:mrgreen:

I just got a diff of .83 (see my previous post ) on another sampler, also at 352x480 8O.
So I'm running a sampler with the chart value * .83 to see if it hits the same file size that...

Right, that's what I thought. That's exactly the difference I got.
Now wait a minute :!: , coincidence :?: or could this mean we have a constant factor :idea: 11.4/13.5 = 0.84 so 0.84 * (*CQ) in...

Hi ren,

Yes, the resolutions throw off the curve completely 8O.
I guess this exercise did turn into a "crap" ( for my posts :cry: ), because the method is very tightly integrated with the MIN,...

@Ren,

Take a look at the numbers and see if it now matches close to what you had encoded before :wink:

@Tenra,

I think that what we need is your "Scale" factor table, but instead of the center being 50, it has to be CQ=100 equals the factor of 1.0
So then we encode the sampler at CQ=100 and take...

8O Are you using the same script you used for CQ=62 :?:, or have you made any changes :?:
Can you run your sampler again with a CQ of 47 to see what is the actual file size :?:

Hi ren,

Open your .d2v with MovieStacker, and look at the suggested average bit rate. Say it is 890Kbps. With your numbers above, you would take the average produced with CQ=100. So 890/1767=50.36...

Hi Tenra,

Your formula works very good. It still has to do several runs to reach a CQ value (that's not your fault :) ), because of the nature of CQ vs. file size non-linearity. The thing I see...

Hi titans_ca,

Great graph and test :). The only problem I see is that this is on a one step increment of CQ. The CQ vs. file size is not linear if you try CQ values from 1 to 100. It's (sort of)...
