Video Compression capability in Vegas Pro Suite 21 build315?

MURRAY-LESHNER wrote on 9/29/2024, 1:32 AM

Hello:

I have Vegas Pro Suite v. 21 Build 315. I am making progress on the learning curve s-l-o-w-l-y but am confused by search answers for an array of other versions and option packages, so that's why I'm asking here.

I have had hit or miss luck (most likely due to operator error) with attempting video compression in the past.

Sometimes I can see that choosing a save/render-as template for a compatible format is a pretty safe way to not over-compress a video to the point it is unsatisfactory.

For example, I typically record MP4 video in 2K/1920x1080. I render-as Internet HD-1080/29.97 fps.

I have different video bit rates in my media depending which camera I happened to use. The 'native' video bit rate seems to be higher than I think is necessary for Youtube & social media.

Q1: Does choosing the Internet HD-1080 render-as profile imply compression resulting in some file size reduction, or are there other compression steps possible to avoid unnecessarily large file transfers?

Q2: Does VPS v.21 b.315 contain tools for further compression?

Thank you

Q1 - File size and compression will depend on the bitrate used. What are the native bitrates of your videos? Your mentioned render template appears to have an average bitrate of 12 MBps which I consider low. Whether there will be more compression or reduction in file size will depend on the bitrates of your source native files.

Q2 - Not to my knowledge but an add on Voukoder is often recommended and it achieves better quality at lower bitrates.

I think I have seen 14-42 MBps. My oldest (14 MBps) phone I think is finally ready for retirement.

I will look up Voukoder.

 

Thank you

In the render template, clicking on the 'Customize Template...' button opens a window where many settings can be customised including the bit rate.

The template name can be changed and saved as a custom setting for future use.

As a starting point, it should be worthwhile checking out YouTube's recommended upload settings:

Also, take into account that YouTube will recompress whatever media is uploaded to YT so what appears on YT may not look the same as the original video that was uploaded. I've read a few times that some people upload HD video as a 4K upload so that YT's compression doesn't affect the video as much as it would with an HD upload.

Here is a nice introduction to the concepts and interactions of video compression, codecs, file size, resolution, frame rate, bitrate, bit depth, and a bunch of other areas you will learn about while exploring for answers to your general questions about encoding.

After reading the article, you will probably have more questions than you started with; feel free to ask them here, using the information and vocabulary of terms given as a starting point.

With modern encoders, called interframe compressors, no two files will come out at the same size and bitrate, since each one is optimized for its unique image detail, motion detail, and format specifications.

Understand that as this is a public forum, you will get a variety of answers, theories, speculation, and some pure BS, in addition to the nuggets of information that are actually supported by facts; always check the sources of your information, and if it sounds to good to be true, it probably is.

This is not something that can't be learned overnight, but with years of hands-on practice, at least high school math skills, and making lots of good mistakes.

Above all, be patient with yourself. I've been in the technical end of the imaging business for 54 years, having started at Technicolor and Kodak. Not a day goes by that I don't discover something new or long forgotten.

Thank you...speaking of asynchronous learning, and Technicolor, I grew up with a black & white television.

I did not know until 1981/82 in college, that The Wizard of Oz was the first movie to use Techicolor in the Oz part of the movie. I thought Ted Turner had colorized another movie with red hair & purple eyes & objected.

People at school thought I was crazy (or was it them?) or had never seen the movie before. I had...just not in color.

More than you ever wanted to know about the difference between CRF and bit rate targeted approach to renders developed with weeks of completed staff work.

Analysis of Rendering to a Target Bit Rate vs Constant Rate Factor

I'm absolutely certain these data will produce more questions.

I long for those days when experiments and objectified test data could still be shared and discussed dispassionately among forum peers.

I am happy with the 1920x1080 MP4 quality after rendering with the Internet 1080 profile. I thought by storing on Dropbox & sharing, people could use the Dropbox previewer player or download, and not require login and storage space, but one person apparently logged into Dropbox and tried to download to his account, lacking enough space.

I personally don't need to compress video, & can't worry about every person with a data limit. For the people who complain posted videos aren't 4k, I say if they want 4K posted, THEY can do it as a public service.
