==========================
scripts that i might need later for transcoding

### Transcode input to av1 and transcode the audio aswell (used for teen titans)
```
#!/bin/bash
#script written by logan but typed by zombie
#optimezed for teentitans
for i in *mkv; do
av1an -i "$i" -o av1/"$(basename "$i")" -e aom -c mkvmerge --passes=2 -v "--threads=2 --cpu-used=5 --end-usage=q --cq-level=24 --enable-fwd-kf=1 --aq-mode=1 --lag-in-frames=48 --bit-depth=10 --kf-max-dist=240 --kf-min-dist=12 --enable-qm=1 --sb-size=64 --enable-keyframe-filtering=2 --arnr-strength=2 --arnr-maxframes=3 --sharpness=1 --enable-dnl-denoising=0 --denoise-noise-level=5" -a "-c:a libopus -b:a:0 128k -af aformat=channel_layouts='7.1|5.1|stereo'" --chunk-order random -m lsmash -r
done
```
for the one above it will transcode ALL the audio tracks so you might want to delete some unnessicary ones
like with teentitans there was a lossless track and a lossy one and i wanted to only transcode and keep the lossless one
so i use
```
for i in *mkv; do mkvmerge -o "$(basename "$i").balls" --audio-tracks 1 "$i"; done
```
to delete the unwanted tracks
you can use the `mkvinfo` command to get the track you want to remove
#### this one doesnt transcode the audio
```
#!/bin/bash
#script written by logan but typed by zombie
for i in *mkv; do
av1an -i "$i" -o av1/"$(basename "$i")" -e aom -c mkvmerge --passes=2 -v "--threads=2 --cpu-used=5 --end-usage=q --cq-level=24 --enable-fwd-kf=1 --aq-mode=1 --lag-in-frames=48 --bit-depth=10 --kf-max-dist=240 --kf-min-dist=12 --enable-qm=1 --sb-size=64 --enable-keyframe-filtering=2 --arnr-strength=2 --arnr-maxframes=3 --sharpness=1 --enable-dnl-denoising=0 --denoise-noise-level=5" --chunk-order random -m lsmash -r
done
```
### Transcode input to h264 and not audio (classic zombie crap version for playing on phone)
```
# create the h264 directory if it doesn't already exist
mkdir -p h264
# loop through all .mkv files in the current directory
for file in *.mkv; do
# run the ffmpeg command on the current file
ffmpeg -i "$file" -s 960x540 -c:v libx264 -preset veryslow -crf 30 -c:a copy "h264/${file%.*}.mkv"
done
```
#### single file version
```
ffmpeg -i Teen\ Titans\ S04E11.mkv -s 960x540 -c:v libx264 -preset veryslow -crf 30 -c:a copy output540pveryslow30ep11kleiner.mkv
```
