That was a vendor-authored experiment—not an independent, current ranking—and BoxCast cautioned that its objective scores apply only within that test. The practical choice also depends on platform: BoxCaster requires a BoxCast subscription to activate, while BoxCast documents RTMP setup routes for VidiU and ChurchStreamer/DMB-8800A. Current availability and support for the legacy third-party units are not established by the sources cited here.
At a glance: which encoder suits which workflow?
| Encoder | Platform and setup | What the available evidence supports | Main qualification |
|---|---|---|---|
| BoxCaster (original) | Works exclusively with the BoxCast platform and requires a BoxCast streaming subscription for activation. It accepts HDMI or composite video and can use embedded or RCA stereo audio. | BoxCast’s 2018 test reported the strongest results of these three on its PSNR, SSIM, and VMAF measures, and its simulated packet-loss test showed bitrate reduction without a stream discontinuity. | Not a standalone, open-platform RTMP encoder. Output resolution depends on input format, and switching video standards mid-stream can cause failure. |
| Teradek VidiU | A hardware encoder configured for RTMP/TCP in BoxCast’s 2018 workflow. BoxCast maintains a VidiU setup article in its support collection. | The comparison tested it at 720p, 3,300 kbps, high profile, and reported a disconnect at 9% simulated packet loss. | Those observations concern the unit and software tested then, not every VidiU revision. Current support for a specific revision is unverified. |
| Digicast DMB-8800A Premium / ChurchStreamer | BoxCast documents an RTMP setup route for the ChurchStreamer, previously offered as the DMB-8800A Premium by ChurchStreaming.tv. | The documented setup includes example output bitrates and frame-rate guidance keyed to source standards. | Model revision and present-day availability and support are unresolved. The setup article warns that power cycling can erase configuration. |
Use this comparison to narrow the workflow, not to assume that older hardware is still sold, supported, or compatible with a particular ingest service. Check the exact model and revision, destination requirements, connectors, formats, and support options before deployment.
How strong is the performance comparison?
What BoxCast tested
BoxCast published its comparison on October 25, 2018. It split a 720p HDMI source—the Creative Commons video “Big Buck Bunny”—among the three devices, streamed each to BoxCast, downloaded the resulting recordings, and compared a 2:29 segment with the reference. The source was 24 fps and was converted to 30 fps for the comparison. BoxCast said frame alignment was difficult and that compared frame counts varied by less than 0.3%.
The encoder settings were close but not identical: VidiU and DMB-8800A Premium were set to 720p at 3,300 kbps and high profile; BoxCaster was limited to 3.0 Mbps, described as the closest manual setting, although the article says the model could encode up to 4.8 Mbps. BoxCast explicitly cautioned that the objective scores should be read as relative indicators for this experiment, not as absolute ratings or values comparable with unrelated tests.

Reported video-quality metrics
| Metric (as reported by BoxCast) | BoxCaster | Teradek VidiU | Digicast DMB-8800A |
|---|---|---|---|
| PSNR average | 25.085 | 18.613 | 14.853 |
| SSIM all, dB | 9.423 | 6.217 | 5.302 |
| VMAF | 30.306 | 10.092 | 25.388 |
All figures are from BoxCast’s 2018 experiment. BoxCaster ranked ahead in each metric in that setup, but these measurements are not independently replicated ratings or evidence about newer hardware, different footage, firmware, or network paths.
What the simulated network tests show—and do not show
BoxCast shared a network connection from a MacBook Pro and used Apple’s Network Link Conditioner to simulate constrained conditions. In a reduced-uplink test, it reported about four seconds of discontinuity for DMB-8800A and roughly four seconds of visual artifacting—but no audio discontinuity—for BoxCaster.
In a packet-loss scenario with a 3.5 Mbps uplink, BoxCast reported that VidiU disconnected at 9% packet loss, DMB-8800A disconnected at 5% with about four seconds of discontinuity, and BoxCaster reached the tested 10% condition with reduced encoded bitrate and no noticed artifacts, lost data, or discontinuity. These are observations from BoxCast’s specific setup and protocol path, not guarantees of how the devices will behave on a real venue network.

Platform dependency and input/output constraints
BoxCaster: a BoxCast-platform encoder
BoxCast’s product sheet describes the original BoxCaster as an HD encoder with HDMI and composite video inputs, H.264 high-profile level 4.2 encoding, embedded or RCA stereo audio, and wired or wireless networking. It is designed to work exclusively with BoxCast and requires a BoxCast streaming subscription to activate. BoxCast also describes platform-side scheduling, distribution, and archiving features; the unit should not be treated as an open-platform RTMP encoder.
Recommended Free Tools
Input format matters if 1080 output is required. BoxCast’s support page lists supported HDMI formats through 1080p at specified rates and support for analog NTSC/PAL over composite. It says 1080p30 outputs natively at 1080; other 1080 sources generally output at 720 unless a qualifying 1080i60 signal is manually set to 1080. Confirm the precise camera or switcher format rather than assuming every 1080 input produces 1080 output.
BoxCast’s support article, “BoxCaster-Compatible Video Resolutions + Frame Rates,” dated October 30, 2023, warns: “The BoxCaster has to encode for a specific standard so switching between standards mid-stream (e.g. changing resolutions or switching from HDMI to RCA) will cause video failure.” Keep the video standard consistent for the duration of a stream.

