HB: 12 hrs encode one movie - is it normal?

I am encoding 2hr 45 minutes movie with AppleTV present with
3000 bit rate , 2 pass (turbo) setting. It took almost 12 hours to complete
the encoding. Is it normal?

I started at around 8pm yesterday night and let it run over night and
in the morning it is still not finished at 8am.

So, I wonder if you it is normal time for HB?
 
I don't see a single mention of what kind of hardware you're using. Would you please tell us the specifications of the computer? Was it directly off the DVD or from a hard drive?

On a Mac Pro 2.66 quad, 5g ram, I can encode a 2 hour movie around 45 minutes on the default AppleTV present, which is I think 2500 bitrate and single pass encoding, H264. Average around 60fps.

Are you running this off a Gameboy?
 
On my MBP, using handbrake to rip and encode a DVD of about 2 hours length takes about 2 hours (2.16GHz, 2GB ram, 200GB 7200rpm HD)

My PC is what I use, and I get the same results as Sean Dempsey. My PC specs, C2Q Q6600 2.4Ghz, 4GB DDR800, Raptor X 150GB HD.

This is all using the standard HB preset for HB, but even with the slightly higher bitrate of 3000 that you are using and two pass with turbo first pass, 12 hours is long for an Intel mac.

If its not Intel, then, lets say its time for an upgrade ;)
 
i was excited about HB until i tried it with 2 films. It took forever on my imac G5. Many many hours. Even left it on overnight and while at work and still was not done

Aha! More evidence OP is using a G5. Could be a MP though. I don't think even the slowest core duo machine would encode that slow though but maybe with those presets. hmmm.
 
Sorry - I was away from the computer for a while.

My computer specs are iMac intel core duo 2GHz, 1.5GB ram.

It's my mistake that I over looked on my HB version. I am actually running HB built from the source code as of April 8th. It may have some bugs as I am using bleeding edge.

I will try with making new image from fresh start but I definitely haven't seen any thing less than few hours to encode for 2 hrs of movie.

Just download the packaged version... there's no benefit to "bleeding edge". Since when was bleeding good? Go see a doctor.

And then try it with the normal version. I encoded a 2:20 movie on my core2duo 2.4ghz imac with 4gigs of ram and it took maybe 1:30.
 
12 hours at those settings is about normal for my iBook.

God I need an Intel Mac...

EDIT - I just saw that you used 2 pass encoding... 12 hours would be fast on my iBook, more like 18-24 hours for a movie at really HQ settings at 2 pass. That's why I use the OctoMac at work to my heavy lifting.
 
Consider yourself lucky if you haven't seen any audio to video sync issues with HB 0.9.2 (with 5.1 audio). I have lots of international movies and some hollywood movies which have 2 to 3 secs delay in audio to video in mp4 encoding.

This issue has been reported to HB forums and they seems to have fix in their development branch. This is the reason I am using bleeding edge.

I bought an Apple TV yesterday, fantastic bit of kit!

Encoding a DVD on my Mac Pro takes 20 mins using the standard Apple TV preset in Hand Brake. I love my Mac Pro!

Yeah Mac Pros are incredible for this stuff. The 8 core ones just fly.

HB utilises multiple cores?? i know it maxes out on my MBP, so i spose that it would on the octo.

Pretty sure it uses at least two, all I know is that our 2.8GHz Mac Pro is almost exactly 2x faster than our old 2.66GHz Mac Pro at the same settings.

So freaking fast.
 
HB uses all 8 cores, although doesnt max any of them out, so when converting movies it uses 70% processing power, which I like because it means you can use the computer as if it wasnt doing anything else.

WHAT!!!!!!!!!

youve had more than 1 MP!!?!?!? hhmmm so jealous. lovely to hear that the MP screams... *dreams away*

aahh ok thanks for that. i think its good that they only make it utilise 70%, leaves plently of other power for the other things ;)

BTW - Try encoding with CRF at 65%-70%. I find that the results look better (more consistent) and is faster due to being single pass.
The downside is that the size is not predictable. Some older movies result in freakishly large files since it tries to preserve all of the blurriness and flaws.
 
HB's use of cores depends on the optimization of the encoder you select. The most optimized is x264 (which is pretty much the main encoder for any Apple Device including the ATV). Also realize that the deinterlacer is not multithreaded so will slow up your encodes a fair amount if used.
 
Mac Pro 2.66GHz, 6GB RAM - I don't think I've ever had a Handbrake encode take much longer than 30 minutes. Most are around 20 minutes (Apple TV preset on HB but with AAC+AC3 audio instead). Even cramming things down to an iPhone friendly 750Kbps are done in far less than 1 hour.
 
on my mbp i get around 90fps, so you should be averaging somewhere around 60-70>?< i have no idea why its using less and i would recommend you to stop using the source code and download the latest version!!

on another note

pretty jealous aye that machine is a dream. mind you my CD mbp can rip in around an hour, so im not THAT jealous ;) (NOT).

how many FPS are people averaging?
 
jaglad said:
Cant remember what FPS I am getting, but when encoding a DVD to my iPhone, it takes 12 mins!

yea well you have a 3.2ghz octo in raid... you bastard! lol...

that is so unfair. can you like host a core for me??? hahaha...

thats a beast. im SO jealous. how do u afford that lol?
 
Yes it is a awsome machine to use!

The only way I can afford it is by using the time honoured tradition of working hard for a living. I dont use the computer to make me money, it is purely used for pleasure. :)
