Yes as I suspected flicker was indeed an issue at 60fps. Had to shoot 50fps/25p with a 45 degree shutter.
Flicker wasn’t horrendous at 60fps and I think it might have been possible to eliminate it in post.
My conclusion is that I don’t believe it is possible to shoot at 60fps under HMI lights drawing power from 50hz mains. Please correct me on this if I am wrong.

Hi Jerry

I have feature film clips that I was given as Apple ProRes 422 HQ 24p files and wanted to keep them as high quality as possible. The sequence was started as an HDV sequence because that is what everything else was shot on.
I have tried copying my HDV sequence onto sequences set to the Apple ProRes 422 HQ 24p and Apple ProRes 422 HQ 1080i presets and I have also tried exporting directly from the HDV timeline. It plays ok in both the HDV and the ProRes timelines. It exports fine from the HDV timeline. The Audio sync problems only occurs on export with the Apple ProRes codecs.

Audio settings are 48khz, 16-bit, channel grouped, stereo.

Editing timebase is 25 – I can’t seem to change this and wondered if this was an issue when editing with both 24p and 50i source material.

Thanks
Jim
