Problem: getting black borders on YouTube 1080p

[cinedan]

I uploaded a 1080p video to YouTube and I'm getting a black border around the video. I first made a video file: WMV HD 1080 30p. I have other videos on YouTube in 720p that fill the frame fine. How can I fix this? Note: if you click on the link below, it only shows black bars on the top and bottom. When viewed ON the YouTube site, you see black bars on the sides as well. My YouTube screen name is: THXDTS.

Hi
I had similar problems when creating Flv files

Try disabling Non Square pixel Rendering before rendering the project to WMV

I fixed this problem by removing the title text with a blue background at the beginning. I would like to know how to keep the title and still have no black bars. Do I somehow copy the attributes of the video to the title?

Hi

As a work-round you could create the title, render the title to a video file.
Add the video file to the main project.

Dan, did you try the Non Square Pixel option, if yes I assume it did not work.
It would be nice to know, then I wouldn’t recommend it again.

Can you give some details of your original video files properties.

I think you need to start your video with a short (black) video clip in the timeline, and then insert your title

There is some more strange behavior on YT 1080p which I reported some time ago on the YT forum, but got no reply.... On http://www.youtube.com/watch?v=wS_11eCKx0o you can find a full HD electronic testpattern(AVCHD still video) which perfectly plays back with PowerDVD on my fullHD PC screen set for a 1:1 pixel map. When uploaded and played back via YT 1080p on the same display, the picture is schrinked (resized horizontally to about 1870 pix)), put on a 1080 canvas, which results in black borders left and right and aliasing visible in the 1920 bars. Vertically the image is not only resized resulting in a black bar under the image,. but contains only 540 lines (one field) resized and mapped on a vertical ~1050 pix canvas. So vertical resolution is at least being halved.

Trevor,

Disabling the non square pixel option did not work.

Here are the details of of my original video file (.m2ts)
File format: NTSC HDMV
Video Type: H.264 Video, upper field first
Attributes: 24bits, 1920x1680, 16:9
Frame rate: 29.970 frames/sec
Data rate: Variable bit rate (max 16000 kbps)
Audio type: Dolby digital audio
Attributes: 48000 Hz
Layer: none
Bit rate: 256 kbps

I will try the title work-around and let you know later how it turned out. Takes too much time to do quickly now.

Thanks!

Hi Dan

Thanks for the video info.
I happen to have a sample file using those settings

I had some problems with rendering producing borders.

Disabling Non Square pixel Rendering seems to work, but I had to disable both options.

1 / From Project Properties
2 / From the Create Video File window-Options

Removing the one option produced borders.
