Deinterlace before editing/transitions?

[Rags]

Hi all,

I am new here on this forum, however, a lot of the best info I've gotten in regards to working in 24p with the HV20 has been here so I've read up some.

So... As it stands I have 1) recorded in 24p 2) used MPEG-slipstream to capture 3) used compressor to perform pulldown. This is where the train stops as I noticed some heavy combing/interlace in my footage. Reading up I saw that with my graphics card (GMA 950) and laptop monitor, interlace is common and using MPEG slipstream to deinterlace fixes this problem. Well, I did that and the footage is stunning so I'm happy!

My question now is if I am planning on making a short film for youtube and will be editing transitions and speeding up/slowing down my footage in FCP should I be deinterlacing before all my editing? Clearly the benefit would be that this would allow me to watch the footage as I edit without interlace but would I be better off editing with an HDMI monitor and deinterlace after all the editing?

Any help is appreciate!
Ben

After step 3, if compressor did it's job correctly "removing" pulldown, there should be no combing/interlacing in the generated footage. You should have clean 24p footage. If you still have combing/interlacing, something went wrong. You shouldn't need another de-interlacing step. Check your workflow.

Since you filmed in 24p (hv20's 24p in 60i) you want to edit in 24p. So pulldown removal before editing is correct.

Is there any reason for you that you used Streamclip for capture if you have FCP - what version? When you run your footage through compressor, interlacing goes. Your result is progressive footage. Open one of the files in Quicktime and check the clip's properties. Should read 24p.

However, when you pull your progressive footage into a 60i timeline, FCP interlaces it again.
