[Concise Tutorial] 5 Tips for your video voiceover

Howdy! As we provide different tips and tricks for making your product video well, some audience have sent message to us for help of doing voiceover. So in today’s Concise Tutorial, we have 5 tips to make your voiceover work easy and nicely done. Let’s begin!

1. Start recording before beginning the shoot

Many people may think that if you want to do voiceover, you hit the record button as soon as you start. While it’s quite intuitive, in fact you will lost the first few words if you do so, as our body reacts less than a second later in general. But this little delay will greatly affect the recording, making you stop and do it again.

A better way do the recording is to start recording your voice about 2~3 seconds before you actually start. This will help you start more confortable, as well as the de-noising process mentioned later.

2. Keep your voice in the right style

Well, this needs some skills because most of us are not professional in voicing.

Before you start the voiceover, you need to understand the type and the plot of the video, and what kind of emotion is involved in it.

After you have a thorough look into the video, you can divide the script to different parts if you need to, to keep your voicing style the same in the particular section, and the emotion goes well throughout the whole video.

3. Don’t panic if there’s minor difference from the script

Even the seasoned voice actors can make mistakes in the voicing process, let alone us. But that doesn’t mean you should avoid the mistake all the time.

Sometimes you may notice that some of the words you say don’t match the script, and you will hesitate or immediately stop to request another take to do it well. That will take more time to finish the voiceover.

In fact, if the minor difference doesn’t change the meaning of the original script, or affect the understanding of the plot, just keep going without hesitation – the script just acts like a reference to keep the plot going in a right direction, and doesn’t need to be 100% followed if not specific.

If you do make major mistakes in one of the sections, you can immediately stop, then try to read the whole sentence or section a few more times to make it more fluent, or to understand where you should stress or how fast you should voice it. You literally learn from the mistakes in this process.

4. Remove the noise in the background

OK, now that you have all the tracks voiced, it’s time to do some preparation before inserting the voicing tracks into the video. De-noising, or removing the noise in the background is one of the most important step.

It’s ideal place to do the voiceover is the recording studio where it has better soundproof and equipment that bring less background noises, making the voicing tracks clear and sounds professional. But most of us are unable to do it in the studio, and usually in a closed room with little environment noise. De-noising is now important at this situation.

Most of the sound processing softwares, like Adobe Audition, GoldWave, Audacity and Samplitude, have professional de-noising filters. These filters usually require selecting a section of background noise (usually the 2~3 seconds silence before you start speaking), and start analyze the specification of the noise. When the analyse done, you can select the whole track to start the de-noising process.

Usually the de-noised tracks sounds very clear with the default presets. But if you are not satisfied, you can change some parameters before the whole track de-noising, and see if the result is satisfied.

5. Synchronizing the tracks

With all the tracks ready, you can now insert them into the video editing applications, clip the tracks into pieces and put them in the right place. You can also adjust the speed of the voiceover tracks or the original video if needed, but usually not recommended to do this.

With these 5 tips, you can now understand the voiceover better, and do your own if you have the chance. New skills acquired, yippee!

[POLYV Insight] What can we do with live streaming? (Part 3 – Education)

In the previous article of this series, we talked about some possible ways for using live streaming in the field of consumer products, which has a great number of audience and potential conversions.

While consumer products draw most of the spotlight, another important field – education – is also rising for live streaming demands. “Knowledge is power,” and the power is growing strong and more realistic.

Here we list some of the possible scenarios of using live streaming for the education industry. Let’s get started!

I. K-12 & in-class training

Education is vital for the next generation, especially for those under 18. Besides the traditional classroom, we can set up live streaming sessions for Q&A and additional assistance for those who want to learn even more outside the class.

For Q&A sessions, the teachers can answer questions from one or more students. Using the microphone connection feature, the communication between the teacher and the designated student(s) is instant without latency. Or, the teacher can pick up some typical or representative questions to answer, with the help of the chatroom feature, just as most of the live streaming services do.

And for personal assistance or private classes, the teacher can show the presentation along with the narration and in-class Q&A, with the help of the three-way player. Besides, the teacher can set up some key points or questions during the live session, to check if the student has mastered the knowledge taught within the session.

In some major cities, we can even see several online education platforms or education agencies combine these services into an integrated solution, making it an online-offline personal courses, improving the performance even more than tradition classrooms or personal assistances.

II. Skill training

While fundamental education is vital for kids and teenagers, skill training is equally important for college students and in-service staff. With the training needed, they can seek more opportunities for finding jobs as well as promotions.

To meet the need of learning skills in spare time, it is now very popular to do live streaming classes, or to hold webinars after work or on weekends.

The night-time live streaming classes or webinars are mainly for sharing thoughts, skills, or case studies. They are not like any kind of the courses in textbooks, K-12 classrooms or university courses, instead they are practical cases and experience that can be used in similar situations, or transplanted to other scenarios.

The bottom line, these live streaming classes/webinars are extension to the knowledge and skills that you have learned over years. Compared to traditional learning or courses, they are more case-oriented and more likely to pinpoint your questions or problems encountered in practice.

III. Studying abroad

Nowadays, more and more parents as well as students themselves have put their eyes on the education resources abroad, mainly universities and colleges for undergraduate, master or Ph.D., while some may focus more on high schools. Studying abroad is now a new trend, not only in China, but also in many other countries.

Some of the high schools, universities and colleges, have come up with the idea of using videos to give a good first impression to the potential foreign students, as well as to promote the advantages studying in their campus.

And, apart from those general introduction videos and open course videos hosted in the website, many schools and colleges now use live streaming to present the daily life of the campus, the communities of different interests, or to have interactions to those potential students who want to have a closer look to the campus and the teachers.

With the help of live streaming presentation and Q&A session, students can have a closer look to the schools they like and make the right call, while the schools can attract the potential students more efficiently than before. This is a win-win situation, and everyone can be happy at the end of the day.

IV. VR/AR Classroom

Have you ever felt bored with the dead silent classroom? Or those dull, lifeless textbooks? Now, with the help of VR and AR technologies, learning is no longer boring nor painful – instead, it’s full of fun.

With the help of VR, you can now explore prehistoric creatures such as dinosaurs and trilobites, experience the story of Grimms’ Fairy Tales or Strange Stories from a Chinese Studio develops, or travel around the world and see the landmarks in real time, without even going out of the classroom.

That’s what VR gets in the upper hand – bringing immersive, extensive experience that texts and simple images can’t provide.

And if you afraid VR is too immersive or easy to get yourself hurt, we have another plan – AR.

No matter you use Hololens, hologram projections, or simply your mobile phones, AR doesn’t separate you from the real world. It just adds different image or animation layers for presentation or note, to help the viewer get knowledge faster and more intuitive.

Besides, AR doesn’t bother you to interact with the real world. You can interact with the virtual characters or animation, while continue receive instructions or read the books you have, no bother.

For this idea, Corning Glass has portrayed it in the A Day Made of Glass series dating back in 2011. In one of the scenes, the students are in a classroom where they can learn animals and plants through a tablet with AR feature.

And for closer cases, a development team in Jiangsu, China has made a first batch of AR textbooks, which can display different characters or portray the plot when students point the camera in their phones to the images, titles or QR codes.

V. Conclusion

There are many more possibilities for the industry of education. We just listed some of the more probable use of live streaming, and we believe there are many more if new demands arise. Video technology has changed the industry a lot over the last decade, and the use of live streaming will be the next game changer.

Now, time for the discussion – what do you think about the use of live streaming in education or training? Let us know in the comment section down below, and stay tune for our next article!
