Appreciate there are a lot of free programs ... but as I have project in Movie Studio I have to render to something, so wondering if I can do this direct.
Rather than render as one format then a separate program and separate step.
The second step is a mux (that means multiplex), not a render. Couldn't take more than a minute or two to rewrap a compatible file.
You could "try" a render to .mts in Vegas, and change the extension to .ts when you're done. But of course I have no earthly clue if this will work for your purpose.
