    I encode with ffmpeg in h264. I know 720p movies at 4000-5000 are very good looking on a "medium-sized" TV. But for movies encoded at 1080p 4000-5000 ? My storage is limited at the moment and I don't notice a significiant difference : Movies encoded at 1080p 4000-5000 are good looking to me. Of course, 1080p at 8000-9000 is the best...

    Your opinions, recommandations ?
    Are 1080p movies encoded at 4000-5000 good looking enough for you on a "medium-sized" TV ?

    Why not encode with H.265?

    I'm not a compression guy. I've wanted to make a T-shirt that shows a clamp with a red circle and line through it that says "NO COMPRESSION."

    The 40Mb/s bitrate of Blu-ray is more than tolerable, and it looks fine to me. Netflix can do almost half that with 4K HDR, and that "generally" looks OK to me. In truth, both are 8-bit and the lower color bit-depth bothers me in some cases almost as much as the bitrate (two different things).

    4K Blu-ray can hit 100Mb/s, plus they can do 10-bit and even 12-bit color, which is a good thing. If I'm archiving a copy of a movie, I try to do it at the least-intrusive codec I can. We generally go with ProResLT, which is 45Mb/s and 422 10-bit color, and it's kind of a "minimum acceptable quality" to me.

    To me, hard drives are cheap. I just say, "use less compression and buy more drives."

    As said above...storage is cheap.

    NVidia GTX 750Ti ... Fantastic card but no HEVC. :(
    So, external SSD ? I have already lots of USB sticks. :)
    Old Ivy bridge motherboard but "If it's not broken don't fix it". :D

    If its just movie storage then external HDD. SSD wont give you much benefit for the cost for just dump storage.

    A 4TB external will set you back around $100. Might want to get yourself a USB3.0 card if your machine has no USB3 ports. I would have thought it does however.

    If it's important stuff I'd get a USB3.X RAID1 enclosure . Two mirrored drives so if one fails the data sits on the other till you replace the bad drive and clone it back to the new one. It's not backup, just redundancy. 2x4TB HDDs in RAID1 will give you just 4TB of storage. Don't go RAID0!

    External spinning hard drives have never been cheaper or had more capacity. I routinely buy 12TB and 14TB for all our stuff these days. I remember too well the days when a 2GB (gigabyte!) drive was $2000 back in 1995. Now, 12TB is $200... and that's a huge change in less than 25 years.

    If your playback equipment can support H265, upgrade your GPU to something that does Turing NVENC (like the RTX 20/30 series or the GTX1660). H265 is supposed to be more efficient so it should look a little better at the same bitrate.

    You'll just have to wait another 3-4 months to get one or pay a 50% premium! :laugh:

    ffmpeg is an amazing piece of software... I use -b:v 9M for 1080p.. but I have external hard drives sitting around so I have plenty of storage capacity.

    Red alert, an encoding specialist is finally here! lol

    -b:v 8M for an imperceptible difference in my opinion ...

    You're welcome to comment at 4000-5000!
