DanielCZQ: Is it possible to upload videos and audios so students can stream them directly from your service?
In my case, I have 300 students. Is it possible to send videos and audios but they can't download them, just stream them directly from your service? Is it okay to do that, or do you think that it's going to override the bandwidth limit fair use policy in tier number two?
Would it work from mobile device and from PC based device.?

Jun 10, 2026A: Hi again! It is incredibly smart of you to ask these questions before rolling this out to 300 students.
To give you the short answer: Sinosend is not designed to be a video streaming platform, and for your specific use case, we wouldn't be the right fit.
Here is the breakdown of why, along with the math regarding your bandwidth question:
1. We Lack Adaptive Bitrate Streaming
While Sinosend does allow video and audio uploads and has a basic preview player, we are a secure file transfer tool built for downloads and quick previews, not dedicated streaming. (youtube/ wistia etc)
We do not have "Adaptive Bitrate Streaming." This means if you upload a high-definition video and a student has a weak mobile connection, our system cannot automatically lower the video quality to prevent buffering—the video will simply lag or stall for them.
2. Can you block downloads?No. Because we are a file transfer solution, our core purpose is to deliver files. Any video or audio file sent through Sinosend can be downloaded by the recipient;
3. You are completely right to be concerned about the Fair Use Policy here. Let's look at the math for 300 students:If you upload a single lecture video that is 500MB in size, and 300 students watch/stream it, that creates:500MB x 300 = 1500MB
Our Tier 2 (Pro) plan includes 200GB of storage, with a fair-use monthly egress (bandwidth) cap that mirrors your storage. Sharing just one 500MB video to your class would instantly consume nearly your entire monthly bandwidth allotment.
If you share multiple videos a month, you will significantly exceed our Fair Use limits.
Moving Forward If your primary goal is hosting videos that students can stream smoothly without downloading, we highly recommend looking into dedicated video solutions like Vimeo, Loom, or YouTube (set to unlisted), which are specifically engineered for high-bandwidth streaming.
However, if you still want to explore using Sinosend for standard file distribution alongside your videos, please reach out to us at [email protected]—we'd be happy to see if we can work out a custom high-bandwidth framework for your account!