VidiU and DMB-8800A: verify revision and ingest needs
BoxCast’s 2018 VidiU test used RTMP/TCP and described strict constant-bitrate behavior for the tested unit and software. BoxCast’s support collection lists a VidiU setup article, but that listing does not establish support for every revision or confirm compatibility with every platform’s current ingest requirements.
BoxCast’s DMB-8800A Premium article says the model was previously offered by ChurchStreaming.tv as ChurchStreamer and documents a ChurchStreamer-to-BoxCast RTMP setup path. Its example directions specify 1080p at 4,800 kbps, 720p at 2,800 kbps, or lower resolutions at 1,000 kbps, with frame-rate settings keyed to source standards. These are setup examples in BoxCast’s article, not universal recommended settings for all destinations. The article also says the device ships with a static address by default and warns that power cycling can erase its configuration.
Choosing between the three
Choose BoxCaster when the BoxCast workflow is the priority
- You intend to use BoxCast and accept its required subscription for activation.
- Your source connectors and exact format match the supported inputs and output behavior you need.
- You value the results in BoxCast’s historical comparison, while understanding their test-specific limits.
Consider VidiU or DMB-8800A when you need a documented third-party RTMP path
- You already own a specific unit and its revision meets the destination’s current ingest requirements.
- You have confirmed the necessary input, resolution, frame rate, bitrate, network configuration, and setup instructions for that exact device.
- You can verify current availability of documentation, firmware, and technical support before relying on the unit for an important event.
BoxCast’s documentation establishes setup routes for VidiU and ChurchStreamer/DMB-8800A, but does not promise compatibility with every platform or firmware. It also does not establish current stock, warranty coverage, repair options, manufacturer support, or total ownership cost for these legacy devices. Compare the actual subscription or platform costs and the cost of obtaining and supporting the exact hardware revision; current prices are not established here.

Checklist before buying or deploying
- Identify the exact hardware revision. Do not assume that setup instructions or test results for one VidiU or DMB-8800A revision apply to another.
- Confirm the destination and ingest method. Verify that the streaming platform accepts the encoder’s available protocol and configuration. BoxCast documents specific third-party RTMP setup paths; that is not a blanket compatibility guarantee.
- Match the source to the encoder. Check HDMI versus composite, audio connection, resolution, frame rate, and video standard. For BoxCaster, verify how the exact 1080 source format will be output.
- Check network capacity and resilience. Plan for adequate uplink and test at the venue; the 2018 simulated packet-loss results cannot predict a particular real network.
- Confirm operational support and total cost. Verify current device availability, firmware, support, warranty, and any required platform subscription before committing to an event-critical setup.
Common problems and practical fixes
BoxCaster video fails after changing source or format
A mid-stream change in video standard, such as changing resolution or switching from HDMI to RCA, can cause video failure. Keep the source standard stable during the broadcast; if it must change, stop and reconfigure before restarting, following BoxCast’s current support instructions.
BoxCaster does not output the expected 1080 resolution
The output depends on the input format: BoxCast says 1080p30 outputs natively at 1080, while other 1080 sources generally output at 720 unless a qualifying 1080i60 signal is manually set to 1080. Check the exact source format and the support page’s compatibility details before changing equipment settings.
DMB-8800A settings disappear after power cycling
BoxCast’s setup article warns that power cycling can erase the device’s configuration. Record the working settings and network details, then check the exact revision’s setup guidance before a restart or relocation.

VidiU or DMB-8800A disconnects under packet loss
BoxCast observed disconnects in its 2018 simulated test, but field behavior depends on the unit, software, protocol path, and network. Check uplink quality and packet loss at the venue, verify the platform’s ingest settings, and rehearse on the actual connection instead of relying on the historical test threshold.
For a YouTube channel that needs to stay live continuously
These three devices are hardware encoders considered here for event streaming. If the separate goal is to keep a YouTube channel live 24/7 from uploaded videos, StreamNeo is a cloud alternative rather than a camera encoder: upload a recording or build a playlist, add your YouTube stream key once, and go live. It loops the uploaded video from the cloud, so a computer, OBS, and a home connection do not have to stay on. Each slot streams the upload as made, up to 4K 60fps, at one flat price per slot, and automatically recovers if YouTube drops the stream. The first day is free with no card. Monthly billing is $9.99 per month. See StreamNeo or start the free day.
