Apologies, my mistake. Indeed you are correct, pretty well anything would be better than a composite feed.

There are no significant bugs in our released software that any significant number of users want fixed. … I’m saying we don’t do a new version to fix bugs. We don’t. Not enough people would buy it. You can take a hundred people using Microsoft Word. Call them up and say “Would you buy a new version because of bugs?” You won’t get a single person to say they’d buy a new version because of bugs. We’d never be able to sell a release on that basis.Bill Gates. Focus Magazine No. 43 (23 October 1995)

[Ben Wharton] “Hmmm – for such an expensive piece of software, one that appears to not create CBR files, I’d say either the software was screwy or I’m misunderstanding something about its use / monitoring.”
Hardly expensive, I use software costing 10x as much and I still cannot rely on exact file sizes at a given datarate for certain codecs.
Remember that ‘Constant’ does not mean ‘Flat’. Flat datarates are only really available with I-Frame only formats. CBR simply means ‘keep a average rate of xxxxKb/s over a certain period of time’, you may find that one of the frames is 1kb and another is 100kb
You’ll find that more capable formats/codecs will maintain far more accurate datarates. Flash is a crap format for video despite its popularity.

Using the bandwidth calc here https://www.digital-rapids.com/layouts/bandwidth_calculator.html the file should be coming out at 810 MegaBytes, a slight difference from your calculation.
If we assume that the rate control of the Flash codec or indeed epsisode is not perfect, and you have to have the file at exactly the size you want then you should compensate by lowering the datarate in episode.
It’s a bit hit and miss but….

Why are you using Toast and not DVD Studio Pro?
Compressor creates two seperate files as that is what one would use when creating a DVD.
You need to select Program Stream of you want one (muxed) file rather than Elementary Stream (seperate video and audio)But if you use DVDSP, stick to Elementary.Compressor is much higher quality than Toast (which at the end of the day is just a great disc burning utility – it’s not much good at any kind of transocde)
Don’t use Quicktime pro for the encode, it’ll look rubbish.
Use Qmaster – it’ll speed the transcode up

That looks very nice indeed.
What was your storage setup for those tests Craig?

[Chris Blair] “You’d basically be saving the a generation and a transcoding pass since you’d elimiate recording to tape (1 generation), and the transcoding from analog to digital capturing it into your NLE.”
Are you sure?
The signal is actually digital data as soon as it leaves the cameras sensor, if CCD, and then to the ADC (Analog to Digital Converter), but is purely digital if it’s CMOS based.
Whether it then goes on to digital tape as digital bits or leaves the camera via the digital output as digital bits, they’re still the same digital bits, so there is no generation loss.
With digital material if you transfer from like to like, there is no generation loss or transcode (in theory). 1=1, 0=0, 1=1, 1001001=1001001 and so on.

Are you sure you are using CBR not VBR?

[Kim Gwydir] “Then it gives me an options button which leads to a pop-up box that gives “optimizing for streaming” I assume I should check that?”
Not you don’t need to check that as you are not streaming the file but just taking it into Media Encoder

1. Yes, it’s a two step process.
2. Export as a .mov and choose the PhotoJPEG codec at 100%.
3. Yes, use Episode rather than Adobe media encoder

If Quicktime is installed on the Avid use the Animation codec or PhotoJPEG at 100% quality
