I have some windows media video files in 756kbps. I do re-encode them to mpeg files thru Tmpgenc. But, I dont know what bitrate setting I should keep for the sound and video files so that the quality is best but still
the files are not undue large. My question is like this :
756 kbps wmv = xxxx kbps mpeg1 or mpeg2
What should be the value of xxxx here ?
MPEG-1 is 1500 kbps CBR [Constant Bit Rate] and cannot be changed. Well, you could change it whan you make a KVCD (a VBR VCD), but isn't so relevant to know that they exist (we're speaking of low-quality stuff)...
For MPEG-2 you can go up to 2500 kbps VBR [Variable Bit Rate] for SVCD or 7000 kbps VBR (or even more) for a DVD, but since you start with a 756 kbps WMV I don't expect great gains in quality by moving from DVD to SVCD or even to VCD (garbage in = garbage out).
I use non standard mpeg at whatever bitrate I want to. Secondly, if I copy just the mpeg file to a cd or dvd like a data file, even then my dvd player plays it fine. If I use a cd/dvd author prog. it takes more space. Well this is a diff issue.
You are right in suggesting I stick to VCD quality mpeg. But, I use a higher bit rate for video and keep audio bit to low 64kbps only. This works fine for me.
But, still I come back to that elusive answer since I can keep the mpeg at any bitrate. This is like this :
1000 kbps wmv = xxxx mpeg = same quality
and 1000 DivX - xxxx mpeg = same quality
Of course, the answer would be tentatively. Both DivX and wmv compression is much better than mpeg.
2nd part of my query is :
the picture on TV is flickering though the clarity is good.
I tried NTSC, film and PAL mpeg output. All are flickering.
Any help on it pls
