “force alphabetical” option. It seems it be consistent in skipping every fourth frame when I import the files back in. The only work around I can think of is to import all the files and make the sequence myself.

Are you getting an error message on import, or does it seem to be missing frames visually? If the latter, how are you confirming it’s every fourth frame? Are you using the same frame rate throughout your project?

I don’t get any error on import. When I bring it back into project and drop it in the composition it’s visibly shorter than the in and out points I exported it from.

Then when I compare it to the footage it exported from (by comparing the frames of each layer, looking frame by frame) I notice that it starts to skip frames starting with the fourth frame, and then every 4th after that is skipped as well.

I have no problems when bringing in the photoshop files individually, and have been having this problem for a little while now. I normally don’t work with as many frames though, so I’ll just piece it together myself, but now it’s becoming quite a hassle.

All the frames are there in the folder. If I import them all and put them in a composition frame by frame they would match up to the right length without missing frames.

Are you sure it’s being interpreted at the proper frame rate? It would be shorter if it were a 23.976 fps image sequence being interpreted at 29.97 fps.

I didn’t even know there was preference for it. Changed the frame rate to 23.976 under Preferences>Import and it solved my problem. Thanks for the help.

Just for your reference, you can also use Interpret Footage to change the frame rate on an item without re-importing.
