Deinterlacing Confusion at DVinfo.net

Mark Davidson · April 28th, 2012, 05:28 PM

Sorry to ask this when there is tons of info already written on the topic, but I'm confused.

I have a Canon HV30 that records 24p in a 60i stream. I just downloaded CineForm and removed pulldown on a sample m2t clip.

Some of the sources I read said to chose to remove pulldown only. Shouldn't one also choose to deinterlace?

Don't deinterlace; only select remove pulldown.

Thank you

I was able to convert two 65MB files to avi and remove pulldown. However, when i try to do a 1.3 GB file, HDLink quickly hangs up with a "not responding" message.

This happens regardless of the quality level chosen. I even deselected the i-frames checkbox.

My Win 7 64-bit computer has plenty of processer, 8GBs of memory and a dedicated video card.

I've turned in a support ticket but will try to remember to post back when the solution is found so other googlers may benefit. I hope they don't tell me to recapture the files using CineForm.

I tested many more files of all sizes and think I have it figured out.

The files that don't convert appear to have a dropped frame in them. When I watch the m2t files they have a hiccup in them. So the answer is what I didn't want to hear: I need to recapture.

One thing it took me a while to learn is that firewire cables are often bad or partly bad which causes dropped frames.
