As original Ranking Criteria:

Ranking Criteria wrote:

The video's dimensions must not exceed 800x600 for the 4:3 format, or 854x480 for the 16:9 widescreen format. This is so video files keep a decent filesize and do not increase the beatmap's size by too much.
Seriously. The video dimensions isn't main reason to increase the file size, but the bit rate.
encode bit rate:1800 vs 600
1800 bit rate:

600 bit rate:

file size: 18.9MB vs 7.18MB

I used same format to encode the video (overall bit rate: 1800, FPS:20.000):
854x480's information
1280x720's information
Only increase the video size 0.3MB. How about video definition?
Compare definition(please click it to check original size)
854x480:

1280x720:

854x480:

1280x720:
Let's discuss video dimensions again and thanks for your read ;)

The higher system specs required to decode higher complexity videos is something to consider.

What kind of system specs as a minimum should you have to be able to decode 720P? It's 2014 already. Toasters for 720P should (almost) be a thing of the past!

Support, if we put rules in place for either bitrate or file size instead.

Hi, I have an Ivy Bridge i3 that can barely render the current 480p BG videos without causing the game to lag.

As a (TV size) mapper i would be glad to see this rules changed, I always enjoy play maps with videos.

and well as Dkun said

The option to not play video is available: the lower-end machines can still play the game - just not with all the bells and whistles. Look at guy who posted earlier saying he can't even play videos that meet the current criteria. He won't be using video regardless of what is decided here. I don't mind seeing a higher cap on what we are able to post if it doesn't have a noticable effect on the file size itself.

Yes, spboxer3 knows exactly.
But as mm201 said, higher dimensions requires more system resource.

Look at the fps and the quality of these pictures please.

Play with 1920x1080 video

Play with 704x396 video

Both video files have same bitrate 1000, but the size is not big different.


The point is this.
1. To play HD video requires higher system specs.
2. HD video requires high bitrate to keep the quality. If you give low bitrate for HD video, it's not HD anymore.

But the current ranking criteria doesn't explain correctly the reasons why we limit the video's dimensions.

By the way I'm really weak at making proper sentense because of my bad English skill.
So please someone fix the ranking criteria if you understand the point that I wrote.


And.. I agree with increasing the dimensions of the video to 1280x720 for 16:9. Yeah, it's 2014 already.

There hasn't been much activity here lately, but felt like casting my support behind the change.

As already stated on the thread, with the file size limit already in place, there really is little point to limiting to 480p when me sad 5 yr old laptop with an AMD Tuturion x2 with ATI Mobility HD 3450 (in short inferior to the Intel HD4000) can run a 720p video. So unless you fall into the category

On a slightly unrelated note, I did notice, that when I sent osu! videos with really high bitrates (200mb in 4min), it randomly tells me that I don't have the video drivers to play it and the video will fail until I restart osu!.

Doesn't this require approval from the developer camp?

My laptop can't. At least not when something else is taking up CPU already.
:(

But then again I have to disable videos for osu! already, since I get massive fps spikes if I don't.

You got something against my desktop? Look, its specs are amazing!

1.8Ghz AMD single core CPU that's so fucking old I don't know its name
Radeon 9550
2GB DDR1 RAM
50-ish GB HDD

As you can see, it's very modern and powerful but can't even do 480p at 120+FPS. Fuck off. >:(

Forking over the dough for a modern mainstream laptop last week was 100% worth it.

Alright, we're getting a bit off-topic. My proposal is to change our video rules to:

- Max video dimensions to 1280x720.
- Max video size to 16 MB.

Thoughts?

Size is irrelevant. You can't submit a set above 25MB anyway.

Good point.

Proposed change:

The video's dimensions must not exceed 800x600 for the 4:3 format, or 854x480 for the 16:9 widescreen format. This is so video files keep a decent filesize and do not increase the beatmap's size by too much.
becomes...
The video's dimensions must not exceed 1280x720. This ensures video files do not become excessively large or resource intensive.

I'm pretty sure there's nothing in the client preventing addition of 720p video (unlike the background resolution), but can someone double-check?

720p isn't a very common computer resolution so it doesn't really strike me as a good cap; most people play osu! on computer monitors, not TVs. I would go with 768p max with 720p recommended for your typical anime and other 720p material.

EDIT: Also, have a clause that says that SD stuff must still be in SD.

I think most video material is 720p though; I can't think of any immediate cases where video content is made in 768p, and I'd like to stop silly people upscaling 720p content to 768p just because "I want it as high as possible".

Not quite sure what you mean here; isn't SD stuff by definition SD...?

That's true, some people are really stupid about upscaling. That would be for 1080p stuff down to 768p but that would be rarer than poopoo heads upscaling.

By that clause I mean to stop silly people from upscaling SD stuff to 720p for no reason.

As a side note, 720p refers to a widescreen format (1280/720). What I think Ekaru wanted 1024 x 768 which could work in an updated 4:3 rule.

From that, I think the updated should look like:

The video's dimensions must not exceed 1024x768 for the 4:3 format, or 1280x720 for the 16:9 widescreen format. This is so video files keep a decent filesize and do not increase the beatmap's size by too much.

For 4:3, you almost never see any video above 800x600 being encoded even. By the time widescreen resolution became the standard, highest encodes were in 800x600, where most common were 640x480.

Widescreen 768p is what you often see in lower-cost laptops. It's the computer equivalent of 720p. However, about the only time you would go with 768p is if you're downscaling from 1080p, and most videos nowadays are from 720p anime so it would be extremely likely to see idiots upscaling 720p to 768p just because they can. 4:3 768p would only be useful for like flash stuff.

I say set 720p as cap and have a "Don't upscale" clause.

Okay, sorry I was being silly.

I guess going with what kyto wrote was fine. (not sure how to write the don't upscale clause, but technically not all upscales are bad)

Yes, osu.
My PC handles 720p with LAV and MADVR fine, but doesn't handle 480p osu vids? Something doesn't seem right.

The video's dimensions must not exceed 1280x720. As well, upscaling lower resolution video to a higher resolution should be avoided. This ensures video files do not become excessively large or resource intensive.

Alright, this is the final proposed rule. If no one has issues with it, we'll go forward with this change in a few days.
