The same problem at about the same time on every AVCHD disc

[mahogany]

One day I burnt out an AVCHD disc. On my PS3 the video on that disc plays back smoothly, no any flaws at all. On my friend's regular BD player (Samsung) the same disc plays back with some flaw (skipping, video hangs on). So I thought it could be a defective disc and (just out of my curiosity) I burnt the same video out on another blank DVD disc. To my amazement the same flaw had appeared at the same spot/time on the disc as it were playing on my friend's BD player. Amazing !!! Despiting a common sense I have bought another pack DVD's and burnt the same video again. Checked on my friend's BD player and... same problem at about the same time of playing back of the AVCHD disc. That's weird and interesting Why

Not all players support AVCHD, and those that do don't all support it equally. There are restrictions on how a disc may be authored, what bitrates and encoding parameters may be used etc. Bottom line : there is no way to guarantee that the same disc will play happily on all AVCHD compatible systems. Something in the way you have encoded or authored your AVCHD disc doesn't agree with the Samsung. This is one of the reasons MultiAVCHD has so many possible output options.

Recently I've put this AVCHD disc to play in my PS3 and push the >select< button to see the bitrate rate. About the time when video gets the problem on Samsung BD player I see very high bitrate (the highest I've seen there is up to 31Mbps). Comparing to the rest of video/timing where it plays back smoothly I can say it is extremely high bitrate.
Could it be the matter ? Very high bitrate in comparison with the rest of the video which plays smoothly ?

[guns1inger]

That would do it. I have no idea how you created this disc or encoded the material, but I suspect that Samsung has a much lower threshold for bitrate than the PS3. The solution will be to re-encode at a lower average bitrate using an encoder that has better control over spikes.

Thanks again for the answer
Okey. Maybe do you know about which program/encoder would be good for this

[guns1inger]

What did you use to create the disc you have ?

[mahogany]

multiAVCHD

[guns1inger]

What was the source ? Was it already AVCHD compliant, or did you have to re-encode it ?

The other tool I have used successfully is AVCHDCoder. It is simpler to use if you don't need the menus and more advanced functions that MultiAVCHD provides.

[mahogany]

Sorry for my vague answer. Before that I have re-encoded in order to make a small file. I had used MeGUI then.
Yes, the video was AVCHD compliant before.

The original AVCHD 1440x1080i h.264 camcorder format was 16 Mb/s CBR, later expanded to 1920x1080i 24 Mb/s CBR. The HDV MPeg2 25 Mb/s CBR format also usually works in the AVCHD file structure.

Players vary but these are the formats they are targeting. Keep in mind that the higher the bit rate, the faster the DVDR disc must spin. Extreme VBR may cause a buffer overflow.

I had a similar problem when I started making AVCHD discs, tried everything and nothing fixed it. Then OPPO did a firmaware update on my player and everything has worked great since. This could be your problem. Samsung may need to tweek firmware.
