As I recall, the old HDV cameras actually only print 29.97 to tape. When you select "24F", the camera adds a sort of consumery pulldown to the 23.976 to create a faux 24p look at 29.97.
The drag is that because the camera doesn't lay down a true 3:2 pulldown, there is no way to reverse telecine back to true 23.976/24. Essentially, the faux 24p look is baked in to the 29.97. And the faux 24p sucks.

I'm sure I am now showing poor double-posting manners, but I do want the post to get out there in a readable format.
I've never been clear on the etiquette regarding double posting here and on Avid's forum. Sorry if I've broken some rule; I was raised in a barn.I know I've seen this covered before, but, now that I need the information, a forum search or google search brought me nothing useful. So, if someone could point me in the right direction, I'd appreciate it. And please forgive me if I'm flogging a dead horse ("Media Composer" + "flogging a dead horse," interestingly, brings up 82 discrete hits on Google).I shot last weekend with an old consumer HDV camera (the Canon VIXIA HV40). I had it set for 23.976 fps, or, rather, to something called 24F, which I remembered—apparently incorrectly— as being true 23.976 (herewith to be referred to as 24). But I can't capture it in a 24 fps project. I got two error messages:"DigitizeWindow::ActivateDevices StartPassthrough failed with ePSIsStarting." and then"PMDIOVideoFifoStream::AllocateMemory - setup sizes are incorrect - m_videoPageSize: 512, m_videoBlockSize: 512, m_videoFrameSize: 0"If I attempt to capture into a 29.97 project, it does so happily and I get something interlaced and with duplicated frames suggesting a 2:3 pulldown. I am capturing, by the way, via HDMI through the Black Magic Intensity Pro 4K.I had other, newer, better cameras on this shoot capturing at 24 and I would like my project to be in 24. So, my question, finally, is, can I, and if so how do I, convert my HDV footage to true 24 fps?I am willing to sacrifice the audio, but would like the footage to remain at correct speed so I can sync it to my master audio. Obviously, if I could keep the original audio to aid in manually syncing, that would be great, but, again, not a deal breaker. And I am prepared to capture the footage and then do the conversion outside of Media Composer if that's the best option.Thanks,MartinSystem Specs:Early 2009 Nehalem MacPro4,1, 2 X 2.6 GHz Quad-CoreOS 10.10.5
