You'll now see the video in the upper-left corner of the screen, and in the upper-right, you'll see the audio for that video Then, open the video you'd like to subtitle by clicking the Video menu and then "Open Video." To begin creating subtitles in Aegisub first open the program. Once created, the caption file can be easily attached to any of your videos in Warpwire. ![]() With a bit of time and effort, you can create an accurate, high quality caption file for your video. Aegisub allows you to load a video and caption it line by line. Aegisub is a free, open-source program for creating subtitles. VTT closed caption file, you can create captions yourself.

Just for perspective, this is my manual system for figuring out time code shifts before finding this calculator. Everything else like this on the web seems to require laborious excel macros. There is an option to donate if you like his freeware, which I did. So in example above, the amount the subtitle needs to shift is 00:00:22:16, but if you are using something like AegiSub which requires giving the last position in miliseconds, look at the number inside bracket and the calculation is done for you– in this example 22:16 = 22.666 (or 22.67 rounded up). In my original inquiry, I was asking about shifting individual blocks within an SRT after they have become mis-aligned, and since in such cases the misalignment is often backward or forward, this calculation gets you to how much you need to shift accurately (and quickly, I was doing the calculation manually, following Stan Jones helpful answer above).Ģ) Converts frames in the last position (00:00:00: 00) to miliseconds. I followed Stan's advice and did the shifting in AegiSub (which is similar to Subtitle Editor) and after I changed the units to frames, was able to do a precise shift.įound this excellent online time code calculator designed by Michael Cinquin.ġ) Calculates the exact time code difference between two time code points. I have attached a screenshot– bottom row is the correct subtitle position (but that version has a gap at beginning due to adding extra audio), middle row is with 0.51, top rop is with 0.50. So looks like that fractional difference cannot be matched/resolved using Aegisub. Then I tried doing 00:00:09.50 (Aegisub didn't allow 3 decimal points) and that was a fraction behind the correct point. I tried that and the resulting SRT was a fraction forward of the correct point (looks like 24% of a Premiere frame). So total shift would be 00:00:09.51 in Aegisub. That means adding 9 seconds and then a certain number of miliseconds (AegiSub shows only up to two digits by the way, even if it is mili), something along the range 1:09 - 0.87 I'm detailing the results here, in case it's helpful to other users. I looked online for calculators that do the conversion, but websites like this one /timecode-calculator/ give you only a total number of frames. xx format showing at end of SRT time code isn't in the same format/mathematics as the :yy format showing at the end of the subtitle(.xx seems to go up to 99 while :yy goes up to :30), I don't have a way of doing the math for how much it should move. When I open the file in AegiSub the time codes are in SRT format, which means that the errant subtitle is showing as 00:01:03.87. I export the Subtitle as an SRT (File>Export>Captions) and then move to AegiSub where I know there is option to shift a group of susbtitles and have time code change. In Premiere I can see that the first mis-aligned subitle needs to move to 00:01:13:09 (I will shift all subtitles at one go, but this first one is the marker). A little bit of extra audio was inserted into beginning of film, but there's no way to drag/extend the subtitle track backward to fill in that gap (and even if I did, the actual time codes would not change to the right position) Now that all the subtitles have been manually placed, if I wanted to shift them, there's no way to grab all the subtitles and drag them forward Subtitle track was created using File>New>Captions>Open Captions and then placing that into a video track I can't do it in Premiere itself for the following reasons: I need to shift a set of time codes in an SRT file (using Aegisub Editor) to fix a mis-alignment within Premiere (Open Captions Subtitle file). ![]()
