Best Way to Back Up a Blu Ray Disc Main Movie Only under4GB for PS3 fat32?

[Ps3riiper]

Hi Guys-

I'm new here and I have searched and searched.. There are many of Torrent Sites that have Blu Ray Rips under 4GB total file size, typically like 3.99 for the Main Movie Only. I have a PS3 connected to a External HD Fat32 and need the total file to be under 4GBs. I already have the ACVHD program to switch back and forth for the movies that I want to be big file sizes, but for the only that are "mediocre" I want to back these Blu Ray main movies up under 4gb file size..

I first need to know how to take off the DTS audio and switch it to the AC3 5.1, then obviously make the file size of the blu ray main movie to 4gb. Please help me guys! and here is an example of the what the PS3 team is doing on the torrents :


Specifications

* Codec -----------> H.264
* Resolution -----> 1920x1080
* Average Bitrate -----------> 3.6
* Framerate ------> 24fps
* Audio ------------> AC3 Dolby Digital 5.1CH Surround (384Kb)
* Subtitles --------> english subs for african dialogue
* Extension -------> M2TS
* Source-----------> Blu Ray Disc
* Movie Trvia------> Leonardo DiCaprio and Russell Crowe were Edward Zwick's first two choices for the role of Danny Archer.
Procedure And Testing
* This file is kept under 4 gigs for easy storage (Dang FAT32!) Hi quality 2-pass H.264 standard encoding.
* THIS IS MEANT FOR PLAYBACK ON THE PS3 and was Tested on Sony Playstation 3 (Firmware 3.00) with a large 52” screen (LCD
) HDTV .

I am assuming I'm going to have to use RipBot264 for the video and set it on 2 Pass .. and change the file size to something under 4gb.. but how do I go about changing the audio from the DTS to AC3 and maintain the 1920x1080 resolution in Ripbot264? Please help me guys.

For under 4GB I would forget 1080p and go for 720p instead. Anything over an hour or so will really suffer at full 1080 resolution.

[Ps3riiper]

Hey, thanks for the reply.. That sounds good to me since you seem knowledgeable so 720p it is.. What is your recommendation for under 4gb file just like they have with the AC3 5.1 sound or just dolby digital sound.. I just want to get rid of that DTS audio track in Ripbot as it is the only english audio I am getting on these newer movies..

So as far as the video part goes..
1. I just copy the blu ray to hd with Anydvd.
2. Open up Ripbot264 and select the biggest video file
3. Select the DTS HD audio? There is no AC3 that is english?
4. Ripbot264 automatically remuxes the audio
5. Click on 2 pass and AVCD for blu ray quality
6. Lock the size to under 4gb?
7. Go to settings and change the resolution to 720p
8. Click Start and then wait a few hours..

Does that sound about right? Any help would be appreciated.. Again, I just need the file size to be under 4gb .. I really would like 3.99 gb so what would my file size be? Thanks!!

You will about have to use AC3 audio or your video quality will really suffer. DTS audio is at least twice the size or bigger than AC3.

Here's a BD>MKV conversion I have done with a target filesize of 4.37GB to fit on a DVD-5. I know you need to go smaller, but it's all I have for comparison.

1hr 53mn Duration
4.37GB total filesize
3.77GB Video filesize, 4761Kbps, 1920 X 1080, X.264
519MB Audio filesize, 640Kbps Audio AC3, 48Khz, 6 channel

Assuming the audio will stay about the same size, I would have to reduce the video bitrate to shrink the file.

I chose a target size of 3995MB total, probably a bit too large to end up under 4GB, but it should be close. From a bitrate calculator:



You could see that the video bitrate would need to be about 4280Kbps for this example, down from 4761Kbps. But reducing the framesize to 1280 X 720 would give you the best use of that available 4280Kbps video bitrate. The video file would then be about 3.46GBs.

Hopefully I didn't mess that all up too bad as it was a quick layout.

Thanks for the good, quick reply sir.. I appreciate it. That all makes sense. I am just trying to find the right software to go about it.. Any suggestions? I want to convert the DTS audio to the AC3 you recommended (I believe it is the 5.1 digital dolby) and have a 720p picture at the bit rate you listed. Please recommend the best way about going about this software wise. I just want the end result to one nice m2ts file so I can just copy to my ex hard drive and direct stream through ps3. Thanks!

