I just found out that QuickTime 7 Pro is not a 64-bit application.<br>What is the value of having a 64-bit operating system and a 64-bit computer if Apple isn't going to make their applications 64-bit?<br>I was looking forward to doing some video editing with QuickTime 7 Pro.<br>But no, I am stuck with a yesterday's 32-bit application. <br><br>On Apple's web site they have 16 pages dedicated to "Tiger's" support of 64-bit applications.<br>16 pages explaining to developers the benefits of creating 64-bit applications.<br>Why should anyone else create 64-bit applications if Apple won't?<br><br><br><br><br><br>
Why do you feel QT Pro should be 64-bit?<br><br>64-bit will not make it faster, so what exactly do you expect being 64-bit to give you? What are you doing in QT Pro that would needs to be 64-bit?<br><br>
Data-intensive tasks such as video encoding, gaming, CAD will have speed increases with 64-bit computing.<br><br>I use QuickTime Pro for DVD editing. I sometimes use lossless DV codecs<br>I use Final Cut Pro HD and Combustion as well. <br>Some of my QT movies are over 15 GB in size.<br><br>
Yes, but QT in this case, is only used for the encoding, which shouldn't matter that much. Operations in Combustion and FC, would call MacOS X's built-in math libraries which are 64 bit. And actually, your lossless DV codec may be able to do that too.<br><br>
Encoding is exactly what 64-bit computing is supposed to be good for.<br>There are many times that I am getting pageouts while encoding.<br>I have a dp G5 with 2.5 GB of memory and I am getting pageouts?<br>I have to believe that a 64-bit QuickTime application would be a vast improvement.<br><br>
You have 2.5GB of RAM. 2.5GB of RAM can be addressed well within 32 bits of address space. 32-bit address space can address up to 4GB.<br><br>You are getting pageouts because your application needs more than 2.5GB of RAM. You mentioned you have 15GB video files. That's the reason for the pageouts - it has nothing to do with not being 64-bit.<br><br><br>
I'm no programmer, but here's my perception of the whole 64-bit thing. <br><br>I think the marketing has gotten ahead of the actual, real-world expectations of what 64-bit computing can accomplish. <br><br>It reminds me of when we were all toiling away in OS 8 and 9, and the hype for X was incredible....it was going to unlock the heretofore hidden performance of the PowerPC! Didn't happen. <br><br><br><br>
Yes, one of the biggest benefits of 64-bit computing is the potential to add tons of memory.<br>I also agree that for what I am doing I need more memory.<br>But I still think and will continue to do so until I see something to the contrary that QuickTime 7 Pro would be faster as a 64-bit application with the computer set-up that I have now.<br>At this time it takes around 3 minutes for DV editing to eat up my memory and slow down my computer.<br>My contention is that with QuickTime 7 Pro as a 64-bit program, the encoding would be faster and it would take longer for my memory to evaporate so to speak.<br>Your contention is and correctly so that my application (Quicktime) needs more than 2.5 GB of RAM. <br>But that same statement also tells that QuickTime can be a data-intensive application and therefore should be a prime-time candidate for 64-bits.<br><br>If being able to add more memory to a 64-bit computer than to a 32-bit computer was the raison d'etre for a 64-bit computer and operating system then what would be need for 64-bit applications? <br><br>Here is a quote from Tom Huntington, corporate communications manage at DivX, "Video encoding will also improve in a 64-bit world, the company's DivX codec compresses DVD-quality video up to ten times more than the MPEG2 standard, making it easier to transmit over the Internet.<br>A 64-bit processor will improve both the encoding and decoding of video. Better still, when you view a video file on a 64-bit desktop, you'll see "a noticeable difference in speed resulting in more frames per second and a more film-like playback."<br><br><br><br>
Here is an interesting article regarding 32-bit vs 64-bit computing.<br>LINKY<br>Note that the computer is only using 1.24 GB of memory for the benchmarks.<br>I realize this is a PC system but it illustrates 64-bit vs 32-bit applications with a 64-bit processor and a 64-bit operating system.<br>Interesting quote, "A decent, almost 20% boost here for the 64-bit version of the Div-X encoder. Another mathematically intensive operation that benefits from the extra registers and headroom of 64-bit mode. DivX compresses video and audio data and is based on the MPEG-4 compression standard."<br><br>If Div-X encoder can benefit from a 64-bit computing system with only 1.24 GB or memory, why not QuickTime 7 Pro?<br><br><br><br>
