I know this has been asked to death, but another Project Settings/Render As Settings question
I shoot AVCHD at 1920x1080p, 24p. I was doing a “talking head” small project, and the final render was going to be 600×338 (I calculated that that would still be in a 16:9 aspect ratio).
I set my Project Properties to match the aspect of the original shot video (1920×1080), but then in the Render As dialog box, I set the final size to 600×338.
When I did that, the sound sync would end up being off slightly.
So, I set the Project Properties to 600×338, kept the Render As as 600×338, and the final videos came out okay.
But in reading some previous posts here, it doesn’t sound like I should have done that. Most posts suggest setting Project Properties to match the original/source footage.
What should you do in a situation where your final render as size (or other settings of the final render) is going to be different than the original footage size?
Or, an idea just came to mind: is it recommended that I set Project Properties to match source footage (in this case 1920x1080p), then keep those settings in the Render As dialog (1920×1080), and then use a post-render program (I use a freebie called MPEG Streamclip) to compress it (for the web) and at the same time change its size to 600×338? (Just an idea.)

600×338? Maybe this is the reason?
I would use 640×360 (youtube compatible 16:9 SD format)I prefer to set the project properties to match the render format (not the source). Thus, I have full control of what I get at the output. Ideally, if the output is the same as the source.

If the final render is the same aspect ratio as the source footage, I would set your project to match the source footage.
If the final render is a different aspect ratio than the source footage, I would set your project to match the final render.
The problem that you have is that 600×338 is not 16:9. 600 cannot be divided by 16 evenly. (600 / 16 = 37.5) and 338 is not a multiple of 37.5 (37.5 x 9 = 337.5). Video frame dimensions are measured in pixels. There is no such thing as a fraction of a pixel. When you calculate frame sizes, you can’t round up or down and have the same aspect ratio; you need to be dead-on.
Try keeping your project as 1920×1080 and render to 640×360 (both 16:9) and you should be fine.

Thanks. It’s clear now.
One problem I’m having though, is that my source is 1920×1080. I want my final render to be 640×360. The text in my final render ends up a bit with jagged edges when I shrink it down.
Any way to get sharp text when going from 1920×1080 to 640×360?

Jaggies occur when rendering higher than your project, not going down in render size. Are you sure you’re evaluating a final render and not a preview? Else, check your quality settings when you render?

I found that strange, too. I know in Photoshop when you upsize, it can cause jaggies.
I’m definitely downsizing. Going from 1920×1080 to 640×360.

That did it!
I just needed to set the Quality to Best in the Project Properties!
Thanks.

Great recovery!

Yea this is something that most people overlook. When rendering to the same resolution you can use the default rendering quality of Good but if you are resizing your render, you should use Best because it uses bi-cubic resizing. Glad you got it working.

“bi-cubic resizing” Oooo John, I love it when you talk tech. 🙂

Yea, well… all you need to remember is that the difference is that Vegas uses a different resize algorithm between Good and Best so if you are resizing, always use Best.
