Ive been using handbrake to convert MKV to H264 or MP4 so it can play in my car head unit (2013 Pioneer AVH-X8500bhs).
Sometimes the video will play ok from start to end, sometimes it freezes but can be played back again by pressing the play/pause button. Sometimes this happens only 3x for the whole video, sometimes it happens like 20x.
I am converting the revolution TV series and original MKV file size is around 1.7GB and the h264/mp4 output is around 700-800MB.
In this regard, can you give me the most basic setting (baseline) so that my head unit will not have a hard time in decoding the video.
my settings now: (Handbrake)
Display Size = 800x450
Container = Mp4
Video Codec = H264 (or Mpeg-4 Ffmpeg)
Anamorphic = Loose
Modulus 16
Äudio = AC3 / Codec = AAC (faac) Bitrate = 160
Mixdown = stereo
Profile = Baseline
Tune = Film
H264 level = 2.2
H264 preset = default
Framerate = same as source (variable)
Quality = Constant (10)
Should I click advanced settings?
My computer for encoding = i7 (3.6Ghz 3820) 32GB ram multiple Hard drive Geforce 660ti
Note: When using xvid, the video plays without any problems on my head unit (i use Xvid4PSP to encode but the thing is, audio is not as good - only mp3 320bit- and batch conversion gets errors in xvid4psp) xvid file size is 500-600MB

Display size probably needs to be standard definition, which is not any larger than 720x576. The 800 in that 800x450 is likely a problem.
Knowing what bit rate you are using would be very helpful. The number of reference frames needs to be 5 or fewer, but you'll have to put a video through MediaInfo and post the results so we can tell if that's happening or not.
Actually your MP3 audio should be BETTER than you AAC audio at those settings. -
1) Ok thanks i will set it to 720x480. I only made it 800x450 because as per the wesbite, the resolution of my head unit is 800x480 (I cannot use 720x576 because it has a limit of height = 480)
2) Where do i set the bitrate in handbrake? Actually as per the manual, it says that my headunit can handle a max of 8000kb bitrate but i think thats too high. What would be a good bitrate for my needs? I don't want the video to look ugly, i still want it to look nice.
3) How do i set the number of reference frames to 5 or lower? Is it in the advance settings ?
4) Well the sound of the AAC is a bit bigger specially on the bass side. It might not be noticeable to others but im a bit particular in music/sounds. The extension of the sound in AAC is also better. More body. -
This is the media info of the original file. I will post the media info of the converter file when i get home.

Note: episode 1 only has AC3 audio but the others have AC3 and AAC to choose from -
If the player's manual tells you the AVC Profile and level it supports, use them (assuming you're not already). High Profile, Level 4.1 is pretty standard these days. Handbrake's High Profile preset uses Level 4.1 (along with the default x264 settings), but you can change it. Hopefully once you do, the stuttering problem will go away. The number of reference frames etc should stay within the limits of the chosen Profile and Level.
PS And if the player has a maximum resolution it supports, you'll need to resize if necessary to stay within those limits. -
yeah the manual of pioneer states this:
Baseline Profile
8000kbps
max frame rate = 30fps
audio codec = AAC
Decode size - Max 1280 (W) x 710 (H) - (however, on the website, it says that the screen resolution is 800x480 so i lower my size to 711x400) I set it at 720 but it automatically makes it 711 maybe because of the anamorphic loose and modulus 16
However, it doesn't state what level I should use. Since the manual says the max bit rate is 8000 kbps, then I assumed that it is level 2.2 since lev3 is max 10,000kbps and level 2.2 is 4000kbps. Am I right on this?
In handbrake, do i set the FPS as Same as source or 30? Should i choose constant framerate or Variable? Which has better compatibility (or would not make the head unit work that hard).Last edited by joms; 5th Sep 2013 at 19:10.

