Hey guys..

I updated to pro 11 and I'm working on a wedding right now... I'm adding a little bit of slow motion effect and I'm using dissolves from one clip to the nest. My problem is when I play the video back the clips that are in slow motion and the dissolves from one clip to the next the clips look fluttery or a little choppy.. I've never ran into this problem before and frankly i'm confused. I read that it's caused be interlacing and I need to deinterlace the project, however when I go to new and click on deinterlace and blend field it wont save it, it goes back to none. I shot the footage with a SONY FX7 in 1080i HD and I'm editing in HD 1080-60i, if that matters?

ANY HELP IS APPRECIATED!! I'm already behind on this video and now I need this issue cleared up quickly.

Thanks again for any help
Paul

On your slow-mo events (what Vegas calls a clip), right-click and select "Disable Resample".

And you also need to remember that you cant slow down
certain clips tooooo much, you will get that choppiness,
(unless its shot at 60 fps).

I've never had an issue before when I've used slow motion.. first time this has happened to me since I've been using Vegas pro 6..

Are you editing in HDV 1440x1080 Preset. Turn the deinterlace method to none. Make sure you keep your output to upper field. Don't deinterlace your footage.

If you are outputting to DVD, setting your deinterlace method to none as suggested WILL result in motion artefacts in ALL parts of the footage, especially where there is motion, either by your subject or when you pan the camera.

BTW, how are you delivering your output: web, DVD, bluray?
How are you reviewing or testing it: on a computer screen, DVD player, bluray player?
Are you able to test it on different players or setups?
Have you tried a different transition? Is this a standard Vegas transition or are you using a 3rd party plug-in?

I know that's alot of questions, but hopefully it gives you some ideas to work on.

My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 10e (x32/x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6

I set the deinterlace to blend however it will not save to that setting it reverts back to none.. so I'm not sure whats going on there???

I'm delivering it to DVD
I'm reviewing through the Vegas preview screen and then on a DVD player
I have tried 2 different players and settings and no difference
I have tried other transitions such as color dissolve or flash dissolve
and yes the effects are all from Vegas

This happened one other time and I ended out uninstalling Vegas then reinstalling it and it worked.. this time however it's not working.. I'm pretty frustrated over this, I'm not sure what else to do??

If you want a workaround try leaving the timeline native,which would mean leave the timeline 1920x1080 60i (or 1440x1080) 60i. This would be native to your source video. Do not deinterlace. Create a file 1920x 1080 60i upper field as your final product. This will not create motion artifacts.This is still your native resolution. This matches your original footage. If you play this master back on your computer using VLC Player it will look interlaced however then turn the deinterlacing on in the VLC player and watch it again. See if you are getting the desired result. If you do get the proper look your next step would be to use adaptive deinterlacing on your interlaced master to create your progressive master.You don't want to deinterlace the hole picture just the action.Autodesk Cleaner, or Virtual Dub (free) will do this for you nicely. Now you have a 1920x1080 29 Progressive master which will convert very nicely to a DVD,progressive or interlaced. Without deinterlacing the whole picture instead of just what you need.
