Download Quicktime Pro For Mac

I understand that H 264 is a format option. This doesn't help me. Nor does exporting in one of the existing options. File sizes are crazy huge. Over 60GB whereas it would be less than 5GB in the desired configuration (one I used to have).
What you're trying to export to is (I believe) a 32-bit QuickTime 7-era format, which has been EOL'd by Apple. So all NLE companies (including Adobe) must eventually comply by eliminating support for such a format. The only supported codecs that are allowed in the QuickTime wrapper require full 64-bit support.
you might try using mpegstreamclip and do a save as to convert an .mp4 to a quicktime with the h264 codec. Used to work. And they is to do a "save as." Goes very quickly. You're just changing the file wrapper... Here's where to get it.
Do not try and download from any other site. I once told a client to get it, and he downloaded what he thought was the program and managed to install a relatively benign virus that mucked with his internet experience.
The QuickTime format is used for many different types of audio, video andimage files (most notably, MOV/MP4 videos and HEIC/CR3 images). ExifToolextracts standard meta information and a variety of audio, video and imageparameters, as well as proprietary information written by many cameramodels. Tags with a question mark after their name are not extracted unlessthe Unknown option is set.
When writing video files, ExifTool creates both QuickTime and XMP tags bydefault, but the group may be specified to write one or the otherseparately. If no location is specified, newly created QuickTime tags areadded in the ItemListlocation if possible, otherwise inUserData, andfinally in Keys,but this order may be changed by setting the PREFERRED level of theappropriate table in the config file (seeexample.config in the full distribution for anexample). Note that some tags with the same name but different ID's mayexist in the same location, but the family 7 group names may be used todifferentiate these. ExifTool currently writes only top-level metadata inQuickTime-based files; it extracts other track-specific and timed metadata,but can not yet edit tags in these locations (with the exception oftrack-level date/time tags).
Beware that the Keys tags are actually stored inside the ItemList in thefile, so deleting the ItemList group as a block (ie. -ItemList:all=) alsodeletes Keys tags. Instead, to preserve Keys tags the ItemList tags may bedeleted individually with -QuickTime:ItemList:all=.
Alternate language tags may be accessed forItemList andKeys tags by addinga 3-character ISO 639-2 language code and an optional ISO 3166-1 alpha 2country code to the tag name (eg. "ItemList:Artist-deu" or"ItemList::Artist-deu-DE"). MostUserData tags support alanguage code, but without a country code. If no language code is specifiedwhen writing, the default language is written and alternate languages forthe tag are deleted. Use the "und" language code to write the defaultlanguage without deleting alternate languages. Note that "eng" is treatedas a default language when reading, but not when writing.
According to the specification, integer-format QuickTime date/time tagsshould be stored as UTC. Unfortunately, digital cameras often store localtime values instead (presumably because they don't know the time zone). Forthis reason, by default ExifTool does not assume a time zone for thesevalues. However, if the API QuickTimeUTC option is set, then ExifTool willassume these values are properly stored as UTC, and will convert them tolocal time when extracting.
When writing string-based date/time tags, the system time zone is added ifthe PrintConv option is enabled and no time zone is specified. This isbecause Apple software may display crazy values if the time zone is missingfor some tags.
By default ExifTool will remove null padding from some QuickTime containersin Canon CR3 files when writing, but theQuickTimePad option may be used to preservethe original size by padding with nulls if necessary.
The tags below are extracted from timed metadata in QuickTime and otherformats of video files when the ExtractEmbedded option is used. Althoughmost of these tags are combined into the single table below, ExifToolcurrently reads 76 different formats of timed GPS metadata from video files.
This directory contains a list of key names which are used to decode tagswritten by the "mdta" handler. Also in this table are a few tags found intimed metadata that are not yet writable by ExifTool. The prefix of"com.apple.quicktime." has been removed from the TagID's below. These tagssupport alternate languages in the same way as theItemList tags. Notethat by default,ItemList andUserData tags arepreferred when writing, so to create a tag when a same-named tag exists ineither of these tables, either the "Keys" location must be specified (eg.-Keys:Author=Phil on the command line), or the PREFERRED level must bechanged via the config file.
