Recommended Hardware Configurations for H.264 High Definition (HD) Playback

To play high definition video, a large amount of data must be processed by your computer. A powerful system will deliver the best playback experience.

For 1280x720 (720p) video at 24-30 frames per second:

    * 1.8 GHz PowerMac G5 or faster Macintosh computer

    * At least 256 MB of RAM

    * 64 MB or greater video card

For 1920x1080 (1080p) video at 24-30 frames per second:

    * Dual 2.0 GHz PowerMac G5 or faster Macintosh computer

    * At least 512 MB of RAM

    * 128 MB or greater video card

I'll test your file out to see how it fares on my machine... but it seems that G4 people are left in the dark for H.264 HD content in QuickTime 7. :(

Edit: I just watched the BBC one... boy, does this suck or what!? I had tried playing HDV content through VLC before and had the same results, so I'm not surprised at all. Too bad, I love HD!

This is worrying, I really want a powerbook, but it seem's they are just not good enough to handle many thing's. I mean come on, VIDEO.

10.3.9 + QT7 = 12FPS at normal size.

I love this guy's "I mean come on, VIDEO" comment... as apparently the only type of video anyone will ever use again will be HD :rolleyes: By the time HD hits mainstream, I have no doubt every computer Apple makes will have at least 1 G5 core in it.

where did u get "normal" contents in H264? I think trailers on apple.com are still in H.263 or other formats, no?

Well no, on the quicktime page, you'll have a link in the top-right corner to HD videos. There you'll find some trailers in H264 codec, "normal" (1228x544) and for some of them even the 1080i version.....

The 720p trailers (1280x720) run fine on my PowerBook. There are a few dropped frames according to QuickTime but I didn't really notice them. The "Batman Begins" trailer in 720p is awesome. :D

I highly doubt it will run 1080i at more than 5fps though. Besides, why would I want to run 1920x1080 pixels of video on a 1280x854 screen? :laugh:

My 12" PowerBook does 720p H.264 video quite well. It's the 1080p version that my PowerBook completely crawls on. This doesn't mean H.264 is useless on PowerBooks. It just means HD video encoded in H.264 above 720p doesn't fare too well.

Well no, on the quicktime page, you'll have a link in the top-right corner to HD videos. There you'll find some trailers in H264 codec, "normal" (1228x544) and for some of them even the 1080i version.....

What I meant was all content on www.apple.com/trailer is still in h.263 format except those hd trailers are in h.264 format

