Is there a possibility to...mark certain timespaces to maximize the bitrate

Hi, I'm in the basics of video encoding for quite some time and since I got myself new video material to encode I would want to jump onto the next stage now. A few days back I tested the DivX7 release and was - as everybody else - very disappointed.
I basicly handle the encoding of drawn things like little cartoons and such and so I wanted to know if there is a programm that allows the user to scroll through the film and mark certain timespaces to maximize the bitrate at.
I ask that questions because no matter what I tried when I wanted to have a second version of the film/clip with not more than 1200kb/s it comes to macroblocks. Even if I put more P and B frames in.
That especially happens when there is a tracking shot from the left to the right or from top-down.
Is there any good setting or program I can prevent that from happening with a bitrate around 1200 or is it essential and inevitable to increase the bitrate!?

I would be most grateful or an answer!

You can use "zones" to encode with x264 in MeGUI (e.g. use 1200kbps average bitrate, but for the credits use a lower bitrate, and for complex scenes stipulate a higher bitrate e.g. frames #100-500, this is done with a preview so you can demarcate the sections). You shouldn't have to resort to this, I suspect something else is wrong here, either with your source or settings.

If you are not fixated on a certain bitrate/filesize (e.g. 1200kb/s), you can use constant quality encoding instead (CRF mode), which is faster (1 pass instead of 2), but the ending filesize may vary

Settings are important , as you would definitely use different settings for an anime style cartoon vs. a grainy movie like "300" or CGI style material. Fortunately MeGUI has presets profiles that you can use

There is default inloop deblocking with h264 that should take care of most common blocking scenarios at lower bitrates. The macroblocking shouldn't occur at all using h264 with 1200kb/s for SD frame sizes under any circumstance, unless your settings are bad (ie. deactivate deblocking), or your source material already features prevalent macroblocking (in which case you might be able to do some pre-processing/filtering). The other rare situations are when using VBV buffer during fades, (but there are workarounds to that situation) , and sometimes container issues (sometimes swapping containers e.g. from .mkv to .mp4 fixes it), or playback decoder issues (e.g. you have bad settings like deactivated deblocking)

Finally, if you post a small sample of the source which replicates what you describe to a free hosting site (e.g. mediafire.com), someone here can have a look at it and suggest possible solutions

I changed the subject so it actually says something about your topic. You can also adjust by click on edit on your first post.

the only encoder that comes to mind that might help is cce. but it only works with mpeg-2. it allows an unlimited number of vbr passes. on every pass it re-allocates bits to the scenes that need them more. i've used it on animated movies at up to 9 passes to get the look i was looking for.

for an avi - i would use h264 mp4 and increase the number of reference/key frames to an acceptable level and use a deblocking filter. sorenson squeeze might be a good choice of encoder.
