You’re welcome, Silvy! Glad I helped!

“Ghosting” is exactly what you described with “warpy lines that make it look like you were shooting in a heat wave” and is caused by slow shutterspeeds.
A general rule of thumb in video is to use shutterspeeds about twice as high as the framerate your shooting. With 24 and 25 fps it’s a shutterspeed of 50, with 30 fps it’s 60 and so on…
If you’re going higher you risk strobing, if you’re going lower your risking ghosting——————————————

Glad to read your problem is solved!

[Adam Robert] “I can’t even view them in my computers video player, Windows media player”
That’s weird… Have you tried reinstalling the codec?

[Adam Robert] “but I can’t play the files once they are converted”
Premiere doesn’t recognize the files after conversion?
Maybe a stupid question, but do you work with the files on the same computer that you were using for transcoding?Once installed, DNxHD should be available in every software or player (except for example players like VLC, that bring their own codecs)…
I don’t think it has to do with MPEGStreamclip, but have you tried “5DtoRGB” (https://rarevision.com/5dtorgb/) for transcoding?

To add: noise can be tackled with various noise removing plugins, “ghosting” is something that you can’t remove successfully…

Well, I’d rather push ISO and do noise reduction in post than have to deal with “ghosting”. But that’s purely a matter of personal taste and/or your skills in post-production…

[Brandon Morris] “Is the t2i a better choice over the hpx170?”
From what I read, the HPX170 has an HD-SDI output with uncompressed HD at 10-bit and 4:2:2… If that’s true, the HPX170 is the way better choice for greenscreen work.
[Brandon Morris] “Should we transcode in FCP to ProRes 422 or 444?”
IMHO this doesn’t really matter. With a T2i you’re starting with 4:2:0 material and just “wrap” it in 4:2:2 or 4:4:4 – so no more information after transcoding.
[Brandon Morris] “Would using the technicolor cinestyle benefit anyway with keying?”
Anything that improves picture qualitity improves the keying process, but I can’t say anything about the Cinestyle and keying. If I have to do keying with Canon footage (which is not the best source footage hence the extreme compression), I’d rather choose the “Faithful” style since it is said to provide better color-information.
[Brandon Morris] “Are there any magic lantern features that benefit?”
Yes. The possibilities to shoot with multiples of ISO 160 that reduce noise drastically.
[Brandon Morris] “Is there any way to shoot in 444 color space with a t2i or hpx170?”
With the T2i: no. With the HPX170: I don’t think so…

[Daniel Hughes] “I don’t really want to shoot in full HD and crop because then I’m losing the top and bottom of the image and a lot of visual drama.”
You’re losing space left and right of the footage, aren’t you? Or did I misunderstand your quote?
I can’t imagine a technical solution, but are you using Magic Lantern with your T2i?
If so, you can use a custom 4:3 cropmark, that can help with framing the shot.
Or you could use some transparancy tape with hand-drawn cropmarks and stick it on your camera…Just my two cents…

Very informative! Thanks for sharing, Thomas!
