My video file gets way too big.

HelpPlz wrote on 6/8/2013, 9:30 AM

I had finished my school project (a rap+video in german) when I found out that the video that I had made was very, very big - too big. Also it laggs a lot (audio&video) - not only only on my device but on others too (confirmed on 3 laptops 2 pc). I need to let it play and then replay in order to let it play lagg-free.
Why is it so big and how to prevent it?

Summary

- I used Magix Video Deluxe 16
- This has occured already several times (come to think of it, always!)
- I'm using windows 7 64 bit
- I have a crappy video card but I had no problems during the editing (except for a few preview laggs) - Nvidia GT 230
-  29 Source Files - all around 25sec:  777 MB
 As you  can see only used snippets of it to fit it in a 3 minute video
-

-Output video: 5.82 Gb 3:00 min

Past video's:
2 min vid. 3.94 GB 720-1280
80 min 353 GB 1080-1920 (I know this is very high for such a long video, but 353gb!)
-- I stopped making any videos with this software until now because of the lagg.



Ps: Forgive me my English, I'm dutch and tend to mix up all the tenses.
Pps: I couldn't find the right product category

Hi,

File Size = bitrate x run time  video resolution really has little to do with file size.  What format are you using to export your video.  If you are using the AVI package, your file size is likely to be huge because this package by default uses very high bit rates which will also cause lag because most computer systems cannot handle bit rates that are as high as what a long AVI video generate.

Here is an example of how bit rate affects file size.  You can see by the file length that this is the same video just saved in different formats not the huge difference in the AVI file's total bit rate and the resulting difference in file size.

HelpPlz,

You've provided a lot of information but not the one bit that's probably most important! What is the format of your final export? If you output is ordinary mpeg (standard for DVDs) you should be able to get over an hour onto a 4.7GB disc.

Regards,

Carl,

Ty for all your awnsers and I hope a moderator can close this question (and maybe delete this acc).
I exported it indeed in .avi (most common, safe bet.
So you're both right, thanks!
