Image Sequences and Quicktime

[gary adcock] “that is not my opinion David- I can see a difference on my scopes between the 2 files, minor, but there none the less.”

Thanks Gary! That’s interesting to note. I just did a visual which looked pretty much identical.

BTW, what was really shocking to me was exporting from the targa seq. in QT Pro to a DVCProHD QT. Wait til you check that one out… Besides a huge gamma shift, there are major uglies as well. The gamma shift was really a big and unexpected surprise. Check it out if you get a chance and let me know what your take is on that…

THNX,

Yeah,
I will have a 10 page diatribe on DVCProHD vs ProRes in the next week or so. Shocking is an understatement, I have seen the light on using any camera native codec for anything other than Offline in my workflows.

Gary,

After evaluating frames from Greg’s original video vs. TGAs and a QT file made from those TGAs, it appears to me that the problem stemmed not from FCP, but rather from in-camera compression/interpolation on an area of semi-darkness in the BG. That area has visible artifacts right out of the camera, and any further compression, no matter how minor, simply amplifies those artifacts. Monitoring in the canvas dosen’t help either…

Oh, and I’m sure your diatribe will be an interesting… I look forward to it.
