  • 704×480 pixel aspect ratio is odd

    Posted by Deborah Curtis on August 21, 2008 at 4:02 pm

    Hello everyone,

    This is my first post on this Forum.

    I am running Sony Vegas Pro 8.0. I have a Panasonic SDR H-18 HDD camera that produces an MPEG-2 file that I’m importing into Vegas. I have my camera set on 16×9 widescreen format and the XP setting. XP is supposedly the highest quality file. I can’t find squat about the exact file specifications that are created for hte MPEG file though. (It’s frustrating!)

    My problem is that when I choose the custom button, and have Vegas set the properties for the MPEG file, it sets the Pixel aspect ratio to 0.9091 (NTSC DV) which makes the picture seem distorted.

    If I change this to 1.2121 (NTSC DV WIdescreen) it looks correct- but I’m still not sure the video is as CLEAR as it should be.

    Can anyone give me some suggestions?

    The field order is at Upper field first:
    Frame rate: 29.970

    I’ve got the Motion Blur at Gaussian and have been messing with the pixel format a bit to see if it makes any difference.

    Thanks!!

    If you are importing and working with 16×9 widescreen footage,
    First thing you do in vegas is to select one of the default widescreen project setting that fits what your camera captures.
    (no need to mess with any of the setting).
    Then start your edits from there.

    I started that way- using the default Widescreen setting…

    The default widescreen settings are 720 x 480 and I felt this may be distorting the picture more since in reality the pixels are only 704 x 480.

    So that’s when I thought I’d try letting Vegas set the file properties by using the custom button- and it did change the file settings from 720 to 704.

    I guess I’m just confused why the custom button didn’t choose the widescreen ratio.

    I understand.
    Because your footage is 704X480 you need to make a custom change.
    704×480 is not a standard resolution….so you wouldn’t find a
    default setting for it. Here is a link from some other similar users:

    That was an interesting thread on Premiere Elements… It looks as though they are importing the file at 704 x 480 and then they EXPORT it at a different format of 720×480 16×9

    If I had to do it all over again, I most likely would never have purchased the video camera I did. It has been a disastrous nightmare trying to get software to be compatible with the MPEG file structure. I tried Premiere Elements and it crashed consistently when rendering the MPEG files. I hated it.

    Sony Vegas has actually been quite good to work with, if I could get the quality of the video where I want it. I can copy the video straight from the camera to a DVD, and it is better than when I import it into Vegas and then burn it. I suppose I should expect some loss, so I’ll just have to learn to deal with it.

    I’m going to continue to mess with the settings. I’ll post back what I find works best for other poor souls who have this issue in the future 🙂

    I have found that the way to get the best picture with the MPEG was to:

    1. On the MPEG File properties choose the custom button, and have Vegas set the properties for the MPEG file. It will most likely set the Pixel aspect ratio to 0.9091 (NTSC DV) — change this to 1.2121 (NTSC DV WIdescreen). Keep the Width at 704 Height 480.

    2. I changed the Pixel format before rendering to 32-bit floating. It takes a lot longer, but it was worth it if I got a bit mroe quality.

    3. When you import each individual MPEG into the timeline, you also have to set the pixel aspect ratio. Right click on the clip, select Properties. Then go to the Media tab and change the Pixel aspect ratio fo 1.2121. Also change the field order to Upper Field first if this is how the MPEG file was imported on option 1.

    4. Rendering- Render as a MainConcept MPEG-2

    I chose the Template for DVD NTSC Widescreen compatible with DVD Architect- and then MODIFY it.

    Project Tab: Best
    Video Tab: Make sure the Width is 704 and height is 480. The Aspect ratio should be 16:9 display. Profile and Level are Main. The field order should be Upper field first. Set the video quality to 31. I used a Variable Bit Rate maximum ob 9,500,000 Average 6,000,000 Min 192,000
    Advanced Video – no changes
    Audio – MUST select Include audio stream unless you want to render audio on a separate stream. If you don’t check this you won’t have any audio.
    System- I didn’t change anything.

    Good luck! I burned with TMPGEnc Tsunami-MPEG and had great results.
