Problem uploading to YouTube...Seems to be Davinci

Dear good people
I am trying to create youtube shorts and link them to my long videos and to do that I have to do it on my mobile phone! The problem is that when I try to upload a youtube short from my mobile I get the message
"unable to preview video"
I have tried a lot of export combinations and different aspect ratio's and each time the same message!

I have read in a forum on reddit
https://www.reddit.com/r/NewTubers/comments/viab8l/unable_to_preview_video_issue_with_yourube_shorts/ that a lot of people are having that kind of problem! Is anyone else having the same problems when trying to upload from cell phone? Does davinci knows about this problem and is there a solution?

Thank you all in advance
Thanos

I use the paid version with the latest version of Davinci 18

Hi Man, same problem here. I have the Pro Version of Davinci Resolve 18. I have to export the video and then use another program to "convert it", just to save it with the exact resolution and fps. I am not changing anything, just using another program to save the file again. A real pain in the a...
I have tried with Adobe Premier and it works without converting. It just happens when exporting with Davinci. And I have tried saving it in .mov .mp4 and many different presets. I get always: "unable to preview video".
So frustrating!

Are there any updates to this problem yet as I am also having this same message "unable to preview video" in YouTube when trying to add my Short YT videos. It seems to be rejects all files types from Davinci.

I have the same problem. Anyone has found solution?

I have this problems since months...

same Problem here !
Anybody found a solution to this?

Same problem! Hopefully BM will sort it out

I can't believe this is still a problem. BM makes a big fuss about "VERTICAL VIDEO" but who cares if you can't actually upload it because there's something wrong with their codecs...

Youtube will clearly have a file specs that must be complide with in order that you can upload. Do the files you prepare meet the required spec? Maybe use a third party tool to check you meet youtube requirements. Mediainfo (free) springs to mind. I can understand yor frustration but seriously doubt it is a BM problem.

I've never had YouTube or Vimeo reject a video exported from Resolve. I also suspect settings are incorrect.

I am also see the same error when uploading shorts on youtube (ie "unable to preview video")
I tried almost all the different formats and settings for exporting from Davinci resolve studio - Issue gets fixed if I take the exported video from Davinci into other editor like VN or similar software and reexport it.

Though this works, it is an unnecessary step. Please Blackmagic fix this problem for youtube shorts creators. (i'm purchased Davinci resolve studio specifically for making shorts)

Here is probably the problem, DR add this QuickTime TC at files even if exported out as MP4.
And it is still the problem with newest 18.6 Studio version.

I've never had YouTube or Vimeo reject a video exported from Resolve. I also suspect settings are incorrect.

I keep getting this error on YouTube shorts. I've tried all settings I possibly could. Can you share your settings for YT shorts, so I could test them too?

Please solve this issue, i have to send the clip to capcut and rerender it just so it works. I upload 20 clips a day on youtube and its a pain in the ass.
18.6 DRS is a banger, btw

Good evening,

I seem to facing a similair problem, however cannot find a solution, even after reading through the forum: I am creating a series of videos and export them as mp4. Out of 12, 10 were exported without any problems. Two of the videos - created in the same fashion as the others are unexportable. In NO format, whatsoever. I can see the data (e.g. 7 GB), when I try to open it with Quicktime (yes, I am running on Mac), the data vanishes and I see an empty shell with 0 KB.
Quite frustrating, especialls, since the majority ran smoothly. I did two videos in one day - the first faced no problems, the second just keeps frustrating me.

Any ideas or hints as how to solve this situation? I tried all the different formats on offer by DR (using the lasted 18.6.1), all in vain.

Thank you for any helpful answer!

.. ive just checked.. and it looks like the problem is related to uploading from Android phones. Is that what you are doing? I can't see reference to that above.

If you upload directly from Mac/Windows or an iPhone, I'm told it's okay.

Good morning Peter,

I am not quite sure, if I understand the term "a .dra" correctly. However, I send you two screen shots, showing the "finished job" before and after trying to activate the data. Quite obviously the finished data also shows a different icon than the previous videos, that function.

Please excuse, that everything is kept in German.

Thank you for patience.
Best regards.

Yes the problem is with Android phones, but that is not the main case here since DR add a bogus ID under the main codec in a QuickTime TC format even if exported out as MP4.

Just check this screenshot where ID 3 should not been there

Not sure if this screenshot link will be shown since my last didn't

I had this problem in the past too.

The advantage of uploading a video from the YouTube app from the phone (Android in my case) is being able to select the frame that is going to be the thumbnail for the YouTube short.

You can't do that yet from the desktop with YouTube studio.

I remember trying to change every setting to see if it was the framerate that caused the problem, the resolution of the vertical video (4k vertical, 1080p vertical), the codec, the container format—nothing worked out of Resolve. Like OP, I found all the other people on Reddit and different forums with this problem with Android.

I remember seeing a video from VidIQ (or from another channel, I don't remember) about how they exported their video from Premiere, put it on their phone, uploaded it using the YouTube app, and selected the thumbnail from a frame of the video. I don't remember if they used an iPhone, but they were using Premiere for sure.

I am a brand new user of DR Studio. I do not have any problem with Premiere, now in order to upload to Youtube from Android, which is the only way to choose a frame as a thumbnail, I need to export to a lossless format from Davinci and then export it with Handbrake or Media Encoder as a H265 vertical resolution.

Same problem.
I export from DR with the YT preset - no other changes. Copy it to my phone (Samsung S22) and from there I can succesfully create Facebook and Instagram Reels, but the YT app can't show me the preview.

