Alright, i'm down to crunch time. I have a video that I have rendered out for something I have to turn in. The submission requires that it be At Most: 200 MB and be one of the following formats:
- .avi
- .dv
- .mov
- .qt
- .mp4
- .mpeg
- .3pg
- .asf
- .wmv
- .mpg
It's my goal (as is many peoples goal) to preserve as much quality as possible. The problem is, my video is currently 721.99707 MB! Out of the formats, which are the best for me to try? What other methods can I apply to shrink the file size while still trying to keep as much as possible of the original quality.
I'm sure I'll have to use something lossy (as much as I would prefer not). I'm just looking for a best solution, not a God solution if you know what I mean.
Thanks so much!
EDIT
Sorry, a commenter pointed out some good questions.
- Current Format: .mov
- Current Bit Rate: 1135kbps
- Current Framerate: 30fps
- Current Resolution: 720 x 480
- Length: 3 Minutes, 22 Seconds
I would prefer that the resolution not go down any more. It will be viewed in a box about the size of its current resolution, however, if it is necessary, then I will shrink it...
What format and codec is the 722MB file? Is it currently in a lossless format or has it already been lossily compressed? What's the resolution, framerate, A/V bitrate? What are the output requirements? Can you reduce the resolution or does it have to be in its current resolution? – Lèse majesté – 2012-04-13T07:13:48.677
@Lèsemajesté Touche - I've edited my post with the new details. – Freesnöw – 2012-04-13T07:19:51.327
How long is that video? – Daniel Beck – 2012-04-13T07:39:01.177
@DanielBeck 3 Minutes, 22 Seconds. – Freesnöw – 2012-04-13T07:40:51.907
That's 3.5MB per second. Are you really sure about those numbers? Also, this might be relevant reading (slhck isn't just incredibly helpful, but also studies this stuff — you might find him in the Root Access chat room).
– Daniel Beck – 2012-04-13T08:15:54.290@DanielBeck Yes, they are correct. – Freesnöw – 2012-04-13T08:17:25.500
I assume by .avi, it means some sort of divx codec. Try that. – Pygar – 2012-04-13T07:15:08.727
I'll come back to you later once I have access to my computer, but basically the answers below are correct. It's a matter of using the correct encoding settings. What's your OS? – slhck – 2012-04-13T09:51:47.077
1Yep, AVC is a good video codec, though you should have no problem compressing your video into the desired range using almost any modern codec without sacrificing much quality. I've seen 1280x688 video files compressed down to an overall bitrate of 626 Kbps, which is only 0.0764 MB/s. That was using AVC & AAC. If you achieved the same compression ratio, your video would only be about 5.84 MB. Tack on a 96 Kbps audio stream, and you'd just barely top 8.2MB. – Lèse majesté – 2012-04-13T10:18:39.033
