Does anyone of a software that can resize input video without compressing the original video?
I am looking for a software that can take a high resolution video (MPEG-2) and scale it down to 640 x 360 MPEG-2 (no compression) for the output. I would greatly appreciate if someone provides me information
Yes, the playback-downscaling will work, but that won't alter the size of the original video. Secondly, I was looking for a lossless encoder which can simple transcode the original video (without any compression). All I want is something that can scale down the spatial resolution of the original to 640 x 360.

If you change size, you must recompress the video. You can choose a lossless or a high-quality codec to preserve the video quality.
Your only alternative would be to just use a player that scales the video on playback, but it doesn't alter the original file at all.

Compression is substantial as audio, video and photograph records oftentimes take in a huge volume of area for storing while in comparison with different records varieties. Compression reduces the form of bits in entire required to characterize the comparable suggestions. This will enhance flow velocity and helps extra records to be saved in a similar area. Compression is finished by way of way of a CODEC (compression-decompression), that's an set of rules used by way of an utility to save and open a document. the two the utility beginning up the document and the utility encoding the document could own the codec.
