Most modern cinema cameras shoot in very large resolutions (4K, 6K, 8K, 12K etc.) and in RAW uncompressed file formats. In video post-production there are numerous stages of the process that usually require some transcoding. Here the former is higher quality in comparison to the latter but has a larger file size. Apple ProRes often does a great job in this regard and it can be difficult to visually distinguish between, for example, ProRes 422 and ProRes LT. ![]() It is worth mentioning that there are also some smart codecs that are ‘visually lossless’, which is to say that you can’t tell by looking at them whether they are the original or the transcoded version. But, on the other hand, yes transcoding reduces quality, but usually this is the intention because you’re throwing away some of the data in order to reduce the file size or serve another purpose.There is no ‘generational’ loss between the copies if you don’t intend to introduce one. In some senses, no transcoding doesn’t reduce quality, in the way that taking a photocopy of something might do - especially if you take a photocopy of a photocopy.It all depends on how you do it and why you’re doing it. Let’s take a look at some common video transcoding workflows and some of the important considerations for each.īut before we do, one question we need to consider is: Does transcoding reduce quality? Or, the high-resolution makes adding effects and filters bog down the system to another stand still. Even the fastest hard drive would struggle to deliver data quickly enough from the drive to the computer without skipping or dropping frames, leading to stuttering playback. The file sizes are often too large for anything. Any editor who has worked with high-quality, computationally-intense and storage-hogging video files knows that this doesn’t make for a smooth or efficient video editing experience. Transcoding the video files in this way ensures the best possible experience for the end user at the time. These might include Blu-Ray MPEG files, H.264 mp4’s for online streaming and many more. ![]()
