1080i HD SEQUENCE PROBLEM

[Shane Ross]

You need to convert everything into the same codec. Mixed frame rates on a timeline are BAD. Fine for offline creative cutting, but when it comes time to finish, you need to convert everything to the same format. If DVCPRO HD 720p 23.98 is your main setting, then everything needs to be converted to that setting.

As for going from 720p 23.98 to 1080i 29.97…get a Kona 3. It will cross convert that in real time as you output, and does a bang up job. ALL of my deliverables have been 1080, and all of my edits have been 720…and we have used this card for every output.

Shane,

Thanks for the quick response. You wrote ” If DVCPRO HD 720p 23.98 is your main setting, then everything needs to be converted to that setting. As for going from 720p 23.98 to 1080i 29.97…get a Kona 3. It will cross convert that in real time as you output, ”

Does this mean with the Kona 3 I don’t need to convert using Compressor all my files to 1080i-and do the lay back properly out to HDCam ?

Thanks

That’s exactly what that means. The Kona 3 does a conversion from 720p23.98 to either 1080psf 23.98 or even 1080i29.97…all in real time as you play out the footage.

Bear in mind that timecode will be offset by a frame or three…so if you hit 1;00;00;00 as your start, it might start at 1;00;00;03. just adjust your in point to compensate for this. It is a byproduct of this cross convert process.

Hi, Shane

Just been following this thread and I had a question.

I have a FCP sequence in 720p 59.94, and I have some 720p 23.98 footage that was run through hardware to convert to 59.94, a test clip from Compressor converted to 59.94, and some other clips that are still 23.98 and haven’t been converted.

When I output the sequence as a 720p 59.94 quicktime and compare the frames of each, the result from direct output off the sequence looks identical to my eye, and the frame cadence matches as well (2 identical frames, followed by 3 identical frames, repeat).

I was curious if I was missing a major problem it could cause to output off this sequence with mixed frame rates, since as far as I can tell it looks completely unaffected.

Thanks!

Well, if it looks the same to you, can I ask HOW it looks? Does it look GOOD or BAD? I might think that the hardware convert might not be the best. But I can’t say without looking. HOW was it converted via hardware? capture cards don’t convert frame rates upon input, only output in my experience.

I have been able to mix 59.94 into a 23.98 and get the same results if I did it via Compressor, or the FRC tool in FCP, but not the other way.

It looks good to my eye and the cadence is correct when I go frame by frame. However, it is mostly stationary footage with little movement.

For the 23.98 that we sent to a house to be converted, I believe the post house converted the footage by outputting the original 23.98 quicktime to a deck.

I’m running the footage through a Matrox MX02 LE box to a 720p monitor, off of a 59.94 DVCPro HD 720p60 sequence
