The automatic splitting seems pretty decent, but sometimes it chops a sentence awkwardly. It would be nice if I could ask substudy to include one line of dialog before or after the "target" line for context.

Ideally, as separate "columns" in the csv output, so I can style them differently in Anki. :)

There's a good chance that I could reuse some code from https://github.com/kiddsoftware/srscollector/tree/master/extras/anki

Hi! I'm getting this error using the export function. I get it with both the binary release and installing via cargo install.

There are several segments with the time period that it complains about.

It doesn't seem to be refering to any times in jp-1.srt but here is that general area:

125
00:07:31,520 --> 00:07:33,180
猫動画が人気あるのか

Fix: After manually merging the segments in en-1.srt that started at the same time, this issue went away and everything worked as expected.

In particular, make sure we can handle async Commands.

Great tool, thank you for your efforts.

I do wish for one feature especially though, it's almost a deal-breaker, and that's the ability to adjust the padding of subtitle times through an argument when generating Anki cards through substudy.

It seems to me, and correct me if I'm wrong, but it certainly seems that the times are being automatically padded by substudy, meaning there is extra time added on both the start and the end.

This might be a sensible default, as it's presumably better to have a little too much of what's said, than too little, but I have some pretty nicely timed subtitles, and it would be great to be able to prevent this padding from taking place, even if it's not the default.

I've tried looking through the source, but tbh, I'm not a great programmer, I'm actually integrating substudy into some scripts, but I've been looking at a lot of python and POSIX sh for the last few years, not so much C-like languages, and I'm totally unfamiliar with Rust. It seems a lot isn't commented, so I find my eyes glazing over and my brain shutting down when I tried to figure stuff out in the source myself.

Even if this isn't what's happening, perhaps a command line argument to reduce or increase padding would be good.

I'd try to implement it myself as I'm sure it's rather simple, but for the reasons I stated earlier, I'm pretty much at the mercy of your (or some other kind soul's) benevolence.

When testing a new video & subtitle file, I run substudy a couple times. I have to manually delete the output dir each time, or else substudy quits. It would be nice if it could prompt me to overwrite if I want to continue anyway. Or maybe a --force option, if you want to conform to Unix-y expectations and avoid interactive prompts.

It would be nice to provide link to youtube video and languages, and substudy would download it with subs and create anki deck out of it.

Maybe it should be created on top of substudy? What do you think?

I'm trying substudy out on another file, and this one has timing issues that I thought I had fixed, but apparently didn't. So that means I have to try fixing the timing again, then hope that this time I got it right, then wait for substudy to process the entire video again, then re-import into Anki, before I can check if it's okay.

I wish there was a "test" feature of substudy, so that I could check the first 2 or 5 minutes of the video for timing issues, before "committing" to processing the entire video.

As seen in issue #25, substudy's error messages for missing files (and failed ffmpeg runs) are pretty useless. The right thing to do here is to create wrapper errors using error-chain and use quick_run!.

Seems if you use a format (mp4) other then MKV you get this error "MissingFieldError("codec_name")". However a simple convert works in ffmpeg. I wasn't sure if there is another way to get around this. I may try my hand at a PR on this, but have never done Rust ;) Great program btw, much easier then sub2srs

This should support our standard export functions, and it will probably be based on Electron.

It would be nice to have graphic interface sometime in the future, although I know there is no clear solution to this problem now, so maybe just keep this issue open until there is a light, cross-platform solution in the future.

I want to see if ReasonML is a good choice for a GUI layer.

• Build a "Hello, world" app.
• Display video.
• Convert old server to generate basic JSON needed for GUI.
• Figure out how to open a JSON file using the GUI (still very primitive).
• Port over CSS.
• Implement automatic window layout and subtitle-only scrolling.
• Implement "scroll to playing subtitle".

Using the list track command produces an error when querying a mkv file created by ogmrip. Had to use ogmrip because of copy protection.

substudy list tracks CM6-0E-UT3.2_DES.mkv
MissingFieldError("tags")

Using the command mkvinfo, I can see the track information and extract the appropriate sub-title track.

mkvinfo CM6-0E-UT3.2_DES.mkv

| + Track number: 4 (track ID for mkvmerge & mkvextract: 3)

any subsequent reference to tracks however fails on the tags metadata.

substudy export tracks CM6-0E-UT3.2_DES.mkv it.srt
MissingFieldError("tags")

We have several prototypes of this, but I want to rebuild the Elm-based version using ReasonML+React and integrate it with an Electron GUI.

If the subtitles are significantly longer than the video, it would be nice if substudy printed a warning message letting the user know about the potential problem.

When I run, substudy combine episode_01_01.es.srt episode_01_01.en.srt > episode_01_01.bilingual.srt

Nothing happens. If I drop the word substudy from the above, I get "Usage: combine Filel OP file2" as an error.

If I run substudy export csv episode_01_01.mkv episode_01_01.es.srt episode_01_01.en.srt then I get "MissingFieldError("streams")"

If I run that code wthout the ">" after mkv, then I get:

https://forum.language-learners.org/viewtopic.php?f=19&t=6360&start=10 is where another person tried to help. I welcome your thoughts on where I am going wrong. I installed LinuxMint18 just to use your program, so maybe it is possible I am missing some foundational download I need before using substudy.

I have an .avi video file that has no language data. substudy list tracks myfile.avi outputs the following error: MissingFieldError("tags")

For what it's worth, here's the output from ffmpeg -i myfile.avi:

I’m getting the following error with mp3 files on substudy:

$ substudy export csv Traicionera.mp3 Traicionera_subtitles.en.srt Traicionera_subtitles.es.srt
MissingFieldError("tags")

There might need to be some flags or “tags” to process the .mp3?

