Thanks for your reply:)

I think I must start from the beginning!
File / New / 4K 16:9 24p (4096x2304; 23,976 fps)
I have chosen "AVC MP4 template,"
This is the only "4096 x 2304" that I see in V10 or V11
but could not succeed in customize it as 3840x2160

Upgrade to Vegas Pro 13.

Vegas 11 appears to have a 2048x2048 limitation for all the render templates I've tried.

It's like Hotel California:

"You can check out any time you want, but you can never leave."

You can type in anything you want but you're going to get 2048x2048.

Try this file rendered from Vegas Pro 12.

:) Yeah Hotel California has always been an unchallenged song to me until that age.. 60...

I watched your video.It's nice. The question is my Vaio's screen resolution is 1920 x 1080 so...

I downloaded V13. Trial version. By the way should I wait for V14?

In V13 I could only find "3840 x 2160" at "XAVC INTRA" but I think it is not very widely supported format and I should convert it ?

Thanks again.

"[I]...should I wait for V14?[/I]"

I wouldn't.

You should use your Vegas 13 trial period to look at all the possible render options that your TV will play since you're only going to buy one TV for now. Different manufacturers differ on support of the UHD video formats.

Don't worry about your editing monitor not being 4K for now.

You should also try the Vegas2Handbrake workflow.

>> By the way should I wait for V14?

Not unless you are immortal. It's never coming.

Add, just experiment with 4K first time, as DJI Osmo finally arrived and had a first time testing :D

But I must do a CPU rendering only as GPU is not sufficient any further (makes a lot of artifact on render result). Do very short duration test before proceed a full-length rendering.


Set

Thank you "set"!
Handbrake gave me the opportunity to render it as mp4 or mkv but I can't play with the bitrates too much??

By the way is there any web site that I can upload 4k video?
