If you have not already, please update your Premiere Elements 12 to the 12.1 update using an opened project's Help Menu/Update.
As for your import of the 1080p50, I suspect that you cannot do the Timeline rendering because it does not need to be rendered to get the best
possible preview as indicated by a no color of the line above the Timeline content....do you see no colored line there or orange line?
When you click the Render button above the Timeline, do you get play back of the video in the Edit area monitor instead of your Timeline rendering?
Also, are the gray tabs of the Work Area Bar set to span the Timeline content that you want to render?
Rendering the Timeline is for preview purposes only. The no colored line or the green line is the program telling you that you
have the best possible preview and that no rendering is needed or available. The orange line is the program telling you that
you need to render that content to get the best possible preview for what you are seeing and hearing in the Edit area monitor.
As for the export part of your question, I suspect that you need to think some more about the correct export settings -
If you have 1080p50 project, then you might want to consider an AVCHD.mp4 export. Please see
with Presets = MP4 H.264 1920 x 1080p25 if you are working in a PAL setup. Then you go to that preset's Advanced Button/Video
Tab and customize that preset to get MP4 H.264 1920 x 1080p50. Looking under Advanced Button/Video Tab export settings, it would
look something like

ATR many many thanks for your most helpful response.
Before answering your queries and prior to receiving you valuable advice I managed to successfully publish the video by using HD 720 50.mp4
Mu current version of Premier Elements is 12 and thank you I will update to 12.1
On the time line some of my clips had an orange line above - others none and there were no green lines - I am much obliged to you for enlightening me. - I thpught I should be seeing a green line - also on my first video after clicking on the Render - I could see 'X' number of clips etc were being rendered - on the current video 'nothing'
Yet again many thanks for educating me on the export of the video - noted everything you have to say and will do exactly as you suggest.
All I can say - is thank you and thank you and thank you again
Thanks you for the follow up. Great news that all is progressing with your workflow.
Another just in case mention....the short version
The no colored line typically appears for the first video dragged to the Timeline when there is a match between the project settings
and the properties of the video. It is the program telling you that you have the best possible preview (so no Timeline rendering needed or
available). But, once you edit that particular video, an orange line will appear over that content. Program is telling you that you no longer
have the best possible preview that will reflect the edit. So, you Timeline render that video, and the orange line turns green (a best possible preview indicator).
After that, the same routine follows when you edit that video clip that has been previously Timeline rendered. But, the indicator changes only from orange to green or green to orange. You will not see the no color line again for that clip. Its best possible preview indicator is no longer the no colored line but is now using a green line to indicate best possible preview.
As the saying goes it never rains but pours.
I have just updated my Apple system from OS X Yosemite Version 10.10.1 to 10.10.2
Have noticed a complete slow down on my computer but more importsantly I can't get the play head to move !!
Did you try the deletion of the Adobe Premiere Elements Prefs file?
I believe the Mac route is
Users\Owner\Libraries\Application Support\Adobe\Premiere Elements\12.0
Have you attempted to optimize your computer with a program such a free ccleaner run through?
Did you go through a recent check of the video card/graphics card driver version to assure that it is up to
date according to the web site of the manufacturer of the card. Does you computer use one or two cards?
Have we discussed
....the video format versa jpeg playback when the Timeline Indicator is not moving
...does the problem exist with and without the antivirus and firewall(s) disabled
...are you using a pen and tablet devcie instead of a mouse
Please review and consider and then we will decide what next based on your reply.
