  1. Hey everyone. I've done some reading and viewed some old threads and decided it was time to actually login and get some help. I am a boxing head and I have tons and tons of old fights on dvds. I spent so long trying to get the hang of getting the fights on dvds, I haven't been in any hurry to move to blu-rays. I think the time has finally come. The world of boxing, we get video from all over the world in varying formats and qualities. What I am looking for or need some instruction to read on is:
    1.) Can I move all my old fights from DVD's to blu-ray for space? If so what changes would have to be made? I don't care about keeping menus etc. I can author new ones.
    2.) Can I mix stuff up? For example I have MPEG videos to start and some newer fights will be HD.

    What I am thinking is that I will rip each individual fight off the DVD's. Then if I have a new fight in HD, I will add that to the mix. I have no idea what format a BD requires though. Am I simply able to author the Blu-ray with mixes of MPGII and other formats?

    This is not a quality issue. This is more of a space issue and keeping HD in HD formats rather than scaling it down so it will fit on a DVD. Chronologically, I will have a fight that is SD then goes to HD then back to HD or some weird combination like that.

    Take a look above at the "What is..." section.

    It shows that most of what is regularly used for DVD (MPEG2 SD D1 interlaced video, AC3 or LPCM audio) is totally compatible within BD, in addition to BD's expected AVC (or occasionally VC1) HD video and DTS or lossless forms of audio. Now, depending upon structure, you may not be able to put both forms within the same titleset, but there are ways to get them to reside on the same disc, or easily put them on separate discs.
    Note that there are some elements that don't work - MPEG1, or Less-than-SD-rez MPEG video, MP2 compressed audio. And yes, menus will not translate anyway (they're completely different formats with differing capabilities).

    IIWY, I'd get a full-featured BD authoring app. Adobe Encore (you should still be able to get Encore CS6 by getting Adobe CC and then DL'ing the Premiere CS6 bundle as well for free). Or DVD Architect (was Sony, now owned by Magix). Blu-Disc Studio. Don't think you'll need beyond that (Scenarist, etc.)
    Not necessarily cheap, though.

    May want/need to extract your mpg + audio as elementary streams, as they will need to be recompiled & remuxed from VOB (MPG2-PS) to M2TS (MPEG2-TS) during the authoring anyway.

  3. I think I can do that last bit with video-redo.... I have an option to save the video and it says "remux entire file" to a large number of formats... one of which is mpeg-2 transport stream (.ts) file extension.

    That's not hard. I love video-redo. It's possibly the greatest single piece of software I own. Can handle just about anything I've tried to do.

    Thanks for the info. Will look at all of the mentioned above. I think, at this point, I should be able to get everything straight off the discs, use VRD to move to a .TS file, then get after it. This would vastly cut down on space and allow me to squeeze some whole career sets on BR discs. I've always been good at finding work-arounds and getting stuff to work. Usually just takes some time and perseverance. I think with your help, this should be gravy.

    Thanks, much appreciated. If anyone else has anything to add, I'm all ears to tips/tricks etc. that you've learned along the way.

    SD rez MPEG2s are not wonderful in their robustness to further compression, particularly if some of your material is taken from broadcasts/streaming.
    So tread lightly in converting from mpeg2 to avc (as that last "squeeze" post of yours leads me to believe).

    Sorry, I'm not sure what you're meaning on that post. If I understand, you're thinking that my MPEG2 files won't look very good if change them from mpeg2 to mpeg .ts files?

    Moving mpeg2 from vob (mpeg-ps) to m2ts (mpeg-ts) by reauthoring+recompiling is just a container change for the existing mpeg2 video - no loss, no diff in quality, slight change in header overhead-, but if you intend to "save space" by re-encoding your mpeg2 video into avc video (in addition to the container change), you run the risk of worsening the quality.

    Dunno if its updated anymore but multiavchd did that for a few years ago.not the easiest thing but it took a mix of mpeg2 files and reautored them (no recoding) to a bluray disc. If you want something a bit easier and don't mind recoding look into tmpegs authoring products. The cost some cash but will do all the proper work for you
    if all else fails read the manual

  10. Alright gentlemen, authored my very first disc last night (TOOK FOREVER)!!!!! I didn't see a place to ask an Encore specific question so I'll ask here. Mods, or whomever, if you don't mind moving if necessary.

    I had a bunch of MPEG2 files that I added in, built a menu etc. etc. However, after our discussion above, I was under the impression that the files did not need to be "transcoded" by Encore. However, it transcoded them anyway...... below is the mediainfo for two separate files. One transcoded, one not transcoded.

    This first was not transcoded:

    I'm not sure why it would transcode one file and not another???

    Don't at first glance see anything video-wise that would necessitatetranscoding, but your 2nd sample's audio is mp2, which is "allowed, though not preferred" in DVD, but is NOT allowed in Blu-ray.
    My guess is that Encore flagged it as needing transcoding due to the audio, but transcoded the video also for good measure (maybe to make it progressive?).

    MediaInfo does not show everything there is to know about the encoding. FFprobe, part of FFmpeg, provides more analysis.

    I thought that the Blu-ray spec requires standard definition video to be encoded as interlaced. Is there an omission in the specs posted here at VideoHelp?

    [Edit]If the goal is to avoid re-encoding and the video is not Blu-ray compliant, then it is possible to burn simple media files to Blu-ray as data. There is no menu of course, but many Blu-ray players have the ability to play DVD-compliant mpg or ts files.

    That's why I said "at first glance".
    Specs/WPs say that BD SD main content material should be interlaced (though it usually/often accepts PsF material) but that secondary/PIP material should be progressive (weird, huh?).

  16. Gentlemen,

    I've uncovered a few noteworthy facts that I didnt see before!!!!!! So, I instantly took the file to VideoRedo and changed it from MPEG2 to M2TS. Thinking, surely this will fix the goose! When I tried to add it back to Encore, it still wanted to transcode... I noticed that Encore is seeing the files as 864x480. I think this is my problem. 864x480 is not compliant. So, I went ahead with M2TS and switched it 720x480 and asked VRD to change the video and letter/pillar box it. It worked, added it to Encore and it said it still needed to be transcoded. So, I'm changing the audio since above it was mentioned that the one file I added had a non-compliant audio.

    So, I went to MPEG2, for some reason the M2TS wouldn't work no matter what I tried. I think the only two audio options I had were both wrong.

    Cornucopia and everyone, Thanks for the help. The little bits and pieces I am picking up are proving invaluable.
