The complete HD (Blu-ray/HD-DVD) back-up thread.

Your download could be damaged or incomplete, try to re-download. The RAR package is fine.

 

tried it twice now, will try one more time.

 

I must be having bad luck today because im still getting the same error. I'm using winrar 3.91 I believe thats the latest version.

 

Try WinZip. WinRAR worked fine for me.

 

Ah, thanks for clearing that up. Still looking forward to the results! What that means to me is that I'll be able to lower my bitrate and supposedly achieve better results. I typically use between 10k and 15k. I'll try 8k and see if I'm visually convinced. Or 8k with the old and 8k with the new.

 

Tried winzip, same thing happened. Mediashare is performing maintenance until 3, ill try again after that.

 

finally got the zip file to download.

I am fairly comfortable with demuxing files, converting audio using eac3to, and muxing to m2ts with tsmuxer now. My next step is to convert some BD rips that I have that have VC-1 video. I want to be able to stream these so I need to convert the vidoeo to h264 correct? I'm wondering what is the easiest way to do this? I don't really care about how long it will take, and file size is of no concern either, I want the best quality possible more than anything. I was thinking of using MeGUI to do the conversion, is there a easier/better program to use? If I sue MeGUI, which profile should I use? Thanks in advance for any help.

 

Are you streaming to a PS3? If yes, there is a way without re-encoding... and I see you already have an external HDD with a lot of space... which is also required.

 

yes I plan to stream to the ps3, and actually I do not have an external drive at the moment, my external enclosure is broken so the drive is internal at the moment. so for now I just plan to stream over my network with ps3 media server, which is why I have been converting the dtshd audio tracks that I have to lpcm, and also why I need to convert the few VC-1 rips I have.

 

OK, when you demux your video stream either use eac3to and demux to MKV, or use tsMuxeR are remux to M2TS. Use that file and re-encode using one of Ryu77's profiles. I suggest you re-encode to a couple of GBs smaller than the source, and use his fastest blu-ray profile. The video wuality will be pretty much identical.

 

Is there an option in MeGUI that let's you specify the size of the output file?

 

Yup. Tools --> Bitrate Calculator. You can specify in File Size, or Kb/s. I always use File size.

 

Hey peeps

I need some help/advice.

I have an HD MKV file of 4.37GB in size and i want to burn it to a DVD but for it to be compatible with blu-ray players so i keep the HD goodness.
*EDIT*

Just downloaded video inspector and it says the the C0dec is MPEG4ISO advanced and the audio is 6 channel DTS


Now i have visited the links in this thread but am still not sure what i should be using or how.

Please help a noob in need.

Thanks

 

which of Ryu77's profiles is the fastest then?

 

"Standard Quality" would be the fastest. Since your output will have pretty much the same video bitrate you do not need to use a better quality profile.

 

ok great, ill give it a shot. thanks for the help!

 

Please excuse me for jumping in but please keep in mind no matter what bitrate is being used, you are still performing a lossy encode so there will still always be benefit from using higher quality encoding parameters. This would still be the case even if you were using a higher bitrate.

However, in the higher bitrate ranges, there is less importance on using the higher settings as the higher bitrate usually is enough to ensure good quality.

I think there is a bit of a misunderstanding with bitrates and how lossy encoding works sometimes. Anytime you are encoding something through a lossy encoder, there will be "some" information lost to compress the size. Basically this is what happens...


Raw uncompressed video (RGB)--->Lossy Encoder (h264/VC1/MPEG2): The production studio will begin with a raw uncompressed video (for 1080p, this could be approx 500GB in size) that will be authored so that it is ready for distribution on Blu-ray disc.

Blu-ray Disc/HD Video (Compressed Lossy)--->Decoder: The decoder will decompress the video back into the raw RGB information so that it can be viewed through the player.

Decoder--->Encoder: Even though it has been decoded into uncompressed video first, there is still some information lost from the previous lossy encode that can NEVER be recovered. So re-encoding this material again, will re-compress the video with lossy algorithms, therefore losing slightly more information again no matter what bitrate is used. The goal though is to keep the loss as minimal as possible, which is why the higher the bitrate and encoding parameters, the better.


Please excuse me if I have stated things already known, I just like to keep things clear.

 

Ryu77, thanks for the clarification on how the encoding actually works. So basically I don't need to worry so much on which encoding parameters to use (standard, high quality, etc.) and just focus on the bitrate of the output video stream? So, using odin24's suggestion to use the file size option in the bitrate calculator, if I just specify the output file size to be roughly the same size as the input file, I will achieve roughly the same bitrate correct?

 

Of course the parameters are important. They improve quality at the same bitrate but slow down encoding. My point was that when bitrate gets high enough, the slower parameters have less impact.

 

ok I get what your saying. basically since im using a high bitrate, the difference in quality between using a slow profile or a faster profile will be minimal.
