Video from Mavic and gopro has different size

[Leecsjimmy]

Hi

I am new to premier pro and I seriously need help.

When I put on videos on the time line, the Mavic drone video and Gopro video don't match in size. The Mavic video is the first one on timeline and the size is full screen. Then the gopro videos has 2 back bars on the side.

1. I tried scale to size on the gopro video, and basically it just zoomed in the video, cropping a big chunk of the video away.

2. I tried to change both video aspect ratio to 16:9, both the videos has top and bottom black bars, and even then , the black bar on the gopro video is different thickness from the Mavic ones.

Please help

We'd need the frame-size of both cameras, first. So some info on the specific frame-sizes and aspect ratios you're shooting would be a good start.

Thank you for replying.

I am sorry, I am very new to video editing. May I know how I can find this information through the premier pro interface?

i found this:

Mavic video properties :

Type: MPEG Movie

File Size: 651.79 MB

Image Size: 3840 x 2024

Frame Rate: 23.976

Total Duration: 00:04:03:08

Pixel Aspect Ratio: 1.0

Gopro 4 properties:

Type: MPEG Movie

File Size: 517.35 MB

Image Size: 1920 x 1080

Frame Rate: 59.94

Source Audio Format: 48000 Hz - compressed - Stereo

Project Audio Format: 48000 Hz - 32 bit floating point - Stereo

Total Duration: 00:01:36:05

Pixel Aspect Ratio: 1.0

I hope the above information is helpful. Thanks guys!

They are of different resolutions.

Best is to choose a 1920x1080 timeline and drop everything into that,

The Mavic you can Set to Frame Size (right click on clip) on the timeline. But you stilll have black bars, you need to reframe (scale) in the Effect Controls.

thank you Ann

i follow your guide and tried 2 ways:

1. i scale the magic footage to frame size : however, the image now appears zoomed in and the details at the left and right are cropped away. then i overlay the the go pro clip and increase the height of the image taller to match the magic footage.

not so ideal because my drone footage has a lot of details missing from the 2 sides.

2. i tried to leave the magic footage alone. now i overlay the 2 clips, and adjust the height lower for the go pro clip (which is taller with thinner black bars) to match the mavic.

now i am wondering if the go pro clip is actually 'squashed 'and will make everything 'fatter'?

Is there a way to make the the clips match in frame size with our distorting them (in no. 2), or have the sides cropped off (as in no. 1)

[Leecsjimmy]

i realised one thing (may be obvious to you guys, but i am new so please bear with me)

if i Set to frame size, and check Uniform Scale, nothing is distorted. so when i expand my go pro , naturally some side will be clipped away. could the solution be shooting the go pro in wide (instead of medium) so that I can have some excess to clip away?

[Ann Bens]

Uncheck Scale to Frame Size in the Preferences.

Dont uncheck Uniform Scale.

Use Set to Framesize not scale to framesize in the timeline. (latter will scale to 100%, former will stay original resolution)

If your sequence is 1920x1080 there is no clipping on the gopro.

Start fresh: right click on a gopro clip in the Project window and hit New Sequence from Clip.

If you drop the drone footage in the timeline it will be zoomed in.

Now hit Set to framesize and adjust further in the Effect Controls.

Shooting medium or wide with the gopro in 1080p wont change the resolution of the frame just the picture itself.

When I did the above, I need to scale the Mavic footage (3040x2024) so that it can fill up the top and bottom black strip,  meaning the sides will be slightly cropped.

I realised that the Mavic can also shoot 4k in 4096x2160. Given this other setting, does it mean that I can crop lesser from the sides because it has more image on the top and bottom since its a little more 'squarish' ?

[R Neil Haugen]

You want to match aspect ratio as close as possible. The 1920x1080 is standard 16:9 aspect ratio.

With a 2160 height the matching width would be 3840. So that 4k setting of the Mavic is just a bit wide.

From the numbers you've given us for the Mavic your choices when shooting are to have a bit cropped off either top and bottom or the sides, to try and work that with the 1920x1080 standard 16:9 media and sequence.

Choose one option and allow for the cropping that will be needed while shooting.  For most of us, we'll plan on loosing a few pixels rather than show a black bars.

Thanks Niel

You guys have been really helpful so far. I have another question.

I realised when I downscaled in the above method, the end resulting 1080p video (from mavic) doesn't look very good.

I read somewhere that if my sequence is set in 4k, then output in 1080p, the downsampling video looks better....is it true?

If the above is true, and since I need 1080p output in the end because of my gopro videos, do you guys think the solution is to just start a project for all the 4k clips  (sequence set to 4k and output in 1080) , and use the resulting video to build another project to combine the clips for both mavic and gopro videos (sequence in 1080 and output in 1080). It's a lot more work for a newbie like me, but if the degree of the preservation of the video quality is significant enough, I may want to try this.

What do you guys think?

[R Neil Haugen]

If using "Set to framesize" ... normally the down-scaled sequence of 4k onto 1080 works great. Taking the 1080 "up" onto a 4k timeline won't look so good.

So maybe post a screen-grab of your sequence settings and of your program monitor ... ?

Thanks Niel

I will start a new project and try again.

Along the way I may have Scaled to Size before I Set to Scale, as I was trying our various settings.

Will update here.

[Leecsjimmy]

Hmm...I tried again and the 1080p still look like crazy.  This is what I did:

Under preferences I unchecked "default scale to frame size"

New project

New sequence - custom 1920x1080 25fps

Import my 4k clip

Drag clip to timeline - this time the 4k clips automatically zoomed in to fit the frame

Export to media - H.264, match source high bit rate, the rest as default as I don't know what to change

What could be wrong?

[Leecsjimmy]

i think i may have found the problem. i tried again on the Export part and i use the following:

Export to media -  FORMAT: H.264, PRESET : HD 1080p 25

the end result is Great!
