quick blu-ray question
Hey guys,
did a quick test of burning High Def footage onto a STANDARD DVD using FCP and played on my blu-ray player. I”M aware the actual transfer speed is more like 13-15 mbs and done with a red laser vs. true blu-ray which is closer to 30 mbs and uses a blue laser. However, I must admit for my clients, the quality of the Blu-ray ‘hybrid’ I made with a mac superdrive and a regular DVD work just fine for me.
that being said, Can I use the same workflow and burn a longer program on a regular blu-ray disc (accepting the lower transfer speed), or can you not use a mac superdrive to burn onto actual blu-ray media?
Also, has anyone been able to determine (using FCP BLu-ray presets) how much media I can put on a standard BLu-Ray?
thanks!
Rick

I do the red laser burn of AVCHD quite often. have you seen the Ken Stone tutorial?
https://www.kenstone.net/fcp_homepage/burn_br_mac_superdrive_stone.html
Bottom paragraph has a succinct summary of info.
Apples built in DVD drive is NOT a BD player. It’s Red Laser only. Apple does not sell or support a BD drive, although you can certainly install a 3rd party unit. You could try and get a Pioneer (or comparable) BD burner, and use a 3rd party piece of software (like Toast) to burn a true BD disc.
If I recall correctly, baseline for most houses is 2 hours of MPEG2 on a 4.7GB BD (typically 20-30Mb/s), and h.264 is approximately 2x that. (h.264 offers a 50% space savings compared to h.264 with the same apparent visual quality)
Data rate varies wildly with who ever the “Compressionist” (*you*) is. I normally hover around 25Mb/s.

I think he was asking if you could do this AVCHD format onto a bluray disc and get the benefit of the extra space/time. Basically doubling the normal length of a blu-ray disc.
And fwiw, I do the ken stone method, except I don’t burn a disc, nor make any sort of disc image. I just have it create the file. Then I take the file over to toast and create blu-ray (avchd) with much more menu choices than the cruddy apple share ones.
