OK; i just tried to make BD from a mkv (h264)
Original was 390 MB, created m2ts has been 410 Mb ; means ten percent increased.
So it might be told that re-encoding to a 3.5 GB m2ts file will be safe enough for burning a DVD.
(I was comparing the lenghts of m2ts file and created BD Folder.)

Your increase appears to be a 4.9% increase (390->410) and the conversion that I just ran came out to a 5.1% increase (74.5->78.5). I don't know if the results are linear but when I get home I'll have to test a larger file.

The size increase has to do with the size of the source file, the larger you get the more room you'll need.

For a DVD9, the header space for m2ts/blu-ray muxing is 570mb. For a DVD5 it is 313mb. For a BD25 you're looking at just over 1GB.

Yes; %5*2= % 10 for safe

while removing pulldown from MPEG2 video stream (30fps) it must be also flagged as progressive. Else with created blu-ray output we got blu-ray with incompatible video stream (progressive 24 fps not marked as progressive) and stuttering playback on PS3 (and possibly all others stand alone br players).

I use this formula:
Taget size
---------- x 100 == "max size" before muxing into BR/AVCHD
110

Then before encoding do:
Max size -/- (size audio + size subs) = max size for video. Give that number to the bitratecalculator (in Megui).

Have you tried using "Auto Encode"? Using this feature MeGUI will calculate the video bitrate to acheive the "max size".

Yes but muxing into BR / M2TS requires approx 10% overhead, hence the pre-calculation

You only need 7% of a DVD9 (8152mb) reserved for the m2ts header, which comes to 570mb.

My best format to fit on a DVD is to get the audio down at least 300mb. Usually if I have a 640kb 6 channel I will convert 224kb 6 channel. Then TSmuxeR converts that close to 4.37gb. The video I never touch.

That's if the MKV you have is 4.37gb to begin with.

Overhead is not constant! it changes according to movie length , audio type , audio bitrate.

Isn't is though, to a certain extent. Assuming you recode to a specific media size (DVD5, DVD9, BD25). I rip my own BDs, recode to fit to DVD9 with DTS and subs, really the only constant there is there is the fact the BD/m2ts header is going to be 570mb.

On the other hand, if all you are doing is converting (mkv-->m2ts) and streaming/copying, then yes I agree, the header will be proportional to the source file and it's streams.

[n0mag!c]

As Atak_Snaipera says: "Overhead is not constant!"
For instance, headers (as you use this term) size of 180 min movie will be two times greater than of 90 min movie.

Maybe I'm not clear on what a header is then, all I know is; regardless of how long, or what type of audio is used I always reserve 570mb of a DVD9 that I cannot use for any A/V stream.

I'm not trying to sound rude or cynical, but what exactly is a "header"... I thought knew what it was?

[fib0by]

For a 8150 MB target (2-layer DVD), I subtract the sizes of the "naked" AC3 and SUP tracks from 8150, and use the result to calculate the "ideal" bitrate for the .264 track. Then I multiply the "ideal" value by 0.95 and that's what I use for x264 in MeGUI.

So basically I assume there's a 5% overhead for one .264 track, one AC3 track, and one SUP track, muxed/authored with tsMuxer on a 8150 MB disk.

Seems to work OK so far.

hi

why some movie cnot can convrting at the tsMuxeR?

and some movie its make a green line in the downd screen why?

i can fix that?

tanks!!

Thanks

I have the excact same issue, the only difference is that I am burning my back-ups to a BD-25 and playing them back on my Panasonic DMP-BD50.
With TrueHD discs my Panasonic just refuses to play them, when remuxed with TsmuxeR, but if I remux them again with TsRemux and then replace the original m2ts stream from TsmuxeR with the new one from Tsremux and then burn it all is ok.

The "funny" thing is that the Tsremux output, when burned to a BD-25 wont play on the Panasonic either, strange....

But if there is any one out there with a Panasonic DMP-BD50, I can confirm that this work around works for it

I didnt think of trying that method, anyway it works but i still have a problem with rewind & fast forward playing back on the ps3.
