    Exported video too large, quality poor

    clanderson00 Level 1

      Hey guys. I'm starting with a 1440x1080 mts video, trimming it down (total trimmed length is about 7 minutes) and exporting it to a 1440x1080 mp4.

      But sadly, I have to increase the bitrate very high in order to get quality that approaches the original, resulting in a much larger file size. I managed to get the size of the exported video (shown in the table below) to a reasonable size, but it was still lower quality than the original.. Can I get some help here? Essentially, I just want to export the video with the original resolution and around the same size but in something like .mp4 format.

       

      PowerDirector11 achieved this with no fuss.

          What version of the program are you using? What your project settings (listed under the Edit menu)?

           

          What model of camcorder is your original video coming from?

           

          What do you plan to do with the video that you're exporting? Put it on a BluRay disc? Post it to YouTube? There are optimized mp4/avc settings for every use.

            The answers are in the details. But, from what you offered above, whether you have Premiere Elements 10 or 11 Windows, here is what I am suggesting that you try.

             

            Import your 1440 x 1080 HD anamorphic 16:9 @ 29.97 interlaced frames per second into Premiere Elements, using the project preset of:

            NTSC AVCHD HD1080i30.

            If you are using version 10, you do that in the new project dialog yourself.

            If you are using version 11, the program is supposed to do that setting automatically based on your first drag of the clip to the Timeline. Check Edit Menu/Projects Settings to make sure that the program has recognized your video properties correctly and assigned the appropriate project preset. If not, open a new project and go to File Menu/New/Project and set the project preset yourself, making sure to put a check mark next to Force Selected Project Settings on This Project. After OK'ing out of there, then bring in your video via Add Media/Project Assets/drag to Timeline.

             

            When you get around to exporting, give the following a try (in looks like that was the area that you were exploring already)

            If version 10, Share/Computer/AVCHD

            If version 11, Publish+Share/Computer/AVCHD

            use the preset = MP4-H264 1920 x 1080p30

            That preset uses default bitrates of Target 32 Mbps and Maximum 40 Mbps. Go with that to get a baseline for your video which appears to have an overall bitrate of about 12 or lower Mbps. If necessary, redo, Lowering for file size requirements.

             

            Then let us know what that looks like.

             

            Can you shoot at 1920 x 1080 at a higher bitrate with your camera? And does your camera shoot progressive as well as interlaced video?

             

            Thanks.

              Version 11

               

              Output:

              Project Settings (Only one of many settings tried): NTSC, 1440x1080, 29.97 fps, De-interlaced

              AAC, 256 kbps, 48 kHz, Stereo

              VBR, 2 Pass, Target 12.00, Max 17.00 Mbps

               

              Source:

              Clip, Sequence 02

              1440x1080 (1.3333), 29.97 fps, Upper, 00;07;13;00

              48000 Hz, Stereo

               

               

              Coming from a Canon HD Video Camcorder (not sure exactly what kind, but it's relatively new)

              As far as what I'm planning to do with it, there are multiple avenues this video takes after I get done exporting it.

              The main one is burning to a DVD though - which Premiere Elements 11 has thoroughly proven to me it can't do well. (The response from PE11 support was along the lines of "this is a video editing program, not a DVD burning program", basically "tough luck").

              After that, it gets uploaded to Youtube, which is why I need the smallest size possible. (300MB source to a shorter but much larger 700MB output with comparable quality is unacceptable)

                With regard to YouTube...look at the export of your Premiere Elements 11 Windows Timeline to:

                Publish+Share

                Computer

                AVCHD

                with the preset

                YouTube Widescreen HD

                under the Advanced Button/Video Tab

                set for

                NTSC

                Profile = High

                Level = 5.1

                Frame Size = 1920 x 1080

                Frame Rate = 29.97 frames per second

                Pixel Aspect Ratio = Square Pixels

                Field Order = None (Progressive)

                Leave everything else as is until you get a baseline look at the results. Then you can explore changing export bitrate settings.

                This file can be uploaded to YouTube at the YouTube web site which can offer larger file size and longer duration.

                 

                For DVD-VIDEO

                Right click the video on the Timeline, select Field Options and Reverse Field Dominance, and then try the burn to disc with the preset for NTSC widescreen. Before the burn to, check out the burn dialog Quality Area for Space Required and Bitrate. If you are using a DVD-R disc (4.7 GB/120 min), remember that 4.7 is really 4.38 GB and the "for best results" recommendation is typically not to exceed 90 minutes on that type of disc.

                 

                We will be watching for your results.

                 

                Thanks.

                  Sorry, I don't need anything specifically for youtube or anything for burning a DVD, I would just like to export my project to a common video format such as .mp4.

                  Also, this is a 1440*1080 video, not 1920*1080.

                   

                   

                  One other question.. Why when I export it using the settings I gave does it give me this information?

                  Width                                    : 1 440 pixels
                  Height                                   : 1 080 pixels
                  Display aspect ratio                     : 4:3
                  Original display aspect ratio            : 16:9
                  

                  When I go to play it in some media players, it is displayed in a 4:3 aspect ratio instead of the proper 16:9. This doesn't happen with the original footage.

                    I realize

                    Also, this is a 1440*1080 video, not 1920*1080.

                    But on the export side of things many opt to use 1920 x 1080 16:9 square pixels since it does depend on a 16:9 flag that needs to be recognized by the player.

                     

                    In the case of 1440 x 1080 HD anamorphic 16:9, that 16:9 flag stretches the 1440 x 1080 to 1920 x 1080 for display after encoding.

                     

                    We will be watching for your results.

                     

                    Thanks for asking for clarification.

                      Oooooh I see, thank you for expounding on that! Makes sense - and also may be the reason why the video is displayed in 4:3 on my media players. Hah.

                        That "it does depend" should be "it does not depend"

                          Hahaha yes I think we did, I was editing one of mine and it booted me out as well.

                           

                          But I think you've done it! I have found a good balance between size and bitrate, and that 1920*1080 Square Pixel deal worked beautifully.

                          Thank you so much, I really do appreciate it!
