Converting bluray to MP4... or whatever format is better!

    Hello,
    Even though I created this account many years ago, I'm actually new around here. So sorry if I am posting this on the wrong place, or if the question is redundant.
    Anyway, I have a quick question about converting blurays to MP4.

    I am a teacher and I'm always showing movie clips in my classes.
    I usually get the clips from my own movie collection.
    In order to get the clips, first I rip the entire movie to my computer.
    To do this, I use a very old version of DVDFab and convert the movie to MP4.

    Once that's done, I use Freemake Video Converter to edit the clip that I need.

    I used to do this with DVDs, but lately I've been using blurays. I thought that the quality would be a lot better, but it is not as high as I was expecting.
    I think that the way I am converting the bluray to MP4 is not the best.

    I was wondering if someone out there knows which video format is the best to preserve the quality of the video.
    Also, having to rip the entire movie just for a clip is not the most efficient way to do this.
    So if you happen to know a better way to get the clips without having to rip the entire film, please let me know.

    Also, if you have any software suggestions, feel free to share. If the software happens to be free (like Freemake), even better!


    Thanks a lot!

    There are three different ways to make lossless Blu-ray backup.

    Method 1: 1:1 Full disc copy of Blu-ray

    A full disc copy will helps to preserver the original structure of the Blu-ray movies with all your wanted subtitle languages, audio tracks and chapter markers.

    Method 2: Lossless Rip Blu-ray to Uncompressed MKV Container

    MKV is a flexible, open standard video file format that has quickly become the preferred file extension for high definition video on the Internet. The MKV container can include video, audio, and features such as alternate audio tracks, multilingual subtitles and chapter points, as well as rich metadata including cover art, ratings, descriptions and more. MKV offers a richer media experience than any other current format.

    Method 3 Remux Blu-ray

    Blu-ray remuxing is a lossless process that simply takes the video and audio streams from Blu-ray M2TS container and puts them into a new container like MKV, AVI, MP4, 3GP, etc. Remuxing is for those who don’t care that much about extras in the source Blu-ray discs and want to save space while having the movie in a new container so they can play the Blu-ray movies easily with any video player with the same quality as that of the untouched.

    You can easily achieve that with a simple to use Blu-ray Copy software called ByteCopy.

    Technically, MKV is better. MKV format is able to hold unlimited and any type of audio, video and subtitle streams. You can put a complete movie into a single file including various audio, video and subtitle streams as well preserving menus and chapter structure. You can find everything in a MKV file when coping and converting DVD/Blu-ray movie to MKV. You can try to read this.

    MKV and Mp4 are both containers and not encoding formats. The video quality of both are the same dependent upon the codec because both use H.264/X.264 for the best possible HD. Where you might have to decide on MP4 over Matroska is if a device you're using won't recognize and play MKV files, and there are quite a few that won't. So the real answer is know your devices! Audio is usually of the least concern because most people are looking for a small package with good audio and dts 5.1 sound increases the size of that package. If size is no issue then just make a compressed BD, and take out all unwanted audio formats. I used to regularly compress and burn BD to a type 5 disc, and occasionally a type 9.

    Agree with file size increasing for better quality.However it depends what the original recording was from/done on,not all movies on a blu ray disc are equal

    All copies depend on the quality of the source, but that's something you can't control unless there are multiple versions of a BD. For instance I have a copy of King Kong on HD DVD and BD, and the HD DVD copy was in my view a better transfer because to the eye it looks better. The other issue is that BDs' are encoded with different codecs such as H264 or H262. A lot of people might be surprised to know there are a number of BDs encoded in MPEG2. Blu-Ray offers a file size that far exceeds the requirements needed to produce HD video which is why MPEG 2 works, and why most BDs' can be compressed up to a third or even a quarter of the original size with good quality using H264/X264. The fact is that high definition video could've been released back when we were all still using type 9 discs just by moving from H262 to H264 which is more efficient by a factor of 3 or more times.