Another method (notice I did not say "best"):

Use BDRB. In setup, you can specify that it re-encode to 720p, re-encode the audio to AC3, and you can easily set a custom file size. If you choose movie-only and re-encode the audio, you may find that some (<2 hr.) movies will look acceptable at 1080p. Try it and see. Many here are very sensitive to picture degradation and compression artifacts; they know what to look for. But evidently others are not, judging from their claims for 1080p to BD5.

Good luck. Oh, and welcome to the forum.

[Ps3riiper]

Thanks for the reply fritzi.. I used that software and was not very satisfied with it... but then again, this blu ray ripping stuff is annoying me because of how long it takes to process.. I really need to get a quad core or something similar instead of this dual core.. Hopefully it will speed up more with a quad core, but i have still heard it isn't that much better :/.

Redwudz- how are you getting the total file size for the video? I cannot find out ho you are coming up with the 3995 value for me. I'm wanting to do a movie that is 1hr 59 minutes and 05 seconds long at either exactly 4gb or around 4gb (like 3.99 or similar). and I have a 640kbps ac3 audio that is 545mb in size. Please help, thanks

I just input the running time of my video and threw in a custom output size and the calculator came up with the bitrate. I could have used 4GB, but I opted for a slightly smaller file size to allow for errors. Even that may be too big, it depends on how accurate the encodes are. Bitrate can be somewhat variable for a certain output quality. A video with a lot of high speed action like a Kung Fu movie needs a lot of bitrate to keep from artifacting and blurring in fast action. A TV interview can use a low bitrate and still look good. Either way, more video bitrate is usually better. If your audio bitrate is fixed, then all you can do is adjust the video bitrate.

Try a calculator with the info from one of your processed videos and see how close it comes to what you have. Usually it's fairly close on guessing the file sizes and bitrates. In my example, it's mostly a demonstration of what you might need to do to reduce file size and help to understand the relationships between running times, bitrates and file sizes.

From your data:



I don't know if I mentioned it, but I used the VideoHelp Bitrate calculator.

Thanks for your help man. I downloaded the program and it is very easy to use I am going to try it in program that gunslinger recommended to me . Will post the results

PS3 Ripper: Here is how I have been doing my rips so far:

MakeMKV : I use this to rip Bluray disc to PC. The latest beta decrypts the disc for you as well. No need for AnyDVD (although I still use it for some BD+ discs)

MakeMKV gives you the option to choose the video audio and subtitle streams, and gives you one mega mkv file No need to search for the biggest file, correct audio track, subtitles etc. All listed in an easy GUI. It takes about 30 mins per bluray


Ripbot 264: Using a similar bitrate calculator as listed here, Ripbot will convert the mega MKV file to a 4GB MKV file. Ripbot automatically demuxes the audio and video, converts AAC/DTS audio to AC3 and remuxes it back into the compressed MKV maintaining the 5.1 surround sound. I also normalize the sound to 100% because many movies in 5.1 sound are too quiet and too loud at action scenes (this process @ 2 pass fixed 4000MB filesize takes about 12-14 hours)

TsMuxer: remuxes the mkv file into a .m2ts file (here I change the profile to 4.1 for PS3 playback)

Done!!


Based on these settings I am getting excellent rips... no pixellations. However ... when there is a single color displayed on the screen (like the blood dripping down the gun barrel in bond movies) I get pixellations and blocks. But overall super quality.

I'm looking for an authoring software that can put all these movies BACK on a BD disc with menus without reencoding the files (roxio and nero reencode). This will allow these files to be played on a standalone BD player (5 movies on one BD)... anyone know of such a software???????

Hey guys I have a question regarding the same issue. I used DVDfabHD and it ripped my main movie file fine, but not too sure what to do from this point. I have tried converting to mp4 using avs video converter and it plays the movie fine but the sound isn't working. Should I use ripbot or TSmuxer before converting with AVS??

thanks in advance
