ok but maybe the dont zoom option is only meant for the 4k girls...

No, that is exactly the wrong conclusion. The "Don't zoom over 100%" is is meant to apply to the lower resolution cards - those are the ones that ***** most from being enlarged to fit the screen. Unless you have a screen with a higher resolution than 4k any 4k clips will need to be reduced in size to fit so restricting the zoom to be no higher than 100% can have no effect on them (unless you deliberately configure things to concentrate the girls legs by setting the size slider to well over 100%).

Ticking it optimises for video quality but in order to do this you have to sacrifice equalising the heights unless you want to equalise to a low height. A 480p image has only 1/9th of the pixels than one that is 1440 pixels high (only 1/16th of those of a 4k image) and even less information than that when you take the colour depth into account. If you try to blow up a low resolution image you will inevitably end up with a poorer quality result than that you would have starting from a higher resolution.

If you want the girls to have roughly the same size then untick the option and adjust the size slider - you should get the result shown by @Dorsai6 's second post. Or you could tick the option an reduce the size until the highest resolution clips have the same height as the lowest resolution clips - then all the girls should appear to be equally short.

However, if you want the best video quality then tick the option. The 480p and 720p clips will still have lower quality but not as poor as it would be if you try to enlarge them over their natural size. This is because they were recorded years ago with lower resolution cameras - good resolution for the time but poor now. (Actually if you just want the absolute best video quality then tick the option and set the size slider to be well over 100%, the clips will then be displayed at their natural resolutions but those that have a higher resolution than your screen will be much taller than the screen so you probably will not want to do this)

when it was unchecked the girls were too tall to me

Then use the size slider to reduce them to a size that suits you - that is what that control is there for.

guys i tried unchecking the dont zoom option and i played a 720p card...comon guys cant you see it looked terrible

Yes - that is what we have been telling you. You can optimise for video quality or for equalising the heights but not for both at the same time. Even if you optimise for quality the high resolution clips will look better because they have inherently higher video quality anyway. You can't put in details that were not recorded when the clips were shot - in the case of 480p they were originally recorded on video tape.

Now, it does seem that Totem use a very simple - but efficient - algorithm to to rescale the videos. They could use a better one which would improve matters somewhat, though there would still be a very visible difference in quality, but this would be at the cost of higher CPU usage which in turn could cause the playback to stutter, jerk or be slow.

On the size slider the percentage is relative to your screen height - irrespective of the clip's resolution.

However, the 100% on the "Do not zoom over" control is relative to the clips own "native" height.

Setting the size slider to 100% with the "do not zoom over 100%" unchecked should scale all the girls when standing to have similar heights and fit the screen's height. But as the table clips are deliberately intended to mimic a closer view, as if you had moved to the edge of the stage, the girls will look bigger in these than in the standing clips - they are sized to better fit the width of the screen rather than its height.

There is, unfortunately, no way to change this in desktop mode - in fullscreen scenes you can control the standing and sitting sizes separately but you can't for the desktop.

Let me give you a simple, simplified, example. In reality it is a little more complicated, but this is roughly what happens.

If you have a 4k screen then with the option unchecked all standing clips should be of a similar height and all table clips should make the girls look larger than when they are standing. If you tick the option then 4k clips will still fit the height but lower resolution clips will look smaller.

If you have an 8k screen then with the option unchecked a size setting of 100% should once more make all standing clips fill the height of the screen, but enabling the option would halve the height of a 4k clip and more than halve the height of lower reolution clips.

If like me you have a 1920x1080 screen then with the option unchecked setting the size slider to 100% will display all standing clips such that they fit the screen's height, enabling the option will leave 4k, 3k and 1080p clips fitting the height, 720p clips will reach about two thirds of the way up the screen and 480p clips less than half way.

Ths is untested as I do not have a 4k let alone an 8k screen, but that is how it works on my 1960x1080 and 1600x900 screens.

If you uncheck "Don't zoom over 100% of the clips' original size" then the sliders controling the small size and large size will affect all cards equally, if you have it ticked then this is not the case as it will then limit the magnification applied to lower resolution clips well before it has any effect on higher resolution clips.

@Wyldanimal has previously posted a detailed explanation of all this, together with its limitations, however I can't find it at the moment.

Very roughly, because I do not know all the details, if the "Don't zoom over 100%" is not ticked and the size slider is set to 100% then, for standing and pole clips, when the model raises her arms above her head they should roughly reach the top of the screen. For high 1080p (or higher) resolution clips displayed on a 1080p screen this will not entail any magnification of the clip by the software but for 720p and 480p clips magnification, and hence loss of image quality, will be required. Enabling "Don't zoom over 100%" disables this magnification in order to preserve image quality.

In practice because of differences between how the clips were framed when they were shot and processed this does not work perfectly.

Note, the rules for table clips are slightly different as they are intended to be "close up" views and the models will appear to be larger than in the standing clips. Sometimes, though only sometimes, I wish that there was an option to eliminate this difference so that both types of clip match my desktop's background image.
