Hi,

I'm new to Adobe Premiere, so I do apologise if you perceive my question to be simple-minded in some way.

As the subject explains, black boxes appear in my exported file and I can't seem to figure out why this may be happening. I have played around with the format, preset and aspect settings and none seem to resolve the issue. The sequence content consists mainly of images if that is helpful.

If anyone could offer some guidance that would be much appreciated.

Don't worry. You will NEVER be as simple minded as me, and these guys help me all the time. What is the aspect ratio of your original file, and what codec and/or format are you exporting to? Some formats will change the aspect ratio. Look at the description below the format and it will say what aspect ration it's exporting at.

I think Duke is on the right path here. It looks like you have some issues with not matching aspect ratios. A few questions:

Do you have black bars in program monitor as well?
Or do they only show up after you export?
In which video player are you watching the exports?

A bit more information helps us a lot to narrow down your problem!

Hi,

I have since been playing around with different aspect ratios and managed to resolve the black sidebars, however now I have letterboxing instead. Neither of the black bar variations has ever been visible within PP itself, I can only observe them after exporting the file and playing it in either VLC media player or once uploaded to YT.

The goal of the project is YT, and they make it clear that unless the video has a 16:9 aspect ratio it will be formatted with black bars. For this reason, I am using a widescreen 16:9 ratio setting in PP, but that doesn't seem to be working.

Does the original document properties need to have the correct dimensions? In my mind, I assumed PP would correct or at least crop them to the required to aspect ratio/settings. Importantly, most of the files are PNG and not video clips.

Thanks in advance

What's the aspect ration of your .PNG files? When you create a project do you have the proper format set, out of that long list of formats? When I had my Nikon D5500 I set it to "DSLR" and it stayed that way. When I got the Panasonic G7 and started shooting 4K, at first I forgot to change the format, and it defaulted to RED Cinema, for some reason. Since it doesn't have a specific 4K editing format I have to use "Custom". If your defaulting to some format that's 4:3, then there's your problem right there.

Hi,

Most of my files are all still images created in illustrator and the document properties of each varies considerably, however, I have generally resized them to my liking with PP and they seem to look good from the preview. Although, obviously I'm doing something incorrect as I'm getting the black bars?

What are your sequence settings and what are your EXACT export settings? Take screenshots.

Any pointers would be appreciated. Still not resolved.

You're using DV widescreen pixel aspect ratio when it should be square pixels.

Also is there a reason your sequence is set to interlaced lower fields?

Looks like you are using the wrong pixel aspect ratio. Try using square pixels. You have to use almost always square pixels unless your footage demands otherwise!

To build on the good advice others have posted, the core of the issue is that the original Sequence Settings that you are editing with are just not correct. Seems that perhaps you started with a PAL DV Widescreen preset, then manually changed the dimensions to those of 720p (1280x720) however the pixel aspect ratio for 720p ought to be square (1.0) but you have retained the 1.2 PAR from the DV widescreen, and also 720p is always Progressive yet Lower Fields are specified. In short, the whole works is off and the results will not be good.

Here's what I would recommend - use File > New > Sequence to create a new 720p sequence. I'm assuming you may be in Europe due to the frame rate of 25fps? From the available presets, choose AVCHD > 720p > 720p25 (or choose 720p30 in the US).

Next, go back to the original sequence, and hit CTRL + A (Select All) then CTRL + C (Copy) to copy entire contents of timeline, then open the new 720p Sequence and CTRL + V (Paste) and that will place everything from first timeline into the new 720p timeline sequence that has proper settings for 720p video.

That being done will eliminate weird issues. However, any stills that are not 1280x720 may have some black around them since they may not completely fill the frame, that is normal. You can right-click said images and choose "Set to Frame" and that will size them to best fit the screen.

Now when you export, choose a 720p25 preset, such as H.264 > YouTube or whatever your needs are, and being 720p25 the output settings will match the source (Sequence) settings and no more weirdness with black edges!

Just keep in mind that the Sequence Settings are the foundation for what you are building. If the foundation is not good, the end result cannot be good either.

Thanks
