Video
Codec: H.264
A codec is the format in which your video will be encoded. Different codecs have different features and varying quality. For best results, we recommend usingH.264 (sometimes referred to as MP4).
Frame rate: 24, 25, or 30 FPS
If you know at which frame rate you shot, it is best to encode at that same frame rate. However, if it exceeds30 FPS (frames per second), you should encode your video at half that frame rate. For example, if you shot 60 FPS, you should encode at 30 FPS. If you're uncertain what frame rateyou shot at, set it to either "Current" or 30 FPS. If there is an option for keyframes, use the same value you used for frame rate.
Data rate: 2000 kbps (SD), 5000 kbps (HD)
Thissetting controls both the visual quality of the video and its file size. In most video editors, this is measured of kilobits per second (kbps). Use 2000 kbps for standard definitionor 5000 kbps for high definition video.
Resolution: 640x480 (SD), 1280x720 (HD)
Choose 640×480 for 4:3 SD video, 640×360 for 16:9 SD video, and 1280×720 or 1920×1080 for HD. Ifyou have the option to control the pixel aspect ratio (not the display aspect ratio), make sure it's set to "1:1" or "1.00," sometimes referred to as "square pixels."
Deinterlacing:Maybe
If you are shooting on an older camera, enable the deinterlacing option. Otherwise, you may get weird-looking horizontal lines in your video. With newer camera models,deinterlacing shouldn't be an issue, so you can leave this option unchecked.
Audio
Codec: AAC (Advanced Audio Codec)
For best results, we recommend using AAC for the audio codec.Data rate: 320 kbps
320 kbps is the highest quality audio data rate we currently support.
Sample rate: 44.1 kHz
44.1 kHz is the highest audio sample rate we currently support.
