Input video file format that allows Encore to build a DVD without conversion

Question

Hi,I've been working on some DVD projects and there's one thing boring me: conversion time!Encore takes too much time to encode a vídeo file (about 10 hours per DVD project only in encoding time) with a acceptable quality (which requires Render at Maximun Quality option to be checked) in lower bitrate settings. There is no way to increase the bitrate quality due to DVD size, but even increasing the quality to its maximun, the encoding time takes about 3 hours to complete.Theres's some free DVD Authoring softwares that do this job decently in a quarter of this time of 3 hours, but they don't offer the possibility of producing a elaborated menu in After Effects, for example.So, i've noticed that Encore creates after encoding process, a vídeo file with .m2v extension (MPEG2-DVD) and a ac3 separeted file. Importing this two files to Encore, makes it to build the project withou encoding the files again. So, is there any way for me to create this two files outside Encore and then importing them in order to avoid Encore to encode them before DVD building? Which are the specifications of m2v file that Encore creates so I can find an external software that can produce these files faster or even in another computer with more processing power?Thanks in advance.

Edit in Premiere Pro and export from PPro using the MPEG2-DVD preset, which will create the audio and video files you need

If you export from PPro with "legal" video and audio data rates, your two files will not need to be transcoded again in Encore

Somewhat dated now, but still a lot of good information

CS5-thru-CC PPro/Encore tutorial list http://forums.adobe.com/thread/1448923 has lots of tutorial links to help learn

I would add to John's suggestion that if your original material is HD, in the PR/AME export settings, make sure you set pick the correct preset in the MPEG2-DVD format (e.g. widescreen), and then set the cropping to "scale to fill." PR/AME produces reasonable quality. The bitrate setting is the big issue.

in lower bitrate settings.

This suggests you are putting a lot of video onto the disk. Much over an hour will lower quality.

Learn to use a bitrate calculator:

Or here's a version of Jeff Pulera's shorthand:

When encoding MPEG-2 DVD in AME, a good way to estimate encoding rate is 560/minutes = rate. Your example of 115 minutes comes out to about 4.8 data rate, maybe go 4.7 for safety. For shorter vids, consider 8 as a max rate for video (audio gets added on top of that).

When you "import as timeline" to Encore, the asset should show "do not transcode" in the DVD transcode status column.
