Rendering 1440 x 1080 to blu ray

[John Rofrano]

[Michael Denford] “I have 1440x1080i footage that I’d like to Render into a blu ray movie. What would be the best settings to use?”

I would render in the same format as the footage. If it’s HDV MPEG2 use MainConcept MPEG-2. If it’s AVCHD use Sony AVC or MainConcept AVC depending on your version of Vegas Pro.

[Michael Denford] “Would rendering into 1920×1080 make it look any better?”

No. If it’s 1440×1080 then render it as the same.

Thanks again for the prompt reply and advice John.

I am using Vegas Pro 11.

Is there any value in modifying any settings (i.e. Changing Video Quality to High, and Video Rendering Quality to High)?

As the files are M2TS, I take it i’d need to use the MainConcept MPEG-2 setting. Will the 25mbps setting give me a better outcome vs. the 8mbps setting?

I can imagine how trivial these questions sound. I really appreciate your advice.

Hi John,

The footage i am editing is as follows:

Type: MPEG-2 Transport Stream
VIdeo Stream: 25.000 fps interlaced, 1440x1080x12, AVC

Based on the above, it would be better to use the Blu-ray 1440×1080-50i, 25 Mbps video stream? I had a play with the Sony AVC templates and couldn’t find much difference between them (other than the output file size). Futhermore, the MainConcept MPEG2 HDV template required recompressing in DVDA.

Where applicable, i made changes to the templates to increase Video Quality and Video Rendering Quality to Max setting.

Is there any benefit in rendering as Progressive (from the Interlaced Footage)?

I am not sure if DVDA questions are to be submitted in another forum, but thought I’d ask here also…

What is the best DVDA Project setting to make a fully compliant Bluray Video Disc? – AVC vs MPEG2? (will obviously relate to the render in Vegas Pro). And what is the best bit rate settings?

Sorry to be a pain John….

Yes, since your footage is HDV MPEG-2 I would render to MPEG-2 using the Blu-ray 1440×1080-50i, 25 Mbps video stream template.

[Michael Denford] “Where applicable, i made changes to the templates to increase Video Quality and Video Rendering Quality to Max setting.”

That’s fine as long as it’s needed. Otherwise you will be wasting your time rendering and get no additional quality. That’s up to you.

[Michael Denford] “Is there any benefit in rendering as Progressive (from the Interlaced Footage)?”

Nope. Your TV is interlaced, you footage is interlaced, why would you want an additional conversion to progressive?

[Michael Denford] “I am not sure if DVDA questions are to be submitted in another forum, but thought I’d ask here also…”

I don’t think we have a DVD Architect forum so you’re in the right place.

[Michael Denford] “What is the best DVDA Project setting to make a fully compliant Bluray Video Disc? – AVC vs MPEG2? (will obviously relate to the render in Vegas Pro). And what is the best bit rate settings?”

I would use the Blu-ray Disc MPEG-2 1440×1080-50i 16:9 project setting in DVD Architect. Render all of your footage at MPEG-2 25Mbps. This will keep everything in the same format.

[Michael Denford] “Sorry to be a pain John….”

No trouble at all… asking questions is how we learn. (ask now or regret later I always say)

Thankyou for this very helpful advice.

I had forgotten to mention that the blu ray disc will be shown on a Full HD LCD (with progressive scan). Would a Progressive scan conversion make the video look any better?

I understand what you mean about unnecessary rendering. Based on your experience, does setting video and render settings to max (from default setting) make a noticeable difference?

If the video was not shot with a progressive camera then I would not convert it. Converting it will make the picture softer if you use Blend Fields and it will loose vertical resolution of you use Interpolate Fields so either way it will look worse.

[Michael Denford] “I understand what you mean about unnecessary rendering. Based on your experience, does setting video and render settings to max (from default setting) make a noticeable difference?”

I guess it depends on the footage. Render a small section of your video at the default and full and drop them on a BD-R disc and see if you can tell the different. I just did a test render using the default and max setting and the max setting took 8.5% longer to render. That’s not a bad trade-off at all so I don’t see much harm in maxing the quality out. I usually render with the default settings and have no quality issues.

Are you using DVD architect? The version I have only renders a resolution of 720×480…not 1920×1080

[Jeff Sims]

Which entropy coding should I use, and profile?

[Jeff Sims] “Are you using DVD architect? The version I have only renders a resolution of 720×480…not 1920×1080”

Yes, I’m using DVD Architect Pro 6.0. What version are you using?
