Elements 15 render issues

[Cgruber]

Hello,

I am having issues with elements 15 rendering. I meet all system requirements. Upon placing a clip on the timeline it does not prompt to render unless i do something to the clip such as add slow mo and even after that the clip still lags. any help is much appreciated........phone support is no help

Thanks

When the project settings and the footage match like they should, there is no need to render previews.  When you change things or add footage that does not match, preview rendering can/should help with smooth playback reviews.  Depending on the strength of the computer and the complexity of the source video, smooth preview playing may not always be perfect.
