When this is complete, you’ll see the Encode Finished message appear in the app. You’ll find your compressed video in the destination you selected earlier. Movavi is another useful video editor that you can use for free to compress a video on Mac. Compress files using tar, gzip, bzip2, zip, p7zip formats. Show details Hide details. Compress/archive/email files and omit Mac-specific invisible files. Gzip Mac Command gzip command is a file format which is used to compress or decompress the files or folders. The compression methods currently supported are deflate, compress, lzh (SCO compress -H) and pack. The crc is given as ffffffff for a file not in gzip format. With -name, the uncompressed name, date and time are those stored within the compress file if present. When compressing, gzip uses the.tgz extension if necessary instead of truncating a file with a.tar extension. Gunzip can currently decompress files created by gzip, zip, compress, compress -H or pack. The detection of the input format is automatic. When using the first two formats, gunzip checks a 32 bit CRC.
File compression is the process of taking several (or many) files and combining them into one, smaller file. This smaller file can then be uncompressed and returned to their separate, regular sized files.
There are various reasons to compress files, but the foremost is that you want to make the file more manageable. By compressing, you make the file size smaller, and, if there are multiple files, they are grouped together. This grouped together file is called an archive file.
If, for example, you wanted to send a few pictures via email to a friend, you might find that the pictures take a long time to send because their file size is so large.
So the natural thing to do would be to make the file size smaller. You can do that by compressing the images.
Likewise, if you wanted to quickly download the contents of a directory on your hosting account (for example, your entire public_html Breeze 1 6 oz. directory), you could create a compressed version of that, then download the entire archive file in one go. That way you don't need to copy multiple files or worry about the transfer size.
There are different kinds of compression, so it's important to make sure that you use the best compression method for your situation. Here are some popular ones:
.ZIP is one of the most popular compression methods, known for its quick compression and extraction times. It's suitable for both Windows and Mac users.
TAR.GZ is great for Unix users and by extension, Mac users. Many MacOS versions allow you to double-click a TAR.GZ file to extract it. However, if you are a Window's user, you will need additional software to extract a TAR.GZ file.

For applications that require data compression, the functions in this moduleallow compression and decompression, using the zlib library. The zlib libraryhas its own home page at https://www.zlib.net. There are knownincompatibilities between the Python module and versions of the zlib libraryearlier than 1.1.3; 1.1.3 has a security vulnerability, so we recommend using1.1.4 or later.
zlib’s functions have many options and often need to be used in a particularorder. This documentation doesn’t attempt to cover all of the permutations;consult the zlib manual at http://www.zlib.net/manual.html for authoritativeinformation.
For reading and writing .gz files see the gzip module.
The available exception and functions in this module are:
Exception raised on compression and decompression errors.
Computes an Adler-32 checksum of data. (An Adler-32 checksum is almost asreliable as a CRC32 but can be computed much more quickly.) The resultis an unsigned 32-bit integer. If value is present, it is used asthe starting value of the checksum; otherwise, a default value of 1is used. Passing in value allows computing a running checksum over theconcatenation of several inputs. The algorithm is not cryptographicallystrong, and should not be used for authentication or digital signatures. Sincethe algorithm is designed for use as a checksum algorithm, it is not suitablefor use as a general hash algorithm.
Changed in version 3.0: Always returns an unsigned value.To generate the same numeric value across all Python versions andplatforms, use adler32(data)&0xffffffff.
Mac http downloader. Compresses the bytes in data, returning a bytes object containing compressed data.level is an integer from 0 to 9 or -1 controlling the level of compression;1 (Z_BEST_SPEED) is fastest and produces the least compression, 9 (Z_BEST_COMPRESSION)is slowest and produces the most. 0 (Z_NO_COMPRESSION) is no compression.The default value is -1 (Z_DEFAULT_COMPRESSION). Z_DEFAULT_COMPRESSION represents a defaultcompromise between speed and compression (currently equivalent to level 6).Raises the error exception if any error occurs.
