NTSC should be 29.97 (or 30fps) . Are you sure it says 25 for NTSC?

yes sorry 30fps, any ideas how I can get 60fps

Unfortunately PD won't produce in 1080p60 so the final product (assuming you are going to Blu-ray format) will be 1080i60 or 1080p30.

However if you set the format as NTSC the 30 fps will make the final file motion smooth with no frame dropping.

Perhaps PD8 will have full HD support as there are a few consumer level cameras appearing on the market now.

HI,
I've a Sanyo Xacti HD2000 - sitting in front of me waiting to be played with

mp4's are recorded at 29.97 frames per second.

If you're in a Pal set up (as I am) then the TV conflict notification will display when you bring video into PD - that's pretty standard. Please uncheck the always notification and click OK.

Video files used to display in the timeline according to frame rate and this would mean a difference of 5 frames if one imported a NTSC video into a PAL. BUT this is no longer the case, as the "block" of video imported reflects the length of clip. The bit rate per frame alters for video produced in PAL but the overall rate is the same for the whole clip even when comparing NTSC with PAL. Adrian (vn800rider) and I did a fast and dirty experiment with mp4 a little while back. Sorry I've digressed.

Now to 1080p. I did mention in another post using a customised template based on the 720p template for mpegHD - perhaps looking this up in PD7 will do the trick for you.

Like many cameras that have the ability to connect to a TV, one of the menu selections in it asks is what TV format - PAL or NTSC. This does NOT mean the video output is altered and it remains mp4 29.97 frames.

OK, I will play with the Sanyo in a while... and do video recording when my class 6 sdhc card arrives in the post - I've a lower spec card in the Xacti at the moment.

Hi Dafydd,
While this is true, if you render a 30fps clip into 25 fps there are still frame changes from the original sequence to maintain clip duration at the new frame rate which still results in noticeable jumping on panning shots. I still maintain if you shoot at 30 fps you should render at 30 fps.

I tried to search but couldn't find the reference. Can you please quickly explain again how you can output 1080p60, Thanks

Part 2 - 60fps no not in PD7 - it was intended as a reference to customising a 720p - sorry I should have mention that.

Part 1 - Take a look at the 3 test files yourself - they made interesting reading for me and Adrian.

I don't agree with your assumption of a frame rate causing jerky movements, it used to be the case but now we have blocks of data and the idea of an actual frame has become very blurred. Adrian mentioned to me he has seen jerky movements but it does depend upon what player he used with degrees of of jerkiness for some and others none.

Thanks Adrian for the information - very interesting reading.

Hi Dafydd,
jerky movements with frame rate conversion is not an assumption but a reality for my set up. I am not dissagreeing that AVCHD is not a simple matter of each frame being encoded then decoded for playback. We both know of the complexities of forward and back interpolation using I, B and P slices to recreate fields/frames from data contained in the file BUT it still has an impact if the data was written with 30 slices or 25 slices in it's creation.

The two files linked (if you are interested) have been created by PD. I made a 20 sec clip of an oval motion and rendered to AVCHD at 30 fps. I placed a time code in the corner to help demonstrate.

I then used this file as a "surrogate" clip from an AVCHD camera and rendered it both to 25fps and 30 fps (the links below).

My mediaplayer outputs both 50Hz and 60Hz to my Plasma which accepts both 50Hz and 60Hz.

The 30fps clip plays smoothly using 60hz output.
The 25fps clip is jerky in both 50Hz and 60Hz output.

I maintain that it is best to use a frame rate for production which is comparable to the original frame rate of the files being used.

OK, I'll take a peek at the links shortly.

CyberLink's R&D are looking into 60p and 60i - sorry no data - just say the issues are being looked at.
