Exported video too large, quality poor

May 24, 2013 5:17 PM

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.

    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.

    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.

    I think that we just had a collision in cyberspace. I was just putting finishing touches and corrections on that last reply when the system kicked me out. Nonetheless I think you got the core of the message, but for the record I left out a "not"

     

    Please refer to

    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.

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