ConvertXtoDVD: High and Real time priorities

[alc112]

Hi!!

I was wondering this since two days ago while enconding some AVIs

well, I always use Realtime priority because, as far as I know, it's the fastest way to make a DVD.

But this days i'm enocnding 18 Avis in one DVD and each avi has 21-22 minutes.
The process was about 4 hours and a half.

Maybe this mean that if an avi has 21 minutes, then the enconding will last 21 minutes??

So for this case it would be batter to select high priority??

I hope I've been clear.

Thanks a lot

If your machine is doing nothing but encoding, altering the priority will have little real impact. The priorities are there to determine which processes get more CPU time, and if you are the only thing running, you are getting most of it anyway. You are encoding over 6 and half hours worth of footage in 4 and a half hours. That is better than realtime, and probably about as good as you will get on your system.

FWIW, personally I believe that is about twice as much as should be put on a single disc. ConvertXtoDVD doesn't do VCD or half-D1, so if you are going for a single layer disc, it will be a very low bitrate, and on a dual layer disc, still around 2 and half hours too much.

Thanks
What I'm encoding is Robotech serie and as it's from 80's, the quality is quite poor so it's enough.

When I'm encoding movies, I put one in one DVD.

The next time i'll encode more of that, I'll try High Priority. Maybe it's the same... who knows...

Thanks so much for the answer

I don't use ConvertXtoDVD but I usually run encoding software at idle priority -- the lowest. That leaves the computer available for anything else I want to do. As guns1inger pointed out there is little difference in encoding time unless you are using a second CPU intensive task.

and how much time does a movie need in that situation to get ready??
I'm sure you are not hurried when doing that


A bit off topic:
I forgot to copy the cover before start encoding. so when I remembered, I came to the computer, select the file (luckly it was in the desktop) press crtol+c and then plugged a pendrive in.
The process of copying the cover lasted about 15 minutes!!

Maybe 1 percent longer than running the same conversion at a high priority.

The other thing to look at is just how much CPU is being used when ConvertXtoDVD is running normally. You should find it spends a lot of time at around 100%. If all the CPU is being used then changing the priority won't give you any extra. Contrary to some films, you cannot go to 105% on the reactor when using a PC.

hi again!

Today I tried with 12 avis (21 minuetes each one) in normal priority and the process lasted 3 hours!!

So,it was like you said. all depends on what are you doing in the Pc, you aren't doing anything, then the conversion will be faster.

thanks a lot

What you are adjusting the the scheduling priority. When more than on process wants the CPU the one with the higher priority gets it. But when only one process wants the CPU it gets it all the time.

I use convertX and i leave the priority LOW, this way if i need to do something else, the PC might actually respond to my commands

normaly when i start an encode, i walk away and do something else, OR i start it before i goto bed, or leaving the home
