Same file size 1080p or 720p? What will produce more detail?
Has anyone experimented with the same final file size and seen what a 1080p and a 720p produces as far as fine detail in the resulting video?
If so, what were the results? Thanks in advance to anyone that has done this experiment themselves. It will save me hours of encoding time to find out myself. Last edited by foxyshadis; 17th December 2014 at 02:34. Reason: Restore post |

Here's a little Avisynth snippet which you can use to compare 1080/720: Code:
#Test resolution loss for 1080 -> 720 a = last Spline36Resize(1280, 720).Spline36Resize(1920, 1080) Interleave(a, last) |

For Avatar?
Maybe if you resize to 360p for a mobile device. The theatrical cut, that is. NVM the extended edition. Just thinking about creating a DVD for portable's sake is too much to think about with DVD-9. Even going to 704 anamorphic on 2 or 3 DVD-9's is asking a lot.

Was that post really necessary? Just because you view things differently than I do does not mean you need to look down your nose at what I am trying to accomplish.

I'm not a native English speaker so I don't know if his response is offensive. But 4GB for Avatar is too much of bitrate-starving, especially if you think about keeping 1080p resolution. Don't know what you're trying to accomplish, though. If you want your encode look pretty... bad then you just go for that size.

We could say the same about your attitude.
No one was looking down their noses at you. That's just your negative attitude. Sorry you perceive things that way. But, so far, I'm not disagreeing with what anyone has said. Except for you. So why don't lose the 'tude and try make yourself more clear and open to others.

DVD-9 would definitely make 1080p a better experience than 720p. 360p, maybe if you were doing a CD-ROM . |

Avatar has very low noise which will let it get away with less bbp than other titles. That ABR is on the threshold where I'd want to see it both ways to know which would be better overall. There's also intermediate options like 1440x anamorphic. My major point was that 1080p wasn't obviously crazy too high. It might well not be the optimal frame size for that content and that file size, but 1080p certainly would be better than 360p or even 480p. |

I'm restoring the posts and closing the thread. While the topic is interesting, and some people revel a challenge, it's best not to have it derailed by thin skins and naysayers.
This might be a good general topic for a new thread, though: How to find a good tradeoff with a low bitrate? A lot of the previous discussions centered on BPP and why it sucks or how to better estimate it, or using full compressibility checks, but someone might have a good idea on how to measure and optimize detail loss. Anyone feel like a contest? |
