Stretch and Fast Video WHAT?

Hi all:

I've working with saving my movie to a file format (in Make Movie).
I've tried both "Stretch video to fill output frame" and "Fast video resizing" but
do not see any difference in the output.

I Make the Movie without Stretch and then run in the Standard Windows media player.
I then Make the Movie with Stretch enabled and run it in the media player.
I then Make Movie with Fast Video Resizing and run in media player.

I notice no difference between any of these options in Make Movie.

I've read the help in VideoFactory but am still not clear I guess.

Can anyone shed some detailed light on Stretch and Fast and what they do and why
I'd use them?

Thanks everyone.

-Mike

Hmmmmmm......

Both these procedures don't produce "Fast & Slow" motion - I wasn't thinking for one moment you were thinking that this is what would happen.... were you? Nah can't be! But, but if you were you'd be forgiven. Ah go on tell us that is what you thought! ... Cos I did!

The only clue was your "Can anyone shed some detailed light on Stretch and Fast and what they do and why I'd use them?"

However, if you were thinking of trying to make slomo or fassssstttt forward you need to do something different. I/we will tell you if you would "suggest" what you were expecting to happen....

I've been there - best regards,

Grazie

Stretch- if your video is not the correct aspect, VF will stretch or shrink it to fill the frame.

Fast- Fast speeds up rendering while creating an AVI. As the warning states, it can introduce artifacts that may or may not affect the quality.

Thanks Dave and Grazie

Sorry I did not make this clearer.

I'm refering to the meanings behind both
Stretch video to fill output frame.
and
Fast Video Resizing.

I'm rendering to 720x?...

For Stretch video...
I was expecting something like the image being made larger when played in the
media player.
For Fast Video resizing...
I was expecting to see some odd/poorer quality in the video when played in the
media player.

Since I see no difference I'm thinking about rendering without either of these
options.

My videos are intended to be viewed on a normal television screen via a standard VCR (so our videos can be shared among family members) so I am campturing some family movies, editing them and then sending the edited video out to a VCR via a Dazzle Hollywood Bridge (NTSC_DV).

I'm trying to determine what the best template to use is so that the videos will look as good as possible.

Thanks

simmerheli;

I haven't fooled around with the "Stretch Video" option, but I do routinely turn the "Fast Video Resizing" off.

In my own experience, I can see a significant improvement in the image quality, particularly when viewing on a 30" or larger TV.

The only downside seems to be longer rendering times, but that's OK, because I usually hit the "Make Movie" button and go to bed anyway.

Normally video is a rectangle with approximately the proportions 4 (wide) by 3 (high). Sometimes you'll come across clips or stills that are not this shape. When you use these in yor project, Video Factory will shrink them to fit and there will be black areas left over either above and below, or on the left and right sides. Stretch to fit will stretch these cilps and stills out so that they fill the entire 4x3 rectangle without any black space left over.

Most of the time, the only times you will encounter these odd sizes will be with "vertical" stills, pictures that are taller than they are wide. In these cases, stretching the picture out to fill the frame is probably NOT what you would want to do anyway as it will make your subjects look very short and fat ;) If you do have pictures of this sort that you want to fill the frame then use the Pan & Crop tool to zoom in on a smaller section of the photograph.
