cant find the resize-resample for the video to be 1080p on youtube

The two rectangles are different shapes.

Therefore, you can crop, you can stretch (distort), or you can live with bars. These are all possible using track motion.

So if i resize it it will be very distorted right? There isnt a preset that i input"video size "and doing stretch to fit by defult?

Yes it will stretch to fit the screen by default if that is what you want it to do.

When you stretch your video to fit a rectangle that is a DIFFERENT SHAPE than the shape of the original rectangle, we call that distortion because the vertical or horizontal aspect is stretched horizontally or vertically, replacing the bars with an image that is too fat or too skinny. Surely you are able to visualize this.

Wazeka, the way I would address this is to use pan/crop to crop the clip to a 16:9 aspect ratio.

I used 4K Video Downloader to get a copy of your example clip. I'm not sure what size you uploaded, but the largest I could download had an image size of 1146x720 pixels.

I use the pan/crop to resize clips often, so have created an excel file with a set of 16:9 pixel ratios. Since your file has black padding on the left and right, the best match in my spread sheet is a pixel size of 1136x639 pixels.

I loaded your clip into a 1920x1080 project, used a pan/crop setting of 1136x639, and the resulting rendered clip has no letterboxing (black bars).

Here is a video illustrating each step:

It begins with a snipping tool snapshot of the mediainfo report, showing the pixel size of the clip I downloaded.

Next, your clip runs and, because it is so short, is followed by a longer frame grab. These show the letter boxing.

After that comes a display of the project settings and the pan/crop settings.

FInally, the cropped clip runs, followed by a frame grab, showing the letter boxing is gone.

If your clips are 1650x1050, then the nearest 16:9 ratio is 1648x927, and those are the pan/crop values you should enter.

From Wikipedia: https://en.wikipedia.org/wiki/Aspect_ratio_(image)

With television, DVD and Blu-ray Disc, converting formats of unequal ratios is achieved by enlarging the original image to fill the receiving format's display area and cutting off any excess picture information (zooming and cropping), by adding horizontal mattes (letterboxing) or vertical mattes (pillarboxing) to retain the original format's aspect ratio, by stretching (hence distorting) the image to fill the receiving format's ratio, or by scaling by different factors in both directions, possibly scaling by a different factor in the center and at the edges (as in Wide Zoom mode).

Your problem at hand is your source material being 16:10 (or 1.6:1) computer screen, and your output is 16:9 (or 1.777..:1), which naturally leads to letterboxing or pillarboxing, for Both of which there isn't (yet) a dedicated simple tool to fix as TrackFX. The only solution is to create a Pan/Zoom EventFX with the numbers to suit your needs, and Selectively Copy that FX to all other affected clips
