    Loss of image quality after rendering

    Jo.hose Level 1

      Premier Elements 12

       

      I have captured a sequence from Google Earth as an .MP4 that I want to include in a movie. After adding it to a new project (PAL AVCHD 1080p 50fps) the resolution of the image is excellent until I render the clip, when the image becomes somewhat blurred - particularly noticible in the place names. Why does PE do this and is there a way I can retain the original image quality?

          On what computer operating system is your Premiere Elements 12 running?

           

          What is the project preset that you or the project has set?

          Please see Edit Menu/Project Settings/General and the readings for Editing Mode, Timebase, Frame Size, and

          Pixel Aspect Ratio (even if they look grayed out)?

           

          Please verify PAL AVCHD 1080p 50fps - is that the description of the source file?

           

          Let us start here and then decide what next.

           

          Thank you.

            Hi ATR

             

            Nice to be talking to you again.

             

            Computer o/s = Windows 7

             

            Project settings: 50.00fps, 1920x1080, Square Pixels (1.0)

             

            PAL AVCHD 1080p 50fps is the project setting.

             

            I don't know what the source file format is: just whatever the GoogleEarth

            default capture format is. I'll try to find out.

             

            Just to be clear, the clip looks fine when I put it into the timeline,

            though it runs jerkily. It's when I then render it that the loss of

            definiton occurs.

             

            Thanks

              The source file details (from Windows Explorer Properties) are:

               

              Frame width 1920

              Frame height 1080

              Data rate 4936kbps

              Total bitrate 5066kbps

              Frame rate ...Various - the default capture rate seems to be 16pfs and I've

              tried slowing that down to 10. Doesn't make any difference to the fault I'm

              reporting

                Thanks for the information. Appreciated.

                 

                I was doing some research into Google Earth and found it following document

                Steps for recording movies - Earth Help

                 

                Please double check the project preset setting within the project

                Edit Menu/Project Settings/General....if the project preset is established as PAL AVCHD AVCHD 1080p50, then

                you should see under General

                PAL.JPG

                 

                I am focusing in on frame rate. What was the actual frame rate for the video that you imported into

                the Premiere Elements project....even though you looked at 10 frames per second, did you finally

                go with 50 frames per second?

                 

                I got the impression that the recording settings were either .wmv, .mov, and .avi. Where did you get

                the .mp4 file extension? Do you have a Pro version of the software which offers that option? By the

                way, I am assuming that you have the latest version of QuickTime installed on your computer with

                Premiere Elements. Have we discussed that previously?

                 

                How are you planning on exporting your Timeline content from this project? It might be a good idea

                to do a mini test run export. This might point us to a preview not export issue or to an issue involving more

                than just the preview.

                Please review the above so that we can plan troubleshooting strategy.

                  Dear ATR

                   

                  Once again you have come up trumps!

                   

                  Before doing anything else I followed your suggestion and did a trial

                  export. - the exported file looks excellent so it was a preview issue only.

                   

                  Thanks again

                    Thanks for the great news of the export success. Great job in sorting out preview from export issues. I took a look at Google Earth.

                    Looks interesting and potential for giving some stunning results.

                     

                    I do not recall if we discussed this before, but you might try the following to determine if you can

                    improve the quality of the rendered Timeline content....

                     

                    a. Right click the Edit area monitor, selecting Playback Quality, followed by Highest instead of Automatic

                    and/or

                    b. Set the preference for Timeline Render Quality to the High Quality choice if it is not set at that already.

                     

                    Best wishes

                      In case you are interested I used a third party freeware utility to capture

                      the screen output from GoogleEarth. It is called 'Screen Capture Recorder

                      v.0.12.8' and is available from

                      http://sourceforge.net/projects/screencapturer/files/. I have found it very

                      customisable and easy to use.

                       

                      Regards

                        Thanks for the further details of your workflow.

                         

                        It sounds very interesting. I will give it a look and report back with

                        my results at a later time.
