    Hey BDAqua, if memory serves you said in one of the other posts you have OS X 10.8? Hows the Beta? Or is that not allowed to be talked about here?

  • BDAqua Level 10 Level 10 (120,910 points)

    X.8??? I plead the 5th.

    Hi again!:)

     

    Where can I get 7520p & 1080p Videos? Will try on a cpouple of G4s & my Quad G5...

     

    You can use MacTubes to download any available option on YouTube.  Most recent videos are available in 480, 720, or 1080p.  It might not be a bad idea to pick a single video so we can compare apples to apples (forgive me for that, I couldn't help myself).  I nominate Jedi Kittens Strike Back by FinalCutKing.  It's H.264/ACC/23.98FPS.  Or maybe we should find something with a full 30FPS?

    Thanks Swampus, good idea on the comparison too!

    That's a good idea, but the same monitor resolution for full screen playback will also be necessary.

    I know that my 23" monitor at 1920x1200 takes far different resources than my 17" at 1280x1024, and, of course, is not HD.

  • BDAqua Level 10 Level 10 (120,910 points)

    Well dang, then my eMacs won't help

  • japamac Level 7 Level 7 (24,390 points)

    Try it anyways.

    My 2.0 GHz QS won't play either the 1080p or 720p files for the Jedi kittens.....

  • BDAqua Level 10 Level 10 (120,910 points)

    OK, took a bit on Dialup, but...

     

    eMac/1.42GHz/2GB/64Mb ATI/10.4.11, of the four MacTubes download options...

     

    HD1080 was terrible but beter in half size in QT player

     

    HD wasn't much better.

     

    MP4 was flawless in even Full Scren & Fit to screen, didn't notice any pixilation or antything, seemed full rez.

     

    FLV played in VLC fine, but was likely doubled pixels & ugly to my poor eye!

     

    Maybe someone with better vision could pick out some defect that I can't see.

     

    I also quit Safari 4.1.3 for the tests that was using 24% CPU.

    I rip everything to MP4 and have no qualms with the quality.

    MP4 plays on all my machines, iPod, iPad and iPhones......

    The files don't eat up several GB each, either.

     

    I have had a hard time with this "HD this and HD that" mentality.

     

    Seems like, for the most part, it's just a way to eat up bandwidth, or, fill hard drives......

     

    Kind of like the "bloatware" that the majors are so fond of.....

     

    But, everyone keeps asking, what about "HD and PPC?"

     

    Well, for the most part (as we know), HD came after PPC, so it is NO wonder that PPC machines have difficulty with the large format stuff.

    Mine:

     

    Test machine:  MDD 2 x 7455B @ 1.58GHz, 2GB RAM, WD Black, FireGL

     

    Jedi Kittens @ 720p:

        

         Quicktime:  Played at full frame rate @ 65% CPU load (MenuMeter set to provide one number for both CPUs, so 100% means 100%).

     

         VLC (default settings):  No dropped frames @ 55 to 60% CPU load.

     

         VLC (settings mentioned upthread):  No dropped frames @ 40 to 45% CPU load.

     

    Jedi Kittens @ 1080p:

     

         Quicktime:  12 to 13 frames per second all of the way through @ 75% CPU load.  It was watchable for a short clip, but obviously choppy.  It was like watching 480P streaming with Flash--Not the way you would want to watch an actual movie.

     

         VLC:  Did not play with either setting.  The audio would play, but only two or three frames from the entire clip made it to the screen.  The statistics report was that only about 10% percent of the frames were dropped, but that's obviously incorrect.

     

    I also tried both clips on a nearly identical machine with a Radeon 9800.  I was unable to detect any difference between the two.

    Really, I agree.  Although I admit that there is a very small number of things that I want in full HD, I prefer MP4 for almost everything, and for the same reasons as you.  More than anything, I think this has just become a game to me.  Do you ever want to try something just to see what happens?  I've read your website and I know that you do. 

  • Swampus Level 2 Level 2 (180 points)

    It's probably also worth mentioning that both of the machines that I used are normally multi-display setups, but it made no difference when the additional display was disconnected.  The video cards performed just as well when their resources were divided between two displays as they did when focused on one.  I interpret this to mean that either video card is well more than enough here, as would, I suspect, be any Core Image capable card.  Does anyone find fault with my reasoning here?

  • japamac Level 7 Level 7 (24,390 points)

    Guilty as charged!

    The GPU that also supports CI, yes, I agree.

    VRAM over 128 MB is also a must for the display buffer.

     

    Really, HD is so CPU bound in OS X it's not funny.

    Estimates put CPU load at 5x that of a MS OS running the same video.

    Heavy Hollywood CG content; Yes. National Geo and Discovery nature video; Yes.

    It always comes back to CPU doesn't it?  I've got it, though.  Altivec to the rescue.  I'm watching me some Jedi Kittens in full HD on my MDD with no dropped frames.  Now to encode some things that I really want.

     

    I finally got around to purchasing CorePlayer tonight.  I've seen people tout its Altivec prowess for long time, but I've regretted purchasing things without a demo or free trial in the past.  No regrets this time, Japamac.  I saw a promo code posted on another site (MBHD20) and went for it.  Got it for $16.  It's just jaw-dropping to see what good Altivec code can do.  Have you ever tried this? 

     

    At first, it pushed my CPU to 100%.  Then I disabled "AVC deblocking filter" in the settings menu.  That dropped my CPU load down to 70% and the quality is still outstanding.  Wow.
