convertion took 3.5 hours. why?

[GangstaRap]

I used DIKO to convert AVI file to DVD and i took like 3.5 hours!
the audio convertion itself took 1.5 hour! (i also used Sonic Foundry Softencode too...)

is it normal? how can i encode faster with this tool (DIKO)?

ThanX!!!

On your system, ConvertXtoDVD would take around an hour to convert a standard length film. The issue is really one of quality. What video encoder are you using with DIKO ?

guns1inger, thanks again for the help man

yes, i know, i used to encode with it and conversion took only half an' hour but as you know well it caused me the overscan issue and i chose to avoid it.

What video encoder are you using with DIKO ?

i'm using HCenc_020 for the video.
and Sonic Foundry Soft Encode for the audio.

thanks again! your'e the great...

On my system, HCEnc encodes in around realtime (25 - 26 fps for full-D1) and CCE encodes at around 50% faster again (around 37-39 fps) when being fed from an avisynth script. That is going from one drive to another. I haven't used softencode in a very long time, but I do remember it being pretty slow - although 1.5 hours seems excessive.

So over all, for a 2 pass encode, those numbers are not far out of line. Programs like ConvertXtoDVD, even though the use ffmpeg, which is capable of good results, are tuned primarily for speed and convenience. They could wring much better quality out of ffmpeg, but it would come at a cost of a more complicated interface and a slower encoding time.

When you choose to play with the next tier up, you find that they do take longer, but the quality difference on good source is substantial.

But like I said, for what you are using, those numbers seem about right.

guns1inger, OK man thanks.
i'll try to use other video encoder with DIKO or something.

No good encoders are fast. This is not a reflection on the encoder, simply a statement that good quality processing takes time. CCE is still the reigning speed king in the top tier encoders. Nothing comes close most of the time.

as well as the quality
Though HCEnc is also pretty same in terms of quality, but alas not in terms of speed.

[guns1inger]

Horses for courses. CCE at 3+1 passes is good for DVD reduction, especially on action films, or grainy, treated footage, but I prefer ProCoder for DV source or DVD reduction where the images are more colourful and cleaner.

That said, HCEnc is coming along in leaps and bounds, and for a freebie it is difficult to fault.

You mean setting the number of passes to 3 after choosing Multipass VBR- right? Because if I understand correctly, a setting 2 passes in CCE makes it go for 2+1.

[guns1inger]

CCE always goes one more than the number of passes selected, as it doesn't count the analysis pass in that number.

Someone told me that lowering the resolution will increase the convertion speed...
but what really bothers me is the audio convertion - who took 1.5 hour.

is there any possibility to make a Direct Stream Copy to audio with DIKO?

and thanks again for your help!

[guns1inger]

You may as well learn to do it by hand.

[src2206]

If you are interested to make a Direct Stream Copy then use VirtualDub, it is lot more easier and faster. Moreover I do not think that in DIKO you have this feature.

OK ThanQ guys i'll try it.
