Genius encoders themselves require side by side screenshots with the Bluray source in order to gauge the quality of their masterful encode.  Take note, "screenshots" meaning (frozen) frame grabs from the moving image, then micro-analyzed (zoomed, etc.).  So paano na kung moving image to moving image ang comparison.,

Ang possibleng makita kahit walang reference ay compression artifacts.

And yun crappy "BDRips" are encoded from encode (to save on filesize) and not from bluray source - kaya yun na nga ang quality.   Kung baga sa coconut, pangalawa or pangatlong piga ng gata ;)

totoo bang may super golden eye? yung matalas talaga mata? kaya malaman ng nanunuod kung 1080p bluray or 1080p encode? some even claim na alam nila mas maganda ang kinakalabasan na graphics sa certain video card brands compared sa certain video cards?

meron kasi guy sa ripley's believe it or not... na nafeature
kaya niya malaman kung anong model ng sasakyan by just hearing the sound of the door pag nagsasara...
i mean... thats super golden ears diba and sounds impossible...

Kung claim lang, tiyak na meron yon.  Madali lang naman mag-claim na may golden eye, ear, nose, tongue, touch.
 
5 senses pa lang yon.  Gusto mo 6th sense pa, sangkatutak na claim din.

Pero kung ang usapan ay papasa ba sila sa rigorous scientific testing, patay na.  Now that's a different story...  O0

It's more about bitrate.   I've seen 720p encodes that looked so much better than 1080p material because the former had an almost equal or higher bitrate.  There are 1080p encodes with only 1.5GB file size and the same title in a 720p encode but with 4.5GB file looked better.   Then again, the encoding also matters.  So far, I've noticed that H.264 encodes are the best for a given resolution.

kung gaano kagulo ang usapan sa source ganun din kagulo usapan sa screen
or
kung gaano pinagugulo ang usapan sa source ganun rin pinagugulo ang usapan sa screen ^-^

Nice graph. A little OT but this shows that the higher the resolution, the closer your viewing distance to the screen can be.

Whats the size of the monitor ? 40 inch?

Thank for the awesome photos.. hopefully somebody does this for 46 inch screens and larger so we can see at what size 1080p matters.  Sayang din ang space sa HD hehehe

That's a 50-inch plasma.  50V2.

Depends on the encoding group.  HiDt (~7900 kbps bitrate for that sample pic) and HDManiacs (~17500 kbps for that sample pic) as shown on the pics are arguably the best encoders right now.    That Bluray master source has about ~27500 kbps bitrate.

kung SD (standard definition) to HD (720P) lang ang media mo, okay na yan!  :)


pero kung 1080P ang media mo tapos sa 720P (or lower res) display mo ipapalabas, pangit ang magiging resulta.  ;)

Patingin?

I've got some good PDVD friends who use 42-inch 720p Plasmas and I dont hear anything negative about the quality of 1080p contents displayed on their screen.  In fact, what they told me was that for the most part, they simply couldn't tell the difference between a 720p and 1080p - and they like HiDt-level quality.  ;)

Web DL 1080p (actual size) - low bitrate, kinda soft, compression artifacts, cleaned film grains but even at 50 inch plasma, puede pa rin

Internally encoded 1080p (actual size)

Internally encoded 720 (fit to screen)

Blu-Ray Source

there are noticable differences with the 720p and the Bluray source but IMO this may only be noticed if its a still shot.  The color is almost identical and so is the detail.  maybe on a bigger screen (70" or larger maybe?) it will be more obvious but on a 42"...most probably not.

kung may noticable dapat sa buong movie mo mapansin kasi lahat nagbago bro, hindi naman selected frames lang ang binago diba?  ( IMAX filming is a different argument though).  Pero sabi nga nila, if thats what you believe and think you see then thats up to you.

dapat yata yung ibliblindtest is people who believe.. they can distinguish 720 vs 1080p... kasi ako admittedly talaga... hard to tell...

4k is coming ilan gig ba isang 4k movie? hehe does that mean.. kukulangin na ang bluray disk for a 4k movie? new format again???

napanood ko ko sa ces reviewers.. dahil wala pang media.. sony daw... pag bumili ka tv.. they will also give you a pc preloaded with 10 4k movies.. hehe $20k for the 84"

The "4K" bluray discs in CES are just 4K mastered 1080p Blurays. To follow pa ang 4K physical media and online distribution ng Sony. Well according to Sony ilang months na lang may online distribution na.

napanood ko ko sa ces reviewers.. dahil wala pang media.. sony daw... pag bumili ka tv.. they will also give you a pc preloaded with 10 4k movies.. hehe $20k for the 84"

Yup, yung HDD-based Ultra HD Player nila. :)

mukang hindi maganda ang look ng isang BD na sing laki ng LD
lossless content in a portable bag is more appealing  ^-^
madali lang naman dagdagan ng layer ang BD to accommodate large file size just like hard drive 500gb into 2tera which is 4x500gb :-\

Hehehe. If they can double the capacity of BD without inflating the cost substantially, pwede na yun. HEVC can do the rest. :)

I also think that noticeable ang difference between a 720p and the Blu-Ray source, especially in terms of color. But if the question is whether "enough" or not for a 42 inch TV...enough, maski 50 enough.  Masayang-masaya lang na nakikita kong umiilaw yung blue indication ng HD-audiostream sa AVR and that my media player actually plays like a real Blu-Ray player...hehehe

Kapag 3D, kitang-kita ang difference sa subs. 

Sabi ng Wife ko, pinakamalaking difference daw with the Blu-Ray source is if it's a Blu-Ray concert (other than the blue indication on the AVR).  Other PDVD friends told me the same thing about concerts.   The past 3 nights, I watched the old 80s Beverly Hills 1-3 Blurays all with DTS-HDMA with lots of 80s funky songs, and ang ganda nga ng tunog - that is, ang daming nuance na tunog sa mga surround speakers - and Eddie Murphy was exceptionally hilarious during those times.  hehehe

i think 4k would have to be at least 100gb per movie. hehe. i mean it's 4 times 1080p so ganun siguro expected file size. Kayang kaya pa ng blu ray medium. so far may RW na 128gb na blu ray. BDXL, if I recall correctly. I think they can still add more than just dual layers sa BD so pwede pa talaga mapalaki storage capacity
