Encoder Presets and Tunes
|
||||
==========================
|
||||
|
||||
Presets
|
||||
--------------
|
||||
|
||||
Some encoders expose a preset and tune system. These can be adjusted from the Video Tab.
|
||||
|
||||
These provide a means of adjusting the encoder parameters to trade encoding speed for better quality and / or filesize.
|
||||
Changes to the preset may also require changes to the quality slider or bitrate for optimium results.
|
||||
|
||||
Specific encoder settings can be overridden via the "Extra Options" box but this is typically not required.
|
||||
|
||||
Best practice is to use a preset around the middle. in
|
||||
|
||||
Tunes
|
||||
--------------
|
||||
|
||||
The x264 and x265 tune options assign some additional options which will optimize the
|
||||
encoder for certain types of content.
|
||||
|
||||
If you are unsure or your content doesn't really fit into one of the following
|
||||
tunes, you can simply leave this option at "None".

Profiles and Levels
|
||||
==========================
|
||||
|
||||
Video Profiles
|
||||
--------------
|
||||
|
||||
Define the features / capabilities that the encoder can use.
|
||||
|
||||
You can think of the profile as the level of complexity required in encode / decode. The higher the complexity, the more CPU power is needed to encode/decode. Setting a profile, constrains the encode to using settings that are allowed for that profile level.
|
||||
|
||||
Typically, devices will advertise that they are compatible for a particular profile and level, so you can simply set the option that matches your device for the best chance of compatibility.
|
||||
|
||||
Note that setting a profile does not mean your encoded file will end up being that profile. It simply prevents options being used that would breach that profile constraint.
|
||||
|
||||
Levels
|
||||
------------
|
||||
|
||||
The levels are another form of constraints that define things like maximum bitrates, framerates and resolution etc. The following wikipedia articles lists the relevant information for each level.

||||

||||

| HEVC / H.265| https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding_tiers_and_levels |
|
||||
|
||||
|
||||
Most devices (and sometimes, software decoders) support a "maximum" level. When
|
||||
the video's specifications exceed that level's constraints, the decoder won't be
|
||||
able to decode the video properly (it may simply refuse to play the file).
|
||||
|
||||
HandBrake's encoders, set the appropriate level automatically based on all the other settings. To make sure your video doesn't exceed a specific level, you simply have to make sure the other parameters fit within the constraints imposed by the level.
|
||||
|
||||
It is recommended that you leave this setting on "Auto" unless you require to set it for device compatibility.

Intel Quick Sync Video Advanced Configuration
|
||||
Intel Quick Sync Video
|
||||
==========================
|
||||
|
||||
|
||||
Supported Hardware and Configurations
|
||||
--------------
|
||||
- Intel Sandy Bridge (2nd Generation Core) CPU's with Intel HD Graphics better
|
||||
- Windows 10 (GUI and CLI)
|
||||
- Linux (CLI Only when compiled from source with --enable-qsv. Considered experimental)
|
||||
|
||||
Please note, these are not hard limits and the feature *may* work on older cards and operating systems, but this is not officially supported.
|
||||
|
||||
Enabling support
|
||||
--------------
|
||||
Support for the QuickSync encoder can be enabled in preferences under the video tab. If your system is not supported, the option will be greyed out.
|
||||
|
||||
|
||||
Performance
|
||||
--------------
|
||||
Take note that only the decode (when enabled) and encode portions of the pipeline is done on the Intel hardware.
|
||||
Every stage in the pipeline in-between including (decoding, filters, a/v sync, muxing etc.) all happen on the CPU. As a result, it is normal to have high, or 100% CPU utilisation during encodes.
|
||||
|
||||
It is common, particularly on lower end hardware that the CPU may be a bottleneck for the encoder. To minimise this effect, turn off any filters that you do not require.
|
||||
|
||||
|
||||
Using the Advanced Options
|
||||
--------------
|
||||
QuickSync does have a limited set of advanced encoder options that can be used. Generally speaking is is not recommended to change these parameters.
|
||||
The built-in presets offer a good range of options.
|
||||
|
||||
From the command line, you can use the --encopts parameter as follows:
|
||||
|
||||
--encopts="option1=value1:option2=value2"
|
||||
--encopts="option1=value1:option2=value2"
|
||||
|
||||
|
||||
From the graphical user interface, just set the options in the dedicated text box:
|
||||
|
||||
option1=value1:option2=value2
|
||||
option1=value1:option2=value2
|
||||
|
||||

