How to compress video captured by SnagIt and other programs
Friends, I would like to share with you my little experience in compressing video files. Namely, to reduce the size of the source file.
A few days ago, using the SnagIt program, I recorded several training videos on translating a static site to the ExpressionEngine engine . This, again, is my first experience in recording training videos. The files turned out to be large, take at least a file lasting 1 minute 18 seconds - it was 87 MB in size.
Of course, such a file size is not acceptable for such an amount of time, so we need to compress it. I would also like to note that I recorded on the screen on an arbitrary portion of the screen, so the dimensions of the video will not be standard.
We need:
A set of K-Lite codecs, (we need the DivX and Xvid codecs in it)
VirtualDub program (the latest version can always be downloaded from here )
1. Open the file in VirtualDub
2. Go to the Video - Filters menu (Ctrl + F). Click the Add button and add a resize filter.
Next we go to its settings and specify the compression percentage, or the specific size of the output image.
Next, the article is divided into two parts
3a. Click Video - Compression (Ctrl + P). Select the DivX codec, click Configure and configure.
I chose the best quality and set Multipass, 1st pass in Rate Control Mode . I will compress the video in two passes. This is the first. 4a. Click File - Save as AVI (or the F7 button) and save it under some name. After saving, do not close the VirtualDub window. We go again to the codec settings and select Multipass, Nst pass in the item Rate Control Mode . This is the second pass.
3b. Click Video - Compression (Ctrl + P). Select the Xvid codec, click Configure and configure.
I chose Highdef quality and set Encoding Type to Twopass, 1st pass . I will compress the video in two passes. This is the first.
4b. Click File - Save as AVI (or the F7 button) and save it under some name. After saving, do not close the VirtualDub window. We go again to the codec settings and in the item Encoding Type select Multipass, 2nd pass . This is the second pass.
5. Save the file File - Save as AVI(or the F7 button) but under a different name, this will be our source file.
As you can see, the size of the output file has decreased significantly. Its quality can be varied by settings, experiment.
I think the article will be useful for beginners, there are no special difficulties. I noticed that using the Xvid codec loads the system less and at the output I got a pretty high-quality file with a good image and with the same sound as it was before. Try it, good luck.
