Supported Video Formats: MediaKit Upload Guide

MediaKit lists the accepted video formats

The MediaKit enhancement documents list MP4, FLV, TS, AVI, MOV, WMV and MKV as supported mainstream video formats. A container name describes how tracks are packaged; it does not by itself prove that the media is valid.

Artplayer AI checks the actual media after upload. Keep the original extension, preserve readable video and audio tracks, and use an export that can meet the app's H.264 MP4 delivery contract. Renaming .mov to .mp4 in a filename does not convert the tracks.

Check color and framing too

Use 8-bit SDR video. HDR and higher-bit-depth sources need a suitable SDR conversion in your editor before upload. Preview that conversion carefully: a poorly handled HDR export can look washed out or have clipped highlights even before enhancement begins.

Landscape, portrait and square videos are supported, including 4:3, 16:9, 9:16 and 1:1. There is no need to crop or stretch a video just to upload it. Output scales with the original proportions; review the quoted pixel dimensions before processing. Input dimensions must still meet the selected mode’s limits.

Match the file to the selected mode

The current MediaKit enhancement limit is 10 GB per input file. Neither Basic HD nor Advanced Enhancement has a fixed documented input duration cap, but uploaded media still has to pass validation; that is not a guarantee that any length of video will process successfully.

Input is not limited to 30 fps or 1080p. The current output is 30 fps, and its dimensions must be larger than the source. Review fast motion if the original uses a different frame rate. A large input can be valid as a file yet have no larger supported target, so check dimensions before planning the job.

Export a clean source once

If conversion is necessary, work from the best original rather than a previously compressed download. Export one of the documented MediaKit containers—MP4, FLV, TS, AVI, MOV, WMV or MKV—and make sure its tracks play correctly. Keep the source’s frame rate where your workflow allows; the service will produce its configured 30 fps output.

Choose an export quality that preserves useful detail while staying within the file limit. Repeated compression can introduce blocks, ringing, and smeared textures. Play the exported file from start to finish and check sound, orientation, and the first and last frames before sending it.

Use validation as your final check

After upload, Artplayer AI inspects the actual media. A familiar extension or a successful local preview does not replace that check. Read any validation message, fix the indicated property in the original project, and export a corrected copy instead of repeatedly uploading the same file.

If the file passes, the server checks your selected output and actual credits; a higher price requires confirmation. If it does not, keep the original and note the reported format, dimensions, and error when asking for help. Avoid assuming an upload problem means the source video itself is unusable.

• Container and tracks: MP4, FLV, TS, AVI, MOV, WMV or MKV with valid media tracks.
• Geometry and limits: original proportions, at most 10 GB for enhancement, valid media metadata, and within the selected mode’s input dimensions and scale limits.
• Playback and source: correct color, intact audio, intended framing, and an untouched original saved elsewhere.
