The complete HD (Blu-ray/HD-DVD) back-up thread.

Thanks Ryu, and sorry to bother you with my stupid Qs.

oh I thought the above search is for google only lol

Wow.. a little frustrated today. Been making beautiful backups of my blu-rays on my HTPC for a couple months now, and VERY happy with the results. Decided to go ahead and update megui, and BOOM.. everything came to a screeching halt.. from 16-18fps down to 1..

went ahead and read the updates on the forum, realized that x264 has undergone some changes, so downloaded the new package, made the necessary path changes, and first pass is still at 9fps.

Also saw Ryu, ya made some changes, as my bitrates were at 12k, and now they're defaulted at 18k

Is there anything I can do to get back the speed? or is this the result of "progress?" I have also read that the new 264 doesn't produce as nice results as the previous version.. ( i was running 1183)

 

That bitrate is there simply as an example. Please follow the method I stated earlier to calculate the bitrate required to meet your target...

If you are using HD audio, then you will need to mux that by itself into a M2TS container and then allow 5% for the remaining video stream.

What is your target? DVD-9 or BD-25?

Also, where did you hear that the new x264 is inferior? I have heard good things about it and have had good results. If you want the speed back, disable MB-Tree.

 

Basically, I didn't really have a "target" size. I used it for smaller file sized mkv's on my HTPC. Here was my process.. I rip my collection with AnyDVD HD, extract the movie stream and audio, got the avs script then ran your "blu-ray ultra high" profile. (started with insane quality, but didn't see much difference to justify the encoding time difference) When the encode was done, the mkv went from, say 27gb to maybe 12 or so. I encoded the audio and muxed to mkv again.

Each encode took roughly 8 hours for both passes, first pass was 15-18fps, second ran about half that.

As far as the new build for x264 being inferior, I read further into the posts and found it may have been that individual's settings.

Either way, I'm simply looking for backing up on internal HDD's, not BD's. I have continued to try different settings, but to no avail. Kindly provide me some direction. I appreciate it!

 

heynow12, it might not be a bad idea to have a set target in mind and use the bitrate calculator to reach that. If you're storing on a HDD, maybe work out how many movies you would like to store on each HDD and go from there. If you have plenty of storage you could always use tsMuxeR to remux the main movie and primary audio track only, leaving you with a file size of 20GB to 30GB with no re-encoding at all.

If you want to go back to using 12,000Kbs, then feel free to change that setting.

As mentioned above, the only speed adjustment setting that would have major impace compared to my previous aet of profiles is MB-Tree. You could try disabling it.

 

looking at the command line, I also see theres a lot of new goodies that I'm apparently not aware of .. Here's what they look like.


Original (quick, fine)
"C:\Program Files\megui\tools\x264\x264.exe" --profile high --preset fast --pass 1 --bitrate 12000 --stats "D:\OUTPUT" --thread-input --output NUL "D:\F1_T2_Video - .avs"

(new x264, slower)
"C:\Users\MEDIA\Desktop\megui\MeGUI\tools\x264\x264.exe" --profile high --preset fast --pass 1 --bitrate 18000 --stats "D:\OUTPUT" --thread-input --keyint 24 --min-keyint 1 --b-adapt 2 --b-pyramid strict --ref 4 --weightp 0 --qpmin 8 --vbv-bufsize 30000 --vbv-maxrate 40000 --rc-lookahead 24 --me umh --direct auto --subme 8 --partitions all --trellis 2 --no-dct-decimate --no-fast-pskip --aud --nal-hrd --mvrange 511 --sar 1:1 --output NUL "D:\F1_T2_Video - .avs"

Thanks again in advance!

 

When did I ever offer that first profile? That looks almost entirely comprised of default settings. I know with 100% certainty, that wasn't one of my profiles. If it was, then it has been majorly altered. No wonder you are seeing such a big speed difference.

 

Ryu77..

sorry, we mustve been replying at the same time..

I've tried disabling mbtree and lowering the bitrate both.. still, the speed is nowhere near where the old x264 used to be. based on the command lines I posted, maybe something else?

Would the latter produce better results regardless? Basically, should I just suck it up? heh

 

OK. That was a default profile using the prior x264 build. using the same default with the new one, it still is about 6fps slower during each pass.. Same process, same test file. Can I assume this is the way this is done now and just suck it up?

 

What is the default command line of the older build vs. the default command line of the newer build?

 

Hey Ryu i see you still hanging in there....I got a question about encode times...


My PC AMD Phenom 9750 Quad Core 2.40Gz & 4.0 Ram..Vista Business Service Pack 1.

What could i do to boost my speed ? I was thinking increasing the Ram to the Max 8GB.....Thxs

 

hey again Ryu.. Trying for a few days now to figure this out. no luck

I realized what I HAD been doing was, with the old version, the "advanced settings" checkbox was unchecked, so it used the defaults that I provided earlier, which was why I got the speeds i did. Adding the advanced settings dropped back down the speeds, regardless of the versions. Please forgive my previous questions.

However, Isn't 1.5fps still insanely slow for a 2nd pass? Could this possibly be a product of running and AMD chipset? Ive got a nice little X2 550 with plenty of RAM, but this seems to be pinning my CPU as it's set up. And 36-40 hours seems a bit excessive to encode a movie.

Would you have any thoughts? recommendations? I appreciate it in advance. Thanks!

edit: also tested on my XP laptop, an intel chipset, and pretty much same results

 

Well, it is still a dual core so you can only push so much through its pipeline. The biggest influence with x264 encoding is CPU power. RAM makes minimal difference provided you have enough.

A quad core CPU will more than halve your encoding time. I would guess that the new hyper threaded quad core i7 (8 processing threads) lineup should make things even quicker. At this point I am running a Q6600 OC'd to 3.2GHz and I usually encode a 1080p movie in about 10 - 16 hours depending on the duration of the video.

 

Wow.. seriously? I just put together this rig specifically for this. with an i7, i'd have to buy everything new, new chip, board, ram.. errr. don't have the extra scratch for that.

I guess I can just go back to the stripped down defaults I was running before. They seem fine, unless there is a real reason not to? Quality of the result still looks pretty damn good I thought.

 

You don't need to go all out to an i7 setup. As mentioned I still get very quick results on a OC'd Q6600 Quad Core (Socket 775).

 

true.

i may also get another board and unlock the other 2 cores on the 550. one of the reasons i went with this chip. see how it rolls. i appreciate ur help pal.

 

Hi, I have (what I believe to be) Ryu's latest MeGUI package. It wants to update a bunch of things including x264 and MeGUI core (from 3.1.1061 to 3.4ish). Is there any conflicts with this or should I just leave it alone? Thanks for the help.

 

hi, i am using the latest megui 0.3.4.0 ( that i am aware of lol ) i am recoding my video from m2ts to x264 using a mkv container. i am using the preset " bluray insane"

i have an i7 920 with 1066 ddr3 triple channel and it takes 3 hours to do the encode .

question:
1- what is the best encode setting to get the best quaity video as an end result? i don't care if it take 20- 30 hours ...just want the best quality .

thank you for any help you guys can give me.
