Any decent encoder can hit a target bitrate (with 2pass), but still spend the bits intelligently to achieve similar quality throughout the file. x264 2pass figures out what CRF will give the desired bitrate (pass1), and then uses it (pass2). (source: Dark Shikari. cf. the links I dug up for my answer on this question about VBR streaming). You only get ...

Players buffer streams. The bigger the buffer size, the longer window the encoder has to use higher bitrates for hard content, and then fewer bits earlier or later on easy content, to achieve similar quality for the whole video. I'll assume you're going to use h.264 (aka AVC) as a codec, as it's the de-facto standard for streaming video on the Internet. ...

Yes, you have the right idea. If stib's suggestion of making multiple outputs in parallel with the same ffmpeg commandline doesn't quite do the trick, then use a temp file to hold a lossless copy of the output of any slow filtering: ffmpeg -i src.mkv -vf yadif=3:1,mcdeint=2:1 -c:a copy -c:v libx264 -preset ultrafast -qp 0 deinterlaced.mkv (never use ...

I've tried a bunch of front ends for ffmpeg and finally settled on Tencoder. Widows only. It has a preset for ProRes and is very easy to customize so you can crete setting for often used formats or settings. It is multithreaded and allows you to do batch processing.
