Recommended Settings

To enable a smooth Uploading and Encoding process that will optimize the viewing experience for your visitors in all major browsers and mobile devices, it’s important that the video files are configured correctly. We recommend that you follow the Video Exporting recommendations below.
Streamio accepts almost every kind of video format and codec. One exception is the codec ProRes 422. Transcoding will be executed but a number of cases show up problems when trying to play the file, ecspecially in mobile devices, iPhone, Androids, iPads etc. We recommend to not use the video codec Apple ProRes 422!
Though Streamio handles a video format it’s of course important that the video files are configured correctly to get as good result in the end as possible. Almost every Video Editing Software in the market today let you decide how to export your video files.
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.
