Don't worry, I'm working on a new formula where you take 3 or 4 short samples and the curve for your movie is automatically determined. :wink:

That is a very good possibility. I used 352x240 for my tests.

The problem I see with these values is that your CQ100 seem way out of proportion with the CQ0 and CQ50 values.

Using the scale I had posted before you should only have about 17.778MB and 1194 as...

This was my point before and it is still true. For prediction, average bitrate and filesize will work equally well. The reason that average bitrate is nice is because you don't have to first...

Just place this function at the bottom of your script or in another file and import it.

Then at the bottom of your script , just before SampleClip or Sampler place Prediction()

You are correct. I gathered the values in my table by averaging the numbers from 4 movies. None of the movies was exactly these numbers.

All right, I think I am a convert.

You can use file size like I said, but who cares? A sample of ANY size can be used with the kbps method. I just did Shrek and found out how good this actually...

Kwag,
Also check out the SampleClip function I created. It allows you to shorten your sample by any factor you desire. It should make it easy to produce a smaller sample for your tests.

For...

Kwag,

Actually I think that your formula may be good. I was just saying that it should be able to work for both average bitrate and filesize.

So when you did your prediction did you start...

I could be wrong, but I don't think that there is any difference using the filesize and the average bitrate.

Say a 60sec file of 8,682KB and its average bitrate is 8682/60=144.7KBps

If we...

I have already done this with samplepoints at every 5 CQs. The graph is not linear over the entire CQ range. Here is a graph:
