Editing 100MB video file turns into 1.5GB file!! How to control size??

No except upgrading to the Platinum version where you are able to customize the different templates after the "advanced render" option of "Make Movie" ,look here

Which option did you use to Make Movie or did you proceed to Advanced options? (Ignore the file details in the screenshot.)

JV, I don't have that Customize Template button. So this Vegas BASIC intentionally generates the largest possible file size? That's kinda BS. Think I should move to DaVinci? I only have the most basic editing needs (clip down a video)

vkmast, I pick MP4 in that intro dialog. There is no control over bitrate under advanced. All options under Sony AVC/MVC generate 3GB files for this 100MB source file. I think it all has to do with massive bitrate default.

No to the one that gives under all circomstancies the best renderresult. I think in this case it is better to use the Platnum version.
And switching to DaVinci is your decision.

Is DaVinci basically the same thing? All I need to do is 1) crop/rotate 2) delete clips 3) render

I have upgraded to Vegas 16 Platinum.

What setting should I choose for render?

Try one of these 3 templates

and customize to these settings

Maybe it could be better to change the bitrate by double the values for a better picture of the movie.

I don't even know what it is.

I do know that it affects file size.

I tested different bitrates with sample video of me fixing a laptop.

129,000 kbps = good
10,000 kbps = good
4,000 kbps = good
2,000 kbps = just starting to pixelize
300 kbps = full pixelized

Note: 10,000,000 in Vegas = 10,000 kbps in Properties

Does this depend on the machine viewing the video?

What situations require different bitrates? When would you ever choose 300? Does it depend on what is in the video? Static interview vs. panning movement?

I just looked at the bitrate of my source video file from my phone. It has 16,000 kbps. So, my rendered video probably should not be higher than that! But, it looks like I can go down to 4,000 and potentially make it 25% of the size.

No, it depends on source complexity. Less complexity needs fewer bits. More motion complexity requires more bits.

Can you clarify "complexity" ? What is simple? What is complex? Movement mainly? (Zoom whiteboard has no movement. Sports cam has large movement). What is movement ? Panning of the camera?

Musicvid wrote on 4/20/2020, 8:51 PM

Video complexity is defined as detail in motion.

Movement is motion. Any movement. Zoom is very complex if everyone is moving!

Looney Tunes is simple. Bladerunner is complex.

A still shot of a pond is simple. A video of rolling waves is complex.

A chess match is simple. An NBA game is complex.

More changing pixels = more bits = higher bitrate.

Bitrate is usually expressed as Megabits per second.

Besides resolution and complexity, one other aspect about needed bitrates is, the framerate. How larger the framerate the higher the bitrate needed. For example 50/60 fps need 1.5 times more bitrate than 25/30 fps.