    • First exciting thing to come to Windows in a long time ! This is the kind of things they should focus on, instead of cramming as much AI as they can in everything.
    • New AMD graphics driver fixes install issues and FSR 4.1 crashes on RX 7000 GPUs by Taras Buria AMD is rolling out yet another graphics driver. Version 26.6.4 is now available for download, bringing two important fixes. One is for those still using Windows 10 and having trouble installing driver 26.6.2. In fact, this patch is coming from the recently released hotfix, so it is not new if you are already running version 26.6.3. The second fix is for RX 7000 owners. AMD recently brought FSR 4.1 support to the previous-gen graphics cards, but there was a bug with certain games crashing when using FSR 4.1. I experienced this issue with Forza Horizon 6, so today's driver should take care of that. Here is the official changelog: Intermittent install issue seen when installing AMD Software: Adrenalin Edition 26.6.2 on Windows® 10 systems for Radeon™ RX 7000 series and above graphics products. Intermittent application crash may be observed in some games with AMD FSR Upscaling 4.1 enabled on Radeon™ RX 7000 series graphics products. Known issues include the following: Intermittent application crash or driver timeout may be observed while playing Battlefield™ 6 on AMD Ryzen AI 9 HX 370. AMD is actively working on a resolution with the developer to be released as soon as possible. Texture flickering or corruption may appear while playing Battlefield™ 6 with AMD Record and Stream on some AMD graphics products. AMD FSR Upscaling and AMD FSR Frame Generation may show as inactive in AMD Software: Adrenalin Edition while playing Battlefield™ 6 when enabled on Radeon™ RX 9000 series graphics products. Failure to install may be observed while installing AI Bundle components in some regions with limited access to HuggingFace and GitHub. Model flickering or rendering failure may be observed in Maxon Cinema 4D and Blender on Radeon™ RX 7000 series and above graphics products. Users experiencing this issue are recommended to install AMD Software: Adrenalin Edition 26.3.1. Intermittent application crash may be observed on some models while running Blender on Radeon™ RX 7000 series and above graphics products. Users experiencing this issue are recommended to install AMD Software: Adrenalin Edition 26.3.1. You can download the AMD Radeon driver 26.6.4 from the official website here. Full release notes are available on the same page.
    • Amazon may use OpenAI and Nova models after Anthropic reportedly raises costs by Karthik Mudaliar Amazon is reportedly considering to use OpenAI models and even its own Nova family of AI models after Anthropic raised the cost of using Claude inside Amazon services. According to a report from The Information, Amazon is weighing its options to reduce costs under a new arrangement with Anthropic. But back in April, Amazon said it would invest $5 billion more in Anthropic, with the possibility of adding up to another $20 billion if certain commercial milestones are met. That investment actually came on top of another $8 billion Amazon had already put into the Claude maker. Anthropic, meanwhile, committed to spend more than $100 billion over 10 years on AWS technologies, including Amazon’s Trainium chips. Amazon isn't just a customer of Anthropic but also one of the most important backers and cloud partners. This is why it makes it interesting that Amazon is considering other alternatives to handle its internal workloads. Although Amazon has been building its own options for a while now. Its Nova family of AI models was announced in late 2024 for Amazon Bedrock, with models aimed at text, image, and video tasks. Amazon pitched the model around cost and latency at that time. With that said, OpenAI has also become a more realistic option recently for AWS customers as well as for Amazon itself. Earlier this year, OpenAI brought its latest models and Codex coding agent to Amazon Bedrock, after changes to its previously more restrictive Microsoft cloud arrangement. This allowed AWS to serve even those customers who wanted other alternatives from Claude, without having to move workloads out of Amazon's cloud. Evaluating alternatives could also be due to commercial pressure and not necessarily a sign of a damaged partnership between Amazon and Anthropic. Whether or not Amazon is actually considering switching entirely to OpenAI's models or its own Nova models remains unknown at this moment.
    • Samsung introduces new AI classroom tools and interactive displays at ISTELive 2026 by Fiza Ali Samsung has announced several new education-focused software features and interactive displays for schools during ISTELive 2026, taking place in Orlando, Florida, from 28 June to 1 July. The focus of these updates is on making shared classroom displays easier to use for teachers while giving IT administrators more control over managing devices. One of the key additions is the Samsung Account Management Solution (AMS). In many schools, multiple teachers share the same interactive display throughout the day, which means signing in and setting everything up can become repetitive. With AMS, teachers can log in by scanning a QR code or tapping an NFC-enabled ID card. Once signed in, their personalised workspace, including wallpapers, bookmarks, app shortcuts, and files, can be instantly accessed through Home Personalisation. Samsung has also included a screen lock feature, allowing teachers to lock the display if they need to step away briefly. Furthermore, the company is also updating its Education Portal with new tools designed for school IT administrators. The portal will allow IT administrators to register teachers, enrol devices, and manage user access from a central dashboard. Administrators can also link NFC cards to teacher accounts, making sign-ins quicker across shared displays. Another addition is a Tags feature that lets schools organise displays by building or classroom. Those tags can also be used to send emergency notifications to selected Samsung Interactive Displays through compatible platforms such as InformaCast and Raptor. Moreover, the tech giant's AI Assistant is gaining several new features aimed at supporting everyday classroom tasks such as lesson planning and classroom engagement. One of the features is Circle to Search, which lets teachers circle text or images on the display to quickly find related information, videos, or web results without interrupting the lesson. The content can then be brought into Samsung Whiteboard. Another feature, Live Transcript, converts spoken lessons into real-time captions, which could be useful for students with hearing impairments or those in multilingual classrooms. The AI Assistant also introduces AI Summary and AI Quiz. The summary tool creates summaries of recorded lessons, while AI Quiz generates questions based on lesson content so teachers can quickly check how well students are following along. Teachers signed in through Samsung AMS can also return to their previous AI-generated lesson materials without logging in again. Alongside the software updates, Samsung has expanded its Android-based Interactive Display range with three new models: the WAF-S, WAFX-PS, and WAHX-M. The WAF-S and WAFX-PS ship with Android 16, bringing updates to security, accessibility, and overall usability while maintaining compatibility with Google's education services including Google Classroom and Google Drive through EDLA certification. Meanwhile, the new WAHX-M is the biggest addition to the lineup, introducing a 98-inch display for larger spaces such as lecture halls and conference rooms. It will also be available in 65-inch, 75-inch and 86-inch sizes. Samsung says the WAHX-M further includes on-device AI features such as voice commands, text-to-speech, and an AI calculator, alongside support for Samsung AMS and AI Assistant. Samsung AI Assistant has been available since April, while Samsung AMS and the updated Education Portal will begin rolling out in July.
    • It's been $24 (single) or $89 (4-pack) for many days on both Amazon and Walmart as far as I know. That isn't a big discount. If these end up like the 1st gen, the 4-pack will routinely get down around $80, give or take a dollar. I think they have even hit $69 at times.
