Video looks weird when burned on DVD

The QuickTime file shouldn't be a problem, it will get converted just like anything else that isn't in DVD-compatible MPEG2 format.

How long is this video? If you don't need to go to 4000Kbps, I'd go higher to 6000Kbps or 7000Kbps.

And have you successfully used this particular media with your burner and DVD player before to rule out media incompatibilties?

the quicktime file is approx. 70 mins (I think I said 10 mins in the other post, that was a typo, it was 70) and is integrated into a project that is 1hr 45 mins, so the 4000 bitrate is necessary, I am using the same media that I have been using for all my videos that I have done, so I don't think it is incompatible media (Maxell DVD+R, and +RW's)

What is the frame-rate (fps) of the .mov?

Under the video properties screen it says that it is 29.970 fps

I have come up with something that may be my problem. I just would like confirmation before I do over 15 hours of rendering. I used AVID Xpress Pro to produce this 70 min segment, because of some of the functionality differences from AVID to UVS9, I had to use both programs. The Quicktime is exported from AVID (AVID can't do AVI's due to a 2gb file size limit, I am running NFTS (i think thats what it is called, all I know is that it is not FAT32), I used the AVID Codec when exporting. Is it possible that ULEAD can't read the AVID codec properly, and that is causing the jerkiness, If so, I will re-export without using the AVID codec (that can take awhile, a 2 min test export took 30+mins, so a 70 min video would take almost 16 hours) Can someone please confirm if I am on the right track.

I don't think AVID itself is the problem, they don't provide their own QuickTime codec -- that's still an Apple product.

When you wrote you would export without using the AVID codec, what file format / codec were you considering?

It has the option to export to Quicktime with or without "AVID DV Codec", the resulting file for the 70 min video(with AVID codec) is a bit over 13GB. I can't output to anything but .mov I am not quite sure what codec is used when I de-select "use AVID DV codec", I may end up just trying it to see what happens. Under the properties for the video in VS9, It says "Compression: AVID Codec" As a general question though does a jerky video often result when Ulead can't read the codec.

OK, what this is is the use of a MOV file as a container. QuickTime in that sense is similar to AVI, it can contain audio and video compressed using either its native format, or a third-part plugin like the AVID DV codec, or the Sorensen codec. By choosing AVID for the codec, you aren't encoding to QuickTime, but to DV contained within a QuickTime container.

The inability to understand a codec (genrally because it isn't installed) would result in not being able to open the file, not jerky playback. Having an old version installed might result in a lack of backwards compatibility and intermittent decoding problems.

What happens when a codec decodes / encodes a video is that it goes from either its native format to an uncompressed format, or the opposite. It should never result in jerky video.

I still think we're missing something fundamental.

ok, I finally finished the creation of another .mov without the AVID DV codec, just to see if the same problem occurs, it does, but it is a bit better, still unwatchable, but better. I have managed to explain to this person that I am having trouble, but he would like it ASAP, what settings should I post to help in the diagnosis of this continuing problem? Can ulead read QT reference files? If so,I will try it again using a QTRef.

Just a thought. I think you maybe suffering from a problem called "Video Format incompatibility." While it is assumed that conversion from one format to another should be basic and simple, it is not always the case. I've had a similar problems with graphic file formats (though, I suppose, unrelated to this forum). Someone out there can give you a better idea than I have. I have spent some time studying file formats and have found that, in your case, even though it may be a .mov file (as per the program you're using) it may not be a 100% compatible .mov file. Do you get my meaning?

The best solution would be to redo the .mov clip in .avi (one of the more usual ones) then combine with other video material (already in AVI) then convert to MPEG and burn.

Unfortunatly AVID can't export any .avi's that are bigger than 2GB, Even though my file system is NTFS. .mov's are the only option, unless Ulead can accept QT Reference Files, can it?
