    MP4 playback extremely fast?


      Hi, I'm using an older version of APE and seem to remember being able to use MP4s without an issue. I've come back to the software recently to put out some content on Youtube related to gaming. I use the OBS recording software and it seems to work fine, and I in fact already posted 2 unedited videos. I'd like to edit my future ones now but am being hampered by a problem regarding MP4's as best as I can tell. They playback at extreme speeds and timewarping them doesn't seem to help either. 3 minute video turned into a 5 second frame mess. I tried to convert it with the most reliable converter I own, but it botched the audio. What can I do?

          What version of Premiere Elements and on what computer operating system is it running?


          What is your project preset?


          What are the properties of this .mp4 video

          Video compression

          Audio compression

          Frame Size

          Frame Rate

          Interlaced or Progressive

          Pixel Aspect Ratio


          You say you have a 3 minute video turned into a 5 second frame mess in Premiere Elements. What are you getting - the whole video in fast motion or only a 5 second portion of the whole 3 minute video?


          Is your video being recorded with OBS using a variable instead of constant frame rate?


          We need to get a handle on your source media. MP4 is only the file extension (wrapper format) for the file.

          Please put together the requested information and then we will plan the troubleshooting strategy.


          Thank you.

            Premiere Elements 9, I believe. Windows 7 Home Edition


            I tried both NTSC 720p and HDV 720p

            Not sure how to look at

              There is a problem with your details in post 2.


              If your video is 720p and has frame rate of 25 frames per second, you do not have interlaced video. What you would have would be

              1280 x 720 @ 25 progressive frames per second.


              Since there is no




              DSLR 720p25


              my choice for project preset would be



              HDV 720p25.


              Drag your clip into the Timeline of the project set for HDV 720p25.


              With the Organizer header active, go to the Project Tab in the row below and click on it to reveal your file in the Project media view.

              Right click the thumbnail for the file there, select Interpret Footage...


              What does it show in the Frame Rate section for

              Use Frame Rate from File: _____


              Assume this frame rate _______?


              Whatever the case, dot the option Assume this frame rate and type in 25 (if that is the frame rate of your file).. And, then close out of there. I will explain later. There is a glitch in 9 regarding the Interpret Footage frame rate which may or may not apply to your situation. But, it needs to be explored.


              Is the situation corrected or changed in any way?


              Is there any possibility that the video that you have was recorded with motion option in a camera before the file was imported into Premiere Elements project?
