Worst case it should ask you if you want to convert to project settings.


That strikes me as being the most convenient way from a user perspective.

To return to the original thread topic, which is a feature I also would like to see;
I see no reason apart from opinion why Lightwork in a (near) future shouldn’t be able to import footage with frame rates differing from the project frame rate. Please do not confuse input frame rate with output frame rate - broadcast standard or not.

Remember that the speed tool already today plays clips at whatever speed you set, playing clips with a different input frame rate at “real” speed is essentially nothing different.

Another thing is what to do with the missing or superfluous frames, the easiest and most crude way is to simply duplicate or skip frames, while blending necesscary frames is more pleasing to the eye - within limits!

One solution could be to automatically (import settings!) import the rate deviating clips into individual subclips (or syncs??) with appropriate video speed correction set and some ‘frame-rate-correction-eye-pleaser-blending-effect’ already applied. A concept that wouldn’t change Lightworks. The ‘frame-rate-correction-eye-pleaser-blending-effect’ could also be useful in conjunction with the ordinary speed tool.

If it’s not obvious – I like Lightworks very much, more and more as I use it, the exact reason why I make this suggestion since I think it would make it even more versatile.

Kind regards, BjornE


Anyway, I have begun using LightWorks and this has been one of my extreme problems, because I shot a movie with two parts, one in 60 fps, and 1 short part in 29.97 (windows media standard) and it didn't allow me to combine them.

This is a no brainer. I would love to be able to change the rate of the project as well.

This is more of a technology question than a features one.

The point is that if you have to convert from one framerate to another, in most cases, you're going to reduce quality. That's because anything other than the original framerate is going to have frames where there weren't any in the original, or is going to be missing frames that were in the original.

And it's easier to go between integer-related framerates (say, 60fps to 30fps) than between weird fractional ones.

(You get the same problem when you try to change the pitch of an audio track without altering the length)

You can throw processing at it - massively oversample and then filter, or do motion interpolation - but these are, realistically, beyond the scope of of a system focused on editing.

It's far better to get your footage in an optimum, consistent format before you start editing, using specialist software/hardware to do this. Or better still (and I know this is unhelpful in the current discussion) don't use multiple framerates in the first place.

(By the way, I know there are NLEs that do this, but, realistically, how good are the results?)

You're absolutely right and, given a choice, I would have had all the directors of the films I've been in use the same frame rate or, at the very least, the same aspect ratio. Unfortunately, 'tweren't the case. Such is the dilemma of the working actor who wants to put together a demo reel.

Unwatchable, which is why I was trying to redo it with LightWorks.

Thanks for taking an interest.

No problem. I hope you find a suitable solution.
