If you’re asking if the link you specified is ‘fixed,’ then
I would say that, rather than being broken, it was incorrectly formatted.

You’re link may have worked for you (idk), but it wouldn’t for everyone.

I re-wrote the link to the format that most people would see in the address bar of their browser.

So that you’ll be able to see what I mean, I’ll type it with spaces so it will show up as text (I hope):

h t t p : / / w w w . y o u t u b e . c o m /watch?v=CKYnVDnaohI

If you eliminate the spaces in the above line, then you’ll see what I specified.

Does this link show your video?

I edited your link url to be more generic.

Velocity envelopes are a challenge for me, too. I’ve tried to devise a way to manage the secondary effects, but without complete success.

That being said, I have an idea that may be useful in this situation:

There is a technique that may help you modify your keyframes to conform to the secondary effects of using the velocity envelope.

The Vegas Pro 10 manual describes changing the relative spacing of keyframes via alt-drag:

—
1. Click on the first keyframe, hold the Shift key, and click on the last keyframe in the sequence to select all of the keyframes.

2. Hold Alt and drag the first or last keyframe to scale the keyframes.
—

I would think that one could ‘fix-up’ keyframes in a project after applying an event envelope by using the alt-drag technique described above.

I think that the most important rule in any attempt to ‘fix-up’ keyframes would be to progress from start of project to end of project, chronologically on the timeline.

Hope this discussion gives you some useful info.

An idea to try:
In this test, border will show on bottom & right edges only.

-In timeline, select desired event.

-In pan/crop make clip smaller to show black (background) on top & left edges only. (Width of black should be same as desired width of border.)

-Apply border.

-In Track Motion, move edited event up & left and increase dimensions until event with borders on bottom & right fill the frame.

Thanks for the additional tip, John. I wouldn’t have thought about that possibility.

Hi, Bruce,

[Bruce Quayle] “By the way, there doesn’t appear to be any indication that I can see (other than the lack of said function) that this is on or off.
What a pain!”

I found a way to display this function’s state on the toolbar. If you go to ‘Options|Customize Toolbar,’ you can locate & add the button identified as ‘Show Video Event Edge Frames During Edits’ & add it to the toolbar. The button will display differently depending on the enable-state of the function (button looks ‘pressed’ when function is enabled).

Hi, Gary,

[Gary Badgley] “Maybe copy one of the last frames where there was no jitter over and over again creating this rock solid pause?”

This can be easy to do in two ways and, if I’m understanding correctly what you want to achieve, will work very well:

1.
-select a frame that you want to display during the pause,
-set video preview quality to ‘Best(Full),’
-click on the ‘save snapshot to file…’ button at the top of the Video Preview pane,
-locate the snapshot file & add it to a new video track above the existing one, and
-stretch the snapshot event to the time-length you need.

or

2. (if using Sony Vegas Pro)
-In the video event that you want to pause, right-click and select ‘Insert/Remove Envelope|Velocity’
-Locate the exact frame that you want to display during the pause
-(for accuracy, zoom your timeline to display each frame on the timeline separately)
-set your mouse cursor on the velocity line, in the video event, and on the frame you selected above (cursor will change to a hand & pop-up text will say ‘velocity’)
-right-click & select “Add Point”
-just to the right of the ‘point’ that you just ‘added’, and STILL WITHIN THE FRAME you selected above, add another point
-set your mouse cursor on the second point (cursor will chg to a hand), right click and select ‘Set To…’
-type ‘0’ (the zero key) and press ‘enter’
-Done

Hi, John,
Thanks for correcting my assertions. I haven’t had time to revisit my testing on this, but apparently my analysis was flawed. I’ll try to re-do the testing & post back.

Just thinking back, I probably mistakenly compared a clip rendered with both re-sample and supersample to the original clip (thinking it was rendered with resample only) on the timeline. I did verify as I stepped frame-by-frame that the rendered video had newly created interpolated frames that looked very nicely accurate & realistic.

In particular, the hand swinging as the person was walking showed reasonably accurate images of the hand moving through space between the location hand in the original clip’s surrounding frames (hopefully, I’m explaining it clearly). The moving hands in the interpolated frames, moving through space not captured in the original clip, looked just as realistic to me as the hands in the original source frames.

I was quite impressed with the quality of the interpolation & was thinking that James Souter may benefit from knowing what I found.

I am currently intrigued with one question:
Why didn’t James see new interpolated frames between the original source frames? See context:

James Souter stated:
1. [In preview the scene looks how I want it to look, however upon rendering it only renders the frames that are there and does not create any intermittent frames.]
and
2. [I have set the appropriate clips to “force resample” as well as tried “smart resmaple” but they all render as if “disable resample” was selected.]

and John Refrano stated (in response to my post):
[Resample is absolutely creating new frames between existing frames (i.e., “tweening”).]

Thanks so much, John. You are a huge benefit to this Sony Vegas Community, sharing your formidable expertise so generously. I appreciate your help and guidance.

Hi, James,

I believe that you may achieve what you’re hoping for, or at least closer to it, if you add a supersampling envelope to your video bus and us it to specify interpolation of your existing source video frames to fill in the project frames that fall between the original source frames.

As I understand it, the ‘resample’ task only ‘resamples’ each existing source frame (i.e. it will not provide new frames for source video that has been stretched to fill more time that it has frames available. It is useful when changing resolutions, pixel aspects, cropping, etc. The ‘supersampling’ task does create new, interpolated frames between the original source frames.

I’m using Vegas Pro 10.0 & in my pdf manual page 190 table at the bottom it says a “video bus [track] video supersampling [envelope] Calculates intermediate frames between the project frame rate to create smooth motion blurring.” There is more information there & other places in the manual, but the info is rather brief.

(my terminology:) You can set the supersampling envelope to integer values (e.g. 2, 3, 4, etc.) to cause creation of interpolated (‘tweened’) frames.

The manual also notes that there is a significant increase in rendering time when supersampling.

I just ran a test of 52 frames of source stretched to 208 frames output render and confirmed that this technique works.

-I placed on the timeline an event with 52 source frames of a person walking across a room.

-I stretched the source as far as I could (via ctrl+drag the end of the clip to the right) & confirmed via the event properties that playback rate was 0.250.

-I enabled the view of the video bus (View|Video Bus Track or ctrl+shift+b).

-I inserted a supersample envelope on the video bus track (right click the bus track header & select Insert/Remove Envelope|Video Supersampling)

-I dragged the envelope line up until it indicated ‘4’

-I rendered the project

-I inserted the newly rendered output video clip on the timeline.

-I confirmed that there were, indeed, appropriate & realistic interpolated frames with very acceptably interpolated images, including realistically repositioned elements (e.g. hands, etc.) in the interstitial frames between original source frames.

In other words, I started with 52 unique source frames and ended up with 208 unique rendered frames, each looking completely real and appropriate. Stepping through the resulting frames, I litterally can’t tell which are interpolated unless I compare to the stretched source. It’s very impressive.
