Uploaded video to You Tube is very pixelated

Hi Guys I recently had to reinstall Moveie Edit Pro 14 which I 've used succesfully for a few years. After compiling various video clips from a Canon solid state drive ( SD ) camcorder I burned the project to DVD succesfully. I played it back via dedicated Samsung BluRay player onto a Samsung 40" LCD and it looked great with great clarity. But when I tried to upload the project which is only 2 minutes to You Tube via MEP nothing happened. So I uploaded the movie via You Tube directly and whilst it worked the quality of the video is appalling with a lot of pixellation when viewed back on my PC 19" monitor. My first question is any ideas why it wont upload to You Tube via MEP? The bar at the top says 'downmixing' but when that finishes nothing happens whereas previous it would take me straight to you tube login page. My second question is having uploaded the video from within You Tube direct from the directory I've save it to why would it be so pixelated but in MEP and on DVD the quality is great? I'm suing Vista on a dual core PC and have successfully uploaded good quality video via MEP but that was before I had to the reinstall. Many thanks Tony London UK

Hi Tony.

Two suggestions: don't use the built-in uploader within MEP; it rarely works, especially as you appear to be still using quite an "old" version of the program.

Second, I can't directly answer your question about the pixellation without knowing a little more about the actual file you are uploading (format, size etc.) but YT itself does publish a very useful guide on formats to use for uploaded videos. (You should be able to find it in the YT Help section: "Getting Started: Optimising your video uploads".) I do quite a lot of work with AVCHD footage but for YT I export that footage as .mp4. Even after YT has "processed" it the results are always pretty good, no pixellation.

HTH.

The way I do it is - I try to match the requirements of my audience.

F.Y.I. - Youtube Specs and recommendations are :

Video
Resolution Recommended: 1280 x 720 (16x9 HD) and 640 x 480 (4:3 SD)
There is no required minimum resolution - in general the higher resolution the better and HD resolution is preferred. For older content, lower resolution is unavoidable.
Bit rate Because bit-rate is highly dependent on codec there is no recommended or minimum value. Videos should be optimized for resolution, aspect ratio and frame rate rather than bit rate.
Frame rate The frame rate of the original video should be maintained without re-sampling. In particular pulldown and other frame rate re-sampling techniques are strongly discouraged.
Codec H.264, MPEG-2 or MPEG-4 preferred.
Audio
Codec MP3 or AAC preferred
Sampling rate 44.1kHz
Channels 2 (stereo)

YouTube recently began offering users an option to view content in high definition- 720p resolution (when the source upload supports it). Please note, we are currently experimenting with this feature and optimizing it accordingly, so we can't guarantee that your videos will always be transcoded into this format with this user option present.

For an example of a video being streamed in 720p resolution, please click this link and then click on the text toggle "watch in HD" located beneath the right hand corner of the player.

How to best upload widescreen videos

Originals Please!

The less a video is re-encoded prior to uploading, the better the resulting YouTube video quality. We encourage you to upload your videos as close to the original source format as possible, with a minimum of intermediate re-encoding steps. Each re-encoding can generally degrade the quality of your video and create some specific problems too, which we'll address below.

Aspect Ratio

The aspect ratio of the original source video should always be maintained when it's uploaded: Uploaded videos should never include letterboxing or pillarboxing bars.

The YouTube player automatically adds black bars so that videos are displayed correctly without cropping or stretching, whatever the size of the video or the player. For example, the player will automatically add vertical bars (pillarboxing) to 4:3 videos in the new 16:9 widescreen player size. If the player is re-sized (when embedded on another website for example) the same process takes place, so that 16:9 videos are letterboxed (black bars top and bottom) when the player is sized to 4:3, for example. Similarly, anamorphic videos will be automatically letterboxed when shown in either 16:9 or 4:3 sized players. The player can only do this if the native aspect ratio of the video is maintained.

If letterboxing is added to a video before it is uploaded (to create a 4:3 video from a 16:9 master for example), the widescreen player will add pillarbox bars too, resulting in black bars all around the video (windowboxing) and a bad viewing experience (see the diagram below).

.
Frame Rate

The video frame-rate should be the same as the original where possible - up-sampling from a 24fps original can cause judder artifacts for example. For film sources a 24 fps or 25 fps progressive master yields the best results while videos that have had a re-sampling transfer process applied - such as Telecine pulldown - often result in a lower quality video.

Resolution

High-definition videos are the preferred format for ingestion which result YouTube videos of the highest quality currently available. It also means your video can be upgraded as new formats are developed on the site.

Testing

Since there is no facility to re-upload videos, it's important to test your audio and video quality are satisfactory before you release your video publicly onto YouTube. Once a video becomes popular, the number of views, user ratings, user comments and other community data, cannot be transferred if another, higher quality version of the same video is uploaded. Make sure you get it right!

File Size

YouTube Partners have a limit of 20 GB per video uploaded through a web upload.

I usually will download the video to my desktoo - test it and then upload it to Youtube.

I hope this helps....
