David,
“Precisely why I said that uncompressed video is kind of a misnomer.4:4:4 RGB is in fact the only truly uncompressed video.”
Absolutely. 4:2:2 is really, really, really, good compression that for the most part might as well be uncompressed. But it still is discarding data in the process and would eventually show degradation if you transcoded it enough.
This is a lot like the ‘is Pluto a planet’ argument but…
Let me throw some gasoline (petrol) on the fire by saying that 4:4:4 RGB is compressed if you shoot it at 23.98 instead of 29.97.
24fps in the analog (film) or digital world is a form of compression (compared to 30fps) that seems to not only be ignored, but often touted as being better quality.Scott Sheriff

Since we are on the topic of compression.
You should check out (if you haven’t yet) this thread:
“Uncompressed and pixel resolution.”
Which is just a couple of threads down from this one. It has an interesting discussion on the blurry line of what is or isn’t compressed.Scott Sheriff

Everyone refers to 4:2:2 as uncompressed, but is it really?
If you only sample chroma at half the luminance resolution, which is what 4:2:2 is, then that is a form of compression. Just one that discards information that is not perceptible to the human eye, and takes place in a different place than traditional compression. But in a technical sense, half of the available chroma information is simply not recorded
So if you scan a frame using 4:4:4 color space, and then rescan it at 4:2:2, is there not a reduction of the files size? How do you account for that if there isn’t compression?
4:2:2 is called chroma sub-sampling, does that not imply some form of compression?
It seems to me that 4:4:4 color space is the only true uncompressed sample rate.Scott Sheriff

Perhaps the head clog happened during the recording. If that is the case, cleaning the heads now won’t help.
New tapes doesn’t automatically mean they are good. How they are stored, handled and used can effect performance. HDV is a fragile format that has to be treated with kid gloves.
I’m assuming you can see playback somewhere (cam? FCP? deck?).
What have you tried to resolve this besides cleaning the heads?Scott Sheriff

The search tool is a great forum feature.
You could use it to find the million other times these common questions (and others) have been asked.By the way, no need to worry about uncompressed HD. The 5D output is compressed, and so is the Convergent Design nanoFlash HD/SD Recorder/Player. 4:2:2 color space = compression.

Page 315 of the FCP manual lists the file types that can be imported. This is not one of them, so you need to convert these to a FCP friendly format.
On the up-side, since this isn’t your fault it is just more time you can bill for.

You might want to look at the ‘earthquake’ filter in FCP.
You might be able to tweak that to look like HH.Scott Sheriff

I like what Chris says.
But if adding in post won’t cut it, why shoot at a real motel? Unless there is something unique about the room, I think building a set is a better idea then shooting at the real thing. Most hotel rooms could be replicated pretty easy.
If shooting at this location is a must, what about covering the detector with a tupperware or similar container gaffed in place? Maybe plastic as a first layer for added protection. Depending on how much fog you do, you might want to cover the detectors in adjacent rooms, or at least open the windows.Scott Sheriff

Search the forum. This has been well covered.
