Preparing your job-related for Video¶

Once you master the arts of 3D animation, you will probably want to share your job-related with others;either ~ above the net (YouTube, Vimeo, etc.) or with family and friends (DVD/Blu-ray)or also possibly for television broadcast.

To preventive you part disappointment, here are some tips particularly targeted at video clip preparation.

Safe Areas and Overscan¶

For anyone developing motion graphics or basic text overlays, overscan is an important consideration.Although its beginnings are rooted in historic analog TV systems, unfortunately also in 2017,for miscellaneous reasons it can still it is in an worry with modern digital flat display screen TVs.


Due come various limitations in analog TV equipment, the presented image can sometimesend up shifted horizontally or vary in size, which can lead come the area beyondthe intended visible photo being shown. This surprise area sometimes had junk noise,timing signal or closed-caption/subtitle data. To prevent this gift visible to the viewer,the standard approach for TV manufacturers to be to ‘overscan’ (zoom in) the shown pictureby a small amount (between 5-10% edge crop) come ensure the at no time would the hidden areas be visible.

Although contemporary digital electronics have got rid of the problem of shifting image position,unfortunately, part TV manufacturers have included overscan on your flat screen TVs.Why? because for numerous years that was given that the edge of the visible photo would hardly ever be seen,so broadcasters would sometimes overlay ‘hidden’ data come the very edge that the image(e.g. Some species of closeup of the door captions). Also, legacy analog recordings could stillcontain undesirable noise roughly the edge. To avoid customer complaints,overscan is fairly often enabled by default. For part flat display screen TVs, the is not possible to disable it.

Enabling for sure Areas¶ has configurable safe-area markings which deserve to be made clearly shows by choosing the step camera,then in the camera settings by allowing Safe Areas. Numerous presets room available.If you are creating work because that a television network or indeed any client,they may have actually their very own rules and also requirements on for sure area dimensions – therefore consult v them.

Color Reproduction¶

When exporting to many of the common video clip formats, the rendered RGB(A) images go v a switch processwhereby lock are analyzed to the YCbCr color model. Y corresponds to a gray-scale depiction of the image,Cb and Cr save on computer data for the blue and also red networks respectively.Green is encoded into the Y and also Cb, Cr channels with some clever math.

Importantly, the color components are often stored at a reduced resolution to the Y (grayscale) channel.This can cause blurring/smearing which can be a trouble with little text and some saturated color combinations –so the is fine worth doing check encodes come make sure that text remains legible. As with safe areas,a TV network or customer might have their own rules on minimum message size and also positioning,so always seek clarification when unsure.

Encoding Panel¶


Properties editor ‣ Render ‣ Encoding


Encoding panel.

Here you pick which video clip container, codec, and compression settings you desire to use.With every one of these compression choices, there is a trade-off between record size,compatibility throughout platforms, and playback quality.


When you watch the system Console,you deserve to see few of the output of the encoding process.You will watch even more output if friend execute as -d.

PresetsYou can use the presets, which choose optimum setups for you for that kind of output.ContainerVideo container or document type. Because that a list of all accessible options, seevideo formats.Autosplit OutputIf your video is large and above 2GiB, enable Autosplit Output.This will automatically split the output into multiple documents after the first record is 2Gig.CodecChooses the an approach of compression and also encoding.For a perform of all obtainable options see video clip formats.



Some containers and codecs room not compatible with each other,so if you are obtaining errors inspect that your container and also codec are compatible.Like containers and codecs are sometimes not compatible through each other, part codecsdo not work with arbitrarily dimensions. So, shot to rod with typical dimensionsor study the limitations of the codec you are trying come use.

Output QualityThese room preset Rates.Encoding SpeedPresets to readjust between a fast encode (bigger paper size) and more compression (smaller file size).Keyframe IntervalThe number of pictures per group of Pictures.Set to 0 because that “intra_only”, i beg your pardon disables inter-frame video.A higher number generally leads to a smaller paper but needs a higher-powered maker to replay it.Max B-frames

Enables the usage of B‑frames.

IntervalThe maximum variety of B‑frames between non-B-frames.


BitrateSets the average bit rate (quality),which is the counting of binary digits every frame.See also: FFmpeg -b:v.RateVideo papers can use what is dubbed variable little rate (VBR).This is provided to offer some segment of the video clip less compressing come frames that need more dataand less to frames with less data. This deserve to be regulated by the Minimum and Maximum values.BufferThe decoder bitstream buffer size.


Multiplexingis the procedure of combine separate video clip and audio streams right into a solitary file,similar to packing a video document and .mp3 audio paper in a zip-file.

RateMaximum little rate the the multiplexed stream.Packet SizeReduces data fragmentation or muxer overhead depending upon the source.


Audio CodecAudio format to use. For a perform of all accessible options, seevideo formats.BitrateFor each codec, friend can regulate the bit rate (quality) the the sound in the movie.Higher little rates space bigger documents that present worse but sound better.Use strength of 2 because that compatibility.VolumeSets the output volume that the audio.

It’s not recommended to render directly to a video clip format in the an initial instance.If a difficulty occurs when rendering, the paper might come to be unplayable and also you willhave to re-render all frames indigenous the beginning. If you very first render the end a setof static images such as the default PNG layout or the higher-quality OpenEXR(which deserve to retain HDR pixel data), girlfriend can integrate them asan photo Stripin the video clip Sequence Editor (VSE). This way, you deserve to easily:

Restart the rendering from the ar (the frame) where any problem occurred.Try the end different video encoding alternatives in seconds,rather than minutes or hours as encoding is commonly much quicker than rendering the 3d scene.


You do not do it post-process a lossy-compressed record as the compression artifacts may become visible.Lossy compression need to be reserved as a last ‘delivery format’.

If you space planning ~ above doing far-ranging post-processing and color correction,it is finest to output a frameset rendered in OpenEXR format.If you setup to do just minimal changes after rendering and would favor a solitary file,choose lossless H.264 for high quality, or continual H.264 for reduced quality.
