Video file size issue

[maviczap]

I'm editing a video, and I've added a video file in Mp4 format

In Windows, it shows the file size as 1.12gb, but when I add it into the video editing software, its using 4gb?

So its taking up all the space on a blank DVD, which be the final output. Its only 1hr 15minutes of footage, so should only take up the 1.12GB

I've tried converting to another format to reduce its size, but the its still using up 4gb after I've converted the file.

I'm puzzled

What program? You can usually choose what compression you use for video and audio which will affect the file size

i think i'm right on this but its been a loooooong time since i have done any video editing so...

if you are converting to dvd then the disc needs to finalise so will take all space to do so, if you dont finalise then it might not be readable in drives. the data will not be or it might be larger depending on how compressed the mp4 was. remember that mp4, iso and mkv are all 'containers' just like rar and zip. with exception of iso the other formats can be compressed so when you decompress them e.g. burning to dvd the file size is actually bigger. usually not the size your looking at though.

the editing software will also need ram to decompress and will show as a bigger file. your going from a compressed file to a 'raw' file. 4gig for 1hr 15min sounds about right for dvd. most of your newer dvd's are 'DL' and as such can store longer movies.

I miss the included dvd program in 7.
What's the best for ten.
Win X got me out of a corner.
But then it's free and you obviously get better.

So far

Win X HD converter

Freemaker Video converter

Both have converted stuff in the past and reduced the file size, but not this time?

I used Handbrake to burn the file to a DVD RW which reduced it to about 3gb, from the +4gb.

Even though the file size is shown as 1.12gb in windows, there's another 3gb that I can't see.

Currently in my DVD menu I've got about 3gb from 2 titles, which are about an hour each.

When I add this file to the list, even though its only 1.12, the capacity bar for the dvd jumps to nearly 7gb for the dual layer dvd?

You can tell its better quality footage, but why is it only showing 1.12gb?

I'm just trying VLC media player to convert it

if you are converting to dvd then the disc needs to finalise so will take all space to do so, if you dont finalise then it might not be readable in drives. the data will not be or it might be larger depending on how compressed the mp4 was. remember that mp4, iso and mkv are all 'containers' just like rar and zip. with exception of iso the other formats can be compressed so when you decompress them e.g. burning to dvd the file size is actually bigger. usually not the size your looking at though.

You're on the money I think, as I read something along these lines, I think the 3gb is in part of the container I can't see.

Not got to the finalising part yet, just adding the files to the menu.

is it the mp4 that is 1.2gig or the 'raw edited' file that is 1.2gig?

also dont use 'RW' discs you dont need to, in fact some older DVD standalone players dont recognise them. just use standard discs.

if the disc is not going to be played in an older standalone player then no need to convert to 'DVD structure'. most new dvd players of say 5 years should happily play mp4.

how many of these discs are you needing to make?

have you added a 'menu' to the mp4 file and is it working on the PC or have you edited in Raw, 'dvd structure' with menu?

i'm not fully up on creating dvd's these days as i'm working the opposite way. someone with more knowledge than me might be along to help :-)

[maviczap]

Well the VLC conversion didn't work very well.

However I did manage to convert the mp4 to to a DVD, which can be opened, and this then shows the Mp4 contained 3 chapters, all 1.4gb in size, so that explains why the file shows within my DVD editor as being at least 3gb.

So the MP4 file must contain the same, but the shell of the MP4 container only registers 1.12GB

Bib's I'm only using DVD RW to convert the file into a DVD, my blu ray player plays it no problem, the final disc will be DVD DL

[Bibio]

when you are using your editing software to create the OSD for chapters and such are you working directly with the mp4?

most editing software these days can split your mp4 into sections or add 'metadata' index to tell the OSD where the 'chapters' are. ''''you can then save the whole project as'''' mp4 or mkv, etc.etc. once you have 'compiled' your mp4 or mkv with index and OSD then you just need to burn as 'data disc'. if your bluray/dvd player supports mp4/mkv playback then it will read the file from the disc. as long as everything is contained within the mp4 or mkv.

if your just doing this for yourself then no need to burn a disc and instead just put the 'compiled' mp4/mkv it on a thumb drive and plug into tv or bluray player usb port.

if you want to hand hard copies out to friends and family not knowing what hardware they have the yes you need to burn as 'dvd' if not then burn the compiled mp4 or mkv as 'data disc'.

as long as the finished product contains all the chapters and OSD it matters not what the 'container' (mp4 or mkv) is as long as that container supports playback of chapters etc.etc

its the converting to 'DVD' that is taking up the space as its decompiling the mp4 to 'raw'.

its the same as burning a CD using mp3's even though the mp3 is 1.2mb when its converted into 'WMA' it will be 10 times the size depending on the original mp3 bit size.

Back in the day when I used optical discs any time I created a DVD I just used the main title and binned all the menus and rubbish.
I used Devede to create the ISO then Brasero to write it.
There's a Devede for Windows but don't know if its any good.
The Linux version works a treat ;)

That's similar to how I do it, but all within Nero, create the ISO first and then burn it, less drinks coasters this way.

Well didn't really resolve anything, I did find a program that stripped out one audio track, that I didn't need and then converted the file into MKV format at the same time. But Nero 9 doesn't allow use of MKV in DVD, its a blu ray format. Converting this MKV into a MPEG format changed the file size back to 5.2gb!

However to cut a long story short, I was able to rerecord the file again, and insert it into the DVD, another day gone!

Thanks for the suggestions.

i'm getting a bit confused here so a few questions.

are you editing the mp4 so it has chapter and navigation using editing software?
if you are doing as above what format are you saving your 'project' as e.g. mp4, mkv, xvid etc.etc?

most modern dvd/bluray/tv's have a usb port that you can play files from and they usually support mp4, mkv etc.etc.
does your dvd/bluray/tv have a usb port?

btw never ever use your original file to edit always use a copy that way if you mess up you still have the original to copy again.

Question 1. No I'm inserting the Mp4 into a DVD, the DVD has the menu and seperate titles, but because the Mp4 file is too big it makes the overall DVD size over the limit and I still had two more files to add. I was trying to convert it to a smaller size, but as soon as you convert any Mp4, it unwraps it from its container and trebles the file size.

Question 2. Saving file to ISO using Mpeg format for DVD, so limits size to 8.5gb dual layer discs

Question 3. Sending DVD to friends in far far away land, I wish they'd upgrade to a blu ray play, so I could send them a blu ray or USB

Yes, always working with a copy

[Bibio]

think i know what you are doing now. you have a 'dvd template' then extracting the mp4 and adding the files to the template.

if you have a 'dvd structure' then you can use something like 'dvd shrink' to shrink the dvd structure to a smaller size then burn the dvd. or if you already have the final on a dvd you can still use dvd shrink to make a new compressed copy then burn that. check the quality of the new files before burning to a new disc.

or when converting the mp4 you can usually adjust the output size. but you need conversion software.

dvd shrink, that takes me back, its so long ago I had forgotten about that one.
