The MediaHub consists of two panels: the browser and the MediaHub tabs. Use the browser to locate the files to import, or the location where to export your clips. Use the MediaHub tabs to set you media and sequence import options.
Enabling Cache Source Media ensures that the application is the sole owner of the media, preventing the media from being modified by an external source. With Cache Source Media disabled, the application decodes the clip on-the-fly and there is no transcoding.
You can always change your mind after importing a clip: right-click the clip and select to transcode the media and copy it to your local storage. Right-click and select to get rid of the transcoded copy and refer back to the original media.
|Centre/Crop||The source image, centred, over the destination resolution frame. If the source is larger than the destination, it is cropped. If the source is smaller than the destination, it is surrounded by a black border.|
|Crop Edges||One edge of the source into the destination resolution frame without stretching or squashing the frame. Excess parts of the source frame after resizing are cropped. |
If the source—after the one edge is resized—is wider than the destination, its overhanging left and right edges are cropped. If the source is taller than the destination, the upper and lower edges are cropped.
|Fill||The source, width, and height, into the destination resolution frame. This process, if the source and destination resolutions do not have the same aspect ratio, can distort the image.|
|Letterbox||The source to the destination resolution frame without squashing or stretching it, and without cropping the source. |
If the source is wider than the destination, black bars fill the top and bottom of the destination frame. If the source is narrower than the destination, black bars fill the right and left sides of the frame. In all cases, the entire source frame is fit into the destination frame.
|Lanczos||Excellent and sharp results. Recommended for upscale and downscale. Expensive to compute.|
|Shannon||Excellent and sharp results. Results are sharper than Lanczos in small details. Recommended for upscale and downscale. Expensive to compute.|
|Gaussian||Medium quality and softer results.|
|Quadratic||Medium quality and softer results.|
|Bicubic||High-quality results, but not as sharp as Shannon. Use for both upscale and downscale.|
|Mitchell||High-quality results, but not as sharp as Shannon. Use for both upscale and downscale.|
|Triangle||Low quality results that are fast to compute. Use for downscale.|
|Impulse||Very low quality results that are fast to compute. Use for downscale.|
Be careful when using the Use Framerate search option with FCP XML files, especially if the FCP sequence is using multiple frame rates. With Use Framerate enabled, Smoke uses the frame rate of the sequence's edits as a match criteria to relink to the correct sources: if the frame rate of the considered source is 24fps while the edit is at 30fps, that source is not a potential candidate. Whether or not Smoke relinks the considered source to the edit has nothing to do with the frame rate of the sequence.
But, if you are importing an FCP sequence, Smoke timewarps the edits so that they match the frame rate of the imported sequence. For example, an FCP sequence @60fps contains edits @50fps: Smoke timewarps the edits to 60fps as it imports the sequence. Whether or not edits are relinked to their sources has nothing to do with this: if Use Framerate is enabled, Smoke only relinks the above edits if the sources are matching the edits' original frame rate, in this case 50fps.
