Reduce filesize on videos without losing quality

[VexatiousCheff]

I made a video in a game titled geometry dash and i wanted to reduce filesize on it somehow.

Original filesize: 41,114 kb
New filesize: 16,119 kb

Before you ask "Does this result in any loss of quality?"
No, no it doesn't

Spoiler: First frame from original video

Spoiler: First frame from output

Then getting the difference of the two images results in this:

Spoiler: Difference (difference is highlighted in red)

As you can clearly see there is no difference whatsoever

So how did I do it?

First time you do this:
1. Install FFMPEG if you haven't already

Every time you do this:
1. Open CMD
2. CD to your video path (e.g "cd C:\Users\{PC_USERNAME}\Videos")
3. Type ffmpeg -i "{VIDEO_NAME}" "{VIDEO_NAME2}"
4. Press enter
5. Now wait as FFMPEG output's the video

Spoiler: Commands I typed

Easy as that!

Heres the difference for a 500mb replay:

This is good for people like me who's internet especially isn't great.

Spoiler: Tool I made to convert every video in a folder

Download
Source code

How to use it:
1. Download the EXE and put it in the folder with all your videos
2. Run it
3. Type "y" if you want it to delete every file after it has formatted it

Done!

Spoiler: Results from someone who has 1tb of videos

Spoiler: Before

Spoiler: After

just download more internet

or you could just use handbrake, or even adobe's media encoder

youtube will compress your video anyways

isnt about youtube compressing videos

first point still stands + most modern video hosts will compress your file

isnt about "modern video hosts" compressing videos buddy

first point still stands + the hell are you doing with the video then

Yeah I can vouch for this I used to use handbrake when I had shit net, file size down 90%+ with no quality loss, sometimes it actually looked better than the uncompressed version once uploaded because youtube is less harsh on smaller files I suppose

if u wanna use adobes media encoder then use it, same with handbrake, i rather use ffmpeg as i figured it out in two minutes

Hes talking about file size to make uploads faster

Thanks for the tutorial, Vexy

yes, hence "uploading to a modern video host"

 

[tobby]

handbrake is better imo

What's your download?

 

[DebilniCheater]

not good for clips, since yall all pixalated hahaha

The first frame of a video may look fine but, with video compression bitrate is changed and that is a huge factor in video quality. Just thought I would mention that.

 

[deniiissska]

now there are a lot of all sorts of codecs for video compression, but unfortunately not one of them makes the quality the same cool after living like the original

why would u think u can reduce the video size without losing the quality lol

a file size of a video is affected by the resolution, length, frame rate etc so reducing the file size u have to choose one to "optimize"

the only way could probably do that is lossless compression (note that not all video format support this compression) and theoretically u can't reduce the size a lot lol