Sure, this could be a YT issue, but it still sucks to need to use an app like Kinemaster on my phone to convert something DR has made to make it compatible with YT..
The issue has been reported to YT as well, but no response from that side (surprise).

Ran into this thread, but have a slightly different issue on top of this.

Every other Short I upload to YT will not be recognized as a Short, but as a regular video.
The only way to fix this, is to re-export the video, and upload it again.
It looks like something goes wrong with the vertical format on export?

It's annoying af.... as it is double the work.

Anyone else seeing this?

For Shorts the video need to be in MP4 container (1080x1920, max 1 min long), and the problem with DR and export is that the video will be with MP4 container, but will also have MOV container-ID inside the file.
So only solution is to re-encode with a 3rd party encoder for getting rid of the bug from DR.

If you or other read my latest answer in this thread, I have mentioned it many times.

Ah.. That might explain things.
And don't be too harsh on us, some of us are not native English speakers, technical or ... a tad dyslexic.. These long threads can be hard to follow..

Hehe I'm not neither a native english speaker/writer.

I have just made a video showing this problem, and I post it here so more people will see it and also maybe Black Magic will pick up the issue and fix it.

Is there no update from BMD on this?

That doesn't seem to be true, It may display in that resolution as a short but you don't need to upload at that resolution, but for now until they figure out their problem they may as well to not confuse things. The first short I saw after reading this is:

https://www.youtube.com/shorts/xWXD8YqfzDM

It's resolution is 2160x3000 as can be seen by the non short formatted version

Thank you for spelling it out. I've been studying on how to use 'ffmpeg' to delete that code, but to be honest, I'm not that advanced yet. This is a real problem, that a lot of people are having trouble with, and have been voicing their concerns about, so I hope the BM people can eventually get this straightened out.

Code: Select all

ffmpeg -i input.mp4 -map_metadata -1 -c copy output.mp4

(It's the same for a .mov file)

I'm on Windows, so what I did is to open the folder with the file, write "cmd" in the address bar of the folder, and just write this code (change the names of the input and output).

It effectively removes these metadata (the "other" seen in MediaInfo in the video of Joahnsenfoto).
And it won't transcode anything. It just makes a new file without these metadata.

I personally didn't test this method to upload a short from my phone yet.

That works! It removes, "other", and uploads as a short from my android without the annoying, "unable to preview video" pop up. Now, I do not have to re encode using Handbrake, or a similar program.

Thank you!!!!

The only problem is that the video are not HD when uploading them from the Android YouTube app

Seems a bit complex but did from YouTube to verify that you upload short from phone

I tested this FFMPEG command, and it worked. It doesn't cause issues anymore.
I wonder why BM is taking so long to fix this issue!

I created a python script that would automate this process. Thanks to all the above comments.

A brief description and tutorial is also written in README.
Enjoy

I believe a short will only appear on YouTube as an SD, BUT, I have seen some guys showing how they upload 4K shorts. The way I look at it the screen is so small, who cares....

For some reason I'm not allowed to post urls here...even though they clearly have a url function...whatever..anyway..first go to YouTube, and search for, "How To Install ffmpeg". There's a bunch of vids..once you have it installed, just follow Videoneth's instructions. If you already have ffmpeg installed, and have tried to follow his instructions, and still can't get it to work, I'll help you out.

I created a python script that would automate this process.

I think the same would be easier to do with a batch file in windows, or bash script in linux/macos etc.

As it's only running external program and getting a parameter from command line.

Most people don't have, don't know they have or don't want to install python and some modules just to run ffmpeg.

so the batch file could be ripmetadata.bat:

"c:\Program Files\ffmpeg\ffmpeg" -i %1 -map_metadata -1 -c copy output.mp4

and be called like
c:\data\videos\>ripmetadata original.mp4

bash script would be similar.

Yes maybe idk. I use python, so I went with python. Python file would run automatically after each render, I don't have to run any script myself.

Wow, thank you! It worked for me! Here's some QA.

First I've tried to name a video in Deliver settings as yt-short instead of coded in script yt-short.mp4, assuming it'll have .mp4 format after the render anyway. But it doesn't work like this, the File Name should be with .mp4.
I thought it's worth mentioning in README.md and have even made a pull request with according changes.

and be called like

Batch file also works, and here's alternative way to use it. Note that source video in this case should be named input.mp4.
I've created ripmetadata.bat file with the following contents:

Code: Select all

ffmpeg -i input.mp4 -map_metadata -1 -c copy output.mp4

(You don't even have to specify a path to ffmpeg.exe if it's added in Windows global PATH.)
Then putted the file into a folder with a video and ran it. It have also removed metadata.


In the end I think the Python method is more convenient (though may be more complicated in installation) as it decreases unnecessary actions like moving batch files between folders, renaming videos and launching Windows CMD\PowerShell.

Of course you can put the bat file where ever you like, even on your desktop and then just drag&drop the file to be cleaned on it. The code below is probably good enough for occasional fixes, but miss the protection for many cleaned up files as they all end up getting the same name. Of course the name could be processed from the original but I leave it to someone who is more interested in it

clean.bat

Code: Select all

@echo off
set dest_dir=t:\temp
echo Cleaning up metadata...

ffmpeg -i %1 -map_metadata -1 -c copy %dest_dir%\cleaned.mp4
echo All done! File created as %dest_dir%\cleaned.mp4
echo you can now close this window
pause


Today I face this problem. Hope Blackmagic fixes this soon.
