1920×1080 30p CS4 export to MPEG2-DVD black bars on sides
Hello,
I bought a HMC150 and opened the .MTS files into premiere CS4 and export it either as a MPEG2-DVD 16:9 1.0 square pixel (same as video file and project) or as a DVD folder in encore, and both situations produce a video that looks like the following picture. I want to note that if I use the MPEG2 present these bars do not exist, they are ONLY on the MPEG2-DVD and any type of DVD export option in premier or encore. Rather than have to convert the MPEG2 into a DVD folder, I would rather create the folder directly and not lose any quality, therefore I need to get rid of these bars with the DVD Folder export.
If it outputs that way to my 16:10 computer monitor (and yes I know that’s why there are horizontal black bars, but why vertical?) when playing the VOB files in VLC player, it will output that way onto DVD as well. I don’t understand, I have read about PAR but what I read said that on the actual export these bars would disappear and only show up in the (output) tab.
Can anyone help me? I am hesitant to edit this 2 hour project until I know for sure that I wont have to remake the project settings.
Thank you very much

It sounds like you are only previewing this on a computer. Do yourself a favor and burn a quick (short) sample to disc and go watch it in your living room using a set-top DVD player, computers are not reliable for proofing projects. See what it REALLY looks like to the end user.

In CS4 Adobe change or rather corrected the PAR to Britsh standard.
That is why you are seeing those small vertical bars. The only way to get rid of them is to crop the image in the export setting, but will give you some qualityloss as it has to be recalculated. Most tv sets or lcd tv’s are overscanned so you wont notice. Playing your on a pc or laptop: yes it will show.
If you do not like these vertical bars make a feature request, your voice will be heared.

Thanks.
But is there a reason why this only occurs on the MPEG2-DVD and DVD folder export on encore, and not the computer MPEG2 (or any other filetype export) for that matter?
If it was just due to the British Standard than why would it alter the NTSC output and not just the PAL output?

Hi Jeff,
You are indeed seeing a production frame.
You can get rid of those if needed by cropping 8 pixels on left and right.
Mpeg2 DVD creates a specific frame size that has to adhere to DVD standards, are you using the exact same settings (same PAR including decimals) on your other exports?

I see, thank you.
If I do change the resolution to 720×480 on the MPEG2 non-dvd export I will get the black bars. However, if I simply bump it to 721×480 they instantly disappear, so I don’t even have to crop 8 pixels, though this cannot be done on the dvd obviously. I guess I am just confused because you don’t see these bars on any professional dvd, yet I highly doubt they cropped and risked distorting the image to do it. Whenever I watch a dvd on my pc monitor I don’t see these bars, but on my dvd’s I do. I should also note that the blu-ray exports do not have this problem.
Here are 3 shots.
1. MPEG2 720×480
2. MPEG2 721×480
3. MPEG2-DVD

Jeff,
Here is a link that should clear things up for you.

This how you crop. Example is for hdv to sd but workflow is the same.
Then go to the output tab and check if the bar have gone. Make sure it is set to scale to fit.

I should also add this link to a video in case you missed it in the article that explains exactly what you are seeing.

This is on after Effects, but the same applies to Premiere.
