Choppy/blurry/Strobe like video
I am using the original PP and have just started working with video again. One thing I always ran into was choppy video when I animate the sources in PP.
For example, I will take a full or widescreen video then use the ‘crop’ effect, creating an ‘image column’ of sorts. I will then key frame that column to move, say, from left to right. Often times the source footage will also be in slow motion.
When I watch the rendered product on my computer, it looks okay. But when I export it, usually in MPEG2-DVD, I can see the fields clearly and it makes the image look nasty and blurred. Is there anything I can do to avoid deinterlacing and losing the resolution?
Thanks ahead of time!

Where do you view the MPEG? TV or Computer?

Both. When I view the mpeg in WMP or in Encore itself. I initially thought it was a render issue and once put onto DVD it would disappear. But it is the same way on the television set. I view all in NTSC, by the way. I guess I should mention that.
The result is comparable taking an image and not treating it before animating it in PP.

Venninator ,
What’s the bitrate for encoding? Have you tried on different DVD Players? How did you burn your DVDs? Seems a lot of questions, but DVDs authorization is an art (to sound nice).

I transcoded to VBR, with min BR being 4, Max being 9 and target being 6. I would then use encore (all still in NTSC).
I do have to correct myself. I just looked at the footage I exported on the computer (pre encore) and it is reacting in the same, blurry many on those animations.
Maybe it would be easier, Perry, to ask what the best practice is in animating video footage in the manner I described in my OP? Thank you for all the help, though!

>> Try using CBR for any video <1hr, yielding same quality, more compatible. (BTW, 9 is too high. Go no more than 8 if you have to.)

>> How do yo keyframe the slo-mo in PPro2? The slo mo by itself in 2 is not very smooth. But it shouldn’t be choopy all the way. If you have changed a speed in a key frame, the resulted change should be fairly smooth but the transition for the change may not. If it is choopy all the way, even viewing in your pc, then, we need to look into encoding issues.

>> Try my suggestions above. I don’t know if there’s a so called “best practice”, often editing video is an personal taste. The rendered product may be treaked, however.

Hi Perry!
I took your advice, but it still yields a choppy animation. Now, I have done two things:
1) When I exported, I exported in progressive rather than interlaced.
2)I also tried exporting into a full DV AVI clip, deinterlacing it and
then exporting CBR, progressive and so forth.The second option got rid of the stutter, strobe type shakiness, so I that suggests it is the interlaced fields in the animation that cause the issue. However, whenever there is a black screen, it looks really bad. Almost like columns that contain blocks that are different shades of black. This is especially noticeable with titles against the black screen, as the titles create a type of ‘ghost streak’ across the screen.
What I haven’t tried is leaving everything interlaced, then exporting to MPEG2 progressively. I also haven’t tried deinterlacing the whole project and then exporting it interlaced.
Does this shed any light? Thanks once more, Perry!
