How Do All You People Learn All This Stuff About Editing???

[classfour]

Floppy..........AND..Modem?

Why?

Because you like dial up?

I have a stack of 1.44's at the office that you can take a crack at - just burn the files to CD (one should suffice)

What would you do if you came across a 5.25 inch floppy?

Please don't ask what a 5.25 inch floppy is - it may offend me.

READ the tutorials, then ASK these folks here when you are stuck.

As long as you're not a gravedigger (unearth old threads and resurrect to #1 on the "list") or a Troll - they're great folks from the world-wide community that are helpful.

READ the tutorials.

and -

READ the tutorials.

Don't get hung up on some of the graphic input and overwhelming knowledge that ED has: He's waaaaaaaaaay into it.

AND,

MOST Important:

Never

Ever

Do anything to harm, irritate or step on Baldrick.

It's his site, he hosts. The rest of us will defend the heck outa him (not that he needs it, he can boot you off in a minute).

Ask on.

AAAAAAAAAAAAAAAAAAAAAAAAA - classfour please help, i think that i've made something wrong few e-days ago..., i've not agreed with Baldrick - is there any hope for me? i'm just poor guy from Europe... is there any rescue? any chance? AAAAAAAAAAAAAAAAAAAAAAAA classfour HELP - i'm so desperate... please!
Seems that Baldrick is smart guy but anyway - is there any hope for me?

I know you directed that at someone else however People still have floppies. I sell a few USB floppy drives every month.

56K modem. That could be someone wants to Fax from their computer or no High Speed Internet or because it is still cheapest way to the internet. I get customers with the first and last reason here all the time.

How about 8" floppies. They along with 5.25" were still in use when I got into computers.

TBoneit - Don't those 5.25 inch drives have weird connectors that nobody supports any more? You can still find 3.5 inch floppy drive connectors on modern motherboards or just buy a USB one, but if I remember correctly those 5.25 inch drives used a completely different kind of connector.

Floppy drive cables, both for 3.5" 1.44 MB and 5.25" 1.2 MB, have the same motherboard connector end. For 286s it was standard to have both size floppies, on one cable with two plugs for either or both kinds of drive as A: and B: (which is why the first hard disk is C.

So 5.25s should physically work with any motherboard with a floppy socket. It's possible they removed support in the BIOS, but it costs them nothing to leave it in.

Yes the 5.25" had a edge connector instead of pins as well as a different power connector.

Support for 5.25" floppies is missing in the BIOS in my computers. I guess they decided they needed the room?

I still have some stuff on 5.25" floppies I'd like to get off. I have the drive but ran out of the cable with the connector to use them. Plus I will have to use a older computer with support for 1.2Meg floppies.

As will most things in life you Learn by Doing, reading is good but for most doing and re-doing thru trial and error is the best teacher, then use the tools available like Bing or Google as well as forums like this one...

Hopefully this is more use than adding to the confusion (and funny off topic'ness of this thread)...

Anyhow. I posted this a while back and gave some background as to what containers are and the video or audio or subtitles that they contain.
https://forum.videohelp.com/threads/308650-HOWTO-Edit-Motion-JPEG-(MJPG)-in-Adobe-or-ev...=1#post1900958

Here's my everything video/audio 101 community college pitch I just thought up...

CONTAINER - this is the filename.avi, filename.mov etc that you see after capturing off of camera or downloading a film from an email your friend sent you.
eg
QuickTime MOV
Microsoft AVI
Various sorts from the Motion Picture Experts Group (MPEG) (mpg, mts, m2ts, mp4)

These containers all hold streams of information - think of each stream like a piece string wrapped up with other pieces of string to make a "rope" of information. Typically this information is Video or Audio or Subtitles.

VIDEO - eg

Advanced Video Codec "AVC" aka "H.264" aka "MPEG4-part10" - this is used on YouTube, Blu-ray, Digital Cable TV, Satellite TV, etc etc... This is because it's high quality image with high compression thus you need less bits per second vs older technologies

MPEG2 - as used on DVDs and older satellite transmissions.

Visually Lossless (see below*) - also called a "Digital Intermediate". Examples are free ones like "HuffyYUV" and "UT_Lossless" or commercial ones like "CineForm" or "Apple ProRes"

AUDIO - eg

raw uncompressed digitized audio. For example, 8 bit stereo is a value between 0 and 255 for VolumeLeft,VolumeRight, then the next Vol' Left, next Vol Right, etc etc - it is called "PCM"

Compressed audio like Dolby Digital "AC3" - capable of 1 (mono), 2 (stereo), 6 (5.1surround) encoding schemes. This is a "Lossy" encoding scheme (see below*).

MPEG1 part3 "mp3" - this is a lossy scheme

Subtitling text

Depending on what the goal is this container you choose differs - for example, over a satellite link is different to what you would want to use for Video Editing.

*Lossy compression technology throws away the parts of the video or sound that you can't perceive and thus is a lossy (ie the output is not the same as the input) compression technology. - the implementation is just smart about which bits they throw away (this is true for all lossy video and audio compression/decompression schemes "codec = COmpression/DECompression). Do not confuse Visually or Audibly LOSSLESS with UNCOMPRESSED. Uncompressed is just that - it's the raw numbers describing each pixel of video (in Red,Green,Blue (RGB) or Component (YUV) one after another. For audio it's the sound pressure at that moment in time. PCM Audio is uncompressed. Video is rarely stored uncompressed because it is a HUGE amount of information.

Choice of container has it's pros and cons. The same is true for each sort of Video or Audio compression. You may choose it because a standard like DVD or Blu-ray require it. Or you may choose it for it's ease of decode (ie a slow PC can do it). Back in the 80's Motion JPEG (which is basically JPG photos one after another) was very popular because a Intel 486 100MHz could do 30 frames a second of it. Likewise these days, probably one of the most computationally intensive compression schemes - AVC is popular for long term storage because it is small but still very high quality or even visually lossless. AVC uses a lot of "temperal" information though (information from prior and after frames) so is not good for Editing because of the jumping around nature of the process. Instead a hybrid/chopped down version is becoming popular - "AVC Intra" which is like Motion JPEG in that it has no temperal qualities - ie it just compresses the one frame of video at that instant. It is thus easy to get and change one frame without effecting prior or post frames.
When you drag a, for example, video stream out into it's own file with no Container wrapping it up it's called an Elementery Stream. Some examples of those are .264 for the AVC video compression technology. m2v for the MPEG2 video compression technology, ac3 for Dolby Digital's (proprietary) Audio compression technology.

It only gets tricky when someone uses the wrong file extension - it's tricky because most players will ignore the file extension and look at the information in the file to work out what it really is. This leads to confusion (and delay - a Thomas The Tank Engine reference I have to make it; I have a 2yr old).
There are MANY tools out there that can manipulate the outside CONTAINER as well as add or remove a stream - or replace with another type by "re-encoding".
When you are editing video and audio you are de-containering (called de-multiplexing) it into its Elemental Streams, manipulating them and then pushing them back out as Elemental Streams (ES) or bundle it (called multiplexing) into the appropriate container for delivery and/or permanent storage.

Hopefully this semi-visual presentation helps.
