It's interesting to see how tiny Netflix mobile download files are.
200MB - 300MB for full-length movies, ~150MB for series episodes.
This is on "Standard quality", but still.
After some quick Googling (grain of salt) I see that a standard DVD of 4.7GB tends go have (usual encoding) up to 135 min of 480p video. That's a big difference! Even when considering that modern encoding might be more efficient. It is lossy compression, and the lossyness seems to be cranked way up.
- botanical 3y agoDVD's definitely didn't use up the entire 4.7GB. A movie was anything from 700MB to 1GB
- wodenokoto 3y agoI remember old dvd players had a noticeable pause in the movie when it changed layers.
- Sohcahtoa82 3y agoYup. The movie producers would try to hide it by placing the layer change in a scene change, but I often still noticed it.
- phonon 3y agoI think you're confusing them with MPEG-4 rips that are burned on DVD-R.
- antiloper 3y agoYes, DVDs use the MPEG-2 codec which has a horrible compression ratio compared to H.264 (and CD audio is completely uncompressed).
- SirMaster 3y agoCommercial DVD movies were bigger than this. They used dual-layer DVDs and the main movie was often 6-7GB.
- parsimo2010 3y agoDVDs of movies were actually dual layer, and had ~9GB capacity. I remember this distinctly because to copy a movie rental to a DVD-R you had to use a program like DVD Shrink so you could strip out all the extra features and compress the video a bit more to get it to be under 4.7GB
- zamadatix 3y agoThis will depend on the movie and dual layer was more an exception than the norm. Rarely, a movie could be spread across multiple discs as well. Most typically for the extras but sometimes just to fit longer movies in decent quality.
