Gamer Skillz: Hard Burning Subtitles into Videos (Free tools)

[00:07] [Music]

[00:36] hi I'm dr. James welcome to another

[00:39] gamer skills video the topic today is

[00:41] how to heartburn subtitles into a video

[00:44] file you'll need to have a copy of

[00:45] ffmpeg on your system a video file with

[00:49] embedded subtitles and for the demo

[00:52] today I'm using a bot while for several

[00:55] containers that natively embed subtitles

[00:57] including Bob's which are really mpegs

[01:00] MK b's Petroski files etc there are a

[01:03] variety of reasons that you might want

[01:05] to heartburn subtitles first you can

[01:07] guarantee that they'll be displayed

[01:08] subtitles can be finicky in terms of

[01:11] getting them to show up second you can

[01:13] guarantee that the subtitles are visible

[01:15] and in the right format third you can

[01:17] decrease the number of files that have

[01:18] to be transmitted and stored as I said

[01:20] earlier we're gonna use a bob file for

[01:22] our demo today this is how a DV decodes

[01:26] the MPEG file to display in your machine

[01:28] most of the time you'll see Bob files

[01:30] divided into one gigabyte legs you could

[01:35] write a script that would individually

[01:36] burn the subtitles and to appropriate

[01:38] Bob's but I like to combine the Bob's it

[01:41] also has some secondary benefits such as

[01:43] decreasing the final size of the files

[01:45] that'll show you below and making it

[01:47] easier to code in person there are

[01:50] several ways to concatenate the bob

[01:52] files one method uses the same technique

[01:55] that was used to combine the mp3 files

[01:57] shown in the gamer skills video on

[01:58] getting mp3 files into audible you can

[02:02] also run a program called rip Bob and

[02:03] we'll talk about replied in another

[02:05] video the download link is shown below

[02:07] in my comments area let's look at the

[02:10] script in a little more detail that I'm

[02:11] gonna use today to hard burn the

[02:13] subtitles the script is consist of just

[02:16] two lines of code the first takes the

[02:18] action the second waits for the user to

[02:20] acknowledge the work is complete looking

[02:22] at that first line in more detail though

[02:23] the first portion identifies all of the

[02:26] file types of interest and then calls

[02:28] ffmpeg to take a particular action

[02:31] in this case we're using valve files in

[02:34] the second portion we tell ffmpeg to

[02:37] take the first video stream in the first

[02:39] subtitle stream and overlay them that is

[02:41] burn them into the same video stream the

[02:43] first audio stream is also mapped back

[02:45] in in the final section we tell ffmpeg

[02:48] to synchronize the audio and video

[02:50] portions of the file 1,000 times per

[02:52] second and that the target is for use in

[02:55] a DVD in particular in its movie that

[02:59] establishes a number of characteristics

[03:00] including minimal bitrate frames per

[03:02] second etc of course you can set all

[03:05] those parameters one at a time but it

[03:07] just makes it easier to use this target

[03:09] finally we tell ffmpeg that the output

[03:13] file is MPEG and that the file should be

[03:15] assigned the same names as the original

[03:18] input Bob and placed in the new folders

[03:20] new files folder you can run the script

[03:24] shown in a number of ways you can just

[03:25] double click on it from the Explorer and

[03:27] let it run you can open a command

[03:30] console and run the batch file from its

[03:32] location one useful trick is to

[03:36] right-click on the batch file and select

[03:39] edit to bring up the open file in text

[03:41] editor so this is for when you want to

[03:44] modify those batch bugs yourself I

[03:46] learned this trick from the doom 9 forum

[03:49] you can see that I use a subfolder

[03:51] called new files to put the translator

[03:52] folders in - and that's just a good

[03:54] practice to make produced file it's

[03:56] easier to find and prevent similar

[03:58] sounding files from be confused in your

[04:00] work plan

[04:01] no matter which way you choose to do it

[04:03] in just a few minutes you'll have your

[04:05] completed file with the subtitles part

[04:06] again there are a few more things to

[04:10] point out first notice that a produce

[04:11] file is smaller than the original well

[04:15] that's it for today a relatively short

[04:17] lesson if you enjoyed this video though

[04:21] thank you so much for watching that's

[04:24] all for today
