If the frame rate of the video isn't carefully managed and aligned with the output of the transcription tool, it can create errors or problems with synchronization. Ensuring a clean and accurate output is key in many professional situations.
The way different codecs affect the CPU is something to consider. Encoding or decoding a video with a newer codec like VVC can place a heavy load on the system compared to older ones like some MPEG formats. This can cause a significant drop in performance if the machine doesn't have the resources to handle the workload. This is something that needs careful monitoring, especially when working with large or complex projects.
Metadata, the information that is stored alongside the video, can have a surprising impact on file size. If the metadata is excessive or not managed carefully, it can add unnecessary weight to the file. This often gets overlooked but is a key aspect of optimizing storage space and workflow.
Some of the AI-based transcription tools offer real-time transcription, which is quite powerful. This means users can receive the text output at the same time they are playing the video. This has the potential to drastically change workflow speeds by removing a large portion of the delay between viewing and receiving text output.
Conversion times aren't always predictable, and it depends on a wide range of variables, but one of the most important is the complexity of the video file. Videos with complex editing, grading, or effects are going to take a lot longer to convert than simpler files, which is something to keep in mind when planning a project.
The nature of compression means that you'll introduce artifacts, or visual errors, in video during the conversion process. The type and severity of those will depend on the chosen codec and settings. It's worth taking the time to familiarize yourself with the artifacts different codecs are likely to produce to make sure the final outcome fits the goals of the project.
When you're constantly editing or converting a file, it can get fragmented. This isn't always visible to the user, but it can lead to a slowdown in performance over time. This makes it useful to archive the final version occasionally or re-encode it. It's a good reminder that a simple edit can have unexpected effects over time.
