minor correction it's video lag instead of adui lag as mentioned in original post.
audio leads the video while playing in free players. -
you need to post whcih you've tried
have you tried VLC?
also virtual dub with the plugin -
i hv tried all free players the can be found here on VideoHelp including VLC.
one thing i hv noticed now is PD shows correct total playable time is 7min 48sec while media info reports it to 5s 5ms which is wrong.
i just down sampled to v=9000kbps and it works fine in almost all free players i v tried before. -
I assume that this is a MKV? You could try changing the framerate to 60000/1 in MKVmerge and see if that helps. I don't know why MKVmerge has so many sync issues when you add elementary streams, even when you set the framerate to the correct framerate.
I had a music DVD today that I tried to convert to MKV. It was supposed to be 4 minutes at 29.970 but it ended up 8 minutes at 29.970. Changing framerate to 59.940 made it 4 minutes and it played correctly in all players.
36.9 Mbps is a lot for a SD file though.
