If you can script yourself, all you need to do is call FFmpeg repeatedly: ffmpeg -ss [start-time] -i input.mp4 -c copy -t [clip-time] output.mp4 Here, start and clip times can be in the form HH:MM:SS.mmmm, or just in seconds. To give you a rough idea how that'd look like in Ruby, see this Gist of mine. It contains a script that takes an edit list, a ...

FFMpeg has an option to modify the aspect ratio of a video file without actually modifying the video, see http://www.ffmpeg.org/ffmpeg-all.html#Video-Options For example, in your case, the desired aspect ratio is 720 / 480 = 1.5 (3:2) (which is NOT 4:3, it should be 540 in that case) So your command line may look like: ffmpeg -i input_file.avi -c copy -...

Yes. M4V is a slight extension to the MP4 container format. M4V is Apple's version, which adds optional DRM-encryption. So if the video is DRM-protected (i.e. came from the iTunes store) it should stay as m4v (and will open by default in iTunes). If it's not, it can be used with either extension, and many players will be happy either way. By default, .m4v ...

This is a well-known bug when exporting to H.264. Unfortunately, I'm not clever enough to understand why this happens, but it's a side effect of using the codec. I'll keep looking for an explanation I understand, however I wanted to get this answer out there. As a workaround for now, I suggest making a quick little eyeball adjustment to the comp's colour ...

I think the simplest way to this is to use MP4Box. ./MP4Box -add file1.mp4 -cat file2.mp4 -cat file3.mp4 output.mp4

No, the display port on your macbook pro is output only. You may be able to use your camcorder as a webcam if it is capable of streaming video over USB or Firewire, though.

All anyone might be able to say is that there are no known holes in the various players. (I don't know if that's true, just that it's impossible to know that there are no undiscovered bugs in a complex piece of code.) H.264 streams are complex enough to have lots of corner cases. They're parsed with speed-optimized code written in C and assembly. You're ...

ffmpeg, a free multi-platform command-line tool, can do this. Use the volumedetect and EBUR filters on each of the files ffmpeg -i input.mov -af volumedetect,ebur128 -f null - 2> input.log This will produce a log file with the initial lines looking like this: [Parsed_ebur128_1 @ 0000000002d42400] t: 12.7 M: -32.7 S: -32.7 I: -30.7 LUFS ...

Update: The VLC TS is malformed. First run ffmpeg -i vlc-output.ts -c copy ffmpeg-output.ts and then ffmpeg -i ffmpeg-output.ts -c copy working.mp4 The main thing that looks off is the timebase 1000k tbn. Try ffmpeg -i vlc-output.ts -c copy -video_track_timescale 90k car-free\ tourism.mp4

I also have an idea, if your sequence and titles are too complicated you can save a copy of your project and then import a sequence from it to the main project. It's best possible solution to copy title I've found with motion titles templates.

I also bumped into this issue and couldn't find a way to create a true copy of a text layer that contains effects, etc. However, there is a way around this, it still adds 1 step to the process, but it's better than most solutions I found. So, duplicate your title, rename then go to the original title, choose it on the timeline, copy it. Then go back to the ...

Duplicate both your Title and your sequence, call one sequence V1...and the other V2, then take your title and call it Title V1 and title V2...then replace the title in sequence 2 with V2, then from that point on any changes made within the V1 side will not affect V2 and vise versa.

AVIdemux can do that when encoding, but i cannot remember if it allows you to do that when you chose to copy the stream without reencoding (you don't want to reencode, since it will not only be time consuming, but also lossy). If you are willing to change it from AVI to MKV (VLC and most other players will have no problem playing it) you can do that with ...

...FFMPEG worked, it was a steep learning curve in terms of getting it to work in my environment and, took me a few days to learn how to code in Bash Scripts Shell based, but in the end very happy with the results and it's integration with both Macs and my Unix server.

Be aware that you are not changing anything. If I call you Bob, you are still Jac and even then you are probably posting under a different name. If you have software that naively trusts the filename instead of examining the actual binary headers of the file, this can work for you. If the actual format or encoding is wrong then no name change will fix that. ...