x264 Presets and Tunes
|
||||
======================
|
||||
|
||||
## x264 Presets
|
||||
|
||||
x264 exposes a preset and tune system. Presets range from:
|
||||
|
||||
- UltraFast - Very high speed encoding, but requires much higher bit-rates to
|
||||
maintain quality. This means you can expect much larger file sizes.
|
||||
- Placebo - Extremely slow encoding but provides the best Quality and/or
|
||||
filesize for a given source. - This option is often considered a placebo
|
||||
because it offers diminishing returns in terms of quality and filesize.
|
||||
|
||||
Typically, it's recommended to use the Very Fast to Slow settings range for best
|
||||
results, or one of the slower options if you don't mind the speed loss. Medium
|
||||
is a good balance and most of HandBrakes presets use this option.
|
||||
|
||||
## x264 Tunes
|
||||
|
||||
The x264 tune options assign some additional options which will optimize the
|
||||
encoder for certain types of content.
|
||||
|
||||
If you are unsure or your content doesn't really fit into one of the following
|
||||
tunes, you can simply leave this option at "None".
|
||||
|
||||
- Film
|
||||
- Real life footage, films etc may benefit. (Not Cartoons or Anime).
|
||||
Typically won't do any harm to if left on for most content.
|
||||
- Animation
|
||||
- Used for hand-drawn animated content.
|
||||
- Grain
|
||||
- Typically used for very grainy or old content.
|
||||
- Still Image
|
||||
- Can be used for Slideshows, Presentations etc where there is very little
|
||||
moving content.
|
||||
- PSNR
|
||||
- Used for benchmarking quality. Should not be used for normal use.
|
||||
- SSIM
|
||||
- Used for benchmarking quality. Should not be used for normal use.
|
||||
- Fast Decode
|
||||
- Optimise for faster decoding. Useful for low power devices that struggle
|
||||
to decode the video.

Profiles and Levels
|
||||
==========================
|
||||
|
||||
H.264 profiles
|
||||
--------------
|
||||
|
||||
Define the features / capabilities that the encoder can use.
|
||||
|
||||
HandBrake exposes 3 profiles for H.264 Encodes. You can think of the profile as
|
||||
the level of complexity required in encode / decode. The higher the complexity,
|
||||
the more CPU power is needed to encode/decode. Setting a profile, constrains the
|
||||
encode to using settings that are allowed for that profile level.
|
||||
|
||||
Typically, devices will advertise that they are compatible for a particular
|
||||
profile and level, so you can simply set the option that matches your device for
|
||||
the best chance of compatibility.
|
||||
|
||||
- Auto (Recommended)
|
||||
- This will automatically set the profile based on all the options that
|
||||
have been selected.
|
||||
- It is recommended that you use this option unless you need to set a
|
||||
profile to ensure compatibility for a particular device.
|
||||
- Baseline
|
||||
- Baseline encodes are the most basic form of encoding. While decoding is
|
||||
much easier, it may also require much higher bit-rates to maintain the
|
||||
same level of quality.
|
||||
- Main
|
||||
- The middle ground. Most modern / current devices will support this
|
||||
profile.
|
||||
- High Profile
|
||||
- For best quality and filesize at the expense of CPU time in both decode
|
||||
and encode.
|
||||
|
||||
Note that setting a profile does not mean your encoded file will end up being
|
||||
that profile. It simply prevents options being used that would breach that
|
||||
profile constraint.
|
||||
|
||||
H.264 Levels
|
||||
------------
|
||||
The levels are another form of constraints that define things like maximum
|
||||
bitrates, framerates and resolution etc. The wikipedia article lists the
|
||||
relevant information for each level.
|
||||
https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels
|
||||
|
||||
Most devices (and sometimes, software decoders) support a "maximum" level. When
|
||||
the video's specifications exceed that level's constraints, the decoder won't be
|
||||
able to decode the video properly (it may simply refuse to play the file).
|
||||
|
||||
HandBrake's H.264 encoder, x264, sets the appropriate level automatically based
|
||||
on all the other settings. To make sure your video doesn't exceed a specific
|
||||
level, you simply have to make sure the other parameters fit within the
|
||||
constraints imposed by the level.
|
||||
|
||||
It is recommended that you leave this setting on "Auto" unless you require to
|
||||
set it for device compatibility.
