    h.264 choppy render/export

    stalbot207

      Hey everyone,

       

      So I'm trying to render out an edit that I made but I'm getting random choppy feedback.  The original footage is shot in 60p.  I have posted the first 5 shots on vimeo.  Shots 2, 4, and 5 are all set to 40% speed to bring them down to 24 fps.  Shots 2 and 4 work fine and the beginning of shot 5 is fine but then starts repeating each frame once. 

       

      Here is the rendered version so you can see what I mean.  Password is "otis".

      Here is the original 60fps shot of the shot that gets choppy.

      My render settings are basically just h.264 set to the Vimeo 720p setting.  Then I changed it to the 2.40:1 ratio.  And an even 24fps. 

       

      Please help me.  I've been stuck on this for a while and now I'm trying to reach out to new forums to get help.

       

      Thanks in advanced.

          What happens if you skip making it an even 24 frames per second?

           

          Is your footage really 60p or is it 59.94? I would think that rounding it off could be the problem. It is hard to say since I have never seen that symptom before. Vimeo doesn't have a 24p setting. Only 23.976 so maybe? It's worth a try.

            set to 40% speed to bring them down to 24 fps.

             

            Assuming a 24p sequence and export, don't do that.  Right click on the clips in the bin and choose Modify>Interpret Footage...

             

            From there change the frame rate to 23.976.

             

            Take note that you should be doing this for ALL clips shot at 60p.  Any clips you want to run at "normal speed" should be shot at 24p.
