6/2/2023 0 Comments Rotate mp4 mp4tools![]() If you are updating from a pre-3.5.x version, the preferences have been updated and as a result you will need to re-enter your presets, registration code and other preferences. It has been tested on a MacBook Pro and a Mac Pro with no known issues. MP4tools is Intel-only (64-bit) and requires Mac OS X 10.9.x or later. If you decide to register, download the software using the link below, and then follow these registration instructions. This will get you a registration code that unlocks all of the suite apps. When registering, you have the option of registering for just MP4tools, or you can choose to register for the VIDEOtoolbox suite of applications for less than the cost of registering two applications. You should probably consider this software as being sold "as is", so test thoroughly to see if you think you’re getting your moneys worth before registering. Bugs still exist which may or may not get fixed and there are known issues and probably some unknown issues :-). Note, that the output of the registered and unregistered versions of MP4tools will be identical, so you can thoroughly test MP4tools before you decide to support it’s development. Hopefully you will consider the usefulness of this software to be worth the price of a meal at McDonald's :-). The above limitations will disappear if you register the software ($5.99 - the price of a Big Mac dinner around here). ![]() You may only run 1 job at a time, so you can't take advantage of the queue and batch capabilities of MP4tools.A “nag” window will appear every time you load a new file. ![]() In case your video contains stereo audio, this is obviously not switched, so in case you want the sound to match with video rotation (180°), you need to switch the left and right channels.MP4tools is technically trialware, though in reality, the unregistered version has nearly complete functionality with two minor exceptions: in the two rows before it the rotation matrix is stored.in between there should be an sign (HEX 40).some rows above (for my files mostly 9, sometimes 12) you should see trak.\tkhd.open mp4 with hex editor and search for vide to find the metadata of the video track.To get true lossless rotation, I couldn't find a solution, so I grabbed a hex editor (eg HxD) and analyzed the rotated video files. I would prefer to just edit the flag (like exiftool is doing it for all kinds of metadata, but can't do rotate in videos) instead of streaming the content into a new container, also for faster processing (all videos are on NAS). mp4 files in notepad to identify the rotate flag / matrix, but without luck, just jibberish. ![]() I compared ffmpeg rotate=0 and rotate=90. *Compatible Brands : isom, iso2, avc1, mp41 displaymatrix: rotation of 90.00 degreesĮxiftool input.mp4 =ExifTool Version Number : 10.87 = equal attributesįfprobe input.mp4 *Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '.\input.mp4': Attached is before and after metadata from ffprobe and exifer.Īn additional odd finding is the ffmpeg rotate=90 command makes a ccw rotation, which in ffprobe is (cw) 270° in metadata, but (ccw)90° in displaymatrix side data. My problem with those solutions is that even though it copies most of the metadata, some parts are lost, and the file is 700kb smaller. Many similar questions exist, most answers suggest using ffmpeg -i input.mp4 -map_metadata 0 -metadata:s:v rotate=90 -codec copy output.mp4 I just want to change the rotation flag in a.
