Strange black gaps between shots in Vegas Pro 16

Hello.

I am having difficulties figuring out to solve an issue that is bothering me. Have not found any similar issue here on the forum or by searching.

I am working with a UHD 30fps footage from Panasonic GH4 and Olympus OM-D em1 mII. All source videos were converted to ProRes 422 before I started editing. It alone was an insane increase in observed editing speed. Like I had bought a new computer :)

I was almost done with my edit when I noticed in playback a very short "black gap" between all shots. If i place the playback marker right between the shots (as shown on picture) the preview screen shows just black video. If i go one frame backwards or forwards it shows the correct image again.

This is very noticable in final rendered video. This does not happen with ALL the cuts. It seems random.

When I zoom into the timeline I can actually see that Vegas had placed a short fade-in effect on the beginning of each shot. And that is causing the black gap. See next picture of the same part as above.

I initially thought that this was just a bug or something so I went through the whole video and removed the fade-in parts. Then it looked fine again.

Saved my work... and when I opened it again the day after it was back to this.

I really don't want to go through every cut and remove short auto generated fade-ins every time I load my project. Does anyone know what can be causing this and how to solve this?

And side question. What does it mean when fade-in handle is blue and when it is orange?

Did you have Quantize to Frames enabled? If not, this will cause this problem. You ALWAYS need quantize on when editing video.

To expand a bit, Quantize and Snapping must both be ON BEFORE adding any media in a NEW project. Media and project frame rate must match.

Closing the barn door after the horse has escaped does not work in this case.

Also zoom in to be sure your prores render did not add any frames.

And if not, Vegasaur has a tool for fix this. Project audit will find not-quantized events, and shows option to fix one-byone, or fix them all in one click.

Since you mention it, Vegasaur also has one click close the gaps which will get rid of the black spots. There's also scripts for that. But neither fix the annoying one frame random fade-ins, which I've also encountered (quantize and snapping on).

@Rainer - check in Preferences and there might be something you can alter. If not try the hidden Internal tab.

Thanks Eric, but nothing relevant there. It's random, .mov footage, can't reliably replicate it and for me rare enough not to worry about.

@Zkuggi

Did you check that the project- and media- frame rate match ?

You can set the internal preferences to indicate events that are not on frame border (unquantized)

BTW this function was added to Vp16. So you don't need Vegasaur nor a script with Vp16 for that.

Thank you all for excellent help with this.

Another example of editing with a Vegas Optimized format vs the camera original format. This is also info in the sticky at the top of the forum.

Could someone please tell me where this script is located that you say is now standard on Vegas Pro 16? I have a large number of gaps on the time line where when I have used the cut tools, it is randomly leaving a single frame gap. I can see no script listed to take the gaps out,

With me it is no script but an edit function.
First rightclick the first event and choose "Select Events to End", second go to the menu "Edit" and choose "Close Gaps"

Got it thanks J-V
