  1. Can someone compare these 2 format? Which one is better?

  2. That's an interesting article Baldrick, but I'm not sure how it compared H.264 to MPEG-4 AVC. The author seemed to group them together at the beginning by saying that "H.264/MPEG-4 AVC" will be simply referred to as AVC.

    MPEG-4 AVC is based heavily on H.264 technology from what I remember. Similarly, regular MPEG-4 is based on H.263. The MPEG group I think just comes up with standard methods of implementing the technology in a container, file structure, encoding methods, etc..

    I know that the H.264 was created by a jointly work of the International Telecomunication Union (ITU) and the MPEG comitee, and so they created the "ITU-T Recommendation H.264|ISO/IEC 14496-10 AVC", otherwise know as MPEG-4 part 10 or H.264.
    I don't think that the MPEG comitee just comes up with standard metods of implementation and other similar stuffs.
    The same for the MPEG-4 part 2 (ASP, the actual DivX, Xvid and other MPEG-4 codecs).

    AVC and H.264 are the same thing (only different names, AVC for the MPEG comitee, H.264 for the ITU).

    This is an excellent MPEG-4 faq.
    Anyway I don't like DivX (I prefer XivD), but for me the best is Nero Digital (AVC and HE-AAC codec, the fastest and best performance).

  6. I only use Nero Digital. Its fast and looks the best under high compression.

    I don't know about high compression, but I really like Nero Digital for the fast and the quality (I have an old PC, and with the max settings, like 2 pass encoiding, and extra quality, it take about 8 hours for a 2 hours movie).
    I'm also going to purchase the Xoro HSD 415 for the Nero Digital compatibility, also if it's not sold in Italy.

    Finally i managed to try nero digital, i was surprised by the quality of image, quickness( 2 hour movie took 1 hour to encode in one pass mode) and multiple audio and subtitle support.

    if divx 6 doesnt bring anything new i will be switching to nero digital

  9. I just tried Nero Recode too and I was amazed by the encoding speed and the picture quality. The MP4 files play fine on my friend's RJ-1500DVXII. In my opinion Nero Recode is much better than Dr. Divx. Dr. Divx is too slow and it has too many bug. Do you think Nero MP4 format can replace Divx in the future?
    Quote Quote  
  10. I think that it should replace DivX at least because Nero Digital is a complete back-up tool (video, audio and subs), DivX is just a slow (and not really powerful) MPEG-4 encoder, and it lives of his name.
    I have a question:does the RJ-1500DVXII support the raw AAC without the upgrade, or not?

  11. He bought it from MyVirtualzone.com it play Nero MP4 out of box. I think the manufacture just release their firmware update recently.

    AVC = h.264.
    DivX = DivX ASP MPEG4 video in a hacked avi container with mp3 audio. DivX container supports XSub's, chapters and menus.

    Nero Digital in this case = ND ASP MPEG4 video with lc aac audio (any players support hc aac audio?) in an mp4 container. Chapters and vobsubs are supported.

    Nero Digital also has a main level AVC encoder.

    Should point out that a DivX avi can be muxed to mp4 and mp4 remuxed to avi and in mp4, MPEG4 = MPEG4 so you can just as easily use XviD, libavcodec, HDX4 or whatever... not just ND.

    So I guess the only thing that DivX has or rather will have over ND is menu support, although strickly speaking mp4 supports much more advanced menus, as well as 3D and other advanced content.

  13. Well, at the moment Nero digital doesn't support all the MP4 features, like menu and 3D animation.
    http://Should point out that a DivX avi can be muxed to mp4 and mp4 remuxed to avi and.... not just ND.
    Yes, you can easyy remux an .avi with DivX (or an other MPEG-4 ASP codec) and mp3 in a .mp4, but you have to convert the audio to convert an .mp4 to .avi, .avi doesn't support AAC. Anyway Nero Digital is faster 8and maybe better) of those other codec (it isn't free, I know, but my OEM Nero 6 edition include Nero Recode 2 and Nero Digital encoding).
    http://(any players support <a class="contentlink" href="https://www.videohelp.com/tool...a> aac audio?) I don't know of any player that supports HE-AAC, all the player will play it, but just because is backward compatible (but the quality is low). The Nero Digital Standard and Cinema profile don't include HE-AAC, only LC-AAC.

    Yes I know Nero doesn't support menus or anything like that. I haven't heard any plans to support it either, nor to support ttext subs, which would save space over VOBSubs, plus if fully implimented I believe the format is capable of colour changes/animations. Just pointing out that it is possible under the specs.

    avi does support aac audio, I just wouldn't expect any hardware to support playing it back.

    Well yes, any LC aac decoder will decode he-aac, but as you say the quality is low without the SBR part.

    I've heard that .AVI doesn't fully support AAC and infact there isn't any encoder to use with VirtualDub, I've heard that there was some experimental encoder, but they were really bugged. Have you ever created an .avi with AAC?

    I don't think that VOBSubs are so expensive with space (just some MBs, I think), but the the ISO part of the txt subs is one of the newest parts, and Nero recode 2 wasn't able to use them, the txt subs should be also converted, and this will take time. Anyway actually there are some profiles, and Nero will use them for a while. Do you know about some player that can read the MPEG-4 txt subs?

    No idea about ttext subs and hardware players.

    So if VDub doesn't support it then it isn't possible with avi? Personally I wouldn't recommend using ACM compressors anyway. Even for mp3 I would convert externally.

    AVIMuxGUI has been able to mux aac into avi for some time now.

    edit: wouldn't not would.

    Well I've done some encodes with Nero Digital and the Home Theater Encodes are pretyy impressive, I made an Encode of "Assault on Precinct 13" that in a 2.2 GB file looked as good as the 5gb DVD. But that quality came at a price I think it took about 12 hours so have a hefty machine....

    I'ven't tried yet to do so big Nero Digital, but with the Nero Digital Standard Profile (that I usually use) it takes about 6-8 hours with my old P-III. I have tried once the HDTV profile (not AVC, the ASP's one) and it takes about 12 hours if I remember well. It's little strange so long time to encode a movie (I don't think that it took this time 'cause the file have a very high bitrate) which machine have you used?
