In order for stations playing your video to have the best quality when broadcasting them, it's important to consider the parameters you use for rendering the video file from your editor.
For HD/MP4 files:
For HD files, resolution must be 1080P (1920x1080) or 720P (1280x720), NON-INTERLACED. 1080P is highly recommended. Generally 720P should be used for legacy footage which was shot at a lower resolution.
HD/MP4 rendering guidelines:
When uploading, When uploading, we will transcode your HD videos into SD, so that you don't have to create and upload both an HD and SD version of every video. Keep in mind that you need to keep your titles and primary action within the "Title Safe" area if you want the SD version to display correctly. Most video editing software has an option to set that outline on your rendering window for guidance.
