Video Quality Check - Emergency
on Sep 30, 2014 at 2:42:33 am

Hello everyone. I really require some urgent help and I would appreciate any advice from anyone.

For the past few days I've been editing away my friends wedding film. I've done similar projects in the past which haven't been any problems.

When it came to filming my friends wedding film they were shot in:-
Resolution:- 1920x1080
Frame Rate:- 25 FPS
Data Rate: 21 - 22 Mbps

There are numerous of clips. In total there are over 80 clips each of which are just over few seconds if not minutes.

When it comes to editing the clips I tend to use Sony Vegas and After Effects.

Today after countless hours in my studio, my friend said the final outcomes tend to have less quality.

On some of the clips I'm compiling them together and using some projects files that have been bought from the internet. Each of these projects file that I have bought are high quality (1080p)

Why is my friend saying the final outcomes of both the compiled version and the project files bought from the internet "are less quality". I'm getting really worried as I don't see any "less quality" videos.

When I'm using Sony Vegas I compile few clips together each of which have the spec mentioned above and render using the pre-template available within Sony Vegas:-

MainConcept MPEG-2 = Blu-Ray 1920x1080-50i, 25 Mbps video Stream > Customize Template > Video Quality: 15 > Two-pass

And start rendering the video files.

Please someone share some light, I urgently need advice on how I could improve my video quality.

Thanks

BUMP!

I'm really sorry for breaking any rules, just that it's an emergency.

Thanks

I guess you have to ask your friend, "Less quality than what?". A Hollywood movie? YouTube videos? You seem to be following a good workflow and if you are happy with the quality, perhaps your friend is expecting too much. But you have to understand what they are comparing it to before you can judge if it's "less than" whatever that is.

Hey John thanks for your response, he was comparing with the original clips that were recorded from the camcorder. So he's comparing the RAW video files from the camcorder with the edited video clips I have created. But there doesn't seem to be any flaws within the project, as you have mentioned my workflow is good so surely everything must be going well.

What do you think of my workflow? Could there be room for improvements?

Thanks

Make sure that Stretch video to fill output frame size (do not letter box) is NOT ticked under the Render As Render Options. If you do tick it, output can sometimes soften slightly.

Video rendering quality should only be set as good (not best) under the Project tab

Customize Template > Project > Video rendering quality = good.

You don't actually say what your project settings are, so I can't comment on whether there is an issue there.

My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 12 (x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6

Hey Nigel thanks for your response, on Sony Vegas I'm using the following template:-

HD 1080-50i (1920x1080, 25.000 fps) > Everything has been set to default, nothing has been changed.
Full resolution rendering quality > Best
Motion blur type > Gaussian
Deinterlace method > Blend fields

When it comes to Rendering, the following template has been used:-

Blu-ray 1920x1080-50i, 25 Mbps video stream > There has been minor "Customize Template".
Video Quality > High (31)

* Variable bit rate:-
Maximum: 30,000,000
Average:- 25,000,000
Minimum:- 20,000,000

*Variable bit rate, I'm unsure whether it was changed or left on default.

The original video clips where shot with the following settings:-
Resolution:- 1920x1080
Frame Rate:- 25 FPS
Data Rate: 21 - 22 Mbps

Thanks

The settings look fine. I don't know what your friend means by 'less quality', unless he is referring to the image lacking 'pop', which you can do by adding video event FX.

I usually color correct (white balance) and add a hint of saturation, add to a touch of contrast (0.032) to crush the blacks and make them look less washed out and a bit of color curves.

[Nigel O'Neill] "I usually color correct (white balance) and add a hint of saturation, add to a touch of contrast (0.032) to crush the blacks and make them look less washed out and a bit of color curves."
Yea, my rendered footage usually looks better than what my camera shot because I add Color Curves and a hint of Saturation. If you're not color grading your output this may be what he's referring to but if it looks the same to you then he may just be seeing things. Have him capture a frame from each and view them side-by-side and point out the difference to you.

One other thing you can do is put the source footage on track 1, put the exact same frames of the rendered footage on track 2, then change the Compositing Mode of track 1 to Difference. What you see in the preview is the difference between the two clips. The preview should be totally black if there are no differences. This should prove your point on way or the other.

I will test by adding color correct and hint of saturation and check if it makes any difference. Should I keep the default settings of the effects or would you guy's recommend to trial and error? Any other effects to improve picture quality, I think adding a bit of brightness or something similar can help?

Well for Color Curves and Color Corrector the Default does absolute nothing so you need to adjust them to taste. Start with a nice S curve and adjust from there.


[Farhan Ali] "Any other effects to improve picture quality, I think adding a bit of brightness or something similar can help?"
I would never use the Brightness FX. Color Curves is far more subtle and gives you more control.

Thanks John I will be testing it out with few of my media files.

Sorry but I've never done "Compositing Mode". I've added source on track 1 and rendered version on track 2. How do I go about to do what you have mentioned?

Click on the Track Composite Mode button in the Track Header for Track 1 and select Difference. That's it.

I've set Track 1 "Difference". On the preview screen there isn't much showing, very light/fade video, nothing major though. Does that mean the re-rendered version lacks on quality?

Whatever you are seeing is the difference between the original video and the rendered video. If the preview is completely black, there is no difference. The rendered video matches the original video in quality. Any difference that you see is the degradation in quality between the original and the render. The more you can see, the more degradation in the rendered video.
