Large upload permission

Uanime5 · Post by **Uanime5** » Tue Jan 17, 2006 6:33 am

I created an AMV that was over 158mb large and applied for permission to upload it. Once this was granted people kept complaing that it was too large and adviced me to reduce it by compressing the audio. I then reduced the file size down to 122mb, however I had a problem when I tried to reupload it (after being uploaded the file size read ??? and it would delete itself). As this file is still over 100mb I realised that I needed to reapply for permission to upload it.

While I'm not saying that once you have recieved permission to upload an AMV over 100mb you should be able to change it to an AMV of any size you want it would be helpful if you could reduce the size and reupload it without having to reapply for large upload permission.

Compress your video.

And your audio too. Don't be afraid to knock the quality down slightly.

The guide says that you should not go above 20mb for per minute. This AMV is over 5 minutes long. Therefore 122mb is not an unreasonable size. Also since the orginal song was over 8 minutes long I could have made an AMV that was 160mb.

Also the second pass does not work every well in my experience (it can take off a few mb but it cannot go below a certain point no matter how low you set it). So saying compress it is not very helpful.

I find it very strange that a-m-v.org would so quickly allow me to upload a 158mb (I got permission in a few days) but it seems to be dragging its heels over my reduced file (over a week and still no response). This attitude will discourage AMV makers from compressing their AMVs.

At the end of the encode, you should load the avi into your favourite media player and see how it looks. If you've followed the guides diligently then everything should look great.

Other playback problems may occur if you don't have an up-to-date DivX decoder installed or your decoding settings are in some way messed up. This is usually not a problem with the encode.

OK, if you are sure it looks good then we can continue. What was the final size of the video? If the size is small enough for you to go ahead and distribute (40mb is the average size for a 3 or 4 min simple amv) then your encode is complete!

However, if your first pass encode is on the big side (between 70 and 120mb) then you will need to do a second pass to reach a desired filesize. If your first pass is bigger than 120mb you should consider reducing the frame size of your video or doing heavier filtering. The question is, what should that filesize be?

Of course it is up to you, but if you want something to still look pretty decent then you should aim to have your final encode be around 70% of the first pass size. This is not always possible as some videos are hard to encode but don't be a quality whore about it; really you should never go above 20mb for each minute of video as that's getting excessive. You can also go much much smaller than 70% first pass if you like, but if you start getting major blocking then reducing the resolution and doing better filtering may well be a better option than just reducing the target size. Encoding well requires a lot of trail and error.

If you compress your audio, reduce the resolution to 512x384 (assuming initial is 640x480), and set a target filesize of 60 MB for the second pass, I would be very surprised if a) the resulting file was much above that or b) ended up looking like junk, assuming that you used a proper resize filter. Encoding to reasonable filesizes is most of the time not nearly as hard as the guide makes it out to be.

Are these permisions to upload 100MB+ amv's given freely or is the org using holographic storage now?

What does holographic storage mean?

Basically if you want to upload a large AMV you go through the upload process, then on the upload information screen you select large upload and fill in your details (size, how you've tried to reduce it). a-m-v.org then reviews your AMV and decides if it is an acceptable size. At the moment they seem to be taking a very long time to review them.

Holographic storage is a mode of storing information like a hologram. The result is huge storage capacity (think a harddrive the size of a CD with about 10TB of space) that's a bit prohibitivly expensive at the moment.

What the others are saying is that you video shouldn't have been allowed to be upoaded in the first place (in thier opinion) and that the person who allowed it made a mistake.

Not to be a picky body, but it's more like 200 GB on a CD sized media. But still the same principle.

I really don't know about all of the new advances, but IBM was touting Wristwatch-sized 1TB drive about 5 years ago.

The actual disk in a hard disk is the same size as a normal 12cm CD. Though there can be two or 3 disks inside one hard disk. Mechanical storage is starting to reach its limits in how densly bits can be packs into a specific area. Holohraphic storage is simply the next evolutionary step. I havent heard anything about their read/write speeds, anyone got some idea?
