Flicker problem on Slow Motion in Premiere CS5 at DVinfo.net

Steve Norman · June 16th, 2011, 08:41 AM

As a wedding videographer, I use a fair bit of slow motion. Usually slowing the clips down to 50%.

Using Premiere CS5, I get a lot of flickering in certain scenes - particularly on shiny jewelry, shots of trees in background (I assume its the light shining through the trees) and shirts and dresses that are heavily patterned.

I'm shooting using a Canon XHA1 and as I am in the UK, I shoot in 50i.

I had the same problem on a different PC using CS4 although it wasn't as bad.

Now I've changed the PC, upgraded to CS5 and even bought a new FireWire cable and the problem is still there and worse.

I use Flicker removal on these clips and this does the job in most situations but it seems like I have to use this on almost half my clips to make them usable.

Also when using flicker removal, if there is any movement in the shot (people walking etc), the motion tends to be a bit juddery and not that smooth.

If anybody can offer any solution to the problem, I would really appreciate it.

Anybody have any ideas?

You could try:
Always Deinterlace
Anti flicker filter
Frame Blend

Thanks for the reply Ann.

I can use these options and they do help - though if there is any movement in the shot - the footage becomes very stuttery.

I was hoping for a solution to the problem rather than try to add filters.

I cannot be the only person using a Canon XHA1 and editing in CS5 and using slow motion that gets this problem!

Try turning on frame blending for that clip.
