i input my videos then edit the clips, when i select render the playback immediately becomes choppy then stops playing, jumps around. should i just wait to render till right before i export? what is rendering? shouldnt it make the playback smoother?
What operating system?
What version of premiere Elements?
What is your media file type, codec, and frame rate?
Does the media match the project settings?
What graphics card?
Is the graphics driver up to date?
There is no need to render before export.