This is the preferred location for creating new QuickTime tags. Tags inthis table support alternate languages which are accessed by adding a3-character ISO 639-2 language code and an optional ISO 3166-1 alpha 2country code to the tag name (eg. "ItemList:Title-fra" or"ItemList::Title-fra-FR"). When creating a new Meta box to contain theItemList directory, by default ExifTool adds an 'mdir' (Metadata) Handlerbox because Apple software may ignore ItemList tags otherwise, but the APIQuickTimeHandler option may be set to 0 to avoid this.
The Item reference entries listed in the table below contain information aboutthe associations between items in the file. This information is used byExifTool, but these entries are not extracted as tags.
Tag ID's beginning with the copyright symbol (hex 0xa9) are multi-languagetext. Alternate language tags are accessed by adding a dash followed by a3-character ISO 639-2 language code to the tag name. ExifTool will extractany multi-language user data tags found, even if they aren't in this table.Note when creating new tags,ItemList tags arepreferred over these, so to create the tag when a same-named ItemList tagexists, either "UserData" must be specified (eg. -UserData:Artist=Moneton the command line), or the PREFERRED level must be changed viathe config file.
Tags found in 'infi' atom from some Nextbase videos. As well as these tags,other existing tags are also extracted. These tags are not currentlywritable but they may all be removed by deleting the Nextbase group.
The format of audio and video media files is defined in two parts (three if a file has both audio and video in it, of course): the audio and/or video codecs used and the media container format (or file type) used. In this guide, we'll look at the container formats used most commonly on the web, covering basics about their specifications as well as their benefits, limitations, and ideal use cases.
WebRTC does not use a container at all. Instead, it streams the encoded audio and video tracks directly from one peer to another using MediaStreamTrack objects to represent each track. See Codecs used by WebRTC for information about codecs commonly used for making WebRTC calls, as well as browser compatibility information around codec support in WebRTC.
While there are a vast number of media container formats, the ones listed below are the ones you are most likely to encounter. Some support only audio while others support both audio and video. The MIME types and extensions for each are listed. The most commonly used containers for media on the web are probably MPEG-4 (MP4), Web Media File (WEBM), and MPEG Audio Layer III (MP3). However, you may also encounter MP3, Ogg, WAV, AVI, MOV, and other formats. Not all of these are broadly supported by browsers, however; some combinations of container and codec are sometimes given their own file extensions and MIME types as a matter of convenience, or because of their ubiquity. For example, an Ogg file with only an Opus audio track is sometimes referred to as an Opus file, and might even have the extension .opus. But it's still actually just an Ogg file.
In other cases, a particular codec, stored in a certain container type, is so ubiquitous that the pairing is treated in a unique fashion. A good example of this is the MP3 audio file, which is in fact an MPEG-1 container with a single audio track encoded using MPEG-1 Audio Layer III encoding. These files use the audio/mp3 MIME type and the .mp3 extension, even though their containers are just MPEG.
To learn more about a specific container format, find it in this list and click through to the details, which include information about what the container is typically useful for, what codecs it supports, and which browsers support it, among other specifics.
The 3GP or 3GPP media container is used to encapsulate audio and/or video that is specifically intended for transmission over cellular networks for consumption on mobile devices. The format was designed for use on 3G mobile phones, but can still be used on more modern phones and networks. However, the improved bandwidth availability and increased data caps on most networks has reduced the need for the 3GP format. However, this format is still used for slower networks and for lower-performance phones.
These MIME types are the fundamental types for the 3GP media container; other types may be used depending on the specific codec or codecs in use. In addition, you can add the codecs parameter to the MIME type string to indicate which codecs are used for the audio and/or video tracks, and to optionally provide details about the profile, level, and/or other codec configuration specifics.
Audio Data Transport Stream (ADTS) is a container format specified by MPEG-4 Part 3 for audio data, intended to be used for streamed audio, such as for Internet radio. It is, essentially, an almost bare stream of AAC audio data, comprised of ADTS frames with a minimal header.
The MIME type used for ADTS depends on what kind of audio frames are contained within. If ADTS frames are used, the audio/aac MIME type should be used. If the audio frames are in MPEG-1/MPEG-2 Audio Layer I, II, or III format, the MIME type should be audio/mpeg.
