You mean (+/-) ;plus or minus button ? Not the one in the keypad, the button next to 9, 0.

Didn’t matter, the duration can be set independently, you can just click & drag/extend the image.

The easiest and fastest way to do captioning is to use 3rd party tools, don’t worry, it’s freeware.
You can use either aegisub or subtitleedit (nikse).
Personally i use aegisub, because i can work faster with their workflow.
I use aegis because it can import a txt files, that act as a line-by line dialogue transciption.
Aegissub can import that, then i can adjust the timing very fast (you need to practice though).

After you finished making subtitle in that 3rd party tools, you can save as srt and convert into scenarist caption format (*.scc) using Nikse subtitle edit..
Then you can easily import that closed captioning import to premiere.

That being said, if your intention is to burn-in subtitles into video, not as closed captioning, you can use avisynth, then use a pismo virtual system (google it) to “import” as an overlay video files.
Or, using other plugin either in premiere or in after effects, there are plugin that can import srt.

There is another option to export as png files with xml data using nikse. so you can import the srt as sequence, there will be a bit of hiccup, since the path to png will broken, but you can easily solved this using batch and replace.

I’m sorry to being so vague, there’s too many workflow to do this, and i’m just not in the mood for writing a long tutorial.

TLDR :
1. IF you want to do closed captioning : Use aegissub to create subtitle, then convert to .scc files using nikse subtitle edit
2. IF you want to do burn in subtitles : Use aegissub to create subtitle, then either using avisynth with frameserver, or create png files from nikse, or export as video files using AE plugin (not freeware). There ara other to import using 3rd party plugin natively in premiere, but i never tried it.

Quick Google :
https://www.samsung.com/us/support/owners/product/LN46C550J1F

Download the manual, look in page 32, there’s a lot of supported codec/formats info.

Also, take a look at the restriction with certain codec (at the same page, bottom), such as H.264; only support up to level 4.1

use fast preset or use fastest preset in x.264, see if it helps., or use avisynth like i told you, encode with megui with the same x.264 preset.

If it’s only “glue” jpg and mp3, the fastest approach will be avisynth and export with x.264 fast preset, still image tune . Also since the image is static, there’s no need to set a high bitrate (5MBps) for video, what matter is your audio bitrate.

Or you can do this with ffmpeg on one go:
ffmpeg -loop 1 -i image.jpg -i audio.wav -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest out.mp4

Premiere version ?
Because quick google show that the problem is within the source files:
3 years ago.
https://forums.adobe.com/thread/1352273

Since adobe staff said the problem was because (at least) one broken frame within the video files;

Here’s a workaround idea, convert your problematic source to image sequence, either using AE (if you have one) or with FFMPEG.

A quick google :

TLDR : Use FFMPEG

@ Hanna :

Edit: (i mistakenly read your reply, here’s the edit response)

The workflow can be applied easily full scene, no need to track unnecessary/unaffected frame.
Why bother to track the whole scene?

I’ve no idea with you saying “1 big trick on mocha to do tracking then remove”.
I use Mocha, of course i do track and remove.
