16:9 / 4:3 Issues
Hi folks
I have a bit of an issue with regard to a video I’ve created. I’m kinda new to this whole video editing scene and have recently started a course at my local college.
I’ve been editing a music video for a local band in Adobe Premiere Pro CS5. The footage has been shot on a couple of different cameras, I’m not sure the exact specs of each camera, but it would appear as though one shoots in 16:9 and the other in 4:3. I’ve interpretted the 4:3 footage to PAL Widescreen (16:9) to get it to similar dimensions as the camera shooting in 16:9 (and stretched it out to fit exactly).
My project and sequence are also widescreen 16:9, with a pixel aspect ratio of around 1.49.
I’m exporting as Windows AVI, again with a pixel aspect ratio of around 1.49.
My problem is that when I upload the video to Youtube, it squeeses the video to 4:3 with black pillars either side. I’ve also noticed that on some monitors, when I play the exported video it displays as 4:3 instead of 16:9. When I open it in WMP and look at the properties it says “4:3 actual, 16:9 displayed”.
I also notice that the dimensions are 720 x 576……but when I look at it in Premiere Pro or WMP it displays widescreen……although sometimes for the first split second it seems like 4:3 and then changes to 16:9.
If someone could give me a few pointers I’d be truly grateful. I’ve been stuck on this for weeks and the deadline for getting it on youtube (to start with) is this Monday……panic stations.
Thanks a million in advance!

The first thing you need to do is determine what are (as you put it) ” the exact specs of each camera”. You need to know what you are working with and your aspect ratio is determined by these three things:
1) Country format. NTSC or PAL.
2) Resolution.
3. Pixel Aspect Ratio.
In Premiere CS3 you can right click on the clip in the project folder and go to “Properties”. That should tell you all that information.
Find out those three things on both your cameras and then go from there. Then you can determine the best project settings for your intended output. -
Windows Media Player and most other computer-playback options are expecting square pixels (1.0 aspect), so you will need to change the output parameters to reflect that.
With NTSC, square pixel 16:9 comes out to 864×480. For your PAL, I believe the answer is 1024×576, which you can manually enter into the output settings of whatever codec you choose.
Regarding codecs, choose H.264 in Adobe Media Encoder and there is a preset for YouTube Widescreen SD (640×360). In any event, I would not create an AVI for upload, it will be huge and take forever to upload.

For CS3 PAL that would be 1024×576.
CS4+CS5 require 1050×576.If you use the Youtube preset you cannot go wrong, it works perfectly.

Lads, thanks a million.. I can’t believe I didn’t see the youtube preset!
One thing though, when it’s up on youtube the resolution is set to 240p and there’s no option to go 360. Any idea why this is happening? There seems to be a serious drop in quality from the video I bounce from CS5 to the video I view on youtube. Any ideas?
Also, assuming I didn’t mind waiting for an .avi to upload, would there be any advantage in going with that format?
Basically, I need to get this video up at the highest possible quality I can, because a lot of people will be looking at it and once the video is launched, I won’t be able to take it down. It’s gotta be widescreen and I’ve got 720×576 pixels. When I use the H.264 youtube SD widescreen setting, and uploading that, it doesn’t give me a great result at all…
Any help at all lads and you’ll be removing an awful lot of stress from me!

Set the level to 3.1 that will give you 720×576 and 480p on YT.

Thanks for getting back to me, but I’m afraid my level is already at 3.1 🙁
At the minute I have a video that is originally 720×576, which I am exporting as h.264 widescreen youtube SD, with the level set to 3.1.
In youtube its only coming up as 240p….which isn’t great to be honest.
Another small issue I have (on the prem pro side of things) is that it seems to be producing a thin black letter box on the top and bottom of the exported video. It’s not in the original. The black bars aren’t huge though, only a few pixels on the top and bottom….
-
I just tried 3.2 and gave me 480p. I do not think you can do much about the black lines.
-
The black bars are there because DV 720×576 anamorphic isn’t true 16:9 it’s a bit wider so the bar appear when you use a 16:9 square pixel frame.
The at around this is to use the crop feature in AME. set it to 16:9 and cross reference the source to the output and you will see it cuts a bit off the sides to compensate.
Let us know how you go.

The bars appear aswel in widescreen setting as in square pixel.
Good tip about the 16×9, I tried to crop manually in the export settings, did not work. -
Thanks a million folks. Really appreciate all your help. The video is uploaded now and just after going live. Feel free to take a look and let me know what you think…..but go easy…..it was my first music video!
