Well the bitrate varies with resolution. If you are going for high quality videos, 7-12mb is good for 720p, and 12-15mb is good for 1080p.

You can adjust those lower for a smaller filesize.

If you want to target a specific quality instead of bitrate/filesize, then use CBR.

Going for target quality will be done with something like this command:
x264 --crf 24 --ref 6 --mixed-refs --no-fast-pskip --bframes 16 --b-pyramid --weightb --direct auto --subme 9 --trellis 2 --psy-rd 1.0:0.1 --partitions all --8x8dct --me tesa --threads auto --progress --no-dct-decimate --no-psnr --no-ssim --output video.264 input.y4m

You only need to make one pass when targeting quality.

Basically, I'm looking to put up a video or two and a good balance between filesize and quality would be nice. I'll try playing with the options more later. :D

ViciousXUSMC,

i can make hd youtube clips just fine, but they still have the left/right black bars: ie: http://www.youtube.com/watch?v=RtufoeWM624&fmt=22

i am guessing this is because my resolution is always (so far) 1920x1200 instead of 1920x1080 like yours.

i don't really want to use a lesser resolution then my native monitor res.
how can i have full hd clips on youtube like YOU with no f*ing left/right black bars ???

using agk i tried several widths and none seem to do it once uploaded to youtube. i always have the black bars.

HELP!!!

:x :evil:

It's because YouTube only supports up to 720p (1280x720).

This means that if you use 1920x1200, it's going to downscale it to 1152x720 to fit in the 720 height. The only way to fill the whole frame is use a 16:9 resolution. You can either crop your 1920x1200 down to 1920x1080, or record straight in 1920x1080. My monitor is 16:10 and I leave it at 16:10 while playing the games, but when I go to record a video I will switch it to a 16:9 resolution.

so what is the EXACT resolution of the avi file that one needs to upload to youtube so that there are no black bars on the left/right ? is it 1152x720 ?? shouldn't it be 1280x720 ?? BUT i have uploaded a file that was exactly 1280x720 which was converted with agk from a source of 1920x1200 @16:10 ratio from within gta4 and using fraps...

I assume any resolution less than or equal to 720p, with a 16:9 aspect ratio. dopefish said 1152x720 because that would be your video downSCALED (still at 16:10) to a resolution height of 720.

Perhaps your software is adding black bars to achieve your 720p?

It needs to be any 16:9 resolution, 1920x1080, 1280x720, 1440x810, etc.

YouTube is going to downscale it to 1280x720. Uploading in a higher resolution will result in a better output quality by YouTube.

Are you sure the software didn't downscale it to 1280x800? or 1152x720? YouTube will automatically add the black bars to fill out 720p.

whoa wait, so now it has to be 16:9 AND 1920x1080 ??? wth ??
i checked all resolutions in gta4 and the 1080 is not available.
nah, something's not right. i do not believe that people who use 1920x1200 can NOT make proper full youtube vids... i'm getting mixed messages here....

It doesnt need to be, Just to take full advantage of youtube (no black bars) it needs to be 16:9 yes. 1080 would be the best for you as its nice and snug with your native resolution of 1920x1200.

I have to disagree with dopefish though, I would personally record everything in 1280x720 though, No scaling. Do you have any sample videos to support the claim that scaling downwards on youtube is better than no scaling?
