Why split the audio with Flask then re-encode it ?

The simple answer is so that you can edit the video in whatever way you want (eg. Increase volume, change to MP3 track of a desired bitrate, etc.). Also, in my experience, letting Flask encode the audio often results in rather unsatisfactory audio quality (I can't quite explain what I'm hearing here). Also, Flask does not seem able to quite perfectly extract DVD audio. The audio very often needs dynamic compression. My method of using Graphedit and then editing it in various ways until I get an MP3 soundtrack of a desired quality works well enough for me.

Nandub getting old in the tooth? It still works better than the younger generation of Virtualdubs in terms of quality and encoding control.

U can say that again my friend Enchanter, I agree with you!

I have a question for you Enchanter:

I am a fast motion lover (codec) It gives me NEAR DVD quality results (Hard to believe I know, I have broken the "world record" for this)

If I use nandub and set the file size to, let's say, 13MB for 3 and a half min video and audio = 128 44100Hz MP3.

In the SBC settings, the "switch FM dll..." is set to 200 and the rest is left alone. I choose MSMPEG4 v2 and do a 2pass. Ok it works, but the quality is shocking!

If I do the same thing but with fast motion, the quality is 20 times better!

Why is this? I thought Nandub was suppose to improve the quality than fast motion in a 2pass? HELP!

If you want to tell Nandub to use FM all the time, just set both sliders all the way to the left.

Here's an extract from Doom9's guide:
The main difference between DivX Low motion and DivX Fast motion is the hardcoded compression settings. Fast Motion basically has a hardcoded DRF minimum of 7 and goes up till 16 whereas Low motion can go up till 2. Fast motion might be a bit better at motion detection but the difference is hardly notable. So in fact you can safely set the Fast Motion slider to 300 and only work with the DRF settings. Or for instance you could use DRF 7-16 for motion over 280 which achieves the same as having the motion switch (from Low Motion to Fast Motion) at 280 in the motion detection box.

p.s. I basically use 2-8 for my min/max DRF settings, sometimes a different one just for the sake of wanting to do it.

Thanks for that! It is greatly appreciated!

But what I am really asking is that, why is fast motion better than low motion when doing a 2pass in nandub?

[Enchanter]

I don't use FM anyway. I try to preserve as much detail as possible.

As to which is better, it's a very subjective question, though most would agree that low-motion is better because it does not discard too much details compared to fast-motion. But if you really find that fast-motion is better, then use it. There is freedom of speech and choice after all.

[techno]

I do agree that low motion is better! No doubt but the way I do my vids, fast motion is just the same as low motion, in terms of detial and lower file size which is great for me!

Thanks Enchanter!

Enchanter,

I just did The Phantom Menace on 1 CD using DivX 5.0 Pro 2-pass mode (w/ 128 Mp3 audio) and it doesnt look half bad, even on the fast scenes (i.e. the pod racing scene). I set the bitrate at about 582 with a resolution of 640x272. Give her a wirl, its not too too bad at all.

--bzhk

Yup. This movie turns out to be very easy to encode and compress really. I actually used a bitrate of 550 only and a resolution of 544x224. Too high a resolution often leads to noise and picture warming, which really is bad. In my case, the video was clean and macroblocks were not found anywhere in the rip.

p.s. The highest usage of bitrate is the battle scene between the droid army and the 'whatever-lizard-like' creatures, especially when they have just physically entered the shield dome. The racing scenes, in contrast, don't use that much bitrate and require probably only a quarter or half of that for the battle scenes.

You can up the volume etc with the the audio already encoded with the video, well I've never had any trouble. If I want to save the audio seperate, I really would not use Flask for the job. I'd use something like DVD2AVI myself.

But then again I do loads of things that others may not and so many people have sync probs when muxing the audio and video at a later stage. I've just been lucky and never had sync problems, so I'll stick to this way for now.

[Enchanter]

Was there a discussion regarding the audio in this thread before? What exactly do you mean?

I usually use Cooledit or Virtualdub to get my audio jobs done anyway.

Ahh, right. Must be the lack of sleep because of yesterday's work. Can't think straight.

[Ndb]

I know how you feel

[techno]

Tell me about it!

BTW

does anyone know where I can download ALI the movie on VCD?

I can't find it on imesh, or grokester or kazaa

any ideas?

I use LimeWire, so will get worse than you. (I use LW because I like to keep my FireWall on)
