No true black or white in export for YouTube.

Hi there folks.

New forum member and—admittedly—video amateur here. I use Adobe Premiere Pro CS6 on Win7.

My problem is in rendering MP4 videos out for YouTube. Once rendered, the image has neither true black (0,0,0) nor true white (256,256,256), just very dark grey and very light grey. I've done loads of research online and tweaked the settings like mad but no matter what I do, the output always appears the same on playback (not whilst in Premiere, I should add - that looks great).

I'm using VLC Player for playback - not sure if that'd make a difference.

Can anyone please point me in the right direction to sort this? When replying, please bear in mind that I really know almost nothing about video. 🙂 Thanks in advance.

Kind regards,

Sandyrb.

Hi Michael.

Thank you so much for all your help. Can't deny that some of it's gone over my head but no worries.

I had a brainwave and found some different software to play the render back and it turns out—egg on my face—that this was a VLC Player issue all along. Ohmygoodness you would not believe the hours of head-scratching that this has caused me! But there it is; my videos were fine all the while and it was that damn VLC thing screwing with the dynamic range.

Thank you again for your help; we can consider this one put to bed. 🙂 Have a great day.

Kind regards,
Sandy.

and this could be an issue with the way Premiere handles gamma (contrast) versus how your computer does... Do other videos on youtube look OK?

you live and learn... and hopefully you won't make the same mistake again... just a different one.

Maybe try exporting as a prores file and try uploading that to you tube... I know it will be a much larger file but worth a shot to see if you can isolate the issue...

Hi Michael.

Thank you so much for your response.

Unfortch my Premiere Pro appears too old to support ProRes... I think! At least, I've had a look round in the various export options and I can't find it. Perhaps you or someone else could please give me a hint where it can be found?

Thanks again and have a great day.

Cheers,
Sandy.

CS6 is probably incompatible with hevc also... Prores is what's called a mezzanine format in which every frame is discreet. Do a little googling about mpeg formats to get a handle on what this stuff is all about. I'm guessing your on windows, but always a good idea when posting a problem to tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card.
