Keeping original frame size

zamar18 wrote on 6/11/2018, 11:12 PM

I'm new to Vegas Pro. I've a project encompassing 10-15 clips, and would prefer to keep some clips at their original frame size, such as 1280x720, 720x480, 640x480. Is it possible at all, and how exactly? If not, what optimal project frame size for that combo would you suggest?

If a project must be rendered in one common frame size set in Project Properties, what is the purpose to have similar frame size option in a Renderer? Can they differ, and in what scenarios?

Also, what does the option "Allow source to adjust frame size" do? Pls explain in detail rather then saying "it does what it says" because it doesn't, at least in my tests when rendering together varying frame size clips.

Similarly, what does the Renderer option "Allow source to adjust frame rate" exactly do in joining clips with varying frame rates?

For learning the most basic navigation and editing functions, you have been provided with a wealth of information and resources, both in Vegas and online. Please begin there, thanks.

Your exported (rendered) video can only have one frame rate and one frame size. Whilst your source files may be a mixture your output cannot. The purpose of several frame size options in the Render templates is to enable you to select the size you want, and likewise the frame rate.

The two render template options to "Allow source to adjust..." are meaningless when your source is a mixture of sizes and frame rates, as after all which one is Vegas supposed to use?. If you search the forum for similar questions you will find experienced users recommend leaving both these boxes unticked so as to avoid problems. It leaves you in control. With your "combo" I'd go for 1280x720 but you don't say what frame rates your clips have so cannot comment on that.

And since Eric understood your question, the exception is that you "can" mix frame sizes on a DVD title, but only from different source files.

Thank you guys.

Can I choose a different frame width and height in Rendering Settings compare to Project Properties, and in what scenarios? If not, what's the purpose to offer frame size options in Rendering Settings, if its already set in Project Properties?

@EricLNZ

Bigger frame size clips were taken by a smartphone at around 25-30fps frame rate, which slightly varies by clip, and chosen by the smartphone cam software automatically at taking the clip. Clips with 640x480 frame were taken by a USB cam with monitoring software at around 30fps variable frame rate. If I choose the project size 1280x720, the USB cam clips look too small on screen compare to smartphone clips after rendering as a project. Can I zoom the smaller USB frames somehow to look them bigger in the project render?

Any other ideas for the final project to look more uniform in clip frame sizes on screen? I tried the Project Settings option "Adjust source media to better match project or render settings", but it seems to degrade final video quality in some clips compare to original. What this option does, and in what scenarios it's useful?

Yes you can have different settings in your render choice to that of your project properties. Your project properties can also be altered at any time (at least in MS15 which I use, I assume Pro is the same) unlike some other editors which lock you in to your original project settings. But this can cause problems if for example you change from a 4:3 setting to 16:9 as you will get black letterboxing/pillarboxing due to the different aspect ratios.

Smartphones often use a variable framerate which can cause problems for Vegas, and other editors. Some recommend converting them to a fixed framerate with Handbrake before using in Vegas. But if the framerate doesn't vary greatly you may find Vegas is okay with them. I'd use a project and render framerate of 30 fps.

You can zoom any clip (called Events in Vegas) with its Pan/Crop facility.

"Adjust source media to better match project...." crops clips to better match the project aspect ratio. For example if you drag a 4:3 image into a 16:9 project it will crop it to fill the screen. You can "undo" any such crops using the Events Pan/Crop facility if you so desire.
