Recommended Settings

Updated: 01 Dec 2011
To enable a smooth Uploading and Encoding process that will optimize the viewing experience for your visitors in all major browsers and mobile devices, we strongly recommend that you follow the Video Exporting recommendations below.

Streamio accepts all kind of video formats and codecs. No limits are known at this time.

They apply to virtually every Video Editing Software in the market today:


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 using H.264 (sometimes called 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 exceeds 30 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 rate you 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.


Video Bitrate:  2 000 kbps (SD) or 5 000 kbps (HD)

This setting controls both the visual quality of the video and the file size. In most Video Editing programs, this is specified in terms of kilobits per second (kbps).

Use 2 000 kbps for videos ins standard quality (SD) or 5 000 kbps for High-Definition video (HD).


Resolution:  640px width (SD) or 1 280px width (HD)

Use 640px width for videos in standard quality (SD) and 1280px width for High-Definition video (HD).

If you 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".


AUDIO

Codec:  AAC

For best results, we recommend using AAC for the audio codec.


Audio Bitrate:  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.
