The Apple TV 3 only has a 100 Mbit Ethernet port, but that's still plenty even for streaming 1080p content. If you're using WLAN, maybe you're on a crowded channel or there's interference. Would also be interesting to know what you're streaming from. Under normal circumstances, buffering should only take a couple of seconds.

I'm planning to get a time capsule. I imagine that would help?

I'm using a 2011 Macbook Pro-- would it be helpful to connect it and/or the ATV 3 w/ethernet rather than using wifi?

Can't see how it would. The Time Capsule can't act as an iTunes server.

Most definitely. A wired connection, even at "just" 100 MBit, is nearly always faster and more reliable than wifi, even if it sounds slower on paper.

Oh wow, for some reason I thought it was 1gb. I'm sure 100Mbit is enough I guess (always been fast for me).

Depends on what you consider "significant". Visual quality expectation is entirely up to you.
The maths obviously say that quality at RF 21 is better than RF 22...
But first, will you ever notice? Depending on your display device, its size, resolution, settings, the distance between you and the screen, ...
And second, will you care? First instance, some people do a picture-by-picture side-by-side comparison and consider any discrepancy just unacceptable and therefore might choose RF 16 or even lower :shock: . Audiophiles with high end audio equipment will only accept DTSHD-MA while some other people will accept PAL sped-up audio re-encoded as Dolby Digital 640kbps. AFAIAC, I am quite picky about smoothness because I'm used to watching Blurays on my LCD which has a "24p" mode... So I do what it takes to manage motion judder (details in a separate thread for those who are interested).
So find whatever visual quality is "best" for you! Once you have defined the target, you'll have to choose how to reach it, mostly a trade-off between encode time and filesize.

My rips look great at the 22. I'm picky and have tried to find differences. I just can't see them.

Even at 22 it looks so much better than Apples 1080p, which even with better source material is so compressed bright skies and stuff look terrible.

I tried out your settings, and the results are great. Thanks so much for your help!

This is more of a Make MKV question, but you all are very knowledgeable here so I thought I'd ask-- is it best to select DD 3/2+1 within the audio settings for use with an apple tv 3? Does that setting include AAC & AC3? I don't believe apple tv's support TrueHD or DTS-HD audio (and, from my understanding, these are huge files). I am not running surround in our house-- just stereo. I suppose we could do 5.1 in the future though, so I'm imagine DD 3/2+1 would give us that option?

Hey M4dm0nk3y,

Which thread were you referring to that dealt with issues of micro stuttering/judder? Couldn't find via google or forum search.

For those who are using the customized settings I suggested earlier in the thread, just would like to let you know that I have been using 8 b-frames for a while now and it works really fine. So since 8 b-frames is what x264 --preset veryslow sets, I'll stick with that from now on.

I've used these settings on a couple of files and must say I love the results overall. Quick question I have though - what exactly (or even generally) would need to be changed if I were backing up an animated movie? I have a Disney collection I'd like to eventually back up for the kids and figured I might as well know what I need to be looking at. Thanks!

Also, to quickly chime in on the file size stuff going on in the iTunes store, go look at a movie like The Prestige... The 1080p is actually a smaller file than the 720p version (3.94GB vs. 4.20GB). They've obviously cooked up something pretty good on the compression side that I'd imagine could only be accomplished with the master source.

IIRC, The Prestige was full of very dark scenes. It would be interesting to see comparison screenshots of those in 720p and 1080p, particularly with regards to shadowy areas.

The higher compression of the store-bought 1080p files does come at a cost, even in cases where the 1080p versions aren't smaller than their 720p counterparts. There's certainly more color banding to be observed, along with a lack of grain and fine details. It's clear that there's more at work than just the "magic" of High Profile. They also made a conscious choice to further lower the quality in order to offer 1080p encodes that are only subtly larger (or in your example, even slightly smaller) than their 720p counterparts.

Firstly, please excuse my ignorance on this subject.

I've been encoding using the 'iPad' preset, with 'Width' changed to 1920 and 'Constant Quality' set to RF:22.
This produces a file that takes 30% longer to encode and is only 80% of the size of one created using the 'Normal' preset with 'Constant Quality' set to RF:20.

Can any of the more savvy people here tell me if this is Technically wrong?

Nothing wrong with it as long as you are happy.

However the ipad3 can handle more than the original ipad, thus people are using more advanced settings.

Yeah, I'd figure as much and I'm not about to buy it again in iTunes to find out (the BD is on sale at Best Buy for $8 if anyone's interested :) love that movie)... Either way, using m4dm0nk3y's settings (at 20.5 rf) and only including DD 3/2.1 passthrough and a PLII mixdown (basically like iTunes) produces superb results in a 5.2 GB file (just a ~GB bigger than iTunes' über-compressed version). The only drawback is a pretty slow encode... ~12hrs at an avg of ~4.6fps on a quad-core i5 with 16GB of RAM. But hey, we were warned.

