the clean aperture. Fit Within Size adjusts to the destination size by fitting to the longest side, scaling if necessary.
Frame Rate Specifies the frame rate for the playback of your exported video. Usually, your video looks better if you choose a number that
is exactly divisible by the frames per second (fps) of your source. For example, if your source is captured at 30 fps, choose a frame rate of
10 or 15. Don't choose a rate greater than that of your source material.
Key Frame Specifies that key frames are generated automatically or specifies how frequently key frames are created in the exported video.
A higher key frame rate (lower number) improves video quality, but increases the file size.
4. (MP4 file format only) Click the Video Options button and specify the following:
Re-sync Markers (MPEG-4 Basic and MPEG-4 Improved only) Uses re-sync markers in the video bit-stream. This can help regain
synchronization due to transmission errors.

profiles.
Encoding Mode (H.264 only) Specifies whether you want the best quality or faster encoding.

Compression Type Choose the codec to apply when exporting a file.
Motion Specify the frame rate for your video by choosing the number of frames per second (fps). Some codecs support a specific set of frame
rates. Increasing the frame rate may produce smoother motion (depending on the original frame rates of the source clips) but uses more disk
space. If available, specify how often the key frames are generated. (See
