Tips for getting the best results
Most programs provide a pretty straightforward process for converting files. Additionally, there are a few smart steps that can help you get the best possible output. They would be especially helpful if you’re dealing with older or lower-quality video sources.
Choose the right output format
If you want to achieve the best compatibility across devices, platforms, and media players, your best bet would be MP4. Moreover, content creators might have the need to edit files later. In such a case, it would be smarter to choose formats like MOV or AVI. That would depend on the software you use for editing.
Adjust the resolution and bitrate
More often than not, some FLV files have low resolutions. If later you want to show your video project on a big screen, you should consider upscaling slightly or adjusting bitrate settings to reduce pixelation. There’s no need to install another software, as you can opt for Movavi or Vidmore since they offer this feature.
Trim or edit unnecessary parts
Built-in editing tools inside converters don’t seem like excessive features. In fact, you can take advantage of them to trim out unwanted intros, black screens, or ads. In addition to saving space, it’ll give your video a more polished and professional look.
Batch conversion for efficiency
Converting files one by one in sequence would be a pointless waste of time. Why would you want to do this when there are tools that offer batch processing? You can upload a whole folder and make yourself tea while you wait for the results.
To sum it up
The FLV format itself is a relic of the past. However, your old videos don’t have to be. You can give them a new life by converting them to a more widely used format like MP4. There are five premium tools that can help you breathe new life into your media library.
