OK, someone keep me from pulling out what little hair I have left

Handbrake not working concerns me, but I'd almost certainly say FFMPEG will convert any video format you have on that DVD. It's just not real user friendly to start with.

 

And if VLC will play the disk, it can most likely be able to convert/export that video as well.

I'm with Jason rip with makemkv then transcode with handbrake.

 

Granted my setup where I rip the movie distribute each chapter to separate computers with gearman then transcode and paste back together in mkvmerge. Got my high profile mkv conversions from DVD down to 10 minutes or less.

 

Helps when you have 3 quad cores to throw at it as well.

 

No idea what my watt draw is but have electric heat and try to mainly do this in winter lol.

Ben Reese I still am not aware of a gpu encode that looks as good as a cpu. I think handbrake is trying to use gpu components for parts of the encode but gets moderate boost at best. I think Intel quick sync is the latest and greatest gpu encoder last I checked.

 

I was looking to the future of maybe encoding 4K h.265 some day. Most of my h.265 testing showed 20% compression improvement vs 1080P on high profile h.264 but encoding time doubled.

 

Also it was pretty fun to do.

Benjamin Webb I guess I wasn't aware that CPU encoding was much different than GPU encoding. I've been using Blender for a few months and finally found a build from 2012 or something that works with my 9 year old graphics card for rendering. Videos come out exactly the same except they're done in 4 hours instead of 15 like they used to with CPU rendering. 10 minutes would be nice...

Ben Reese Video encoding an already compressed video is way different than rendering.

 

The raw master from the studio is on the order of a couple terabytes. They then compress the colors to rec709 and to 1/4 resolution of 1080P while the black and white portion is brought down to 1080P. From there it is compressed further to fit on a blu-ray. The 30 gigs they use there is on the order of 2% of the size the original master.

 

For digital theaters they compress the colors to fit as P3 and keep it 4K (not UHD) and end result is about 200 gig.

 

We then as the bastions of quality take that 2% or possibly even less with DVD then compress it even further. The main problems typically occur with gpus at fast motion getting blurry at this point in detailed action films. They probably would not be a problem except for the 24 fps framrate (23.97). If you give the gpu encoders more bit rate resulting in a larger file size they handle it fine as well.

 

I also use the same setting for everything I encode to make sure motion looks good and adjust rf of blu ray 's DVD as DVD you have less to lose.

 

So yeah with a man-made render I doubt there is a difference as it is way less complicated then trying to film real life. Anything CGI compresses way better. What takes the most bandwidth to recreate is the film grain from my aliens blu rays lol.

 

Here ends my video quality rant.

Kind of a long story. Got into recording with TV tuner since before windows media center was a thing. Got into hacking original xbox with XBMC as was cheapest upconverting DVD player and could play xvid files like a boss.

 

Made a name building home theater PCs for rich people and even wrote some articles with Tom's Guide. I noticed that PCs did not look right when plugged into high def TVs as they were not converting to REC709 correctly from RGB on the older TVs so learned quite a bit about HD standards.

 

I even made my own operating system out of ubuntu for HTPCs that is now defunct.

 

From there I got into surround sound and am actually more passionate about that than the picture quality as sound has absolutely gone to hell in rescent years while most TV sets are pretty dam good if you stay away from vivid mode. People with Bose and cheap sound bars make me cringed but still better than internal speakers. Have set up plenty of high end sound systems.

 

Now spend most of my time as a Chemical Engineer but still keep up to date with AVS Forum and watching home theater geeks. They had a professional video encoder on who described how crazy the amount of compression required is in a blu-ray so I thought I would share.

 

As someone who made lots of money as side work as the transition from analog to digital video and then the transition to HD

 

I have learned quite a bit. In my search to create the perfect home theater setup is where I learned networking, raid arrays, etc. I generally only apply my skills to my own stuff lately but am definitely willing to share.

 

I remember taking two days to convert a DVD to xvid so I could store it and play it with a hacked xbox running XBMC. And I have probably made just about any mistake possible when encoding stuff to even get that far.

Benjamin Webb?, that is a bio I think a lot of people around here wish they had.

 

I have to say currently audio interests me more than video these days. I am the type of person that needs audio to make it through the day. I am playing around with the thought of building the equipment to zone out my house so wherever I am it's never silent.

 

Have you watched Mark Smith?'s YouTube channel? He is currently building a headphone amp.

Yeah never been a headphone guy as real bass is impossible. Should feel the snare drum in center of your chest if dialed in correct.

 

Suggest Logitech media center with a raspberry pi with a hifiberry and a t amp.

 

Can go the Chromecast music route as well I believe but have not tested it and wonder if it works with lossless.

I think I am going to be trying a a Chromecast. I never really thought of a hifiberry I am going to have to look at it. I have also been looking at the Lepai amps they seem decent.

 

Whatever route I take I know I want it to live in a rack in my basement. All the speakers get wired back to there.
