I don't entirely understand your question if your wanting to compare the files just to see if there an exact replica without having to skip through scenes then just open cmd "command prompt" type

---

cd X:\DIR\File.extension

---

replace X with your drive letter, usually C then replace DIR with the directory you want you find where the file is located by right clicking then selecting properties it will show you the target/path the replace file.extension with the file name and the . extension type in your case most likely avi so it will be file.avi then once you are in the directory you need to be where both files are hit enter and type

---

comp file1.avi file2.avi

---

replace the file1 and file2 names with the proper file names and change .avi extension if needed. This will either say

Quote:

---

Compare Error at OFFSET X

---

where as X is the character number there was a difference or it will read

---

Files compare OK

---

meaning they are an exact match in file bit by bit of data.

But what I was asking is what's the details/attributes to judge an avi's quality
i.e. Bit Rate, Dimensions etc.
And what is the best columns to display or software to do this.

Thanks

well that depends on the quality you are going for, for instances you can be running a film at 60+ fps and dimensions 1920 x 1080 <-- (the second block is key to which form of HD you have.) at 16:9 or 4:3 and that can be considered HD video depending on a variety of other instances. All in all it is really hard to explain video and audio as it is something you learn over time not all in a couple of paragraphs although a great place for forums, articles, and software all related to audio and video dedication is http://doom9.net hope this can help you find all you want.
