Toast Downscaling My 1080p Movies To 720p

Question

Hi all.

 

I have run into a problem using Toast and burning HD movies.

 

I create HD videos on a regular basis and have recently started using an External Blue-Ray burner to burn these to disk for use on other blue-ray players.

 

When I create the movie in iMovie it will happily play in 1080p as will any other application on my mac after the movie has been exported.

 

As soon as i burn this to Blue-Ray the movie is down scaled to 720p, I cannot work out how to get it to burn in 1080p.

 

Any advise would be greatly appreciated.

 

David

Well, it can be done (and it can't be done).

 

To put it simply, the only 1080p standard supported by Blu-ray or AVCHD is 1080p24 (or 23.98). If you're taking something out of iMovie then you're working with something that may in fact be 1080p but it's 1080p30(or 29.97). So you cannot encode that footage, with anything, at 1080p for playback on blu-ray; blu-ray doesn't support that standard.

 

That being said, if you want 1080p blu-rays I've come up with a workflow.

This is specifically for doing 1080p AVCHD using Adobe Encore and Final Cut Express. To do the same thing in Toast (and it can be done) you have to find some other program to do your encoding for you, because the Toast encoder will not encode at 24 frames per second, but Toast will multiplex properly encoded transport streams that are 24 frames per second, but you have to get your footage down to 24 frames per second.

 

What's interesting is Toast should be encoding these at 1080i actually, not 720p. Is your play set-up to only display progressive output?
