I am considering, for my delivery method for the video files, to transcode from my DVD rips to a format that will play back in a modern web browser, becuase I can be reasonably certain that everyone will have a modern web browser.
I kind of hate this idea! But I can make small vp9 videos that I can guarantee most users can play back, and also I can include an index page with info about the videos and history and stuff.
This is the most efficient way to do this I can think of.
I'm open to better ideas though! Technically I could use MP4, there are patent concerns with h264, and h265 doesn't have as wide of support as VP9.
I haven't tried to ship digital video via any mechanism other than a web browser or a torrent, ever. If I'm shipping video via a torrent, I can be reasonably certain that the recipient has VLC or equivalent.
I can make no such assumption about this project.
@ajroach42 Please don't use VP9, it rules out playback on a lot of devices.
MP4 is probably the best choice, most widely supported.
@thomasfuchs I'm not sure what your comment about DVD quality is supposed to mean.
My goal with using a more efficient codec is a reduction in file size. I'm trying to maximize the 2GB of storage I'll have available for delivery.
I keep my mpeg2 master files in cold storage and transcode hevc copies for personal use. I do a lot of this stuff for personal use, and I know how to do it correctly. My concern is mostly about making things usable for non-technical folks.
@ajroach42 well, the original encoded MPEG2 streams on DVDs aren't the greatest and who knows how they encoded it and what the source material was like :) MP4, even with lowish bitrates shouldn't really make it worse.
@thomasfuchs oh. I have to disagree with that pretty strongly.
The original mpeg2 streams are often garbage, but the original film sources are also often garbage. A low bitrate h264 transcode converts that film noise to smears and blocks, makes the resulting movie almost unwatchable.
The difference in file size for my minimum threshold of acceptability for a noisy film source is 2:1 from h264 to h265, and about 1.6:1 from h264 to VP9 in my test so far.
@thomasfuchs ffmpeg, 8 times out of 10.
I've dabbled with other stuff, but I keep coming back to it.
@thomasfuchs I watch a lot of low bitrate mpeg2 from noisy film to low bitrate MP4 files.
Like, a lot.
I have a device that I basically use exclusively for playback of low bitrate MP4 files.
I know how far I can push the format (and it's about half as far as I can push hevc, too bad it's impossible to get hevc playback on my palm pilot!)
