Solved Vegas Pro rendering for cinema size screen -top level video AND audio

I'm new to Vegas. I'm using it to prepare a video/audio file which will be shown on a large/huge screen at a Conference event - the quality of AUDIO is as important, if not MORE important that the picture/image quality.

Given the size of the potential screen, can anyone advise the best "Project Properties" and "Render As" settings I can use.

Audio is 48000Hz, 24 bit. The video is 1920x1080 with a frame rate of 25.000 (PAL).

I did one text already, and the result was not so great. I rendered using Sony XAVC Intra 1920x1080 -25p. The resulting file was a .MXF file. This opened on my PC using VLC Media Player. The video picture looked OK, but the audio was terrible.

Thanks for any advice.

Hi Mosaic

Where did the Source Video for this project come from ?
What was the original Bit Rate for Video ?
What was the original Bit Rate for Audio ?

Unless the source video came from a professional grade, high bit rate recording, I would recommend sticking with regular Mainconcept AVC/ACC and use the Internet 1080p template. Using this format and template, you can set your Video Bit Rate and Audio Bit Rate.

It makes sense to use the same or very similar bit rates to what the original video was recorded in.
Some people think that rendering to much high bit rates than the original will increase the quality, but it will not.

I would also recommend using the same Bit Depth (16 Bit or 24 Bit) as the original - increasing this more than the original, also is not a good idea.

A have a tutorial for rendering 1080p 50fps/60fps video you can read/watch here.
Obviously you will be using 25 fps settings and not 50 fps settings, but everything else will be the same.

If you don't know the original details for your source video, you can find out what they are by using this tool here:

Thanks for the reply Derek. I used the link you gave and the detail on the video is this : its supposed to be used on a big screen - does it look good enough from these stats? Bit depth is 8 bits -- is that not good?

There Audio profile is missing from the readout you copied - only Video data is showing.

8 Mbps is a fairly low Bit Rate for an original video.
8 Bit Colour Depth is standard for everyday video.

My guess is that your original Audio component would be 48,000 Hz and 16 Bits (Bit Depth).
If this is the case, you should keep the Audio Bit Depth the same in your Project Properties and Render Settings.

As I suspected, rendering to Sony XAVC is overkill.
Sony XAVC encodes at 50 Mbps for 1080p video.

If you render to the standard Mainconcept AVC/AAC - Internet 1080p template, your video should turn out as good as the original video.
Just make sure to set the Frame Rate to 25 fps.
I would guess your Audio will be 192,000 kbps or slightly higher.
