At the fundamental level, our product is a self-paced video exchange, which educators can use to catch up with their students about anything. It becomes increasingly useful to those students who have missed time out of school, because educators can not only provide learning but also emotional support through videos (body language, feeling of connectedness, etc). Additionally, VideoBit is available on a web browser from basically any device, so it is very accessible.
Through self-paced video exchange we give educators and learners a multi-faceted way to do assignments at their convenience (they record when they want/can, and they access the app from a web browser from any device. The app is designed with simplicity in mind so that anyone can use it.
VideoBit is a web app where users can record videos and send them to others. They can receive video answers, where they can further go into back-and-forth video exchange. You can think of it as a well-organized WhatsApp for video exchange. We are designing it for education with its UX and security.
Our focus on video is with language learning in mind but extends to other subjects and educational elements. Videos provide a chance for educators to track mouth movement, mimics, body language, and other important elements while having 1:1 conversations gives a sense of connection to everyone. Self-paced aspect also makes sure that the participant can take their time to gather the courage to speak up and formulate their speech before saying something.
a) English as foreign language learners, which are 375 million in the World. For many, it is just for convenience, but for many it is a question of survival, to be able to advance in their life and/or career. We help them by giving them a chance to practice speaking, which is a very often underlooked category in language learning. It is not enough to know the words and phrases, learners need to be able to speak as well.
b) Refugees that are adopting in their new countries and communities. There are around 30M refugees in the World. For them, we want to serve as not only a language learning tool where they could learn local languages, but also as a tool to connect them with the local communities and help them get a sense of belonging.
One of our team members had to leave his country with his family, so the problem is very well understood. Addtionally, we do learn more about these problems by speaking to the people affected. We use regular communication and feedback loops.
Other than funds, we would be very interested in connecting with the right partner organizations to advance our app for refugee help and learning. Refugees are a global issue, and no matter how good the solution is, unfortunately, we think that partnerships are as crucial as anything.
We enable a video-first chat. With how the world has changed in the past few years, people are much more connected with their electronic devices, but the old communication methods in text chats, voice calls, real-time video conversations, etc are not the most convenient for many people anymore. Rather, we enable a self-paced video exchange where people still can feel connected but are not pressured in being online or active at specific times.
We believe the World is ready to move to more self-paced video conversations, because real-time video conferencing is not efficient anymore (or ever?) where most of the call will not engage, have their cameras off, etc.
We want to achieve it by helping language learners to learn actual speaking, and refugees to learn languages, culture, and assimilate in their new environments by having self-paced 1:1 video conversations.
At the current level we are measuring registered users and videos created to understand the impact we have on communities. In the future with more active users, we would like to be much more precise with our measurements to be able to track how much we have helped to how many people.
Currently, we are just a core team that met in a hackathon, and in order to stay focused, we have decided to not hire anyone new. Once we do, we will have no boundaries of gender, race, or other elements. As we are a male-founder team, we would be even preferring to hire female personnel
It will be a combination of grants and equity funding to get us cash flow positive. Eventually, we will monetize our solution to businesses and government institutions, but we are currently too early to lay out details.
We help language learners to practice speaking by exchanging short videos. They can make self-paced video conversations with other language learners, or teachers. Video helps to pay attention to mouth movement, mimics, and body language which are crucial in learning any language, and the self-paced aspect of the app helps to gain courage and be concise. We are also building a public page where language learners can connect through videos no matter where they are in the world.

Re above error message when attempting to import into a Premiere CS6 project. I used Media Info to inspect the file's properties as per below. All of the video in my project is 8bit video. Any help is much appreciated..
I had the same problem. I tried to import a jpg file into a Premiere Projet without success. And you were right: the file that I was trying to import was made in a CMYK mode. I have changed the mode and... voilà!!!, the file was imported without problems.
But this parameter is not taken into effect and the resulting video quality is very bad.I have even tried setting related parameters like rc_min_rate, rc_max_rate, etc.. but the video quality is still very low as these related parameters are not taken into effect.
I have found the solution to my problem. In fact somebody who was facing the same problem has posted the solution in ffmpeg(libav) user forum. This seems to work in my case too. I am posting the answer to my own question so that other users facing similar issue might benefit from this post.
Setting the Video Bit Rate programmatically for the H264 Video Codec was not honoured by the libx264 Codec. Even though it was working for MPEG1, 2 and MPEG4 video codecs, this setting was not recognised for H264 Video Codec. And the resulting video quality was very bad.
We need to set the pts for the decoded/resized frames before they are fed to encoder. The person who found the solution has gone through ffmpeg.c source and was able to figure this out. We need to first rescale the AVFrame's pts from the stream's time_base to the codec time_base to get a simple frame number (e.g. 1, 2, 3).
Today when I was using FFmpeg C API to work with an encoder that has ID AV_CODEC_ID_H264, I only rescaled the time fields of the packets to be muxed because it was necessary, but did not rescale the time fields of the decoded image. I set the bit_rate field and the encoder worked according to this.
Without setting bit_rate, the output video stream had a bit rate of 1406 kb/s, but after the bit_rate was set to 9851807 in code, the output's bit rate displayed by ffplay became 5683 kb/s. Not exactly the number I set, but at least much higher.
Only 5DII, 5DIII are supported by Magic Lantern. Both allow raw recording in 14,12,10 bit. Don't expect to make it work out of the box. It needs some adjustments and you may not be lucky with "real-time" preview/liveview.
5D3 is by far the better option. Using splitt recording cam handles up to 145 MByte/s.
Again: Be prepared to invest some time to get things running. And get some fast cards:
The Aura Carver 10.1" HD Digital Frame is a great way to put your portfolio on display and a great way to surface forgotten memories. The colors are vibrant, and the build quality is solid, but the Carver isn't without a few quirks.
Lomography's LomoChrome '92 is designed to mimic the look of classic drugstore film that used to fill family photo albums. As we discovered, to shoot with it is to embrace the unexpected, from strange color shifts to odd textures and oversized grain.
The LowePro PhotoSport Outdoor is a camera pack for photographers who also need a well-designed daypack for hiking and other outdoor use. If that sounds like you, the PhotoSport Outdoor may be a great choice, but as with any hybrid product, there are a few tradeoffs.
If you want a compact camera that produces great quality photos without the hassle of changing lenses, there are plenty of choices available for every budget. Read on to find out which portable enthusiast compacts are our favorites.

Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.
Does anyone know a file manager that allows to show videos bit rates when files are viewed as a list? On Nautilus, I have tried nautilus-columns, and it shows exif for audio files, but not for videos.
