A Matter Of Time? Rendering???

[bill in pa]

I’ve been working with the program for sometime with success but
lately have been concerend with my video projects in the time
involved. In the past most of my video work was confined by simply
editing out parts of a selection or may be cutting a scene here or there.

Now projects are taking a slightly different turn where by I am now setting
or being required too render the entire video with the program. What has me
wondering if I am missing something or doing something wrong.

The qualities of the video are just standard and the settings I am using to
do the rendering are the following: 1920 x 1080 @ 30 frames per second.
This all comes from the profile within the program. Additionaly no check mark
is placed in the box at the top same as project settings tab, for bottom box, the
smart render is checked. The computers cpu is running 95% and the ram
is at 50%. What has me confounded is that it takes this computer about
8 hours to render a 2 hour video using these settings. Does this sound correct
or am I missing something? I should add that all the videos require considerable
cropping.

Best Wishes to all on board, stay safe

I know you have provided a good amount of information, but some things you have left out will have a bearing on the time a render will take. You have given us the output properties, but you don't tell us what the input video properties are, whether they are all the same, and where they came from (camcorder, smartphone...)

Do you apply filters? Some of the filters that come with VS greatly increase render times, and perhaps even more than four times the real time you are experiencing.

And what exactly do you mean by "cropping". To me, and I suspect others, cropping is reducing the size of a video on screen by chopping a little off the top and bottom and sides. You, however, might be meaning that you are reducing the *length* of a video by chopping a bit off the beginning, another bit off the end, and perhaps chopping bits out of the middle. So which do you mean? If you mean it in the way I mean it, then that will change significantly the nature of the video and thus lengthen the render times.

You also say you have SmartRender turned on. SmartRender is of course designed to speed up rendering. But it only works if the original properties of the video and the properties of the outward rendered video are the same. Moreover, it also only covers those parts of a project where filters or other sorts of editing have not been applied. So if, as you say, you have done a fair amount of editing work, SmartRender would in that case have only a minimal effect, if any...

A two hour project is a pretty large one. If it were a 10 minute project which took 40 minutes to render, would you worry much about that? I guess what I am trying to say is that depending on what editing you have done and the filters applied, as well as the properties of the video, 8 hours rendering of a two hour project might in a number of circumstances be regarded as not too bad!

Another reason for the long render time is of course your "low" end system

The software I use takes the properties of whatever it is recording if possible
so basically they are the same. The signal it receives is through cable
tv and so it remains static, at least through one program.

Working from within the program itself, I believe that it calls cropping as
a filter. Your interpretation of it is exactly the way I use it. Some film from the
front or beginning, some from the end and from the middle or
top and bottom. Now to address your remarks about occurrence. The
front or beginning and end. The entire film is then trimmed because we must rid ourselves off those annoying black bars! Also, I enjoyed your remark about a ten minute project!
Those were the good old days, I haven’t done any in over six years.

Finally, from your tone on the closing paragraph, leads me to believe that I was worried
about nothing. I’ve tried to explain as best I could, that every part of the video
is touched by something of my doing. Either by trimming the front and back or cropping the entire film. Thanks again for your time, I know how busy you are.
Stay safe.

In passing (en passant as the chess freaks say), you've pretty much admitted what Ken was suggesting about smart render not having much impact. So can I suggest you post 2 things:
- a screenshot of the properties of the inputs from cable TV (you must have saved the file, import it, select the clip/s and then rt-click and select the properties item in the context menu: a panel will appear with the properties of the clip. Press 'print screen' key on then keyboard, and save the file as a jpg image, re-size (use Paint?) to no more than 950 pixels wide and then attach to a post here. Advise if they are the same for more than one clip if you are using several.
- a screenshot of the render properties you have selected: the share page as you set it up before pressing the 'start' button.
