Hi there,
After wasting 12 DVD's and 3 hours i decided to come here and see if i can get assistance. :lol:

I made a nice animation that is 1920px x 1080px - best quality (no compression) AVI file - looks great on my CRT computer monitor.

Here's whats happening:

1. It doesn't fit my 37" HDTV (height wise), what should be the resolution for all HDTV screens?

2. While converting to a DVD the quality is getting worst :roll: do you know of a program / technique that is used to convert graphics/animation to HDTV (discovery channel style etc.)? the programs i tried use MPEG compression while converting to a DVD format.

There has to be a RIGHT WAY to do this.


Thanks! 8)

if you want to keep it HD you have to burn to some version of HD disc not SD DVD.

As for ...
1. It doesn't fit my 37" HDTV (height wise), what should be the resolution for all HDTV screens?
... that's odd.

Brand and model... are you hooking this up directly to your PC as a PC resolution or via analog component video set for 1080I or 720P?

Thanks for the reply.

My PC is not connected to the TV, i just burn the DVD's with it and created the animation on it.

When i play it on my regular SONY DVD player (not hd) it should show at least a DVD crisp quality animation, however it is a little smaller than the screen (37" sharp aquos) - height wise... width is ok. (i rendered the animation to 1920 x 1080)

And...
The quality looks like it is compressed (pixelated around the edges)


Thanks.

Hmm...

This height problem is likely due to the 16:9 aspect of 1920X1080 using square pixels.

4:3 DVD is based on 800X600 and 16:9 DVD is based on 720X480 but if you do the math you will find the aspect ratio is 1.5 rather than 1.78/16:9. 16:9 DVD is an anamorphic process which means it is not based on square pixels.

Either way, SD DVD cannot preserve HD fidelity so the aspect appears to be a side problem...
