About Bitrate

Post by metalfex »

currently using tmpgenc and added 2 audio streams for a project (1 is dolby and other is lpcm), when clicking on simulation i get this message "track is too high for a dvd-video. the clip current total bitrate is 11228kb/s however in a dvd video the clip total bitrate should be lower than 9848 kb/s"

so in this case i go to settings and change my lpcm audio stream to dolby digital and make it 128kb/ps... however now i dont have loseless audio anymore :( does anyone know how to solve this? I mean i can still continue and make the dvd there is that option but ive never tried it, is it safe to still make a dvd with like 11228kb/s?

ive never tried dvd lab pro so i dont know if it will give me the same message.

Have you tried to use Bitrate calculator to calculate videobitrate and audio when you do your stuff? About the bigger bitrate it's not standard dvd anymore so it may not play in all players. Besides higher bitrates are actually "more harmful" then lower bitrates because the player has to add more stuff to it's buffer and with small buffers the player can't handle that overload of bitrate.

Do a new rip with calculated bitrates.

what if the dvd is already like that im just adding menu/chapters and 2nd audio source to it? should I then lower the video bitrate? also does lowering the video bitrate have any effect on the quality? I mean like will it become grainy and not so sharp? thanks

You mean you'd re-encoding it?

If you have great mpeg-2 encoder you don't need that big bitrate. But many might say that when you re-endoce mpg2, it adds another generation, so to speak. It all depends how good programs you have also in what resolution you do it.

hmmm well what i did was i changed the audio from pcm to dolby digital @ 320kbps and that seemed to solve the problem, its only one audio stream now
