The encode came out a bit choppy on the ATV especially when lots of information was on the screen - like the fight scene at about 18 minutes. Is the choppy image because of the vbv settings? RF was set at 19 BTW.
For HD sources I use an rf of 22 with those settings. Even with that vbv cap the atv can stutter at an rf of 19 ( I have seen stuttering even at 20 with those opts and vbv from an hd source). Those vbv settings were developed for the Built In preset which uses cavlc instead of cabac which is much easier to decode.

As was said an RF of 19 is too high for a blue ray source using those settings.

I've converted the same movie The Man from Earth 1280x720 MKV 4.3GB, twice using the Apple TV and DynaFlash's preset.

Apple TV.m4v = 1.58GB
DynaFlash.m4v = 968MB

That's a hell of a difference in size. The Apple TV preset looked like it produced a better video to me. Maybe only marginally but I don't care about storage.

I tried Sherlock again with the same custom settings and an RF of 21 and still got a choppy image - especially when the camera pans. At this point the image looks comparable to the ATV settings at 540p, so I think I will stick to that until Apple comes out with a new ATV. I think we've reached the end of the capabilities of the older hardware.
A little disappointing - there's always that next hurdle.

I new I shouldn't have bought that Blu-ray player. Sometimes ignorance IS bliss.

What if you use the AppleTV preset (from the latest snapshot) and simply bump the horizontal resolution to 1280? While I don't have this specific source, I have had zero problems with my Bluray/HDDVD encodes streaming to either of my AppleTVs using these settings.

While 21 is only one away from 22, the difference can be huge. I never told you to use 21. I use between 23 and 22.

Ya, tried this last night. I haven't really given up yet. It did not work. The image did not stutter as much, but there were some scenes that were unbearable. The resulting file was 3284 kbps (2.96GB), but I ran the file through VLC with the media information window up - and the problematic scenes were jumping from just above 5000 kb/s all the way up to 12000 kb/s. I think I would still need the custom vbv - can I just throw that in there?

Edit: I'm sorry, I am not using the latest snapshot - I am on 0.9.4. Would the latest snapshot be better?
While 21 is only one away from 22, the difference can be huge. I never told you to use 21. I use between 23 and 22.
I understand. I was unhappy with the loss in detail with 21, so I don't want to bother with 22. There is a scene at 12min 50sec that I use as a reference. Its Jude Law's jacket - It's basically just a dark jacket with some sort of horizontal military style pattern - I noticed that with the 540p encode the jacket looked almost all black with no detail, when its more of a dark navy blue with definite horizontal pattern/material. This is probably more of an issue with ATV scaler missing the detail and grayscale when upconverting to 1080p, but the issue is there in a lesser form even when run through VLC. RF 21 was coming close to this - although still much better - I would prefer the detail in the bad encodes.

I realize it's a bit off the subject of this post, but can I just insert a vbv-bufsize=5000 and vbv-maxrate=5000 to the ATV preset and check it out, or is there another setting that must be changed with it?

The preset from the latest development snapshot should already have vbv-bufsize and vbv-maxrate defined (vbv-bufsize=9500:vbv-maxrate=9500). Using a value like 5000 would really hurt video quality on Bluray encode (IMO).

I'm going to try the new snapshot tonight. Is RF 20 too high?

All of my Bluray/HDDVD encodes are done using the stock AppleTV preset modified to use 1280-width resolution. I've had zero issues streaming these movies from my NAS through my iMac to either of my two AppleTVs (except for maybe the first few seconds while the AppleTV works to fill its buffer).

EDIT: Just remembered, I also use slightly higher vbv-bufsize and vbv-maxrate values (9750). This was leftover from when Dynaflash, myself, and a few others were performing vbv testing in the #handbrake channel and I never bothered to update my preset to use the chosen 9500. While I have not had any problems using 9750, I would recommend using the default 9500.

I re-encoded with the snapshot at the defaults and 1280. The picture came out very good with no stutter.
Thanks for the help.

He turned himself into an mpeg4? That's a little bit far for a spare-time project. I wonder how his kids are dealing with it? Plus, for the knowledge Dyna contains, that's a pretty bloated file size. Just sayin'.

Been having some problems with stuttering all of a sudden. Unfortunately I have just too many new variables to track this down and hoping someone can point me in the right direction. I used to use windows for all my blu ray stuff, but I've been using all mac here lately so a lot of my pipeline is still being figured out. imac 27" i5 quad core, using MakeMKV to encode to a .mkv file, stripping out all the other junk from the file (subtitles, other audio tracks, other chapters, etc). From there running through handbrake snapshot svn3154 x86_64 (2010030701) using default appleTV preset changed to 23.97, CRF of 22, detelecine and decomb on, changing height to 1280x720, anamorphic turned to off, using Dynaflash's advanced string: cabac=0:vbv-bufsize=9500:vbv=maxrate=9500:ref=3:mixed-refs=1:bframes=3:me=hex:subq=7:b-adapt=2:weightb=0:trellis=0:weightp=0. When needing to convert from DTS - I've been using Moyea MKVConvertor. Then from there I metaX the file, then add in the .ac3 file/subtitle/create chapter preview jpegs with Subler.

