what would you do to avoid this?

Use an ND filter so you can stop down the lens so you don't always have deep focus.

Is the problem this severe in the original files or did it become worse during the down-conversion? It could also be that you need to find a better down-conversion process.
 
hey this is hd to sd downconvert ? This is line skipping + nearest neighbour downconvert to SD probably,worst possible convert.
 
I agree- this is NOT the result of footage taken directly from the camera. I've never seen it ever even get close to this. This is poor post processing.
 
Just using a proper downconversion would be sufficient. No filters, etc, necessary.

As a previous poster mentioned, this almost looks deliberate. I downsize all the time and have never seen anything that bad.
 
*what if i need slow motion?ill have to shoot in 720p??
*frame differently?Ok in this particular video how would you have shot it?
*contrast reduces this problem?

Thank you
 
I must down convert all my footage as our country doesn't broadcast in HD.

Yes footage from the camera on a similar project i have is perfect,but down conversion brings all this...i use Sony Vegas.
As for my camera settings i always prefer not having allot of post processing work in terms of cc so i use the standard setting with sharpening and contrast half way.Is that a mistake?im having this kind of problem mainly with outdoor shoots...i don't know what setting to use for outdoor.

What should you look out for when shooting and your end result is to be on SD?
 
I find 720p on canon DSLRs totally useless in many situations, but this video is a whole other world: those artifacts are definitely not what you'll get from a DSLR, even at 720p

this is a video of a similar subject (a car), shot with a 7D at 720p60:

(beware: the sound is hurtful)

and this is a more crude example, again with similar subjects (boats):
http://www.vimeo.com/7231588

the first example also gives you a hint of what you can do if you have to shoot 720p60 and your subject is aliasing-prone: play with focus and DoF
but the best cure is to shoot 1080p, even if your final output will be SD (just use some proper downsampling algorithm, like bicubic, instead of nearest neighbor); 1080p still has moire/aliasing, but it's nowhere near what 720p has

Some lovely videos you've got there..especially the car one.what camera settings did you use?when grading did you sharpen it?any noise reduction or smoothening?
One last thing i didnt understand this part of your post '' (just use some proper downsampling algorithm, like bicubic, instead of nearest neighbor);''
 
they're not mine, I just went to vimeo and did a search for 7D 60fps

the last part just means "don't use an overly dumb method to downsample your footage to SD"; any normal method will work fine; that "bogart" thing the youtube video says it used is doing something WRONG
what software are you using?
