What version of Premiere are you using?
Often, posting a screenshot of your export settings will help.
Would uploading the 1kb mp4 be of any help?
Most of your export settings are not visible,
but nothing jumps out as being way off.
I live in NTSC land, but one thing I notice is you have a 25p Sequence,
and you are encoding to a 50p file...
Wuffo you do dat?
Export did not finish hench the 1 kb file.
No point in exporting to 50p especially for Youtube. Just leave it 25p and try CBR or VBR1
I saw it reach 100%?
I had set it to 25fps but after having a play around then it appears when i set the 'Level from 4 to 5.1' it changes the fp up to 50fps.
I have no idea even what changing the level does i just as previously mentioned followed a youtube video for best export settings for youtube!
Ill give it another crack!
Even if you do change the level you can set the framerate back to 25.
Just set it going again so fingers crossed!
Thanks for the advice, ill report back in a few hours!
Just out of curiosity. What would occur when i set a 25fps video to be encoded at 50fps (forgive me if i have used incorrect terminology)?
