Reencode Divx4 movies to Divx5 Help

[billharrison]

Hi everyone. I have been using Gordian Knot for the last year to encode movies using Divx4. I have encoded them to 2 cd size, usually between 1.2 and 1.6 gigs is where they end up. Higher res, 128k MP3 audio. Works excellent, and I have a good collection of movies.

Now to the question. What is the BEST way to REENCODE these to Divx5 if I choose to do so. The goal would be to end up with a 1 CD movie that I can play in my stand alone DIVX player. I have heard DIVX5 saves file size without a loss of quality. I attempted reencoding a movie using VDUB, but it lost sync with the sound, and in general stuttered and played back really slowly.

Should I be splitting the soundtrack from the movie before I reencode? Or is there a better tool for doing this than VDUB?

Any help would be appreciated!

Thanks

DivX 5 isn't that much better than DivX 4. I can definitely not recommend reencoding DivX 4 movies to DivX 5.

By the way, if you're doing 2 CD rips you could just as well go for a higher sound bitrate. You can probably take away 100 kbit or so from the movie and use it to the sound without any significant loss in video quality (unless it's a very long movie).

What is that DivX standalone player you mention?

as for the reencoding;

I tried to do the same from 3.11 SBC to DivX 5, and playback is stuttered.

Changing encoding and/or playback settings didn't change it.
(I have AMD 1,9+, so CPU isn't a bottleneck).

My guess is that the stream is corrupted or something. If my mem is correct, the DivX 5 codec also decodes the 3.11 stream, and maybe it "keeps" some of the 3.11 data in a cache or
something --> stuttered playback.

Anyone has some insights on this?

TIA

Reencoding already compressed video is NOT reccomended. Ideally, you would have high-quality, low or no noise, losslessly compressed video source to encode. Recompressing mpeg2 data (dvd data) to mpeg4 isn't perfect, and to recompress again (mpeg4 to mpeg4) is going to introduce a lot more artifacts and errors.

Humm... What standalone player is that? Me curious :D

[billharrison]

That is pretty much what I came up with. I was hoping to be able to drop the streams down, and not loose TOO much, because at the bitrate I have encoded now, there are almost NO artifacts or blocks, the video is ALMOST dvd quality (although I am not a stickler for perfection, and with tvout, it does kinda hide some small imperfections).

As far as everyone asking, the stand alone is home built, I used a Spacewalker motherboard (P3, Flex-atx SIZE, on board EVERYTHING including TV out), and right now am running Linux on it. It is in an old DVD player case I picked up at the goodwill store, so it looks stock, and will play dvd's because i have a dvd-rom in her. Right now I am coding a new OS for it that will boot off the hard drive, and support multiple file types, be flash upgradeable, out to lcd, (right now i have the lcd working in linux, but still too long too boot ~ 25 seconds), remote support, all the goodies ;)

I know someone posted a so called DIVX OS on here previously, but it was installed over windows! I don't think a proper os requires you too boot into another os!

I guess the point is that we need something for stand alone players that boots FAST (5-10 seconds) and is upgradeable to the newer formats, as DIVX is still quickly changing.

yes, this is the theory, and i agree with that. but i've already reencoded many 2cd divx3 movies into 1cd ogm with ~70 kbit sound. and the quality remained well over the line of enjoyability for me. on tv...
