GSpot Question

[MourningStar]

This nifty little program was given to me by someone long gone that was helping me troubleshoot a video problem. Anyways ...

Is there information provided in one of the GSpot fields that will inform me of the video's resolution (which I am assuming means display/picture quality) without viewing? Say, I have multiple choices of the same movie. Many times the author provides a lot of specifications of the video. Through trial & error I have learned that file size and frame size do not have much to do with video quality. Also, if GSpot is not the proper tool to address this, please let me know of another or if there is no such tool that can make such a determination.

-thnx

thnx, suggesting alternate s/w is nice, but I want to know the exact spec./combination of specs that will address my concerns.

That about sums it up. Mediainfo is not going to tell you any more as far as "quality" goes. Beauty is in the eye of the beholder.

If you know the source spec, it is easier to predict "picture quality" through various codec recode settings but source quality dominates.

As others have mentioned, MediaInfo shows more information about more file types. GSpot shows you the resolution of many file types. But that is only part of the "quality" of a video. It also shows a few things that MediaInfo doesn't -- at least for Divx/Xvid AVI files (GOP details).

ok folks. responses thus far have the populace here voting for my previously stated "no such tool for this exists" option. I was hoping that video quality could be thus analyzed from a 'numbers' point-of-view. You know, like how one can 'know' that an mp3 file will be of higher sounding quality the higher a 'certain' spec. number is. hmmmm ...?

Well there is always the ratio of resolution and the filesize. A movie @ 700 MB may look OK at 640*272,
but look terrible (blocky, lacking detail) at 720*304.
Mediainfo gives this info.

GSpot reports a "Quality Factor" (labeled Qf in the UI) -- the bits per pixel of the video. That's a rough guide to quality. But again, different movies, codecs, settings, and captures can cause very wide variations in compressibility. So just because you find one video has a higher Qf than another doesn't mean it's better visually. Really, the only way to know for sure is to look at the videos yourself.

That settles that, thnx!
