Smoothing image sequence
1st time poster. I am new to Vegas Pro (using 9). I have followed the several threads started by Hans-Joachim on May 2009. I am importing about 720 .png images into Vegas to create a video. Thanks to all the wonderful post’s, I have managed to come up w/ a somewhat decent video. However, the video still runs like a “rainbird” (small jerky motions). I tried to capitalize on Mike Kujbida post concerning still image length, overlap & overlap conversion. However, w/o knowing exactly what each of these settings does to the video, it is hard to adjust accordingly. I have tried the help glossary in Vegas as well as the same in the user manual, but cannot seem to understand how to use “crossfade”, “dissolution”, etc. to my advantage. I am certain that Vegas can produce a smooth video from a sequence of images, but how to get there & why is beyond my ability. Help?
P.S. the images were exported as .png out of a Google Sketchup Pro file. -

John, if this is a full image sequence (i.e. you have 720 images that you want to assemble into a video), follow the steps I outline in the Importing image sequences problem thread.

Mike,
Thk’s for the info. However, I’m still getting flickering effect. Attached is a clip of the edited image sequence (I hope)
Settings: Options – Prefs-Editing. New still image length set to 0.125, Automatic overlap… checked, Cut to overlap conversion @ 0.050. Images imported w/ open still image sequence checked & the media tap set as per your post Nov.27, 2011 @ 7:55 am. Video event: Reduce interlace flicker checked & Disable resample also checked.
This clip is only 300 some frames & is used as a test. The final will have just over 3,000 frames.I still seem to be doing something wrong!

John, if you imported these as an image sequence (is this what you did?), no editing or anything else is required as it comes in as a continuous file that you just drop on the timeline.

Mike,
Yes, the images were imported as a “image sequence”. The only editing I did, outside from the preference settings listed in the last post, was to group the video on the timeline & stretch it for a slower video speed. Actually,the video as seen on the post is not to bad, but when viewed on my monitor or on a projector screen to a client, it is quite jerky. The flicker of images seems to be worse when the camera “pans” rather than “walks”. I am wondering if this could be something inherent in the animation done in the modeling software!?
W/o the settings as listed above (default vegas settings), the jerking effect is worse.

John, sorry for the delayed reply.
Is the original animation set up to be 30 fps or something else (15, 24)? -
Mike,
The original animation was exported @ 10fps.
I found an excellent tutorial by Paul Russam on the SketchUcation form on the internet, that was very helpful w/ exports out of Sketchup (my software). Apparently, more fps results in a smoother video!! I went back into my software & started an export @ 30 fps. The processing time was 30 hrs w/ 11,345 frames. Unfortunately we had a freak snowstorm here which cut off my power, so the export was incomplete. I hope to start it again as soon as the threat of this snow storm has passed.
Anyway, in Mr. Russams tutorial he exports his image series into Adobe Premiere Elements instead of Vegas. I am on the trial period right now of Vegas, but do not know anything about Adobe Elements except the fact that the price tag is about $200.00 more than Vegas. I know you use Vegas, but do you know anything about this Adobe software program. If I’m going to invest the money, I would like to have the “better” of the two. Do you have any suggestions?
Back to Vegas & image sequencing. Will imported 30 fps image sequence result in a smoother video processed out in Vegas @ 30 fps?

[John Demers] “The original animation was exported @ 10fps.”
That explains why it’s so jumpy.
I had to work with a mechanical parts animation a few years ago that was done at 15 fps and ran into a similar problem.“Apparently, more fps results in a smoother video!!”
NTSC video is 30 fps (actually 29.97 but lets not split hairs here) so this statement is very true.
“Anyway, in Mr. Russams tutorial he exports his image series into Adobe Premiere Elements instead of Vegas.”
He must be a Premiere lover as it won’t make any difference which NLE you use.
“I am on the trial period right now of Vegas…”
Which version? Vegas Pro or one of the Movie Studio packages?
“…but do not know anything about Adobe Elements except the fact that the price tag is about $200.00 more than Vegas”
Adobe Elements has a list price of $150. You must be thinking of Premiere Pro which lists at $800.
“I know you use Vegas, but do you know anything about this Adobe software program.”
I’ve briefly looked at the Adobe offerings and always come back to Vegas as it fits my workflow better.
“If I’m going to invest the money, I would like to have the “better” of the two. Do you have any suggestions?”
Download the trial version of Adobe and see what you think of it.
“Back to Vegas & image sequencing. Will imported 30 fps image sequence result in a smoother video processed out in Vegas @ 30 fps?”
The result will be MUCH smoother.

Mike,
The trial version I am using is Pro 9. If & when I purchase it will be the latest version (11), I believe.
I seem to be having a problem importing .png files. I select my folder, highlight the 1st file & then check the box below for image sequence…. In my case the images range from 2001 to 211,762. However, down @ the bottom of the import window the range finder illustrates images 2001 to 29,999. This is not all the images. I enter the value of 211,762, but still only 29,999 frames are imported into Vegas. I doubt this would be the maximum limit of the software so what am I doing wrong?

“I doubt this would be the maximum limit of the software so what am I doing wrong?”
John, I’ve never tried importing that many frames so that may very well be a limit.
The workaround would be to import the sequence multiple times, incrementing the lower and upper frame numbers each time.
This would result in (if my math is correct) 7 sequences).
Drop them all om the timeline and see what happens when you press play. -
Is number 30000 missing?
