Clean rendering from 4K video

kentiler wrote on 5/25/2016, 10:23 PM

I have 4K video that is in .MOV format. I edited it with Vegas Pro 12, and chose to match the original video's settings for the project.

I've tried to render the edited video as Blu-Ray 1920x1080-60i and several other hi definition formats, but the clarity of the final project is terrible when compared to the source video.

What format would be best to render to for video including audio?

What does Mediainfo say about your source? Post the tree view.

If you are going from 4k to 2k then of course it will not look as good.

How are you going to watch the finished product?

I searched through the Vegas help and can't find anything about MediaInfo.

When I right click on the media under Project Media, I get this info:

By MediaInfo, I'm pretty sure he meant this.

The issue is not the source footage - but the capability of Vegas to downsize the footage from UHD to HD. Good methods to do would be Lanczos 3, but that is not available in Vegas. People tend to use other Tools for that step - I use TMPGenc but there is also the free tool Handbrake.

Why do you output in 60 Fps when the source is 30 ?

Why do you output interlaced when the source is progressive ?

Have you set "Disable resample" for all input media ?

I frequently render GH4 UHD footage to HD and it looks identical to the original when played back on either an HD computer display or a 4k TV.

I typically render to AVCHD files at 28mbps, 1080P, 29.97 or 23.968.

Perhaps you could try a small section this way to see if the problem lies with your 60i blu-ray settings or elsewhere.

Make sure you render at "Best" instead of just "Good" if you haven't already since you are resizing the video from 4K to HD.

ritsmer - I guess I wasn't paying attention!

Kinvermark - I'll try those suggestions.
