Is your auto-save having the same problems?

This is expected for the following reasons:

-If every 1 px line is not falling EXACTLY on a comp pixel, subpixel sampling will make it disappear in places.

-If your layer is scaled down at any stage, or if you are exporting at half quality instead of full, it stands to reason that a 1px line will disappear in places.

-jpeg is a lossy format, which means some information is dropped at export

I would recommend using a slightly thicker line.

Next to “Time Displacement Layer” is another dropdown, which defaults to “Source”. Set that one to “Effects and Masks”.

you can also use blending modes on the precomposed layer. Something like “screen” will leave only the bright parts of the image. You can use a levels or curves effect to crush the shadows and get rid of everything except the projections.

Hi, Allan. Try this:

– add your car layers above your forest layer.

-Use your forest depth map as a luma matte for each car.

-Use a levels effect on each depth map to crush the values and isolate the part of the image you want to use as the mask for that car.

Since your shots have 3D camera moves, there is no quick way to synchronize them using 2D transforms. If they are super similar as far as height and position goes, you can try doing a retime on one clip so that the orbit speed matches the other. Make sure you’re on pixel motion for your frame blending if you are slowing the clip down at all. Use timewarp if you need to slow it a bunch. Then use a mesh warp to bend it a little as needed.

You might also try warp stabilizing both clips first, using the ground (not the statue). Retime the clips to match orbit speeds as much as possible. Then tweak your transforms and mesh warp to dial it in.

Another option, and probably the best one, is to use photogrammetry techniques to create a 3D version of both shots. Then align them and re-create the camera move.

I can’t understand from your post what you are trying to do with the point control, but you can replace commas in text with periods like this:

s = value; //some text with commas
s.replace(/,/g, ".");  //replace the commas

If your source for s is a number, you may need to convert it to a string first using the toString() method.

Might be easiest to use a distortion transform to move the corners close to the right spots (use some horizontal and vertical guides). Then use a warp transformation to dial it in.

Having a screenshot of your comp might help us advise better. Have you tried parenting the B layer to A, and then zeroing out B’s position? This will work if their anchor points are what you are hoping to align.

The script I gave you will only work if there is already an active composition with a layer inside.

To answer your other question, you could add this line to your code to add a new text element and set the inPoint to 1 sec:

currentComp.layers.addText("New Text").inPoint = 1;

Also, app.endUndoGroup(); should come at the very end, but only if you’ve done this at the beginning:

app.beginUndoGroup("Name of your undo here.");
