Hi Folks
LWKS already has dual windows in the edit pane for source viewer and timeline viewer. What I'd like is to simultaneously playback two clips with different color grading settings to compare and choose which effect I would like to settle for. For ex: Duplicate the clips in the timeline, apply two subtly different color grading effects and playback both simultaneously in a left and right viewer pane... Is that possible? Or is there some roundabout way of achieving this by rendering first? I want to do this comparison live in-app without exporting.

currently I spend a lot of time exporting and viewing and going back into LWKS - because typically I dont pixel peep every frame of the clip in a comparative way when I opt to test a color grading effect.

If not - How much do you folks think it is worth as a new feature request?

Cheers
G

I Edit mode, you can drag and drop any object into the left viewer, even the sequence which is already present in the right viewer. By default the positions of the timeline markers of both viewers are independent. ALT+2 switches to synchronized playback, starting from current position, so called Twin Play. ALT+1 switches to single play. The drawback in Fixed layout is that you have to switch to VFX mode, which shows only one viewer, to adjust the effects. In Flexible layout you can open multiple viewers and timelines side by side with the Effects panel, which is more convenient, in this respect.

Drag&drop from a bin, or a filter G0bble, not from the timeline.

Ok, so you mean apply a VFX and then add the clip to a bin and then drag it from there? Will try once home ...

I don't think so.

Provided there are two viewers open in the EDIT tab:
- Create two cues, one at the beginning of each color-corrected segment in the Timeline.
- Search the sequence you are currently using in the bins sequence filter.
- Drag the sequence into the Left Viewer. Now you see twice the same sequence based on the same timeline, but possibly with different positions. Where the large timeline shows the position in the right viewer.
- Position both viewers on different cues.
- If you press ALT+2, both playback positions will move at the same speed, keeping the previously set position offset.

But there are also other possibilities.
For example, you could copy the sequence and create the alternative color correction in the copy instead of experimenting with different versions in the same timeline.

By the way, you can also apply two Lightworks color correction effects in the same segment, and quickly switch which one should be active.

Make as many copies of the edit (or just the section of interest) as needed - tweak and compare - be sure the favoured version is placed into the working edit.

Make an appropriately named bin - to keep the appropriately named rejected alternatives - in case one might like to revisit the decision. There is no limit to the number of edits one can have in a LW project - a very useful LW feature.

This worked!! Thank you so much!

PS: After I change the VFX, I need to drag the sequence into the left pane again for it to reflect...

No, not exclusively, after changing the settings in VFX mode and switching back to Edit mode, to update the player (the left viewer), you can also switch focus from the right viewer (the recorder) to the player, e.g. by clicking on it.

One could also work in Flexible layout where mode switching is not required.