Changed in version 3.6: level can now be used as a keyword parameter.
Returns a compression object, to be used for compressing data streams that won’tfit into memory at once.
level is the compression level – an integer from 0 to 9 or -1.A value of 1 (Z_BEST_SPEED) is fastest and produces the least compression,while a value of 9 (Z_BEST_COMPRESSION) is slowest and produces the most.0 (Z_NO_COMPRESSION) is no compression. The default value is -1 (Z_DEFAULT_COMPRESSION).Z_DEFAULT_COMPRESSION represents a default compromise between speed and compression(currently equivalent to level 6).
method is the compression algorithm. Currently, the only supported value isDEFLATED.
The wbits argument controls the size of the history buffer (or the“window size”) used when compressing data, and whether a header andtrailer is included in the output. Enolsoft pdf converter with ocr 6 8 0 8. It can take several ranges of values,defaulting to 15 (MAX_WBITS):
+9 to +15: The base-two logarithm of the window size, whichtherefore ranges between 512 and 32768. Larger values producebetter compression at the expense of greater memory usage. Theresulting output will include a zlib-specific header and trailer.
−9 to −15: Uses the absolute value of wbits as thewindow size logarithm, while producing a raw output stream with noheader or trailing checksum.
+25 to +31 = 16 + (9 to 15): Uses the low 4 bits of the value as thewindow size logarithm, while including a basic gzip headerand trailing checksum in the output.
The memLevel argument controls the amount of memory used for theinternal compression state. Valid values range from 1 to 9.Higher values use more memory, but are faster and produce smaller output.
strategy is used to tune the compression algorithm. Possible values areZ_DEFAULT_STRATEGY, Z_FILTERED, Z_HUFFMAN_ONLY,Z_RLE (zlib 1.2.0.1) and Z_FIXED (zlib 1.2.2.2).
zdict is a predefined compression dictionary. This is a sequence of bytes(such as a bytes object) containing subsequences that are expectedto occur frequently in the data that is to be compressed. Those subsequencesthat are expected to be most common should come at the end of the dictionary.
Changed in version 3.3: Added the zdict parameter and keyword argument support.
Computes a CRC (Cyclic Redundancy Check) checksum of data. Theresult is an unsigned 32-bit integer. If value is present, it is usedas the starting value of the checksum; otherwise, a default value of 0is used. Passing in value allows computing a running checksum over theconcatenation of several inputs. The algorithm is not cryptographicallystrong, and should not be used for authentication or digital signatures. Sincethe algorithm is designed for use as a checksum algorithm, it is not suitablefor use as a general hash algorithm.
Changed in version 3.0: Always returns an unsigned value.To generate the same numeric value across all Python versions andplatforms, use crc32(data)&0xffffffff.
Decompresses the bytes in data, returning a bytes object containing theuncompressed data. The wbits parameter depends onthe format of data, and is discussed further below.If bufsize is given, it is used as the initial size of the outputbuffer. Os x server 5 1 download free. Raises the error exception if any error occurs.
The wbits parameter controls the size of the history buffer(or “window size”), and what header and trailer format is expected.It is similar to the parameter for compressobj(), but acceptsmore ranges of values:
+8 to +15: The base-two logarithm of the window size. The inputmust include a zlib header and trailer.
0: Automatically determine the window size from the zlib header.Only supported since zlib 1.2.3.5.
−8 to −15: Uses the absolute value of wbits as the window sizelogarithm. The input must be a raw stream with no header or trailer.
+24 to +31 = 16 + (8 to 15): Uses the low 4 bits of the value asthe window size logarithm. The input must include a gzip header andtrailer.
+40 to +47 = 32 + (8 to 15): Uses the low 4 bits of the value asthe window size logarithm, and automatically accepts eitherthe zlib or gzip format.
