Among them, VideoProc Converter AI is the most powerful tool that can upscale and enhance videos with Super Resolution, or downscale/compress 4K videos while maintaining the best quality.

Today, consumers enjoy unprecedented access to 4K videos through devices like the iPhone, capable of shooting in 4K at 30fps/60fps, as well as GoPro and DJI capturing UHD videos. Various platforms also offer streaming of 4K content, spanning Cinema 4K, 4K 4:3, and more. However, the transition from capturing these high-resolution videos to working with them, whether for playback on TV/Windows/Mac or editing in applications such as Premiere, iMovie, and DaVinci Resolve, can be daunting. Challenges like sluggish performance, compatibility issues, and potential crashes on computers often arise. This is where a reliable 4K video converter proves invaluable.

When selecting a 4K video converter, several crucial factors should guide your decision-making process. In addition to addressing the aforementioned issues, it is essential to consider the 4K resolution of your original video. Verify whether the converter supports various 4K video resolutions at different aspect ratios, including 4K 16:9, 1.9:1, 4:3, and more. Delve into the detailed descriptions of each tool provided below, ensuring that you choose one that aligns with your specific needs and requirements.

1. VideoProc Converter AI

VideoProc Converter AI is the overall best choice to convert 4K and large videos. It supports 420+ output formats and 370+ input formats, including 1080p, 4K HDR, HEVC, 10bit videos, long-GOP from DJI, GoPro, variable frame rate (VFR) videos from iPhone, 4K MTS/M2TS and MXF from camcorders, and other demanding video files.

If you are experiencing the "playback error", you can use VideoProc Converter AI to upscale 240p/360p/480p/720p/1080p by 2x, 3x or 4x with Super Resolution, remux the 4K container or transcode to a device-compatible format. If you prefer to save storage space and relieve CPU overheat, you can downscale 4K to 1080p without quality loss (using the high-quality engine in this tool). For editing in FCP, Premiere, iMovie, Sony Vegas, DaVinci Resolve, etc., VideoProc Converter AI supports processing 4K video to ProRes (editing-friendly codec).

VideoProc Converter AI as the Best 4K Video Converter for All Situations

This 4K video converter solves these issues and beyond:

  1. Upscale video to 4K: Upscaling 720p/1080p to 4K in certain scenarios, powered by AI. Some users are trying to do so not because they want to fake a 4K video. Instead, the specific use case can be, you are editing on a 4K timeline with footage from various resources, and you prefer to convert a video to 4K to streamline the process.
  2. Downscale 4K to 1080p: Downscaling 4K videos to lower resolution to save storage space, go for quick sharing where quality is less a matter.
  3. Compatibility concerns: Dealing with playback errors on TV, Windows/Mac, uploading correct 4K format to YouTube and editing smoothly in DaVinci Resolve, etc. Converting 4K MKV to MP4, MOV for playback, or ProRes (intermediate codec) for video editing.
  4. 4K video stuttering or lagging: Some devices fall short on 4K HEVC, 4K 10bit, or 4K HDR videos. Plus, iPhone that shoots VBR (variable frame rate) 4K video can be problematic for editing software. 4K converter can change codec, convert VFR to CFR, and manage other codec settings.
  5. Convert 4K to the best quality at smaller size: This is handy for 4K files from iPhone, GoPro videos, DJI, and DLSR cameras. Depending on your settings when recording the video, the file size can be unnecessarily large. With a dedicated video processing tool, you can convert 4K video and make it smaller – no matter whether you decide to keep the original resolution or downscale – without losing quality.
