The Standard Video Compression Settings dialog box lets you configure the video compression settings when exporting a QuickTime Movie (.mov) file.
How to access the Standard Video Compression Settings dialog box
- In the top menu, select File > Export > Movie.
The Export to Movie dialog box opens.
- Click Movie Options.
The Movie Settings dialog box opens.
| Parameter | Description |
|---|---|
|
Compression Type |
Allows you to select the codec to use for the video stream of your movie file. The availability of codecs may vary between machines. If you are unsure of which codec is best fit for you, it is recommended to use H.264 for maximum portability, and to use Animation if quality is more important. NOTE The Animation codec, among a few others, allows you to set the colour depth to Millions of Colors+, which supports transparency.

Motion |

|
Frame Rate |
The amount of frames per second for the video stream. Leave this setting to Current to use your project's frame rate. |
|
Key Frames |
Some codecs compress the video by recording a limited amount of keyframes, which are frames in which the entire picture is encoded, pixel by pixel and, in-between, recording deltas, which are frames that are only defined by their difference with the previous frame. This significantly reduces the size of the movie file. However, the less keyframes a movie has, the more it is likely to encounter decoding errors, and the harder it is for players to scrub or jump to a specific time in the video. This option allows you to decide when keyframes are inserted in the video stream. Automatic: Lets the encoder decide when keyframes should be inserted. Every ... frames: Allows you to set the exact interval, in frames, at which keyframes should be inserted. All: Encodes every frame as a keyframe. This option will significantly impact file size, but will make it easier to scrub through the video without causing any rendering error. NOTE If you are using the H.264 codec, you must set the Key Frames option to All, or you will get an error message when you confirm the compression settings.

Frame Reordering |
Encodes frames in a different order than the one at which they are meant to be displayed. This allows for more efficient compression, but may not be compatible with some players. |

Depth |
Allows you to set the colour depth for your video. A lower colour depth will reduce the size of the video stream but will have significant impacts on picture quality. |
|
Quality |
Lets you choose a quality setting for the video compression. A higher quality setting will increase the size of the movie file, but will look better. A lower quality setting will reduce the size of the movie file, but will cause blurriness and compression artifacts to appear in the picture. |
|
Scan Mode / Interlaced |
Allows you to choose between the following scan modes:
NOTE Some codecs will display a drop-down allowing you to select Interlaced or Progressive, while others will simply have an Interlaced checkbox.
|
|
Aspect Ratio |
Allows you to select one of the following aspect ratios:
|
|
Filter |
When exporting with the PNG compression type, this determines the algorithm with which each pixel is encoded relative to other pixels. Leaving this option to Best will export in the most space-efficient filter, without compromising picture quality. Picking a filter may increase rendering speed a bit, at the expense of some disk space. |
|
Data Rate |
|
|
Automatic |
Lets the encoder use the optimal bit rate for your compression settings. |
|
Restrict To |
Allows you to specify the encoding bit rate. NOTE This setting will override other compression settings, so that the specified bit rate is respected.
|
|
Optimized For |
Optimize the encoding to be responsive depending on the intended viewing method:
