Thanks,
Use AVIsynth to resize to 1280 x 720. Bilinear is usually recommended for downscaling. Use my AVCHD profile for better quality or use the fast SA_Blu-ray if you want a faster encode.

Thanks Ryu77. This was just a test run, I'm encoding for a buddy who works at a video store... could mean free rents!!!! I did use a fast profile. What he does is uses TVersity and transcodes MP4 on the fly for his 360.
Which brings me to my next question, do you know anything about WMVHD encoding? I got a 360 for Christmas, still in the box BTW, LOL. I think I'll start testing for my buddy's sake.

Hey guys with HD audio receivers,
I just recoded a title, 1hr 43min long, with a 16 bit TrueHD track (approx 1.5GB) to fit on a DVD9... results are fantastic. Fortunately the tsremux workaround accepted the TrueHD track and muxed to Blu-ray fine.
Demuxing the TrueHD track with eac3to will remove the dialnorm and reveal if the track has a bit depth of 16 or 24 bits... bit depth doesn't really matter, as long as the file size is relatively small.
Here are some helpful tips when processing a recode with TrueHD to DVD9.
-The h264 file will have a m2ts overhead of approx. ~340mb
-Mux the TrueHD file to m2ts (alone) to figure out what the remaining overhead will be, combine this with the 340mb from the h264 file, and that's it. Use this to determine the video stream size when recoding.
-Mux to m2ts with tsMuxeR, then remux to Blu-ray with tsremux and burn as usual
I suspect you'd start to notice the video degradation at around a 1hr 45min to 2hr movie.

Can anyone help me with, what I think will be, a very simple problem ? that I cannot solve!
Basically I'm was going to use MeGUI to resize my non-standard sized MKVs adding black borders etc . But when I try and put in the 720 figure, in the 'Resize' field it won't let me! It'll only let me put in a figure that is the same size i.e if the MKV is 1280 x 544 I can only resize it to 544 not to 720. If I key in 720 as soon as I do anything else it reverts back.
What am I doing wrong or what am I missing?
Do I need to manually add the 720 figure into the 'LanczosResize' part of the script?
Any help would be greatfuly received.

Well...one why are you resizing? As in, are the mkvs you have 1080p and you want to make them 720p and add the black borders? If they're already 720p you don't need to resize, you just need to add the borders. My only guess would be to make sure clever anamorphic encoding is off.

I want to create AVCHD disc's from my MKVs (because I want to keep DTS and selectable subtitles) to play on my PS3. I was going to use TSMuxer but I get the green bar going across the bottom of the screen when the source MKV is a non-standard size.
Generally all the MKV's I have are supposed to be 720p but they aren't, they are usually around the 1280x544 mark (some less, some more). So, as far as I'm aware, the only way to get an AVCHD disc from these files is to resize them to 720 and add black borders to them so they equate to there real size again (i.e adding 88 to and bottom).
Is there a better/quicker way of doing this

See that's where you're going wrong. 1080p does not mean that the active area of the movie is 1080 lines. Just like 720p does not mean the active area of the screen (the actual movie image) is 720 lines of resolution vertically. A movie that is 1280x544 is still labeled 720p by scene rules because it's still 1280. They cropped the black bars off the top and bottom...specifically for your example they cropped off 176 pixels. So lets take your example. You have a 1280x544 resolution movie, which will play fine on your computer, because computers can play pretty much any resolution. However, if you burn to a bluray standard, you need to have it in either 1920x1080 or 1280x720 resolution. Your movie is already at 1280 so that part can be left alone. But your movie is 544 vertical pixels with no black borders, and you need to get to 720. So, 720-544=88 total pixels you need to add to get to 720. 88 pixels total to add to get to a bluray standard/accepted resolution. 88/2=44. So, add 44 pixels to the top and 44 to the bottom. If you do that, you have 1280x(544+88)=1280x720. Now you're at 1280x720...there's no need to resize the movie after adding the correct number of pixels(black borders) unless you want to upscale the video to 1080p (which I wouldn't suggest since the movie's already been downsized to 720p.) Hope that helps...let me know if you need me to explain it better...

