Problem/File Properties: I made a 20-minute video which combined several slideshows, video clips, and AVCHD clips. I saved the video first as a HD WMV then I made a DVD out of the project.
What devices are involved and their mode of connection?: Lenovo Y550P, Win7, 4GB RAM, Core i7
Project Properties (important): Under project settings, this is what I had...
MPEG files
24 bits, 720 x 480, 29.97 fps
Lower Field First
(DVD-NTSC), 16:9
Video data rate: Variable (Max. 8000 kbps)
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)
Output format: DVD
NTSC
So, if anyone can tell me why my video resolution was so pixelated, I would really appreciate it. Here is a crazy thing...while fast-forwarding through the video, the faster motion actually made the pixelation better (resolution got better while it was going faster)...which baffles me.
Thanks!

Why did you go from one project including one of the more difficult formats (AVCHD) to another difficult format (HD WMV) and then convert the whole thing downwards in quality to DVD?
At the very least, your project properties use Lower Field First -- and it should definitely be Upper Field First to match the original AVCHD (which is always Upper Field First). While I am not saying this is the sole reason for the pixelation, changing field order like that often causes severe pixelation, particularly in fast moving video...

Ken,
Thanks for the quick reply.
The video ia for my daughter's soccer team...a combo of slideshows, videos in .AVI (from Nikon D90), and AVCHD video from my Canon HFS10. So, I started in a couple of different formats...and decided to archive my projects to my computer using HD WMV (This was a random decision, with no basis for the decision except that the quality seemed good). I went downwards to DVD to put everything into a format I could share with all the soccer team parents (I do not know whether they can play anything HD).
I don't know what lower field first means, or is...I could use some video editing 101 in regard to this stuff, but I don't know where to begin.
The video in WMV format looks very nice, btw...not sure if that lends a hand to anything though I will burn a disc with upper field first to see how that turns out.

Hi
Interlaced video
Some video formats are interlaced, that is the frame is split into two, a bit like a comb.
Frame ¡¥B¡¦ and Frame ¡¥A¡¦ also known as Upper Field and Lower Field.
The frames being reconstructed during playback, interlaced.
This interlacing has to be done in order, upper field first or lower field first.
If you get this wrong then the video may show jagged edges.
Interlacing has been about since time began, with the recent introduction of HD, both interlaced and progressive video can be used, progressive using full frames.
DV-Avi format uses Lower field
AVCHD Upper field
Most old analogue camcorders produce Upper Field
Project Settings
You can only have one field order to your project, so mixing AVCHD and DV-Avi is a bit of catch 22.
Which one do you choose?
Well the longest video is a start, saying that DV-Avi may be the best one to convert.
So I would use Upper Field to match the HD video.
If the DV-Avi shows quality problems, recode the video to Frame Based, then add/mix with the Avchd.
Then decide what you are going to make, for a DVD you cannot use the default templates cos they use Lower Field.
Edit the project properties to DVD properties, upper field, then render using Same as Project Properties

I re-rendered the DVD and switched it to upper field first and 4:3 (instead of 16:9). Still very pixelated all through the video. BTW...does it matter upper vs lower field first if it has already been converted to HD MWV? The HD MWV file is what I was working with for the DVD...not the native AVCHD.
I downloaded a power director 8 trial...input the HD WMV into it and burned a DVD...it came out NEARLY PERFECT! Why is this? At one point, it warned me about the 16:9...that I should change it to 4:3 and that is why I changed the ration when I tried yet another burn with VS Pro X2.
I really don't want to spend another $100 for the power director software, but it did the job...I will keep trying for a few more DVDs, I guess. Still seeking help!

Problem Solved: I made the settings "no frames" and 4:3 ratio, and it came out to the same quality as power director...excellent for DVD, especially with up-conversion.
I am going to guess that once I have converted a file to HD WMV that the "upper" and "lower" fields no longer apply since it is in a new file format. Please correct me if I am wrong on that.
Thanks.
