Video Framing

[Will Brown]

I am confused as when rendered the black bars are added, to it looks like its 16:9 with the actuall movie 2.21?

[Will Brown] “I shot it in 1440×1080, and I have cropped all clips to 1440×800 and I am exporting using those dimensions too.”

Why would you do that? You are throwing resolution away needlessly. 1440×800 PAR 1.0 is 16:9 (or 1.8:1). Your original footage is 1440×1080 PAR 1.3333 which is the equivalent to 1920×1080 PAR 1.0 which is 16:9 (or 1.8:1). So you just chopped 480 pixels off of your width just to get the same aspect ratio (16:9). This was not a good idea. Especially if it’s going to film where you want all the resolution you can get.

[Will Brown] “I am slightly confused between the PAR and AR.”

Lots of people get confused. AR is the Aspect Ratio of your video. PAR is the Pixel Aspect Ratio of the individual pixels that make up your video. One is at the pixel level, the other is the whole frame’s aspect. They have nothing to do with each other (but they do affect each other).

[Will Brown] “In Vegas, my project settings are PAR Square, and in my rendering settings it is also AR Square, I am using the HDV 1080-50i setting.”

If you are shooting HDV footage, you should use the HDV or HD project settings and do not mess with the PAR. Sony has set it correctly for those formats. HDV is 1.3333 and HD is 1.000. If you make HDV 1.000 you are going to have problems. If you want the PAR to be 1.0 you need make the project HD 1920×1080. If you want the project to be HDV you need to leave the PAR at 1.3333.

[Will Brown] “I was trying to go for the 2.35 or 2.21 AR, I think my Video Framing is 2.21?”

According to everything you’ve told us, your framing is 16:9 (1.8) in which case Full is the correct answer to the question they are asking.

If you want your framing to be 2.35 you need to change your project properties to 1920 x 817 PAR 1.0. Then crop all your footage to 1920 x 817. Finally, render to 1920 x 817 PAR 1.0 and answer the question Full or render to 1920 x 1080 and answer the question LB 2.35

I’m assuming here that by “Full” they mean no letterbox.

You probably should have asked this question before you started the project knowing that you were using a non-standard aspect because I’m afraid there may be some rework required to get the desired effect. Read my answer to your other post and see if it helps. If not… ask more questions. 😉

Wow, thanks John,
I will have a think, but yes, I knew somehing was up when i burnt it to dvd and had 20% of the screen cut off, I was just going to letterbox it.

I will get back to you.
Thanks again.

Feel free to ask more questions. Once you set your project up correctly, you can easily crop the footage by going into Pan/Crop and right-clicking the frame and selecting Match Output Aspect. This will crop the footage to your project aspect (AR).

Hi John,

Thanks again.
OK, a few questions.
1. For my records, what AR is 2.35:1? (Obviously not 16:9)
2. Does HDV look the same as HD, I expect yes, due to the PAR?
3. Finally, what would you do?

Would you convert from HDV to HD 1920×817, PAR 1.0, 2.35:1?
Or keep HDV 1440×613, PAR 1.333, 2.35:1 (I think its 613?)

I presume the whole point is that we (I) do not want to loose the 467 from the x1080 footage.

So, keep it as HDV is my feeling, so what is the AR for 2.35 for HDV, I think it might be 1920×1080 using 1.3333….John?

John,
Is this wrong:

HDV 1080 – 1440×1080 says it 4:3?

[Will Brown] “1. For my records, what AR is 2.35:1? (Obviously not 16:9)”

It’s about 21:9 or 16:7 depending on how you look at it.

[Will Brown] “2. Does HDV look the same as HD, I expect yes, due to the PAR?”

Yes, 1440 rectangular pixels are the same width as 1920 square ones.

[Will Brown] “3. Finally, what would you do?”

If I wanted the cinematic 2.35:1 look I would start by setting my project to the HD 1920×1080 project template and just change the height to 818. (HD is already PAR 1.0) I know I said 817 before but it dawned on me that some codecs, like MPEG2, need an even number of lines so round up to 818. Keep the deinterlace method at the default which is Blend Fields. Then crop your footage to match the output aspect and render to 1920 x 818 PAR 1.0. There should be no surprises and everything will look just the way you want it.

Yes and No. 😉 That calculator is assuming square pixels. You cannot use it to do non-square pixel calculations. 1440 x 1080 PAR 1.0 is 4:3 but 1440 x 1080 PAR 1.3333 is 16:9. You have to convert to square pixels first to use that calculator. It really needs a PAR setting.

That is what I will do.
Thanks again John.
