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.

Finally was able to upload the jpg image file.

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).

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.

Can you make dvd's that will play on ntcs players?

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