You're right.  It won't reflect the full encode reality, because many 10.000 peaks will ruin the estimation if your target is max 2500. It makes more sense to encode the sample at the average (with max bitrate specified) and check the average quantisizer using BitRateViewer.

Note: which tool do you use to calculate the average ? A simple calc or something else ?

MEncodeMe calcs the average, but when I need to do it myself I use dvdrhelp java calculator.  But I confess I never took the time to test many calculator.

Lol. I was talking about the avg bitate of you encoded m2v. Calculating the avg birate needs only a regular calc. It's just the number of bits of the file divided by the number of seconds.
No need to test any tool for that

Will the cherry you taste have a better or a worse taste than the average cherry of the whole tree ? It's unpredictable

Do you think that this script can't help us with tunning of differents options, even when it don't be as final encode, you can see if images are sharper or not, etc.?
|
It can help to tweak things like denoise and sharpen yes. But you can do that either in starting mencoder and pres "CTRL+C" when it has already done 2 minutes of video
(or even better, you can look at the video with vlc while mencoder is still encoding it).

I was so much angered like reading it kindly. I will read it again.

But if we want to see a problematic part (water, fog, fire, etc), can we set mencoder executable line with -ss xx:yy:zz -endpos "problematic part time"?
If you use the "CTRL+C" way, only can see the few minutes of your movie, but most important, you need to encode first pass completely.
Same with vlc.
Edited:
If you anytime did something like you say ("CTRL+C" or vlc ways), surely was over 1 pass encoding (as I did it sometimes). But this is like if we are gathering cherries from another cherry field (lower quality cherry field).
This do me think about if you are testing the script and viewing results or are you just talking from theoretical side? (It is just a question, no offense please, you said me once in the past that you always do your test, but I think that in this case maybe you don't)

I think so but I never used this option and don't know what it does (it jump to a particular point in the video ?)

NOT AT ALL
The sharpen and denoiser result is the same whatever the pass. The only diff between pass1 and pass2 is the bitrate repartition, so you can trust the result of pass1 for anything that not concerns blocks/pixeliszation of the frame.

Keep you pencil and start taking notes :
ALL
You can drop the pencil and relax
All was said in my previous post in fact : you can test anything that does not deal with pixelisation. DO you know a filter that deal with that ? No.
Only the min/max bitrate are involved in this matter.

No it is not because :
1/ as I told you you can test a script simply by interruptiong mencoder after the first minute or two of encoding
2/ as you told me you can want to see a particular scene and go directly to it by using the option you pointed.
Using you script will take much longer than 1) and won't satisfy the needs in 2).
So... still useless. Sorry

This Thread has become splitted as It went totally out of its purpose/topic.
The further "colorproblem" posts can be found here so Prodaters Thread is "cleaned up" now :