Never mind... Found what I was looking for and more (including the genesis of your much more simply explained settings) here: viewtopic.php?f=6&t=19426

Hey all,
Was wondering if I could get your thoughts on something. I've been using the following settings for New iPad compatible encodes:
high profile + 4 ref frames at RF=20 plus the string below.

b-adapt=2:rc-lookahead=60:ref=4:direct=auto:me=umh:subq=10:merange=24:psy-rd=1.0,0.15:analyse=all:trellis=2:deblock=-1,-1

90% of my encodes seem to be playing flawlessly, but I've noticed a scene in Casino Royale which causes the iPad to studder horribly with these settings (file plays perfectly on a mac so it's not a bad encode).

Question is, do we A, feel confident that iPad 3rd gen can handle 4 ref frames, and B, that it can handle -1,-1 deblocking? If so what else would be a drag on processing power? Could raising the constant quality value to 21 or 22 improve playback?

Please excuse the lack of an activity log, I've encoded 10+ blurays since this one so I'm assuming that info's long gone.

EDIT: Just to clarify, source is Blurays brought into handbrake via MakeMKV

EDIT2: Did some more testing. I'm using the iPad with a GoFlex Satellite drive to stream HD video. Works flawlessly for most of the movies I've tested, but this particular scene won't stream smoothly. Plays perfectly when stored directly on the device. I'm assuming this is an issue of the bitrate being to high to stream over wifi? Would raising the RF value solve that? Going to try and test it but would love any suggestions you guys might have.

Hi,

I've tried reading through all these posts and the FAQ and the guides to try and answer a question I have about file sizes so I'm turning to you guys to help me solve this. I just created an mp4 of Hop & Girl with the Dragon Tattoo from mkv files. Tattoo is almost an hour longer and has much more movement and darker scenes (which is why I assume the mkv file was around 45GB) while Hop was about 25GB (mkv). I used the exact same settings (RF18, 1080p, High Profile) and somehow the Tattoo file came out around 3.91 GB and the Hop movie came out at 15GB. As I said before, the settings were exactly the same. I also compared the Tattoo mp4 to the blu-ray and it was identical, no pixelation, you couldn't tell the difference. So how in the world is it that the file size was less than 4GB even though it was by far the darker, more action packed (not to mention an hour longer) and the quality was impeccable while the Hop mp4 was 15GB? The only difference I saw was that when I right clicked on the mp4 files and selected "get info" the finder window says that the Hop movie total bit rate was 21,300 while the Dragon Tattoo info says it's total bit rate was 3,301. I guess what I don't understand is how the bitrates can be so drastically different if I had the same settings and also how the Dragon Tattoo file looks flawless considering the file size (it's even a smaller size than the iTunes version). Is there some other way to control the total bitrate? Because if so, I certainly wouldn't mind having all my movies bit rate around 3,300 so I can have impeccable, yet small in size, movie files. Can anyone explain what's going on here? Thanks! Below are the logs, by the way...

Re: *** AppleTV 3 and the New iPad (Presets) ***

Three things come to mind.
  1. Hop has a larger frame than GwtDT as it is a 1.85:1 ratio vs. 2.40:1, so you're looking at a frame size that's 30% larger.
  2. Animation contains many more hard edges, which can cause bitrate spikes on constant quality encoding.
  3. Your chosen RF is excessive for 1080p encodes - RF 23-21 is more suitable for this resolution.
Variation in file size/bitrate isn't just a side effect of constant quality encoding, it's the essence of it. You're aiming for a chosen quality metric, not some arbitrary bitrate.

Thanks. I'll try changing the RF. I have been since tried two other films - the descendants and my week with Marilyn. The same thing happened. My week with Marilyn was around 4.6GB and the descendants was 14.5GB. In this case, the frames are the same size.

Both Hop and The Descendants have fairly heavy grain. So with your low RF values, you're wasting a lot of bitrate on accurately preserving noise.

Would the heavy grain truly account for a 9-10GB difference though? Also, how can you tell how much grain a movie has? (Specifically, I mean, so i can adjust the RF). I've since continued to try movies and the ONLY difference I've noticed, so far, is that on the back of every movie case that ends up in the 12GB+ range it is marked as a dual-layer blu ray. Would that matter at all?

At an RF of 18, sure. Most people here use 22 or higher for HD encodes.

Simply looking at the movie, or screenshots of it, would be the easiest way. Film grain is fairly easy to identify.

Take a look at these two screenshots of Predator. The first one shows a scene with the grain intact, the second one shows the same scene with the grain digitally removed.

Saving Private Ryan and the first Jurassic Park are good examples of movies with heavy graining.

A dual layer BD alone isn't conclusive evidence. The space could be taken up by extras or additional audio tracks, or the movie could simply be inefficiently compressed.