Yes, this simple conversion should work fine. Both files are technically mp4 files anyways. Notably, certain older Apple products, like older versions of appleTV for example, require it to be in m4v format so don't forget to switch it back if you're switching between a Mac and a PC if you are using older mac products. By default, m4v files will always open ...

I was seeing the same thing. Exported video when played in QT was washed out compared to what my preview was in Premiere. When I looked at the same rendered file in VLC it matched. so evidently the problem was in QT. I opened pref and found a dialog box that said. " Enable Final Cut Studio color compatibility. When enabled video is not displayed using ...

I can recommend Adapter. It is a Wrapper for the ffmpeg package and does its job pretty well. Because of its easy UI. You could also use ffmpeg directly via macports, but I think that Adapter is far easier to control.

For online delivery and viewing on laptops/tablets, 720P should be sufficient for capturing the entire sheet in a legible way, but resolution isn't the only factor to consider... A 1080P camera would capture higher-resolution images, but a 1-hr lecture at that size would probably result in a file size around 1GB. Assuming the intended delivery is online, ...

You are going to need to use; preferably After Effects to do this. You could also do it in Premiere; but AE is the way to go, because you can use the tracking feature to auto follow objects; combined with a custom mask (with a blur filter applied). Other than that your options will be limited. I believe Adobe CC allows a 30 day free trial; and it's ...

The GIMP has a GIF Animation Package that can convert MP4 to gif. You can just use the Split Video into Frames function, which will split each frame into a layer in GIMP. Then when you Save As, select .gif and choose Save as Animation. Photoshop has a similar function, but I haven't used it for a while now.

1st, make sure you don't have any equipment or 3rd party programs that interfere with the audio on your computer because, more often than not, it is a problem with that instead of the audio on the computer itself. I actually asked a similar question (which is specific to your question) about a third party program messing with Ableton (same as with Premiere)...

I was encountering audio sync issues when trying to do this with Avidemux, but I came upon a two-step process that keeps the audio in sync: Concatenate files using MKVToolNix (I used version 7.4.0 for Mac). This results in a Matroska video (.mkv) file. Remux the .mkv file to MP4 format using Avidemux (I used verison 2.6 for Mac). I chose the MP4v2muxer ...

You could create a droplet in compressor. Unfortunately, your options for destination folder are limited by this method to either source, desktop, cluster storage, or your movie folder. Since you don't want your watch folder endlessly copying movies, "source" is a bad choice, and you probably don't have cluster storage, so as long as you're ok with your ...

If you have a Mac, download "Cam Twist." It offers reasonable live keying, and it can even put you as picture in picture. If you use the right browser, I.e. Firefox with the Google Hangouts plugin necessary for hangouts, "Camtwist" will just be an option in the list of cameras. Download it here.

The good news is I didn't just overlook something. Transcoding .WMV to .MOV is a real problem. The bad news is that it cost me $29 to solve it. I purchased the "Player Pro" license for Flip4Mac by Telestream after reading this support article by Apple.

8 cores is nice but unnecessary. Adobe products rarely utilize all the cores unless you have multiprocessing enabling, which if you don't know: multiple frames are being rendered at the same time using different cores for each frame. But even at that I doubt you could get all 8 cores on board to do that because you need more ram dedicated to each cores ...

There are two steps, broadly speaking, to rendering a project in a NLE such as Premiere. First step is for the NLE to generate the uncompressed final composite image for each output frame. This is undertaken/managed by the rendering engine of the NLE. And the second is to encode these generated images using a codec into the final video output file. For the ...

It appears that the subtitles file did not have --> but a –> with the – corresponding to the en dash that was placed in the file, which was edited by hand externally. It seems like the en dash sign was assigned to typing -- in Mac TextEdit (the functionality can be disabled in preferences).

HighPoint RocketStor RS5212 is a Thunderbolt Dock that will accept two hard drives or SSDs. I would not use FireWire for SSDs, unless you don't have USB 3.0 and you're on a budget. USB 3.0 is often fast enough to get the maximum out of your SSD, FireWire not.
