Hi All,
I have been experimenting with transferring my DV footage to DVD and hence my questions over the past few days...
Here is another issue I am having --
When I max out the bitrate (in VBR mode) to 8 Mbps, In my resultant MPEG2 file, I am seeing the bitrate at times spiking well over 8.8 Mbps...thereby making my overall muxed bitrate well over thee 9.8 MBps...This is causing some issues with playback on one of my DVD players (other players seem to be more forgiving!)..I get a sort of a beep whevever the bitrate is over the limit on this JVC player I have...
For the completist -- here is the scenario:
MPEG2 compressed with VBR, Q set to a 1 (I want the program to give better picture quality over compression) and Avg bitrate to 7 Mbps and max set to 8 Mbps. The audio is PCM, 48 Khz, 16 bit Stereo which PowerDVD in the final DVD image reports as 1536 kbps...
So, the math dictates that by over muxed bitrate should not exceed : 8000 (for video) + 1536 (for PCM audio) = 9546 kbps, which is below the max! However, as I stated about, sometimes the bitrate spikes over that mark and i get those beeps on my JVC player(which is perhaps a stickler for standards)...
What can I be doing wrong -- What I have done is obviusly reduce the max and avg. bitrate and I am fine, but I want to use the max 8000 bitrate if I can...
Help!
