Tommi 🤯<p>So I have hundreds of videos of ~1 minute recorded from my phone ~10 years ago, and they generally don’t have that great compression, nor they are stored in a modern and advanced video format.</p><p>For archiving purposes, I want to take advantage of my workstation’s mighty GPU to process them so that the <strong>quality is approximately the same</strong>, but the <strong>file size would be strongly reduced</strong>.</p><p>Nevertheless, compressing videos is terribly hard, and way more complex than compressing pictures, so I wouldn’t really know how to do this, what format to use, what codec, what bitrate, what parameters to keep an eye on, etc.</p><p>I don’t care if the compression takes a lot of time, I just want <strong>smaller but good looking videos</strong>.</p><p>Any tips? (Links to guides and tutorials are ok too)</p><p>Also, unfortunately I am forced to use Windows for this (don’t ask me why 🫠), but I know nothing about Windows because I hate it. Practical software suggestions are very much welcome, too!</p><p><a href="https://pan.rent/tags/ffmpeg" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ffmpeg</span></a> <a href="https://pan.rent/tags/help" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>help</span></a> <a href="https://pan.rent/tags/askFedi" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>askFedi</span></a> <a href="https://pan.rent/tags/codec" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>codec</span></a> <a href="https://pan.rent/tags/AVI" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AVI</span></a> <a href="https://pan.rent/tags/H265" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>H265</span></a> <a href="https://pan.rent/tags/H264" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>H264</span></a> <a href="https://pan.rent/tags/movie" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>movie</span></a> <a href="https://pan.rent/tags/video" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>video</span></a> <a href="https://pan.rent/tags/videoCompression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>videoCompression</span></a> <a href="https://pan.rent/tags/compression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>compression</span></a> <a href="https://pan.rent/tags/encoding" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>encoding</span></a> <a href="https://pan.rent/tags/HandBrake" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>HandBrake</span></a> <a href="https://pan.rent/tags/heif" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>heif</span></a> <a href="https://pan.rent/tags/heic" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>heic</span></a> <a href="https://pan.rent/tags/avif" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>avif</span></a> <a href="https://pan.rent/tags/mp4" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>mp4</span></a> <a href="https://pan.rent/tags/mkv" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>mkv</span></a> <a href="https://pan.rent/tags/Wondows" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Wondows</span></a></p>

Let's turn some <code>bz2</code> files into <code>bz3</code> to see the difference.</p><p><strong>First example: 90k opus files</strong></p><p>hey snips wake word dataset. It has ~90k opus files and a tar file of <code>3.1GB</code>. <code>bzip2</code> produces the same <code>3.1GB</code> which is as expected. bzip3 created <code>3.0GB</code> but used tons of computation power. Not worth the <code>100MB</code></p><p><strong>Second example: Windows 7 virtual box VM image</strong></p><p><code>Windows7.vdi</code> it's Windows 7 VM image for the "special" days. I think I have to get rid of it. But while it is still there, let's see how each will perform. It is <code>16GB</code> uncompressed. <code>bzip2 -9</code> is <code>7.0GB</code>. <code>bzip3</code> is <code>6.3GB</code> but at the expense of like 3x CPU time. Deleting all of them anyway. Down with Windows.</p><p><strong>Third example: Pure XML text file</strong></p><p>Pure XML file. It's Persian and English characters. Uncompressed is <code>1.7GB</code>. <code>bzip2 -9</code> is <code>276M</code> while <code>bzip3</code> is <code>260MB</code></p><p><strong>Final example: Creating a simple bomb</strong></p><p>So I did this:</p><pre><code>dd if=/dev/zero of=./justzero bs=2G count=6<br></code></pre><p>So now I have a <code>16GB</code> with only zero bytes. <code>bzip2 -9</code> is <code>672KB</code>. <code>bzip3</code> is <code>46KB</code>. </p><p><strong>Conclusion</strong></p><p>Thank you <span class="h-card" translate="no"><a href="https://polymaths.social/@rl_dane" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>rl_dane</span></a></span> </p><p>Real nice thing!</p><p><a href="https://cr8r.gg/tags/compression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>compression</span></a> <a href="https://cr8r.gg/tags/gzip" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gzip</span></a> <a href="https://cr8r.gg/tags/zip" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>zip</span></a> <a href="https://cr8r.gg/tags/filecompression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>filecompression</span></a> <a href="https://cr8r.gg/tags/textcompression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>textcompression</span></a> <a href="https://cr8r.gg/tags/datacompression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>datacompression</span></a> <a href="https://cr8r.gg/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linux</span></a> <a href="https://cr8r.gg/tags/unix" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>unix</span></a> <a href="https://cr8r.gg/tags/tech" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tech</span></a></p>
Farooq | فاروق<p>So I was short on storage on my archive drive. I saw librewolf source code. It was <code>tar.gz</code> and ~800MB. I uncompressed it then recompressed it with <code>bzip2 -9</code> and now it's ~600MB. Generally <a href="https://cr8r.gg/tags/bzip2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bzip2</span></a> has better compression for such these data than <a href="https://cr8r.gg/tags/gzip" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gzip</span></a>.</p><p>Edit: But don't do <code>bzip2 -9</code> all and everywhere.

The use of ambiguity in AI responses because it doesn't know what to put. In effect the reader sees the meaning in the sentence.</p><p>Does this mean that we are being gaslighted, and AI is not nearly as advanced as we think? Has it just learnt to produce text that is plausible to anyone and fits multiple interpretations, just like the tabloid astrology columns?</p><p>I don't think there's a simple answer to this. On relatively closed domains like writing computer language it definitely can produce real direct answers. On ambiguous social questions, perhaps it does produce ambiguous answers for us to project meaning on to?</p><p>I'm quite surprised that I hadn't noticed or thought of this possibility.
