So this is my first time editing a video that is intended only for mobile. I’ll include a photo of my project settings below. I’m wondering if anyone can suggest a render format that is best. I’m working in Sony Vegas Pro 14.0. Thanks!

There is no right answer to your question. “Mobile” has changed so much over the years in both the ability for people to download at high speed and the also the screen resolution and computing power of mobile devices.
I originally, encoded videos with a specification that would make them play well even with very low powered smart phones. “Back in the day”, I picked 512×288 pixel, h264, 25fps in an mp4 container. Surprisingly this still stands the test of time in that the video files are very compact, file sizes are very small, allowing my clients to have hour long videos on their phones.
Today, the processors in mobile devices are very powerful, internal memory is enormous and the screen resolution is exceptional. In effect, most mobile devices can play HD or 4K video better than their desktop counterparts.
So technically, you have to know your lowest common denominator, in your target audience (clients). And ask the following questions:
1. Is the video going to be streamed in real-time to their device?
2. What is the maximum bitrate that will play back smoothly on the processors in the mobile devices for your content?
3. What file size do you consider acceptable for your video, if you want your clients to store the movies on their device?
4. How much movement is in the video content. Fast action movies require higher bitrates for smooth stutter-free video.
Once you have these parameters figured out, you can set a pixel size, bitrate, fps combination that meets your criteria.
I am currently delivering mobile content in HD, 25fps (Australia), 5Mbps and have very happy clients.
Incidentally, there are many online calculators that will give the relationship between the parameters I have described. You don’t even have to know any maths!
