My TV is the new Panasonic PZ700U plasma. I'm pretty sure that while it accepts a 24fps signal from a device that can output it (I don't own one) it applies pulldown to it before it displays the content on the screen.

Does it make sense to record in 24P (using the Canon HV20) if I can't see it in 24P anyway? Or am I missing something?

Good question. I am tackling this as we speak (I am in the process of dealing with a 1080/24p -> 480/24p downsampled video but the same issue still exists). Canon's HV20 24p video is hard-telecined. Canon did this on purpose, I think, to keep it from competing with their higher end prosumer cameras. You need to remove the telecine. Others, including myself, have posted techniques on how to do this using Linux and a tool called mencoder. I don't know exactly how to do this in Windows. I'm sure it's possible, but not exactly trivial. In short, it will require post-processing on your part. I am about to finish my first authoring of an SD DVD in 24p. Next week, I will test it out at my brother's house since I don't have an HDTV yet. I'm curious to see if I created a proper soft-telecined DVD... :confused:

Okay. Now let's say I figure out the post-processing and recover the 24p video. Can the PC/monitor show a 24p source without applying telecine? And could I get the video to show on my TV in 24p without the TV applying telecine? Do I need a TV that specifically states it can display at 24hz or some multiple of? I'm confused, as it seems like all roads lead back to 60hz.

I will leave this question for others who are more familiar with HDTVs (which would be many since I don't own one yet ;-) Now, with all the different types of HDTVs (lcd, crt, plasma, dlp, etc.), I would expect there to be TVs capable of handling refresh rates of 24Hz (or multiples thereof). If not, then someone please chime in...

Personally, I chose to film in 24p because I "just like" having the progressive frames and also it seems to be a more flexible format, e.g., it's easier to convert to non-NTSC standards like PAL and is also good for publishing on the web, etc. Also, I like the fact that I can author a DVD using the soft telecine flags (it appears you can do this for SD DVDs and Blueray, but perhaps not HD-DVD). Doing this gives me (at least) two benefits: 1) I can fit more video on a disc, and 2) when/if I connect to a progressive display (TV, upconverter, etc.), the result should be interpreted correctly (with 2:3 pulldown, I need to rely on the display to interpret it correctly; in the past, many TVs failed to do this correctly; see: http://www.hometheatermag.com/hookmeup/1106hook/).

Good luck,

It seems acquiring both a player (e.g., Blueray) and display (e.g., HDTV) that can both handle 24P directly is not easy to do these days. Looks like 120Hz displays are getting popular, but they are still very new and very costly. In the long run (when selection grows and price drops), I think 24P source will be supported. In the meantime, we just have to deal with the less-than-perfect 2:3 pulldown results. Here's an interesting thread related to this topic:

Does anyone else have a better source of information on this?

EDIT: Maybe the new 120Hz TVs *won't* solve the problem, after all :mad: Here's an on-going thread in AVS Forum:
