View Full Version : Mmm... OGG container not so good about frame-overhead... :(

Some days ago I have read from an expert member (I don't remember who... maybe everwicked, maybe at www.everwicked.com)
that OGG multimedia-stream-container permits very low or low frame-overhead on final size... especially when you consider 1 or 2 CD encodings.

something like this:

DivX4_video1 --> OGG (DivX4_video1, OGG_Audio1, OGG_Audio2) = 700 Mb
DivX4_video1 --> AVI (DivX4_video1, OGG_Audio1, OGG_Audio2) = 712 Mb

BUT!

I have proven that happens the exact opposite!
The OGG files are a little BIGGER even if I use only video track,
using graphedit (I know very well this DShow methods) I convert a video-only file "STFirstContactCD1.AVI" (710Mb) to "STFirstContactCD1.OGG" and the result is 714Mb!

WHY???

P.S.: The .OGG files plays *perfecty*.
I have used for source scheme in Graphedit:
"File source (Async)" + "AVI Splitter"
or directly
"AVI/WAV file source"
Must give same exact result... (proven)

and who would make a movie without audio track? my guide contains the numbers when taking a video only avi, and either add a vbr mp3 to it and compare that with adding an ogg audio track and multiplexing it into an ogg container... the latter is 6mb smaller

I see that in this guide the comparison is between
AVI(DIVX4 + VBR MP3) and OGG(DIVX4 + VORBIS)
OK, I understand your target.

Your numbers (overhead) go in favour of OGG because *vorbis audio* multiplex much better that VBR MP3, NOT because OGG container has tight structure.
FOR ME this is the reason.

Because:

Before my first post I have tried to multiplex that movie with Vorbis in AVI and with Vorbis in OGG (container)
The AVI is smaller than OGG.

In fact the better way to save space (and *only* to save space) is to use AVI with DIVX4 and Vorbis audio :D.

Nothing more to add here !! Dont forget guys, the way described in the Q&A using Nandub is only a workaround as we dont have a cutting tool for Ogg now ...
