Quote: Hello once again,

I have 100's of films that I have scanned and put in position for editing.

My question is: during editing I usually add the music and do one render for the whole edit process for each film.

If I do the editing without adding the music then come back and add the music and do a second rendering do I lose quality and file size by the second rendering?

I would do normal editing for all the films then come back and do all the music additions and render/multiplex the music into the videos then move on the create disk.

If you can use SVRT in Produce with your edited videos, when you add the music, only the music will be rendered.

With one of your produced videos on the timeline SVRT information is View > SVRT Information (ALT+S).

Green means no rendering needed.

SVRT is very dependent on the video profile used to produce the edited video.

Using Xavcs and with a video file and audio file on the timeline the SVRT is grayed out and not usable. It also seems to be grayed out with different rendering options.

That is correct. SVRT only works on some profiles.
AVC and MP4 usually works.

I do not know if SVRT works for 4K material.

Tried it with a file created by XAVCS - the file created was a .MP4 file.

It had an audio stream on the audio track.

I may just have to add the music during the first edit prior to PRODUCE. Prior to rendering/multiplexing the file out for creation.

I think I am zoning in on it using the manual.

The manual does not discuss the XAVCS format which seems to be not much different then the .264 format. They both produce .MP4 rendered files. (XAVCS is supposed to be a little better from what I understand)

If the SVRT line on the timeline is green it does not need to be re-rendered. If is red it does have to be re-rendered.

Not clear on adding a music track in a rendered file. It would seem it would have to be multiplexed into the video stream which means re-rendering. But what do I know.

Tried taking a rendered video file only, then set the SVRT then added music, the green line still showed you do not need to re-render the file. I imagine you still have to produce it out to get the music added it just may not re-render the video.

Not sure.
