Suggestions on Converting 5fps to DVD

p@mast3rs wrote on 11/14/2004, 2:30 PM

Ok, I did a couple computer based tutorials and I used Quicktime .mov at 5 fps 720x480 (very little to no movement.). Foolishly, I deleted the source files but now want to convert these tuts to dvd.

Is there anyway I can do this successfully using the same frame rate or will I have to use multiple DVDs for 6 hours worth of tuts? I can fit all 6 hours of QT files on one CD and I am hoping that I can do the same for DVD video.

Any suggestions?

You will have to use multiple DVD's to fit 6 hours worth. The frame rate you rendered the QT files at is somewhat irrelevant to the way they are represented as MPEG2 format on DVD.

You could try to set the bit-rate of the MPEG renders down to something very small - and see if by doing that the quality remains sufficient for your needs.

If you use Dual Layer DVD's you may be able to come close to the 6 hour figure at a low bit-rate. Look for the many posts here related to bit-rate calculators in order to find out what encoding rate you might be able to use in order to fit such a long video onto a DVD.

My DVD player will play MPEG files at varying frame rates. I haven't ever tried burning a DVD with other frame rates though. The authoring software may always convert it to 24 or 29.97 or 25 when creating DVD-compliant files.

On the other hand, since there will be so little movement it may be possible to encode at an extremely low bitrate and still have useful images.

edit: Honest, Liam, i typed and posted my message before i saw yours. ;)

Thanks. Ill try that route.

you can fit 6 hours on a dvd 5 , but i'm not sure you can do it totally in vegas..

but i'll tell you how to do it ..

render the video to 23.976p+pulldown (if you are NTSC) , 1/2 D1 resolution (totally DVD compliant) (352 x 480 ) or to 352 x 240 pixels MPEG1 (Same as the VCD Standard) (also completely DVD player compliant)

render the data rate to be 192,1550, 3550 2 pass VBR if using vegas
or 4 pass at 0, 1550, 4500 if using CCE SP or 2 pass VBR 750, 1550, 3550 if using tmpgenc.

leave GOPs open , turn off alternate scan pattern ....
there is a bunch of settings really and i could write on and on ..

render audio to ac3 stereo 128 bit rate ..

Author this in a authoring software that can take totally compliant mpeg streams but outside of the standard 720x480 common resolution (in other words, not DVDA - though I understand their reasoning) .. TMPGenc DVD Author or MediaChance DVD Lab Pro are two packages that work and are low cost (and very good) ..

If you want to improve the quality more than above -- you will have to tweak CCE SP (expensive) and/or use KDVD settings.
