PM dual1.8GHz - Full HD Video?

LMAO! Yeah we got too into our heated discussion that we completely forgot about the important stuff =D

So, you can play 1080p on your dual 1.8GHz without dropping any frames? What are you using for your player and what is your CPU load if you don't mind my asking? I'm not sure if it's going to be possible on my G4 except maybe with CorePlayer.

Ok so 1080p? Not so bad it drops some frames...CPU load is 180%—200% usually barely plays...I also used Xslimmer to give my whole system a good speed boost because it strips away all languages other than English and all code but the native 32 bit or 64 bit PPC. (64 Bit for G5 and 32 for G4) and I use VLC and CorePlayer.

:-) Indeed. RAM is probably the first thing that should be upgraded here.

Agreed. That would probably make the biggest difference here anyway. lol

He can likely see how much RAM has to do with it, & secondly how much HDD speed has a play by using Activity Monitor>Memory tab, & see how many Pageouts there are, each one requiring moving Memory to VM/Disk, & VM back to RAM Memory again.

Not everything will speed up the Video playback, there are limits to the CPU, GPU, & Bus speed, but every area can slow it down.

Im unsure of that BDAqua as I dont have the machine with me (I gave it to my significant other) but with 720p it plays wonderfully—That being said the data being played is on the main HDD itself—and I have 2 2TB WD Blacks in it. But 1080p skips quite a bit. I dont know how much speed increase it would have if I put a faster yet HDD in it (SSD, or VelociRaptor)

And if I had a faster GPU. Its very possible...oh and btw..the FX 5200 can display the transucent menubar...I found a work-around for that finally too. Transbar. http://petermacwhinnie.com/transbar.php

I mis-spoke, I should have said maybe diminishing returns, A faster HDD or SSD will take pressure off the VM slowdown of the OS & of course if you're playing it from the Drive, some minimalal difference, but it still boils down to rge weakest link. 😉

Not to add to this confusion, but my G4 MDD with its current specs can play 720p videos with minumum frame drop when downloaded to my internal or external drives. 720p streaming over WiFi has some noticeable frame drop, but still is completely watchable. If they are YouTube or other video sites with 720p, I usually download them first, then play. They playback with very slight frame drop or video delay.

720p video do run on my G4. Should run even better on G5 with better specs than my Mac, you would think?

1080p video is just not possible or going to happen on my G4. Can't get video to run at all or the frame drop is soooo bad that it's completely useless and unwatchable. Most of the time with 1080p, I get audio with a blank, black screen for most or all of the video playback.

I am in the process of deciding whether to purchase a dual 2.3 Ghz G5 Mac with 12GBs of RAM with a 256 MB VRAM Geforce 6600 video card. Do you think that Mac would, at least process/playback 720p without any issues? I basically, looking for a newer PowerMac that will better handle, at least 720p video playback without issues.

Any chance of getting 1080p playback on a Mac G5 with those specs?

I am, basucally, looking for just good to better 720p video playback, anyways.

Also, are the dual 2.3 G5's good, solid Macs?

Will be doing this very soon.

Hi again!:)

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

All that being said, if possible I'd shoot for a Quad/Late 2005, only G5 that comes close to some IntelMacs...

To give you a rough idea of the processing power...

Mac Pro "Twelve Core" 2.66 (2010/Westmere)... Geekbench: 20294/22605

He has a dual, though. I can play 720p just fine on my dual 1.5 GHz G4 with either VLC or Quicktime/Perian.

That may be. I am simply citing what is based on original HD playback recommendations for QuickTime, OS X and a G5.

The DP 1.8 GHz machine wasn't rated for 24 fps at over 480p.

And I know that 1080p ain't happening....

It wouldn't work (without great effort and still frame rates insufficient) on a DP 2.0 GHz G5 with WD Raptor boot drive, 4 GB RAM and Geforce 6800 GT.....

30 fps is needed to convince the brain that the eyes are seeing smooth video.

Don't think QT is DP aware, either.

Besides, in this case, running HD simply converted to .mov is a bit different.

Agreed, different encoding and different playback likely will improve the playback, but "full HD" is an impossibility on that machine.

Where can I get 7520p & 1080p Videos?

Geez, BD, I don't think even my 6 core i7 with Crossfire HD 6870's will play 7520p.......😮

Yeah my G5 struggles with 1080p but then again seriously HD is HD. 720p or 1080p can you really tell the difference? If 720p plays great and its still HD, is that quality seriously so bad that you GOTTA HAVE 1080p? Just my 2¢ lol And why keep such a load on your system? My MacBook (Mid 2010 Unibody) Plays 1080p ok though. (2.4GHz Intel Core 2 Duo, 8GB DDR3 1067MHz, 750GB 7200RPM WD Scorpio Black HDD, OS X 10.7.3 Lion (heheh Mountain Lion is coming soon!), 256MB NVIDIA GeForce 320M)
