Afaik ffdshow team is working on supporting/using multi-core for all codecs in it and last I read many codecs were still missing. Older version may support a wider range of codecs.

I saw Cineform Studio on your list, can it not transcode your mov's to avi? It doesn't use Matrox codecs but if you've installed Cineform then Lightworks should be able to read Cineform encoded avi's. It's also possible to make Lightworks export Cineform avi's using a trick posted on the forum.

I do batch transcoding with Avisynth and an ffmpeg based input filter as decoder, followed by virtualdub to encode to Cineform, although Matrox codecs work also, all called from a batch file. It's somewhat specialized for my situation (parsing filenames for recoding dates) but I'll see if I can make it something more generalized.

Dear Frans,

Thanks for your input...

I finally went back to transcoding one clip at a time, using RadVideo. It was the only tool I had success with. Someone with a deeper knowledge of transcoding might have gotten other tools to work, but my knowledge gap is rather large at this point.

But... I managed to get all my .mov clips transcoded, and linked to, and I'm happily editing in LW, so I'm thrilled.

I just ran into a problem trying to get an .mpeg file transcoded, but haven't succeeded yet.

Onward and upward...

I had the same problem importing video from a Panasonic video camera. No matter what combination of codecs and color spaces I tried I always had a white line / bar at the bottom that made the whole image jerk / jiggle up and down. Cropping two rows from top and bottom didn't help, but changing from 'fields' to 'frames' did. I'm just getting started with Lightworks, so I don't know the implications of the change to frames. Is there any reason why I can't just use 'frames' from now on?

Thanks!

@fireandlasers

Welcome to the forum!

Do you know if your footage is interlaced or progressive?

Hi, and thanks!

1) Should I start a new thread? I don't have a Canon EOS 60D, I really just wanted to reply to the above thread to add some of the keywords I had tried searching for to the thread that solved my problem.
2) Mediainfo says it's ScanType: interlaced.
3) In VirtualDub I'm having to add 16 pixels in width and change to 24-bit RGB to use the Matrox DVCAM codec and as well as change the audio from AC-3 to something else (currently trying MP3) to get it to input into LightWorks.
4) While I'm at it, here's all (some?) of the MediaInfo output:

I just realized it would probably be more helpful to post the MediaInfo data for the file AFTER transcoding in VirtualDub, i.e. the file that I am importing into LightWorks:

Also, not that it matters, but this is the 'short' clip... the other two are 1h5m and 35m.
