Good vs Best Render? (For Broadcast TV)

will-3 wrote on 4/23/2008, 5:39 AM

When rendering to an AVI NTSC/DV file on the hard disk... or to Mini-DV tape for TV... for ultimate playback on Broadcast TV...

(We render segments to AVI on the Hard Disk... then render the show to tape)

What is the difference between Good & Best?

I'm guessing Best takes more time.

I wonder if the general audience will notice the difference between Good & Best on their television sets?

Thanks for any comments.

Good vs. Best generally only makes a difference when the size of the image is changing. If you're rendering SD to SD then there should be absolutely no difference at all.

Here's the full blown answer.

The biggest difference I see is when dealing with still images, especially if they have any panning motion.

I can definitely see a difference between Good and Best on rendering still images with motion.

thanks jetdv

some good info there

I suppose all these settings mean nothing if your bit rate isn’t above 4000

I am working on live feed and ultimately bit rate is what counts the most with motion clips

I suppose the MPEG2 options on the guide Project as suggested on the guide right above (link offered by jetdv) are automated, aren't they?

I'm not certain I understand the context of your question however here's my best answer.
The settings described in jetdv's guide determine how the frames are rendered and presented as input to the mpeg-2 encoder, or any renderer / encoder for that matter.
The Preview/Good/Best project settings will be overriden by the setting in the Render As dialogue box. The only exception is for nested project. If a project is nested then the output from the nested project is rendered at the project settings of the nested project. This is a very useful feature.

If you have a section of video that requires Best because of scaling (say your opening titles) and the rest of your project only requires Good as it's at the same resolution as your output then considerable render time can be saved by nesting your title sequence into your main project and rendering / encoding the main project at Good. The nested titles will be rendered to the main project at the nested projects projects setting which you make Best.
Hope that makes sense.
