Introduction

• Increase resolution of your video with Video Super Resolution technique which delivers unbelievable quality by using information from previous frames, while all the other resize methods use information from one current frame. Now you can convert your SD video to HD!
• Use hundred of VirtualDub filters allowing you to do everything you want with your video.
• Open any video which can be played on your system and re-compress it with any video codec (DirectShow, DMO and Video for Windows) installed in your system.

When processing what Video Enhancer does in general is the following: it opens the input file, finds a suitable decompressor installed in your system, decompresses video, applies Super Resolution and/or filters you chose (see below) then compresses video using chosen codec and stores it to an AVI file you specified for output. If the input file contains audio stream, this stream is recompressed with chosen audio codec or copied to the output AVI file without changes.

In the Simple mode (opens by default when you start Video Enhancer for the first time) you can easily use Super Resolution technique to increase your video resolution. Just choose new width and height and how you want SR to do it: slowly and accurate or faster and less accurate.

There are actually two image sizes that Video Enhancer uses to resize your video - output width and height and actual image size to scale to. Suppose you have a video 320x240 and want to make it 720x480 (NTSC). If you just scale 320x240 to 720x480, the image will become wider, all circles will become ellipses and all people will become fat. In order to preserve aspect ratio and make video 480 lines high, output size must be 640x480. But you wanted 720x480! In this case you just set output size to 720x480 and size for scaling to 640x480. Video Enhancer will scale your video to 640x480 and add black borders to right and left to make output width 720. Or, you can set scale size to 720x540 and output size 720x480. Then Video Enhancer will scale your image to 720x540 and keep 480 center lines, cutting top and bottom. Of course, if you want to change aspect ratio (to make fat people look less fat, for example) you can set any values of width and height.

In the Simple mode you enter just one size - output size. Video Enhancer preserves aspect ratio and scales your video to fit output size (no cutting) adding black borders if needed. In the Advanced mode you can set both sizes manually.

Parameters:

• -i infile - specify input file. Use double quotes (like "...") for filenames that include spaces.
• -o outfile - specify output file,
• -d width height - destination video size,
• -vc codec - set name for video codec. First codec which name includes substring you specify here will be used. So you don't need to specify full name of the codec. If this parameter is not set, uncompressed RGB32 video will be stored (huge size)!
• -ac codec - set name for audio codec. If this parameter is not set audio will be copied without recompression.
• -vlist - output list of video codecs that can be used. All output is written to text file ve.txt in same folder as VideoEnhancer.exe.
• -alist - output list of audio codecs.
• -fast - use fast mode of super-resolution. If this parameter is not set, a slower high quality mode will be used by default.
• -nomt - do not use multithreaded processing.

Examples:
Show all available codecs:

VideoEnhancer.exe -vlist -alist

Upsize a file to 640x480 and compress result with Huffyuv codec:

VideoEnhancer.exe -i 176.avi -o "Upsized 176.avi" -d 640 480 -vc Huff -fast
