1080i re-encoding for kdenlive

Hey, I am trying to edit video I shot on vacation using my new camcorder.

The shots are all in 1080i 1920x1080@60fps.

Kdenlive will not actally play any of the video without serious frame drops although it renders fine. I've noticed that kdenlive does a pretty good job of re-encoding it into something that kdenlive can actually play.

So my question is can anyone with more ffmpeg or mlt knowledge than me pass me a command line argument that will allow me to re-encode the 40+ clips that I have so that kdenlive can edit them?

Here is a sample clip. The camera in question is a samsung.

There's a Transcode option, a common choice is DNxHD however I think there may be issue with interlaced material to DNxHD unless you are using a latest svn build.

I don't think i get what you mean about the transcode thing.

I need to transcode about 40 clips. I m using an svn version.

The camera is in the DB btw it's a Samsung hmx h200.

In Kdenlive: File (Menu) -> Transcode clips.
Select all your clips, and then choose a transcoding profile, DNxHD is often used. Make sure to check "Add clips to project", so the new transcoded clips will appear in the project tree.

Re: 1080i re-encoding for kdenlive

to convert before importing in kdenlive, select 1 clip, try to convert in kdenlive (copy the ffmpeg parameter , f.e. -s 1920x1080 -r pal -top -1 -flags +ilme+ildct -b 120000k -threads 2 -vcodec dnxhd -acodec copy %1.mov

then use in console

for i in *.MTS ;do ffmpeg $i -s 1920x1080 -r pal -top -1 -flags +ilme+ildct -b 120000k -threads 2 -vcodec dnxhd -acodec copy $i.mov; done

this would convert all MTS files in the dir you will execute this to .mov.
