Mixing formats - seems to work so am I missing something? at DVinfo.net

Stuart Boreham · December 8th, 2009, 05:35 PM

I recorded (all running at once) 5 mins of 5d at 1080 30fps, 7d at 1080 25fps, mp3 on a yamaha dictaphone type recorder at whatever, and Ex1 at 720 25p. Dropped them all into Edius on a 720 25p timeline and lined up the claps I made at the start, checked the claps I made at the end et voila - all in time perfectly, both uinconverted .mov and after the converted to Canopus HQ as it runs more easily on the timeline.

From what I had read I was expecting all kinds of nightmares. Admittedly I have not checked for video movement oddness and artefacts, the cameras were all resting on my workbench.

It looks like Edius just converts them to the same fps. Is that what you would expect? What am I missing here? And what will the 5d firmware do that Edius is not doing natively?

Have you tried using a 1080 time line with similar results? Also, which version of Edius are you using?

It's likely that the 30p content will be dropping every sixth frame - or blending frames - to create 25p.

I have'nt tried it on 1080p but there I se no reason why it woudl not work. Will have a go later.

It Edius is dropping frames is that any different/worse to what cineform would do?

Yeah, works fine on a 1080 30p timeline as well :-)

No one said it wouldn't work, it's just that like Jon said, you're 30p to 25p footage will be less than desireable (much worse than using 25p out of the box) and on longer clips, you're liable to run into audio sync drift for two reasons: (1) the 29.97 vs. 30.00 fps thing, and (2) you're using different word clocks on all of the devices and the devices aren't jammed and don't have timecode -- hopefully #1 will go away after the new firmware, but #2 will be staying with us for a long time to come.

You're using Edius--of course it will work as advertised. Different frame rates, aspect ratios, resolutions, whatever you through at it, its supposed to play it back. Buffer might drop at change points but otherwise...
