QuickTime Player and MPEG Streamclip should have worked if not for the codec. Did you try ClipWrap?

There is a very noticeable lag when using Compressor droplets on processor intensive media. It rarely crashes, but it will can take quite a few minutes for it to start working. It was better in FCS2.

I find Compressor even worse than droplets. Droplets lag. Compressor can get crashy.

Nope, ClipWrap can't do it at all.

That's interesting, because Videoblocks claims their smaller files are H.264. Obviously they are not. Maybe you should contact them -- if pro editors can't use their products without resorting to a spam-based, possibly unethical company like Pa*tube, it's really not a good sign.

Avchd/avc is h.264. But there are many h.264 profiles and some are more processor intensive than others.

It's just utterly bizarre that QuickTime Player and Compressor can't read the codec but Legacy FCP can. That never happens.

A very wild guess could be that there is an alpha channel attached to the movie. I've seen something like that on Animation movs. But it's just a wild guess.

I didn't know H.264 codecs could handle alpha channels. Is there one that can?

It's not a format limitation. Avid for example, stores alpha in packed YUV formats. There was an old workaround to avoid the QT gamma shift and it involved tweaking the alpha channel. Let me try mucking around with that to see what it does.

Does it have a damaged header? Sometimes QT repair can make things work more happily in QT.
