Mac Pro :: Struggling To Play HD Video?
Mar 10, 2010
I just finished editing an HD photo montage and decided to export it as an H.264 quicktime file. I was aiming for a high bitrate since the pictures are in motion, and I ended up with a 1080p30 file averaging roughly 20-40 mbps. I know this is extremely high, but I wanted a blu-ray quality encode.
Playback on my TV via PS3 looks great, but for whatever reason, this file is bringing my 8 Core, 10 gig RAM Mac Pro to its knees. Opening the file in quicktime results in horrible stuttering playback, while VLC will start playing smoothly at first and then crash, citing "computer too slow" as a possibility for the error.
I'm having a hard time believing that this machine can't playback a high bit rate H.264 file. Any ideas? Oddly enough, the activity monitor is showing only moderate usage of system resources during playback.

I listen to and watch a lot of podcasts. Quite often, after I am done listening to a Audio Podcast I will watch a video podcast. Some times it gets stuck and won't play the video but plays audio fine. Anyone else have this problem?

I'm giving an old Dual G4 Power Mac to my father for Christmas. I would like him to see the 10.5 multi-lingual welcome video [URL] when he boots the computer for the first time. What can I do before I shutdown the computer for the last time before I give it to him so it plays the video on the next boot?
Ideally I'd like for the OS to show the video full screen like it does after an install, and then show the login window (or in his case, automatically log in). I'd prefer not to add the video to his account's login items

When I try to watch any CNN video, nothing plays. WHen I click on the play/pause indicator I get "02:37" in large type across the video area. The same thing happens to any video. It happens in Safari, Firefox, and in IE in virtual Windows through VMWare. THe same thing happened earlier in the year, then it seemed to resolve itself for a few months but now the problem is back. NOthing I try seems to help. I am using Mac Pro (early 2008) OS X 10.6.4

Apologies for my naivet� but I've recently switched to MacBook Air. I would very much like to watch video clips from my local newspaper but when I click to watch I'm told I don't have the plug-in/MIME. It leads me to a page for download but all that does is give me a document in Text Edit. It appears as hieroglyphics/gobbledygook. Is anyone able to tell me what I should do to get this really wonderful little machine to play Windows style video clips?

I am trying to view a DVD (TS file) on my PowerBook G4 - I know the computer works because I just watched others, but I have two DVDs that won't play - I am just getting a black screen with yellow and pink frames that float in the screen when I click play.

Safari on my wife's iMac does not display video. Our home page has a video imbeded that plays just fine on my Mac Pro and we are both using the latest OS, 10.7.3, and the latest version of Safari, 5.1.3. She also has Firefox installed and it plays the video just fine. When I check her installed plug-ins, she has the QuickTime Plug-in 7.7.1, just as I do. Why does video show up in my setup, but not on my wife's iMac when we are using the same software. Do I need to re-install Safari?

I am not sure why but my computer froze and I had to re-boot it. Since then I cannot run any video on you tube. I get a message that says "this video is currently unavailable". Does not matter what video it is. BTW, My MacBook works fine so I know it is not internet related.

I have Office for Mac 2004 on a MBP intel core2duo. OSX 10.5.8
I can't get a PP that was made on a PC to play the video when in the slide show mode. I can view video fine in slide view, outline view, and normal view, but when I play the slide show all I get is the audio and a still frame.

I have transferred some files from my a JVC Everio camcorder (full hd). The file type is .TOD, but I can play them when changed to .AVI. Anyway, the problem is - I can only play them without lag in windows media player. What is the problem? Am I missing a codec or something?

Once in a while, a flv (flash) video I have download from the internet from sites like YouTube (using CosmoPod) will not play video when opened in QuickTime. The space for the video is there in the QuickTime window, but it is all black. Audio plays fine. This only happens for some flv files and I can open them all just fine with VLC and Adobe Media Player. Any idea why this is and/or how I can fix it?

Ive been having problems playing .avi and mp4 files. I try to open them in Quicktime, Realplayer and VLC. Every time the program closes unexpectedly after a few seconds without playing anything. VLC does the best by at least playing some sound for 5-10 seconds before closing. These files used to work fine only a matter of a week ago. I tried re-installing all 3 programs but with no luck, I tried re-installing codecs like perion, divx and xvid with no success. The only files that continue to play fine are mpg, flv and wmv. I have no idea whats going on.

I have been having problems playing .avi files with my computer. At first it was running 10.6 and after being upgraded to 10.7 the problem is still there.
I have been trying to install different codecs -- Perian(1.2.2 & 1.2.3 and uninstalled DviX first), flip4Mac, etc, but everytime i try to play an avi file with quicktime player X, it says that quicktime player can not open the file 'A required codec is not available'.
I have also tried to open the file with Quick Player 7 and VLC, the strange thing is that the video 'plays' (the sliding bar is moving), but i see no video in the application window -- it was just all black.

I have a 2011 Mac Mini running the latest version of Mac OS-X and iTunes, output to a Samsung D6530 Television and for some reason I can't seem to play HD movie or TV show content purchased through iTunes. 99% of the time I don't get any error message at all, just a scrambled signa (sound is fine)l however, the one time an error message did appear it suggested the TV did not support HDCP (High Def Content Protection). Looking at the documentation that came with the TV it does support HDCP so I can't figure out why it doesn't work.
Info:Mac mini (Mid 2011), Mac OS X (10.7.3), iTunes 10.6.1 (7)
