Hi, I'm using ffmbc in libquicktime to do prores encoding/decoding, I'd rather use ffmbc (better format support). But the libquicktime codecs require a newer version of ffmpeg than ffmbc is currently tracking, is this likely to change in the near future, if so any idea when, obviously ffmpeg has support now for a few things that ffmbc doesn't, and would be nice to only have to deal with linking against ffmbc.

I agree with Baptiste that ffmpeg is a bit mess and syntax is changing too often. The ffmbc looks very stable and easier to use compared to ffmpeg.
Sometimes I need to convert from file formats not supported by ffmbc
but ffmpeg did open thoose. Can't remember what exactly, but it did happen several times.
Should start keep a list on theese.

What is particularly bloated? Is it mostly stuff from merges?

-chunk_duration.
I find the default interleave on ff* produces jittery mov's when played back in quicktime/FCP, however by remuxing in ffmpeg using the above I can get an interleave that matches native QTPro coding and plays OK.

I never experienced that. Your computer is probably too slow ;)
Nonetheless it could be an interesting feature
- Metadata handling. There are plenty issues/bugs with 0.7rc7 .Using Metadata with FFmpeg is flawless (most certainly from 1.0 and upwards) - Up-to-date filters - Alac (and FLAC) codec up-to-date with FFmpeg

Metadata: There are a lot of inconsistencies. For example using Album performer does change different metadata in different codecs. Look at ffmpeg, it does it correctly.
Filters: For example the audio syncing filters.
Why I do not use FFmpeg? Well, FFmbc has support for several pro codecs (FCpro), can add APIC (pictures) to mp3, aac, alac, .. , ..
What's "Album performer" ? Album artist ? It works well in Quicktime/iTunes for mp3 and m4a.
If you are referring to ogg/flac then it could be buggy but I don't think I will fix it unless sponsored,
I will accept patches though.
I don't think audio syncing filters are needed currently, -async works well.

sorry for the confusion, wat i wanted to suggest is transcoding from any format to an Avid compliant set of OP ATOM audio and video files maybe with a command like "-target imx50 -f avid"
