Latest version not compatible with Monterey

This is a great app, but the latest version (3.8) is not compatible with Monterey. The exported movie gets deleted as soon it finished the process.

Hope this gets resolved asap.

Hi, update to the latest version of macOS Monterey and Submerge 3.9.1 and everything works as expected

Great for Addressing Accessibility Needs

I was seeking a way to embed captions in a video for users and students that are hearing impaired. Many of the places we securely post instructional videos still do not allow for the use of a VTT, TTML or SRT file. Obviosuly, it's ideal to use a file, since it also provides the ability to assist the visually imparied. Sadly, some tools still do not allow for it. In these cases, having the ability to embed the caption in the video itself is incredibly helpful. When using an MP4 and importing a VTT formatted file, it works flawlessly. The exporting fucntion as included has virtually all of the formats we need and can use. I would caution folks to be sure they have properly formatted files. Having files that have flaws (which is common if you have to do it manually) can cause issues no matter what tool you use.

Still broken in OSX Monterrey

I am a frequent user of Submerge 3. Loved it because it would allow you to customize the font used for subtitling (the company I work for has its own proprietary font). However, after updating to Monterrey I tried to embed subtitles and app would generate, but last 5 percent would simply stop and mark as complete, and video would disappear from the folder it was being created in. Followed developer's suggestion to update since this provided fix and still no luck.

Contacted developer via their support page 3 days ago and no response, which is unusual from Apple Developers. If this works it's awesome, if not then useless. Hopefully developer will update once more (or reply to their support requests) ASAP.

Hi Sole. Been busy fixing this very hard to find bug. Sometimes Apple just changes stuff without documentation or explanation :-( This was the case this time also… but I think I finally fixed a workaround. Please download 3.7.8 and give it a spin. Beta tester have confirmed that it works now.
