Marco from OneRiverMedia even tells a poster that it’s 4:2:2 until 100%.

What does it make it *at* 75% then? 🙂
Photo JPEG is RGB-only at 100%, and I don’t think you’re right about the 76-100%. There’s a lot of conflicting
information on the web about it. Do a test. Take a 10 second video clip and export it at best (100%), high (75%)
and then export one at just a touch below 100%, as little as you can move the slider. The 75% file will be significantly smaller
than the 100%, of course, but so will the “almost” 100% clip. My clips were 32MB, 48MB, and 117MB. The clip at (approximately)
97-99% is less than half the 100% size. 4:2:2 at 99% or less? I think so.
A lot of the “75% setting” opinions talk more about how you’re not gaining much quality by going higher, not whether it switches to 4:4:4
mode that low.
Ed[Charles Simonson] “Ed, Photo-JPEG can handle both RGB and YUV at various color sampling modes. At 76 – 100%, P-JPEG is 4:4:4, and below 75%, it is 4:2:2.
Here is a great resource for learning about editing codecs that I have referenced for a long time now:

Don’t put all those wasted pixels in the timeline. You’re relying on FCP to scale it
when you should do it in Photoshop first. If you’re not using the DV video preset in
PS, which will do the square to rectangular pixel thing for you, size your graphic at 720×540
(square pixels) to have it look right in rectangular video pixel land. Add a little vertical motion blur
while you’re in PS too.

Yeah, c’mon, it isn’t brain surgery! Sorry, I’ve never had a chance to say that
to someone around brain surgeons before. 🙂
How about the Sheer Video codec for archiving too? And doesn’t saving as
PhotoJPEG convert the YUV video into RGB? Not sure of that, but I think so.
Then there’s the dreaded random QT gamma change when playing PhotoJPEG.

Do a search of the posts. Your question has been asked, and answered soooooo
many times. If you did them in Photoshop, add Motion Blur (vertical-only) in PS, set it at 1 or 2,
that should be enough. Follow the previous advice for crawls.

Delete everything South of the Crown Point bridge. You won’t have a problem and the rest of the
lake will thank you. 🙂

More info! I use my PB to capture video occasionally and it works fine.
More details, more details!

What version of Compressor are you using? If you’re using Compressor 2, under Settings, there’s a Web Download
option for Quicktime 7 compatible (H.264). Set a bit rate and you’re off!

I don’t use Premiere so I’m guessing, but what are your de-interlacing options?
DV is Lower Field for setting de-interlacing. Are you given an option of Upper or Lower?
If so, choose lower. You also might ask for specifics in the Premiere forum.

What’s your compression workflow? If the jaggies appear on the “actual source”, it’s probably interlaced, and that’s normal
when viewed on a computer monitor.
How are you de-interlacing? And what are you viewing it on? Details, details! 🙂
