Have 7 hours of SD content to burn to Blu-Ray...

Have 7 hours of SD content to burn to Blu-Ray it says it takes up 20 gigabytes of space in FCPX, but when I burn it only 2 hours of video ends up on the Blu-Ray. What is going on?

Can you screen shot your export settings? It sounds like something's happening during the transcode, and you're ending up with a much higher bitrate than you're starting with.

Are you wanting a playable BD disc (to play in a Blu ray player) or are you simply archiving this video on a BD disc?

I want a playable Blu-Ray disc.

Take a look at your rendering settings. For example, the bit-rate may be set for HD, on the order of 10-15 Mbps . SD would be much less than that - maybe 1-1.5 Mbps or less. Look at the audio settings, too.

What dvd drive are you using to burn the disc?

Well, what about those settings you got asked about?

Have you considered getting Toast DVD, then the Bluray plugin ? Works flawlessly for compiling video projects to discs.

Could there be a hard 2 hour limit for discs? I know there was for DVDs.

Also (but not related) you have a mismatch between frame rates of your source and your project.

There is NO limit on the length of content that can be put onto a DVD/Blu-Ray disc, you are only limited by the size of the disc & thus the data rate of your video. Now some software i.e. FCP or iMovie may impose limits onto how much content can be burned onto a single disc. I have personally put 3-4 hours onto a DVD (now this was just talking heads & not the best quality) but I am using more professional tools i.e. DVD Studio Pro & Adobe Encore. I'm pretty sure you could easily put 7-8 hours of SD content onto Blu-Ray using Encore.

I don't think I ran into a two hour limit. I regularly put 3-4 hours of SD material compressed to 4.5GB onto DVDs. They looked pretty good.

Now there were some free demo software around that had limits.

That's the limits I was referring to. I know iMovie had a hard limit of 2 hours, I'm not sure if FCP X does. Since Apple put DVD Studio Pro out to pasture and generally deprecated DVD burning, I thought it worth mentioning that.

Does the BluRay disc look full with the two hours of footage on it?
(Disclaimer: I have never burned a BluRay disc, just DVDs, so I don't know if the burned region of a BD-R looks different to the unburned region)

I don't think FCP directly had a hard two hour limit, but it could have. You couldn't tinker enough with the settings to squeeze more video in like one could with compressor. So the work around was export master files from FCP and then use compressor to make the DVD image or suitable DVD clips that an authoring program could assemble into a DVD that would play as long as you like... maybe not at the best quality.
