XviD Stats Analyzer

Yuri Khan · 1st October 2005, 20:38

Hello everybody,

I was in the middle of a difficult encode, and was wondering which parts required the most bitrate. Looking at frame sizes in the .pass file, averaging them in Excel, switching to VirtualDubMod to look at a particular frame… Surely there has to be a better way?

So I have made a tool to simplify analysis of XviD .pass files. To put it short, it displays a scrollable graph of frame sizes (both original and averaged over ~200 frames), and has a simple built-in player that plays selected frame ranges.

I am now releasing it under GPL, without any warranties but in hope that it will be useful

A more detailed description, screenshot and download are at http://stats-analyzer.gorodok.net/.

P.S. My apologies to MoonWalker for almost conflicting names…

Very nice indeed, Yuri ! Thanks for your generosity.

Man, where've you been all those years? It took so long for a nice little tool to appear, doing exactly THAT.

A big Thank-You!

Okay, here’s the first update

Code:

0.1.1.0 (2005-10-02)
  [-] The graph window had a 65536 frames limit, after that
  range selection did not work. Rewritten.

  [+] Added keyboard controls to the graph window.

  [-] Fixed an integer overflow in bitrate threshold initialization.

  [×] The frame size axis tick label intervals are now selected 
  depending on window height.

  [×] Narrowed the bitrate averaging window down to ±15 frames to 
  speed up stats loading.

Thank you very much, Yuri! Your analyser is very useful piece of soft!

Aproros, can you please make graphs scalable along X axis (for ability of viewing entire graph at once)? It will be much easier to quick find difficult places in movie.

Thanks Yuri. Really great tool.

Nice program, thanks!

Version 0.1.2.0 (2005-10-07)

Added graph zooming. (Idea by Elic)
Added ability to base gridlines on frame sizes in bytes per frame or bitrate in kbits per second.
Added ability to set bitrate threshold in bytes per frame or kbits per second.

> Added graph zooming
Thanx! I feel myself much more comfortable at once.

not as great as yuris solution, but if somebody like it fast and simple:

if you looking for the 10 scenes with highest bitrate

xdstat video.pass /stat=10

if you clip has 30 fps (25=default)

xdstat video.pass /stat=10 /fr=30
