Sample File Comparing Before & After Reverse Telecine
I am not a professional and I take videos and make movies as a hobby but I found this thread very interesting so I decided to post a sample reverse telecine test I have done a few months ago using JES-Deinterlacer. At that time I was very interested in making 24p movies and downloaded the JES-Deinterlacer for that purpose. After some experimentation I decided that reverse telecine of an HDV file from HV20 is very time-consuming (at least for my purpose as a hobby) and since then switched to taking 60i videos and deinterlacing to 30p with another free software, MPEG-Streamclip.
To add to the above discussion, I believe HV20 does the 3:2 (or 2:3) pulldown in the manner it is described elsewhere on the web. (Just do a web-search using keywords 'telecine' or '3:2 pulldown'). This is very apparent when you deinterlace the HV20 video using JES-deinterlacer. You can see the 3:2 pattern when you compare the before and after clips. Attached is a sample jpg image I created after JES-deinterlacing one of my HV20 clips taken in 24p mode. Left column shows the frames from the original clip which shows 3 progressive frames followed by 2 pulleddown interlaced frames. In comparison, the right column shows 4 corresponding progressive frames extracted by JES-deinterlacer with reverse telecine option. I hope this helps. P.

Thanks Pedanes - I stand corrected.
Scott, I just ran HDV from a HV20 through QuickTime Pro and it frame dropped to 23.98 Pro-Res with terrible results. It looks as if it frame dropped interlaced video. So QuickTime Pro is not a viable option and as before, your footage must be processed: Options: 1) Buy Final Cut Studio and use reverse telecine in Compressor 2) Buy AE and Interpret footage (this is my favorite) 3) Use MPEG-Streamclip, JES, Cineform, ect. 4) Shoot on another camera which allows 24p Advanced (NLE detectable). -C |

Wow, thanks for all of the help guys. It seems as if my best option now is to go with JES... once I get going with the HV30 and am ready to convert, I may have a few more questions. Thanks again!

well if you have final cut pro, there is a 1080i 24p mode. don't have a canon, but thinking about it, since it might not be too big of a bear to mix hv30 with a jvc hd110 as my main camera. So has anyone done 24p/f with canon on FCP?

Just get a European HV30 - 25p - no pull down, no interlacing, no messing around converting.

Compressor is good because you can drag a whole batch of files into it. Apply the reverse telecine - and press submit.
