How to upload the right clip on video sharing sites

I frequent a number of video-related forums lately, and this question pops up all the time: what’s the best practice for videos to upload on YouTube and other video sharing sites.

Youtube encodes your video in 320×240 QVGA format and it has a time limit of 10 minutes and 100 MB size per clip. Other sites have similar size or time limitations, but few don’t. Revver re-encodes on 480×360 and Veoh on something close to 500 pixels wide. Here are a few pointers:

1. If your clip is smaller than 10 minutes, you can safely decide to encode it and upload it in VGA 640×480 format. If it’s bigger than 10 minutes, please note that YouTube won’t accept your video. Regardless, if your video is too long select the QVGA exporting size.

2. If your video is widescreen, make sure you use your encoder’s options to create a letterbox. You can choose to not letterbox and instead export using a widescreen size (e.g. 640×360 or 320×180), but depending on the kind of codec you will use, some video sharing sites won’t be 100% compatible recognizing it and they will “stretch” your video vertically making it look ugly. To be on the safe side, learn how to letterbox your videos.

3. If you decided to export in VGA size, use 1024 kbps video bitrate and 64kbps audio. If you went for QVGA, choose 320 kbps video and 64kbps audio.

4. The preferred codec exporting format is mpeg4. Choose either XVid or MP4-Simple profile, with CBR bitrate encoding (VBR bitrate can cause compatibility problems). Avoid WMV, as depending on the encoder used it has A/V sync issues when re-encoded by most video sharing sites.

Useful applications to do the job properly (with letterbox support) is MediaCoder on the PC side and QuickTime Pro on the Mac. FFmpegX won’t letterbox.

iPhone security breach

Haha… So basically, Apple bent over to Cingular to not include support for native apps because –as it’s well known– carriers are afraid of native app stability but mostly security problems, and now they get their full blown security hole from the browser. I can only suggest two things to ATT for that (expected) overreaction over native apps: either remove the browser from the iPhone (*tsk*), or free the damn SDK and let users have native apps instead of useless web “apps”.

Relationships

At the beginning of our relationship we were like most young couples: we would occasionally argue about stuff and we would have about 2-3 major fights per year. But as years go by, things are getting so much smoother. Sure, there is some arguing every now and then that fades away 5 minutes later, but we haven’t had a big fight for more than a year now.

Either we are getting old and too bored to fight (scientifically: sex drive dying), or we learn about and love each other more and more every day. It’s so great being married to the most beautiful man in the world (even if he was a bit grumpy in the pictures ;-) ).

Stanford University

A view of the Stanford campgrounds at Palo Alto, CA, USA. We spent about an hour there yesterday with JBQ and on the way back we stopped at Suraj, an Indian restaurant with lovely lamb dishes, for dinner.

Video shot with a Canon HV20 HD camcorder, a fluid tripod head, an ND-6 filter, a polarizer and Tiffen’s “soft” HDTV/FX-3 filter at 1/60 shutter speed but with variable exposure & aperture settings. 720p HD version of the video available here (”save as” link, 180 MB), or view it via Flash video below.

Update: Of course, that’s “Stanford Campus”. not campground. :P

Best gadgets you could own for the money

Below is a list of gadgets that you should be owning if you already haven’t, given that their prices are fair for the features they bring:

* If you already don’t own a smartphone, get one. The cheapest, but at the same time most well-crafted all-around smartphones are the Nokia Symbian S60 3.1 ones. I would recommend either the Nokia 6120 or the Nokia 5700 as they are the cheapest of all for the features they offer — while running the latest version of the operating system.

* A camcorder. If you just need “a” camcorder, get the Canon ZR800 ($230). If you need HD, then don’t even think getting anything else other than the Canon HV20 ($800). Consumers get it because the Indies get it, and the Indies get it because it’s cheap for what it does.

* Sony MDR-W20 in-ear-but-over-the-head headphones for sports. I can’t find any picture of it online, but we bought a pair yesterday at Frys for just $14, and quality/loudness was extremely good. Better than some other headphones that sell for much more. It’s the only “in-ear” model that actually fits in my ears.

The quest for the elusive “film look”

I see this or this picture and I am getting jealous. There is no consumer small-sized camcorder or even a prosumer one that will give you that background blur out of the box without some serious/expensive tweaking with 35mm adapters and lenses. I (and most other enthusiasts) need a consumer-priced HD camcorder that will give us out of the box that elusive “film look” instead of “Johnny records his dog taking a piss at his living room” look. It is the holy grail of indie filmmaking.

Yeah, I know. The consensus is that cameras that cost less than $20,000+lenses don’t give you that film look out of the box. Which is why there is a whole “geek” filmmaker community that tweaks the hell out of their cheaper cameras to get close to that elusive professional movie look. Now, these guys are just *accepting* the situation, sit tight and do with whatever hardware and software filters they got in their disposal. I can’t just do that. Being the perfectionist that I am I want a product that is able to do exactly what I need. The real problem is that most people think that it is not physically possible to create a small camcorder with good background blur and the right contrast values to achieve the “film look”. That’s what they think.

