how to make .avi high definition movie file smaller

[jarko]

Hi,

I have few big movies files about 6-10GB and I want to convert them with same video quality to smaller one.
I see sometimes some movies with amazing quality in size like 300-500MB.
Can someone help and tell me what is the best application to do this or some info how to do this process.
Thx in advance for any help!!!!

PLease give more information about your source. Yes, you can make 6gb uncompressed video to 300mb with almost same quality. But not any 1080p full movies to 300MB.

And try shrink with vidcoder, megui, etc and see how it looks like.

Hi,

More information about file:

Duration:01:45:32
Resolution:1920 x 1080
Bit Rate:9264 kbps
Frame Rate:24
Sample Rate:48000 kbps
Bit Rate:1509 kbps
Channel:6 Channel
This file is mkv and is 8.3GB size

P.S.
This high resolution doesn't have to be so high. I just want really good quality of this video when I'll be watching on big LED screen.

Try vidcoder. Resize to 1280x720 with h264 video and use high quality x264 preset(SLOW). Set the output file size to around 500MB. Shrink the audio to aac with a low bitrate. Test and see how it looks like.



Or buy a bigger a HDD.

Ok, I'm gonna try.

I use format factory more than any of my 14 Different Encoders

for 1080p to 720p efficient conversion...

Go to Task -> Option -> H264

fourcc: h264
Level IDC: 51
VBV Maxrate: 16600
Motion Estimation Algorithm: esa Exhaustive Search
Sets Maximum Interval Between Key Frames: 250
Number of previous frames used as predictors in B- and P-frames: 5
Maximum number of consecutive B-frames between I- and P-frames: 5
Use Cabac: check the box
Use Multithreads: check the box


Choose All to MKV -> output setting -> profile: high quality and size

Type: MKV
Use system decoder (AviSynth): Off

Video Stream
Video Encode: AVC(H264)
Video Size: 1280x720
Bitrate: (choose this yourself)
FPS: Default
Aspect Ratio: Fully Expand
Encode 2 Pass: Yes

Audio Stream
Audio Encode: AAC
Sample Rate: 48000
Bitrate: 128
Audio Channel: 2
Disable Audio: No
Volume Control: 0 dB
Audio Stream Index: Default

Not going to happen!!
To make it smaller you need to throw out information which means you will not have the same quality.

I see sometimes some movies with amazing quality in size like 300-500MB.

On what ??
An Ipod ?
A 13" crt tv ??



You surely are NOT going to take a video that is 1280x720 & 6gb-10gb & compress it down to 300-500MB & have it anywhere near the original quality, unless of course you are watching it on a Ipod or 13" crt, or you are half blind.......

This high resolution doesn't have to be so high. I just want really good quality of this video when I'll be watching on big LED screen.

Oy Vey.....

100%.

A 500Mb file is unwatchable to me on my 23" monitor. As mentioned, how can you expect to lose 90% of the information and somehow retain quality? Anyone who thinks a 350Mb feature length video is high quality either is watching it on their phone or needs their eyes examined.

If you want to play with shrinking the video, fine, but you'll need advanced h.264 options to get decent results. Be prepared to do some research. And it'll take a long time to encode.

Is saving up for more external drives sounding good at this point?
