View Full Version : Bluray discs glitches

I just finished burning a Bluray disc using Toast Titanium 10.

I exported (using FCP) the videos as Apple ProRes 422 (HQ), 1920x1080, 24 fps

And I stuck the disc in my PS3 and the video is extremely glitchy!

Did I export it wrong?! What is the best way to export for Bluray?

Hi Megan,

I use the same setup as you. I haven't tried one of our blurays in a PS3 (I sure hope they work!).

Here are the settings that I use for the video end of things.

Compressor:
QUALITY
Mode: Two Pass VBR Best
Average bitrate: 15 Mbps
Maximum bitrate: 20 Mbps
Motion estimation: Best


Toast:
ENCODING: Custom
Video Format: MPEG-2
Average Bit Rate: 15 Mbps
Maximum Bit Rate: 20 Mbps
Motion Estimation: Best
Reencoding: Never
Field Dominance: Automatic
Aspect Ratio: Automatic


Those seemed to be the most important settings in order to get compressor's files to go to Toast without having Toast recompress them.

Maybe someone with a PS3 will be able to contribute more info.

Best wishes

Why are you using MPEG2 for BluRay? That's the LAST option I'd choose.

Interesting question!
I don't know very much about formats, but I found those settings online from a user who'd managed to make FCP and Toast work together without having to have Toast re-encode everything. What format(s) would you recommend for Blu-ray?

Thanks

Usually, the speed of encode..
Unless you're trying to get out over 2:00 of video onto BD, then there's no reason to take advantage of h.264's compression scheme...

@Megan

You'll need to be more specific then, "Glitchy playback"...
Is it only on YOUR PS3? How does it playback on your timeline.

I suspect that it would be the 24P framerate.
Perhaps there's a pulldown required?

Glitchy - as in there's a flicker. Like the frame rate is way off. But I exported from FCP at 24fps, with the setting that I stated in my first post.

There is over 3 hours of video though, so what does mpeg 2 vs. h.264 have to do with over 2 hours of video?

And the most confusing part for me is that I burned a bluray a month ago, as far as I know, the exact same way as I did this time, and it worked perfectly fine, in my PS3.

(also, I don't really see why a PS3 would be any different then a regular bluray player.)

They are both compression schemes, but the h.264 allows for the same visual fidelity as Mpeg2, but at lower bitrates....
Meaning that you can get lots more playback time with the same quality as Mpeg2..
The drawback, is that it requires more horsepower to encode, and decode...

As far as your glitchy playback, it could be anything from a bad disk, to a bad burn, to a faulty burner, to a bad PS3 station...
If you're 100% positive that you've done this the same way as before, then these will be the factors..

Everything else is a guess..
I'd start off by playing it in another player. Then work down the line of possibilities...

good luck!!!

Thanks Peter.
Good to know!
