Need Clarification on AVCHD render quality

[Tero Ahlfors]

When you render previews you are always replacing the old render with a new one. Generation loss will not come into play because you’re not re-rendering the rendered preview..

But let’s say I render a clip then add a new effect and render again. Won’t that be a generation loss or am I confused.

If you actually export a clip out of the program as a new clip and bring it back in and then put more stuff on it then it will start suffering from generation loss.

I’m not talking about exporting. I’m talking about rendering. The yellow bar or red bar rendering into a green bar.

Hi Bryce,

I responded to your post on another forum, but did not directly address the root of your question apparently.

If you render a red portion of timeline to green, then make any edits that cause that segment to go red again, you are back to square one – each time you render red to green is like the first time, it always renders directly from the source clip to preview file format. It does not use the previous preview render file, that gets completely replaced.

Please see this Adobe post for additional info on colors – https://blogs.adobe.com/creativecloud/red-yellow-and-green-render-bars/

Thanks

I thought that was the case. I was confused why I got different reply above from someone else’s.

Bryce,

I should add that Tero’s replies are totally correct, but maybe were not interpreted properly when you read them.

Thanks

But when I render a yellow bar to green I don’t see any quality difference. The rendered previews are in prores HQ. do I need to transcode to pro res or can I just use native avchd and call it good?

Bryce

[Chris Borjis]

you don’t need to transcode.

I do commercial production and been exclusively on premiere since CS 5.5

I have not transcoded a single piece of footage since switching to premiere and one of our sony cameras
records AVCHD.

What about color correcting? Can I color correct in avchd? I read that the colors can get washed out unless you render and replace with something else.
