You are talking about “extend a shot” and JPEGs, so not sue if you are editing stills or video.

[Edwin Street] ” file in Media Info it shows this:”
which “Media info’ are you talking about?To undesratnd Chroma Subsampling, please have a look to this article of G. Nattress:
https://www.nattress.com/Chroma_Investigation/chromasampling.htmIn short:
– 444 there is no subsampling; Each pixel has his own Y + Cb + Cr information.
– 422; Each pixels has his own Y information, but only one every two pixels has Cb and Cr information.
– 411/420; Each pixel has his y information, but only one every 4 pixels has Cb and Cr information.Chroma subsampling can only exist in YUV (YCrCb).
Chroma subsampling is not possible in RGB, because there are not chroma channels.rafael

Change the sequence codec for Prores and set “Render all YUV in High Precision”.
Render the sequence and then export with current settings.

Hi Ben,
I’m a PAL land guy, but after so many years reading almost every post in this forum, I think, I’ve got some understanding on managing NTSC-land time-bases.I think the easier, faster and the one workflow that would keep the best quality would be editing in 23.98fps and then convert in Compressor to 29,97fps.
Compressor would just add pull-down.To make the 23,98fps > 29,97fps in Compressor, fallow Jeremy’s advise in this post:
https://forums.creativecow.net/thread/8/1136496#1136510The point is that by using the FAST (Next Frame) option in Compressor, the picture is not re-copressed, and the interpolated frames are build not by repeating frames, but by putting together one field from each adjacent frame. That makes the picture look smoother.
You can deliver your 29,97fps master just like that, or if you have time and feel like doing a second edit, replace in the master the footage what originally was 29.97fps.
Not sure if is worth this extra step.

[Joseph Owens] “Your green bar might mean that you are carrying RGB in the 4:4:4 tables, which might give FCP some issues. Unfortunately there are no flags in the ProRes4444 codec to explicitly state what it is, exactly, that is being transported”
You are right Joseph.
We had this discussion long ago.
The problem is that there is no way to control which Prores444 flavor (RGB or YCbCr) we get on exporting.
I understood that applications that render in RGB (AE, SHAKE,..) export RGB and so applications rendering in YCrCb (FC) export YcrCb.
It seems that Compressor do it on RGB.

If your PANASONIC monitor is properly calibrated, that’s the only valid reference. Your movie will look OK in every properly calibrated monitor, and that is what will be required from your products when you will be working.
I work with three different monitors and in each of them my videos looks different. I fallow the only one I can be properly adjusted.
If you want your movies to look OK in every single monitor/TV, you will need to make too many version.

[david mayer] “How to compress final project for HD upload to YouTube
if not as a Quicktime movie?”
Yes, but there are many ways to make a QT Movie, and the final quality may depend on the workflow and the tools.
rafael -
Open and save your project with a different name and see if that helps.
rafael -
Change the sequence codec to Prores and render.
Avoid QT Conversion.
