At NAB 2019, Datavideo announced the NVS-33, an H.264 standalone streaming encoder and recorder. The NVS-33 has HD-SDI and HDMI inputs for video as well as stereo RCA unbalanced audio connections, for use when embedded audio is not available or desired. The NVS-33 can stream and record at different bit rates simultaneously, although I am disappointed to see how low the maximum is, as I’ll explain ahead, together with four questions I asked Datavideo. The NVS-33 records onto an SD card in NTFS, FAT, or exFAT. The latter is my favorite.

Datavideo states that the front panel operation with

buttons makes this encoder desirable for many applications such as houses of worship, education, corporations and live event production. In addition to a bit rate selection button on the front panel, the NVS-33 has video input selection, stream, record, and stream + record buttons. Once the NVS-33 is setup initially using a computer or a tablet with a web browser, users can simply press one button to start their streaming and recording.

Four questions I asked Datavideo

I asked the following four questions of Datavideo, and am awaiting a reply.

  1. Is it correct that the maximum streaming bit rate of the NVS-33 is only 10 megabits per second, not 20 megabits per second?
  2. Is it correct that although the NVS-33 accepts 1080/24.000p and 1080/23.976p (aka 1080/23.98p), it cannot record or stream at either of those framerates (forced to convert the framerate and and stream/record them at 25p, creating extra frames), or is that in omission in the spec sheet I found online?
  3. When recording on a card that is formatted as exFATT, will single files over 4GB be allowed, or does it record sequential files under 4GB?
  4. Does Datavideo currently offer any H.265 encoder/recorder?

Once I receive a reply from Datavideo, I’ll either update this article or publish another one, so be sure to get on (or get back on) my mailing list after the GDPR change.

Availability and price

The NVS-33 has an MSRP price of US$699 and will be available June 2019 according to Datavideo. More information can be found here.
