Encoding and exporting

Last updated 12/15/2014

Video exports settings

Adobe Media Encoder is used both as a standalone application and as a component of Adobe Premiere Pro, After

Effects, and Flash Professional. In some contexts—including rendering and exporting from Premiere Pro—you set

encoding options in the full Adobe Media Encoder Export Settings dialog box. In other contexts—including rendering

and exporting from After Effects—you set encoding options in a format-specific Options dialog box that only presents

a subset of the encoding options.

Adobe Media Encoder ships with many presets, each of which sets the various options to meet the requirements for a

common target output. In the Export Settings or format-specific Options dialog box, the options available on the Video

tab depend on the format you’ve specified.

Options not documented here are either specific to the selected format or do not require documentation. For detailed

information, consult the specifications for the selected format. For example, MPEG formats include many advanced

options not listed here. For detailed information on options not listed, consult the specifications for the MPEG-2

(ISO/IEC 13818) format and the

Wikipedia website.

Note: Some capture cards and plug-in software provide their own dialog boxes with specific options. If the options you see

are different from the options described here, see the documentation for your capture card or plug-in.

For general information about compression settings, see Compression tips.

TV Standard Conforms the output to the NTSC standard or to the PAL standard. When set to Match Source, Adobe

Media Encoder automatically sets this value to match the source. For example, if the source file frame rate is 25 fps,

Adobe Media Encoder sets the TV standard to PAL.

Frame Dimensions Dimensions, in pixels, of the output frame. When set to Match Source, Adobe Media Encoder

automatically sets this value to match the frame dimensions of the source. (See

Image aspect ratio and frame size.)

Frame Rate Frame rate of the output file in frames per second. Some codecs support a specific set of frame rates. When

set to Match Source, Adobe Media Encoder automatically sets this value to match the frame rate of the source. (See

Frame rate.)

Field Order or Field Type Specifies whether the output file has progressive frames or frames made up of interlaced

fields, and if the latter, which field will be written first. Progressive is the correct setting for computer display and

motion picture film. Choose Upper First or Lower First when exporting video for an interlaced medium, such as NTSC,

or PAL. When set to Match Source, Adobe Media Encoder automatically sets this value to match the field order of the

source. (See

Interlaced versus noninterlaced video.)

Aspect or Pixel Aspect Ratio Select the pixel aspect ratio appropriate for the output type. When the pixel aspect ratio

(displayed in parentheses) is 1.0, the output will have square pixels; all others will have non-square pixels. Because

computers generally display pixels as squares, content using non-square pixel aspect ratios appear stretched when

viewed on a computer but appear with the correct proportions when viewed on a video monitor. When set to Match

Source, in H.264 and MPEG-2 formats, Adobe Media Encoder automatically sets this value to match the pixel aspect

ratio of the source. (See

Pixel aspect ratio.)

Profile Specifies whether Adobe Media Encoder will use the Baseline, Main, or High profile.

Note: Profile and Level settings are relevant to formats that use variants of MPEG encoding, including H.264.

Recommended settings are often a combination of Profile and Level settings. For example, a common recommendation for

high-quality encoding for Internet distribution is a setting of High Profile, Level 5.1. For more information, see the

Wikipedia website.

Level Level used by Adobe Media Encoder, with ranges that differ depending on output format. The different level

choices can constrain the Frame Size, Frame Rate, Field Order, Aspect, and Bitrate settings.
