Frequently Asked Questions

What is Transcoding?

Transcoding is converting a video file into a file that is more easily streamed. Unlike encoding, transcoding involves that transformation from one digital file to another digital file. Transcoding mainly deals with file size.

Do I have to encode/transcode all the VODs uploaded to Dacast?

No, you do not have to encode/transcode all the VODs uploaded to Dacast. We actually recommend only encoding/transcoding videos that are not natively supported. More on our live encoding settings here.

Which encoding settings does Dacast recommend?

Dacast recommends Video Codec H.264,  25 or 30 frame rate, constant (CBR) encoding bitrate, AAC audio codec, and the 128 kbps audio bitrate.

Does Dacast support Dynamic Adaptive Live Stream Transcoding?

Dacast does not support Dynamic Adaptive Live Stream Transcoding at this time.

Can I broadcast in HD over Dacast?

Yes, Dacast users can stream high definition feeds, exact bitrate of which is dependent on the encoder being used to live stream. To stream at HD, please select a bitrate over 1.4MB a second and a resolution that is 720p or higher.

What is the difference between VOD and OTT?

VOD means “video on demand,” and OTT means “over-the-top.” A lot of VOD services use OTT technology to bring the content to their viewers, but OTT can also apply to live streaming. They are often used side-by-side, but they are not mutually exclusive.
