Warning: may be dumb question. re: clear freeze frames

I hope this isn't too dumb of a question but...you know how when you pause digital sattelite (using Dish Networks' "Personal TV" or Direct TV's "TIVO")you get a nice clean image? Is there a way to do this in V4 ?
TIA,
Randy

Insert a velocity envelope on a clip and bring it down to 0% - should be clean as can be...

Another way is to mark your frame and render that fram as DV.avi best render....then take that frame back into the timeline for as long as you want. I like phils way better- but this is an alternate way

Sorry guys, but I guess I wasn't clear enough; I meant on a rendered mpeg2 or .avi.
Thanks,

What happens if you just press pause on your player? It's not clean?

Thanks for your patience Philfort.

>>What happens if you just press pause on your player? It's not clean? <<

Not really, depending on the frame you pause on it can be very blurry. When I pause on a commercial DVD or sattelite TV it is always in focus and could actually be used as a still. I have a feeling this has to do with shutter speed selection while shooting more than what one can do in post, but I've wondered this for a while, I've just always been too embarrased to ask. Perhaps someone could suggest a book that deals with this kind of dumb questions.
Thanks againPhilfort,
Randy

You probably have it set for interlaced you need to set it to progresive when you render. When you pause that blurry effect is from two frames showing on the screen at once when you pause it. DVD's are almost always progressive which means that those frames are blended to gether so there is no interlaced frames. Hope that makes since, just make sure when you render it you set the field order to none (progressive)under the custom options when you are ready to render the file.

Thanks Shogo,
Now I'm really confused, I thought if the final destination was for TV it needed to be interlaced. I've been using the default Mpeg2 render. I'm willing to test this though, are you saying go to render as/mpeg2/custom/video/progressive scan?
Thanks again Shogo,
Randy

I disagree with the need to set it to progressive. On many (if not all) DVD players a freeze-frame is actually a single field that's been 'doubled up'.

As for why Randy is seeing blurred stills, I'm not sure. I think we need more info. Randy, what processing (if any) did you apply to your footage before making the mpg2 e.g. did you deinterlace it? What template did render the mpg2 with? Was you source footage DV or analog?

none, (that I'm aware of )

>>"What template did render the mpg2 with?"<<
the default (that everyone seems to use to author in DVDA)

>>"Was you source footage DV or analog?"<<
DV

Thanks again Scott,

Hmm, not really sure what to suggest.

Maybe your original DV footage was not in perfect focus?

I BEG YOUR PARDON!!! (just kidding)
No that's not it, I think once again I haven't been clear enough...these are sports highlights videos with a lot of fast movement. After doing more research I think I've discovered I need to shoot in "Frame Mode" instead of "Normal Mode" with my Canon XL1S. I don't think there's anything I can do in post. I was hoping "super sampling" or maybe some "magic wand" or something could improve them but...maybe not.
Thanks Scott,
Randy

Ahh, I see.

When you mentioned the still was blurred I assumed it might have been focal blur - but, since it's fast action video, then you're seeing motion blur. Basically, the shutter speed needs to be faster in order to capture the motion 'instantaneously' so your original hunch about the shutter speed being too slow is probably right 8o)

Cheers,

Scott