When decompressing a stream, the window size must not be smallerthan the size originally used to compress the stream; using a too-smallvalue may result in an error exception. The default wbits valuecorresponds to the largest window size and requires a zlib header andtrailer to be included.
bufsize is the initial size of the buffer used to hold decompressed data. Ifmore space is required, the buffer size will be increased as needed, so youdon’t have to get this value exactly right; tuning it will only save a few callsto malloc().
Changed in version 3.6: wbits and bufsize can be used as keyword arguments.
Returns a decompression object, to be used for decompressing data streams thatwon’t fit into memory at once.
The wbits parameter controls the size of the history buffer (or the“window size”), and what header and trailer format is expected. It hasthe same meaning as described for decompress().
The zdict parameter specifies a predefined compression dictionary. Ifprovided, this must be the same dictionary as was used by the compressor thatproduced the data that is to be decompressed.
Note
If zdict is a mutable object (such as a bytearray), you must notmodify its contents between the call to decompressobj() and the firstcall to the decompressor’s decompress() method.
Changed in version 3.3: Added the zdict parameter.
Compression objects support the following methods:
Compress data, returning a bytes object containing compressed data for at leastpart of the data in data. This data should be concatenated to the outputproduced by any preceding calls to the compress() method. Some input maybe kept in internal buffers for later processing.
All pending input is processed, and a bytes object containing the remaining compressedoutput is returned. mode can be selected from the constantsZ_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH,Z_FULL_FLUSH, Z_BLOCK (zlib 1.2.3.4), or Z_FINISH,defaulting to Z_FINISH. Except Z_FINISH, all constantsallow compressing further bytestrings of data, while Z_FINISH finishes thecompressed stream and prevents compressing any more data. After calling flush()with mode set to Z_FINISH, the compress() method cannot be called again;the only realistic action is to delete the object.
Returns a copy of the compression object. This can be used to efficientlycompress a set of data that share a common initial prefix.
Changed in version 3.8: Added copy.copy() and copy.deepcopy() support to compressionobjects.
Decompression objects support the following methods and attributes:
A bytes object which contains any bytes past the end of the compressed data. That is,this remains b' until the last byte that contains compression data isavailable. If the whole bytestring turned out to contain compressed data, this isb', an empty bytes object.
A bytes object that contains any data that was not consumed by the lastdecompress() call because it exceeded the limit for the uncompressed databuffer. This data has not yet been seen by the zlib machinery, so you must feedit (possibly with further data concatenated to it) back to a subsequentdecompress() method call in order to get correct output.
A boolean indicating whether the end of the compressed data stream has beenreached.
This makes it possible to distinguish between a properly-formed compressedstream, and an incomplete or truncated one.
Decompress data, returning a bytes object containing the uncompressed datacorresponding to at least part of the data in string. This data should beconcatenated to the output produced by any preceding calls to thedecompress() method. Some of the input data may be preserved in internalbuffers for later processing.
If the optional parameter max_length is non-zero then the return value will beno longer than max_length. This may mean that not all of the compressed inputcan be processed; and unconsumed data will be stored in the attributeunconsumed_tail. This bytestring must be passed to a subsequent call todecompress() if decompression is to continue. If max_length is zerothen the whole input is decompressed, and unconsumed_tail is empty.
Changed in version 3.6: max_length can be used as a keyword argument.
All pending input is processed, and a bytes object containing the remaininguncompressed output is returned. After calling flush(), thedecompress() method cannot be called again; the only realistic action isto delete the object.
The optional parameter length sets the initial size of the output buffer.
Returns a copy of the decompression object. This can be used to save the stateof the decompressor midway through the data stream in order to speed up randomseeks into the stream at a future point.
Changed in version 3.8: Added copy.copy() and copy.deepcopy() support to decompressionobjects.
Information about the version of the zlib library in use is available throughthe following constants:
The version string of the zlib library that was used for building the module.This may be different from the zlib library actually used at runtime, whichis available as ZLIB_RUNTIME_VERSION.
The version string of the zlib library actually loaded by the interpreter.
