I have a video file which I would like to apply some effects and filters to and save it exactly with the same format parameters without recompression. Can this be done with your software?
Practically, it is impossible to save the actual FILE after applying changes to it without recompression. However, AVS Video Editor provides features which will let you totally avoid recompression necessity and quality loss during the process of editing.
The ideology of AVS Video Editor is built around working with projects rather than with particular video files. Working with a project allows you to save the sequence of changes in the file settings and all the applied effects and only need to save the file when you absolutely complete the editing.
To save the project in which you are editing a particular video file, do the following:

Select Project in the File menue and pick one of the saving options, instead of selecting Save Movie File.
Note! If you select Save Movie File option, your video will be recompressed while saving. If you saved a project instead, next time you open it and go to Edit Video menu, all the changes that you have applied to your video file during the previous editing session will be reflected on the timeline:

Can I transform 4:3 files to 16:9 files and visa versa with the help of this software?
Yes, you can. Starting with version 3.2 AVS Video Editor supports aspect correction. Just follow the steps:
- Start a new project. Select the necessary aspect - 4:3 or 16:9;
- Import a video file you would like to transform. Place it to the working area.
- Click the right mouse button to open the video file properties window, select Aspect, and use Crop to get rid of the mattes (black bars) on top-bottom or on the sides of the video.
- Save video into necessary format. You will be offered to use aspect correction, so that your output movie could be displayed without distortions.
The output movie will have a new aspect ratio.
Note: when using the Crop function, parts of the movie picture will be deleted together with the mattes to maintain the selected aspect ratio. If you do not want to lose any part of the movie picture, please leave the black bars untouched.
What is aspect ratio feature and how is it different from video resolution?
Video resolution is a constant measure which describes the width and the height of a video file in pixels.
Easiest way to explain aspect ratio is to say that it means the ratio between the width of the picture and the height of the picture. Normal TV's aspect ratio is 4:3 (1.33:1) - Academy Stanndart, NTSC Television.
When it came time for the television industry to decide what shape TV would take (in the early 1950s), the US National Television Standards Committee (NTSC) selected Academy Standard as the official aspect ratio for TV broadcasting in the United States (the current TV standard in the U.S. is also called NTSC, after the organization that set the standard). Up to the 50s all video production was made with this aspect ratio.
After the 50s film industry was faced with a problem: so many people were buying TVs and staying at home to watch them, that theater attendance began to decline dramatically, which lead to the appearance of wide screen aspect ratio.
There are two "standardized" widescreen ratios that are by far the most common: Academy Flat (HDTV's) 16:9 - (1.85:1) and Anamorphic Scope (2.35:1). Other less used ratios include 1.66:1 and 2.20:1 So, as you can see, aspect ratio is in fact a relative measure. When it comes to file format, Aspect ratio is defined for all formats, except AVI, so in case with conversion to AVI to avoid vertical or horizontal deformation of the picture it is better to set up resolution which correllates to a particular aspect ratio. Here's a small table, which correlates most common AVI video resolutions with aspect ratios:
| 4:3 |
640 x 480 |
| 16:9 |
640 x 360 |
| 2.20:1 |
640 x 292 |
| 2.35:1 |
640 x 272 |
