DivX Pro 5.20 to MPG2 - sloooooow?

[sdsumike619]

I am trying to convert a DivX movie to MPG2 to put on a DVD.
My CPU is only an AMD Athlon 1800xp, but, when I encode in Vegas from the DivX movie to MPG2, it goes painfully slow - estimates about 22 hours for an hour and a half long movie..

I noticed however, that if I encode the DivX to DV and then encode the DV avi to MPG2, it goes the right speed (fast!)

Is there some issue with going from DivX to MPG2? It seems like in the past I've done the same thing and it only took about 4 hours...but now takes forever..

I would never use Vegas to process Divx source. While it can do it, there are too many issues to make it worthwhile. If Vegas is the only encoder you have then I would look at HCenc as a possible standalone alternative. Install HCenc, avisynth and fitcd. Use Fitcd to create an AVS script to resize your Divx source. Load this into HCenc to get your mpeg-2 video stream. Faster, less hassle.

If your Divx source is reasonable to good quality, take a look at the free version of DivxtoDVD. It should process your 90 minute file in around 60 - 80 minutes on your machine.

you never said what settings, effects, compositions, etc you are using in vegas -- to even make a meaningful guess .. yes , vegas is NLE and composition tool, not just used for encoding .. if you bought it for only that purpose, from xvid/divx source, what a waste of money .. as xvid /divx are not supposed to be used for editing anyway ...

haha, no it's not all i use it for, you've helped me a bunch of times before, I produce instructional DVDs, this was just something I had that I wanted to put on DVD that wasn't DV to begin with... it worked out well to convert the divx to DV with virtual dub and then encode the DV to mpg2, saved a lot of time !

[BJ_M]

ok - sorry ..

to speed it -- also you can frame serve it from vegas to avisynth or v-dub ..

i personally would not convert something to DV if I did not have to because the DV to mpeg2 conversion isnt the best thing in the world (no mater what app) , specially if there is text ..

but your work flow is ok --- and will really speed things up also .



If you have the room - i would use huffyuv instead -- also , do any resizing BEFORE bringing into vegas to really speed things up ...

[sdsumike619]

why would frame serving speed it up? doesn't that usually slow things down? frame serve the divx from vegas for what purpose?

[BJ_M]

im going back to bed -- i thought you were encoding to divx .... so never mind that part ...

but the following still holds

"i personally would not convert something to DV if I did not have to because the DV to mpeg2 conversion isnt the best thing in the world (no mater what app) , specially if there is text ..

Wow, i got that DivX to DVD software, it's not even expensive and this thing encodes FAST, WAY faster than Vegas - how can it be so cheap and work so incredibly fast?

BJ_M, you were right, the m2v file sucked that Vegas rendered from DV, even though it was fast, but this VSO DivX to DVD is really nice!

What is huffyuv ??? What does that do?

[BJ_M]

huffyuv is a codec used for intermediate file that work well in vegas ..

[sdsumike619]

"huffyuv is a codec used for intermediate file that work well in vegas .."

but what type of file does it produce? what do you mean by "intermediate file"

is it avi?

Also, I'd like to know how DivX to DVD encodes so incredibly fast compared to Vegas's MainConcept encoder? and it's only $30!! Going from DivX to MPG2 in Vegas was saying 22 hours,, VSO's software did it in about a quarter of that time, not only that, but it created the DVD compliant files all in one step.....

What am I missing here haha

[BJ_M]

vegas does not use mainconcept encoder to encode to divx ..

vegas to divx is also fast - but you prob, have a filter or level change going on there - or picked 'best' as quality .. vegas is not made just for encoding but does a lot more ..

VSO software is only basic encode only i suppose .

[sdsumike619]

no no, I meant encoding FROM divx to mpg2 in Vegas was more than 4 times as long as in the VSO software. and I didn't have any filters, and my quality is set on "good"
All I really did was slap it onto the timeline, picked my encode settings and that was it, and it was saying about 22 hours in Vegas - and I could see that it weas doing about one or two frames per second.
That vso software, on my crappy computer, just sped right by, and did everything including make the DVD (without any menu) in a couple hours,,, really very amazing!

So what about the huffyuv, is it for avi or mpg or what?

[BJ_M]

well something it wacked in your decoding of divx in vegas .. also it is going to go through a rgb conversion .. should not be that slow though - something is not right ..

since there are several options in vegas to decode divx , you might want to try another codec (xvid, ffdshow, another version of divx, etc )


huffyuv is for making avi lossless files - it is a good free codec
