Re: Is there a way to determine whether a video is lossy .mpg sourced?

Well that looks fine exept the 8000 can look questionable as that that tells me it is Constant bitrate(CBR).
This is not as good as VBR(variable) as it was recorded/transfered using only 1 pass.
Too much bitrate at wrong moments where not much is needed can cause blocking.
It could mean it was re-encoded using CBR but thats not concrete evidence.

Everything else checks out though.(the Mp2 audio would of been @224 standard not 384.....that could be bad setting up though during transfer)
What do your eyes tell you?
Example: I recently recorded a TV re-broadcast of Sky live at Rockpalast.To me the image of the broadcast looked like a processed VCD.Maybe it was.Maybe thats all that exists now.


Remember that in reality there is no such thing as DvD quality as DvD stands for Digital Versatile Disc,not Video Disc.
You can't get x IN DvD ,only ON DvD
The disc is only a archive storage tool.
What counts on the quality of it is the resolution,bit-rate & copy generation.
Your eyes will tell you but they have to be trained

I will say about the jpg you posted that i cant see many "compression tells" so it maybe lossless(for want of a better term) ..but just a higher generation copy.That's why the contours are not sharp anymore.


My personal opinion........re-encoded because of CBR & Mp2 @384

Hope that helps you a bit.
