Significant quality loss after exporting video

Hello dear forum members!

I have made my first premiere pro video so far and I somehow struggle in exporting it properly. I´ve searched through the forum and tried everything, but the quality isn´t getting any better. Maybe you guys can help me.

My Video is a mixture of Camera-Photos, Photos from my mobile phone and videos from several divices. Surprisingly the mobile phone videos are quite ok compared to the original, but also not perfect. I feel like, the better the original quality of the photo or video, the higher is the loss of quality after export.

My Camera photos are 4272x2848.

I used following export settings:

Format: h.264

Preset: Match source - high bitrate

Width/Height: 1920/1080

Frame rate: 59,94

Field order: progressive

Aspect: square pixels

Profile: Main

Level: 4,2

Bitrate encoding: VBR, 1 pass

Target bitrate: 10

Max bitrate: 12

"Render at maximum depth" and "use maximum render quality" are selected

My sequence settings are: AVCHD 1080p square pixels with 59,94 frames and 1920/1080 width/height

After some research, I tried to adjust following:

Profile: High

Level: 5,2

Width/Height: 3840/2160

Target bitrate: 20

Max bitrate: 22

-----------------> same result! Photos lack in resolution and it seems like colors and contrast are a bit different from the original

-> I also tried a new sequence with higher resolution settings, didn´t work as well.

I don´t know what I´m missing here - like I said, I´m farely new to the programm and hope you can help me. I put a lot of effort in making this video and would be very disappointed, if that is the best outcome.

I put some examples below, so you see clearly what I mean. Thank you so much!

No matter what you do to the export settings, if your sequence settings are low, the result will be low

Now wonder its bad: first you are downscaling then upscaling on export.

Alright so there are a few different things at play here, let's see if we can unpack it all...

First I'd start with your sequence settings. Make the sequence resolution match what your export resolution. Making the sequence resolution far higher than your media will mean you may have to scale that media up to fill the frame, which means a loss in quality. That shouldn't be an issue with your camera photos at 4272x2848, but it looks like that's what's happening in your second set of example pictures.

Next, I'd look at your export settings. The main thing that's probably holding you back is your bitrate. To export 1080p60 H.264 at a decent quality, you're going to want at least 12 Mbps. You were on the right track here...

After some research, I tried to adjust following:
Profile: High
Level: 5,2
Width/Height: 3840/2160
Target bitrate: 20
Max bitrate: 22

...but your downfall was upping your resolution as well as your bitrate. Also, I'm assuming those are adjustments to your export settings, not your sequence settings? Target 20, Max 22 should be fine for 1080p60, but you lose quality by trying to squeeze a 4K export out with that bitrate. Try exporting 1080p60 at Target 20, Max 22, and that should help the loss in quality you see in the first set of example pictures.

Finally, as for the color shifts in your exported videos, what program are you using to view them? Whatever media player you're using to play them back may be messing with your color, so it may be an issue there instead of with Premiere.

Ooh, one more thing I noticed from your OP...

Surprisingly the mobile phone videos are quite ok compared to the original, but also not perfect. I feel like, the better the original quality of the photo or video, the higher is the loss of quality after export.

You may also be dealing with different codecs from your different sources. If all else fails, you may want to transcode all your footage to the same codec before bringing it into Premiere.

Thank you very much for all the information!

I followed your instructions step by step, but still have the same bad result. Furthermore I can´t set the export settings higher than 3456/2304, so I can´t adjust the export settings exactly to the image size.

So I tried something new:

I opened a completely new project, just imported the first camera image of the ship and finally just exported that image - sequence settings and export settings are the same -> 3456/2304 (as high as possible)

Surprisingly the output has the same bad quality. I really do not understand what I´m missing here. Again I started several attempts, playing a bit with the bitrate settings, but I cannot see a difference at all.

I will drop my settings below again, maybe you see something suspicious.

Again thank you very much for your time and effort!

Sequence settings:

Editing mode: custom

Timebase: 59,94 frames/second

Frame size: 3456/2304

Pixel aspect ratio: square pixels (1.0)

Fields: No fields (progressive scan)

Display format: 59,94-fps-drop-frame-timecode

I think audio and preview settings aren´t nessesary, right?

Export setting all the same

I also tried it like you suggested, Sequence settings and export settings to 1920/1080 -> also bad result.
