Burn blu ray from original .mov files stored on external hard drive question

Hi, I have successfully edited long projects and burned DVDs from my high resolution *.mov files stored on my usb external hard drive.  I now want to attempt burning these projects to blu ray with my built in LG blu ray burner.  Am I asking for trouble with the data transfer rate being too slow from the WD Elements external drive?  I really don't want to transfer the original files to my hard drive if I can avoid it.  I do have one blu ray rewritable disc available.  Thanks!

Hi

The data transfer speed from the external drive should not be an issue on the assumption that there is not another external hard connected and being accessed at the same time.

The burn process involves the data being loaded into a buffer so that the writer can burn complete blocks of data.  When the buffer content level drops below a specific level then the burner 'waits' for the buffer to refill before continuing.

The main issue will be that should the USB ports go into power save mode then the burn could be aborted. In theory this should not happen when the drive is being repeatedly accessed for data, however in paractice this can happen.

On my PC I turn off the power saving mode for the USB ports - for my laptop I leave it on.

Hi

In addition to what John says, I would think that if you did not have any problems editing (and rendering to DVD which probably created the disc image to the default C:\ drive folder) then you should not have any problem creating an HD disc providing the disc image is created on your C:\ drive.

To be safe though, if you only have one disc, I would start the disc creation step without the disc in the burner so that it creates the HD image in the default folder where you can then review it, before burning it via the Magix or some other burn program.
