.MKV conversion

You are still going to lose quality streaming it. It'll end up about DVD quality streaming it through the PS3. Only way to watch it in HD is to plug it in HDMI or DVI from a laptop to the TV.

m2ts HD files are typically coded using VC 1 from my observation.
When dealing with lossy re-encoding you can only decrease the theoretical information content.

But video and audio coding capitalizes on human perception.
Assume you use pass through with audio so it stays the same.
Using Handbrake you can re-encode video using AVC/H.264 with at least a 4:1 reduction in size and get perceptually near identical HD video quality. Then place video and audio in an MKV container.

Using an Intel Core 2 Quad @2.5GHz the process may take ~ 7 hours!

All you need is TsMuxer.

Use it to create a AVCHD format.

Youll have a folder thats a Bluray type structure. Just add the the 2 folders to the disc and burn to DVD or DL-DVD with ImgBurn.


So long as the encode itself follows Bluray/AVCHD specification, it will work.

The source file can be MKV or even a MP4. All that matters is that the streams are compliant.
Typically, H264 video stream with AC3 or DTS audio stream.

Yep, Just a regular DVD or Dual LAyer DVD writer is all you need.
However, you will need a a BluRay Player to play it back.


As far as quality goes, Ive found if you downsize to 720P, you can get some really good looking copies on a single layer DVD, or DL for longer films.

You can keep it at 1080P, but many times, they come out just as well or better as a higher bitrate 720P copy.

It really depends on the the length of the film, and what media you're using.

If just just single layer disc, Id say downsize it to 720p, and go with as high of a bitrate as you can.
So you keep it looking as close to the original as possible.

It will not be operfect, but many would find it difficult to notice the difference.

Wierd ...

TBH, Im not familiar with Handbrakes settings.
Perhaps theres something Handbrake does that overides these settings?
That or Im missing something.


But, TsMuxer shouldnt try to change the bitrate. All its really doing is De-Muxing the Audio and Video from the MKV or MP4 file, and remuxing them into a MT2S container.
Bitrate should stay the same as it was when it was encoded.


Im a bit confused as to why it would be doing this ...


Do your TSMuxer settings look like this?


The major things that need to be set in the encoder should just be:
Ref. frames = 4
BFRames=3
KeyInt=24
MinKeyInt=2
BPyrimid=Strict
VBV Buffer 14500
Max Bitarte 14000

These settings should make the Video Stream BD/AVCHD compliant.
So bitrate and file size should all be done via the encoder itself.
