DIVX Quality

[manny_s]

I have a divx avi that I want to burn to vcd/svcd. How do I find out the qualtiy of the avi so that I can decide whether to split it into 2 parts for VCD or 3 parts for SVCD?

Thank You

The best way to judge the quality is to watch it and let your eyes be your judge.

Thank you for your recommendation. Unfortunately, I have no way of watching the movie until I put it on VCD/SVCD.

Do you know how to discover the actual quality of the AVI so that I can make an intellegent decision on whether to burn this to two or three CDs?

Why can't you watch the DivX on your computer?

Unless the DivX in of a very high standard, chances are is that it has already lost enough quality to make a 3 cd S/VCD unnecessary.

I can watch it on my 15" computer. This will not tell me how it will look on my 51" TV. Since you allude to a very high quality divx file, perhaps you can tell me how I would determine whether it was high quality or not?

[Dave B]

OK. A simple way would be to compare the filesize to the movie length.

A two hour movie encoded to a 700MB DivX is not going to need a 3CD SVCD to do it justice.

[manny_s]

That certainly is good advice. Can you point me to a technical reference that would help me determine exactly how to compare the quality of SVCD to DIVX so that I can make an informed decision for divx avi's that aren't 2 hours long or 700 MB?

Or are you just speaking from experience and there is no technical reference?

[Dave B]

Unfortunately quality is subjective and while some people may be happy with low res or low bitrate video, others are not.

If I were you, I would encode 30 second batches from the DivX with some different settings and see which one gives you the best quality for the size. Use a CDRW and test them out on your TV.

Remember that the quality will always be limited by that of the source video. If the DivX isn't good quality then its not going to get better by re-encoding it - regardless of the settings.
