HINT - how to turn off frame blending at DVinfo.net

Bart Walczak · May 6th, 2008, 01:19 PM

Before you start putting clips on the timeline, select your video clips and go to clip->video options->frame blending.

From now on, any part of this clip that you put on the timeline will have frame blending turned off.

Stumbled upon it by chance today, but I believe this might be helpful to many people here.

Remember, do this before you start editing :)

The same goes for deinterlacing. But why Premiere doesn't allow this for multiple clips on timeline I'll never understand.

Thanks for useful tip Bart!

and why would I want frame blending turned off Bart?

I'm curious about this as well. What are the advantages/disadvantages of turning this on or off?

when your working in 24P,for example, if frame blending is on the clips appear to have a strange "fluidity" to them. As if they were some strange interlaced field order. They do not look like 24P, and it is most obvious if you export to a DVD. It is extremely annoying, and has been a battle for us at work for a long time.

This is of the utmost help to us, and I am incredibly grateful for this insight, thank you Bart, for this post. You may have just saved hundreds of headaches.

So just to follow up a little, is this then not an issue/necessary/of benefit if you only work in 60i?

Frame blending seems intended for interlaced footage, it is only a problem in progressive footage.

Frame blending also seems to help in certain situations where a clip's speed has been decreased.

I was under the impression that frame blending only applies to clips that have speed changes, and doesn't affect clips playing at normal speed. I haven't noticed a difference with it on or off with my 24F footage. Maybe I need to look again. Thanks for the tip.

Yep, a little further digging shows Adobe's assertion that this only applies when changing speed.

But I'm still not sure why it should be turned off, even in 24p mode, if you're not changing speeds.

I find that "Frame Blending" enabled seriously slows down render times..
Crisp footage takes a serious hit, never mind choosing deinterlacing method.

For me, personally, it's hit and miss, and i only check it if i absolutely have to.

All my interlaced footage is monitored through a broadcast CRT. Depending on the speed change and camera movement, Frame blending might be required. Otherwise, i've noticed that having Frame blend unchecked, gives me cleaner results..

When you try putting 50p footage on 50i timeline, you will understand why you need to turn off the frame blending... :)

Plus it does make rendering time about 4x as long as without it.

Oh, okay, got it. Does anybody do this? Does any camera actually do this?

So if I'm understanding you correctly there's actually no reason to do this if you're just shooting normal 60i video...

JVC HD-101.

Yes, if you're just working with normal 60i, no need to turn off frame blending.

Vince DAmbrosio · May 15th, 2008, 06:45 AM

Would this have anything to do with slower render times in a DV 24p timeline?

Bart Walczak · May 20th, 2008, 02:21 AM

If you're using native 24p footage, unlikely, but why don't you simply check it out :)
