What If the Video File Is Not Supported or Too Large to Upload?

YouTube accepts limited video files and endures a long video processing time especially when the file is too large or the exported video is in wrong settings. Don't worry, Winxvideo AI can fix the problem by converting any video to a file format that is perfectly fit for YouTube.

Part 1. Preparing to Upload Video to YouTube

YouTube 4K uploading error can be caused by various reasons, from the poor computer configuration, improper 4K video specifications, to bandwidth of network and so on. Let's take a closer look of the culprit of 4K video not working properly on YouTube.

What Video Format Does YouTube Support?

Before you upload the video to YouTube, make sure the platform supports your video format. We are lucky to find YouTube supports a wide range of formats including 3GPP, AVI, CineForm, DNxHR, FLV, HEVC, MOV, MP4, MPEG4, ProRes, WebM, WMV, etc. In the meantime, audio files like MP3, WAV, etc cannot be uploaded to YouTube. You can check the full video format list supported by YouTube.

If your video file type like .wlmp or .mswmm isn't supported by YouTube and you get the error message like “invalid file format” when you are uploading a video to YouTube, you need a video converter to convert the video to a supported format first.

What Size Should Your YouTube Video Be?

Landscape? Vertical? Square? Sometimes, you may record a video vertically, which isn't preferred by YouTube media player. So it's necessary to crop your video to 16:9, a standard video aspect ratio that YouTube accepts on a computer. If not, YouTube may add paddings for optimal viewing.

In the meantime, uploading large-sized videos such as 4K is quite time-consuming, especially when you have a slower link from home, maybe do that overnight. So we highly recommend you convert the 4k file to 1080p video before uploading it to YouTube. In the meantime, video length is limited to 15 minutes or less.

What Video Tools Should You Use before Uploading to YouTube?

There are a lot of video processing tools that can deal with video converting, cropping, and compressing. However, the biggest struggles are most tools process video files speedily at the cost of quality degradation or maintain a higher level of quality yet transcode video at a relatively slow speed. If you need a tool that well balances the quality and speed, here are the 2 useful tools to help you convert and edit video content before you post the video to YouTube platform.

Troubleshooting Steps to Common Video Uploading Errors on YouTube

1. Get an Error "Invalid file format" or "The server has rejected the file".

File formats such as .mswmm, .msdvd, .wlmp, .camproj, .dvdproj, .rcproject, .piv, etc are not supported by YouTube, and you cannot upload video to YouTube, let alone the video files like PCM, MP3 and WAV. Make sure to convert video or audio in the right format that YouTube accepts first.

2. Get an Error "An error has occurred while sending data over the network" or "A network error has occurred"

Generally, outdated browser is the root cause if you have the problem with uploading video to YouTube. You need to upload the browser to the latest version and then check if you can publish video to YouTube successfully.

3. Get an Error "Failed (empty .mov file)"

If you cannot upload MOV video to YouTube and get the error, it generally means the QuickTime movie is saved as a reference movie rather than a true video file. Please make sure to select “Save as a self-contained movie” and then upload the video to YouTube again.

4. Why my video stuck during upload on YouTube.

A common frustration is that when people are uploading videos it takes forever like 2 hours or more. This issue that people struggle with when uploading videos to YouTube is that their file size is way too big. Typically, the bigger the file size this is, the longer it is going to take to upload to YouTube. If the video is exported in the wrong settings, it makes the file way too big and therefore wasting hours of uploading time. According to YouTube recommended settings, you can export video in MP4 H.264 format with a video resolution preferably in 1080p. So when you create a video before uploading it to YouTube, make sure the video file you are going to have is small in size and is saved in MP4 H.264 preferably.

5. Why does YouTube ruin my video quality?

Many users complained that YouTube degrades video quality. That's not the truth. Generally, high-quality video will initially be processed in low resolution on YouTube, as a move to complete the upload process faster. Once the high-resolution processing is finished, the high-resolution video will be available on your video in YouTube.

Part 3. After Uploading Video to YouTube

Once you've successfully uploaded the video to YouTube, you can share the link with your friends, and family, and on social networks, let your follower on other platforms know to get as many views as possible. In addition, you can partner with influencers to reap the benefits of reaching more audiences. Make sure to stay informed about what's trending and therefore grow your channel.
