    Slow RAM preview playback

    Marc Lucas Level 1

      All Comps in a project were 720p 25 fps There was one clip a piece of stock footage that was 24p so I retimed it because when I conformed it to 25p it was shorter in the timeline. I exported and reimported into the project. Now all the original footage (talent speaking to camera) is playing back really slowly like its being really slowed down?

       

      I have seen that the RAM preview is down to 15 fps

          1. How did you change the 24p footage to 25? If there was no audio or audio was not a factor the right way to do it is by changing the footage interpretation. There would be no effect on renderings that way.

           

          2. How are  you doing a RAM preview?

           

          3. What are your system settings, OS, and AE version? What about your composition settings? There's not much to go on here.

            OSX 10.9.1

            AE CC 12.2.0.52

             

            The footage was 24p I then interpreted the footage as 25p this mage the footage shorter so I then used Time/Retime footage to lengthen the footage by a couple of seconds. I then exported this and imported back into the project. Yes as you mentioned I could of just conformed but only realised that after. Then after reimporting the footage back into the project I replaced it with the 25p footage. I am RAM previewing by just clicking the RAM Preview button in the Preview player. Now only playing back at 15 fps even if I have opened a new project. I have also noticed that the audio default export settings had changed to 8kHz instead of my default 48

              For test purpose, try creating a new project, importing only one of your footage, and check if the RAM preview is 25fps in there.

                I did that I created a new project and only imported one of my green screen shots that was shot at 25p and RAM previewed and it played back slow so I think it is AE in general not just the project?

                  That is a bug in 12.2. Adobe is aware of it, there is a workaround, and a fix is on the way. See here.

                    Thanks for the heads up with the Audio bug:-)

                     

                    AE is really killing me today with the other RAM preview problem, I have TV commercial on a deadline really annoyed.
