Distortion in Uploading to Youtube

Hi,
I have successfully uploaded two video files to youtube. Here's the problem: post-upload the first one looks OK, the second looks TERRIBLE. Both of them looked decent pre-upload.\

The first clip was posted in MP4. Fine.

I've uploaded the second clip four times--in MP4, in MP4 after reprocessing to increase sharpness, in MPEG2, and in MPEG2 after reprocessing for increased sharpness. The MPEG2 clips came out slightly better looking, but both of the original, non-sharpness-boosted clips were so blurry that they were painful to watch, while both of the increased sharpness clips were FAR more distorted, almost indecipherable.

Of course, youtube's video compression causes loss of image quality, but the second clip was damaged MUCH more than the first. Questions are why, and what, if anything, can I do about it?

Perhaps the difference in quality is because the second video was shot outdoors in front of a screen of trees and leaves getting blown in the breeze, so there's much more motion than in the first clip, which consisted of one individual indoors, standing on a stage.

Any thoughts???

Thanks!

Hi Warren,

I always use:

File format:

.WMV

Profile type:

Windows Media Video 9 HD High Quality

and get excellent and high quality results every time on YouTube.

The only issue I get is whether the HD or the HQ option is available. I notice that it depends on how I shot it. For example, if I shot it at night or in low lighting, the HD option is not available.

With PD7 it might be worth looking at this tutorial.

Hi David,

Well, I tried your suggestion and, lo and behold the image looks A LOT better!!! Many thanks!

But . . .

The file took a very long time to encode and to upload, and worse, it takes a long time to load onto a user's computer--long enough to discourage people from watching, I fear.

Worse . . .

The SOUND has taken a hit. The piece is just spoken word, nothing complicated, but the Youtube file has a definite warbling or garbling in the audio. Not altogether unintelligible, but distinctly inferior. And that did NOT happen under the other file formats I've tried.

Any further suggestions???

THANKS AGAIN!

Warren,
Perhaps you should have followed the video's instruction I gave.

1. the uploaded file would have been smaller.
2. the YouTube display would have been crisp and sharp* in the HD quality setting.

* depends upon the quality of your footage of course.
