What is the Lossless Video Size Reduction tutorial about?

The video tutorial Reducing the size of video files without loss is about how we can reduce the size of a video file without losing quality.

Why reduce the size of video files?

How good it would be to be able to reduce the physical size of objects.

It would solve the problem of parking spaces and storage places in homes.

If in reality you can not reduce the size of objects, in the digital world the size of files can be reduced by compression.

You can reduce the size of video files that you've gathered over the years to take up less disk space.

Compress or compress video files

Using a modern codec, such as H265, also called HEVC, we can greatly reduce the size of video files.

This can be achieved thanks to the algorithm used in the H264 codec, which compresses video frames much more efficiently.

Compression and implicitly size reduction is essential for video streaming services such as YouTube, TikTok, Netflix, HBO, Facebook, etc. They can suffocate in traffic, without a codec that makes video files as "thin" as possible.

How come there are no quality losses?

Due to the efficient compression mode and the way this codec works, the video files transcoded with the H265 codec do not show quality losses.

There are losses, but they are not visible.

We also have two disadvantages, which will not affect too many people

  • Resource consumption slightly higher at H265 than at H264
  • Editing will be more difficult due to complex compression

The phones have the option of shooting in H265 in the camera settings

Take a look at the camera settings in the video settings section and you will find the option to shoot with the “Efficient” codec “HEVC” or “H264”.

Thus, using the H264 shooting option, the footage will be smaller without visible quality loss.

What software can transcode video files into H264 to reduce their size?

HandBrake is the natural option, because it is free and offers multiple options.

    Interesting. I tested on a 1,26GB video file. It has been compressed to 86,4 MB.
    Input parameters: 1.26 GB .mp4
    04:34 duration
    2288 × 1080 pixels
    60 fps
    191 kbps

    Output parameters: 86.4 MB .m4v
    04:34 duration
    1920 × 1080 pixels
    30 fps
    160 kbps

    The funny part is that if you try to open the .m4v file with the Movies & TV application from Win10 it tells you that you need HEVC Video Extensions and it costs 4,99 lei.

    • You can open it with HPC-HC or VLC. I tried and it opens without asking for HEVC.
      What's worse is that I tried to edit the video and it closes my editing program.
      Indeed, a 440 MB file made it 39,2 MB, the quality was not lost, but what good is it if it can't be edited.
      Respectfully, Dan Ș.

  3. Mr. Cristi, please answer me, if you can and you know.
    I proceeded exactly as in the video tutorial, it compressed a video file, from 440 MB to 39,2 MB, so far it's super Ok, but when I insert it in the video editing program, respectively Power Director, it closes the program.
    I mention that the filming is from an event, has 1,17 minutes and is very large, I told you at the beginning, 440 MB. All shooting is 64 GB with a single camera. The event was filmed with 3 cameras, and I have to synchronize them during editing, the total filming being 100 GB.
    That's why I wanted to reduce the size so as not to consume my PC resources.
    So the question is, why does the video editing program close when the transcoded file is implemented? Respectfully, Dan Ș.

    • Mr. Cristi, I struggled a bit and I managed something.
      When saving, where the location has to be passed, the file is saved with the m4v extension, I gave it to save it with the mkv extension, it lost a bit of quality but I am going to implement it in the editing program.
      If you have anything else to add, I look forward to hearing from you.
      Respectfully,
      Dan Ş.

  5. I did not manage in any way to reduce the size of the transcoded file.
    I'm missing something but I don't know what.
