Resolve 17 Studio Won't Export Correct Resolution

Hey everyone, I'm a lurker but not in the creepy way, and I've been using resolve now for about a year. I switched from FCPX and have used premier in the past as well.

MY PC SPECS
AMD 3700X
NVIDIA 2060 8GB
X470 MOBO
64GB Ram
Windows 10 Pro

I have the latest studio drivers, I don't even use game ready when playing games, and all that good jazz.

I'm developing a love hate relationship with Resolve unfortunately. It's incredibly buggy at times, especially during random beta 17-whatever updates, and it essentially breaks the program. More on that a different time.

I looked at a tutorial video on how to make particle effects in fusion, because I had an idea from an Instagram ad, and wanted to give it a shot myself. So I did, and all was working well until I tried to export. The first time.

It just wouldn't export. I tried various settings and codecs mp4, QuickTime, h.264, h.265. No dice. So the ONLY solution I found was to do it ALL OVER again. Sure, it's a pretty easy video and takes me about 5 minutes. No problem, it renders... HOWEVER.

When the render starts working... the video keeps cropping in. I go through all the settings again, trying different settings with the image scaling and timeline resolution. Nothing is working. I search the forums, google and YouTube. No luck.

So now I'm here asking for help... Help in trying to make a 10-second Instagram clip for my business, look the way I want it to look. And not crop in again and again and again! It's maddening, especially after getting THIS close.

This program is so great at times... But also makes me want to never open it again, when it doesn't work properly. Really thats almost EVERY NLE I've used... But when resolve doesn't want to work and gets crabby.. well I won't start cursing here

I uploaded a video with crappy titles about my problem. I really just hope it's something simple I'm doing wrong. But I don't know maybe the frustration is surpassing the logic right now...

Posted the issue privately to our youtube channel. It's my first post so I guess I can't post URLS?
Not 100% sure but I can send the video link if needed or post it up later.

This feels as bad as cyberpunk 2077. Somebody please help!

Also, many thanks and enjoy your day!

MP4 and QT are just containers and I'm afraid that you used H.264/265 all the time.
If you still have that project around, try to export DNxHR in a QT container instead. Does that work?

That took me way too long to figure out haha

Sorry for the rushed and bad explanation, as well as the rant. There's plenty I don't know. Also, I actually found a solution based on your reply, so thank you.

What I didn't mention was that the video was based of a JPEG taken from an Iphone. I brought that into resolve and then the trouble started.

I ended up exporting the picture in its own timeline based on its resolution as a quicktime dnxhq file.

Brought that back into resolve, so it would be looked at as a video file instead of an image.

Applied the fusion effects to that video. Then exported it as a quicktime dnxhq file again.

Brought the video file with the effects back into resolve, added the music I wanted. Then exported it as an MP4, H.264. It works fine now.

I think some of the problems I was having was to do with me compounding the clip on the timeline when trying to export. I got some funky business happening, but remembered reading about that on these forums. Guess I'll do some testing later.

Appreciate the help!
