Encoding times

[shrink0]

Hey jdobbs or any other experts, What settings do you recommend to improve encode time. I'm using DVDRB pro, HCencoder ,Quality=best, mainmovie only. I'm getting approx. 5-6 hrs process times ,i know the free HCenc. has alot to do with it ,but other than buying new HW, what can I do?
Did ask this same ? over at Ddigest's forum , someone mentioned changing the rebuilder ini file Encode_processes=1 to ? so hope I'm making sense!! TIA

[therat]

A lot will depend on your system. What aree your system specs?

I can use DVD-RB Pro with HC set to best and do a full backup of The Godfather in a touch over 2 hours (did it yesterday).

Bear in mind I am using multiple instances of HC on my E6600 system.

A lower spec system with a single instance of HC will take much longer.

cheers

You don't have to edit rebuilder.ini, you can enable Multiple Encoder Processes from the Settings menu within DVD-RB. But this only works if you have multiple processors. To check, hit Ctr-Shift-Esc to bring up the Task Manager, click on the Performance tab. If you have 2 CPU History graphs then you have 2 processors/2 cores/or a Pentium 4 with Hyperthreading enabled to emulate 2 cores. Using multiple instances of HC with the first two situations will give you a significant boost in encode time. I think a P4 w/HT enabled could see minor improvement (10%).

That explains it of course! my specs are rather slow on my work pc for encoding. 2600+ athy 64 ,768 Ram . I let the process do it's thing at night so no prob. However I 've just installed DVDRB pro on my Media pc 3700 Athy64, Epox 939 mobo 1 gig Ram, 200g hdd,80 gig hdd,hauppauge 150. Just did my Saving private Ryan main movie only ,HCencoder, quality= best in 281 min. prepare/encode/ rebuild. I'm happy and the results are great. :thanks:

Or try with HCenc "Quality=Normal", the quality still remains good and you will not notice the difference on a CRT but the encoding time is reduced considerably.

@wmansir
I heard mine doesn't have *true* multiple processors. For example in picture one, it has for the 'cores' section, 1. When I use multiple processors (with HCenc) I get well under real time (PAL), about 10-15fps. Even using one HCenc I get around real time. Takes me about 6 hours to do a movie, no filters, single HCenc.

Does this sound right?

[therat]

Yours is a P4 with hyperthreading so it doesn't have 2 separate cores but instead emulates 2 cores. As wmansir said, using 2 instances of HC will only see ~10% decrease in time taken.

6 hours sounds about right for your system especially if you take shrink0's times as a guide.

cheers

[wmansir]

You have a P4 with Hyperthreading. HT isn't always predictable, this thread (http://forum.doom9.org/showthread.php?t=107248) indicates multiple instances of HCenc with a CPU much like yours is about 10% faster overall.

However, depending on the system it is possible that running multiple instances causes a bottleneck somewhere else and so the total speed is actually slower than one instance. See the thread linked above for more info.

Thanks tech! I was going to try the Normal setting ,except I was concerned about quality loss. I have a plasma hdtv. I Will give it a shot though and see how it looks.
Also side note to linx05 post, I did King Kong last night,same settings Hcencode,quality>best ,main movie only, total time 6hrs.52min. As i said processed at night so thats ok!!!!!

BTW I ran King Kong on my 2600+ Athy 64 754 skt not the 3700+ skt 939 sys. I should see better results on the 3700....

What is your system specs, thats sounds unrealistic to me, whats your setting, best in HC?

I have am2 4200 dual core, with 1 gig ram, it took 281min, one click from start to finish with multiple encoder instances.

the video was 4 hrs 30min however so maybe thats why, it was also interlaced.

I was using multiple instances of HC set to Best Quality. My copy of The Godfather is Region 4 PAL and I only backed up the first Disc which doesn't have any extras.

I did King Kong last night,same settings Hcencode,quality>best ,main movie only,


OT, King kong gives a compression of appx 50% which is too low, you should also try AQMenc with QmatOp for this movie for better results.

I've never tried AQM before so I have it a go on The Godfather. Compression of 52%. Not sure what I'm doing wrong but I thought both copies done by HC and CCE were better. HC and CCE were very similar quality

BTW with CCE I use the AutoQ2 matrix for low bitrate movies like The Godfather etc

[techreactor]

did you enable QmatOp, it will determine the optimum matrix to be used and then use it , for each segment.

Thanks TR! I just did Lord of War using HCenc "Quality=Normal, however I slightly OC'ed my 3700 A64 to 2.5 GHZ. The quality looks pretty darn good on the Normal setting. Going back to stock MHZ since I was just trying the Normal quality as fast as possible to compare times. Thanks again!!!!!!:D

No I didn't use any filters.

What's KK?

BTW AutoQMatEnc takes longer than CCE & HC. 158 mins -v- 113 mins.

[techreactor]

Well the BR are decent enough, no need to use QmatOp with these. HC would be faster than AQM under these BR's since the crux of using AQM is with low BR's and yes, QmatOp does add a considerable time to the encode.

KK is king kong, it was nearing 51% compression but with lower avg bitrates than 2k.

[therat]

Fair enough. The Godfather is a much older movie without the special effects and action sequences of modern day movies, so that would explain the bitrates.

[gizzin]

I didn't realize how good your processor was therat. But it makes sense now. I really wish I never bought a asus board they are really sh*tty.
