It will take me a long time to download and then upload, so I want to ask first, whether maybe the final product is a bit over-sized presently? If the video is occupying all that data space for good purpose -- excellent encoding with very nice high pixel count and frame-rate, for example -- then great, I'm glad it's a high-quality product. But if it's just a fluke of the video-creation process, that it has turned out to be so many Gigs, and they're actually unnecessary (?), then maybe someone else can re-render the video to reduce it to something of the same quality but with a significant reduction in file size? I do recognize that the original post here at Milovana is not from the video's actual creator, but maybe word can be shared somehow?
Anyway ... I will give it a download attempt, either way; and then it will eventually get to my Mega sharing zone, probably; but I can't promise speed, due to the size issue.
Yeah, this video (including the encoding) is entirely the work of Milovana user "Bodybuilder" who can't log in here anymore and uploaded this to
www.empornium.me. On empornium, his username is "Milovana".
The file size does seem a bit big, but I don't know a ton about video encoding best practices. I will say that in my observation, the file size is right on par (in size:length ratio) with most of the 720p movies I download from usenet that are encoded by the scene release folks. A 2 hour 720p movie downloaded from usenet will commonly be somewhere around 9 or 10 GB. I don't imagine the people who encode those movies would make them so big if there wasn't some quality to be gained from the size, so it seems entirely within the realm of possibility to me that Bodybuilder is using a similar encoding profile. If anyone really does understand the numbers, all of the video encoding details (frame rate, etc, etc) are listed in the 1st post of this thread. I will add that I've watched some of this CH video, and the quality looks very nice to me--it's definitely high quality 720p.
Regarding mega.nz and bittorent, I have a 1 Gbps connection from my ISP and the only file download technology that can come anywhere close to utilizing that speed is a well-seeded torrent. 1 Gbps is equivalent to 125 MB/s, so my maximum theoretical download speed is 125 MB/s minus TCP/IP overhead minus whatever the overhead of the protocol is on top of that (such as bittorrent). That being said, in real life, the fastest bittorrent speeds I've seen have been just over 30 MB/s. When I download from usenet, I get around 22 MB/s. From mega.nz, I've seen as high as 6 MB/s, but I'm actually uploading this file right now to mega.nz (thinking that then I could give the link to book_guy, and he could transfer it to his collection and make it available to everyone else) and uploading started out at around 1.6 MB/s and quickly slowed to under 1 MB/s.
So, I'll take a well-seeded torrent any day over other methods I've tried, at least when considering speed. Besides speed, the other primary factor is availability. In theory, bittorrent is good for that too, because it's distributed so doesn't rely on any single person or server, but that requires that at least a few people continue to seed the file (either by leaving it seeding in the torrent app on their PC, or by leaving it going on their seedbox). In reality, torrents often do become unavailable after a time because people don't do that. A file hosted on mega.nz may or may not have better availability, but for completely different reasons. If mega.nz went out of business or changed their model or policies, then the file could become unavailable, or the single person who owns the account it is being hosted from could remove it. However, in this case, if book_guy is hosting it, he has a good track record of keeping the files available, so that seems like a really good way to maintain an online repository of CH videos that can always be found in the same place in the same way.
