Rendering till blu ray

[John_Ro]

Hello to all who read this message.

I found this website in my search to answers for an few problems i have, so i am a kind of new here. I try to figure out how this new time age of video is functioning, because i came from the 16 mm and Betacam SP time age 25 years ago, and recently i picked up in the digital time age.

For recording i used an Nikon D5100 camera, all went great, and i edit it in sony vegas, maybe not the best editing program when you have a documentary from 1 hour? Anyway, i managed to make a docu, with many stuffs in it with different formats. Anyway, after i have rendered it in 1080p internet format it looked very nice, but when i rendered it in .m2ts format to put it on blue ray with multiAVCHD the result was a disaster on Blu ray disk.
There was on both sides cut away a lot of the screen like i went from 1920 to 1440, the picture looked horrible like there was a to harsh sharpness, the picture went at least 3 f stops darker, so the blue color disappeared in a black background with a flying head as result. And the audio sounded like a tin can while recorded on PCM.
With other words, from the whole quality from the camera and audio recording was nothing left. While it looked so great on the PC.

So now i would like to have an advice how i must render or setup vegas and multiAVCHD to get the best quality in audio and video on an blu ray disk.

Here Is the specs from the camera recording:

And if possible explain why so i can understand because there is a lot changed in time and i need to catch up

i managed to make a docu, with many stuffs in it with different formats.

Many formats? What dos that mean? You can have only one frame size\frame rate\scan type\codec in a BluRay or AVCHD video.

after i have rendered it in 1080p internet format it looked very nice, but when i rendered it in .m2ts format to put it on blue ray with multiAVCHD the result was a disaster on Blu ray disk.

Rendering for the internet and encoding for BluRay BDAV are two different matters. The BluRay standard for 1920x1080 @25fps or 30fps requires interlaced video, not progressive. 1080p BluRay is valid only at film speeds 24fps or 23.97fps. Your original rendering was re-encoded for BluRay BDAV disc and interlaced, at a lower bitrate than your original. https://www.videohelp.com/hd#tech

According to media info your 1080p render uses a Rec601 color matrix (which is a standard definition matrix, not HD) and "BT.470 System M" color transfer is for the old MPEG1 standard, not for DVD or HD.

Hello, Lmotlow.

Thank you for leaving a reply.

"Many formats? What dos that mean?"

I mean that in the documentary there are also pictures and parts of movies with an other size.

"According to media info your 1080p render uses a Rec601 color matrix (which is a standard definition matrix, not HD) and "BT.470 System M" color transfer is for the old MPEG1 standard, not for DVD or HD."

So what should i use then in sony vegas to render?

[John_Ro]

PS

I tried rendering with BT709 but then vegas is crashing because of low on memory, while i have 4Gig on the mainboard and a 1Gig gtx470 videocard. I set vegas to render with GPU. Is that not enough or am i doing something wrong?

[poisondeathray]

Try disabling GPU render , it's known to cause some problems in vegas


The levels issues sound like studio RGB vs. computer RGB issues. These issues are common in Vegas and require some workarounds depending on how the project is set up. But I cannot explain the AR issue

Any reason why you aren't using Sony DVDA for the authoring ?

[John_Ro]

Thank you for replying,

I don't have Sony DVDA.

Should BT709 with normal cpu rendering solve it you think?

[poisondeathray]

DVDA comes with Sony Vegas

It's absolutely not a BT 709 vs. 601 issue. This will only shift the colors slightly. This will not explain the levels issue or AR issues or audio issues

Crashes and encoding defects do occasionally occur with GPU rendering activated . These are known issues if you visit various forums like the Sony Vegas forum, or CreativeCow.net . Whenever something buggy occurs, the 1st advice is always disable GPU render

[John_Ro]

Then i must look on the rom if there is dvda.

So then i must search for the RGB settings?

[poisondeathray]

You can also download DVDA from the sony website.

First I would test your already rendered file and import it into DVDA

[John_Ro]

Ok, i will try that tomorrow, it is now a bit late here and i don't want an angry woman in the house

Thanks, i will let you know the results.

[poisondeathray]

hahaha can't have that now


There is a "preview" option in DVDA that simulates a disc playing with navigation commands etc... So check the levels, audio, and AR in the preview within the program first before you burn a "coaster"

[John_Ro]

Nop, it keeps crashing even when i turn my GPU off and let it render on cpu.

[poisondeathray]

But you were able to successfully render a "1080p internet version" without crashing ? Not sure what is going on

[John_Ro]

Yea, that is right.

It is strange indeed, but now i turned of the GPU and it rendered to 60% by now with the BT709 color matrix.

I guess that the GPU needs more then 4 Gb memory. I am also thinking about updating my PC a bit because i see many people with more then 16Gb working. So i am orientating a bit what to buy. But i am now fighting a bit with rendering because i made the whole docu in vegas, some interviews with more camera angles, and don't want to start all over again.

[poisondeathray]

If it was a system hardware issue (e.g. overheating, memory, stability etc...), it should have crashed when you rendered the internet version. Did you not use GPU render for that as well? You can try disabling GPU acceleration in the main settings as well (not just the render settings)

No, with the internet version it went normal, even with GPU acceleration.

I got a GTX470 video card with OC panel, but it is protected against overheating. It is just with some render settings that it is vegas is crashing.

But the system i got now is doing 3 days rendering for blu ray from a docu from 1 hour....that is not really productive so to say

I make voluntary educational docu's for schools here in Romania, so it is not really with deadlines but it is a long time waiting. With Betacam SP I would be done in a few hours.