But in reality, IT CAN be done. And it can be done by using a big APS/DSLR-sized sensor (or bigger) instead of the tiny sensors currently found on the consumer/prosumer camcorders. If you have a big sensor and a good-enough built-in lens, you can achieve the film look just fine — and without ugly hacks. Problem is, nobody manufactures such a camera, possibly because of the following five reasons:

1. In order to achieve good background blur in a small-sized body you need to sacrifice the zoom. For example, while even the cheapest camcorder will be able to do 24x optical zoom, such a camcorder I am proposing wouldn’t go above 4x. It’s how it is. But the thing is, that’s acceptable! Such a camcorder would be used by filmmakers and enthusiasts, not tourists who would want to zoom to the Great Wall of China from 2 miles away. IMO, Companies are *afraid* to release a camcorder with only a 4x zoom, it’s a risk of their image.

2. Creating a big sensor, is more expensive than creating a smaller one. You see, the bigger the chip physically, the more “dust” & “errors” it can accumulate during manufacturing resulting in a higher amount of “bad” chips straight out of the factory. However, while price would be higher, don’t expect it to be more than 30% than let’s say, Canon’s tiny Digic-II.

4. They are afraid that such a $1000 camera would kill their $3500 cameras.

5. They are idiots. They never did a market research to try fill up that niche, or their ‘ingenious’ engineers never thought about the problem.

To backup my claims, here are two digital *still* cameras that have the hardware features I am after: the Sony DSC-R1 and the Sigma DP1. These guys recognized that there was such a specific niche in the digital photography and they created the appropriate cameras — although they are not well-sold because in the digital photography space you can get a DSLR plus the right lens that will give you background blur for less than $1000, so it makes sense to go for a DSLR rather than these specialized digicams. But in the camcorder space there is no “DSLR equivalent” for a thousand bucks, so such a product would immediately catch on with enthusiasts. And yet, no one has created anything like that…

In my opinion, such a camcorder would easily sell for $1000 with a bad-ass body look similar to this and the following features: 1920×1080 24/30p, 1440×1080/60i, 1280×720 24/30/60p, Compact Flash as a medium, h.264 recording format (even if it doesn’t create as good quality as HDV’s mpeg2), no need for viewfinder, flexible focus, image stabilization, enough manual options and other standard conveniences. As long as I get my background blur out of the box, I don’t need support for external lenses, although if the right steps would be taken during design, they could make it easier for accessory companies to create 35mm adapters for lenses — although this could just be an extra option.

For those who don’t have enough experience with optics are probably thinking “Eugenia is dreaming, if such camcorder doesn’t exist there is a good reason why it doesn’t“, but that isn’t true. I am ranting over this because the technology to create such a camcorder (on the cheap even) exists and there is an established niche market for it too. It’s just that no one took the steps to put the pieces together and create one for some strange reason. If someone decides to go for it, it would be similar to what Google did with Gmail. Here you had about 100 email services online competing with each other giving from 1 to 10 MBs of online email space, and then, there you had Google coming out of the blue giving away 1 GB. They blew their competition away without using any alien technology, but just by going “big”. I am just waiting for that company — or department at Canon — to go for it too.

The RED guys have announced that they are going to be releasing a “pocket professional camera” next year, so let’s hope that it’s designed with that in mind — and in the right price.

Update: Good discussion with directors and cameramen about the issue.

No hardware acceleration

I just found out that Quicktime crashing when loaded in a Firefox/browser on the secondary rotated screen is primarily NVidia’s fault. Apparently when you rotate the screen, the driver does not enforce hardware acceleration on that screen. Joost, Flash and games are choppy when played on my secondary rotated screen. The bug exists for at least 2 years, and a freeware utility that supposedly helps setting the right attributes to Windows to use acceleration, it doesn’t. ATi’s driver didn’t have this dual-monitor/rotation bug (it had others).

Stupid fingers

The Tiffen HDTV/FX-3 filter arrived today for my camcorder, and I was so happy about it. Then, I tried to remove it at some point, but I hadn’t screwed it on all the way earlier, so it “fell” on my hand. Now, the filter has finger marks on it. Thankfully, JBQ has the right equipment to clean it up so I can use it this weekend. Bummer. :(

Too Many Linux Distros Make For Open Source Mess

“Too Many Linux Distros Make For Open Source Mess”, says Inforworld. Well, duh. I have been saying this since Day 1. I like focus and direction on software, and GNU/Linux is anything but. If all these distros and developers had a forum to work together instead of forking or re-inventing the wheel every six months, Linux would have erased Microsoft from the map by now. While some people perceive this mess as “choice”, I am a more practical and “show me the results” kind of girl, so I am not compatible with that point of view — although it is a point of view that I respect.

It’s all in our heads

Fashion, or what’s “proper”, is just a thing we have totally invented. It’s not something real. Back in 1987 Florence Griffith-Joyner expressed her desire to run in a bikini-like suit, and she was denied that by the IAAF. In fact, they told her that will fine her if she does. Today, everyone wears those and no one gives a monkey about it. Here’s Flora Rentoumi of Greece on a race yesterday.
