Ah - I don't have enough room for 30 hours of Cineform. But my edit will be about 30 minutes so I should have plenty of space for 30 minutes of a YUV uncompressed 8-bit file. I'll certainly look...

Thanks loads for the reply. I did consider converting my 1080/50i clips to 25p or 50p before editing. Unfortunately, this option isn't really available to me because I have 30 hours of footage and...

Hi Marcus,

Thanks for the links - I'll take a look.

For this project, I think I've found a workflow that I'm happy with:

1) Shoot 1080/50i
2) Edit as 1080/50i
3) Render out the completed,...

Is there a way to make AVIsynth multi-threaded to use multiple cores? I guess not.

Very good work - thank you.

Please may I ask what settings you used on the camera? Auto-exposure? 1080/60i? Shutter-speed?

OK - thanks for the heads up. 200fields-per-sec (converted to 200fps with MVbob) is still very useful. It's higher than an SR3-high-speed can get (120fps) so I'm happy.

I have to say that I'm...

I've been playing with some DV interlaced footage and PPro 2.0's "always de-interlace" option seems to definitely soften the image. AviSynth with MVbob produces a good image (and doubles the frame...

Thanks for the reply, Ian.

What frame rate did you use on the HV20? 1080/60i?

Thanks loads for the reply.

When you say "it uses both to extract the best vertical res" does that mean that it blends and averages the two fields (i.e. that it produces ghosting)?

How does HD-Link de-interlace 50i to 25p?

How does HD-Link de-interlace 1080/50i to 1080/25p? Does it simply throw away one field? Or does it use smart motion-compensation like AviSynth's MVbob and then somehow halve the...
