36 hours to convert avi to mpg? Is that for real?

[ip]

Hey guys, hust found thiis site-great stuff.

I tried converting an avi full-length movie to a mpg using TMPGEnc so that I can watch it on a DVD player but it showed that it would take 36 hourse to complete the conversion. Obviously I thought it was an error. Was I wrong, is that really how long it takes?

TIA.

Believe it... my record conversion time is 90 hours...
I have a P3 500, an average DVD -> XVCD takes it around 30 hours when I use the highest quality setting (higher quality = slower encoding).
Its just something that you learn to live with.

[ip]

Holy s*&^%! I guess that's why it says "crazy fool" under your monikers .

Does the conversion to mpg change the size of the file?

thanks again.

I think if you split the AVI(DivX) Audio part into a seperate WAV file, and select that as the Audio Input, it will speed up the encoding time.

[devinemi83]

yup sadly thats true, the higher quality you want the more time it going to take. I have a 500MHz celeron and I capture from vhs into high quality divx then convert and mine says it will take from 3.5 to 4 times the length of the video to mpeg encode.One thing I hear people talking about is getting another 500 meg machine and using it just for the processing and using a more powerful one for other uses that way your machine isnt always in use,And with todays prices you could get a machine like that for less than a couple hundred.
I mean after all dell sells a 1.7 gHz I believe for 799.00!!

Just as a thought. Is there a quality loss if you: vdub>>frameserve>>tmpg/lsx/cce??

It's been awhile since I've done it, but I know it's definitely faster...maybe 5hours to complete.

Like I said, just a thought cause I keep reading ppl always complaining about how long it takes.

[pinoy2201]

realy damn.... it takes me 4 hours on the highest settings ..damn i only hav a P3 1.0GHz

[tigerwolf]

Sefy is correct, many times if you rip the wav out and use the wav file as your audio input it speeds up the encoding considerably. I'm guessing the divx format does some freaky stuff with the sound. Though I've had some divx movies that didn't require me to extract the audio into a wav. I've started making it a habit to do so.

I am starting to become a bit curious on what is different. On highest quality with tmpgenc, the longest it has taken for a 2 hour movie is about 20 something hours, and I'm running a p3-450mhz. Yet I see things like "crazy fool"
with much longer times and a comparable system at least processor wise.

i have an AMD900 with 256mgs. i just did some clips earlier and it takes me about 3 hours for a 12 min clip. highest settings and at 1700cbr bitrate.

[TPW]

usually takes me 4 hours on my 1 ghz machine with 384 MB of RAM, it helps if the audio is wav a bit, but not by much on my machine. I only convert to wav when the encoder cannot read the audio in the video file

For what it's worth. . .
Just finished doing one of my many test this late night with the
Hauppage WinTV PCI card. . . .

For a 7min (12,851 frames) AVI capture...
It took 27minutes to encode.
So, for an average of 7min clips * 6 = 42mins total would be (27min * 6)=2.7hrs for
a 1 hour tv show. That's just a guess.

The above was ENCODED with:
TMPGenc @ 1850min/2520max/128kAudio/352x480res./NarmalQuality

SYSTEM SPEC:
AMD T-BRD 900mhz, w/ pc133 128mb ram

Thanks for the tips.

Can someone let me know how to get the sound out into it's own wav file? I'll try that and see how it goes.

[tigerwolf]

virtual dub works nicely to extract the wave

[ip]

Thanks. Virtualdub did work well to extract the wav. And TMPGEnc did make the conversion to mpg much faster that way (10.5 hours).

However, 2 big problems came up:
1) The sound is now about 3-4 seconds behind the video. Why? Fixable?

2) The conversion to mpg increased the size of the movie to over 1 gig, so it now can't fit on a CD-R. Any way to get it under 700 MB?

Thanks.

No, now you need to break it into two files so it will fit on two CD's. I use TMPGEnc to split it, overlap where you cut the first video and start the second by 10 - 20 seconds that way you can be sure your not missing any scenes. I just plop them into a multi-disk player in order and you only have a couple second delay when the one ends and the new one starts.

lol
on my ol' PII 350 256mb it takes about 6 days to do a 2 hour movie MPEG2 720x576 2500kbit cbr highest quality, floating point DCT. as u can imagine, i don't encode whole movies like this. only short clips such as music videos.

resolution makes a HUGE difference though. vcds at 352x288 are WAAAAYYYY faster. but it's still far slower than real time.

i was thinking of getting a new cpu, but i realised that even if i got a p4 2ghz the setting at the top still wouldn't encode in real time. so i'll wait a little until more kick ass cpus come out.

does anyopne know how much dual cpu speeds up the encoding? double? more than double?

Ok, that would be fine. Looking around TMPGEnc, I don't see a "split file" option. How do you do it? Also, what about the sound/video discrepency?

[staind_96]

click on file and go to mpg tools. then merge and cut.add the file you are going to split, double click and choose where you wanna split it.

Thanks. And the sound/vid discrepency?

I promise, I'm coming close to my last question.

" Yet I see things like "crazy fool"

I use all the slowest settings and I encode to XVCD.... Oh yeah, whilst multitasking other apps.

I recently bought myself a shiny new 256MB-CAS2 RAM module, I dont know how much this will speed things up (not by much I think).

[sommersby]

Just to add, when you use the mpeg tools in tpmpeg, make sure you select vcd or vcd (nonstandard) as your output file type, other wise you will end up with a non-usable, (for vcd), file!

[sommersby]

The only real solution is to go to a faster machine, low prices make it very appealing right now, to do a full dvd rip and conversion on my 1g athlon takes approx 4-5 hours, with the new 1600xp athlon that improves to 2-3 hours. And a bare bones system with the xp runs about $250 on ebay and around $200 at computer shows!
