I read the camera is just VGA (640x480). My niece is on a MacBook, so I suppose her screen resolution is at least four times that.

- ars 16y agoHe's trying to say you won't be able to upload such a high resolution over your internet connection, so it doesn't matter. Even 640x480 is tough to stream real time from most people's home internet connection. You also have to compress it real time, which may not be possible at a higher resolution.
- Tichy 16y agoWhy did Apple put HD webcams into their new MacBooks, then? They seem to be more optimistic about the resolution that can be transmitted.
- ars 16y agoYou can use the camera to record, and then upload non-realtime. Like youtube for example.
- ars 16y agoYou can use the camera to record (and compress), and then upload non-realtime. Like youtube for example. A small tablet probably doesn't have the CPU power to compress an HD stream, but a laptop should.
- Tichy 16y agoThe Apple specs say specifically "FaceTime HD camera", which seems to suggest they believe transmission of HD chat videos is possible http://www.apple.com/macbookpro/specs.html http://www.apple.com/macbookpro/specs.html Also, who says I prefer framerates over picture quality? Perhaps a reduced framerate is the better tradeoff in exchange for high definition images.
- ars 16y agoYou would need an upload speed of around 5Mbit/s to upload HD video (720p). Less for lower quality of course, but then why are you doing HD in the first place? It's doable, but not realistic for most people. You also need a monster CPU to compress video that much in realtime. With a slower CPU you'd get worse compression and need a faster connection (or lower quality). Reducing framerate doesn't help as much as reducing resolution because little changes between frames, so there anyway isn't much to upload. (You either upload a lot infrequently, or a little frequently. It doesn't matter a ton. You get some benefit, but not much.)
- Tichy 16y agoWhy the downvotes? I want my mum to chat with my niece. Mum would have an iPad, niece a MacBook. Mum should look good on the MacBook. Also, Facetime has been a major element of recent Apple ads.
