Batch embed .SRT files in MP4 container

[baglio]

Hello everyone.

As the title said, I'm looking for some way to automatically embed .SRT subs in their respective Video files.
The subtitles files are already in my possession, and I've named them properly (same name of video files).

What I used to do is to insert them one by one using Subler, it works, but sometimes happens that I have many files and it's really annoying.

Is there any OSX software which can help me out?

Thank in advance for your advice!

SublerCLI can do this with some shell scripting
download SublerCLI from the same place as Subler
put it in /usr/local/bin

the attached file "subadder.command" is a shell script that will take a folder of mp4 and srt movies and combine them (if they have the same name)
open the .command file in a text editor to see what it is doing...
and if it won't run for you do this....
open a terminal window
type chmod +x
then a space
then drag the .command file in and now it will run for you.
TEST ON A NON IMPORTANT FILE FIRST and then if you're happy..go for it on the rest!
cheers

Fascinating!

It works! I wasn't aware about this alternative version of subler which can runs commands.
Did you make this command? It's very impressive.

The only thing I've noticed is that the subtitles "meta" which are embedded have an unspecified language; also every files end to have as meta name: MY_SUBS.

Although this, it was REALLY HELPFUL!

Many thanks!

yep i wrote the command.
if you open the .command with textedit (set to plain text) and edit the line that starts with
SublerCLI

there are settings in there that were just guesses on my part so the -metadata "Name:MY_SUBS" can be changed there (or just deleted)
and also the -language i guessed as eng for english (for me) but i'm unsure of what quicktime/ps3 etc is expecting in that bit!
when you've done just save the file (and make sure it doesn't get .txt at the end)
just play around and post back here so i learn something!
cheers

Well, I think you can only teach me

Anyway... after experimenting for a while I came up with this:

#! /bin/sh
echo drag folder with video and srt files in
echo for each language the subs MUST have the following pre-extensions: !!
echo ENGLISH: .en example mysubs.en.srt
echo ITALIAN: .it example mysubs.it.srt
read thefolder
cd "$thefolder"
for i in *.m4v and for i in *.mp4
do
subname=`basename "$i"|rev|cut -c 5-|rev`
SublerCLI -source "$subname.en".srt -language English -dest "$i" |
subname=`basename "$i"|rev|cut -c 5-|rev`
SublerCLI -source "$subname.it".srt -language Italian -dest "$i" 
done
clear
echo all done. Your subs are in the video files

Since my files are .m4v and I use to embed both Italian and English subtitles I've edited a couple of things...
I personally tried it and it works, but again... if everyone wants to give it a try please test first on non-important files.

Also, can you please explain me this part of the code?

subname=`basename "$i"|rev|cut -c 5-|rev`

Thank you very much! I really appreciate!

[jamiep]

subname=`basename "$i"|rev|cut -c 5-|rev`

is a way of getting the name of the movie but without the ".suffix" at the end
ie
thingy.avi
becomes
thingy

it basically does this
subname is the name of our "variable" whaere we want to store the information we want
then the ` means "the result of everything inside the ` signs
basename "$i" this gets the name of the file from the full path ie /users/me/folder1/myfilm.avi gives just myfilm.avi
then the | means do the next thing as well
rev reverses the string so myfilm.avi is iva.mlifym
cut -c 5- means cut from the 5th character so that gives mlifym
rev reverses it again to myfilm

there is a much shorter way of doing it involving {...} type things but i can never remember it whereas the step by step approach has stuck in my head!

you shouldn't need the second subname=`basename "$i"|rev|cut -c 5-|rev`
line because once it is "set" it doesn't become "unset" until YOU reset it or the program quits.

great hacking on the code I'll have that back thankyou very much!
all the best

hey guys, I found this thread very useful. I was wondering what I would need to adjust in the code to get this to work with h264 mov files.

I'm not much a programmer, but I was able to get the code to work with a folder of 50 mp4 files. I tried it on a batch of mov files and it didn't work. I thought changing everything in the code that said "mp4" to "mov" would do it, but there must be something else going on that I don't see.

any help would be appreciated.

Thanks!

Does the MOV container actually allow for embedded subtitle streams?

If so, the subtitles may need to be converted to a different format, and/or muxed into the video in a different way. (Naturally, I haven't done much work with MOVs at all, so... yeah. )

[brobeans]

yeah they do allow the SRT files to be embedded. I can add them 1 at a time and it works. Just wasn't able to get the script to work for batches.

Hi pal. I'm not sure but I think it's just a matter of substitute the extension inside the script:

for i in *.m4v and for i in *.mp4

Will become

for i in *.m4v and for i in *.MOV

or

for i in *.MOV and for i in *.mp4

Be sure to test it out before batch your important files. Let me know!

I had to register and THANK each of you in this thread. I had hundreds of TV shows needing subtitles embedded and I KNEW there had to be a better way than one-at-a-time in Subler. I'm so glad I found this thread AND this forum. Thanks, again and Happy New Year!

Happy new year to you buddy. I'm glad you've found this thread useful. If this could help you further, I figured out that now this is also possible through the GUI.

Be sure to have both MP4s and SRTs files in the same directory and with the same name; you can even append the initial of the subtitle language: e.g. .it; .en; .sp and so.
Then simply open the Subler queue, drag the MP4s you wish to add the subtitles to, tweak your scraper preferences and start.

Now you should have all your queued files with embedded subs.
