Before I get into these steps, I would like to say that the d.tube is very new and are struggling to cope with the number of users. Youtube have 1000's of people working on it to make it work smoothly.

Although this steps have worked for me and many others, you still may have some issues. Read the additional tips at the end if you are still having problems. And still you might have issues, so you will just have to try again later unforetunately.

N.B. This is not facts or science I have just trial and error'd loads of times to find a way to upload video. Other users seem have found this helpful.

Follow the steps below

Step 1 - Create a video

-> format .mp4 and video codec H264

-> audio codec = AAC.

-> frame size 1280x720: -> as for the time being (02/2018), better upload in 854x480, not 720p, especially if the video is longer than 20 minutes.

-> audio channels stereo

Additional tips

Change the video extension tag in lower-case

If you still have issues you might have to encode your video using Adobe Media Encoder.

Step 2 - Add title for the video

This hasn't been an issue for most people. I have used emojis, capital letters, hashtags etc. and not had an issue. Also other people on steemit or reddit have not had many issues with it.

Step 3 - Add Description

I have added very long description not had any issues

Step 4 - Upload video

-Wait for the video to finish uploading

-Do not upload snap until after the video is uploaded

-Issues with video over a 1 GB

Step 5 - Upload Snap (Thumbnail)

File type JPG File (.JPG)

Step 6 - Tags

up to 5 tags

Step 7 - Upload video

Click 'submit'

Congratulations

Additional tips

Change browsers, Firefox seems to work best for me

Golden tip. Log back in using your posting key for steemit account just before uploading to d.tube. This has been the best one for me!

Try again later. I still have issues sometimes, d.tube is still very new so give it time