The last part doesn't quite make sense. 711 isn't mod16 (it doesn't matter what you use anyway, so if you need it to be mod2, make it mod2). Do you mean Handbrake automatically makes it 720?
You're possible getting the width and height mixed up. "Max 1280 (W) x 710 (H)" seems correct. You seem to be setting the width to 720 (or 800) when it's the height which is limited to 710.
Same as source and constant frame rate.
This paragraph may be wrong as I just realised the limit is 8000kbps, not 80,000kbps as I thought it was.
You shouldn't need to worry about bitrates given you're encoding at a low resolution. I just checked my last Bluray encode (1280x542) which was encoded using CRF18.... and it's an "action movie", and the average bitrate is 3781kbps and the maximum 18150kbps. You'll never hit 80000kbps encoding at a low resolution.
Are you using CRF (quality) encoding now? I'd stick with that and specify the quality. The bitrate will vary accordingly. If you want to check the video bitrate after encoding, Bitrate Viewer will do it for you.
I'm pretty sure you are. Although..... I'd probably try level 3 wile adding some extra bitrate restrictions to the command line so you're not being limited to 4000kbps by Level 2.2. So you'd use Level 3 and put something like this in Handbrake's command line area (Extra Options, I think it's called).
--vbv-bufsize 8000 --vbv-maxrate 8000
The above will work in probably every GUI except Handbrake. Handbrake uses different formatting for command line options than the rest of the world, so my best guess for converting x264-speak to Handbrake-speak is this. I don't have time to check it right now though.
vbv-bufsize=8000:vbv-maxrate:8000
If that doesn't fix the freezing problem then reducing the number of references frames would probably be the next step.
I assume your encoded video displays correctly? Not all hardware players support anamorphic MP4/MKV, which means they display it as though it uses square pixels. If you're re-encoding video with square pixels (almost everything except DVD), I'd not use anamorphic encoding myself. Anamorphic "none" will output square pixels. I don't use Handbrake much, but I think the best bet would be to use anamorphic none and mod2. The latter will allow Handbrake to resize to square pixels as accurately as possible.Last edited by hello_hello; 5th Sep 2013 at 19:52.

Hi. Thanks for the reply

For your info:
Am I right to interpret this such that even if H264 can decode at a higher size (1280x720), I should still follow the native resolution of my screen which is 800x480 ? (is that my native resolution?)
-------------------------------------------------------------------------------------------
Is CRF also the same as RF? It so then yes i am using this and my setting is 10, sometimes i try 15.
What will level 3 offer over level 2.2? If its quality then i think im already ok with the picture quality. However, if its stability then i'm highly interested as I want my video to play as smooth as possible (with acceptable quality).
Encoding time is not important to me since I can just queue them while im sleeping. File size is also not that important as I have a couple of big thumb drives that i can use (32GB, 64GB and 128GB)Last edited by joms; 5th Sep 2013 at 21:03.

You should just work your way through some of the presets like AppleTV, Android, or Android Tablet. Or try Profile@Level Main@3.0 or Main@3.1 to the Normal or High Presets. Your device seems to have limits somewhere between the Main and High profiles:
https://en.wikipedia.org/wiki/H.264#Profiles
Approximately level 3.0:
https://en.wikipedia.org/wiki/H.264#Levels
Let Handbrake handle the details for you. Except maybe the max bitrate which needs to be a little lower than level 3.0. But with a 720x480 or smaller frame size it's highly unlikely you'll ever get bitrate peaks over 8000 kbps with a reasonable RF value (18 to 20).Last edited by jagabo; 5th Sep 2013 at 21:29.

