Still images with transitions in FCPX not compressing properly in MPEG Streamclip
Hi,
I tried posting this in the compression forum but had no luck so I am hoping someone may be able to help me here! I’m working on a Mac, using Lion. I’m using FCPX (version 10.0) to put audio and still photos together. I then export the sequences into QuickTime using the Apple ProRes 422 codec. After that, I import the files into MPEG Streamclip to convert them into H.264, and again export them as QuickTime. I’m using the files in a web-based doc, so the smaller the file, the better. It has been working perfectly except for when I use the transition tool in FCPX to add cross-dissolves between the photos. This makes it so that for whatever reason, MPEG Streamclip doesn’t compress the files properly, the photos are all pixilated. Anyone have any idea why this is happening?
Thanks so much,
Nicole

So you’re going through three conversions to get to your final output? You’ll get much better results if you just go straight from the timeline to whatever file type you need. If you are looking for small .mov’s, then the Share > Email export may get you there.

Just to be clear…
The basic distinction between video formats is: Editing format v. Deliverable format.
Editing formats…this means each frame of video contains its own picture data, much like we think of film frames, called “intraframe.”
Deliverable formats…these are compressed. Video compression is pretty clever because it changes the intraframe into a Long Group of Pictures (GOP). The first frame of a Long GOP is an Intraframe (I). The next frame is a B frame.
So when you edit, you want to “unpack” the Long GOP into an intraframe codec, first! (Actually X does it for you if you push the right buttons.) Then edit.
Then compress your deliverable.
If you haven’t already, spend the $50 on Apple Compressor. There’s fancy algorithms which make the Long GOP compression look clean.
