Thread: Problem with aspect ratio

  1. #1

    Default Problem with aspect ratio

    Hi, I have a LED LG TV 47inch LW95000.I use the latest version of mezzmo 2.7.1. I like when I play a video with aspect ratio 4.3 on TV it's only stretched from left and right and fills the screen. I try from TV but it have only two options real size and full screen but in full screen state I have black bars on the left and right, so I try other device profiles such as generic device ETC but I couldn't do that.So when I play a video with resolution 720*576 and aspect ratio 16.9 on TV it's played with aspect ratio 4.3 that its wrong aspect ratio. please help me.
    Thank you.

    Please post the FFmpeg information on the video you are streaming. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'.

    One thing to try is to pre-transcode the file to another format. Right-click on the file in Mezzmo and click 'Pre-transcode Files'. Select your device and click Choose Formats. Select a format and click OK. Click OK to start pre-transcoding. After the file has completed transcoding (go to the Transcoding pane to see this), try streaming the file again.

    Hi, I tried transcoding but it wasn't successful and the video was played with aspect ratio 4.3 whereas the real aspect ratio was 16.9.
    I have this problem with mpg and TS formats with resolution 720*576 and aspect ratio 16.9. when I change resolution to 720*400 with converter software it's played true with aspect ratio 16.9.

    These files are being streamed directly to your LG TV without any changes or transcoding, so it seems your TV's firmware is getting confused by the mix of MPEG-2 format, the dimensions and the aspect ratio.

    You seem to be recording these videos from a TV broadcast. Can you adjust the recording settings for the tuner card/hardware/software that you are using to record with?

    Also, try pre-transcoding again. Make sure you are using the LG TV device profile (check the Media Devices dialog in Mezzmo). Right-click on the video in Mezzmo and click 'Pre-transcode Files'. In the Pre-transcode Files dialog, choose your device and then choose mpegts, h264, ac-3 as the transcoding format. Also check the 'Force full transcode' checkbox. Click OK to start transcoding. Once transcoding has completed, try streaming the file again.

    I tried receiver settings but it wasn't successful, so tried pre-transcoding again as you said but it wasn't successful. I used "LG TV" device profile.
    FFmpeg information below got after transcoding.

    Please send us one of your videos that has the aspect ratio problem and we'll try it here with our LG TV. If the video file is larger than 10MB, then please upload it to a filesharing site like dropbox, mega or rapidshare and then email us the download link to support [at] conceiva [dot] com.

    Hi Saeed,

    Thanks for this information. As mentioned, we tested playing the sample video you sent us on many different devices, but it does not play correctly in the majority of them (LG, Sony, Samsung, Panasonic). We can get it working by using the stretching mode on these devices to fix the broken aspect ratio, but your LG TV does not have this stretching mode (it only has full and original modes).

    Remember that Mezzmo is just streaming the video file directly to your TV. Mezzmo is not altering it in anyway. So the broken aspect ratio has nothing to do with Mezzmo - it is just how your device renders this video.

    If you cannot change (improve) the aspect ratio or dimension settings in your recording hardware/software, then you are left with no choice but to convert (i.e. correct) the videos after recording them.
