Want to check the video quality of all my video files

[Plecto]

Hi. I have three hard drives filled with movies and different series. To assure a certain standard for my video files I would like I program that automatically checks the video quality of my media files and then lists them so it's easy for me to see what I might want to delete or replace. The days of PAL and NTSC are gone and HD monitors, TV's and projectors are everywhere so I thought it would be a good idea to assure that I'm actually getting the most out of the viewing experience. Does anyone know of a program that does this?

Hi Plecto, this will help:- MediaInfo

That's a very good program for listing the file properties but the question of quality is anothe matter. Are you talking about the quality of the content or the actual viewing quality of the subject? Either way this is subjective and IMHO can only be decided by you viewing a sample of each file!

Well, I'm not asking the program to give a review of the movie and then give a grade from 1-10 But I see what you mean about subjective video quality. I don't know enough about video decoding to know how many parameters there are, but I guess resolution and stuff like bit rate affects the quality a lot? Even though it won't be perfect, it can still be a good indicator of how the quality is, no? Then again, I've seen some 1080p movies that were only 1.5GB in size and still looked perfect to my eyes on my 27" samsung monitor. This make me wonder as there HAS to be loads of information lost compared to a full blu-ray movie.

Hi Plecto
I shoot short movies in HD all the time. I can burn the Blu-Ray files to a standard single sided DVD and get just over 30 mins. This plays through a Blu-Ray player onto a 32ins TV perfectly. It is the same as you would get using a Blu-Ray disc!
So far as a generalisation is concerned, remember there are about 800 different formats for video imaging and each one will be a different rate of compression hence quality loss.. AVI is one of the most commen but this is more a group name as there are dozens of formats that come under the AVI name. Every time a clip gets rendered there is quality loss much like saving a JPEG. Every time you save a JPEG after say editing the levels or saturation it gets further compressed.
So I think looking at the clip is the only sure way.
