I will be happy if you can clarify a bit Eric,

On1 - assuming the 1:13.03 duration event is a trimmed one, hence one needs all it's content to be at 75% , but if by setting it to 75% it's duration doesn't lengthen, the "new" 75% event doesn't have all the necessary content . And need additional manual help....

How this is acceptable by you?

On1b - I'll be frank I don't understand this looping thing and how to use it. I set it ON and still once I trim a tail past the raw video end, I'm getting the freeze.

On2 - I have the duration on since day one, but do you thing I should take out the calculator to find what is 1:13.03 at 75% in order to help VMS16? (we are mid 2019 now) why the % is shown only in audio? why audio % more important than video %....

@FayFen

Maybe this helps you

That "additional manual help" is done in a second. Never been a problem for me.

Usually only a fraction of the editing process consists of adding slomos. Some of it are done to fill gaps which then needs mouse-stretching anyway. Some of it needs to be adjusted to fulfill a certain creative look which is best to be done by mouse-stretching again. Some of it doesn't need to be an accurate percentage. So I doubt we talk about an all-users all-day editing job. Then why should investing another second bother. If such things matter a lot, Vegas Pro with its scripting facility is the way to go as it allows to highly customize workflows to the own needs.

@FayFen

1 - Yes it's acceptable to me but my use for slowing down may be different to yours. I use it when I'm hand holding scenic type shots where there's neither people nor vehicles. It enables me to steady the shot to an acceptable amount without resorting to Stabilser FX. Stabiliser FX crops shots with loss of quality.

1b - Something strange here. If your Preferences/Editing top box is ticked then when you add a clip to the timeline it should loop when extended. You can check by right clicking on the timeline clip and selecting Switches. The Loop option should be ticked. If it's not then something is wrong.

2 - j-v's video shows you how to achieve this. You need to watch for the black marker. Possibly not easily seen if you're working on a small screen in daylight.

Thank you guys,

Yes j-v, I noticed that mark about a month ago.

Marco, It's not an issue of how many times one needs to slowmo, it's a matter of is the software makes sense in the way the feature is functioning to benefit the user and not the programmer.

How many times one needs/wants to have the exact final frame of the shoot to be freezed by default? If that frame content was important to begin with the shoot would continued.

Eric, still I don't understand when is the loop ? say I have raw 1min video, I trim (LTC 23 till 33) and put on time line just 10sec of it (now it's an event of 10 sec ). when and how it will loop? loop just on preview playback or as multiple times on the timeline (2 loops = 20 sec) ?

** Well, I guess one can't have it all

You asked how this is accectable and I tried to explained why it is for me.

and put on time line just 10sec of it (now it's an event of 10 sec ). when and how it will loop?

When you make that 10 sec a subclip with the right settings in Edit?

@FayFen Looping - playing around with this I can see why it's probably causing you problems. When you extend a trimmed clip it ignores the trimming and includes the entire original clip. So your loop repeat starts at the original beginning of the clip not the trimmed beginning. The solution is simple. Once you've trimmed to your 10 secs right click on the clip and "Create Subclip". This then replaces the clip on the timeline with both the sub and original appearing in the Project Media bin. Your subclip should now behave as you expect when extending.

I guess ~30 years after I started editing I'm getting thick.

I know what "looping" is but I don't understand what it does here in preferences as a major default feature to be ticked for use. Looping isn't something that one does arbitrary, to loop smoothly the start frame should be just "next" to the end frame. other way it's a noticed cut.

So if one needs the same video twice he can just copy/paste and done with it.

I started by looking for a quick smoother flow to slowmo. I think Eric that looping as VMS does it isn't the answer to my 1b...

But "Looping" will only be smooth if the start frame (of the loop) is identical to the preceding last frame. Otherwise it will be a noticed cut. What is in the shots that you wish to loop?

Eric, I don't want to loop anything.

You raised that in your first answer so I jumped on it in order to understand this useless feature in the preference

Thank you.

Ok. Understood thanks.

I must admit that Vegas wouldn't win a beauty contest when it comes to slomos. Trying to make a slomo by stretching an event works fine as long as not an exact percentage is needed. When an exact percentage of slomo is needed you have to follow j-v's instruction with the disadvantage that you have to re-trim your event, also if the audio part should be stretched, you have to do this manually. Means: ungrouping audio and video and stretch the audio part separate. Also the rendering result of the slomo is very disappointing, due to the resampling.

My other NLE does make a much better job when it comes to slomos.

There's more to slomos not winning a beauty contest. My experience is that altering the playspeed in VMS causes the user to encounter several bugs, going back years, which have never been attended to. The problem is mainly with interlaced source material which isn't handled correctly. Other consumer NLEs that I've used or tried don't have the same problem. But as VMS is great otherwise I just resort to workarounds. If you'd like a trip through the past this old thread relates. Actually it's only four years old but contains some names who rarely visit nowadays

Yeah, like de-interlacing, rendering speed, missing fonts, stability...
