Vegas Render Issue

i c e wrote on 1/1/2015, 9:55 PM

Hello everyone,

I hope this new year brings you many new and great things! :)

I have been shooting this short/docu with my GH2 (that you all so wonderfully helped me decide on) and have been using the hack to shoot at 88mbps. It looks so fantastic it's amazing.

So now I near the completion of my project and have two questions. They are kind of separate but I'll use the post for both and kindly ask that you might use numbers for each topic to help me figure this out. Thanks a million for any help in advanced.

1. What is the absolute best render settings I can achieve for use on an Ipad/MP4 or MOV/Web

2. What are the absolute best render settings I can achieve for a DVD to be mass (small mass) distributed.

I feel like I am somehow getting jipped shooting at 88mbps and now have to go so far down on the final render. But I hope somehow it will all trickle down to look better in the end.

I am using the latest version of VP13. and architect Pro 6 for the DVD burning.

Again, thanks a million for any and all help.

Joshua

Nobody cares about quality on portable devices. If it has colour and movement, that is enough. :) (Sorry! I couldn't resist)

So far as DVD is concerned, render to a DVD template at up to 8 Mbps if it will fit and that is all you can do. The specs for DVD are quite specific and the only real option you have (other than NTSC or PAL) is bit rate. Two pass variable bit rate may squeeze a little more quality than fixed bit rate.

If you are starting with HD to make a DVD, then this topic has been covered ad nauseum. Your output should be SD 50i or 60i to comply with the DVD specs. If you are starting with interlaced, then make sure that you set the deinterlace method in your project properties to "interpolate", so that Vegas will resize each field separately.

Thanks Peter.

The reason they will be put on an iPad will be to project in HD on 5+ft screens. So quality will be of the upmost importance. It looks like I can get a 25 fps in Vegas. But I am wondering if it's possible to get more.

Then I will also put them on the web, where yeah, quality isn't really that necessary.

Thanks for the advice on the DVD renders. I will have to check my footage to see if it's 24i or p as it only shoots at 24 fps. ... I will also try to look up some of the older forms here.. though usually there is one or two factor that make their situation different than mine.

If I am only getting 8mbps on the DVD... is there any advantage in shooting at a massive 88mbps??

Thanks so much.

Anyone else?

You won't be able to get better quality than the video as you shot it. Any subsequent processing will degrade it to a small or greater degree.

"I will have to check my footage to see if it's 24i or p as it only shoots at 24 fps."

Your 24 fps will almost certainly be 24p (progressive). That will need to be converted to 50i or 60i to put on a DVD. For NTSC it is usual to use a procedure that repeats fields to get 60i. For PAL it is common to just re-speed it to 25p and render to 50i.

"If I am only getting 8mbps on the DVD... is there any advantage in shooting at a massive 88mbps??

If your end product is only DVD then "no!" If you intend to use higher resolution either now or later, then a higher bit rate is most desirable.

an IPad platform for quality play on video screen is an absolutely ridiculous idea. If you are shooting high quality HD then you need a Blu-ray disc output to video wall, or a portable harddrive, or a media player of some beef. NOT an Ipad!

Thanks Guys.

VideoITguy.

I agree completely, I said the exact same thing initially. Then someone talked me into trying and hooked it all up using hdmi out of the iPad mini and played a 5GB file and it looked really good. I am still doubtful, but am wondering if it MIGHT work.

But yeah, blue ray is the way to go. .

I am still curious in how to render out a higher bit rate in Vegas than 25.999 mbps that can be used in some way. Anyone know this?

thanx again

Your Blu-ray stream will be taken into authoring by DVDAPro. The best possible render quality with Mpeg2 format is going to average 26 with occasional peaks at 28 and valleys of 23. This is with the best possible source video and production values - your piece can even look better than commercial Blu-ray on a 52inch widescreen.

Stop fretting about bit-rate - it is all handled by the encoding, the player, and the large screen.

Thanks Guys.

That helps videoITguy. I guess I am also wondering in all this.. .going forward, should I keep filming in 88mbps? What for? I mean Maybe I should drop down to around 30mbps on my camera which would make life with chip space/post production/storage a whole heckofa lot easier.

I have seen footage from my camera at around 30mbps and it looks a lot less quality, but if I can't even render out of Vegas at any higher rat anyways, maybe I should shoot that way in the first place... you know?

Thanks guys.

Just use any of the MPEG-2 BluRay render templates and change the bit rate; it can go as high as 80.

Oldsmoke, that is a statement of misinformation - because the result for a render to do Blu-ray has to fit a spec and an actual delivery platform. Your numbers are only theoretical stream inputs and have no bearing on actual delivery.

No it is not. It is merely in reply to his question in case he doesn't know how to render to a higher bit rate.

Hide behind your cloak of technicality - but please qualify the practicality. It makes no sense to answer working editors with theories.

The OP asked a valid question and he got a a valid answer. The BD spec allows for video bit rates up to 40Mbps but maybe he wants to use it for other purposes with even higher bit rates.

Sure

I appreciate your answer OldSmoke,

Yeah, that answers my question. I am just so foreign to so much of this and trying to figure stuff out. Soon I believe things will change again (like the upcoming 4k) and I don't know if I can even preserve or it's it even useful to work at high bit rates.

But I did find what you were referring to and was able to see the different options. Somehow I missed those before.

thanks for the help, man.
