Better Compression---Jeff, Joe?
on Nov 7, 2006 at 2:04:32 pm

Using a digital rapids system to compress to Mpeg2, I then bring my files into Encore 2. Recently I created a looping wallpaper for a client that had some gradients on it, I expected some banding, but by the time I got done it really jumped off the screen how much I was getting.

Now going into the digital rapids I have my compression set to the very minimun. This project was only 1:48. Is there a way to increase the quality, or at least minimize the compression in encore?

Would I have been better off not going into digital rapids, exporting out of the avid as an AVI and then dump the wallpaper into a menu? Or is it better to be in a timeline after going through the MPEG2.

I'm not sure about the transcode settings? Can I change those since I only need to burn 1:48 of material and get less compression then defaults...

Thanks guys

Johnny,

Try exporting as an .avi (DV or HuffYUV) out of Avid and then letting Encore handle the transcoding. One of the beauties of Encore is its Automatic Transcoding, which is 90% of the time a set-it-and-forget-it operation for the author. Encore picks the best compression settings based on the amount of content in your project. The MainConcept transcoder that is used by Encore (and Premiere Pro) is one of the industry's best. [Insert nod here to those who swear by CCE]

If you don't want to do the whole 1:48, then export a representative sample from Avid and try that. However, at 1:48 on a DVD-5, you may start to see some artifacting that you won't see with shorter program lengths. That will be true with any transcoder limited by that much material on a single-layer DVD. But you'll have to look hard. :-)

Thanks Jeff, I'll give that a shot on my shorter more graphic projects such as the wallpaper.

The Digital Rapids is great for the longer stuff, since it's a real time compression, generally that's the talking head things. It's when I do the highly graphic things, that the artifacting/compression stuff starts driving me nuts.

While ago you recommended DVD-Demystified...ordered my copy today.

Thanks again Jeff.

If you can get away with it, try and put some 'stylised' faint noise / grain into your sequence before you encode it - this helps the encoder not produce banding....
