Compressor Bitrate for HD Content?

[Jason Brown]

Is this blu ray or sd DVD?

[Amber Miller]

It’s Not Blu Ray. I guess that brings up a good point. Does it have to be blu ray?

[Jason Brown]

Standard Def DVD specification has a max resolution of 720×480 and can be 4×3 or anamorphic 16×9 and has a maximum bit-rate limitation of 9Mbps (although that is peak and you never encode that high)

Blu-Ray (I’m not an expert on this) has a maximum frame size of 1920×1080 and I believe can support 60p. Bit rate limitations are upwards of 35-40Mbps.

We may be slightly on different pages.

In Compressors Inspector encoder panel….. there are 4 options:

1: Generic
2: SD DVD
3: Blu-ray
4: HD DVD

I am using HD DVD (1440×1080).
The average and max bitrate goes from 10 all the way up to 29.4 mbps.
This is what i’m looking for a suggested bitrate.

Thanks for your help!

HD DVD is defunct. You have an HD DVD Player?
The viable optical video disc formats are SD DVD or Blu-ray . . . unless you have a defunct HD DVD player which you haven’t replaced . . . and I can’t think of a reason why anyone would be in that situation given the price of Blu-ray players these days.

Yea, I echo Craig…hddvd lost the war, Bluray came out triumphant 🙂

I’ve had zero experience with hd DVD.

Here’s some good ‘average’ starting point.

SD DVD: 4.5 mb/s.
HD-DVD (MPEG-2) 18 mb/s
HD-DVD (h.264) 15 mb/s

Blu-Ray (h.264) 15mb/s

You really need to specify what you’re creating:
An HD-DVD (defunct)
A Blu-Ray DVD

Jeff, I have been looking for a start point (avg.) on h.264 blu ray for compressor. I usually have around 5-8 videos that add from 60-90 minutes. All shot on canon dslr 7d, 5d, and vixia hfs10. Do you still think 15mb/s is a good avg based on number of videos and time limit? What would you recommend for a max? Do I check multipass? I have been exporting apple prores 422(LT) 1920×1080 24p 48 kHz. Should I export different format for compressor 3.5 before or just keep to my editing preferences from final cut?

thanks.

Apple’s preset is a good place to start. If you’ve converted to ProRes at the beginning (and boy, I hope you have) the biggest issue, is the frame rate. Run a difficult (lots of motion) 30 seconds through the Apple Preset for Blu ray…and then up it by 10 percent to compare about the way it looks.

I’m hoping that you’re using SEND TO Compressor – if you’re doing this, great. Saving it out as ProRes induces another compression cycle. Compressor will ignore the codec of the timeline when it does it’s compression.

thanks for the tip Jeff. I will try it out and let you know.