Within the last few weeks I've bought a new iMac, changed to doing this all with OS X and just not sure what is going on. I'm re-encoding a movie from 22 to 22.5 to see if that helps. I"m going to try it next with just the AAC file incase the .ac3 file being generated by moyea is doing something weird? never heard of audio causing stutter though. Any help would be appreciated!!

Here is an encode I did of Two Towers that is stuttering really bad:

Re: AppleTV Custom Presets - 0.9.4

Post by Tom » Sun May 09, 2010 3:33 pm

Hello everyone.

I should like to preface this post by saying that I have read all of the postings in this thread and the other mentioned at the start.

I am looking to achieve the "best" quality version of my SD DVD library to watch through the Apple TV, preserving the 5.1 sound track. I don't care about file size or encoding speed.

Distilling the posts that I have read I have come up with the following custom settings. However, I am concerned that I might have picked up (more than?) one or two settings that are relevant to HD content, not SD content. Am I somewhere near the mark?

Code: Select all

cabac=0:me=umh:b-adapt=2:weightb=0:weightp=0:subq=9:vbv-bufsize=9500:vbv=maxrate=9500:no-dct-decimate=1:no-fast-pskip=1

Doesn't seem great as an advanced string given your statement you don't care about file size or encoding.

cabac=1 or it just shouldn't be on this thread.

Select Strict Anamorphic in the picture settings.

Have a look at dynaflash's linked page to make sure you have all his options then go back through the thread and pick up the Trellis and Psy-RDO (and maybe others) options from VidJock's (apologies if that is spelt wrongly) posts.

Works for me with RF 19 but means bloaty files and my poor new i7 down to only 40 fps. Syncs and plays fine on my iPhone 3GS though so should work on ATV.

Thanks for your reply. cabac=1 is now on as is Strict Anamorphic and I have moved from RF 19.25 to RF19.

Going back though this thread and dynaflash's linked page I took the majority of the settings from a post by Cavalicious » Sat Nov 15, 2008 10:51 pm and a post by Abulia » Wed Nov 26, 2008 5:02 pm.

So my ultimate quality for SD custom settings are now:

Code: Select all

ref=5:bframes=6:subq=9:weightb=0:me=umh:analyse=all:psy-rd=1.0,1.0:no-dct-decimate=1:b-adapt=2:direct=auto:vbv-maxrate=9500:vbv-bufsize=9500:trellis=1:no-fast-pskip=1:merange=24
Have I missed anything?

I will run a trial encode tonight to see what happens.

This may seem strange, but analysis hardly increases quality in my testing (both SSIM and double-blind), yet it significantly hurts encoding speeds (+- 30%). Even though no-dct-decimate increases file size, it also increases quality and it has hardly any impact on encoding speeds. I do like it that you use hex as motion estimation, since umh seems to mostly hurt encoding speeds while offering very few in terms of quality.

As a side note to everyone, I found that

Code: Select all

vbv-maxrate=12000:vbv-bufsize=2500
seems to be what the AppleTV needs to play back HD content without a hitch and I now have all Planet Earth episodes streaming perfectly to my Apple TV at 720p/24fps. Yes, even the thousands of birds in the first episode are all visible and moving! Since maxrate is still rather high, I have hardly any blockiness. Results may vary, so best to try it out yourself and share your experience.
Just to let everybody know how I have been getting on, for HD, I have used dynaflash's settings and added kvaruni's:

ref=3:mixed-refs=1:bframes=3:me=hex:subq=7:b-adapt=2:weightb=0:trellis=0:weightp=0:vbv-maxrate=12000:vbv-bufsize=2500

My HD content is now almost perfect (99%).

I used dynaflash's settings for my DVDs and have not altered it, they are good as well.

So, thank you for such a good program and for those of you that helped provide the information to make it possible!
In discussion with some of the x264 developers that are in #handbrake on IRC, we've learned that having a small value for vbv-bufsize is not a good idea. Through testing done between myself, dynaflash, and others we've determined that 720p24 streams smoothly at vbv-maxrate=10000:vbv-bufsize=10000, 720p25 at vbv-maxrate=9700:vbv-bufsize=9700. To be safe, it's probably best to use vbv-maxrate=9500:vbv-bufsize=9500 to cover all content. These settings were testing using a very difficult scene from one of the Planet Earth episodes.

First post here.

I've tried dynaflash's settings and quite a few variations on an 1080 mkv -> 720p and STILL get stuttering on my ATV (e.g. the infamous "billion birds" scene in Planet Earth). I'm ready to break and drop the vbv-bufsize down to 2500 but was wondering why, as nightstrm said, "a small value...is not a good idea"?

The Planet Earth scene works fine with the current stock AppleTV preset - with a vbv of 9500,9500. Using different settings (e.g. CABAC) can break this though.

