Media properties


Each media asset has its own properties, which are used to control its behaviour inside your project. Some of these properties can be edited.

An asset's properties can be displayed by clicking the cog next to its name in the Project Media list.

Different types of media have different settings.

Media properties should be set according to the media asset's original specifications, not according to your project specifications (which may be different).

Adjusting a media asset's properties will affect all instances of it on all timelines.

Video properties

video properties

Name - changes the display name. This does not change the filename of the original source file.
Path - displays the location of the original source file on your computer. This cannot be edited unless the file requires relinking.

Video

These properties are automatically set using information in the source file. If you want to change them you should first untick the From File option.

Frame rate - the number of frames displayed sequentially in each second of playback.
Field type - how each frame of video is stored and displayed. Some video formats store each frame as a full resolution 'progressive' frame similar to how actual film works, while others will store 'interlaced' video which consists of two 'fields' on each frame.
Aspect - the shape of the individual pixels, which in turn affects the shape of the video frame. Some formats use non-square pixels to create widescreen aspect ratios, so make sure you check your camera's specification if your video looks stretched or squashed.
Resolution - the dimensions of the video in pixels. This cannot be edited. If you want to change the size of your video you should use the scale controls once it is on the timeline.
Color - the color depth of the video. 24-bit is the standard, while 32-bit also includes an alpha channel with transparency information. If you are using pre-keyed stock footage, for example, it will have 32-bit color.
Codec - a video codec is responsible for compression and decompression. Different codecs are suitable for different purposes, with some best for retaining quality and others designed to reduce filesize.

Audio

The audio properties of a video clip cannot be altered and are displayed for reference only.

Format - the quality and number of channels.
Sample rate - sample rate of the original file. This will be converted to match your project's sample rate.
Codec - an audio codec is responsible for compression and decompression. Different codecs are suitable for different purposes, with some best for retaining quality and others designed to reduce filesize.

Additional information about the video file is displayed for reference only:

Container - the filetype of the source file.
Duration - total length of the video, in hours:minutes:seconds:frames.
File size - size of the original file on disk.

Clicking OK will confirm any changes you have made.

Resolution - the pixel dimensions of the image. These cannot be altered.
Color - the color depth of the image. 32-bit images also include an alpha channel with transparency data.
File size - size of the original file on disk.

Clicking OK will confirm any changes you have made.

Format - the quality and number of channels.
Sample rate - sample rate of the original file. This will be converted to match your editor sequence's sample rate.

File size - size of the original file on disk.

Clicking OK will close the properties window.

Plane properties

plane properties

Name - changes the display name.
Width/Height - determines the resolution of the plane. You can make it larger, smaller or the same size as your project and composite shots.
Aspect - the shape of the individual pixels, which in turn affects the shape of the plane frame. Some formats use non-square pixels to create widescreen aspect ratios, so make sure you check your camera's specification if your plane looks the wrong shape.
Color - clicking the color box will display a standard color palette for choosing the plane's color. Alternatively, you can click and drag on the color pipette icon then move the mouse over any color on your screen. The pipette icon is particularly useful if you want to match the color of another media asset.
Match sequence/composite shot - this button will automatically adjust the plane's settings to match those of your currently selected editor sequence or composite shot.

Composite shot properties

composite shot properties

Composite shots can share the same setup as your editor sequence or be completely different.

Name - changes the display name.

Templates

At the top the currently selected template is displayed and can be changed using the menu. This area can also be used to save new templates for future use.

Choosing a template

The template menu lists a range of common composite shot types.

Once you have chosen a template you can either click OK straight away or continue to customize the options.

Saving a new template

After altering some of the video properties you might want to save the setup to a new template so that you can easily use it again in future.

Clicking the Save template button to the right of the template menu will display a dialog in which you can specify a name for the new template. If a template already exists with that name you will be asked if you want to replace it.

The default templates cannot be changed or replaced.

The new template will then be available from the template menu.

Removing a template

The Remove template button will permanently remove the currently selected template from the list.

The default templates cannot be removed.

Standard

Video

These options affect how video is handled in your composite shot.

Width & height - the resolution of the video frame in pixels.
Frame rate - the number of frames displayed sequentially in each second of playback.
Aspect - the shape of the individual pixels, which in turn affects the shape of the video frame. Some formats use non-square pixels to create widescreen aspect ratios.
Match sequence/composite shot - this button will automatically adjust the composite shot's settings to match those of your currently selected editor sequence or composite shot.

Audio

Sample rate - sample rate of the original file. This will be converted to match your editor sequence's sample rate.

Clicking OK will close the properties window.

RECAP All media types have unique properties, some of which can be altered.
