using MXO2 instead of Compressor to change fps rate?

[Nicholas Natteau]

Sorry everyone,

My mistake. The results were not as good as I thought. On one clip I had good results but not on the others. The end result was quite disappointing: up converting from 480i29.97 to 720p24 via MXO2 resulted in a choppy frame rate. I had selected “MXO2 APple Pro Res 720p24” in the log and capture drop down menu.

I guess there’s no fast way to do this then. So if I have to master in a 720p24 timeline…and I need to incorporate 480i29.97 footage (and I certainly can’t afford a Teranex), should I then just up convert via MXO2 to 720p29.97 and then use Compressor to change the frame rate to 720p24?

Thanks in advance,

– Nick

Yeah, I was wondering about that. The Kona 3 makes the footage slow motion, I wondered what the MXO2 did. Didn’t have a chance to test yet…I still will. But I was amazed that it worked.

[Nicholas Natteau] “should I then just up convert via MXO2 to 720p29.97 and then use Compressor to change the frame rate to 720p24? “

Nope, that’s my solution. And what the product manager at AJA said is what you should do.

HI SHane,

Thanks for replying, but I didn’t understand your last sentence.

Are you saying I should use Compressor for the frame rate conversion? I didn’t speak to AJA tech support about this but I will.

After carefully rereading your article on upconverting with the Kona 3, I had a Compressor question:
Because my WWII footage was originally shot 24P, should I not be selecting “reverse telecine” in Compressor’s Encoder window? Or instead should I just be selecting “best” on all those tabs?

Finally, sorry to keep asking about this, I’m just having trouble understanding the “720p59.94” up convert option. For me all it did was duplicate all my frames from 29.97 to 59.94. Is this not problematic when editing? That you wind up with twice the number of frames you originally had and that every second frame is a duplicate of the first. Or is it simply that 59.94 converts better to 24p than 29.97? Is that the reason?

Thanks for any further light you can shed on these intricacies.

[Nicholas Natteau] “Are you saying I should use Compressor for the frame rate conversion? “

Yup…exactly. Use the MXO to upconvert the footage…scale it. And then compressor to remove the frames.

[Nicholas Natteau] “Because my WWII footage was originally shot 24P, should I not be selecting “reverse telecine” in Compressor’s Encoder window? Or instead should I just be selecting “best” on all those tabs? “

Test and see. Do both, see what looks best. Only you, who has the footage, can know for sure.

[Nicholas Natteau] “‘m just having trouble understanding the “720p59.94″ up convert option. For me all it did was duplicate all my frames from 29.97 to 59.94. Is this not problematic when editing?”

Well, not really. Because that was the only option in the Kona (Matrox is the only one I see that has 720p 29.97 as an option), and I was removing those frames anyway, as we were working 720p 23.98. I wasn’t staying at 59.94.

[Nicholas Natteau] “Or is it simply that 59.94 converts better to 24p than 29.97? Is that the reason? “

It is the the Kona capture settings only offered 720p59.94. But the frame removal looked fine. Done it tons. Matrox has different settings, that’s all.

Hi Shane,

To go from 720p59.94 to 720p24 where you removing frames in Compressor like you describe in your article? In other words, going into the “Standard video compression settings window and selecting “23.98” (or in my case (Apple Pro Res) I would be selecting “23.976” according to your article, correct?

[Shane Ross]

Correct.
