Hello, my name is Pjotr. I'm 27 years of age.

 

I do have movies on my hard disk of my computer.

Here's my interest:
I have WinRAR installed. I have tried to compress the large video files by that, and nothing in return. The large video files do remain of an equal big size, and the WinRAR compression program doesn't seem to do much about it.

Question: what are the software available, that is designed / made for especially for compressing large video files (like movies)? Is there any?

 

PLEASE, POST YOUR LINKS!

 

 

Thank you. :)
...happy new 2015 year! Celebrate!

 

P.S. I also have an mp3s folder.

 

Also:

In WinRAR 5.20 I've noticed a "rar5" compression method. What is it?

I don't know if you're still looking for a powerful archiving tool rhino, but whenever this question was asked on other forums I was on, a lot of people would recommend KGB Archiver as the most powerful archiving program there is. Apparently, it's discontinued and not updated anymore, people some people think that it's still better than WinRAR, 7Zip, WinZip, etc. in term of compression size. Maybe it's worth giving it a try and see how it goes?

Also, here's a complete guide written by RARLab (the developpers of WinRAR) about the new RAR5 compression method :)

Most video file formats are inherently compressed, and you will not be able to compress them further without degrading the quality.

In my experiences LZMA2 has the best luck with hard to compress files, as that's what it was built in mind for. If you use a non-indexing archive format like XZ instead of say ZIP that will also aid compression, but XZ only supports 1 file per archive. Many video codecs have built in compression, therefore the only way to yeild further compression would be if the archive's compression algorithm is more efficient than the video codec's was. Long story short, putting videos into compressed archives is pointless because the data is already compressed. You might save a few % of space, but I wouldn't expect any worth-while results regardless of what program you choose to use. This is why people tend to convert their videos to smaller degraded copies, thereby sacrifcing quality for space savings. Codecs like H.264 are good for going that route.

HandBrake is a popular free one, and it supports creating a que of conversion jobs. Sometimes I'll setup a que of a bunch of files I want to convert, and then just leave my computer on overnight.

I definitely agree with HandBrake. Very good conversion/compression program, it just keep on growing on popularity.

Not sure what you mean. H.264 is H.264 regardless of what program you use to encode it with. I'm looking forward to H.265 which is offers even better results.

H.265 is already out, but last time I checked there weren't any programs offering it yet. It appears things have changed since then, because the HandBrake now has support for it according to ( https://trac.handbrake.fr/wiki/Encoders ). I'm still using the HandBrake 0.9.9 currently (which was before H.265 support was added).

What's on percents? ...the win of H.265 over H.264 by compressions. :)   Have you already checked this?

So, on the Internet, converting and compressing videos is somewhat the same business? H.264 codec.

 

To harder compress already good sized *.mp4 videos is a job for a video converter, as I see? Freemake can do this task?

 

 

Can you provide me with a chart of proper conversions/compressions, from-to? :)
