John,

One additional point to my previous post.

When I playback the rendered 1920X1080-60P video on my computer after being rendered in Vegas; the video is fantastic. DVDA insists on recompressing the video when rendering. I believe this is where the problem lies.

John,

Let’s start again. I think there is confusion on both sides.

My original clips are in XDCAM-EX filmed at 720/60P, 35Mbps.
I render in Vedas Pro 10 saving as a type MainConcept MPEG-2 file.
I use a Blu-ray 1440X1080-24P template and modify it for 1280X720-60P, 25Mbps.

I drop file into DVDA and change the default bit rate from 18 to 25Mbps. The video is again compressed when rendered.

The video playback is bad on my desktop player.

Take 2

Render 1440×1080-24p modified to 60P 25Mbps

Dropped in DVDA with sane parameters and 25Mbps

Again poor playback in player.

Take 3

Render 1920X 1080-24P modified to 60P

Dropped in DVDA with same parameters and 25Mbps

Still bad playback.

Any Ideas?

John,

The XDCAM video looks great on may computer after rendering in the Blu-ray format at 1440 X 1080 resolution, 60fps, and 25Mbps. The video degrades somewhat when rendered at 30fps. When the clip is dropped into DVDA and the same parameters are set; other than the fps which is maxed at 24, the disc playback quality is very bad. I believe this is a result of the clip being recompressed to accomodate the 24 fps rate.

Any ideas or suggestions?

Thanks

John,

This is my procedure.

1) Edit MP4 clips on vegas timeline, save and render in Main Concept (Blu-ray template 1440 x 1080 24P, 25 Mbps) and customize frame rate to 60P. (My original frame rate)

2) Insert rendered video in DVDA where it is further compressed.
optimized at 1280 x 720 resolution, 59.94 fps, 18.0 bit rate.

Please post a solution to this problem if one becomes available. I am in the same situation with the exact specifications.

[Bill Shepherd]

My thoughts exactly. There should be no problem. The audio is stereo not four channel. Could the problem be that Sony renders the PCM like AC-3 with a studio codec?

[Bill Shepherd]

The video plays great. The audio does not play.

[Bill Shepherd]

The unused speakers were correctly turned off.

Since the video and audio are correct after rendering on the Vegas Timeline, I am going to try burning to a BluRay disc directly off the Timeline and loading the BluRay onto another computer to see what happens.

I have a feeling the player I am currently using may be the problem.

John,

LF,RF,LR,RR and Center speakers still activate after rendering with the new mappng. The preview before rendering works perfectly.

[Bill Shepherd]

John,

There is no contol over the speakers. I can edit four seperate audio channels and they work great in preview. However, for example, if the front right speaker is edited to be the only channel emitting sound, sound comes out of all the speakers after rendering.

I realize this is noncompressive rendering. I am sure I am wrong, but I would think noncompression renedering would be easier to accomodate multichannels.

Would Vegas 10 or some other program accomodate multichannel audio in a XDCAM EX formate?
