We were thinking about removing the MPEG-4 codec from the output profile list. Does anyone still use that format? It causes confusion for new users that don't know the difference between MPEG-4 and H.264. Because they are both technically part of the MPEG-4 spec some outlets, especially cable and satellite companies, use the term "MPEG-4" to describe H.264 encoded channels and it confuses users who don't know the technical details.

MPEG-4 codec. Not that I know of?
I think all my .ts and .mp4's are H.264 video.
Is this a container or video format?
If video format is it older than H.264?
Yep, I'm confused about what you're asking.
Could you be more specific?

Ahh, see you're talking about MPEG-4 part 2 which I don't use (and voted so).

mpeg-4 is a video codec released inbetween the release of mpeg2 and h264. The most popular version of it is Xvid. I think Divx might have been mpeg-4 too, not sure.

I might occasionally use it when one of my captures gets messed up and my normal MKV-HEVC recodes don't work. Sometimes for whatever reason it will recode a working video in a MPG format that refuse to work otherwise, even when I try a quickstream fix.
 
I use mpg4, in that I cut and edit it then convert it to M2TS and join it other M2TS files and finally save as MKV. Here's an example of a typical mpg4 file that I use with VRD.

Been using VRD since v4. Never use anything other than H264 & HEVC/H265 . Someone must have a use for WMV, VC-1 & MPEG-4 encode, but never see files using them - seems more of a PRO feature. Wouldn't care if they were all dropped from standard version.

See even people in this thread are getting confused by what I mean. Your file is H.264 not MPEG-4.

The MPEG-4 specification contains a bunch of different formats. It actually contains the MP4 file format, the AAC audio format, and two video codecs. MPEG-4 part 2, what we're talking about here, and MPEG-4 part 10 also known as H.264 or AVC. Part 2 is what we call "MPEG-4" in the VideoReDo codec list. However it's essentially the same codec as DivX and Xvid, as mentioned above. It was used for a short time before H.264 gained popularity because it's has lower processing requirements than H.264 and back then that was still an issue, especially for portable devices. These days almost anything can decode H.264 so basically noone uses Part 2 any more. The combination of low use and high confusion are why we want to remove it.

you could always rename it xvid.
Xvid was actually slightly different and was sort of a brand name. We're actually using the MainConcept "MPEG-4" codec, not Xvid or DivX. So calling it Xvid could potentially cause other confusions.

FYI if we decide to remove it we'll likely add a hidden option to reenabled it, so it wont be completely gone if someone truly needs to use it. Although if/when we release a 64bit version of VideoReDo that codec will likely be gone for good as there is no 64bit version of that particular encoder.

Yes, sometimes people may send or link to home videos which they've encoded in xvid, so not killing it would seen best !

Do you actually save in that format? Or just open?

Opening wouldn't change. We're just talking about removing it as an output codec.
 
I used Xvid for years for encoding M-JPEG, DV avi and mpg2 to reduce file sizes in earlier times, but I never associated it as mpg4. But I did notice that the MP4 files I use today have video encoding as H.264, now I know. As you say Dan203, it's very confusing.

My archives contain some MPEG-4 home video clips, and a few MPEG-4 downloads, so it would be comforting to know I could still input those files should I ever want to. However I can't imagine wanting to output MPEG-4.

Unfortunately, there is no consistency in Australia. Some TV stations use MP4 another call it MP4 but it is actually H.264. The is also a problem with audio, some use AC3 and other use AAC or Mpeg Layer 2. Some players only play MP4 and not H.264 and other players will only play AC audio and not AAC audio. very confusing and I wish it could be consistent. VRD seems to be the only one catering for just about everything. I think keeping it but calling it a different name would be ideal with maybe the onld name in ()
