DVD or DVDr: Can you tell the difference?

Kester Pelagius Posted: 04/21/08 13:15:12	Tags [edit]: fun How well can you detect the subtle differences in video quality? Does it even matter to you? Well here's a fun little test I put together. . First up caps taken from an outdoor scene in what looks to be noon time lighting conditions: Second, to help you better compare and contrast here's a poorly lit indoor scene (source caps presented in same order as above): Each of the screen captures above are taken from different video sources. Can you identify which is the commercial DVD release and which is not? Can you determine what the other video sources might be? Good luck! # EDIT: To clarify for those wondering: Yes, this is sort of a trick question. (Obviously only ONE of the screen caps can be from a commercial DVD.) No, I wasn't trying to fool you with #3. I wasn't able to get a exact frame match due to interlacing issues so went with the closest frame possible. For those confused by this I apologize. And, yes, each of the screen caps are really from separate and DIFFERENT video sources. I will reveal all about the screen caps and video sources on Wednesday or Thursday to give plenty of time for discussion and to allow more film fans to have a bit of fun. Psst. You can click on the above images and get a much larger (I mean it's huge) image to compare screen caps with. Last edited by: Kester Pelagius 04/22/08 06:57:01. Edited 4 times.

Everyone agreed the VHS source was both the worst looking and easiest to identify. However it seems the differences in quality between the final two caps were too slight for most, yet the majority of guesses were shockingly accurate. But which screen caps came from what video source? -- Screen Cap #1: DVDr by way of DirecTV broadcast recorded, in SP mode, onto the internal HDD of a Panasonic DVD recorder, prepped, then burned to disc. Screen Cap #2: DVDr by way of an SP mode VHS prerecord, label: Vestron Video, played on a Phillips S-VHS player hooked up via S-Video cable to the same DVD recorder mentioned above. Recorded and burned in SP mode. Screen Cap #3: The commercial DVD.
