24 FPS with Higher Visual Quality or 30 FPS with Lower VQ?

yeah . ( just thinks of how it would actually look if it were both 120 fps and hand drawn and Hi-bit rate if it was about a series that you loved ^_____^ )

Seemingless Motion - A frame rate soo fast
that details of the movements are not possible - everything is happening soo
fast that it looks like your viewing a Crystal Ball or real life instead of this
frame by frame jerkyness that 30 frames per second gives.

True Liquid Motion AMV's that are so real, your Monitor becomes a transparent
fish bowl instead of just another TV set.

If he has to set the bitrate to say, 1200kbps in order to get a 50mb file, it doesnt matter if he encodes at 29.97 fps, 23.976fps, or 120fps! They all require the same bitrate to achieve 50mb.

Okay, so the BITRATE is the same. But the QUALITY of each frame will be somewhat better in the 23.976 version, because there's fewer frames over which to spread those bits, right?

Ok. That was what I was getting at. I forgot that the bits per second did not change. Instead, the quality per frame is what gets bumped up a notch.

Seemingless (seamless?) Motion - A frame rate soo fast
that details of the movements are not possible - everything is happening soo
fast that it looks like your viewing a Crystal Ball or real life instead of this
frame by frame jerkyness that 30 frames per second gives.

True Liquid Motion (fluid motion?) AMV's that are so real, your Monitor becomes a transparent

Ok, slightly better, but you still need to work on your english... I mean it man, I'm sure that you are a very intelligent individual, but until you begin to express yourself more coherently, you'll not be taken seriously.

scarbroiled... he needs a snickers ;-p.

(as do I cuz I still don't understand what was talked about here... :shock: think it's CBR vs. ABR and what not just confused and torn through holes, given holes and plugged up...)

23.976 FPS is stupid. Use 24 FPS.

No, 23.976fps is NTSC FILM framerate. 24fps is not.

I think maybe you meant "file size", not "bitrate". And actually, if you're going FROM ~24 TO ~29, it's not necesarily gonna make the file size any larger (well maybe a couple hundred bytes at most). Although that also depends on the program. For instance if it just decimates or copies frames (like when you slow down and speed up clips in Premiere) or if it does frame blending, like in VirtualDub (this is why it's always a good idea to never use Premiere to slow down or speed up clips, always use VD, it'll look smoother).

Each frameof a 24 FPS video has 25% more bits than a frame of a 30 FPS video at the same bitrate. Thus, if you lower the framerate from 30 to 24, your video will APPEAR to have a 25% higher bitrate - essentially, free quality.

..Shut the fuck up Mad Hatter, you DUMB FUCK. He means bitrate. Lower framerate = less bits spend = lower bitrate for same quality. Essentually, he means that the lower the framerate, the lower the bitrate has to be, rather than a file with a higher bitrate, it needs a high bitrate for good quality.

Um, it doesn't have any more bits per frame. Why would it? I mean, unless the frames were different sizes (ie 352x240 as opposed to 640x480). It might have more bits per second, since there are more frames per second, but as I mentioned before, that depends on how it's doing the conversion. If it's just duplicating a few frames, it won't increase in size at all. If it's using some kind of frame blending, then yeah, it'll increase.
