    Recommend a frame-accurate smart video cutter/trimmer

    Hi, I want to cut/trim the commercials out of .ts and .mp4 files that I have DVR'd. It needs to be smart (only re-encoding the frames between the cut-point and the next key-frame). The closest that I can find that meets this criteria is: SmartCutter - but it crashes (costs £ 50 but has not...

    QuickTime Player can't open .mp4 from external HD

    I bought an external hard drive to back up my video files. After copying I noticed certain video files will not play when I open them from the external drive, but they will open from my computer. I get the message "QuickTime Player can't open ____.mp4". Quicktime is my default player, and the...

    How to extract video from mkv?

    Am I missing any essential app for extracting workable video from MKV files? I.e. something I can either recut or cut to gifs? Currently I use AnyMP4 (free, App Store) to cut and convert to MP4, or Lossless Cut (free, GitHub) if I want to cut first, then convert. Both are terribly bad with the...

    iMovie MP4 file space

    Relatively new to iMovies, I created two MP4 files by editing digital camera home videos using iMovie. I had read that each hour of video translates into about 1GB of storage space as an MP4 file (and possibly up to 2GB per hour if HD). The MP4 files created (50 minutes & 93 minutes in length)...

    D/L MP4 Video Has No Sound?

    In the last few weeks I've been having a problem with downloaded MP4 video files. I can play them and cast them directly to my HT via Chromecast just fine, but after downloading them to my computer, they have no audio. The video is perfect, but when I try to convert them, the conversion programs...

    MP4 preview hangs in Finder?

    I've found that with the last 3 or so betas for 10.13 and the final release that MP4 preview in Finder has been hanging consistently and requires a Force Quit / restart of Finder. Apple has been silent on the issue with me for over two months even though I keep pestering them. Has anyone else...

    Batch convert MKV to MP4 with subtitles

    I know Handbrake can convert MKV files with subtitles to MP4/M4V. You select the MKV file, go to subtitles, and choose the english version. Pretty simple. But how would I do this with multiple MKV files, without having to keep an eye when one is done, so that I can load the next file. I...

    Issues with Handbrake fps conversion

    Hi folks, I'm having an issue with Handbrake just now to convert files (.avi, .mkv, .mpeg, .wmv to mp4). A few days back with .mkv files I was having up to ~550fps conversion rate, but now for the same file type I seem to be also getting ~72fps. I've updated the program to see if this is the...

    Downloaded, then deleted video files (mp4) - how to make sure I'm safe?

    So I'm usually careful, but got bit drunk and ended up downloading some naughty mp4 video files from direct download file upload site. And of course made copies and put them on external hard drive. Come next day and hangover, cursed myself, deleted all videos from Mac and external hard drive...

    iOS 10.2 Videos in 3rd Party App Don't play

    I've been using the atomic web browser for years to watch downloaded MP4 videos. Since updating to iOS 10.2, none of the videos play. After selecting a video, the first frame will show up, but clicking on the play triangle won't do anything. Can anyone offer any help? Thanks!

    MP4 and USB and Apple TV 4

    I have a bunch of videos and movies stored on USB from a variety of original sources. Is Apple TV 4 capable of playing MP4 files? What's the process of getting them to play on the device? Would a different set top box better? Is Apple TV likely to be updated to Apple TV 5 soon? Thanks in...

    iTunes (12.4.1.6) suddenly won't import MP4 files

    Hi folks, I'm trying to import an MP4 into my iTunes library after running it through Handbrake (I always use the same settings) like I have since time immemorial, and suddenly it won't accept the files. I've tried it with a few different MP4 files and no luck. I've tried dragging them into the...

    4K Video freezes iMovie & system

    Has anyone else had an issue where the 4K from your iPhone 6S or SE completely locks up iMovie? I have a mid-2014 Mac 15" with decent specs (benchmarks from Geekbench here) but when I go to edit or try to play the MOV file from my iPhone, I just get the spinning pinwheel and the entire program...
