It's a consumer camera and pulldown is added (most likely) for 1080i standards compatibility. It makes it so the camera can simply plug into most HDTV's and display correctly.

I suspect it might be due to B frames added to the encoding process.(an option in the latest MPEG Streamclip) I can make a version without them and it might play back more smoothly. The only reason I made a high bit rate h.264 was to try and keep the conversion as close in quality to the original m2t as possible.

Unfortunately, I don't have the ability to do HD WMV's on my G5.

FYI,
The clip plays better using Nero Showtime (I just bought Ultra 7 Enhanced), although still somewhat jerky.

This 24p raw file plays flawlessly in Media Player Classic using DScaler 5 IVTC mod (72hz display at 24fps is best)

Barlow, Do a google search for flip4mac and see if that helps.
(Windows Media® Components for QuickTime player should be free)

So if it is a normal pull down, we should be able to use vegas or cinaform, correct?

correct, fcp's cinema tools work fine with the footage i've played with thus far. you have to set the removal pattern manually, but once you figure it out it's smooth sailing.

I've already downloaded and used the demo. It watermarks everything now.

Chris Sorensen March 23rd, 2007 04:58 PM

There's a free version of Flip4Mac that adds a wmv plugin for playback. Doesn't encode but you can play.

Barlow Elton March 23rd, 2007 05:09 PM

Here are some (hopefully) pc friendly clips: divx and wmv

http://media.dvinfo.net/canonhv20/hv20108024p.divx (28 MB)
http://media.dvinfo.net/canonhv20/hv20108024p.wmv (25 MB)

Something's wonky with the wmv. I installed the flip4mac demo again and it will encode, but the clip gradually gets a greenish tint. I have no idea why but it should play ok for most.

Ah. . . the joys of living in a pulldown free PAL world ! :)

Fergus Anderson March 24th, 2007 02:50 AM

Lee do you know how the 25p raw files will play? In VLC will they show interlacing artifacts as they are in a 1080i stream? What will be the effect of the various deinterlacing options such as blend fields in VLC for playback?

How will Vegas be able to handle the files?

Cheers

apple tv
 
Ok wow, I REALLY like the direction of this.

http://stevenbothe.com/up/hv20-raw-24df-AppleTV.mov

720p single pass, apple tv compatible, basic warm processing, sheer for intermediate codec and pull down removal via cinema tools of course

no strobe, just smooth 24p

AMAZING I THINK!

I'm going V1U, but gosh, this is AWSOME for b-roll guys!

I thought there were interlace artifacts in the window awnings, but it was just shadows from fire escapes, hahaha. First try I was really disappointed, played around a bit with my settings, and OMGOSH, I LOVE THIS NOW!

I can't wait to see what comes out next from Sony and Canon!!

Indeed. I'd almost buy a PAL version of the camera simply to be free from this annoyance.

I'm sure the actual 25p PAL version of HV20 footage won't have interlace artifacts at all. It's carried in the 1080i stream, but it's pure progressive.
