Poor quality DVD from a 1920x1080 movie

Lotito wrote on 3/5/2014, 6:24 PM

I am trying to make a DVD from a project containing a .mov in 1920x1080 / 16:9 format.

To make a DVD that file needs to go to 720X480 / 16:9 format.

I have no problem burning that DVD but the quality is far from satisfatory, a lot of traces mainly on action scenes.

I tried to export that HiRes video to many formats supported by ProX5 before go to burning but with no better result.

Thanks for any help

Hi.

First, it is important you understand that any DVD can only ever be SD (Standard Definition). It is a common misconception that DVD can be HD (High Definition). In fact only AVCHD DVD (maximum approx. 30 minutes playing time and can only be played by a Blu-ray player) or full Blu-ray ( which must be burned to Blu-ray disc and can, again, only be played by a Blu-ray player) can fully reproduce HD footage.

You mention a "lot of traces ... on action scenes". I wonder whether this is interlace artifacts? Does it look as if the "edge" of the moving object looks a little like a staircase? If so, you need to check the interlace properties of your original video file (Top Field First or Bottom Field First or even Progressive) and make sure that VPX5 is working to the same "standard".

HTH.

Thanks Jeff !

I will investigate the interlace properties and the VPX5 options you have mentioned.

I have tried some other programs like AVS to convert the movie but despite the program does a good job, for a while the results are not any better, maybe I should check the quality of the original movie too.

Would you recommend some BluRay Recorder for my computer ? It is a MacProTower 8 core Intel running Windows 7.

Thanks Again

Also note that if you are playing a DVD on a HD TV you are upscaling the 720 * 576px image to for example 1920*1080 - this makes viewing poor in quality. How poor depends on the quality of the upscaler.

A small improvement can be obtained by increasing the bitrate setting in the Burn dialog to the maximum possible that will allow the movie to fit on DVD.
