export settings in general
Hello,
I have seen this question posed a few different ways, but none have been specific enough to help me. I have about a 50 minute sequence that I am trying to export. I can’t get the settings to compress the movie much, it remains to be a huge huge file. What can I do to maintain quality yet reduce file size? Trying to get a target size of around 2 gigs or so.
thanks

That’s a loooong video. It’s gonna be a big file no matter what you do to it. To get it small is gonna take every means of degrading the quality you can think of. Why don’t you try exporting it in sections of say 20-20-10? Or even 5-10 min. sections? That way you can keep the quality up and the file size down.

We just finished a project where we taped about 35 speeches, each one 55 minutes to an hour in length. We delivered a DVD and a .wmv. Here’s what the work flow looked like. We used XPress Pro almost exclusively, but one or two were done on a MC Meridian system.
-We exported a QT (not reference)same as source file of the speech (no real editing except titles and adding whatever PPT slides the speaker had), and sent it to our encoding machine. Generally speaking, the files were about 10 – 12 gb. We have a mini-network connecting all our production machines.
-Using Sorenson (the full version), we set up a watch folder to encode the QT’s automatically.
-MPEG’s were encoded to a data rate of 5500mbs
-.wmv’s were encoded at the preset 1mbs stream, but I changed the data rate to 1600, and the size was 720×480.
-Using Encore, I built a first play DVD with the .wmv included as an extra file.
What took us 6 months to do last year took a month. The video looked exceptional!

Thanks for the response,
So how does a DVD maintain such good quality yet never be larger than 4 gigs? Same for other codecs like divx.

The short answer is FM.
Flippin’ Magic.
The long answer is how it’s encoded (variable or constant bit rate), the subject (talking head or lots of action) and even the method by which its viewed (computer or NTSC monitor). The trick is finding what works for you and sticking with it. Even something as mundane as the brand of DVD will affect wether your client can view the product. I’ve used Sorenson presets with a lot of success. The data rate and the I-frame rate are the only thing I’ve changed; I set that to 5500 and 6 to strike a balance between quality and size.
It can be very frustrating. There are times I miss VHS. Your customer copy was going to play in a 1981 VCR and the latest greatest.
