One of the questions I am often asked is about when and how to compress videos for encoding to DVD. While the "how" will have to wait for another post, I intend to discuss the pros and cons of compressing files prior to authoring and during authoring.

When I started this blog my intention was to come up with original content, I intend to do that but I also feel it is important to highlight great answers written by other bloggers. I dont want this site to become a pointer to other sites rest assured I will continue to comment and write my own articles. One of the most common issues I hear when it comes to editing, shooting and encoding (in fact a student here at TAFE just said "Why is this still picture flickering on the monitor) comes back to interlacing issues.
Problems present as "shimmering" still pictures, jerky or jumpy moving shots to footage that "doesn't look right". Usually it is caused by multiple software packages treating footage or stills differently or more correctly interpretting the interlaced image differently. I wont keep writing about this as a far more intelligent and eloquent blogger than myself has written an excellent page of information with diagrams etc on this subject.

Problem/Issue:I have been doing some large complex projects in Adobe Encore lately and have found I can get some rendering errors. My footage is imported as quicktime reference files, using an Avid HD CODEC. The menus are quite deep and involve some multiple audio files.
I found that pre rendering the QT ref files to .m2v first could help but this goes against my normal authouring principles, but to get the job out I did what I had to do. Also I found that the longer the project extended over time, i.e. days back and forth, checking previews etc, that the problems became worse. Sometimes I had to individually render each file. Oh and also if you haven't updated to the later software update the renders you have completed may disappear too.
Solution: Create your menus and timelines test and use the interface then save them as templates. Start a new project, clean, use the templates and very quickly rebuild your DVD, remembering all the features etc you put in your first "draft". This wont take long the second time. Then burn. Result, DVD burns fine (hopefully). Also try converting all your reference files to mpg first, seems to help especially with large HD files.