Hi alcOre
Firstly, thanks for your replies.
Can I clarify a couple of things.
Your first equation 720-554=88 is incorrect. It actually equals 176. Therefore, the division would be 88 (as I stated in my previous post). Is that correct?
Either way ? HOW do you add black borders without resizing (or re-encoding)?
Cheers

Err...yah that's what I mean lol. I was looking at my calculator and I had already divided 176 by 2...anyways. You cannot add black borders without re-encoding. But by adding the black borders you are making the video the correct size, you do not need to resize after adding black borders. You add the borders with a command in your avs script. Use the AddBorders(0,0,0,0) command. 1st digit is left side, 2nd is top side, 3rd is right side, 4th is bottom side. So for your example to add a total of 176 pixels as borders (88 to the top, 88 to the bottom) you would add the following line to your avs script : AddBorders(0,88,0,88)
Your video after encoding with now be 1280x720 with black borders, and compliant for bluray as far as size goes. You still need to make sure its compliant as far as encoding settings goes (reference frames, etc.)

OK. Fine. I understand all that. So here's another probably stupid question. Will adding borders and re-encoding be quicker than re-encoding with borders AND resizing, as I have been? Currently it takes about 17 hours to do both the resize and re-encode.

Just adding borders will be slighty slighty slightly faster than adding borders and resizing. I must emphasize slightly because really its not that much more of a process to resize. If your encodes are taking too long you can lower settings (b frames, etc.) or get a faster processor. I ended up getting a Q6600 quad core because I got tired of waiting a full day (I also encode at fairly time consuming high settings.) The more cores the processor the better...the second pass of a 2 pass encode takes full advantage of every core (as in all cores run at 100% the whole time.) Out of curiosity are you adding borders than upscaling to 1920x1080? Or are you adding borders to a 1080p and downscaling to 1280x720?

Neither! I'm taking a 720p (which in actuality is 1280x544) MKV film and trying to create an AVCHD disc that I can play in my PS3. If I don't add borders TSMuxer generates a movie with a great big green bar at the bottom of it.
I don't want to resize it's just that I thought I had to make the image area 720 high, (which stretches the image) then add borders to squish the image back to it's original ratio.
Since posting I've started looking at 'multiAVCHD' which is supposed to be able to add borders on the fly. My initial test worked (in about 15mins) apart from the disc not being read by the PS3 as a proper AVCHD structured disc, but I think this is more me rushing headlong into it. I'll test it again, being more careful, and let you know the results. If it does work it'll be a darn site quicker than re-encoding all the time. : )

Umm....resizing it to 720 first and then adding borders back and resizing it back is not the correct process. You add the borders...that's it...no resizing. But yes I've heard of that program...never used it myself. Good luck. Let me know how it goes, I'm curious.

hey all,
can someone tell me how i can normalize the volume on a muxed ac-3 file using eac3to (latest stable version). i got it from a blu-ray. it originally had Dolby True HD AC-3 but i wanna get it down to AC-3. i muxed it to ac-3 in eac3to and the movie and when i mux them into a mkv using mkvmerge GUI (2.4.1) the volume is too low. i know it's not True HD AC-3 but the sound sounds too low and wimpy. see it's Tropic Thunder and I want somewhat decent sound. keep in mind tho that i plan to run this finished split set of mkv's on my XBOX360 Elite in time. i don't see a option in eac3to or mkvmerge to normalize the audio. anyone care to help me. thanks!

i just did some researching on Google and discovered that some people just mux the audio into FLAC. i'm familiar with FLAC and use it alot now with music but if i mux it into the mkv's will it be compatible when I run it on XBOX360?

Hey alcOre. Well, I did a test disc this morning and I got a PS3 compatible AVCHD disc with black borders (no green), DTS and selectable subs! All that in less than 30mins (including burning to a DL DVD)! I can't ask for much better than that
So, fingers crossed, that puts an end to my problems. Thanks for all your input over the last couple of days.

Hey BluRayLvr ? I'm a complete noob (as my previous posts with testify) but have you tried AC3Filter! I've used it when messing around with GOTSent and it has a lot of functions that can edit AC3 files. Might be worth a try!

Hi Guys , Complements on the guides and advice - I am new to Blu ray tools and have to admit it's getting a bit over my head.
Following the guide i got stuck at the Megui stage . it gave the error saying there was an audio file not detected even though the guide suggested this was a video only processing stage??
Also I have tried ripping just the movie file and the audio. if the format is ac3 audio it works fine. If however the audio is in hd format I have tried demuxing and then used easy3togui to downconvert to dts or ac3. had to use delaycut to clean up the file. problem is when all is remuxed i'm getting slight stutter when playing from my hard drive.
Any assistance appreciated.

You need to configure where the log file goes. From the main MeGUI screen hit the Config button. There you can specify the logfile destination.
