to interlace or not to interlace...that is the question.

Here's the rundown:

1) made a title using blufftitler and rendered as uncompressed avi with alpha channel

2) opened the title in VV5 and added some artbeats backgrounds, added audio

Now...do you think I should render as interlaced or non-interlaced. I plan on using the 15sec. spot as a first play in DVD-Lab...the main title will be interlaced.

What would be the best bet here...interlaced or non-interlaced? Am I going to have any vts problems with DVD-Lab? Are there any down-sides to just rendering the whole project as non-interlaced?

On what will the final product be viewed--a television or computer monitor?

Hi Red,

Since you said that you want to send this to TV, you can really do it either way, however, remember these limitations....

Non-interlaced ( no lines visible in picture ) is usually always preferred since the video quality itself is much "finer" than interlaced ( scan lines visible in picture ). However, unless most of the intended audience has newer televisions ( computer monitor types ), they may not be able to view it as you intended. Interlaced on the other hand is the NTSC television standard, so if you want to make sure all of america can view it on their TV's then use interlaced. If on the other hand your viewing audience is using Progressive scan, HDTV, or computer monitors to view your title, then the preferred way to go would be to use non-interlaced. and two-thumbs-up for using an uncompressed AVI as your final render !!! Hope this answers your question.

Non-interlaced will have a temporal resolution of 30 frames per second. (or 25 fps PAL.) Interlaced video will have a temporal resolution of 60 fields per second resulting in a much smoother motion. As far as fluid and smooth motion is concerned, interlacing is a GOOD thing.

May I refer you to my post from some time ago on the subject:
