RV10 Curve Analyzer v1.0

[Dark-Cracker]

Hi,

i have release a little tool i have used when i need to compare the differences beetween some rate control settings.
you select the .log file generated by producer at the end of the second pass and it draw a chart with the curve of each .log file.
it can also display the over/undersize and avg quantizer.

hope it can be helpfull.

HOW TO USE :
------------
- encode your sample with the new RC enabled + 2 pass mode
- select the .log file generated to analyse it
- select the next .log file to compare it with the first file
- .... u can add how many .log file u want to compare (less than 26 :) i have not add support in the excel column after the Z letter :) )
- u can click on the desired .log file and click on "Show statistics"
it will show u a percent of under/oversize and the avg quantizer.
- or click on "draw excel chart" wait and it will export the data in excel.

Warning :
- Excel column max value is 65536 lines so u will have an error if there is more than 65536 frame in the .log file.

- the last frame information is missing in the .log file so i have use last frame = 0 so under/oversize and avg quant are accurate at 1 frame near :) .

EDIT : work with Excel 97/2000/2002

Enjoy :)

This is a great visualization tool for the various scaling options you offer, D-C; to see how bits can be saved during the most intense action, where perhaps it is hard to see the quality improvement a great number of bits are sacrificed to achieve. I think I have to re-evaluate my default choice for the new rate control, and perhaps use one of your Alt_CC scalers instead :D

i have use a lot of chart under excel to compare the curve because it's not always easy to compare some scene only using your eyes.
and i have code this tool to automate all the process, i am happy to see this tool can be usefull :) and that my altcc function too :)
