Editing and rendering mixed formats

[John Rofrano]

I would work in a 60i project this way there are no surprises when you render because you will be rendering to the same format that you are editing in. It shouldn’t make a different because both formats are 29.976 fps so the timing will be the same either way, but I like to edit in my delivery format if at all possible just to be safe.

Thanks John. Very helpful. In the past when I’ve used progressive material. Usually dji or GoPro I have dropped it into the 60i timeline with no issues (other than the usual lagging problem) but my camera material has always been 60i. So this is good to know since I am switching to 30P.
One other thing that may or may not relate to the 30P/60i issue.
My ‘full resolution render quality’ is set to: ‘good’ should I change that?
Motion blur is set to : Gaussian
Deinterlace is set to: blend fields.
Any issues with those settings?

If you are having lag issues then I might suggest changing your project to 30p. There is always a trade-off but it’s hard to edit with laggy footage so you might try it the other way around. As I said, 30p and 60i are the same frame rate so there shouldn’t be any surprises when rendered. The only issue I’ve seen is adding images with thin lines that look perfectly fine at 30p but flicker at 60i. You wouldn’t catch this problem until you render to 60i if your timeline was 30p but… I hate laggy editing so I would switch to the a 30p timeline.

[Martin Seemungal] “My ‘full resolution render quality’ is set to: ‘good’ should I change that?”

No, Good is usually fine if you are not resizing (e.g., 1920×1080 project -> 1920×1080 render). The only time you would change it is if you are rendering to a different resolution, then Good probably won’t be good enough and you’d want to use Best so that it uses a better (but slower) algorithm for resizing. (I believe Good uses bilinear and Best uses bicubic if I remember correctly)

No, those are fine.

Great, thanks. Very helpful. If I do run into lagging and editing in 30p helps then would I be able to switch back to 60i before I render? any issues with that?

No issues but also no need to do that. Just render to 60i from your 30p project and check for any problems in the render to be sure. It should be fine.

Thanks again- editing and rendering interlaced seems to be working well. Have you had any experience using the MAGIX mp4 template and setting it to interlaced/upper field ? It’s default setting is progressive but I see you can ‘customize’ it to encode/render interlaced. Just curious if there would be any benefit to using the MAGIX ..which creates an mp4 as opposed to , say , using one of the equivalent ‘mxf’ templates.? in my case the XDCAM EX 35vbr

No experience and I would not do that. MPEG4 is a modern format designed for progressive delivery. I’m not sure why you are delivering interlaced (I assume you need to support some old broadcast standard for television) but interlaced is a thing of the past. Avoid it at all costs and tolerate when you have to. If you must deliver it, use a traditional interlaced format. I don’t think anyone would expect an MP4 file to be interlaced (even though it is possible to do that)

Thanks, yes–this is good to know. And I understand your point. It seems like a lot of the main networks are still broadcasting in interlaced format and therefore use Interlaced based/60i in north america and 50i in Europe and elsewhere. It’s unfortunate because I agree progressive is the way to go.
