video bits per second

[xviddivxoggmp3]

i've seen in this forum people that say you need to calculate
bits per second with video in multiples of
*8
*16
*32
what could happen if i try use multiples of *32 and it was too big for my cd by 4 mb. would it hurt the video if i encoded it with the multiple of *8 that is close to that overall *32 sum?
it breaks down with a decimal when devided by *32, but hits a perfect whole number when devided by *8. i've never done this before? i'm despirate to have it fit, but unwilling to loose quality.

I think you are mistaking 'bits' for resolution. The above case is true for resolutions, but definitely not for bits. I've always been using a variety of bits without encountering a 'bit-related' problem.

resolution?

explain more on resolution.
i just try to make sure the resolution fit the clipping perfectly?
does it have to be in a special size?

That's basically the size of the video (at 1x size, no zooming in or out) you see on-screen. For example, a video can have a resolution of 640x480, 512x384 and so on. Notice that the numbers are divisible by 16 (I always hold onto this theory).

DivX requires that the resolution is of a factor of 16 (or the other numbers you put as well). Otherwise, the result is a video that is not viewable at all.

not viewable?

does that prevent the filters from showing on a media player or the actual tv's?

[Enchanter]

Try it out. The result will be so bad it's not funny anymore.

Who had ever problems with wierd resolutions? I encode with a width of 640, 512 or 384 and make the calculated hight dividable by 2. I use DivX3.11 or M$MPEG4v2 and had no problems on any computer. So which computers will have problems if I use hights/widths not dividable by 16?

[Enchanter]

Did not explain myself clearly enough. I said that I always make sure that my resolutions are divisible by 16 and have always used that for my resolution basis. I know that there are other usable factors as well, but I have nothing against using 16 in the first place and it looks perfectly alright.

p.s. Strange resolutions would be those odd numbers.

[xviddivxoggmp3]

perfect

tried both mbs change and resolution outside of *16.
no difference.
good quality all around.
what could this mean?
