    Output file is different than timeline

    fmrees

      Hello everyone,

       

      This is my first post here, hope you can help me out with an issue I'm having on Premiere Elements 8.

      What happens is the following:

       

      I'm creating a video with a mix of movie files and still images. The format is a 16:9 Widescreen. As some files do not fit the size, I have unchecked Scale to Frame Size, and I have streched them out a bit. It doesn't look 100%, but it works fine for what I need. So, I have filled the whole black space in the timeline there with the videos and still images. I have added some pan and zooms in the still images, so it doesn't look so boring.

       

      Now, when I export the video, I'm doing these settings: WMV format HD 720p 30 fps 1.0 Square Pixels.

       

      Most of the video (98% I would say) exports perfectly. There are only 3 still images which aren't positioned as they were supposed to be. They are all too much to the right side of the screen, therefore showing the black edge on the left and cutting the right side of the image off-screen. All other still images and video files are positioned exactly as I see creating the video. I have done some tests, like 1.21 Pixels, but then it messed up the whole thing, all out of place.

       

      One problem is that it takes me about 1 hour to export in this WMV format HD 720p 30 fps, so for testing stuff it takes hours.

       

      Anyway... any clue of what could be wrong for those images to be wrong in the output file?

       

      I could also try another format, but this is the only one I could find which the quality was fairly good in the output file (size about 170mb). It's for a YouTube video, so I'm looking for a decent quality for a video there, about 5 minutes long, HQ.

       

      Well, I say beforehand than I'm a noob with video editing in general and Premiere Elements specifically. So, a little help would be extremelly important.

       

      Thanks a lot for reading my challenge here.

          First, ensure that your project settings match your source files. This is very important. You set these project settings when you start a new project.

           

          Also, ensure that your photos are no larger than 1000x750 pixels. Oversized photos have a tendency to misbehave in a number of ways -- and could actually be a reason your renders are taking so long.

           

          YouTube can be a challenge to create a high quality image for. Even if you post great video, they re-encode and recompress it until it looks like crap. But, for the best quality possible, use the settings listed in the FAQs to the right of this forum.

          Without knowing more about your computer specs or even what type of camcorder your video came from, it's hard to be more specific. But those things usually resolve the majority of problems.

            To follow up on Steve's comments on resizing the stills, prior to Import, if one uses Photoshop/PSElements, the quality will be better, and the processing time cut to the minimum.

             

            You mention having to "stretch" some of your images, and this would then force PrE to Scale those images. The Scaling algorithms in PrE are just adequate, while the ones in PS/PSE are much better. They are, after all, image manipulation programs.

             

            Given that most of your Project is working fine, I would go to those 3-4 problem images and Delete them, leaving the gap for a moment. Go to your original images and in PS/PSE (or other image editing program) Scale those to just what you need. I match the Frame Size of my Project Panel, unless I need to Pan on a Zoomed out image, and then I calculate the exact size that I need. The 1000 x 750 size (for an SD Project) is a good rule-of-thumb, as it gets one very close, but still allows some pixels to move around.

             

            Once you have chosen the size and Scaled in the image editing program, Import those 3-4 images into your Project, and place them in the gaps.

             

            This ARTICLE will give you some more tips, plus tell you how to use automation to Scale a folder of images with just a few clicks. It was written for Photoshop, but PSElements has most of these capabilities, but they are accessed slightly differently. These tips might be very useful on your next Project, when working with still images.

             

            Good luck, and happy editing,

              Hello and thanks for the answer.

               

              Indeed, I was using 3000x3000 pixels still images because I thought it would have a better quality. Now I reduced the size, and it's rendering the video at this moment. We'll see how it turns out.

               

               

              When you say "project settings match your source files", how does it work with the still images?

                First - good luck with the burn!

                 

                Normally, one will take the specs. of their Video files and choose a Project Preset, that matches that 100%. In the case of a still image only SlideShow, one rather works backward. Here, the output specs. will determine what one needs. Let's say that the output will be SD DVD-Video Widescreen. They would choose either an NTSC, or PAL, DV Widescreen Project, and then Scale their stills to match.

                 

                If one is going to BD, then there are some choices. This FAQ Entry lists the possible formats. If one is going to deliver in another format, then the specs. of that format will define the Project Preset. Note: PrE only has so many Project Presets, and does NOT allow for Custom Presets to be created, so some allowances might have to be made. Choose the Project Preset that comes as close, as is possible, and then Scale the stills to match that. I would always choose a larger Frame Size for a Preset, than a smaller one. Here, bigger IS better, as Exporting to a smaller Frame Size will look better, than Exporting to a larger one. Still, getting close is the best way to go. Even Exporting from HD to SD can show some degradation.

                 

                If you need to go to an iPhone output, I would choose a larger format from the Project Presets provided, and then Export/Share to the iPhone format, with a usable CODEC.

                 

                As for the quality of large stills, unlike when going to print, the Video can only show a certain number of pixels at a time - the Frame Size. All of the excess pixels are either thrown away, or if one is Scaling to Frame, manipulated. At the most, one ONLY needs extra pixels if they are being animated with a Pan on a Zoomed out image. Then, those "extra pixels" will come into play, as the image is basically moved below the aperture of the Frame Size. To keep PrE from having to manipulate my stills, and to keep the system overhead to a minimum, I'll do the math for any image, that I know I will Pan on, while Zoomed out. The 1000 x 750 kind of splits the difference, but keeping the size down, but still allowing some movement - kind of a "best of both worlds." It also keeps the math out of things and makes it simple.

                 

                With Scaling, manipulation of the pixels will take place somewhere. PS offers several possible algorithms for this manipulation, while PrE does not. It does an OK job, but PS does a much better job, and offers more options, like Bicubic Sharper, and Bicubic Smoother. With PrE, it's a one-size-fits-all. Also, PrE is far less efficient at applying these Scaling algorithms, than the image editing programs, like PS. So, when dealing with large still images, it's a win-win using an image editor to Scale - quality will be better and efficiency will be better.

                 

                Good luck, and hope that this helps,

                  AHA - good news!

                   

                  After resizing these 3 still images down to about 1000x1000 pixels the exporting issues with 2 of them are gone. Now only one is still with the same problem, but in a lesser degree.

                   

                  I'll resize it down to about 900x800 and see what happens.

                   

                  Thanks. I'll post again as soon as I have some news.

                      Great, it worked fine now. No more weird behavior with the still images. I resized them in Photoshop Elements, and imported again into Premiere Elements. All beautiful and file size is smaller in the end.

                       

                      NOW... may I use this same thread for another novice question?

                       

                      When I'm starting a project, I'm choosing the following configuration:

                       

                      NTSC DV Widescreen

                       

                      Would I get a better result if using NTSC HDV 720p 30?

                       

                      Because at the end, I'm exporting my movie as Windows Media (.WMV) HD 720p 30.

                       

                      Thanks!

                        If you have 100% still images, and no Video assets, then I would bend the cardinal rule - match your Project Preset to your Assets. Since you have total control over your Assets (remember - no Video here), I'd go with the Project Preset that matches your Export/Share settings, and then Scale your still images to match that.

                         

                        Add Video, and I'd go back to matching THAT with your Project Preset.

                         

                        Good luck,
