24 fps 720×405 > NTSC Digi for Air??
Hey friends,
SO i was given an Animation quicktime that is 720×405 @ 24fps which needs now to be layed off to Digi Beta for possible broadcast.
I did a test letterboxing it in quicktime to 720×486 > then i brought it into Compressor and did a standards conversion 10-bit NTSC. The creative Director does not like the “jitter” created by compressor in adding duplicate frames so now he is suggesting bringing it into After Effects and “adding fields”.
I dont know AE yet just started ;earning it and I am curious if anyone can explain what he means and also any workflow suggestions or advise you guys might have not involving AE would be great too – was my process totally wrong?
thank you

I would just use a Capture Card like the AJA Kona series and have that add the proper pulldown when you layback to tape. You will need a capture card anyway to get it to Digibeta. The Kona does a good job.

When you brought it into Compressor to do your standards conversion, did you make sure Frame Controls were on, and that the Retiming Controls Rate Conversion was set to High Quality Motion Compensated. That should do a pretty good job of retiming your shot, but in any event regarding After Effects.
When he says add fields, I’m not entirely sure if he’s referring to a specific effect or what. Within After Effects, you can bring in the footage and interpret it as 29.97. The other thing you can do, is lay it into a timeline that is 29.97 and enable Time Remapping to extend it to the proper duration. Make sure you set your Time Remapping settings to Pixel Motion, and not Blend to get the highest quality result. However, you’ll have to precomp it, and make the precomp longer than the actual clip to give you the slack to time remap.
There’s a good tutorial here https://www.videocopilot.net/tutorials/speed_variation/ Though if you haven’t used After Effects much, it’s not the most straightforward thing.

Hello
He actually showed me what he did and it was in fact the first method you mentioned…now i am going to just bring into FCP and layoff.I also did check the options you mentioned in Compressor but the resulting file just was not what he was looking for HENCE his use of AE to make it less jerky or jittery – adding fields was a better solution and makes me want to learn AE immediately.
thank you

It was time remapping with AE? Glad it all worked out. If you’re trying to learn after effects, I can’t recommend the Cow’s Tutorials and VideoCopilot.net highly enough. I learned After Effects soley off of those two.

hey mr. sanchez
so to answer your last post – no it was the FIRST thing u mentioned – fields – not time remapping – however looking at the footage now all i see is that it is interlaced where as before it was not and also it is obviously not repeating any frames.

Adding fields by itself might make it play smoother on an NTSC monitor, but the issue to get it to Digibeta is adding pulldown, as Shane noted. Kona is your best option. Don’t know if the BM card you have can do this.
Have a wonderful day.
