Workshop 8 - Compression

The 8th workshop covered compression, specifically the compression of videos for additional use, whether you need to upload it somewhere or give it to someone that has a file size limit.

The two main things to consider are the file format of the video and the video format of the video, the file format is a container while the video format is actually how the video is compressed. Where the file format deals with a user’s output functions i.e. what player are they using? The video format deals more so with the video quality itself, although it may at times be a factor for certain players too.

There are a few reasons for the compressing of videos. As previously mentioned, one reason is that a lot of uses for the video will require a low file size due to file size limitations. The other important consideration for compression is the compatibility, this is to say that not every user/viewer has a player that will be able to play every file type or video type.

Workshop 8 - Compression (1 Mbps compression)

Lossy; Quicktime Photo JPEG (3/10)

Lastly, Photo JPEG; the least favourable. Honestly, with today’s standard for videos you would never really make use of this kind of compression, unless your purpose was for an actual bad quality video. This format is also known for producing JPEG artefacts on the video itself, which is problematic.

Workshop 8 -  Compression (3 Mbps compression)

Lossy; Quicktime H.264  (5/10)

The next lossy compression method is the H.264, still a reasonable quality for most cases. Although not the best in terms of render time and file size in comparison with other formats, in regard of the quality it will do the job.

Workshop 8 - Compression (5 Mbps compression)

Lossy; Quicktime Prores HQ (7/10)

Prores HQ, arguably the best lossy compression file format as the quality of the video seems almost lossless. Again, given the file format’s render time, file size, and overall quality; a clear choice. The render time was in the top 3 formats, however it didn’t have the best file size, but in the perspective of lossy file types and it’s actual quality it’s still a good choice.

Workshop 8 - Compression (full quality)

Lossless; Quicktime TIFF LZW (10/10)

For the lossless compression I have deemed the ‘Quicktime TIFF LZW’ the most efficient file format due to a number of factors. Considerations included render time, file size, and video quality. Though the render time was 3-4 minutes longer than some other favourable options, the overall file size and quality far out weigh the additional wait.
