I am wondering how much bandwith is required to stream a 1080p movie from for example Youtube. I am aware that there may be things such as compression that come in play here, but can anyone provide a good answer for this anyways?

Compressing using x264, a 'typical' file ends up somewhere around 8GB for 100 minutes of movie. To stream this without problems, you need a speed of 8GB/100 minutes ~= 1.3MB/s ~= 10Mb/s.
So if you download a song and its got a virus or malware ive heard that the song will be bigger format. Is this true? If its not, then how can you tell? 0 Likes Re: Size of average song in MB. How many hundreds of megabytes long is a full-length movie that you download from Apple iTunes store? I am pretty curious how big these files are. Even with a sub ten dollar price, free disk space on one's hard drive would seem to put a crimp on how many movies one could buy.
We all have a reason to celebrate this year. Netflix has recently added the option to download its shows and movies for offline viewing. It’s like the streaming service decided to fulfill the. Download time calculator helps you to calculate the download time it takes to download a file based on your internet download speed/bandwidth. Calculate download time. Download Time Calculator. A SD movie: 750 MB; A HD Movie: 4 GB. Difference between MBps and Mbps.
It is directly dependent on compression rate (and more correctly: bitrate), though. Youtube compresses material quite strongly. Try downloading a 1080p Youtube video with some of the (many) available services and divide by length to get an average bitrate (or check the bitrate directly with some tool - your connection simply needs to be able to handle the audio+video bitrate).

I was able to calculate the bandwidth and storage for a 1080P video (with additional parameters) on this website:
- H.264 compressed 1080P HD @ 30 FPS
- 'High Video Quality' (not sure what that means)
- Average Frame Size: 50KB
- Bandwidth Required Per Camera: 12.0 Mbps
- Estimated Storage (24 hours per day * 31 days): 4 TB

http://www.quora.com/What-is-the-bandwidth-requirement-to-stream-a-1080p-HD-movie-off-a-remote-server says youtube takes about 3.5-8 Mb/s
http://sonnati.wordpress.com/2011/09/15/bandwidth-is-running-out-lets-save-the-bandwidth/ says youtube takes 3.5 Mb/s though it wasn't clear if that was 720p or 1080p

I downloaded Netbalancer to figure out how much data streaming 1080p clips on youtube uses.
I tested 10 different clips from various users on youtube including videogamedunkey and cinemasins and found regardless if they are 1080p 60fps or just 1080p the clips used 660 - 680kBps equivalent to about a 5.5megabit connection.
I'm not sure how youtube encodes but that speed was close to my ADSL connections max speed.
720p used anywhere between 320 - 370 kBps equivalent to 2.75 megabit
By defintion 1080p contains 2.25 times more pixels to 720p so this is pretty close - maybe youtube uses better encoding for 1080p.
Hope this helps.

Netflix streaming movies - What kind of load should I expect on my service (in gb) for an average movie? I have Comcast and have a pretty healthy limit, but I don't want to start pushing it.

A discussion about this very topic here pegs it at about 1 GB/hour, which sounds about right for 'HD' content.

Wow..well, I shouldn't be surprised. It is a lot of data coming through the wires.

In a recent AskMe question, bitdamaged estimated the high end might be up to 1.7GB per hour, and the thread disillusioned linked to cited a movie that was 3.1gb for 1 hr 42 min, or roughly 1.8 gb per hour.

1 or 1.5 gb per hour for HD is also consistent with iTunes downloads I've done. The non-HD stuff I've downloaded has been more like half a gb.

Netflix said recently their HD is 4800 Kbps, which is 600 kilobytes per second, or 2.06 gigabytes (GB) per hour.
Assuming you get the max stream, that is. But if you're maxing out quality, 2GB/hr seems like a pretty good estimate.

BTW, that makes it about the same as YouTube 1080p (which is around 4096 Kbps). Not sure about Hulu/Vimeo/etc.

be careful, too many downloads and comcrap will cut you off.
That is one of the reasons that I am asking, actually. Comcast and Netflix have also been at each others' throats as of late and I don't want to get caught up in that.
I think I will stick with my mailed dvds for now.

I have comcast, and I believe there's a 250gb/month cap. You should be able to check your usage by logging into your account at comcast.net and clicking on users and settings near the top

Not an answer to your specific question, but relevant to your concern -- FWIW, Comcast's soft-cap is 250GB, so you do have a good number of movies you can stream (depending on what else you're doing, of course).

If you have multiple computers using the same Comcast account though, it can be really tricky estimating usage, especially if one of the users is a gamer or torrents. I try to use Speed Download for everything I download online so I always have a ballpark idea of how many GBs I've consumed. Speed Download let's you know how much you've used per day, per week, and per month; after that you can factor in the rest of your household's usage. I don't think it would be of much help with Netflix since you're streaming, but at least you can track your upload and download usage on other sites, then factor in about 2GB per hour if you stream via Netflix.

If you're concerned, the best way to monitor your bandwidth usage is to install a custom firmware on your router. DDWRT and Tomato both allow you to monitor the total traffic in and out of your router.

If you log into Comcast's website, they will show you your current and historical bandwidth usage, and how it compares to the monthly cap. Even when I was watching a ton of Netflixed Angel I never hit more than 10% of it. But I have the lowest-end Comcast plan where I max out at 175KB/s or so. The responses above are assuming you have at least 600KB/s sustained bandwidth which may not be the case. (Comcast's website seems to advertise burst bandwidth numbers only, which is confusing.)
But in any case, paying attention to your metered usage on your account page should be sufficient.

Yep, you can check your usage at Comcast's website. Over about 2 weeks in December I watched 2 seasons of Lie to Me (35 episodes, about 45 min each) on Netflix watch instantly, and my husband was playing online games on the Xbox the whole time. My usage for the entire month of Dec was 31GB.
