    I own a Panasonic DMP-BDT280 DVD player. When playing my own created 1920x1080 25i H.264 discs the motion especialy on pan shots is very jerky. The same files played in computer have beautifully smooth motion. So the player seems to be rubbish? Can anyone recommend a player which plays properly, and will also play 60p?

    what are you burning the h264 files onto? dvdr? bdr? if you are putting high bitrate h264 on a dvdr no standalone will play it well as the bitrate probably exceeds the max allowable on dvd. you'd need to burn them onto bdr to play smoothly. playing files on a computer has nothing to do with what will play on a disc. try playing the files off of a network drive or usb drive inserted into the player. those should work ok.

    That sounds like a really good answer. I'll try it tomorrow. Thanks.

  4. The player may be playing the video with the wrong field order.

    Why would it do that? I havn't got any BR discs at the moment so I can't test it.

  6. If it's DVD media, that's almost certainly the issue .

    The transfer rate is lower than BD media , the safe value for DVD media is <15Mb/s so likely you have buffering and transfer issues

    You have to use correct settings if your goal was to use DVD media

    A wrong field order issue would exhibit problems everywhere with motion, not just a pan . It would look like forward/back/forward back

    I'll never use DVDs again. Here's a related problem though: a BR disc taken from 16mm film at 24 fps plays with very bad motion, but it used to play OK on my old player. Presumably this player (the Panasonic) is no use for 24fps?

    It could be several things, but Panasonic players are known to be more finicky with homebrew discs (compared to retail pressed discs), than other brand players in general. Certain firmware versions might be better

    But it might be encoding settings problem , muxing problem , authoring problem , many things

    Also some players are known to be more forgiving, and play out of spec discs.

    Thanks. Can you recommend a good player which will play everything: 24fps 25i 25p 30i 30p 50p 60p 4k etc

    I don't know .

    UHD players are newer, and there are going to be a few revisions

    And there are always some compatibility issues with certain rare things

    HTPC if you want 100% everything playable, out of spec authoring, home made stuff

    Now I've bought some BR discs. But now it wont burn to disc. The file is a normal 1920x1080 25i file, but it says I/O Error! Synchronise cache failed. Reason: Write Error.

    First I tried to burn it at 12x write speed, then 2x write speed. Same for both.

    Does the player say that, or the software burning it ?

    What software are you using to burn/write ? Has it ever worked before with a BD disc ? Check for updates or check your burner hardware for updates such as firmware

    Did you encode the file to BD specs ? Did you author it ? or is this as a data disc ? What are you using for those and to burn ?

    the software says it. I use imgburn which worked perfectly well in the past with BR discs. This is a film, not a data disc. I authered it. I didn't encode the disc to BR specs, but I never did in the past and it burned OK. The discs are Verbatim 25GB.

  14. I don't know, bad batch of discs ? unlikely and Verbatim's are usually pretty solid

    How far off BD specs ? What is the average bitrate ?

    Some picky players won't play stuff if you're off a bit (not just bitrate, there is a bunch of other stuff that make it blu-ray compatible) even if it authored correctly and burned ok

    I tried exporting it from Pro as H.264 Blu-ray, but it still won't burn. Now it says Incompatible Format.

  16. Did you author it first ?

    An authoring program should reject incompatible streams , but cheap ones tend to let bad stream pass through

    Wow. Just wow. That answers a lot of questions.

    How about checking "what is DVD?" above.
