I usually fail to upload videos to YouTube, what is the matter?

There is some reason that can contribute when the upload continues to fail. These mistakes may include:
Uploading a file that is too heavy for your internet connection;
Uploading long videos especially when you may not be authorized;
Your browser may be obsolete and doesn’t support the format of the video;
Most importantly, you might be using a format that is not supported by the server.

Part 1. What Files Can be Uploaded to YouTube?

One good thing about websites like YouTube is their ability to acknowledge many different file formats, making it easier for home users to chip in. Although any format can be used because YouTube converts them into an FLV. However, it does not hurt to understand the rest:

MPEG (MPG)

YouTube advises the use of MPEG4 (Divx, XviD) with MP3 audio. This selection probably offers the best compromise between file size and quality. Additional versions of MPEG are also acceptable.

AVI

Many editing programs use AVI as a default format. It presents excellent picture quality however file sizes are large. Therefore, this is a great option for short videos.

MOV, WMV & Others

These are perfectly suitable but might not provide the same small file sizes or quality as MPEG4.

You can upload just about any video to YouTube, including the video you shot using your mobile phone, to your most up-to-date HD video production. You may be astounded to find out that YouTube will even acknowledge high-quality video formats like DNxHD, ProRes, a nd uncompressed 10-bit HD video but this does not mean that you should upload uncompressed HD. For one thing, they will take a long time to upload your file. But even if time is not an issue, there will be a few conversion details that you have to be cautious about.
