New Application trimsrt trims and shifts srt subtitle file based on range of frames

[xekon]

I made a couple of posts and searched everywhere I could think of for an application that would take an srt subtitle file and trim/shift it based on a range of frames for situations where you do something like this in Avisynth:
A = NicAC3Source("E:\AviSynth\job.ac3")
V = FFVideoSource("E:\AviSynth\job.mkv")
AudioDub(V, A)
AlignedSplice(Trim(2832, 16727), Trim(16896, 31295))

I was unable to find an application that would do this via command line, so I wrote this program.

The Source code is included, I release it under the GPL.

If you find any problems please report them. If you know c++ and fix a problem or extend the application, please share.

I just started using Avisynth a couple of weeks ago, and I just wrote this application over the last couple days.

So far it has worked perfectly for me, but consider it to be in Beta testing stage.

most of my testing has been using 2 frame ranges (2832,16727,16896,31295), but it should accept as many frame ranges as you need.

Usage is -i <file> -f <fps> -t <frames>

omitting -f <fps> assumes an fps of 23.976024

trimsrt -i 004.srt -t 2832,16727,16896,31295

trimsrt -i 004.srt -f 29.97 -t 2832,16727,16896,31295

other format conversion to srt tip:
To convert SUB/IDX or .SUP to .SRT. I recommend using Subtitle Edit: http://forum.doom9.org/showthread.php?t=162721

Thanks, any chance you will add support for .ass subtitles?

[b66pak]

thanks a lot...

I have not worked with that format but after quickly checking I see that it is also text based so it should be easy enough to add support for.

I will look into it, and see about adding support for that.

Thanks.. You can easily convert a .srt subtitle to .ass subtitle format with Aegisub if you don't have any .ass files lying around...

Have to say I'm quite surprised you haven't touch .ass subtitles before, it's a superior subtitle format compared to srt.

Does anyone still use this tool? It sounds exactly like something I'd love to use, unfortunately, the cuts are never correct, and I don't know why.
I noticed that no matter what fps value I entered (-f 25 or -f 50, PAL region), the resulting srt file were exactly the same. What am I missing here?

[StainlessS]

Dont know but just a daft suggestion, try eg -f 25.0 or -f 50.0 ie with .0

[duedel]

Thanks, your quick :)
Tried it, same result :(

[StainlessS]

Give the exact command that fails please.

[xekon]

Everything I have used it with so far is 23.976 fps.

This was the initial release and I may possibly still have the fps value hard coded in the code.

Unfortunately I am too busy to look at it now, but the source code trimsrt.cpp file was included in the zip, if anyone wants to make updates before I get the time to, feel free.

[StainlessS]

xekon, fps is defaulted to 23.976 FPS and then updated if -f flag used, but not used at all after that, ,seems to use 23.976 for everything.
I'll try to fix it but really dislike the CPP style lib funcs.

I'll try to fix it but really dislike the CPP style lib funcs.

This would be beyond awesome!! Can't wait :thanks:

Ok, made changes but getting error

I never really used CPP libraries for at least 20 years (and only a little bit back then), anybody suggest what is required, some kind of cast ?

EDIT: xekon, what was it originally compiled with ?

[StainlessS]

Tried with VS6 originally, re-tried with VS2008 and still same error.
What was it originally compiled with ? (non modded source produces error too).

[duedel]

I really wish I could help, StainlessS.
Let's hope xekon sees this.

[StainlessS]

OK, managed to get it to compile by adding myFileb.c_str() stuff in blue.

VS2008 compiles OK, but VS6 produces Linker errors about "__security_check_cookie", no idea what that is.

Anyways, heres the fixed (I hope) version together with original source.

EDIT:

libcp.lib(xlocale.obj) : error LNK2001: unresolved external symbol @__security_check_cookie@4

[duedel]

Yep, working fine now. Again, thank you so much!

[StainlessS]

OK, I'll attach the zip here.

EDIT: No runtimes required.

[xekon]

Thanks for the update StainlessS! I figured i must forgot to swap out the hard coded values for the variable, strange about those compiler problems, I believe i originally used VS2008, but it could have been VS2010 i really cant remember. Need to remember to put stuff like that in the comments :)
