    Can't render preview on some clips


      In my timeline I've got a bunch of clips - some have yellow lines above them in the render bar, some red, some green.  And then some have no lines at all, it's these that are the problem.


      When I tell it to 'render preview' it will make all the clips with yellow and red lines turn to green just fine, but does nothhing with the clips that have no lines above them at all, it's like it thinks 'these clips are so easy to play I dont need to render preview, they dont have effects or anything on them', however it is sorely mistaken because when I play back the preview everything plays fine except those clips, which stutter and skip (because they are uncompressed HD video).


      Is there a way to force every clip to 'render preview', not just the ones Premiere thinks need it?

          You cannot render them for preview as they already run native.

          You do can lower the playback resolution in both monitors as your machine can probably not handle the uncompressed files.

          You will find the settings under the rgb coloured button.

            Unfortunately that didnt help, I set it down to 1/4th size (lowest it would go) and it still was stuttering during those clips.


            Best answer I can think of is to make an effect with .001 opacity across the whole project to juke adobe into thinking all clips need preview rendering.  This offends me as a human being, hopefully someone has a better solution.

              Welcome to the forum.


              Can you give us the full specs. of your computer, and especially the GPU (make model), plus the installed video driver? The more detail, the better.


              Good luck,

                  Footage type and source?

                    Footage is 720p, 60fps, recorded HDMI input on a capture card, stored in a JPEG codec of some kind (not sure how to find the exact name of the codec)

                      Use MediaInfo. Post a report on one of the files using the Text View mode.


                      I suspect you are trying to edit these off a single drive (maybe your system drive), and it's just not fast enough to maintain smooth playback.

                        I am editing it off a seperate hard drive, an external harddrive connected via USB.  So that could very well cause it.

                        I'd like to keep editing it there though, if there's some way I could tell premiere to cache the files even though they look like an agreeable format...
