No Recompression Required On XAVC?

Today we rendered a veg file from Vegas 13 to an XAVC intra file from someone else's system, then I brought that into Vegas 15 on mine to make some more edits on it. It wasn't practical for me to use a veg file because the source files were a mess on different drives. After I made my edits, I re-rendered the AVC file and was interested to see a message appear on monitor : No Recompression Required. I have never seen this message before. During playback while rendering sometimes the message would appear, and then it would disappear. Is this something new to Vegas 15 or does XAVC not recompress itself in general no matter which version you are using. I have been using Vegas since Version 9 and have never seen this before. Just curious.

Smart Render is precisely why so many people use it for intermediates. Of course cuts will be rendered to reinstate GOP integrity. You can't start a new scene without an I-frame.

Try this forum's handy Search feature(!), match you render to source, and proceed.

Smart rendering has been around probably since Vegas started supporting video. As soon as you edit your video in any way, such as adjusting pan/crop or an FX, no format will smart render.

Search "smart rendering" in the Vegas Help. Details of supported formats are in there.

AVC from any source won't smart render in Vegas, it's the gop.

I like VideoRedo for this.
