Error uploading video.

[Panoulis64]

I'm running sfm 2.1.4 with PHP 8.2
and SMFGallery10beta2.zip
I have video in Settings
Maximum video/audio size: 2000000000 (bytes)
The video file I tried to upload 44.7 MB(46,890,196 bytes)
I fill in video name, category, text, keywords, select the video, and after almost a minute of it trying to upload, it gives me an error saying I didn't select a category!

In my management, I get 5 unspecified errors every time.
2: Undefined array key "title"
2: Undefined array key "descript"
2: Undefined array key "keywords"
2: Undefined array key "cat"
2: Undefined array key "userid"

All in /home/triglian/public_html/new/Sources/Subs-Video2.php (Line 175-9)

URL of the page generating the error
/new/index.php?action=gallery&sa=addvideo2

and the 5 Flashback information
#0: smf_error_handler()
Call from /home/triglian/public_html/new/Sources/Subs-Video2.php on line 176 (175-9 of 5)
#1: AddVideo2()
Call from /home/triglian/public_html/new/Sources/Gallery2.php on line 295
#2: GalleryMain()

What could be going on?

After the changes you suggested, I tested again, same video and it uploaded.
But I got the following error message:
Database error
Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='
File: /home/triglian/public_html/new/Sources/Gallery2.php
Line: 12523

and in my management

/new/index.php?action=gallery&sa=addvideo2
  /home/triglian/public_html/new/Sources/Gallery2.php (Line 12523) Fallback info

Error Type: Database
Error Message[Select]
Database error: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='


SELECT
ID_TAG
FROM smftm_gallery_tags
WHERE tag = 'Sergiani on the streets of Rafina'

You are going to need to look the table collation and character set for the smftm_gallery_tags table and make sure it matches your gallery tables such as smftm_gallery_pic table. I would check via phpmyadmin
