9 hours to encode 1 hour of DVD?

[ashsharma]

I'm using Tmpgenc (the trial version) to convert a divx file to DVD. The film is only 1 hour long (1st disk). I'm using VBR 2-pass (i know this increases the time) and the fast motion estimate option.

But it's taken tmpgenc 9 hours to do this 1 hour of film!
Is that normal? I'm using a 2.66Ghz P4 and got nothing else running. Any ideas on how to speed it up, or is this the faster it'll be? Or should I use tmpgenc plus instead?

Are you using any filters?That will really slow things down.

[ashsharma]

what kind of filters? like noise reduction? No i'm not, I pretty much followed the guide from this site the only thing I changed was to make it VBR.

[johns0]

Somethings slowing down your encode,it takes me about 3 hours and 15 minutes to do the same as you with ivtc set,anything else running in the background such as a virus scanner slowing it down?

[ashsharma]

yeah I've got my Norton internet security running, but that doesn't take up too much cpu.
Is the trial version slower than tmpgenc plus?

[ashsharma]

After searching through a few topics I've read that different versions of Tmpgenc encode at different speeds. Does anyone know the quickest?

Tmpgenc has 2 versions of 2-pass VBR, known as old-type and normal. The old-type IS much slower and I am not sure if the newer 'normal' type is available in the free (trial) version.

[ashsharma]

ok that makes sense. it only gives you the 'old type' option on the trial version.

Last night I did a 93 minute 640x480 25 fps conversion to 720x576, 2 pass VBR (and mp3 to mp2, but that's a negligable amount of time). It took 7 hours and 32 minutes with slow search precision, no filters, and not the 'old' method.

It took 3 hours as CBR by way of reference. Resizing can greatly increase the time required(depends on how you re-size).

Mine takes between 50 minutes and two hours, I always set bitrate to 8000bps max and 4000bps lowest. My average DVD size is 3.3Gb.

I have a P4 2.4Ghz CPU, 1 Gb 266mhz DDR Ram, 2 x 7200rpm 133 ATA HD's and XP Pro.

Machine spec is very important, as with setting up the right bits in a TMPGEnc template. Mine used to take anywhere from 3.5 hours to 11 hours before I set the template up correctly. Unless you have a really old machine, running things like antivirus and firewall won't make a shags bit of difference.

Using 2-pass VBR?

[musotechy]

Nop, Constant bitrate and have yet to see the difference in quality.

The problem 2 pass variable bit rate, is that 50% of the time is spent on analyzing and the other 50% is spent encoding it. Which still means around 3.5 hours spent on encoding, which for me, is far to much time to spend on a file that has been pretty much spoilt by encoding it with DIVX.

So where do Max and Min come into it if using Constant Bitrate. You sure you dont mean CQ mode.

[musotechy]

Well spotted yes that's the one.


Thanks