yes, use a video resolution at or less than your display resolution
its a TV series, so try 800*450 at 6000kps per second or less, not the max rate of 8000
the original is going to be 16:9 display aspect unless its been cropped, 800*450 is 16:9
this will give you 15pixels black bar top & bottom while going full width, with NO distortion
stay within the coding specs listed for the device -
umm, so how do i set all the bit rate in handbrake? i don't see any setting where I can place 6000kbps. Also, should i only use 18 to 20 for RF value? does RF value make decoding harder for my pioneer head unit? Hmmm maybe my video skipped because i tried putting an RF value of 2, 3, 4 and 5 before? (was trying different RF values)
Also 800x450 might not be good because that is not SD already right? It might make things harder for my head unit to decode. What I do is only 720x400 but it turns out to be a box when played. I just hit the stretch feature in my pioneer and the video automatically fills the entire monitor. -
Change from Quality based encoding to Avg Bitrate based encoding -- on the Video tab. You have to choose one or the other.
You can use any RF value you want, from 0 to 51. The lower the value the higher the quality and the higher the bitrate. But many people consider RF=18 to be pretty high quality at normal playback speed (if you zoom into still shots you'll see differences). There's not much point in going with a lower RF (higher quality) than that -- especially on a small screen. Most stuff you might download from various sources is significantly lower quality -- typically in the RF=25 range. If RF=18 gives files that are too large for you, or bitrate peaks over 8000 kbps, try going to a higher RF.
Not necessarily. It depends on how high the bitrate gets. There are two basic methods of encoding: "quality" and "bitrate". With quality based encoding you specify the quality you want, the encoder uses whatever bitrate is necessary to deliver that quality. With bitrate based encoding you specify the bitrate (and hence file size since: file size = bitrate * running time) but you don't know what the quality will be.
You can use Bitrate Viewer to see a graph of bitrate over the length of your video. I suggest you try RF=18 then view the bitrate graph. -
Thanks for the reply.
So in my case, I would better use the Avg bitrate method right? Because even if I use the RF method then check it with bitrate viewer, that would only apply to that particular video. I intend to convert different type of videos (and a lot). So to be safe that the bitrate would fall below 8000kbps, I should just use avg Bitrate and place it at 6000kbps?
Note: I'm not really concerned about file size.
Should I also set the frame rate to 30 and constant? To be sure that it won't go over 30fps? I really don't want to check the fps of all the videos i want to convert. I intend to convert them by batches after setting my preset. -
i would check the frame rate of each video
i would set the conversion frame rate to match original file frame rate
there is NO need to convert a 25 fps mkv to 30fps mp4.. keep it 25fps
since you are not making dvd's converting frame rate will just add 'interpolated' frames and create quality problems -
theewizard - i understand that there is no need to convert a 25fps to 30fps but if you have hundreds of MKV videos, it will be tiring to check each and everyone. What I want to do is to drag them all to the converter and let it sleep overnight (or the whole day or two). (I have a lot of MKV in my synology NAS which I use to watch video at home. I just need to convert them so that I can watch them in my car as well)
Will the quality problems from interpolated frames be that big and noticeable to a car video screen? (800x480). If its size that you are worried about then its no problem with me. If it, however, will affect the reliability of playing the video, then that is something i want to consider.
(note that these h264 videos for my car is not a part of my collection that i intend to keep. I have a higher resolution file in my NAS (1080p) which I use for my home. I only intend to watch these converted videos several times in my car then maybe erase them afterwards) -
711 is the display aspect ratio, not the resolution. That's the result of using anamorphic encoding. The resolution and display aspect ratio are only the same if the video contains square pixels. DVDs are the most common example. 720x480 isn't 4:3 and it's not 16:9 either.
So for your example the video is actually being encoded at 720x400, but in order to display correctly without distorting the picture, it'll display using 711x400. If the playback device doesn't support anamorphic MKV/MP4, then it'll display as 720x400 instead of 711x400, so the picture will be stretched horizontally a little.
CRF 18 is roughly where the x264 encoder is supposed to be "transparent". Higher values lower the quality. CRF10/15 is fairly extreme, especially when encoding at a low resolution which will be played on a low resolution screen. If you were going to play the video on a TV while it's resized back to 1920x1080 then you'd want to use a low CRF value, but for a portable device I'd imagine the x264 default (CRF23) would be quite adequate.
It may compress the video a little more given it can use more reference frames.
A quick thought on the frame rate part of the discussion. You should use "same as source" and constant frame rate.. If HandBrake does something silly like reset it every time you open a video for encoding, try creating your own Handbrake preset (based on the Handbrake Profile you normally use) and save your preferred setup as a new Handbrake preset. -
Thanks, I marginally got what you meant by anamorphic and aspect ratio.
Question is, which one would be easier (non taxing) for my pioneer head unit. (Therefore less chances of getting freezes)
a) set the picture size to 800x480 (pioneer's resolution) and remove anamophic and uncheck the keep aspect ratio
b) set the picture size to 720(width) with anamorphic Loose and Modulus 16 (giving me a display aspect resolution of 711x400 then just using the Zoom/stretch/fill command of the pioneer)
How would I know if my Pioneer head unit supports anamorphic encoding? It does not say in the manual nor in the website.

Hmmm I checked the manual again and it shows this for USB Connected devices (my thumbdrive):
[Attachment 19930 - Click to enlarge]
[Attachment 19929 - Click to enlarge]
Do you think my video freezes because of my audio not being AAC Itunes encoded? Can Itunes Encode a video with format H264 / AAC?
Update: I checked the video with bitrate viewer and it had an average bitrate of 3842kbps and peak of 6763kbps.Last edited by joms; 6th Sep 2013 at 10:42.

I don't even know how it came to be 7. I didn't input any number for reference frame. It's not even an option in the video tab. I think I can adjust it by clicking the Advance tab but by doing so, I won't be able to select the Baseline profile and the H264 Level. (Unless I can put something in the "extra options"field to force it to have a reference frame of 4 or 1. I don't know what to put though.
-
-
But what preset did you have selected to the right of that? The preset sets a bunch of defaults which you can then modify with the settings in the controls you pictured. You can't change the number of reframes there. You either have to start with a preset that has a lower reframe limit or use the Advanced tab intead.
-
-
After selecting the Normal preset, try changing the Profile to Baseline and the h.264 level to 3.0. Encoding with that will give 1 reference frame.
-
Ok. im doing this right now. So the only difference from what i did is using level 3.0 instead of the version 2.2 I am currently using.
-
Baseline profile at level 3.0 or 2.2 should use only one reference frame. I don't know why your previous video shows 7 reference frames instead.

Thanks!
Ok, done. I will test it when i get in my car.
