  • Sony Vegas Pro 9 – Rendering sped up .mts files

    Posted by Sander Somma on October 21, 2012 at 12:34 pm

    Hello, Im having a heavy problem with rendering sped up + velocity files in Sony Vegas Pro 9.

    I tought the problem is in field order. As
    scan type – interlaced
    scan order – Top field first
    on the original files. When I sped them up and rendered with none progressive, or any other way, they are with the worst quality.

    Then I rendered not sped up original files to None progressive.
    Then sped them up and rendered again, and theyre still horrid.

    Im out of ideas and I dont know what to do…

    My camera is Canon Legria HF M36 HD. Originals are .mts files.

    It sounds like you’re having interlace problems. Please post a screen shot of your Project Video Properties and your Render Video Properties so we can see if something isn’t set correctly.

    The preview looks good, but the rendered file looks really bad. Scenes with no motion look great, but scenes with anykind of camera movement look really pixelated and bad. Obviously interlacing but, now I have no idea how to fix this.

    Also after I rendered the original to progressive

    In media info it does show
    Scan type :Progressive
    but
    Scan order :Bottom field first
    and
    Compression mode: Lossy

    Perhaps that helps..

    There are a couple of things going on here.

    (1) Your camera shoots PAL HD 25p but your project is set up for NTSC SD 29.97 interlaced. I assume you are in a PAL country so it’s important for you to know that you never want to use NTSC for anything. Not for your project or for your rendering.

    Change your project to use the HD 1080-50i (1920×1080, 25.000 fps) template. If your source files are really 25p, then also change the project Field Order to None (Progressive). If you are shooting interlaced footage with your camera then leave the Filed Order alone.

    (2) You are rendering to a 24p HDV template that has been modified to use 25fps but I’m not sure you want HDV. More than likely you want to change the Output type to MPEG-2 but start with changing the project to be correct first.

    BTW, what format are your recorded video files? Did you record 25p or 50i. Does the Vegas media properties for these files agree with what you believe them to be?

    I did all of that, changed Project and changed to MPEG-2
    Results are still the same, any movement in the video after being rendered is with really bad quality.

    Here’s a snap of mediainfo on the original clip. Perhaps this could help you further. And thank you for trying to help me, Im sure it’s a small thing that im overlooking, hopefully.

    From that screen shot your project properties should use the HD 1080-50i (1920×1080, 25.000 fps) template with no other changes because your footage is interlaced.

    Now what does Vegas Pro think the footage is when dropped on the timeline?

    Right-click on an event on the timeline from that media file. Go to Properties | Media tab and grab a screen shot of that and post it here.

    Here’s the snap.

    OK, so we’ve determined that you are shooting 1080-50i interlaced and Vegas is interpreting the footage as interlaced therefore your project should definitely be set to 1080-50i as previously suggested.

    What could be happening is that the motion in your video is too fast for the Blend Fields method to work. In your project properties, change your Deinterlace Method to be Interpolate Fields and see if that clears things up.