It takes a while before substudy quits with an error about the output directory already existing. It would be nice if it checked that first and exited immediately.

@Arthaey has suggested a couple of command-line flags that I agree are good ideas (despite my general bias against them). These can be added much more easily if we switch argument parsing to clap. I'll try to take a look at this.

We're only printing out the "top-level" error message and not the root cause. Fix in both the regular app and in substudy-backend.

I'd like to be able to provide my own HTML template for the output of the export review command.

My personal interest in this is that I'd like to be able to use my own audio player to play the files rather than the built in audio element (for better sound playback control) and also potentially having a side-by-side layout rather than an interlinear one.

Trying to package this program for nixos NixOS/nixpkgs#48139, should I use substudy_v0.4.5 as the latest release ?

I'm trying to export my mkv to csv using the given command substudy export csv episode_07_01.mkv \ episode_07_01.fr.srt episode_07_01.en.srt but I can't seem to get it working. I get ExpectedError("Number", "-99").

I'm having no problems using the combine code for the bilingual subtitles. I just can't seem to get the export working for the life of me..

Is there documentation about how to use subtitles-rs. I cannot find it. I downloaded the binary but I cannot see any user documenation either online or within the tool. Please help.

First of all thanks for the amazing tool. It's super nice to be able to combine both subtitles.

Ideally I would like to be able to select words from a subtitlte and act on them like https://animelon.com/video/594e558522477e0e27f1f035 does

I think you have a similar project with #22 .
A more short term goal could be, in the srt file, to map each words to their translation (in combined mode) via different colors /underline where that makes sense.

It's time for (I hope) one last proof of concept for the GUI. To do this, we would need to implement:

• koute/stdweb#62 Add video support to stdweb.
• Ditto for yew.
• Build a video player which shows time.
• Load and display subtitles.
• Figure out what to implement next.

This would make it easier for people to get started.

Platforms we need to support:

• Linux (using musl-libc)
• Mac
• Windows

These are generated by the aeneas alignment tool. I'm not sure how to best handle them, but at least we shouldn't error out.

I ran substudy export review for the first time, and wondered if it was working because it showed no progress indicator, or even a "Now exporting" status message. An indicator other than my CPU spiking would be cool. :)

The default algorithm for splitting up audio works well enough for TV shows, where splitting up a sentence isn't really the end of the world.

For my weaker languages, I had the idea to use substudy with songs instead of TV. But it's going to be really weird and annoying to split up lyrics that way, especially when they're already "bite-sized".

So here I am, asking for yet another option to be added to substudy. ;)

An odd error.

Cannot truncate time period Period { begin: 610.839, end: 611.874 } at 610.839

The first part of the file is.

Forse dovremmo tornare indietro.

I've compared this to other ones which have been successful and it doesn't look any different. So, is it possible the problem is with the mpv file output by ogmrip ?

• I'd love to be able to provide three or more input subtitles each in a different language.
• I'd also love to have a "language agnostic" mode where no one language is designated as the "native" language and that no one language is designated as the "foreign" language. No language is given priority over another one in any way other than the order they are specified (formatting, etc.).
• And I'd like to be able to optionally pair a media file with each of the input subtitles. (Meaning the possibility of not using a media file at all, only pairing the texts without audio at all, and also the possibility of using a media file for each language, so that audio can be listened to in any of the languages.)

I would like to use this in order to output an HTML file with a table of three or more columns of languages with media for each cell (all columns/languages, and all rows/segments). As a reference, this is what I'm after: http://emichaelsphoto.com/~aardbei/content/parallelponies/ (clicking and holding on a cell plays the associated media.)

Another simple usage scenario for being able to provide more than two subtitle files is being able to provide Japanese, hiragana, and English in order to have all three interlaced in the current format of the export review command.

This tool generated Image fields like this:

My front template has a placeholder like this:

When reviewing, instead of seeing the image as expected, I see the HTML code for the image instead.

Is there a way to make Anki display an image whose HTML code is stored as a Note field? Is this a limitation of this tool or a limitation of Anki?

I'm trying to update substudy and get it running again after a long time not using it. It used to work! On this same laptop, even, but before I'd upgraded to El Capitan.

I'm on a Mac (El Capitan 10.11.5). I ran multirust update stable and brew install cmake ffmpeg to make sure those dependencies were all up to date. No issues there.

But whether I run cargo install substudy or cargo build, I get the same error message:

I'm trying to build a csv from a youtube video with transcripts. However I get this error message.

substudy export csv Clôture_de_TEDxParis_2015_Chris_Esquerre_TEDxParis.mp4 XKqlIjZ690_0_fr.srt 9XKqlIjZ690_0_en.srt
error at 140:1: expected one of \n, \r, [0-9]

I understand that the problem is it is expecting a carrage return or newline, but in which file? And is the 140: the line number or the srt block number? (both of which look ok, btw)

9XKqlIjZ690_0_en.srt.txt
9XKqlIjZ690_0_fr.srt.txt

I tried to make flashcards from youtube video, but I get an error:

error at 2:8: expected one of `,`, `[0-9]`

Something is wrong with the subtitles?

Edit: Ok I fixed it. Apparently frame number was missing (after the time). I used different site to download the subtitles and it worked :)

The tool is great but the images are a little small for me. I guess defaulting to small images is to save on disk space but it would be great to able to select image size.
I'm not so familiar with Rust so I couldn't figure out from the code how image size is handled currently, but perhaps allowing the user to scale the input resolution by a factor of the original would be the simplest way.

This still needs a lot of experimentation and design work, but initial tests with manual decks are fairly promising.