Okay, so finally getting around to playing with some vbv to work with my advanced settings. So far I have found that since we are using cabac, very complex 720p scenes require a lower vbv limit than the built in hb presets vbv-maxrate=9500:vbv-bufsize=9500. Now this only makes sense as cabac is much harder to decode than cavlc. Therefore it only should follow that the atv cannot decode as high of bitrate from cabac as cavlc. Okay so that sucks, *however* using cabac etc. the encodes from the same source come in at a lower overall bitrate using higher profile custom settings, so the ceiling can be lower. Basically the entire bar shifts lower, which after all is one benefit of using custom settings. Lower bitrate/files size at the same visual quality.

Having said that I started working downward on a clip from a 1080p blu ray source scaling down to 720p to work on the atv at rf 22. The scene is from Avatar and has a ton of motion and complexity, its when the avatars first go out on the chopper into the forest. its about two minutes before the helicopter lands which includes the chopper flying over a waterfall (moving water is notorious for creating bitrate spikes) and the chopper lands and all of the vegetation is blowing around. Very "stuttery" without vbv at rf 22 using my preferred settings of

Code: Select all

ref=3:mixed-refs=1:bframes=3:me=hex:subq=7:b-adapt=2:8x8dct=1:weightb=0:trellis=0:weightp=0
Now starting with the stock atv preset vbv for handbrake of

Code: Select all

vbv-maxrate=9500:vbv-bufsize=9500
I noticed that the bitrate from this clip was the same as with no vbv, and as can be expected it stutter just the same. Given those two facts it is reasonable to assume that I was not hitting the vbv cap since hitting the vbv cap of course would drop bitrate from no vbv as the vbv will deny bitrate if it hits the limit on those scenes.

So in the interest of getting in the ballpark I started retesting dropping in 1000 kbps increments for both maxrate and bufsize. Each time checking output file bitrate then of course doing a visual test on the atv to try to find out when the vbv capped bitrate and as well when it capped it enough to stop the stuttering.

Finally when it got to:

Code: Select all

vbv-maxrate=5000:vbv-bufsize=5000
The stuttering went away. Played smooth like butter. Now these are quite broad strokes actually as vbv can be tuned between maxrate and bufsize to zero in closer to the ragged edge. I have not gone into further fine tuning yet, but right now on hd material I use

Code: Select all

ref=3:mixed-refs=1:bframes=3:me=hex:subq=7:b-adapt=2:8x8dct=1:weightb=0:trellis=0:weightp=0:vbv-maxrate=5000:vbv-bufsize=5000
Running the same opts without vbv on a few of my tough sources tends to yield very little overall bitrate change over the entire course of the feature, but does smooth out those "rough spots". Further testing is on my to do list but for now this is what I am using. As always YMMV. Take it for what its worth. :)

First let me say how thankful I am to have found this forum/thread and guys like dynaflash that spend so much time helping out other people. i only wish I had found this earlier before I wasted countless hours encoding movies that look horrible on my Apple TV hooked up to a 52 inch 1080p LCD.

So I am trying this again with Dynaflash's custom string he posted on 5/28. If I have this right it's just the Apple TV presets with the custom string---is that right? With previous HD conversions of something like Toy Story 2 (m2ts file) I get stuttering, large square pixeling (I forget the term for this---is it artifacting?) and changes in shading (light then dark or vice versa).

I will report back the results. Thanks again to all the folks in here who are helping.

Thank you for sharing dynaflash. Using your settings, Avatar looks much smoother now.

Okay, Great! But as I said in the initial post its broad strokes. Am hoping to refine further.

vbv-maxsize and vbv-bufsize can be hard to really pinpoint unless the device mfg. specifies the video buffer verifier ... they almost never do. The AppleTV is a total black box. Hence the need for much testing. Though I believe at this point that if anything I am on the conservative side. But time will tell. That Avatar scene is a tough one.

Someone really should run these in a streaming environment. Note that all of my tests are done on my eSata modded atv in a syncing environment. I have no reason to think they would not work with streaming but in the interest of complete testing results it would be prudent.

An Aside: People always ask why we do not provide presets for x, y and z. It's because a developer, tester or fervent user has not continued to test, retest and offer empirical evidence as its discovered as new options and advancements are introduced. It so happens that I am a very involved AppleTV user. So as new features come along, etc. I tend to test them against the atv as best I can. Sharing this is easy. Testing is time consuming in some cases, but its a selfish means to an end. I use my atv so regularly there are no set top box besides cable attached to my two flat panel tv's. *If* more users of other devices spent as much time dedicating time to their playback device of choice it would only benefit that community. But again just an aside.

I use two Mini Mac's to stream files through the network to my AppleTV's (one has content that I do not want other rooms in the house to get to)
I used the following settings to encode an HD file and then stream it through my network to the AppleTV in the bedroom. This file played beautifully, no stutters, no skips, and no pauses. I then used my second ATV to stream a completely different file at the same time. The video never even stuttered like it would do on the appletv preset.

Ok--Now I am stumped. Suddenly everything that I am encoding using the Dynaflash HD setting from 5/28 is coming up with the error message "was not copied to the ATV because it cannot be played on this ATV". I am using the custom string and the standard ATV settings with RF set to 22.5. I am getting this error on HD MKV files that are encoding including Toy Story 2, Avatar and District 9, among others. Basically everything that I've tried recently fails. Any ideas? Thanks in advance.
