Hi!I'm currently trying to encode a 146 minute film.I'm using the x3 template with TMPGEnc,but have set the output res to 352x480 and reduced the CQ to 30.
Would I be better off with a lower res template and a higher CQ rate?
I wanna fit the whole thing on a single CD-R which might be a bit ambitious,but if you aim for the stars you can only fall to the moon etc.,etc...

CQ at 30 ???? Don't you mistake with CQ_VBR ?

Anything with a CQ lower than 60 is barely unwachable.

A big YES !

It's weird that you have to use so low CQ for a 146 min movie.
Is it fullscreen ? Do you use an avisynth script ? (if not, you should !).
What audio bitrate did you choose ?

Note: please reduce the size of your avatar, it's unreadble on 15" monitor.

Made my avatar smaller now...
...TMPGEnc shows "MPEG-1 352x480 25fps CQ30 Layer-2 44100Hz 128kbps" and the output .mpg looks to be 700 Mb.The film runs for 146 mins.
Any suggestions?

You can enhance a lot the quality by using an avisynth script.
Nevertheless, if you movie is 4:3 fullscreen, then you don't have have choice than using a lower resolution.

Note : your source is PAL and you convert it into NTSC. Are you aware of that ?

Thanks,I see what you're saying-I'l check the quality of this encode,then probably retry with a lower res template.
What settings would you use for a 146 min .avi?

ouch. I think I anwser to all the questions but you don't read all my lines

Fullscreen + 146 min = use a script and 352*288 as resolution !

and ...x480 if NOT a valid resolution for encoding a 25 fps ! This is a NTSC resolution.

Are you in PAL or NTSC land ?

Oops!You're quite correct-I'm not using a valid resolution for PAL(I'm in UK)...Will try with lower res template and correct PAL dimensions as you suggest.
Have never used avisynth script before,but will investigate this as well...

Thanks for all your help so far.
I finally got a good result for my 146 min film using standard 352x288 template and a CQ setting of 64.
The whole thing fitted on a normal CD-R 80 and is of more than acceptable quality.
Great!
